Improving Patient Access To Biosimilar Drugs: Two Key Barriers

Posted on by
Reply

Novel biologic medicines have unlocked a new frontier offering more effective treatment for a host of chronic and life-threatening diseases, such as varieties of cancer, rheumatoid arthritis and diabetes, to name just a few. However, these drugs being hugely expensive, many patients do not have any access, or adequate access, to them. According to the Biosimilar Council of GPhA, only 50 percent of severe Rheumatoid Arthritis patients receive biologic medicines, even in the United States, Europe and Japan, leave aside India.

Realizing the gravity of this situation, a need to develop high quality, reasonably affordable and similar to original biologic brands, was felt about ten years ago. These were intended to be launched immediately after patent expiry of the original biologic. Such medicines are termed as biosimilar drugs. It is worth noting, even biosimilar drug development involves complex manufacturing processes and handling, while dealing with derivatives of highly sensitive living organisms.

The regulatory approval process of these drugs is also very stringent, which demands robust clinical data, demonstrating high similarity, both in effectiveness and safety profile, to original biologic brands, known as the reference product. The clinical data requirements for all new biosimilars include data on patients switching from the originator’s brand, and also between other biosimilars. Clinical evidences such as these, are expected to provide enough confidence to physicians for use of these products.

An article published in the PharmaTimes magazine in January 2016, reiterated that over the last couple of years, a wealth of supporting data has been published in medical journals and presented at global congresses, including real-world data of patients who have been switched to the new drug from the originator. This has led to a positive change in physician and patient attitudes towards biosimilars.

The good news is, besides many other regulated markets, as of May 2017, five biosimilar drugs have been approved even by the US-FDA, and several others are in the pipeline of its approval process.

That said, in this article I shall mainly focus on the two key barriers for improving patient access to biosimilar drugs, as I see it.

Two major barriers and their impact:

As I see it, there appear to be the following two key barriers for more affordable biosimilar drugs coming into the market, improving patients’ access to these important biologic medicines:

  • The first barrier involves fierce legal resistance from the original biologic manufacturers of the world, on various grounds, resisting entry of biosimilar varieties of their respective brands. This compels the biosimilar drug manufacturers incurring heavy expenditure on litigation, adding avoidable cost. A glimpse of this saga, we are ‘privy’ to witness even in India, while following Roche versus Biocon and Mylan case related to ‘Trastuzumab’. This barrier is one of the most basic types, that delays biosimilar drug entry depriving many new patients to have access to lower priced effective biologic for the treatment of serious diseases.
  • The other major barrier that exists today, involves ‘interchangeability’ of original biologic with biosimilar drugs. It simple means that in addition to being highly similar, a biosimilar drug manufacturer would require producing indisputable clinical evidence that it gives the same result for any given patient just as the original biologic. We shall discuss the reason behind this regulatory requirement later in this article. However, this is an expensive process, and the absence of it creates a barrier, making the physicians hesitant to switch all those existing patients who are on expensive original biologic drugs with less expensive available biosimilar alternatives.

The first or the initial barrier:

The first or the initial barrier predominantly involves patent related legal disputes, that can only be settled in a court of law and after incurring heavy expenditure towards litigation. Provided, of course, the dispute is not mutually resolved, or the law makers do not amend the law.

An interesting case in India:

Interestingly, in India, a similar dispute has knocked the doors of both the high court and the Competition Commission of India (CCI). From a common man’s perspective, it appears to me that the laws under which these two institutions will approach this specific issue are seemingly conflicting in nature. This is because, while the patent law encourages no market competition or a monopoly situation for a patented product, competition law encourages more market competition among all related products. Nonetheless, in this specific case CCI is reportedly investigating on the alleged ‘abuse of the regulatory process’, as it has opined ‘abuse of regulatory process can constitute an abuse of dominance under the (CCI) Act.’                                                                                            

The second barrier:

I am not going to discuss in this article the relevance of this barrier, in detail. Nevertheless, this one is also apparently equally tough to comply with. The very fact that none out of five biosimilar drugs approved in the United States, so far, has been considered ‘interchangeable’ by the US-FDA, vindicates the point.

That this specific regulatory demand is tough to comply with, is quite understandable from the requirements of the US-FDA in this regard, which goes as follows:

“To support a demonstration of interchangeability, the data and information submitted to FDA must show that a proposed interchangeable product is biosimilar to the reference product and that it can be expected to produce the same clinical results as the reference product in any given patient. Also, for products that will be administered more than once, the data and information must show that switching a patient back and forth between the reference product and the proposed interchangeable product presents no greater risk to the patient in terms of safety or diminished efficacy when compared to treating them with the reference product continuously.”

The reasoning of innovative biologic drug makers:

On this subject, the stand taken by different innovative drug makers is the same. To illustrate the point, let me quote just one of them. It basically sates, while biosimilar drugs are highly similar to the original medicine, the patient’s immune system may react differently due to slight differences between the two medicines when they are alternated or switched multiple times. This phenomenon, known as immunogenicity, is not a common occurrence, though. But there have been rare instances when very small differences between biologic medicines have caused immune system reactions that changed the way a medicine was metabolized, or reduced its effectiveness.

It further reiterates, the US-FDA requirements to establish ‘interchangeability’ between a biosimilar drug and the original one, or between biosimilars may seem like nuances, but are important because ‘interchangeability’ allows pharmacists to substitute biosimilars without consulting the doctor or patient first.

It may, therefore, indicate to many that innovative biologic drug manufacturers won’t want substitution of their expensive biologic with more affordable biosimilar drugs, on the ground of patient safety issues related to immunogenicity, though its instances are rather uncommon.

Some key players in biosimilar drug development:

Having deliberated on the core subject of this article, let me now very briefly name the major players in biosimilar drug development, both in the developed world, and also in India.

The first biosimilar drug was approved by the US-FDA in 2006, and the product was Omnitrope (somatropin) of Novartis (Sandoz). It was the same in the European Union (EU), as well. Subsequently, many other companies reportedly expressed interest in this field, across the globe, including Pfizer, Merck, Johnson and Johnson, Amgen, AbbVie, Hospira, AstraZeneca and Teva, among many others.

Similarly, in India, the major players in this field include, Biocon, Sun Pharma, Shantha Biotech, Dr. Reddy’s Lab, Zydus Cadila, Panacea Biotech and Reliance Life Sciences.

As featured on the Amgen website, given the complexity and cost of development and manufacturing, biosimilars are expected to be more affordable therapeutic options, but are not expected to generate the same level of cost savings as generics. This is because, a biosimilar will cost US$100 to US$200 million and take eight to ten years to develop. Whereas, a small molecule generic will cost US$1 to US$5 million and take three to five years to develop.

The market:

According to the 2017 report titled “Biosimilar Market: Global Industry Analysis, Trends, Market Size & Forecasts to 2023” of Research and Markets, the market size of the global biosimilar market was valued over US$ 2.5 billion during 2014, and it surpassed US$ 3.30 billion during 2016. The global biosimilar market is projected to surpass US$ 10.50 billion by 2023, growing with a CAGR between 25.0 percent and 26.0 percent from 2017 to 2023.

According to this report, gradually increasing awareness, doctors’ confidence and the lower drug cost are expected to boost the demand and drive the growth of the global biosimilar market during the forecast period. Segments related to diabetes medicine and oncology are expected to attain faster growth during the forecast period. Patent expiry of several blockbuster drugs is a major basic factor for growth of the global biosimilar market, as it may encourage the smaller manufacturers to consider producing such biologic drugs in those segments.

Conclusion:

Biosimilar drugs are expected to benefit especially many of those patients who can’t afford high cost biologic medicines offering better treatment outcomes than conventional drugs, in the longer term. These drugs are now being used to effectively manage and treat many chronic and life-threatening illnesses, such cardiac conditions, diabetes, rheumatoid arthritis, psoriasis, multiple sclerosis, Crohn’s disease, HIV/AIDS and cancer.

However, improving patient access to high quality biosimilar drugs, at an affordable price, with increasing competition, could be a challenge, as two key barriers are envisaged to attain this goal. Overcoming these meaningfully, I reckon, will involve choosing thoughtfully a middle path, creating a win-win situation, both for the patients, as well as the industry.

Adequate competition in the biologic drug market is essential – not only among high-priced original biologic brands and biosimilars, but also between biosimilar drugs. This is so important to increase patient access to biologic drugs, in general, across the world, including India.

The current situation demands a sense of urgency in searching for a middle path, which may be created either through a legal framework, or any other effective means as would deem fair and appropriate, without compromising with patient safety, at least, from where it is today.

Rebuilding Pharma Image: A Laudable Mindset – Lacking In Many

Posted on by

The fierce debate on ethics and compliance related issues in the pharma marketing practices still reverberates, across the globe. One of its key fallout has been ever-increasing negative consumer perception about this sector, sparing a very few companies, if at all. As a result, many key communications of the individual players, including the industry associations specifically targeted to them, are becoming less and less credible, if not ineffective.

Which is why, though pharma as an industry is innovative in offering new medicines, consumers don’t perceive it so. Despite several drug players’ taking important steps towards stakeholder engagement, consumers don’t perceive so. The list goes on and on. I discussed on such consumer perception in my article of June 26, 2017. Hence, won’t further go into that subject, here.

General allegation on the pharma industry continues to remain unchanged, such as the drug industry tries to influence the medical profession, irrespective of whether they write prescription drugs for patients or are engaged in regulatory trial related activities aimed at product marketing.

Let me give an example to illustrate the later part of it, and in the Indian context. On April 26, 2017, it was reported that responding to a joint complaint filed by Mylan and Biocon in 2016, alleging that the Roche Group indulged in “abusive conduct”, the Competition Commission of India (CCI) gave directions for carrying out a detailed investigation on the subject. This probe was initiated to ascertain, whether Roche used its dominant position to maintain its monopoly over the breast cancer drug Trastuzumab, adversely impacting its access to many patients.

Such a scenario, though, undoubtedly disturbing, is very much avoidable. Thus, winning back the fading trust of the consumers in the industry, should be ticked as a top priority by the concerned parties.

In this article, I shall mostly focus on some recent developments related to ethics and compliance issues, mainly in pharma marketing, and with a small overlap on the regulatory and other areas, as and when required to drive home a point.

It shakes the trust base on the medical profession too:

This menace, as it were, though, more intense in India, is neither confined to its shores alone, nor just to the pharma industry, notwithstanding several constituents of big pharma have been implicated in mega bribery scandals in different countries. There doesn’t seem to be much doubt, either, that its impact has apparently shaken the very base of trust even on the medical profession, in general.

Not very long ago, Dr. Samiran Nundy, while holding the positions of Chairman, Department of Surgical Gastroenterology and Organ Transplantation at Sir Ganga Ram Hospital and Editor-in-Chief of the Journal of Current Medicine Research and Practice, reportedly exposed the widespread malpractices of the doctors in India who are taking cuts for referrals and prescribing unnecessary drugs, investigations and procedures for profit.

This practice continues even today, unabated. On June 18, 2017, it was widely reported in India that Maharashtra Government has decided to form a 3-member committee for suggesting effective ways to check the ‘cut practice’ of doctors. This decision followed a public awareness campaign on this subject, initiated by well-reputed late heart surgeon – Dr. Ramakanta Panda’s Asian Heart Institute, located in Mumbai. The hospital had put up a hoarding saying: ‘No commission. Only honest medical opinion’. The Indian Medical Association opposed the hoarding. But the hospital wrote to Maharashtra medical education minister seeking a legislation to fight this malpractice.

To contain this malady across India, for the sake of patients, Dr. Nundy had then suggested that to begin with, “The Medical Council of India (MCI), currently an exclusive club of doctors, has to be reconstituted. Half the members must be lay people like teachers, social workers and patient groups like the General Medical Council in Britain, where, if a doctor is found to be corrupt, he is booted out by the council.”

This subject continues to remain an open secret, just as pharma marketing malpractices, and remains mostly confined to the formation of various committees.

“Corruption ruins the doctor-patient relationship in India” – a reconfirmation:

“Corruption ruins the doctor-patient relationship in India” - highlighted an article published in the British Medical Journal (BMJ) on 08 May 2014. Its author – David Berger wrote, “Kickbacks and bribes oil every part of the country’s health care machinery and if India’s authorities cannot make improvements, international agencies should act.”

He reiterated, it’s a common complaint, both of the poor and the middle class, that they don’t trust their doctors from the core of hearts. They don’t consider them honest, and live in fear of having no other choice but to consult them, which results in high levels of doctor shopping. David Berger also deliberated on the widespread corruption in the pharmaceutical industry, with doctors bribed to make them prescribe specified drugs.

The article does not fail to mention that many Indian doctors do have huge expertise, are honorable and treat their patients well. However, as a group, doctors generally have a poor reputation.

Until the medical profession together with the pharma industry is prepared to tackle this malady head-on and acknowledge the corrosive effects of medical corruption, the doctor-patient relationship will continue to lie in tatters, the paper says.

Uniform code of ethical pharma marketing practices:

This brings us to the need of a uniform code of ethical pharma marketing practices. Such codes, regardless of whether voluntary or mandatory, are developed to ensure that pharma companies, either individually or collectively, indulge in ethical marketing practices, comply with all related rules and regulations, avoid predominantly self-serving goals and conflict interest with the medical profession, having an adverse impact on patients’ health interest.

This need was felt long ago. Accordingly, various pharma companies, including their trade associations, came up with their own versions of the same, for voluntary practice. As I wrote before, such codes of voluntary practice, mostly are not working. That hefty fines are being levied by the government agencies in various countries, that include who’s who of the drug industry around the world, with India being a major exception in this area, would vindicate the point.

Amid all these, probably a solitary global example of demonstrable success with the implementation of voluntary codes of ethical pharma marketing practices, framed by a trade association in a major western country of the world, now stands head and shoulders above others.

Standing head and shoulders above others:

On June 23, 2017, the international business daily – ‘Financial Times’ (FT), reported: “Drug maker Astellas sanctioned for ‘shocking’ patient safety failures”

Following ‘a series of shocking breaches of guidelines’ framed by ‘The Prescription Medicines Code of Practice Authority (PMCPA)’ – an integral part of the ‘Association of the British Pharmaceutical Industry (ABPI)’, publicly threatened the Japanese drug major – Astellas, for a permanent expulsion from the membership of the Association. However, PMCPA ultimately decided to limit the punishment to a 12-month suspension, after the company accepted its rulings and pledged to make the necessary changes. Nevertheless, Astellas could still be expelled, if PMCPA re-audit in October do not show any “significant progress” in the flagged areas – the report clarified.

Interestingly, just in June last year, ABPI had suspended Astellas for 12 months ‘because of breaches related to an advisory board meeting and deception, including providing false information to PMCPA’. The company had also failed to provide complete prescribing information for several medicines, as required by the code – another report highlights.

Astellas is one of the world’s top 20 pharmaceutical companies by revenue with a market capitalization of more than £20bn. In 2016 its operations in Europe, the Middle East and Africa generated revenues of €2.5bn –reports the FT.

What is PMCPA?

One may be interested to fathom how seriously the implementation of the uniform code of pharmaceutical marketing practice is taken in the United Kingdom (UK), and how transparent the system is.

The Prescription Medicines Code of Practice Authority (PMCPA) is the self-regulatory body which administers the Association of the British Pharmaceutical Industry’s (ABPI) Code of Practice for the Pharmaceutical Industry, independent of the ABPI. It is a not-for-profit body, which was established by the ABPI on 1 January 1993. In other words, the PMCPA is a division of the British pharma trade association – ABPI.

According to PMCPA website, it:

  • Operates the complaints procedure under which the materials and activities of pharmaceutical companies are considered in relation to the requirements of the Code.
  • Provides advice and guidance on the Code.
  • Provides training on the Code.
  • Arranges conciliation between pharmaceutical companies when requested to do so.
  • Scrutinizes samples of advertisements and meetings to check their compliance with the Code.

As I often quote: ‘proof of the pudding is in eating’, it may not be very difficult to ascertain, how a constructive collective mindset of those who are on the governing board of a pharma trade association, can help re-creating the right image for the pharma industry, in a meaningful way.

Advertisements and public reprimands for code violations:

The PMCPA apparently follows a system to advertise in the medical and pharmaceutical press brief details of all cases where companies are ruled in breach of the Code. The concerned companies are required to issue a corrective statement or are the subject of a public reprimand.

For the current year, the PMCPA website has featured the details of three ABPI members as on May 2017, namely, Gedeon Richter, Astellas, and Gedeon Richter, for breaching the ethical code of practices.

However, in 2016, as many as 15 ABPI members featured in this list of similar violations. These are:  Vifor Pharma, Celgene, Takeda, Pierre Fabre, Grünenthal Ltd, Boehringer Ingelheim Limited, Eli Lilly, AstraZeneca, Janssen-Cilag, Astellas, Stirling Anglian, Guerbet, Napp, Hospira, Genzyme, Bausch & Lomb and Merck Serono. It is worth noting that the names of some these major companies had appeared more than once, during that year.

I am quoting the names of those companies breaching the ABPI code, just to illustrate the level of transparency in this process. The details of previous years are available at the same website. As I said, this is probably a solitary example of demonstrable success with the implementation of voluntary practices of ethical pharma marketing codes, framed by any pharma trade association.

In conclusion:

Many international pharmaceutical trade associations, which are primarily the lobbying outfits, are known as the strong votaries of self-regulations of the uniform code of ethical pharma marketing practices, including in India. Some of them are also displaying these codes in their respective websites. However, regardless of all this, the ground reality is, the much-charted path of the well-hyped self-regulation by the industry to stop this malaise, is not working. ABPI’s case, I reckon, though laudable, may well be treated as an exception. 

In India, even the Government in power today knows it and publicly admitted the same. None other than the secretary of the Department of pharmaceuticals reportedly accepted this fact with the following words: “A voluntary code has been in place for the last few months. However, we found it very difficult to enforce it as a voluntary code. Hence, the government is planning to make it compulsory.”

Following this, as reported on March 15, 2016, in a written reply to the Lok Sabha, the Minister of State for Chemicals and Fertilizers, categorically said that the Government has decided to make the Uniform Code of Pharmaceutical Marketing Practice (UCPMP) mandatory to control unethical practices in the pharma industry.

The mindset that ABPI has demonstrated on voluntary implementation of their own version of UCPMP, is apparently lacking in India. Thus, to rebuild the pharma industry image in the country and winning back the trust of the society, the mandatory UCPMP with a robust enforcement machinery, I reckon, is necessary – without any further delay.

However, the sequence of events in the past on the same, trigger a critical doubt: Has the mandatory UCPMP slipped through the crack created by the self-serving interest of pharma lobbyists, including all those peripheral players whose business interests revolve round the current pharma marketing practices. Who knows?

Nonetheless, the bottom line remains: the mandatory UCPMP is yet to be enforced in India… if at all!

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 ‘National Policy For Rare Diseases’ More Meaningful With ‘Orphan Drugs Act’

Posted on by

In November 2016, while hearing a related case, the Delhi High Court reportedly directed the Union Government to finalize and implement a policy on rare diseases, with a provision for free treatment with the expensive medications, as will be required by patients.

Earlier in 2014, while passing the judgement in response to a petition filed by a seven-year-old son of a rickshaw puller seeking affordable treatment for the rare disease that he is suffering from, the Delhi High Court concluded that, “every person has a fundamental right to quality health care that is affordable, accessible and compassionate.”

Currently, the treatment for rare diseases costs the patients an arm and a leg, ranging between Rs. 40 lakhs (US$ 62,000 approx.) to Rs 1.70 crores (US$ 267,000 approx.), which is way beyond the reach of most Indians.

Subsequently, on May 26, 2017, the Ministry of Health and Family Welfare filed an affidavit before the honorable Court, submitting a copy of the National Policy for Rare Diseases 2017, stating that it will aim to facilitate effective diagnosis and affordable treatment. This development is indeed good news, especially considering around 6 to 8 percent of the world population suffer from ‘rare diseases’, and India is no exception.

The key highlights of the new policy:

As per available information, following are the 10 major highlights of the National Policy for Rare Diseases 2017:

  • The Union Government to create a corpus with an initial funding of Rs 100 crores (US$ 16 million). The State Governments would also provide for a similar fund with a 60 percent contribution from the Centre. This corpus is primarily for the treatment of genetic disorders, excluding rare blood diseases, such as, thalassemia and sickle-cell anemia.
  • For the sustainability of the corpus, Public Sector Units and Corporates will be encouraged for the contribution in these earmarked funds, as part of their corporate social responsibility.
  • Appropriate institutions will be accredited by the government for diagnosis and treatment of rare diseases.
  • To ensure adequate availability and reasonable affordability of the drugs for rare diseases, the Drug Controller General of India (DCGI) will consider amending the Drug and Cosmetics Act with requisite provisions to make clinical trials and import of ERTs possible.
  • The Department of Financial Services to ensure coverage of rare diseases under insurance schemes.
  • Employees State Insurance Corporation (ESIC) will explore whether the ceiling limit of funding the treatments for rare diseases can be increased through suitable amendments.
  • The policy recognizes that rare diseases are, in most cases, serious, chronic, debilitating and life-threatening, often requiring long – specialized treatments, and may also lead to some form of handicap, at times extremely severe in nature.
  • About 50 percent of new cases of rare diseases are in children and responsible for 35 percent of deaths before the age of one, 10 percent between the ages of one, and five years and 12 percent between five and 15 years.
  • As a preventive measure, the policy may consider the feasibility of providing pre-conception and ante-natal genetic counselling and screening programs for diagnosing genetic disorders, which would provide a choice to parents about giving birth to children with genetic disorders, especially for families that have a diagnosed genetic disorder, or a high risk profile for it.
  • The policy gives Indian Council for Medical Research (ICMR) the responsibility of creating a patient registry, as India has no epidemiological data on rare diseases.

Rare diseases – definition:

There is no universal definition of rare diseases. For example, while the US defines a rare disease as one that affects less than 200,000 people nationwide, in China, this number changes to 1 in 500,000 people (or neonatal morbidity of less than 1 in 10,000). India doesn’t yet have a clear definition for the same – not even in its new policy for rare diseases.

However, according to Rare Diseases India (RDI) – a foundation for research on rare diseases and disorders, any disease having fewer than 100 patients per 100,000 population fall into this category. Whereas, those ones affecting 2 patients per 100,000 population are described as ultra-rare diseases.

Rare Diseases in India:

The Organization for Rare Diseases in India (ORD), states that 1 in 20 Indians is affected by such diseases. About 6000 to 8000 rare diseases, mostly genetic in nature, have been identified in India. It was initially estimated that over 31 million Indians are suffering from such disorders in the country, many of which still do not have any cure. Moreover, epidemiological data for most of these ailments is hardly available.

To increase awareness for rare diseases, Rare Diseases Day was observed for the first time in India (New Delhi) on February 28, 2010.

Orphan diseases and orphan drugs:

According to RDI, rare diseases are often referred to as ‘orphan’ diseases. Consequently, the drugs that are specifically developed to treat ‘orphan’ or ‘rare disease conditions’ are called ‘orphan drugs’. The reason being, pharma companies do not generally take such drugs through further stages of development for market launch, or in other words, these are orphaned for economic considerations, though are important to save many precious lives.

Need to encourage orphan drug development in India:

According to SanOrphan SA, Geneva, Switzerland, around 65 percent of rare diseases is serious and disabling. Interestingly, about 250 new rare diseases are discovered each year, corresponding to five new rare diseases per week. As the scenario is no different in India, it prompts the need to encourage development of effective and affordable orphan drugs in the country.

However, without appropriate ecosystem being in place, developing an orphan drug in India, specifically to treat a very small number of such patient populations, through a cost intensive R&D initiative with a low potential of return on investments, is indeed a challenging proposition for many pharma players. Although, in the western world, this trend has started changing now, driven by various other commercial reasons.

Why should ‘Orphan Drugs Act’ follow the National Policy on rare diseases?

National Policy for Rare Diseases is undoubtedly a good beginning, though was brought under the directive of Delhi High Court. Nevertheless, to encourage ‘Orphan Drugs’ development within the country, a robust ‘Orphan Drugs Act’ should now logically follow.

One may well ask, why is this Act is so necessary in India? This is because, the new ‘National Policy for Rare Diseases’ charts just the pathway of a course of action that the Government is planning to take in this area. Policies, as we know, though, are a set of well-articulated intents, do not guarantee that these will be successfully followed to achieve the pre-set long-term goals. Whereas, all legislative Acts or duly enacted laws, are legally enforceable. It is worth noting, while the national policies can be formulated by the government, an Act must be passed by the lawmakers in the Parliament.

Consequently, it is now a well-accepted fact that ‘Orphan Drugs Act’ encourages development of drugs for rare diseases. In an article titled, “What the Orphan Drug Act has done lately for children with rare diseases: a 10-year analysis”, published by the National Center for Biotechnology Information (NCBI), U.S, National Library of Medicine, the authors highlighted that in the U.S. 1138 orphan drugs were designated and 148 received marketing approval, of which 38 (26 percent) were for pediatric diseases, from 2000 to 2009. The percentage of approvals for pediatric products increased from 17.5 (10 of 57) in the first half of the decade, as compared to 30.8 (28 of 91) in the second half. Based on these data, the paper concluded that the incentives provided in the ‘Orphan Drugs Act (ODA)’ of the United States of America, have led to increased availability of specific drugs for the treatment of ‘Rare Diseases’ in the country.

Other countries did – why not India?

1983 signaled the importance of ‘Orphan Drugs’ with the ‘Orphan Drugs Act (ODA) in the U.S.A. A decade after, in 1993, Japan took similar initiative followed by Australia in 1999. Currently, Singapore, South Korea, Canada and New Zealand are also having their country specific ODAs.

Following similar footsteps, India should also encourage its domestic pharmaceutical industry to get engaged in research to discover drugs for rare diseases by putting an ‘Orphan Drugs Act’ in place, extending financial support, tax exemptions and regulatory concessions like smaller and shorter clinical trials, among several other areas, without delay.

Opportunities galore:

The above constraints in the development of orphan drugs have now been turned into an opportunity galore by the global pharma industry, where the domestic players should not lag much behind. Orphan drugs, backed by adequate financial incentives provided by laws in different countries, are now seen as a research and development priority to significantly boost the top and the bottom-line of pharma business.

As IgeaHub has highlighted, orphan drugs, though, cater to a small patient pool, the remunerative price of these drugs offsets the commercial challenges, as mentioned earlier. For example, in 2010, Soliris, which treats paroxysmal nocturnal hemoglobinuria (PNH) that affects 1 out of 500,000, was considered as the industry’s most expensive drug amounting to US$ 409,000 per year of treatment, which generated a total of US$ 541 million revenue for Alexion Pharmaceuticals in that year. In 2012, Soliris recorded a sales turnover of US$ 1.13 billion, which is expected to cross the mark of US$ 3.40 billion in 2018. Further, in 2012, the top selling orphan drug in the USA – Rituxan of Roche – used for the treatment of chronic lymphocytic leukemia, generated US$ 7.15 billion in total sales. Post patent expiry, in 2018, the same drug is expected to yield a revenue of US$ 6.99 billion.

The market:

Evaluate Pharma’s Orphan Drug Report 2017 estimates the worldwide Orphan Drug Sales of total US$ 209 billion, with CAGR of +11 percent for 2017 to 2022 period, which is double of the overall prescription Market Growth. Excluding generics orphan drugs are set to contribute 21.4 percent of Worldwide Prescription Sales by 2022.

Big pharma dominates this segment. Seven of the top 10 companies’ orphan drug sales are from global industry players, who have won approval for their biggest products in various niche indications.

Other commercial benefits:

Thomson Reuters reported additional commercial opportunities with an appropriate ODA, which in the United States are as follows:

  • 15 percent of the ‘Orphan Drugs’ analyzed by them had subsequent launches for other rare illnesses.
  • 6 out of the top 10 ‘Orphan Drugs’ had more than one rare disease indication, with an average peak sales of US$ 34.3 billion in overall sales potential, against around US$ 8.1 billion of the same for drugs with single indication.
  • Time taken for Clinical Trials (CT) focused on orphan drugs is significantly shorter with much quicker review time than trials involving non-orphan drugs.

Conclusion:

Some of the ‘orphan diseases’ are now being diagnosed also in India, and with precision. As the nation takes rapid strides in the medical science, more of such rare diseases are likely to be diagnosed in our country. The global pharma industry has already started taking rapid strides in this area, supported by ODA in various countries. Similar opportunities, both for the patients, as well as, for the industry, need to be made available in India too.

One of the ways to encourage the orphan drug development in India is to follow the model of the Council of Scientific and Industrial Research (CSIR) for ‘Open Source Drug Discovery’ (OSDD)’ with both global and local partnerships and collaboration.

However, speedy enactment of an appropriate ODA for the country, providing adequate financial incentives to the pharma players, for developing and marketing such drugs, both in the local and global markets, at a reasonably affordable price, would go a long way, and be a win-win situation for all.

Alongside, leveraging the knowledge of OSDD acquired by the CSIR, and framing a robust win-win Public Private Partnership (PPP) model to discover and commercialize the orphan drugs, India could well demonstrate the zeal of the country to move beyond the National Policy for Rare Diseases. In that process, it would be able to offer more meaningful and sustainable benefits, both to the domestic pharma industry and the patients, alike, for a long time to come.
