A Patient-Centric State Initiative To Revolutionize Disease Treatment

In his State of the Union address, just before the recent visit to India in January 2015, President Barack Obama articulated the need to develop “Precision Medicine” in his country – a bold, giant and perhaps unprecedented State initiative to remarkably improve effectiveness of disease treatment.

To set the ball rolling, in his budget proposal for the year 2016, President Obama earmarked an amount of US$ 215 million for this purpose. This includes an allocation of US$130 million for the National Institutes of Health (NIH) to create a national research database of about a million American volunteers by studying their genetics together with other relevant factors, such as the environments they live in and the microbes that live in their bodies.

‘Precision Medicine’ initiative is similar to path breaking 13-year and US$3 billion Human Genome Project, that has formed the bedrock of modern genomics, President Obama said. He also expressed hope that the private healthcare sector too, including universities and foundations, will get involved to “lay the foundation” for this new initiative of the Government for the interest of patients.

Why is this approach so relevant in today’s healthcare?

In an article published in the ‘British Medical Journal (BMJ) in October 2012, Richard Smith - an editor of BMJ until 2004 and a Director of the United Health Group’s chronic disease initiative wrote:

“Doctors know that many of the patients they treat with drugs will not benefit. Many patients know that too.”

Dr. Smith also emphasized, for centuries medicine classified diseases by what could be seen, felt, and smelt. Thereafter, medical scientists in this area started defining diseases anatomically, physiologically, and biochemically. Even today, this is by and large the paradigm where most medicines fall.

Smith underscored, because of imprecise diagnosis the treatment also becomes haphazard. There is big variation in how individuals respond to drugs and yet that variation is not usually recorded. The regulators approve drugs based on their average performance even today.

The White House release also reiterates, most medical treatments have been designed for the “average patient.” This “one-size-fits-all-approach,” treatments can be very successful for some patients but not for others.

This calls for broadening the scope of disease treatment – from the conventional and error-prone ‘Disease Oriented’ approach, to relatively more unconventional and better targeted with greater value – ‘Patient-Centric’ ones, wherever needed.

Two current trends:

To address this key deficiency in the effective treatment of several dreaded diseases for many patients, following two are the current trends, as stated by William Pao, M.D., Ph.D., who led Roche’s Oncology Discovery & Translational Area research unit since May 2014:

  • We now know that on a molecular level every cancer is different – not only between different tumors, but even between different areas within a single tumor! This means that we need to match the right drug to the patient who we know will respond best to the drug, at the right time during the course of treatment.
  • Patients will have their tumors profiled not only for genetic drivers, but also for predictive immunotherapy markers at different time points in their course of treatment.

Personalized and Precision Medicine:

The above trends in the endeavor of making treatments more patient specific – thus more effective, have thrown open scientific discourse and intense research on ‘Personalized’ and ‘Precision’ medicines.

As Pfizer has described in its website:

Personalized Medicine is a unique approach to medical practice in which the individual aspects of a patient are directly considered to guide treatment planning, including his or her genetic make-up, key biomarkers, prior treatment history, environmental factors and behavioral preferences. This approach can be used to optimize pharmaceutical treatments and overall care.

Whereas, Precision Medicine is an approach to discovering and developing medicines and vaccines that deliver superior outcomes for patients, by integrating clinical and molecular information to understand the biological basis of disease. Precision medicine is the biopharmaceutical research and development paradigm that will help enable more patient-centered clinical practice, including treatment decision-making based on genetic information – an emerging standard now often described as “personalized medicine”.

As President Obama said while announcing the proposal on January 30, 2015, ‘Precision Medicine’ promises delivery of the right treatment at the right time, every time, to the right person.

He also said that the new effort will “bring us closer to curing diseases like cancer and diabetes…and give all of us access to the personalized information we need to keep ourselves and our families healthier.”

‘Precision Medicines’ Dominate Oncology segment: 

In the European Society for Medical Oncology (ESMO) 2014 Congress, pharma majors reported their latest advances on precision medicines in the cancer care. Bristol-Myers Squibb, Roche, AstraZeneca, GlaxoSmithKline (GSK), and Merck & Co. were among the companies presented updates of their most promising cancer drugs closer to this area.

According to a large pharma lobby group in the United States – The Pharmaceutical Research and Manufacturers of America (PhRMA):

“Recent advances in diseases such as cancer and cystic fibrosis are delivering on the promise of targeted treatments, and between 12 and 50 percent of all compounds currently being researched by the industry are potential personalized medicines. These advances hold great promise in improving patient outcomes and controlling costs by targeting the right medicines to the right patients.”

‘DCAT Connect’ Report of September 2014 also indicates significant increase in ‘Precision Medicines’ in the pipelines of the leading global pharma companies, which is a key change over the past decade.

In 2013, targeted therapies increased their share of the global oncology market, accounting for 46 percent of total sales, up from 11 percent a decade ago. According to IMS Institute for Healthcare Informatics, the global oncology drug market reached US$ 91 billion in 2013 with CAGR of 5.4 percent from 2008 to 2013.

Taking note of this trend, it appears that in the near future ‘Precision Medicines’ would possibly be the most promising class in the treatment of cancer, particularly in breast cancer, lung cancer and certain types of leukemia. This is mainly because medical scientists are already quite acquainted with the molecular signatures of different types of cancer related tumors.

Medical scientists and researchers are also working on ‘Precision Medicines’ to more effectively address many other diseases, such as, diabetes, cardiovascular and ailments related to several types of infections.

Increasing potential:

Realization of the potential of ‘Precision Medicines’ to improve care and speed the development of new treatments has just only begun to be tapped.

In recent times, scientists and researchers have accelerated efforts to understand more about biomarkers for this purpose. A study conducted by the German Association of Research-Based Pharmaceutical Companies (vfa) indicates that more than 20 percent of clinical trials carried out since 2005 focused not just on agents, but also on biomarkers. Before 1990, only one in twenty clinical trials addressed biomarkers.

According to another report, last year, 20 percent of all new drug approvals in the United States were for “Precision Medicine” treatments. This vindicates, yet again, the immense potential to turn genetic discoveries into innovative disease treatments for patients.

A bold state sponsored research initiative:

State funded, ‘Precision Medicine’ initiative is a bold new step of the American Government to revolutionize improvement in healthcare and treating disease. It is expected to pioneer a new model of patient-powered research that promises to accelerate biomedical discoveries and provide clinicians with new tools, knowledge, and therapies to select which treatments will work best for which patients.

As the White House release reiterates, most medical treatments have been designed for the “average patient.” As a result of this, “one-size-fits-all-approach” treatments can be very successful for some patients but not for others. This is changing with the emergence of ‘Precision Medicine’, an innovative approach to disease prevention and treatment that takes into account individual differences in people’s genes, environments, and lifestyles.

In this process, ‘Precision Medicine’ gives clinicians tools to better understand the complex mechanisms underlying a patient’s health, disease, or condition, and to better predict which treatments will be most effective.

Opposite view:

In an op-ed titled, ‘Moonshot’ Medicine Will Let Us Down, published recently in The New York Times, the author argued with his differing viewpoints.

I am quoting below three of those arguments:

  • “For most common diseases, hundreds of genetic risk variants with small effects have been identified, and it is hard to develop a clear picture of who is really at risk for what. This was actually one of the major and unexpected findings of the Human Genome Project. In the 1990s and early 2000s, it was thought that a few genetic variants would be found to account for a lot of disease risk. But for widespread diseases like diabetes, heart disease and most cancers, no clear genetic story has emerged for a vast majority of cases.”
  • “Another unexpected finding of the Human Genome Project was the problem of ‘missing heritability.’ While the statistics suggest that there is a genetic explanation for common conditions and diseases running in families or populations, it turns out that the information on genetic variants doesn’t explain that increased risk.”
  • “The idea behind the “war on cancer” was that a deep understanding of the basic biology of cancer would let us develop targeted therapies and cure the disease. Unfortunately, although we know far more today than we did 40-plus years ago, the statistics on cancer deaths have remained incredibly stubborn.”

I am sure, you will analyze the above points with the facts that you have at your disposal on this subject to arrive at a logical conclusion.

Current Applications:

Though these are still early days, initial benefits of ‘Precision Medicines’ have been reported in many areas, such as:

  • Genetic analysis of patients dealing with blood clots: Since 2007, the U.S. Food and Drug Administration has been recommending genotyping for all patients being assessed for therapy involving Warfarin.
  • Colorectal cancer: For colon cancer patients, the biomarker that predicts how a tumor will respond to certain drugs is a protein encoded by the KRAS gene, which can now be determined through a simple test.
  • Breast cancer: Women with breast tumors can now be effectively screened to determine which receptors their tumor cells contain.
  • Cystic fibrosis: In America, patients with a rare form of cystic fibrosis now can choose a drug designed specifically to target the genetic defect causing their illness. Specialized medical centers, such as “individualized medicine centers” at the Mayo Clinic, are also available to the patients for effective treatment.

Ethical issues:

While following this pursuit of excellence of the genetic scientists in the realm of disease treatment, some experts have reportedly raised flags of caution. They strongly feel that DNA code sequencing brings to light a “very real privacy concerns” of individuals.

GeneWatch UK is an organization that investigates how genetic science and technologies will impact on our food, health, agriculture, environment and society. They have been strongly arguing, if genome sequencing is extended to entire population, individuals and their relatives could then be identified and tracked by matching their DNA with the genome stored in the respective health records. This move, as contemplated by them, could “wipe out privacy” with an impact on the society.

Thus, the ethical and social issues in the development of ‘Precision Medicine’ primarily in the area of genetic testing need to be effectively addressed, sooner.

Conclusion:

The quest for moving away from conventional and error-prone ‘Disease Oriented Treatment’ paving the way for unconventional and value added individual patient-specific ones, may soon come to fruition.

Advances in ‘Precision Medicine’ have already led to powerful new discoveries and several new treatments that are tailored to specific characteristics of individuals, such as a person’s genetic makeup, or the genetic profile of an individual’s tumor.  This is leading to a transformation in the way the world can treat diseases such as cancer.

Patients with breast, lung, and colorectal cancers, melanomas and leukemia, for instance, should be provided with facilities in specialist hospitals to undergo molecular testing as a part of patient care, enabling physicians to select treatments that improve chances of survival and reduce exposure to adverse effects.

Although, the potential for precision medicine to improve care and speed the development of new treatments has only just begun to be tapped, some skeptics do say that tailoring medical treatments to individual characteristics of each patient is both overly optimistic and cost-prohibitive.

Be that as it may, in the balance of probability the benefits of prudent use of ‘Precision Medicine’ far outweigh the concerns expressed. This evolving new paradigm would help saving not just significant expenses, but also precious time that is usually spent on ‘trial-and-error treatments’, by enabling clinicians to determine quickly which therapies are most likely to succeed.

Though lot many grounds would still need to be covered in this area, the State sponsored ‘Precision Medicine’ initiative of America to revolutionize disease treatment, in my view, is indeed a laudable one, every way.

Cheaper Drugs: Happy Patients: Angry Industry

Recent price reductions of a number of cardiovascular and diabetes drugs falling outside the National List of Essential Medicines 2011 (NLEM 2011), have attracted fury of the pharma industry . By a notification dated July 10, 2014, the National Pharmaceutical Pricing Authority (NPPA) has invoked Para 19 of the DPCO 2013 for these price changes, the implications of which would indeed be far reaching.

NPPA has now decided to examine inter-brand price variation for single ingredient formulations in eight therapeutic groups, which, besides cardiovascular and diabetic drugs, would include, anti-cancer, HIV/AIDS, anti-TB, anti-malaria, anti-asthmatic and immunological (sera/vaccines). In these therapy areas, the Maximum Retail Price (MRP) of the brand(s) exceeding 25 per cent of the simple average price of all in the same molecular category having 1 percent or above market share, would be capped at the 25 per cent level.

Pharma industry, in general, feels that this ‘unwelcoming decision’ of the NPPA, which allegedly goes beyond the scope and spirit of DPCO 2013, would invite great uncertainty in its business environment.

On the other hand, many consider this price reduction as a ‘Good Omen’ for millions of patients suffering from related life-long ailments. They argue, the purpose of this ‘Bitter Pill” of the NPPA, is to send a clear message to the pharma industry to shape-up with responsible drug pricing.

The new Minister’s recent statement:

It may not be a bad idea to take into consideration the above notification of the NPPA in the light of what the new minister of Chemicals and Fertilizers – Mr. Ananth Kumar said on May 28, 2014. According to media report, the Minister expressed his intent as follows:

“… As far as branded medicines of multinational pharmaceutical companies are concerned, we will talk to all of them and try to bring down prices of essential drugs for poor by 25-40 per cent… The pharmaceutical industry is very important for the health of the country, he added…our main mission will be to ensure the availability of all necessary medicines at affordable prices, especially for poor across the country.”

It is, therefore, quite possible that the NPPA’s decision on price reduction of cardiovascular and diabetes drugs has the Minister’s concurrence.

Industry’s key concern:

This recent decision of the NPPA has reportedly angered the industry, as the Drug Price Control Order 2013 (DPCO 2013) clearly articulates two basic criteria for drug price control in India, as follows:

1. Span of price control:

This was re-defined (from DPCO 1995) on the ‘essentiality criteria’ of the drugs, which in turn is based on the National List of Essential Medicines 2011 (NLEM 2011)

2. Methodology of price control:

This was re-defined (from DPCO 1995) with a clear departure from ‘Cost-Based Price Control’ to the ‘Market-Based Price Control’.

The industry alleges violation of these criteria for the recently announced price reduction of a number of diabetic and cardiovascular drugs, as those do not fall under NLEM 2011.

Price variation is of no-use to patients for prescription drugs:

As the prices of non-scheduled formulations are not fixed by the NPPA, which can virtually be launched at any price to the market, there has been a huge variation of prices between the branded generics within the same chemical entity/entities. Following is a quick example:

Molecule Disease MRP of Lowest Price Brand MRP of Highest Price Brand
Telmisartan 10’s Hypertension Rs. 25 Rs. 385
Glimeperide 10’s Diabetes Rs. 40 Rs. 133 (Brand Leader)

From this chart, one may be able to fathom some basis in the NPPA’s argument that similar price variations in many branded-generics are of no-consequence for prescription drugs, as doctors decide the medicines that a patient would take. If doctors were influenced to prescribe high priced medicines, the patients would require paying more for those drugs, further increasing their Out of Pocket (OoP) expenses. It is also not uncommon that highest price brands are category-leaders too, as indicated in the table above.

Key lacunae in DPCO 2013:

  •  NLEM 2011 does not cover many combinations of TB drugs, a large number of important drugs for diabetes and hypertension, which I shall deliberate in just a bit.
  • Many other critical life saving medicines, such as, anti-cancer drugs, expensive antibiotics and products needed for organ transplantation have been left out of price control. In fact, the prices of a number of these drugs have reportedly gone up after the notification of DPCO 2013.
  • The government has now reportedly admitted in an affidavit filed before the Supreme Court that the market value and share of medicines covered by new DPCO 2013, as ‘Essential Drugs’, is a meager 18 per cent of the Indian Pharmaceutical Market (IPM).
  • As a result, DPCO 2013 based on NLEM 2011 undermines the entire objective of making essential drugs affordable to all.
  • All these lacunae in the current DPCO 2013 calls for a major revision of NLEM 2011. The Union Health Ministry has reportedly initiated steps to revise the list considering the existing market conditions and usage of drugs by the patients.

Invocation of a ‘Safeguard Provision’ in DPCO 2013:

Probably anticipating this scenario, a key safeguard provision was included in Para 19 of DPCO 2013, which reads as follows:

Fixation of ceiling price of a drug under certain circumstances:

Notwithstanding anything contained in this order, the Government may, in case of extra-ordinary circumstances, if it considers necessary so to do in public interest, fix the ceiling price or retail price of any Drug for such period, as it may deem fit and where the ceiling price or retail price of the drug is already fixed and notified, the Government may allow an increase or decrease in the ceiling price or the retail price, as the case may be, irrespective of annual wholesale price index for that year.”

It now appears, NPPA could realize the key limitations of DPCO 2013, which was put in place rather hastily, in course of its implementation for over one year. Consequently, the patients’ long standing plight with high drug costs for many common life style diseases that are not featuring in NLEM 2011, prompted the the drug regulator in its above notification to bring 108 non-scheduled formulation packs of diabetic, cardiac and other drugs under Para 19 of DPCO 2013, catalyzing an outcry within the pharmaceutical industry in India. Out of these 108 formulation packs, 50 come under anti-diabetic and cardiovascular medicines.

Many important drugs are outside NLEM 2011:

Following is an example of the important cardiovascular and anti-diabetic drugs, which are not featuring in the NLEM 2011 and have now been brought under Para 19 of DPCO 2013:

Sitagliptin, Voglibose, Acarbose, Metformin hcl, Ambrisentan, Amlodipine, Atenolol, Atorvastatin, Bisoprolol, Bosentan,  Gliclazide, Glimepiride, Miglitol, Repaglinide, Pioglitazone, Carvedilol, Clopidogrel, Coumarin, Diltiazem, Dobutamine, Enalapril, Rosuvastatin, Simvastatin, Telmisartan, Terazosin, Torasemide, Trimetazidine and Valsartan, Enoxaparin, Eplerenone, Esatenolol, Fenofibrate, Heparin, Indapamide, Irbesartan, Isosorbide, Ivabradine, Labetalol, Levocarnitine, Lisinopril, Metolazone, Metoprolol, Nebivolol, Nicorandil, Nitroglycerin, Olmesartan, Prasugrel, Prazosin, Propranolol, Ramipril.

More reasons for industry outcry:

As reported in the media, the industry outcry reportedly highlights, besides what I have cited above, the following:

  • The price control order under Para 19 has been notified without any prior consultation with the industry.
  • The manner and method in which this unilateral decision has been taken is untenable.
  • The NPPA’s reasoning, about exploitative pricing by the industry as the reason for such a move, is incorrect given that every product category (in consideration) has approximately 30-70 brand options across price ranges for physicians and patients to choose from. The premise that products are not accessible due to affordability is misplaced. (The above table explains this point).
  • Disease environment was same when the government had cleared the policy and no “extraordinary circumstance” has emerged since then for the regulator to invoke Para 19 in public interest.
  • NPPA has exceeded its brief and gone into policy-making.

NPPA’s rationale for invoking Para 19 of DPCO 2013:

On the other hand, following reasons were cited by the NPPA for taking this decision:

  • The aim of DPCO 2013 is to ensure that essential drugs are available to all at affordable prices. The Supreme Court of India vide its Order dated November 12, 2002 in SLP no. 3668/2003 have directed the Government to ensure that essential and life saving drugs do not fall outside the ambit of price control, which has the force of law.
  • The Ministry of Chemicals and Fertilizers has delegated the powers in respect of specified paragraphs of the DPCO 2013, including paragraph 19, to be exercised by the NPPA on behalf of the Central Government in public interest.
  • There exist huge inter-brand price differences in branded-generics, which is indicative of a severe market failure as different brands of the same drug formulation identical to each other vary disproportionately in terms of price.
  • The different brands of the same drug formulation may sometimes differ in terms of binders, fillers, dyes, preservatives, coating agents, and dissolution agents, but these differences are not significant in terms of therapeutic value.
  • The main reason for market failure is that the demand for medicines is largely prescription driven and the patient has very little choice in this regard.
  • Market failure alone may not constitute sufficient grounds for Government intervention, but when such failure is considered in the context of the essential role that pharmaceuticals play in the area of public health, such intervention becomes necessary. This assumes greater significance, especially when exploitative pricing makes medicines unaffordable and beyond the reach of most, putting huge financial burden in terms of out-of-pocket expenditure on healthcare.
  • There is very high incidence of diabetes in the country, which affects around 61 million persons and the figure is expected to cross 100 million by 2030 as per the projection of the International Diabetes Federation; and it is estimated that every year nearly 1 million people in the country die due to diabetes and hypertension.
  • The drug regulator categorically mentions that In accordance with the guidelines issued by the NPPA, after approval of the ‘Competent Authority’, these price fixations of non-scheduled formulations under Para 19 of DPCO 2013 have been made.

Constituents of the same Ministry with conflicting view points:

Though both NPPA and the Department of Pharmaceuticals (DoP) come under Mr. Ananth Kumar, the new Minister of Chemicals and Fertilizers, both these constituents seem to have conflicting views on this important issue.

The pharma industry reportedly has sought the DoP’s intervention in this matter. The DoP, in turn, is learnt to have requested for the opinion of the Ministry of Law on using ‘Para 19′ provision in favor of public interest by the NPPA, invoking the power assigned to the drug regulator.

Another route for the industry is to legally challenge the said notification of the NPPA. However, one should keep in mind that a PIL is still pending before the Supreme Court questioning the validity DPCO 2013.

The arguments for and against:

Taking all the above points into consideration, the following two important areas of debate have now emerged on this NPPA notification, both in favor and also against:

A. Nothing has materially changed since DPCO 2013 was put in place:

Industry sources highlight that he following two points, that triggered NPPA’s invoking Para 19, have been there for a long time, including the period when the National Pharmaceutical Pricing Policy 2012 (NPPP 2012) was formulated:

-       Huge price differences among various branded generics of the same molecule

-       Cardiovascular ailments and diabetes have assumed endemic proportion

The other group counters that, if mistakes were made while formulating the NPPP 2012 because of intense pressure from vested interests in the erstwhile regime, why corrective actions can’t be taken now?

B. NPPA has exceeded its brief:

Industry sources question, how could NPPA possibly issue such notification of price reduction for non-scheduled formulations, as it is not a policy maker?

Others counter with equal zest: Of course NPPA is not a policy maker, it is a drug price regulator… And as a price regulator, it has implemented Para 19 of DPCO 2013 in the right earnest with the requisite powers conferred on it.

The impact:

According to published data, after the latest price revisions of diabetic and cardiovascular drugs, around 21 per cent of the anti-diabetic drug market faces the ceiling price, while the total market of cardiovascular medicines under price control is now estimated at around 58 per cent, with an overall adverse impact of reportedly Rs 550 Crore on the Indian Pharmaceutical Market. Overall price reduction for these two categories would range between 5 and 35 per cent, the average being around 12 per cent.

MNCs seem to have been hit harder:

An additional bad news for the MNCs is that the scope of Para 19 has now gone beyond the generic space and included even patented product.

For the first time a patented product Sitagliptin has been brought under the purview of Drug price Control order. This decision could give an unprecedented handle to the NPPA to regulate prices of even patented drugs through invocation of Para 19 of DPCO 2013 in future.  Moreover, many high-priced branded generics of MNCs are brand leaders too. Thus, in a relative yardstick, invocation of Para 19 would hit the MNCs harder, creating an uncertainty in their business environment.

Conclusion:

Drug prices are cheapest in India in dollar terms, claims the pharma industry. Does this claim hold much water? May be not, because it should be realistically seen in terms of Purchasing Power Parity (PPP) and Per Capita Income in India. In that sense many would argue that drug prices in India, on the contrary, are not cheaper at all.

Moreover, it is important to take into cognizance the huge inter-brand price differences in branded-generics due to a flawed system, as patients have no role to play in choosing a drug (within the same molecule) that they would need to buy. It is the doctor who is the sole prescription decision maker, where price, per se, may not play a very significant role.

In a situation like this, despite the anger of the industry, many would ponder whether or not NPPA’s engagement and reasoning, on behalf of the Government, to bring some sense in the madness of drug pricing in India be just wished away?

Cheaper medicines in general and generic drugs in particular, would always make the patients and the payor happy, leaving the industry mostly angry.

Keenly observing the recent series of events and taking note of a number of highly credible viewpoints, besides a couple of seemingly spoon-fed, ill-informed and run-of-the mill type editorials, this is about time for the stakeholders to judge without any bias what is right for the country, its people and of course the business to work out a win-win solution, dousing the likes of ‘Fire in The Blood‘, once and for all.
