High Innovation-Cost Makes Cancer Drugs Dear: A Fragile Argument?

Cancer is a major cause of high morbidity and mortality in India, just many other countries, according to a report of the World Health Organization (W.H.O). While deaths from cancer worldwide are projected to continue to rise to over 1.31 million in 2030, the Indian Council of Medical Research (ICMR) estimates that India is likely to have over 1.73 million new cases of cancer and over 8,80,000 deaths due to the disease by 2020 with cancers of breast, lung and cervix topping the list.

 Cancer treatment is beyond the reach of many:

Despite cancer being one of the top five leading causes of death in the country, with a major impact on society, its treatment is still beyond the reach of many. There are, of course, a number of critical issues that need to be addressed in containing the havoc that this dreaded disease causes in many families –  spanning across its entire chain, from preventive measures to early diagnosis and right up to its effective treatment. However, in this article, I shall focus only on the concern related to affordable treatment with appropriate cancer with medicines.

To illustrate this point, I shall quote first from the address of the Chief Minister of Maharashtra during inauguration of Aditya Birla Memorial Hospital Cancer Care Center on November 26, 2016. He said: “Cancer is the dreadful disease of all the time and for Maharashtra it is a big challenge as we are infamously at number two position in cancer cases in the country as after Uttar Pradesh, most cases are found here.” Incidentally, UP is one of the poorest state of India.

Underscoring that the biggest challenge before the technology is to bring down the cost of the cancer treatment and make it affordable and accessible for all, the Chief Minister (CM) further observed, “although, technological innovation has increased in last one decade, the accessibility and affordability still remain a challenge and I think, we need to work on this aspect.”

A new cancer drug launch vindicates the CM’s point:

The Maharashtra CM’s above statement is vindicated by a national media report of September 13, 2017. It said, Merck & Co of the United States have launched its blockbuster cancer drug ‘Keytruda’ (pembrolizumab) in India, around a year after its marketing approval in the country. Keytruda is expected to be 30 percent cheaper, compared to its global prices, costing Rs 3,75,000 – 4,50,000 to patients for each 21-day dose in India.

The point to take note of, despite being 30 percent cheaper, how many Indian patients will be able to afford this drug for every 3 weeks therapy? Doesn’t it, therefore, endorse the CM’s above submission? Well, some may argue that this exorbitant drug price is directly linked to high costs for its innovation and clinical development. Let me examine this myth now under the backdrop of credible research studies.

Cancer drugs are least affordable in India – An international study:

On June 6, 2016, by a Press Release, American Society of Clinical Oncology (ASCO) revealed the results of one of the largest analyses of differences in cancer drug prices between countries worldwide. The researchers calculated monthly drug doses for 15 generic and eight patented cancer drugs used to treat a wide range of cancer types and stages. Retail drug prices in Australia, China, India, South Africa, United Kingdom, Israel, and the United States were obtained predominantly from government websites. The study shows that cancer drug prices are the highest in the United States, and the lowest in India and South Africa.

However, adjusting the prices against ‘GDPcapPPP’ – a measure of national wealth that takes into consideration the cost of living, cancer drugs appeared to be least affordable in India and China. The researchers obtained the ‘GDPcapPPP’ data for each country from the International Monetary Fund and used it to estimate the affordability of drugs.

Why are cancer drug prices so high and not affordable to many?

The most common argument of the research based pharma companies is that the cost of research and development to bring an innovative new drug goes in billions of dollars.

The same question was raised in a series of interviews at the J.P. Morgan Healthcare Conference, published by the CNBC with a title “CEOs: What’s missing in the drug pricing debate” on January 11, 2016, where three Global CEOs expressed that the public is getting overly simple arguments in the debate about drug pricing. All three of them reportedly cited three different reasons altogether, as follows:

  • Eli Lilly CEO said, “Some of the noise you hear about drug pricing neglects the fact that we often must pay deep discounts in a market-based environment where we’re competing in many cases against other alternative therapies, including those low-cost generics.”
  • Pfizer CEO took a different approach by saying, “if you look at the market, about a decade ago, 54 percent of the pharmaceutical market was genericized; today 90 percent is genericized.”
  • However, as reported by CNBC, Novartis CEO Joseph Jimenez, focusing on innovation and in context on cancer drugs, argued “innovation has to continue to be rewarded or we’re just not going to be able to see the kind of breakthroughs that we have seen in cancer research, specifically regarding the uses and benefits of the cancer-fighting drug Gleevec. We continued to show that the drug was valuable in other indications in cancer and so we needed to be reared for that innovation and we’re pricing according to that.”

Is drug innovation as expensive and time intensive as claimed to be?

An article titled, “The high cost of drugs is the price we pay for innovation”, published by the World Economic Forum (WEF) on March 28, 2017 reported, “15 spenders in the pharmaceutical industry are investing about US$3 billion in R&D, on average, for each successful new medicine.”

The November 18, 2014 report on the ‘Cost of Developing a New Drug,’ prepared by the Tufts Center for the Study of Drug Development also announced: “The estimated average pre-tax industry cost per new prescription drug approval (inclusive of failures and capital costs) is: US$ 2,558 million.”

Not everybody agrees:

Interestingly, Professor of Medicine of Harvard University – Jerry Avorn questioned the very basis of this study in the article published in the New England Journal of Medicine (NEJM) on May 14, 2015. It’s not just NEJM even the erstwhile Global CEO of GSK – Sir Andrew Witty had questioned such high numbers attributed to R&D cost, around 5 years ago, in 2013. At that time Reuters reported his comments on the subject, as follows:

“The pharmaceutical industry should be able to charge less for new drugs in future by passing on efficiencies in research and development to its customers. It’s not unrealistic to expect that new innovation ought to be priced at or below, in some cases, the prices that have pre-existed them. We haven’t seen that in recent eras of the (pharmaceutical) industry, but it is completely normal in other industries.” Quoting the study of Deloitte and Thomson Reuters on R&D productivity among the world’s 12 top drugmakers that said the average cost of developing a new medicine, including failures, was then US$ 1.1 billion, Witty remarked, “US$ 1 billion price-tag was one of the great myths of the industry.”

A decade after Sir Andrew’s comment, his view was virtually corroborated by yet another research study, published this month. The study reemphasized: “The Tufts analysis lacks transparency and is difficult to judge on its merits. It cannot be properly analyzed without knowing the specific drug products investigated, yet this has been deemed proprietary information and is governed by confidentiality agreements.” I shall discuss this report briefly, in just a bit.

The latest study busts the myth:

The latest study on the subject, titled “Research and Development Spending to Bring a Single Cancer Drug to Market and Revenues After Approval”, has been published in the ‘JAMA Internal Medicine’ on September 11, 2017. It busts the myth that ‘high innovation-cost makes cancer drugs dear,’ providing a transparent estimate of R&D spending on cancer drugs. Interestingly, the analysis included the cost of failures, as well, while working out the total R&D costs of a company.

The report started by saying: “A common justification for high cancer drug prices is the sizable research and development (R&D) outlay necessary to bring a drug to the US market. A recent estimate of R&D spending is US$ 2.7 billion (2017 US dollars). However, this analysis lacks transparency and independent replication.”

The study concludes: “Prior estimates for the cost to develop one new drug span from US$ 320.0 million to US$ 2.7 billion. We analyzed R&D spending for pharmaceutical companies that successfully pursued their first drug approval and estimate that it costs US$ 648.0 million to bring a drug to market. In a short period, development cost is more than recouped, and some companies boast more than a 10-fold higher revenue than R&D spending—a sum not seen in other sectors of the economy. Future work regarding the cost of cancer drugs may be facilitated by more, not less, transparency in the biopharmaceutical industry.” The researchers also established that ‘the median time to develop a drug was 7.3 years (range, 5.8-15.2 years).’

“Policymakers can safely take steps to rein in drug prices without fear of jeopardizing innovation”:

NPR – a multimedia news organization and radio program producer reported: In an invited commentary that accompanies the JAMA Internal Medicine analysis, Merrill Goozner, editor emeritus of the magazine Modern Healthcare, noted that “the industry consistently generates the highest profit margins among all U.S. industries.” Goozner argues that the enormous value of patent protection for drugs far outweighs the inherent riskiness of pharmaceutical research and development, and agrees with the study authors when he writes: “Policymakers can safely take steps to rein in drug prices without fear of jeopardizing innovation,” NPR wrote.

Conclusion:

So, the moot question that surfaces: Is Pharma innovation as expensive and time consuming as claimed to be? If not, it further strengthens the credibility barrier to Big Pharma’s relentless pro-innovation messaging. Is the core intent, then, stretching the product monopoly status as long as possible – with jaw dropping pricing, unrelated to cost of innovation?

Further, incidents such as, shielding patent of a best-selling drug from low priced generic competition, by transferring its patents on to a native American tribe, probably, unveil the core intent of unabated pro-innovation messaging of major global pharma companies. In this particular case, being one among those companies which are seeking to market cheaper generic versions of this blockbuster eye drug, Mylan reportedly has decided to vigorously oppose such delaying tactic of Allergan before the Patent Trial and Appeal Board.

As a cumulative impact of similar developments, lawmakers in the United States are reportedly framing new laws to address the issue of high drug prices. For example, “California’s Senate Bill 17 would require health insurers to disclose the costs of certain drugs and force pharmaceutical manufacturers to detail price hikes to an agency for posting on a government website. The proposal would also make drugmakers liable to pay a civil penalty if they don’t follow its provisions.”

The myth of ‘high innovation-cost makes cancer drugs dear’ will go bust with such revelations, regardless of the blitzkrieg of self-serving pro-innovation fragile messaging.  Alongside, shouldn’t the Indian Policy makers take appropriate measures to rein in cancer drug prices, being free from any apprehension of jeopardizing innovation?

Dawns A New Era: Regenerative Medicine For Degenerative Disease

Posted on by

Could breakthrough innovation in ‘Regenerative Medicine’ significantly reduce the need of expensive lifelong medications, or even make the use of some important medical devices less relevant, or even help avoiding expensive and risky surgical interventions? The common answer to these critical questions is now getting clearer, in tandem with the rapid progress of the science of ‘Regenerative Medicine.’

On June 13, 2017, Nature Biomedical Engineering published an interesting an article titled, “3D-printed vascular networks direct therapeutic angiogenesis in ischemia.” In simple words, these 3D-Printed patches are going to usher in a highly innovative way to treat ischemic diseases, in the future. As the researchers highlighted, arterial bypass grafts are currently considered as the gold standard for the treatment of end-stage ischemic disease, though many patients are unable to tolerate the cardiovascular stress of arterial surgery. The researchers found that implantation of 3D-printed grafts containing endothelial-cell-lined lumens, induces spontaneous and geometrically guided generation of collateral circulation in ischemic settings.

In rodent models of hind limb ischemia and myocardial infarction, these scientists successfully demonstrated that the vascular patches rescue perfusion of distal tissues, preventing capillary loss, muscle atrophy and loss of function.

In this article, I shall deliberate on the importance of this discovery, and its overall future implications on a broader perspective.

Regenerative medicine:

Here comes the basic question – What is ‘Regenerative Medicine’?

It is defined as a highly innovative branch of medicine that develops implementable methods to regrow, repair or replace damaged or diseased cells, organs or tissues. According to RegerativeMedicine.net following are illustrations of some conditions or diseases that regenerative medicine has the potential to cure, and what their current state of treatment looks like in in the American perspective:

  • Heart valves- 250,000 patients receive heart valves, at a cost of US$27 billion annually
  • Heart disease and Stroke- 950,00 people die of heart disease or stroke, at a cost of US$ 351 billion annually
  • Diabetes- 17 million patients have diabetes, at a cost of US$ 132 billion annually

I discussed in this blog, the subject of ‘3D Printing in health care’ on January 11, 2016. Hence, won’t dwell on that subject here

Ischemia, and the relevance of the above discovery:

Ischemia, as many would know, is a condition that restricts adequate flow of blood in some parts of our body, which over a period, may narrow, harden or even block the important blood vessels, much often resulting in stroke, heart attack or other related life-threatening vascular disorders.

Currently, ischemic heart conditions are usually treated either with blood thinning drugs, or blood vessel relaxants. In more serious stages of this condition, doctors prefer angioplasty or other surgical interventions, such as coronary artery bypass.

In this broad perspective, the relevance of the above discovery in addressing various debilitating or life- threatening ischemic conditions, is profound. Its novelty lies in the ability of the scientists making a 3D-printed patch that can be infused with cells to help grow healthy new blood vessels.

An emerging medical space:

The science of ‘Regenerative Medicine’ is increasingly being considered as an emerging medical space aimed at the treatment of those diseases that are usually classified as degenerative, incurable and irreversible. As it appears today, this science has the potential to unfold a new paradigm in this space, where patients can expect cure for many serious ailments, such as, spinal injuries, heart disease, Parkinson’s, Alzheimer’s disease and even diabetes, besides many others.

One more recent pursuit in this much uncharted frontier was reported in the British news daily – ‘The Telegraph’ on February 21, 2017, revealing the outcome of a path-breaking medical study for freezing the progression of a crippling ailment called Multiple Sclerosis (MS). This research followed a unique Stem Cell (SC) transplantation process, and is regarded as the largest long-term follow-up of SC transplantation treatment study of MS in regenerative medicine.

This study, spearheaded by Imperial College London, established that 46 per cent of patients who underwent the treatment did not suffer a worsening of their condition for five years. The process works by destroying the immune cells responsible for attacking the nervous system. This is indeed a very significant development in the space of medical research.

The treatment, called autologous hematopoietic stem cell transplantation (AHSCT), was given to patients with advanced forms of MS who had failed to respond to other medications. However, the researchers noted that the nature of the treatment, which involves aggressive chemotherapy, carried “significant risks”.

As many would know, MS is caused by the immune system malfunctioning and mistakenly attacking nerve cells in the brain and spinal cord, leading to problems with movement, vision, balance and speech. It’s a lifelong condition and often causes serious disability, with no cure still in sight. The disease is most commonly diagnosed in people in their 20s and 30s, although it can develop at any age.

A potential game changer:

According to California Institute for Regenerative Medicine (CIRM), this procedure has a game changing potential for successful use:

  • To replace neurons damaged by spinal cord injury, stroke, Alzheimer’s disease, Parkinson’s disease or other neurological problems
  • To produce insulin that could treat people with diabetes, and heart muscle cells that could repair damage after a heart attack, or
  • To replace virtually any tissue or organ that is injured or diseased

Research on “Regenerative Medicine’ signals a new hope:

Following are examples of just a few more promising developments, indicating that research in ‘Regenerative Medicine’ is taking rapid strides, signaling a new hope:

- A cure for Type 1 diabetes:

According to an international report on October 9, 2014, for the first time after 23 years of research, Harvard University has been able to manufacture millions of beta cells required for transplantation. It could mean a cure for diabetes, and the end of daily insulin injections for patients living with Type 1 diabetes. Although, just around 10 per cent of all diabetes is Type 1, it is the most common type of childhood diabetes.

The report indicated, the stem cell-derived beta cells are presently undergoing trials in animal models, including non-human primates, where they are still producing insulin after several months.

Another report of April 2014 indicates that for the first time, scientists have successfully replaced the damaged DNA of a type 1 diabetes sufferer with the healthy genetic material of an infant donor. When these cells are injected back into the diabetic patient, it is expected that they will begin to produce insulin on their own.

- Restoring vision in macular degeneration:

Yet another study published in ‘The Lancet’ in October 2014 stated that scientists in the United States have announced that single transplant of stem cells has helped restore the sight of patients suffering from incurable forms of blindness due to Age-related Macular Degeneration (AMD). Currently no effective treatments exist for this eye disorder, which can cause complete blindness due to the loss of light-receiving photoreceptor cells in the retina.

To recreate a type of cell in the retina that supports those photoreceptors, the new treatment uses stem cells derived from embryos that are only a few days old and have the ability to develop into any kind of tissue in the body. However, the transplants have proved controversial because they use stem cells derived from spare human embryos left over from IVF treatment.

- A cure for heart failure:

One more international report of May 01, 2014 states, by injecting human stem cells into the organs of macaque monkeys, scientists have been able to regenerate their damaged hearts by up to 40 per cent in just a few weeks. Thus, it appears now that a cure for heart failure could be just a few years away and would mean that even people who are “bed-bound” with heart failure could be “up and about” again within a few weeks.

As on date, the heart muscle cannot be repaired, making people with severe heart failure necessarily wait for a heart transplant, provided the patients are willing, and can afford so.

Conclusion:

There is a host of diseases, including several chronic ailments, such as diabetes, heart conditions, rheumatoid arthritis, or some types of cancer, which can’t be reversed, however, could be managed with a lifelong treatment. For most of these diseases, ‘Regenerative Medicine’ has the potential to be a game changer by transforming many lives.

Moreover, ‘Regenerative Medicine’ is expected not just to bring down the cost of health care and the disease burden significantly, but would also help increasing the economic productivity of a nation considerably.

Currently, medical research of the highest order in this area, has mostly been conducted by various academia of global repute, along with a few in the industry. It should soon involve, besides patients, several industries, including pharmaceuticals and biotech sectors, in a big way.

Nevertheless, this emerging trend sends a clear signal that to treat various chronic, incurable, irreversible and seriously debilitating degenerative diseases ‘Regenerative Medicine’ is now poised to take a giant leap in the health care space.  In that process, it would possibly help healing various ailments in a more meaningful, providing a cure for many chronic diseases that was a badly missing piece in the medical science, so far.

Thus, ‘Regenerative Medicines’ to treat many ‘Degenerative Diseases’ signal a great potential to give an altogether new shape and dimension to the future of global health care. It is also expected to ensure lesser lifelong usage of expensive drugs, setting a new normal to bring back the patients’ lives back to the pre-disease state.

Could Vaccine Prevent Heart Attacks?

Posted on by

Could Vaccine Prevent Even Heart Attacks? The question may sound weird to many, but it really appears so, possibly reducing further need of several expensive medications for lifelong use. A good number of academic institutions, besides some biotechnology companies, are taking rapid strides in the newer areas of vaccine development to protect people from various non-infectious serious ailments, including some fatal disorders, such as heart attacks.

In this article, I shall deliberate on this area.

Picking up the thread:

One of the critically important preventive therapy to save millions of precious lives is – vaccination.  Way back in 1796, Edward Anthony Jenner not only discovered the process of vaccination, but also developed the world’s first smallpox vaccine to save mankind from this highly infectious and life-threatening disease. As per published data, prior to this discovery, the mortality rate for smallpox was as high as up to 35 percent.

Very appropriately, Jenner is often referred to as the “Father of Immunology”, whose pioneering work has saved more lives than the work of any other person, in that era. Later, in 1901 Emil Von Behring received the first Nobel Prize (ever) for discovering Diphtheria serum therapy for yet another highly infectious disease, affecting mostly infants and children.

Nevertheless, the pioneering work of Edward Anthony Jenner laid the primary substructure of immunology, which continued to be developed as a robust prophylactic measure against various types of, initially infectious and communicable diseases.

Expanded scope for vaccines:

Gradually, the global focus of vaccine development started expanding from prophylactic vaccination for communicable disease such as smallpox, diphtheria, malaria and pneumonia; to non-infectious disorders, like cancer, diabetes and atherosclerosis that often leads to heart attacks and strokes; including several therapeutic vaccines, especially for cancer. The list continues.

In other words, from inducing long-life immunity against exogenous or foreign antigens in infectious diseases caused by microorganisms, to inducing similar immune reaction against the body’s own molecules, which are responsible for precipitating seriously debilitating or life-threatening pathological changes. These include conditions, such as cardiovascular or metabolic disorders and many other chronic ailments, including various types of the deadly disease – cancer.

Would vaccines prevent even heart attacks?

Let me now get back to where I started from: Would vaccines prevent even heart attacks?

Medical experts often say, until a sudden heart attack occurs, patients with atherosclerosis may show no symptoms for decades. This epitomizes the seriousness of this disorder in human population.

Since long, atherosclerosis used to be considered as ‘a lipid-driven disease caused by the continuous accumulation of cholesterol in the arterial intima.’ However, that concept is changing now based on enough scientific evidences. These clearly indicate that ‘atherosclerosis is predominately a chronic low-grade inflammatory disease of the vessel wall with an interplay of humoral, cellular, and locally produced pro-inflammatory factors.’

Atherosclerosis is a chronic low-grade inflammatory disease:

In the above context, a recent research study has arrested the attention of many medical scientists, including several top cardiologists, across the world. This article, published on June 19, 2017, in the peer-reviewed European Heart Journal reported the development of a vaccine that induces an effective immune response in mice to significantly reduce plasma lipids, systemic and vascular inflammation, and atherosclerosis lesions in the aorta.

Leverages the immune system of the body:

In simple words, this cholesterol-lowering vaccine demonstrates how the immune system of the body can be leveraged to lower blood lipids, signaling a strong potential to make drugs, such as statins, possibly irrelevant.

This is the first intervention study based on a well-established, translational mouse model for hyperlipidemia and atherosclerosis. The research found, as compared with the control group, the vaccine reduced total and LDL cholesterol levels in the mice, as well as reduced signs of fatty build-up in the arteries.

Potentially an effective and economical approach:

The authors believe, the vaccine may represent an effective and economical approach, with higher patient compliance, in the treatment and prevention of similar cardiovascular pathologies. Taking the study to its next stage, they have already enrolled human volunteers to conduct the phase one study, for a detailed scientific assessment on how this vaccine will work for the patients suffering from similar disorders.

Another interesting development:

To give just a flavor of the progress of vaccine development in several areas of serious and life-threatening non-communicable diseases, I am quoting below the following interesting study:

June 1, 2016 issue of ‘The Independent’ reported that scientists of Johannes Gutenberg University in Germany have taken a “very positive step” towards creating a universal vaccine against cancer that makes the body’s immune system attack tumors as if they were a virus. The researchers had taken pieces of cancer’s genetic RNA code, put them into tiny nanoparticles of fat and then injected the mixture into the bloodstreams of three patients in the advanced stages of the disease. The patients’ immune systems responded by producing “killer” T-cells designed to attack cancer.

This vaccine was found to be effective in fighting “aggressively growing” tumors in mice. At the same time, such vaccines are fast and inexpensive to produce, and virtually any tumor antigen (a protein attacked by the immune system) can be encoded by RNA, the report said.

How expensive are the R&D costs for vaccines?

In this context, an important related question may well be raised: How expensive are the R&D costs for vaccines? According to a paper published by the US National Library of Medicine and National Institute of Health (NIH):

“A vaccine candidate entering pre-clinical development in 2011 would be expected to achieve licensure in 2022; all costs are reported in 2022 Canadian dollars (CAD). After applying a 9 percent cost of capital, the capitalized total R&D expenditure amounts to $ 474.88 million CAD.” 

Some key issues and challenges:

Scientific breakthroughs in genetics and biotechnological research, supported by state of art tools related to information technology, a wide range of vaccine development initiatives, targeting both in infectious and non-infectious diseases, are making rapid progress. However, as I had said before, there are some key issues and challenges that need to be addressed, simultaneously. A few examples of which are as follows:

  • Actual cost of vaccines goes much beyond their R&D expenses. This is mainly because of dedicated and highly specialized manufacturing facilities required for their mass-scale production, and then for the distribution of the same, mostly using cold-chains.
  • Around 60 percent of the production costs of vaccines are fixed in nature (National Health Policy Forum. 25. January 2006:14). Thus, such products will need to have a decent market size to be profitable.
  • Unlike many other medications for chronic ailments, which need to be taken for a long duration, vaccines are administered for a limited number of times, restricting their business potential.

Full neutralization of this cost before keeping a modest margin, could make such high-end vaccines relatively expensive for patients, without adequate financial incentives from the Government.

In conclusion:

The discovery of the interesting vaccine to prevent both fatal and non-fatal heart attacks followed an interesting path, and took a long time of around one and a half decade to go for the phase I human trial. Putting together the facts from the available scientific literatures, the long and arduous path of this journey may be, I reckon, summed up, as follows:

An article published by the Harvard Stem Cell Institute (HSCI) on June 9, 2014 first reported that it’s plausible to prevent heart attacks with vaccination. Nonetheless, it all started even much before that, when in 2003, a group of researchers in France studying families with very high cholesterol levels and very early heart attacks, discovered a specific cholesterol regulator. Mutations in the related gene seemed to be responsible for very high cholesterol levels, and early heart attacks. Further research on the subject continued thereafter, based on this novel finding.

Thereafter, in 2014, HSCI scientists collaborating with researchers at the University of Pennsylvania developed a “genome editing” approach for permanently reducing cholesterol levels in mice with a single injection, potentially reducing heart attack risk by up to 90 percent, reported this Harvard article. ‘Circulation Research’ – a journal of the American Heart Association, published the study online on June 10, 2014.

Currently, in mid 2017, from the article published in the peer-reviewed ‘European Heart Journal’ we get to know that development of a vaccine that can prevent heart attacks is going for phase I clinical trial, following several well-tested and scientific evidence based promises.

The outcome of the final phases of this study will now be keenly followed by the experts. Others will optimistically wait for the D-day – virtually the dawn of a new paradigm of preventing heart attacks through vaccination, well before it can result into any fatal or crippling consequences.

Making New Cancer Drugs Cost-effective

Posted on by
Reply

The prices of new cancer drugs are increasingly becoming unsustainable across the world, and more so in India. A sizable number of poor and even middle-income patients, who spend their entire life’s savings for the treatment of this dreaded disease, is pushed towards extreme economic hardship. Their plight in India would continue to remain so, till Universal Health Care (UHC) comes into force, as enunciated in the National Health Policy 2017.

Thus, the delivery of affordable and equitable cancer care poses one of India’s greatest public health challenges. Public expenditure on cancer in India remains below US$ 10 per person, as compared with more than US$ 100 per person in high-income countries. The May 2014 paper, published in ‘The Lancet Oncology’, analyzed this concern in detail.

In this article, after giving a brief backdrop, I shall explore a possible alternative to make cancer treatment with new drugs affordable to many by scaling up this strategic option.

Cancer – the second leading cause of death:

According to the World Health Organization (W.H.O), cancer is the second leading cause of death globally and accounted for 8.8 million deaths in 2015. This works out to nearly 1 in 6 of all global deaths, with US$ 1.16 trillion being the estimated total annual economic cost of cancer in 2010. Lung, prostate, colorectal, stomach and liver cancer are the most common types of cancer in men, while breast, colorectal, lung, cervix and stomach cancer are the most common among women. To reduce significant disability, suffering and deaths caused by cancer worldwide, effective and affordable programs in early diagnosis, screening, treatment, and palliative care are needed. Treatment options may include surgery, medicines and/or radiotherapy – the report reiterates. In many instances, anti-cancer drugs are the mainstay treatment.

For the country, Indian Council of Medical Research (ICMR) reported over 736, 000 people succumbing to the disease in 2016. This figure is expected to shoot up to 880,000 by 2020. ICMR estimated the total number of new cancer cases at around 1.45 million in 2016, and the same is likely to reach 1.73 million by 2020. The situation in this area, therefore, rather grim across the world, including India.

Cancer treatment cost in India is one of the highest in the world:

Anticancer drugs are generally expensive. As stated in a related article, published in the Nature Reviews Clinical Oncology on March 14, 2017, in the United States, a novel anticancer drug routinely costs more than US$ 100,000 per year of treatment. When adjusted for per capita spending power, these lifesaving medicines become most unaffordable in economically developing nations, such as India and China. Not only are their launch prices high and fast rising, but these also often escalate during the respective patent exclusivity period.

That in terms of the ability to pay for drugs, cancer drugs are most affordable in Australia and least affordable in India and China, was established in one of the largest research study presented at the 2016 Annual Meeting of the American Society of Clinical Oncology. Moreover, even in those cases where cancer could be detected early, about half the patients in India are compelled to skip the treatment for high drug cost, highlights another article.

Interestingly, the concerned drug manufacturers seldom, if at all, justify such astronomical drug prices and subsequent price increases well supported by some rational factors, such as, the extent of benefit patients are likely to derive, the novelty of the agents, or detailed spending on research and development, the above paper states.

The increasing trend of price escalation of cancer drugs harms many patients, often directly, through increased out-of-pocket expenses, which reduce levels of patient compliance, or drive thousands of cancer patients skipping the drug treatment, altogether. Consequently, it also harms the society by imposing cumulative price burdens on many patients that are unsustainable.

Despite high cost, annual global spending on anticancer drugs has already exceeded US$100 billion, and is predicted to reach US$150 billion by 2020. In India too, oncology is a leading therapeutic segment, which reached a turnover of Rs. 2,000 Crore (around US$ 320 million) in 2013 and is expected to grow to Rs. 3,831 crore (around US$ 615 million) by the end of 2017, according to a report of Frost and Sullivan.

The reason for high drug price:

The real reason for the high cost of cancer drugs, just as many other life-saving medicines, is quite challenging to fathom. Many attribute its reason to unsustainable R&D models of the global pharma companies, in general.

For example, “the spiraling cost of new drugs mandates a fundamentally different approach to keep lifesaving therapies affordable for cancer patients” – argued an article titled, “How Much Longer Will We Put Up With US$ 100,000 Cancer Drugs?”, published by Elsevier Inc. In the same context, another article titled “Making Cancer Treatment More Affordable”, published in the ‘Rare Disease Report’ on Feb 09, 2017, reiterated that the current R&D model needs to change, as the cost of many such treatments is higher than the cost of an average person’s house in the United States.

Nonetheless, the drug manufacturers answer this difficult question with ease and promptness, citing that the cost of innovation to bring these drugs through a complex research and development (R&D) process to the market, isn’t just very high, but is also increasing at a rapid pace.

Pharma R&D cost:

An analysis by the Tufts Center for the Study of Drug Development, published in the Journal of Health Economics in March, 2016 pegged the average cost to develop and gain marketing approval for a new drug at US$ 2.558 billion. It also said that the total cost of innovation of a new drug and bringing it to market, has increased more than double from US$ 1.22 billion in 2003 to US$ 2.6 billion in 2014. Although these numbers are being vehemently challenged in several credible journals and by the international media, many global pharma majors justify the high new drug prices

by highlighting that developing a new molecule takes an enormous amount of time of 12 to 14 years, lots of financial resources and huge efforts.

On the other hand, an article titled, “Does it really cost US$ 2.6 billion to develop a new drug?”, published in The Washington Post on November 18, 2014 observed that: ‘The never-ending debate about what drugs should cost is in part driven by the fact that no one seems to know what it actually costs to develop one.”

But, why is the decline in the R&D productivity trend?

According to a 2014 review article titled, “Recent Advances in Drug Repositioning for the Discovery of New Anticancer Drugs”, published in the International Journal of Biological Sciences, while the total R&D expenditure for drug discovery worldwide increased 10 times since 1975 (US$ 4 billion) to 2009 (US$ 40 billion), the number of NMEs approved has remained largely flat (26 new drugs approved in 1976 and 27 new drugs approved in 2013). The average time required for drug discovery to market launch has also increased over time in the US and in the EU countries from 9.7 years during 1990s, to 13.9 years from 2000 onwards.

Be that as it may, the bottom-line is regardless of tremendous advancement in biological science, technology and analytics, especially in the new millennium, coupled with increasing investments in pharma R&D, the total number of NMEs that has reached the market hasn’t shown commensurate increase.

One of my articles published in this blog titled, “How Expensive Is Drug Innovation?” found an echo of the same in a globally reputed journal. This study, published by the BMJ on May 2016, titled “Propaganda or the cost of innovation? Challenging the high price of new drugs”, expressed deep concern on the rising prices of new medicines. It reiterated that this trend is set to overwhelm health systems around the world.

Need for an alternative R&D strategy:

The hurdles in discovering and developing new drugs call for alternative approaches, particularly for life threatening diseases, such as cancer. I reckon, it’s about time to scale-up a viable alternative strategy to bring down the R&D cost of new drugs, improve the success rate of clinical development, reduce a decade long ‘mind to market’ timeframe for an innovative drug or a treatment, and of course, the mind blogging cost of the entire process, as asserted in the above report from the Tufts Center.

One such alternative strategy could well be: ‘Drug Repurposing’

Drug Repurposing:

As defined by the National Center for Advancing Translational Sciences, ‘drug repurposing’ “generally refers to studying drugs that are already approved to treat one disease or condition to see if they are safe and effective for treating other diseases”.

As many molecules, with well-documented records on their pharmacology and toxicity profile, have been already formulated and undergone large clinical trials on humans, repurposing those drugs building upon the available documents and experiences for fresh clinical trials in different disease conditions, would hasten the regulatory review process for marketing approval, and at a much lesser cost.

I shall quote here just two such examples of ‘drug repurposing’ from well-known molecules, as follows:

  • Sildenafil (Viagra): The blockbuster drug that was launched by Pfizer in 1998 for the treatment of erectile dysfunctions was originally developed for the treatment of coronary artery disease by the same company in 1980s.
  • Thalidomide: Originally designed and developed by a German pharmaceutical company called Grünenthal in Stolberg as a treatment for morning sickness in 1957, but was withdrawn in 1961 from the market because it caused birth defects. The same molecule was reintroduced in 1998 as a ‘repurposed drug’ to effectively treat patients with erythema nodosum leprosum (ENL) – a complication of leprosy, and multiple myeloma – a type of cancer.

I had given many more examples of ‘drug repurposing’ in one of my earlier articles published in this blog.

Repurposing drugs for cancer:

The above-mentioned review article of International Journal of Biological Sciences 2014 clearly noted: “Drug repositioning has attracted particular attention from the communities engaged in anticancer drug discovery due to the combination of great demand for new anticancer drugs and the availability of a wide variety of cell and target-based screening assays. With the successful clinical introduction of a number of non-cancer drugs for cancer treatment, ‘drug repurposing’ now became a powerful alternative strategy to discover and develop novel anticancer drug candidates from the existing drug space.”

The following are some recent successful examples of ‘drug repurposing’ for anticancer drug discovery from non-cancer drugs, which are mostly under Phase I to II clinical trials:

Drug Original treatment Clinical status for cancer treatment
Itraconazole Fungal infections Phase I and II
Nelfinavir HIV infections Phase I and II
Digoxin Cardiac diseases Phase I and II
Nitroxoline Urinary Tract Infections Preclinical
Riluzole Amyotropic lateral sclerosis Phase I and II
Disulfram Chronic alcoholism Phase I and II

‘Drug repurposing’ market:

A January 2016 report by BCC Research estimates that the global market for drug repurposing will grow from nearly US$ 24.4 billion in 2015 to nearly US$ 31.3 billion by 2020, with a compound annual growth rate (CAGR) of 5.1 percent for the period of 2015-2020.

Expressing concern just not enough:

There are enough examples available across the world regarding stakeholders’ expression of great concern on this issue, with the buzz of such protests getting progressively shriller.

However, in India, high prices of cancer drugs do not seem to be a great issue with the medical profession, just yet, notwithstanding some sporadic steps taken by the National Pharmaceutical Pricing Authority (NPPA) to allay the economic burden of cancer patients to some extent. Encouragingly, the top cancer specialists of the American Society of Clinical Oncology are reportedly working out a framework for rating and selecting cancer drugs not only for their benefits and side effects, but prices as well.

In a 2015 paper, a group of cancer specialists from Mayo Clinic also articulated, that the oft-repeated arguments of price controls stifle innovation are not good enough to justify unusually high prices of cancer drugs. Their solution for this problem includes value-based pricing and NICE like body of the United Kingdom. An interesting video clip from Mayo Clinic justifies the argument.

All this can at best be epitomized as so far so good, and may help increase the public awareness level on this subject. However, the moot point remains: Has anything significantly changed on the ground, on a permanent basis, by mere expression of such concerns?

Conclusion:

This discussion may provoke many to go back to the square number one, making the ongoing raging debate on Innovation, Intellectual Property Rights (IPR) and Public Health Interest to gather more steam, but the core concern continues to remain unresolved.

I hasten to add that all such concerns, including strong protests, may no doubt create some temporary pressure on drug manufacturers, but they are experienced enough to navigate through such issues, as they have been doing, so far. However, for making new cancer drugs cost-effective for a vast population of patients, coming out of the current strategic mold of pharma research and development would be necessary. Grant of Compulsory License (CL), or the expectation of the local drug manufacturers for a Voluntary License (VL) of new cancer drugs, can’t be a routine process either, as it appears unrealistic to me, for various reasons.

I have discussed in this article just one alternative R&D strategy in this area, and that is Drug Repurposing (DR). There could be several others. DR is reportedly gaining increasing focus, as it represents a smart way to exploit new molecular targets of a known non-oncological drug for a new therapeutic applications in oncology. Be that as it may, pharma companies and the academia must agree to sail on the same boat together having a common goal to make new cancer drugs cost-effective for majority of cancer patients struggling hard, for life.

I would conclude this article quoting the President and Chief Science Officer of Illinois-based Cures Within Reach who said: “What I like about drug repurposing is that it can solve two issues: improved health-care impact and reduced health-care cost – That’s a big driver for us.”

Stem Cell Therapy in India: A Potential Game Changer in Disease Treatment

Posted on by
Reply

Stem Cells (SC) offer an incredible potential to instill a new lease of life virtually to any organ of the human body, bringing them back to the pre-disease state through its own biological repair mechanism. Intensive research initiatives are on across the world to harness this unique possibility that will be able to successfully address a plethora of serious and chronic ailments for mankind. The good news is, the global scientific community is taking rapid strides in understanding the complex stem cell biology to give shape to a game changing medical treatment blue print for tomorrow.

Capturing one such pursuit, on February 21, 2017, well-reputed British news daily – ‘The Telegraph’, reported the outcome of a path-breaking medical study for freezing the progression of yet another complex and crippling ailment – Multiple Sclerosis (MS). This research followed a unique SC transplantation process. Intriguingly, both such diseases and the treatment are not generally much talked about, particularly in India. If done, it would increase public awareness and help many patients fetch greater benefits from the available and approved SC therapy in the country. Probably, considering the unfathomable scope of the body’s own repairing toolbox with SC, Prime Minister Narendra Modi reportedly called on Indian biologists to motivate school children for pursuing a career in stem cell research.

Let me now go back for a moment to Multiple Sclerosis (MS) as I am aware of this this disease condition rather closely. One of our close family friends who was a very senior official in one of the top multinational corporations of the world, had to give up his job prematurely being a victim to this serious illness. In that sense, this particular news item rekindles a new hope for many to look for a better quality of life while managing many other diseases of such kind, all over the world, including India.

‘The Telegraph’ reported: in so far, the largest long-term follow-up of SC transplantation treatment study of MS, which was spearheaded by Imperial College London, established that 46 per cent of patients who underwent this treatment did not suffer a worsening of their condition for five years. The treatment works by destroying the immune cells responsible for attacking the nervous system. This is indeed a very significant development in the space of medical research.

This new treatment, called autologous hematopoietic stem cell transplantation (AHSCT), was given to patients with advanced forms of MS who had failed to respond to other medications. However, the researchers noted that the nature of the treatment, which involves aggressive chemotherapy, carried “significant risks”.

It’s worth recapitulating here that MS is caused by the immune system malfunctioning and mistakenly attacking nerve cells in the brain and spinal cord, leading to problems with movement, vision, balance and speech. It’s a lifelong condition and often causes serious disability, with no cure still in sight. The disease is most commonly diagnosed in people in their 20s and 30s, although it can develop at any age.

A new hope with a game changing potential:

The above study of SC transplantation conducted by Imperial College London in MS, is just a recent example, among scores of major steps being taken in this frontier of medical science in preparation of a decisive battle against many more life-threatening and serious debilitating diseases.

No doubt that various treatments involving stem cells are generally considered a novel and rapidly advancing medical technology. However, in a small number of developed countries, such as the United States (US), a number medical procedures with stem cells are being practiced since around last three decades. Bone marrow transplant is the most widely used stem-cell therapy in this area, which was first performed in 1968.

According to California Institute for Regenerative Medicine (CIRM) and various other medical literature, SC treatment has the game changing potential for successful use to:

  • Replace neurons damaged by spinal cord injury, stroke, Alzheimer’s disease, Parkinson’s disease or other neurological problems
  • Produce insulin that could treat people with diabetes and heart muscle cells that could repair damage after a heart attack, or
  • Replace virtually any tissue or organ that is injured or diseased

Thus, stem cells offer limitless possibilities, such as tissue growth of vital organs like liver, pancreas. Today there are many diseases for which no effective treatment still exists, besides giving symptomatic relief, such as Multiple Sclerosis, Parkinson’s disease, Alzheimer’s, severe burn, spinal cord injury. There is a host of other diseases, including several chronic ailments, such as diabetes, heart ailments, rheumatoid arthritis, or some types of cancer, which can’t just be reversed, however, could be managed with a lifelong treatment. For most of these diseases, and several others involving tissue degeneration, SC therapy has the potential to be a huge life and a game changer. It may involve, besides patients, several industries, including pharmaceuticals and biotech sectors.

Major stem cell sources and some key milestones:

Medical scientists and researchers have conclusively established that stem cells are the master cells of any human body. These are undifferentiated cells of the same lineage, retaining the ability to divide throughout life and grow into any one of the body’s more than 200 cell types. Some of the major sources of stem cells in the human body are bone marrow, cord blood, embryonic cells, dental pulp and menstrual blood.

As captured by ‘ExploreStemCells’ of UK, some key events in stem cell research include:

  • 1978: Stem cells were discovered in human cord blood
  • 1981: First in vitro stem cell line developed from mice
  • 1988: Embryonic stem cell lines created from a hamster
  • 1995: First embryonic stem cell line derived from a primate
  • 1997: Cloned lamb from stem cells
  • 1997: Leukemia origin found as hematopoietic stem cell, indicating possible proof of cancer stem cells
  • 1998: University of Wisconsin isolated cells from the inner cell mass of early embryos and developed the first embryonic stem cell lines.
  • 1998: Johns Hopkins University derived germ cells from cells in foetal gonad tissue; pluripotent stem cell lines were developed from both sources.
  • 1999 and 2000: Scientists discovered that manipulating adult mouse tissues could produce different cell types. This meant that cells from bone marrow could produce nerve or liver cells and cells in the brain could also yield other cell types.

All these discoveries were exciting for rapid progress in the field of stem cell research, along with the promise of greater scientific control over stem cell differentiation and proliferation. Currently, many more research studies are underway in globally acclaimed institutions and other boutique laboratories exploring the possibility of wide scale use of SC therapy, even in the treatment of several chronic diseases, including diabetes and heart disorders.

A controversy:

The controversy related to SC research mainly involves Embryonic Stem Cells (ESC) and raises several difficult questions for a speedy resolution. As articulated by the ‘Genetic Science Learning Centre’ of the University of Utah, these are mainly:

  • Does life begin at fertilization, in the womb, or at birth?
  • Is a human embryo equivalent to a human child?
  • Does a human embryo have any rights?
  • Can destruction of a single embryo be justified to provide a cure for a countless number of patients?
  • Since ESC can grow indefinitely in a dish and can, in theory, still grow into a human being, is the embryo really destroyed?

However, in 2006 scientists learned how to stimulate a patient’s own cells to behave like embryonic stem cells. These cells are reducing the need for human embryos in research and revealing exciting new possibilities for stem cell therapies, according to this Centre.

Stem cell research in India:

India has pursued SC research since over a couple decades reasonably supported by the Government, especially the Department of Biotechnology (DBT), besides several remarkable initiatives from the private sector. Ethical guidelines in this regard are also in place, so also are the National Guidelines for Stem Cell Research in India. These guidelines are aimed at obtaining licenses from the Drug Controller General of India (DCGI).

Further, in a major move to regulate and oversee the activities by streamlining SC research in the country, the Government has also set up an Institutional Committee for Stem Cell Research and Therapy (IC-SCRT) and the National Apex Committee for Stem Cell Research and Therapy (NAC-SCRT). This necessitates the researchers on human stem cells, both institutions and the individuals, to be registered with NAC-SCRT through IC-SCRT. To ensure that the concerned companies and individuals follow the National Guidelines, these committees will review, approve and monitor each research project in this area. It now calls for even greater focus from all other stakeholders to help accelerate growth of this niche segment of medical science for patients’ benefits.

SC transplantations using umbilical cord blood and bone marrow for treating neurological, hematological, hepatic and cardiac disorders are being pursued by some well-known medical institutions, such as, AIIMS, PGI Chandigarh, CMC Vellore, AFMC Pune, Manipal Hospital Bangalore. For example, AIIMS, reportedly, undertook a major multi-center trial to look at the role of stem cells in repairing tissue damaged during acute heart attacks, where other treatment process, including a cardiac bypass surgery fails to adequately improve the heart function. Similarly, Shankar Netralaya in Chennai has successfully carried out limbal stem cell transplantations for restoring vision to several patients.

That said, this is a cost intensive area of research, which involves expensive equipment, reagents and other consumables. Moreover, ensuring continuous training for SC researchers and clinicians also poses a major problem. Greater international collaboration in this area, and increasing number of Public-Private-Partnership (PPP) could accelerate the progress of India in this hugely promising area of medical science, reaping a rich harvest for a large patient population of the country.

Stem cell banking:

SC banking is a fast-developing area in this field, especially designed for SC therapy. As not many patients are not currently as much aware or interested in SC therapy as they ought to, it may not appear as an immediate requirement for many. However, an encouraging trend is fast catching up, especially within some enlightened persons, to have in a bank a large reserve of their own or their baby’s stem cells that would be available for any medical emergencies or more effective treatment options, in the future.

It assumes increasing importance because, as we age, illness and the natural process of aging could reduce the number of stem cells available to regenerate organs, muscles and bone. At that time, while treating a serious illness or a grave injury, a person may have fewer adult stem cells that have the collective power to make an effective healing response to SC therapy.

In that context, SC banking provides a great opportunity to store, multiply and utilize a newborn’s or even an adult person’s younger and healthy stem cells for SC therapy during any medical emergency, such as a serious accident or a crippling illness, at a later stage in life.

There are broadly the following two types of SC banking facilities are now available in India:

A. Cord blood stem cell banking:

This is type of SC banking is the process of collecting, processing, cryogenically freezing and preserving the ‘Cord blood’ that remains in the vein of the umbilical cord and placenta at the time of birth, for potential future medical use during SC therapy. Stems cells extracted from the umbilical cord blood have been shown to be more advantageous than those extracted from other sources such as bone marrow. These banked stem cells are considered as a perfect match for the lifetime of the donor baby, and for other family members, as well. This is significant as there exists a greater chance for success in a stem cell transplant between siblings than with unrelated donors and recipients.

B. Adult stem cell banking:

Some state-of-the-art adult stem cell banking services are either already available or in the process of coming up in many places of the world, including India. As an individual’s fat (adipose tissue) is an important source of adult stem cells, with the application of a high precision medical technology of separating, multiplying, and storing adult adipose tissue-derived mesenchymal stem cells for autologous use by physicians, ‘Adult stem cells are stored in these banks.

The good news is, increasing awareness in this area has now started prompting many parents, and also some adults to bank or store their own SC and the baby’s cord blood rich with a specific types of stem cells, that can be utilized, at a later date, in a variety of SC therapy while treating many life-threatening and debilitating diseases, if required.

Types of stem cell therapy:

There are two major types of SC therapies, and both are available in India:

  • Autologous stem cell therapy: uses the adult patient’s own stem cells obtained from the blood, bone marrow.
  • Allogenic stem cell therapy: uses donated stem cells, but faces chances of donor stem cell rejection.

As articulated in the revised stem cell guidelines, stem cells can’t be offered to patients in India as ‘therapy’ unless these are proven effective and safe supported by unequivocal clinical trial data and approved by the DCGI. Otherwise, these can be used only in ‘clinical trials’ as will be approved by the DCGI. The only exception to this is the use of haematopoietic (blood forming) stem cells for treating blood disorders, which is considered as ‘a proven therapy,’ according to available reports.

The Market – Global and India:

September 14, 2015 issue of ‘The Pharma Letter’ stated based on a recent report that the global stem cells market was valued at US$ 26.23 billion in 2013, and is estimated to be worth US$ 119.52 by 2019, registering at a Compounded Annual Growth Rate (CAGR) of 24.2 percent. Whereas, in India, the stem cell market is expected to be around US$ 600 million by 2017. Another report, titled ‘India Stem Cells Market Forecast & Opportunities, 2020’ of ‘Pharmaion’, states that stem cells market in India is expected to grow at a CAGR of over 28 percent during 2015 – 2020.

In terms of services offered, stem cells market in India has been segmented into two main categories, namely SC banking, and SC research. The latter dominated the market in 2014, and is likely to continue its dominance through 2020. Adult stem cells accounted for the majority share in India’s SC market in 2014, as a lot of research being carried out using adult stem cells, besides growing adult stem cell banking and other associated applications in therapeutics.

The major growth drivers for SC market are: increasing patient awareness, an increase in the approval for clinical trials in stem cell research, growing demand for stem cell banking services,

Government support, rising investments in research, and ascending trend of development for regenerative treatment to meet unmet medical needs.

The first stem cell based product approval in India:

On May 30, 2016, a Press Release of ‘Stempeutics Research’ of Bengaluru announced that for the first time in India, DCGI has granted limited approval for manufacturing and marketing of its allogeneic cell therapy product named Stempeucel® for the treatment of Buerger’s Disease – a rare and severe disease condition affecting the blood vessels of the legs, which finally may require amputation. Stempeucel® treatment is designed to enhance the body’s limited capability to restore blood flow in ischemic tissue by reducing inflammation and improving neovascularization. The prevalence of Buerger’s Disease is estimated to be 1,000,000 in India and two per 10,000 persons in the EU and US, as the release stated. Stempeutics Research’ is a company of Manipal Education & Medical Group and a Joint Venture with Cipla Group.

Conclusion:

Research on stem cells, across the world, is taking rapid strides. It has already demonstrated its healing power in changing many human lives either by significantly stalling the progression of several serious ailments, such as Multiple Sclerosis (MS), or reversing the disease conditions, such as serious damage to the heart caused by massive myocardial infarction.

An increasing number of stem cell banks coupled with growing public and private investments in stem cell research, positive narratives are getting scripted for this space in India. With rapidly growing middle class population and comparatively less stringent rules and regulations, India is emerging as a perfect destination for many more global and local stem cell banking companies. Consequently, the stem cell market in the country is expected to witness robust growth in the coming years.

However, only future research on stem cells will be able to unravel whether an Alzheimer’s victim will get back the stolen memory; a cancer patient won’t have to mentally prepare to die of cancer anytime soon, besides spending a fortune towards cancer therapy; an insulin dependent diabetic will no longer require insulin; an individual with damaged heart won’t have to continue with lifelong medication, and it goes on and on.

Nevertheless, if it does… and God willing – it will, ‘Stem Cell Therapy’ would not just be a life changer for many patients, it will be a game changer too for several others, including the pharma, biotech companies and many more within the healthcare sector. If any skeptic still asks, will it really happen? My counter question, in response, will be: Why not?… Why the hell not?

How Cost-Effective Are New Cancer Drugs?

Posted on by
Reply

The main reason why cancer is so serious a disease, is the ability of the malignant cells to spread in the body, both locally by moving into nearby normal tissue, and regionally to nearby lymph nodes, tissues, or organs, affecting even the distant parts of the body. When this happens, doctors term it as metastatic or stage IV (four) cancer.

Although most patients with metastatic tumors would eventually die of cancer, the treatment with various types of anticancer drugs, could help prolong life, in varying degree. No wonder, many new anticancer drugs now obtain regulatory approval based on their effectiveness on metastatic cancer patients. Consequently, it has now become almost a routine to administer newer anticancer drugs to patients with early stage of disease, after they have undergone surgery or radiotherapy.

But, these lifesaving drugs are expensive – very expensive! For example, a newer anticancer treatment is often priced at US$ 100,000 or more per patient, which, obviously, a large majority of the population can’t just afford.

Are these new drugs cost-effective?

To put in simple words, cost effectiveness of a drug is generally ‘expressed in terms of a ratio where the denominator is a gain in health from a measure (years of life, premature births averted, sight-years gained) and the numerator is the cost associated with the health gain.’

From this perspective, a January 2015 research study titled, “Pricing In The Market For Anticancer Drugs”, published by the National Bureau Of Economic Research of the United States observed that anticancer drugs like bevacizumab (US$ 50,000 per treatment episode) and ipilimumab (US$120,000 per episode) have fueled the perception that the launch prices of anticancer drugs are fast increasing over time.

To evaluate the pricing trend of these drugs, the researchers used an original dataset of 58 anticancer drugs, approved between 1995 and 2013, and found that launch-prices, adjusted for inflation and drugs’ survival benefits, increased by 10 percent, or about US$ 8,500, per year. This study was restricted to drugs administered with the primary intent of extending survival time for cancer patients and drugs for which survival benefits have been estimated in trials or modeling studies. The researchers did not consider drugs administered to treat pain or drugs that are administered to alleviate the side effects of cancer treatments.

The paper concluded, as compared to the older ones, newer anticancer treatments, generally, are less cost-effective. Despite this fact, the prices of these drugs are rising faster than their overall effectiveness.

How much do these drugs cost to prolong a year of life for cancer patients?

Another paper, titled “Cancer Drugs Aren’t As Cost-Effective As They Used To Be”, published in the Forbes magazine on September 30, 2015, expressed serious concern on the declining cost-effectiveness of new anticancer drugs. The author termed this trend as unacceptable, and more disturbing when providing just a year of life to cancer patients costs around US$ 350,000 to even US$ 800,000. High prices should reflect large benefits, and we need to demand value out of medical interventions – he recommended.

Do the claims of efficacy also reflect the real-world effectiveness?

Providing an answer to this question, a very recent article titled, “Assessment of Overall Survival, Quality of Life, and Safety Benefits Associated With New Cancer Medicines”, published in the well reputed medical journal ‘JAMA Oncology’ on December 29, 2016, concluded as follows:

“Although innovation in the oncology drug market has contributed to improvements in therapy, the magnitude and dimension of clinical benefits vary widely, and there may be reasons to doubt that claims of efficacy reflect real-world effectiveness exactly.”

As stated above, this conclusion was drawn by the researchers after a detail study on the overall survival, quality of life, and safety benefits of recently licensed cancer medicines, as there was a dearth of evidence on the impact of newly licensed cancer medicines.

The authors analyzed in detail health technology assessment reports of 62 cancer drugs approved in the United States and Europe between 2003 and 2013, and found that these were associated with increased overall survival by an average of 3.43 months between 2003 and 2013. Following is a summary of the detail findings:

  • 43 percent increased overall survival by 3 months or longer
  • 11 percent by less than 3 months
  • 30 percent was not associated with any increase in overall survival, which means almost one third of these drugs lacked evidence to suggest their increased survival rate when compared to alternative treatments
  • Most new cancer drugs, though improved quality of life, were associated with reduced patient safety

The researchers expect this study to support clinical practice, and promote value-based decision-making in the cancer drug treatment, besides assessing their cost-effectiveness.

Some overseas Cancer Institutes protested:

In 2012, doctors at the Memorial Sloan-Kettering Cancer Center reportedly announced through ‘The New York Times’ that their hospital would not be using Zaltrap, a newly patented colorectal cancer drug at that time, from Sanofi. This action of the Sloan-Kettering doctors compelled Sanofi to cut the price of Zaltrap by half.

Unlike India, where prices of even cancer drugs do not seem to be a great issue with the medical profession, just yet, the top cancer specialists of the American Society of Clinical Oncology are reportedly working out a framework for rating and selecting cancer drugs not only for their benefits and side effects, but prices as well.

In a 2015 paper, a group of cancer specialists from Mayo Clinic also articulated, that the oft-repeated arguments of price controls stifle innovation are not good enough to justify unusually high prices of these drugs. Their solution for this problem includes value-based pricing and NICE like body of the United Kingdom.

This Interesting Video from Mayo Clinic justifies the argument.

Was it a tongue-in-cheek action from India?

On March 9, 2012, India did send a signal to global pharma players on its apparent unhappiness of astronomical pricing of patented new cancer drugs in the country. The then Indian Patent Controller General, on that day, issued the first ever Compulsory License (CL) to a domestic drug manufacturer Natco, allowing it to sell a generic equivalent of a kidney cancer treatment drug from Bayer – Nexavar, at a small fraction of the originator’s price.

However, nothing has changed significantly since then on the ground for cancer drugs in the country. Hence, many construe the above action of the Government no more than mere tokenism.

In this context, it won’t be out of place recapitulating an article, published in a global business magazine on December 5, 2013 that quoted Marijn Dekkers, the then CEO of Bayer AG as follows:

“Bayer didn’t develop its cancer drug, Nexavar (sorafenib) for India, but for Western Patients that can afford it.”

Whether, CL is the right approach to resolve allegedly ‘profiteering mindset’ at the cost of human lives, is a different subject of discussion.

VBP concept is gaining ground: 

The concept of ‘Value-Based Pricing (VBP)’, has started gaining ground in the developed markets of the world, prompting the pharmaceutical companies generate requisite ‘health outcome’ data using similar or equivalent products.

Cost of incremental value that a product delivers over the existing ones, is of key significance, and should always be the order of the day. Some independent organizations such as, the National Institute for Health and Clinical Excellence (NICE) in the UK have taken a leading role in this area.

Intriguingly, in India, public health related issues, however pressing these are, still do not seem to arrest much attention of the government to provide significant relief to a large majority of population in the country.

Conclusion:

Warren Buffet – the financial investor of global repute once said, “Price is what you pay. Value is what you get.” Unfortunately, this dictum is not applicable to the consumers of high priced life-saving drugs, such as, for cancer.

Prices of new drugs for the treatment of life-threatening ailments, such as cancer, are increasingly becoming unsustainable, across the world, and more in India. As articulated by the American Society of Clinical Oncology in 2014, this is mainly because their prices are disconnected from the actual therapeutic value of products.

Currently, a sizable number of poor and even middle-income patients, who spend their entire life’s saving for treatment of a disease like cancer, have been virtually priced out of the patented new cancer drugs market.

The plight of such patients is worse in India, and would continue to be so, especially when no trace of Universal Health Care/Coverage (UHC) is currently visible anywhere near the healthcare horizon of the country.

Sharper Focus On Vaccine: A Huge Scope To Reduce Disease Burden In India

Posted on by

Several international research studies have conclusively established that the aggressive application of nationally recommended prevention activities could significantly reduce the burden of disease in several areas. Immunization or vaccination program is one such critical areas.

Several ailments, which used to be so common all over the world, can now be effectively prevented through vaccination. The most common and serious vaccine-preventable diseases are: diphtheria, Haemophilus influenzae serotype b (Hib), hepatitis B and C, measles, meningitis, mumps, pertussis, poliomyelitis, rubella, tetanus, tuberculosis, rotavirus, pneumococcal disease and yellow fever.  The list of the World Health Organization (WHO) indicates that vaccines are now available for 25 different diseases.

Thus, vaccination can save millions of lives and morbidity that such diseases still cause to a very large number of global population. Thanks to vaccines, two most scary diseases – small pox (totally) and polio (almost totally), have been eliminated from the world.

No doubt, why vaccination was voted as one of the four most important developments in medicine of the past 150 years, alongside sanitation, antibiotics and anesthesia by readers of the ‘British Medical Journal (BMJ)’ in 2007. It has been decisively proved that vaccines are one of the most successful and cost-effective public health interventions, which help preventing over 3 million deaths every year, throughout the world, topping the list in terms of lives saved.

In tandem, concerted efforts need to be made by both the industry and the Governments to improve affordable access to all these vaccines for a larger section of the population, especially in the developing world.

A crying need still exists:

Nevertheless, there is still a crying need for greater encouragement, more resource deployment and sharper focus towards newer vaccine development for many more dreaded and difficult diseases. One such area is malaria vaccine.

Some areas of new vaccine development:

Following is an example of some newer therapy areas where novel vaccines are now reportedly under development:

  • Malaria vaccine
  • Cancer vaccine
  • AIDS
  • Alzheimer’s disease

Malaria vaccine:

A July 24, 2015 article of the BBC News states, the ‘European Medicines Agency (EMA)’ gave a positive scientific opinion after assessing the safety and effectiveness of the first anti-malarial vaccine of the world – Mosquirix, developed by the British pharma major GlaxoSmithKline.

The vaccine reportedly targets the ‘P. falciparum’, the most prevalent malaria parasite and the deadlier of the two parasites that transmit the disease. At present, in the absence of any licensed vaccines for malaria, the main preventive measures to contain the spread of this parasitic disease are spraying of insecticides, use of other mosquito repellent and mosquito nets.

However, it was observed during its clinical trial that he best protection with this vaccine was achieved among children aged five to 17 months, receiving three doses of the vaccine a month apart, plus a booster dose at 20 months. In this group, cases of severe malaria were cut by a third over a four-year period, the report said.

Some concern was also expressed, as the effectiveness of the vaccine waned over time, making the booster shot essential, without which the vaccine did not cut the rate of severe malaria over the trial period. Moreover, the vaccine did not prove very effective in protecting young babies from severe malaria.

This caused a dilemma for the ‘World Health Organization (WHO)’. On the one hand, the stark reality of malaria killing around 584,000 people a year worldwide, and on the other, lack of conclusiveness in the overall results for this vaccine. Therefore, the world health body decided at that time to further consider about it, soon after the experts’ deliberation on whether to recommend it for children, among whom trials have yielded mixed results, gets completed.

The good news is, on November 18, 2016, Newsweek reported the announcement of the W.H.O, that Mosquirix will be piloted across sub-Saharan Africa in 2018, after a funding approval of US$ 15 million for this purpose.

Cancer vaccines:

According to the National Cancer Institute, which is a part of the National Institutes of Health (NIH) of the United States, cancer vaccines belong to a class of substances known as biological response modifiers. Biological response modifiers work by stimulating or restoring the immune system’s ability to fight infections and disease. There are two broad types of cancer vaccines:

  • Preventive (or prophylactic) vaccines, which are intended to prevent cancer from developing in healthy people.

-       Persistent infections with high-risk human papillomavirus (HPV) types can cause cervical cancer, anal cancer, oropharyngeal cancer, and vaginal, vulvar, and penile cancers. Three vaccines are approved by the US Food and Drug Administration (FDA) to prevent HPV infection: Gardasil®, Gardasil 9®, and Cervarix®.

-       Chronic Hepatitis B virus (HBV) infection can lead to liver cancer. The FDA has approved multiple vaccines that protect against HBV infection, such as, Engerix-B and Recombivax HB, which protect against HBV infection only.

  • Treatment (or therapeutic) vaccines, which are intended to treat an existing cancer by strengthening the body’s natural immune response against the cancer. Treatment vaccines are a form of immunotherapy.

-       In April 2010, the USFDA approved the first cancer treatment vaccine. This vaccine, sipuleucel-T (Provenge®), is approved for use in some men with metastatic prostate cancer. It is designed to stimulate an immune response to prostatic acid phosphatase (PAP), an antigen that is found on most prostate cancer cells.

Another type of cancer vaccine is currently being developed, known as the Universal Cancer Vaccine.

  • Universal Cancer Vaccine,  June 1, 2016 issue of ‘The Independent’ reported that scientists of Johannes Gutenberg University in Germany have taken a “very positive step” towards creating a universal vaccine against cancer that makes the body’s immune system attack tumors as if they were a virus. The researchers had taken pieces of cancer’s genetic RNA code, put them into tiny nanoparticles of fat and then injected the mixture into the bloodstreams of three patients in the advanced stages of the disease. The patients’ immune systems responded by producing “killer” T-cells designed to attack cancer.

The vaccine was found to be effective in fighting “aggressively growing” tumors in mice. At the same time, such vaccines are fast and inexpensive to produce, and virtually any tumor antigen (a protein attacked by the immune system) can be encoded by RNA, the report said.

The analysts forecast the global cancer vaccines market to grow at a CAGR of 27.24 percent over the period 2014-2019.

HIV/AIDS Vaccine:

The 21st International AIDS Conference (AIDS 2016) held in Durban, South Africa from July 18 to 22, 2016, revealed that a vaccine against HIV will be trialed in South Africa later in 2016, after meeting the criteria needed to prove it, could help fight the epidemic in Africa. A small trial, known as HVTN100, took place in South Africa in 2015 to test the safety and strength of immunity the vaccine could provide, ahead of any large-scale testing in affected populations.

This development reportedly has its origin in a large landmark 2009 trial of RV 144 vaccine in Thailand, demonstrating the proof of concept that a preventive vaccine with a risk reduction of 31 percent could effectively work.  The trial was supported by the World Health Organization (WHO) and UNAIDS. The clinical trial participants who received Vacc-4x, reportedly “experienced a 70 percent viral load decrease relative to their level before starting Anti-Retroviral Therapy (ART), compared with no notable reduction among placebo recipients.”

Alzheimer’s disease vaccine:

A vaccine for Alzheimer’s disease could be trialed in human within the next 3-5 years, after researchers from the United States and Australia have uncovered a formulation that they say successfully targets brain proteins, which play a role in the development and progression of the disease, states a July 18, 2016 report published in the ‘Medical News Today (MNT)’.

This vaccine generates antibodies that target beta-amyloid and tau proteins in the brain – both of which are considered hallmarks of Alzheimer’s disease. In their study, the researchers found that the formulation was effective and well-tolerated in Alzheimer’s mouse models, with no reports of adverse reactions. The vaccine was also able to target the proteins in brain tissue from patients with Alzheimer’s.

Study co-author Prof. Michael Agadjanyan, Institute for Molecular Medicine, California said: “This study suggests that we can immunize patients at the early stages of AD (Alzheimer’s disease), or even healthy people at risk for AD, using our anti-amyloid-beta vaccine, and, if the disease progresses, then vaccinate with another anti-tau vaccine to increase effectiveness.”

If the vaccine continues to show success in these preclinical trials, the researchers envisage that they could be testing the vaccine in individuals at high risk for Alzheimer’s, or those in the early stages of the disease, within the next 3-5 years.

More details on vaccine development:

A 2012 report on vaccines, published by the Pharmaceutical Research and Manufacturers of America (PhRMA) give details of vaccines under development.

Vaccine requirements of the developing world: 

Developing countries of the world are now demanding more of those vaccines, which no longer feature in the immunization schedules of the developed nations. Thus, to supply these vaccines at low cost will be a challenge, especially for the global vaccine manufacturers, unless the low margins get well compensated by high institutional demand.

Issues and challenges:

To produce a safe, effective and marketable vaccine, besides R&D costs, it takes reportedly around 12 to 15 years of painstaking research and development process.

Moreover, one will need to realize that the actual cost of vaccines will always go much beyond their R&D expenses. This is mainly because of dedicated and highly specialized manufacturing facilities required for mass-scale production of vaccines, and then for the distribution of the same mostly using cold-chains.

Around 60 percent of the production costs of vaccines are fixed in nature (National Health Policy Forum. 25. January 2006:14). Thus, such products will need to have a decent market size to be profitable. Unlike many other medications for chronic ailments, which need to be taken for a long duration, vaccines are administered for a limited number of times, restricting their business potential.

Thus, the long lead time required for the ‘mind to market’ process for vaccine development together with high cost involved in their clinical trials/marketing approval process, special bulk/institutional purchase price and limited demand through retail outlets, restrict the research and development initiatives for vaccines, unlike many other pharmaceutical products.

Besides, even the newer vaccines will mostly be required for the diseases of the poor, like Malaria, Tuberculosis, HIV and ‘Non-Communicable Diseases (NCDs)’ in the developing countries, which may not necessarily guarantee a decent return on investments for vaccines, unlike many other newer drugs. Thus, the key issue for developing a right type of newer vaccine will continue to be a matter of pure economics.

India needs a vibrant vaccine business sector:

For a greater focus on all important disease prevention initiatives, there is a need to build a vibrant vaccine business sector in India. To achieve this objective the government should create an enabling ecosystem for the vaccine manufacturers and the academics to work in unison. At the same time, the state funded vaccine R&D centers should be encouraged to concentrate more on the relevant vaccine development projects, ensuring a decent return on their investments for long-term economic sustainability.

Often, these stakeholders find it difficult to deploy sufficient fund to take their vaccine projects successfully through various stages of clinical development to obtain marketing approval from the drug regulator, while earning a decent return on investments. This critical issue needs to be urgently addressed by the Government to make the disease prevention initiatives in the country sustainable.

A possible threat to overcome: 

As per reports, most Indian vaccine manufacturers get a major chunk of their sales revenue from exports to UN agencies, charitable organizations like, the Bill & Melinda Gates Foundation, GAVI, and other country-specific immunization programs.

The report predicts, the virtual monopoly that Indian vaccine manufacturers have enjoyed in these areas, will now be challenged by China, as for the first time in 2012, the Chinese national regulatory authority received ‘pre-qualification’ certification of WHO that allows it to approve locally manufactured vaccines to compete for UN tenders.

Conclusion:

Keeping this in perspective, vaccine related pragmatic policy measures need to be taken in the country for effective disease prevention, covering all recommended age groups, of course, with an equal focus on their effective implementation, without delay. Consequently, this will not only help reduce the disease burden in the country, but also provide the much-awaited growth momentum to the vaccine market in India.

Alongside, increasing number of modern imported vaccines coming in, would help India address one of its key healthcare concerns effectively, and in a holistic way.

It is about time to aggressively garner adequate resources to develop more modern vaccines in the country. In tandem, a rejuvenated thrust to effectively promote and implement vaccine awareness campaigns, would help immensely in the nation’s endeavor for disease prevention with vaccines, that offers a huge scope to reduce disease burden, for a healthier India.

Cancer Care: Dawns A New Era Of Precision Medicine In India

Posted on by
Reply

The concept of ‘Precision Medicine’ has started gaining increasing importance, in the treatment process of many serious diseases, such as cancer. It is now happening in many countries of the world, including India.

The National Institutes of Health (NIH) of the United States, describes ‘Precision Medicine’ as:

“An emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle for each person.”

This is quite in contrast to the widely practiced “one-size-fits-all” type of drug treatment approach, where disease treatment and prevention strategies are developed for the average person, with less consideration for the differences between individuals.

It continues, irrespective of the fact that the same drug doesn’t always work exactly the same way for everyone. It can be difficult for a physician to predict, which patient will benefit from a medication and who won’t, besides having any advance inkling on who will experience Adverse Drug Reactions (ADR) with it, and who will not.

Whereas, the treatment path of ‘Precision Medicine’ allows doctors to predict more accurately which treatment and prevention strategies will work most effectively for a particular disease, and in which groups of people. This is mainly because, ‘Precision Medicine’ looks at the root cause of the ailment for each patient.

For example, in cancer care, use of the term ‘Precision Medicine’ would mean a treatment process for patients with similar tumors, that has been immaculately worked out in accordance with their unique genetic, physical, psychosocial, environmental, and lifestyle factors. Thus, especially for the treatment of life-threatening diseases, a gradual shift from “one-size-fits-all” types of medicines to ‘Precision Medicines”, could bring a new hope of longer survival or remission, for many such patients.

For example, in precision cancer care, it is all about analyzing a patient’s tumor to determine with specificity what drug or combination of drugs will work best with least side effects for that particular individual.

In this article, I shall focus on the development, use and benefits of ‘Precision Medicine’ in cancer, especially in India.

Not a radically new concept:

Several examples of ‘Precision Medicine’ can be found in a few other areas of medicine, as well, though its use in everyday health care is not very widespread, as on date.

One such example can be drawn from the blood transfusion area. A person requiring it, is not given blood from a randomly selected donor. To minimize the risk of any possible post-transfusion related complications, the blood for transfusion is selected only after scientific confirmation that the donor’s blood type matches to the recipient.

Difference between ‘Precision’ and ‘Personalized’ Medicines:

There is a significant overlap between these two terminologies. According to the National Research Council (NRC) of the United States, ‘Personalized Medicine’ is an older term having a meaning similar to ‘Precision medicine’, but may not always be exactly the same.

This change was necessitated as the term ‘Personalized’ could be interpreted to imply that treatments and preventions are being developed uniquely for each individual. Whereas, in ‘Precision Medicine’, the focus is on identifying which approaches will be effective for which patients based on genetic, environmental, and lifestyle factors, as stated above. The NRC, therefore, preferred the term ‘Precision Medicine’ to ‘Personalized Medicine’ to avoid such confusions or misunderstandings. Nevertheless, these two terms are still being used interchangeably.

Another terminology – ‘Pharmacogenomics’ is also used by some, in the same context, which is, in fact, a part of ‘Precision Medicine’. According to National Library of Medicine, United States, Pharmacogenomics is the study of how genes affect a person’s response to particular drugs. This relatively new field combines pharmacology (the science of drugs) and genomics (the study of genes and their functions) to develop effective, safe medications and doses that will be tailored to variations in a person’s genes.

Global initiatives taking off:

Currently, in various parts of the world, there are many initiatives in this area. However, one singular state sponsored initiative, I reckon, is exemplary and stands out.

According to NIH, in early 2015, President Obama announced a research effort focusing on bringing ‘Precision Medicine’ to many aspects of health care. The President’s budget for fiscal year 2016 included US$216 million in funding for the initiative for the NIH, the National Cancer Institute (NCI) – the NIH institute focused on cancer research, and the Food and Drug Administration (FDA).

‘The Precision Medicine Initiative’ has both short-term and long-term goals:

  • The short-term goals involve expanding precision medicine in the area of cancer research. Researchers at the NCI hope to use this approach to find new, more effective treatments for various kinds of cancer based on increased knowledge of the genetics and biology of the disease.
  • The long-term goals focus on bringing ‘Precision Medicine’ to all areas of health and healthcare on a large scale.

The market:

According to a July 2016 research report by Global Market Insights, Inc., the ‘Precision Medicine’ market size was over US$39 billion in 2015, and has been estimated to grow at 10.5 percent CAGR from 2016 to 2023, expanding the market to US$ 87.79 billion by end 2023.

The demand for ‘Precision Medicine’ is expected to significantly increase, specifically in cancer treatments, and also would be driven by advancements in new healthcare technologies, and favorable government regulations, in this area.

Faster US regulatory approval:

According to an August 15, 2016 article, published in the ‘MedCity News’ – a leading online news source for the business of innovation in health care, companion diagnostics, this trend is gaining currency as novel drugs are being paired up with tests that determine which patients will have a higher chance of responding to that drug.

This is vindicated by an expert analysis of a recent study, which found that the probability of a drug approval jumped three-times to 25.9 percent of those drugs that were approved with a predictive biomarker, from 8.4 percent for drugs without one.  This means a threefold increase in success, as determined by FDA registration, if any pharma or biologic drug company had a predictive marker in its new product development strategy. This indication would expectedly encourage more drugs to come with companion diagnostics than without, as the analysis underscored.

The National Institutes of Health (NIH) of the United States defines ‘Biomarkers’ or ‘Biological Markers’ as, “a characteristic that is objectively measured and evaluated as an indicator of normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention.”

‘Precision Medicine’ in India:

In the Indian health care space, ‘Precision Medicine’ is still in its nascent stage. This is despite its need in the country being high, especially while treating life threatening ailments, such as cancer, with greater precision, predictability and, therefore, more effectively than at present.

In several focus group studies too, the local medical specialists have also concurred with the global estimation of the inherent potential of ‘Precision Medicine’, as it rapidly evolves in India, particularly for use in oncology.

Local research:

Studies related to ‘Precision Medicine’ have already commenced, though in a modest scale, in a number of Government research centers, such as, Centre for Cellular and Molecular Biology (CCMB), Indian Council of Medical Research (ICMR), National Institute of Biomedical Genomics (NIBMG) and Institute of Genomics & Integrative Biology (IGIB).

Some large Government Hospitals too, like, All India Institute of Medical Sciences (AIIMS), National Institute of Mental Health and Neurosciences (NIMHANS), and even in Tata Memorial Hospital are making good progress in this area.

Local potential and market impact:

In March 2016, a leading daily of India had reported with examples that oncologists have started using ‘Precision Medicine’, in the country.

In this report, a molecular geneticist was quoted saying, “We see patients with blood, breast, lung, and colon cancer being referred for genetic testing on a routine basis. This testing is either for predictive purposes or for precision medicine guidance, where genetic tests are increasingly being used to determine which drug may be used for treatment.”

“We have had more than a few cases where patients respond well after being put on a new drug based on the results of these tests,” the expert said.

According to a May 2016 report of the Indian Council of Medical Research (ICMR), in the year 2016, the total number of new cancer cases is expected to be around 14.5 lakh (1.5 million), and the figure is likely to reach nearly 17.3 lakh (1.7 million) of new cases in 2020.

Over 7.36 lakh (736,000) people are expected to succumb to this disease in 2016 while the figure is estimated to shoot up to 8.8 lakh (880,000) by 2020. The data also revealed that only 12.5 percent of patients come for treatment in early stages of the disease.

Taking note of this fast ascending trend, it would be quite reasonable to expect that treatment with ‘Precision Medicine’, using advanced genetic profiling, would catch up, and grow proportionally in some section of the population, sooner than later. This trend is expected to keep pace with the commensurate increase in the anti-cancer drug market of India.

In tandem, the demand for preventive measures, especially, for cancer, cardiovascular, psychosomatic and many chronic metabolic diseases at the onset or prior to even onset stages, based on genome-based diagnostics, are also expected to go north. This would primarily be driven by increasing health awareness of the younger generation of India.

The spin-off commercial benefits for the pharma and diagnostic players in India, competing in these segments, could well be a significant boost even in the market potential of the older generic drugs in new patient groups, prompted by many out-of- box diagnostic and disease treatment strategies.

Another interesting article on genomic diagnostics for ‘Precision Medicine’, published on March 15, 2016 by ‘Pistoia Alliance’ – a global, not-for-profit alliance in life science that aims at lowering barriers to innovation in R&D, also expressed similar views regarding the future potential of ‘Precision Medicine’ in India.

Some key strategic steps:

Taking proactively some key strategic steps for business planning and development by the domestic pharma and diagnostic players, is now more important than ever before. This may call for developing some critical studies that would accelerate working out novel strategies for ‘Precision Medicine’ in India, besides obtaining required regulatory approvals in the coming years. The studies may include, among others:

  • Detailed analysis of target patient populations
  • Their genetic makeup for different types, or sub-types of diseases
  • Addressable sub populations
  • Their current treatment strategies, costs, affordability and differentiated value offerings of each, if any.

Conclusion:

Genomic research in India is now mainly directed towards routine genome-based diagnostics for a number of conditions, mostly for cancer. The country needs to encourage taking rapid strides to first sharpen and then gradually broaden this area, in various ways, for more effective and predictable treatment outcomes with ‘Precision Medicine’. As on date, most of such studies are carried out in the United States and Europe.

Alongside, a robust regulatory framework is required to be put in place, for wider usage of ‘Precision Medicine’ in India, without causing any concern to stakeholders. Government should also explore the need of clearly defining, and putting in place transparent, patient-friendly and robust Intellectual Property (IP) policies in the ‘Precision Medicine’ related areas to encourage innovation.

Healthcare expenditure being out-of-pocket for a vast majority of the population in India, the additional cost to be incurred for genomic sequencing tests, still remains a huge concern for many. Nevertheless, the good news is, many players have now gradually started entering into this area, spurring a healthy competition. This process would also gain accelerated momentum, as we move on.

This is just a dawn of a new era of ‘Precision Medicine’ in India. Its rapid development, is expected to be driven by a large number of startups, equipped with state-of-art technology, and hopefully, with greater health insurance penetration and the support from the Government. All this would bring the ‘Precision Medicine’ treatment cost affordable to a sizeable section of the population in the country, particularly for the treatment of cancer. The evolving scenario appears to be a win-win one, both for the patients, as well as the pharma and diagnostic players in India.
