‘Repurposing’ Older Drugs: Has The Process Started Rolling?

Posted on by

On October 22, 2015, BBC News reported, “The world’s largest clinical trial to examine whether aspirin can prevent cancers returning has begun in the United Kingdom (UK).”

About 11,000 people, who have had early bowel, breast, prostate, stomach and esophageal cancer will be involved in this study with one tablet a day dosage for five years. This trial is being funded by ‘The Charity Cancer Research, UK’ and ‘The National Institute for Health Research (NIHR).’

The scientists feel, if it works, this ‘repurposing’ of an older and much-known drug would be a “game-changing” one. It would then be able to provide a cheap and effective alternative to prevent recurrence of cancer to a large number of cancer survivals. Interestingly, no global pharma players are involved in this cancer prevention research, as yet. 

Aspirin was developed by Bayer way back in 1897 for pain and inflammation. Thereafter, the scientists found a ‘repurpose’ in its use as an anti-platelet drug for treating and preventing heart attacks and strokes.

Similarly, the anti-inflammatory drug Ibuprofen, which was developed by Boots in the 1960s for the treatment of rheumatoid arthritis, is now showing promises that it can help protect against Parkinson’s disease.

Again, a number of studies claim that statins, a cholesterol-reducing drug, can help prevent Alzheimer’s Disease, resulting in low levels of beta-amyloid. Further research needs to be done in this area, as this finding has not been universally accepted, just yet.

All such commendable initiatives, throw open a relevant question for debate: ‘Can the existing drugs be re-examined in a systematic manner to discover their other possible radically new usages at a much lesser treatment costs to patients?’

In my view, available data emphatically prompts the answer ‘Yes’ and I shall deliberate on on that in this article.

‘Repurposing’ older drugs:

The Oxford Dictionary meaning of ‘repurpose’ is: ‘Adapt for use in a different purpose.’

Accordingly, the process of discovering new usages of older drugs is often called by many scientists as ‘repurposing’.   

Currently, we come across various articles reporting a number of such new initiatives. This process is safer, much less expensive and takes much lesser time.

These laudable R&D initiatives needs encouragement from all stakeholders, especially from the Government. Given proper focus and attractive financial and other incentives, more and more players are expected to get attracted to a different genre of innovation. It is a whole new ball game of discovering new purposes of old and cheaper drugs with known and well-documented long term safety profile.

Some old drugs with ‘new purpose’: 

The following table gives an example of some well known older drugs, for which fresh R&D initiatives discovered their new purpose of treatment, at a much cheaper cost: 

Drug Old Indication New purpose
Amantadine Influenza Parkinson’s Disease
Amphotericin Antifungal Leishmaniasis
Aspirin Inflammation, pain Antiplatelet
Bromocriptine Parkinson’s disease Diabetes mellitus
Bupropion Depression Smoking cessation
Colchicine Gout Recurrent pericarditis
Methotrexate Cancer Psoriasis, rheumatoid arthritis

(Source: Indian Journal of Applied Research, Volume: 4, Issue: 8, August 2014)  

A clarion call to join this movement:

The well-known researcher, Dr. Francis S. Collins, the Director of the National Institutes of Health (NIH) in a TED talk (video) strongly argued in favor of ‘translational research’ to produce better drugs, faster. To make this process to work successfully Francis Collins hopes to encourage global pharmaceutical companies to open up their stashes of drugs that have already passed safety tests, but that failed to successfully treat their targeted disease. 

He wants to study, how drugs approved for one disease could successfully treat another or more ailments and also gave examples of the following drugs, which I am quoting below, as such:

  • Raloxifene: The FDA approved Raloxifene to reduce the risk of invasive breast cancer in postmenopausal women in 2007. It was initially developed to treat osteoporosis.
    .
  • Thalidomide: This drug started out as a sedative in the late fifties, and soon doctors were infamously prescribing it to prevent nausea in pregnant women. It later caused thousands of severe birth defects, most notably phocomelia, which results in malformed arms and legs. In 1998, thalidomide found a new use as a treatment for leprosy and in 2006 it was approved for multiple myeloma, a bone marrow cancer.
    .
  • Tamoxifen: This hormone therapy treats metastatic breast cancers, or those that have spread to other parts of the body, in both women and men, and it was originally approved in 1977. Thirty years later, researchers discovered that it also helps people with bipolar disorder by blocking the enzyme PKC, which goes into overdrive during the manic phase of the disorder.
    .
  • Rapamycin: This antibiotic, also called sirolimus, was first discovered in bacteria-laced soil from Easter Island in the seventies, and the FDA approved it in 1999 to prevent organ transplant rejection. Since then, researchers have found it effective in treating not one but two diseases: Autoimmune Lymphoproliferative Syndrome (ALPS), in which the body produces too many immune cells called lymphocytes, and lymphangioleiomyomatosis, a rare lung disease.
    .
  • Lomitapide: Intended to lower cholesterol and triglycerides, the FDA approved this drug to treat a rare genetic disorder that causes severe cholesterol problems called homozygous familial hypercholesterolemia last December.
    .
  • Pentostatin: This drug was created as a chemotherapy for specific types of leukemia. It was tested first in T-cell-related leukemias, which didn’t respond to the drug. But later NIH’s National Cancer Institute discovered that the drug was successful in treating a rare leukemia that is B-cell related, called Hairy Cell Leukemia.
    .
  • Sodium nitrite: This salt was first developed as an antidote to cyanide poisoning and, unrelated to medicine, it’s also used to cure meat. The National Heart, Lung, and Blood Institute is currently recruiting participants for a sodium nitrite clinical trial, in which the drug will be tested as a treatment for the chronic leg ulcers associated with sickle cell and other blood disorders.
  • Zidovudine (AZT): The first antiviral approved for HIV/AIDS in 1987.
  • Farnesyltransferase inhibitor (FTI): This was used to successfully treat children with the rapid-aging disease Progeria in a 2012 clinical trial.

“None of these drugs could have been developed without collaborations between drug developers and researchers with new ideas about applications, based on molecular insights about disease,” Dr. Collins said.

The examples that I have given, so far, on ‘repurposing’ older drugs are not exhaustive, in any way, there are more such examples coming up almost regularly.

The key benefits: 

The key benefits of ‘repurposing’ older drugs may be summarized as follows:

  • Ready availability of the starting compound
  • Previously generated relevant R&D data may be used for submission to drug regulators
  • Makes clinical research more time-efficient and cost-effective
  • Possibility of much quicker market launch

Slowly gaining steam: 

On November 27, 2012, ‘The Guardian’ reported that a number of university-based spin-outs and small biotech companies are being set up in the United States to find new purpose for old drugs. They express interest especially, on those drugs, which were shelved as they did not match the desired efficacy requirements, though showed a good overall safety profile.

Such organizations, take advantage of the declining cost of screening, with some compound libraries, such as, the Johns Hopkins library, which includes 3,500 drugs, available for screening at a small charge, the report highlighted.

Quoting a specialist, the report stated, “Existing drugs have been shown to be safe in patients, so if these drugs could be found to work for other diseases, then this would drastically reduce drug development costs and risks. Of 30,000 drugs in the world, 25,000 are ex-patent – it’s a free-for-all.”

‘Repurposing’ may not attract many pharma players, Government should step in:

Notwithstanding the clarion call of Dr. Francis Collins to global pharma players for their active participation in such projects, I reckon, the positive response may not be too many, because of various reasons.

Although, ‘repurposed’ drugs offer similar or even greater value to patients than any comparable ‘me-too’ New Chemical/Molecular Entity (NCE/NME), there may not possibly be any scope here for ‘Obscene Pricing’, such as ‘Sovaldi’ and many others, as some experts feel. And that’s the reality.

Moreover, new usages of the same old molecule, in all probability, may not get any fresh Intellectual Property (IP) protection in India, either.

Hence, considering the health interest of patients, in general, the Government should assume the role of ‘prime mover’, primarily to set the ball of ‘repurposing of older drugs’ rolling in India. This has already started happening in some of the developed countries of the world, which I shall dwell upon here.

Funding clinical development for ‘repurposing’:

Let me give a couple of examples of funding such admirable initiatives in two different countries.

I have already mentioned above that the clinical development for ‘repurposing’ Aspirin in the prevention of cancer, is being funded by the charity Cancer Research UK and the National Institute for Health Research (NIHR).

In a similar initiative, National Institutes for Health (NIH) of the United States, launched the ‘National Center for Advancing Transnational Sciences (NCATS), in May 2012.

New Therapeutic Uses program of NCATS helps to identify new uses for drugs that have undergone significant research and development by the pharma industry, including safety testing in humans. NIH claims that ‘using drugs that already have cleared several key steps in the development process gives scientists nationwide a strong starting point to contribute their unique expertise and accelerate the pace of therapeutics development.’

By pairing researchers with a selection of specific drugs, NCATS program tests ideas for new therapeutic uses, ultimately identifying promising new treatments for patients. Funding for this purpose is done by NCATS through NIH. For example, In July 2015, NCATS planned a funding of around US$3 million to support four academic research groups to test a selection of drugs for new therapeutic uses, as follows:

  • Type 2 diabetes
  • Glioblastoma (one of the most aggressive brain tumors in adults)
  • Acute myeloid leukemia (an aggressive blood cancer)
  • Chagas disease (a neglected tropical disease that causes heart, digestive and neurological problems)

According to NIH, each award recipient will test a selected drug for its effectiveness against a previously unexplored disease or condition. The industry partners for these projects are AstraZeneca and Sanofi.

Can it be done in India?

Of course yes, provided the Government considers health care as one its priority focus areas with commensurate resource deployment of all kinds for the same.

As things stand today, India still remains beyond any visibility to give a tangible shape to this specific concept of ‘repurposing’ of older drugs. There does not seem to be any other valid reason why similar model of funding can’t be followed locally too, for this purpose.

The nodal agency to spearhead such initiatives, and to create appropriate groundswell to help gain a critical mass, may well be the ‘Council of Scientific & Industrial Research (CSIR)’ or any other body that the Government decides in consultation with domain experts, together with reasonable financial incentives for commercialization of new usages at an affordable cost.

Conclusion:

As we all know, many people, across the world, are currently going through the pain of seeing their loved ones suffer, and even die, from serious ailments, the treatments of which either do not exist or when exist, the therapy costs may be out of reach of a vast majority of patients. In tandem, the R&D pipeline of the global pharma industry is gradually drying up.

In a situation like this, drug ‘repurposing’ that is directed towards meeting unmet medical needs of patients of all types irrespective of financial status, needs to be increasingly encouraged and pursued as a critical solution to this growing problem.

The good news is that some global pharma majors, though very few in number, have now expressed their intention to salvage their failed molecules and are open to help explore whether such drugs may work in other disease conditions.

India seems to be still miles away from this space, and a bit directionless too. That said, the country is scientifically quite capable of making up the lost ground in this area, provided the Government decides so, garnering requisite wherewithal.

Thus, in my view, the process of ‘repurposing’ older drugs has already started rolling in some major countries of the world, in a well structured manner with requisite funding in place. Tangible outcomes are already noticeable today, with some examples quoted in this article.

As Dr. Francis Collins said, collaborations between drug developers and researchers with new ideas about applications, based on molecular insights about disease are critical in the way forward to achieve this cherished goal in a sustainable manner.

Would ‘Regenerative Medicine’ Shape The Future Of Global Healthcare?

Posted on by

Just the last week, on December 19, 2014, international media broke the news of regulatory approval of the first stem cell treatment by the European Medicines Agency (EMA).

The Agency reportedly has recommended an Orphan Drug – Holoclar of the Italian pharmaceutical company Chiesi Farmaceutici S.p.A for the treatment of moderate-to-severe Limbal Stem Cell Deficiency (LSCD) caused due to physical or chemical burns to the eyes in adults. LSCD can lead to blindness, where Holocar works in around 80 percent of cases.

The EMA decision to approve Holoclar will now be sent to the European Commission for market authorization.

As reported, this new generation treatment takes a small sample of the patients’ healthy cornea, removes the stem cells and grows them until there are sufficient numbers to put back into the eye. The cells themselves then repair the damage.

Experts consider this development as very significant step forward, as stem-cell therapies are now being tried mostly in the laboratory environment and clinical trials.

Treatment with Stem Cells – A new paradigm:

A stem cell is defined as an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.

Stem cells are, therefore, immature cells that can be induced to transform into tissue or organ-specific cells and are classified as per their source, such as Embryonic Stem Cells (ES) from early human embryos, fetal stem cells from aborted fetus; adult stem cells from tissues, skin and bone marrow; cord blood cells from umbilical cord and even fatty tissues.

In human developmental biology, extensive scientific research over many years has led to the discovery of human stem cells.

Regenerative Medicine:

This terminology is generally used for new medical advances in which an understanding of the human genome allows the use of the body’s own mechanism to heal it. This may include new pharmaceuticals and the ability to create new cells that could be implanted into patients to replace diseased or missing tissues.

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 would unfold a new paradigm, 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.

Some promising developments:

Besides the recently EMA approved new treatment, as mentioned above, examples of just a few more promising developments in research with the stem cells, are as follows:

- Possible cure for Type 1 diabetes:

According to an international report of 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. Around 10 per cent of all diabetes is Type 1, but 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.

- Transplant of embryonic human stem cells on patients with macular degeneration partially restored vision:

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 could be just a few years away:

Yet another 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 heart transplant. Of course, if the patients are willing and can afford so.

Debate around stem cell research:

Like many other research areas involving biological science, a raging debate has also commenced globally on several sociopolitical, cultural and ethical issues involving the use of stem cells as therapy.

Many clinical research related issues too are now surfacing on the use of human embryos, manipulations and modifications in stem cells research.

Apprehension of misuse, especially through cloning, had prompted many governments, India included, to ban reproductive cloning, keeping therapeutic cloning open for research.

However, arriving at a broader consensus in this area does not seem to be an insurmountable problem, in any case, as things stand today.

Research on stem cells and regenerative medicine in India:

Though it may sound almost unbelievable, India is now considered to be in the forefront of stem cells research and its use in a limited manner.

Indian Government under Indian Council for Medical Research (ICMR) and the Department of Biotechnology (DBT) has already set up a number of stem cell research institutions across the country. These institutions have already commenced valuable research in this area. DBT had granted more than Rs 300 Crore over the previous five years to be used in basic and applied research in stem cell technology.

According to one August 2014 report from ‘Business Insider’, several stem cells research initiatives are ongoing both in public and the private sectors in India.

A few examples, as reported, are as follows:

Public initiatives:

  • The National Centre for Cell Research (NCCR), Pune, has worked on stem cell trans differentiation into pancreatic islets.
  • Research at All India Institute of Medical Science (AIIMS) and Postgraduate Institute of Medical Education & Research (PGIMER), is ongoing on retinal degeneration and stroke.
  • National Institute of Immunohematology (NIIH) has been able to differentiate umbilical cord-derived mesenchymal stem cells into cardiomyocytes or cardiac muscles.
  • The National Centre for Biological Sciences (NCBS) in Bangalore, part of the Tata Institute of Fundamental Research, also works closely with the government on stem cells research.
  • The Government of India had set up The Centre for Stem Cell Research (CSCR) in 2008 in collaboration with Christian Medical College, Vellore, with the intention of using stem cell science for understanding human diseases and development of stem cell-based therapies. Interestingly, it also runs a training program for scientists and students of stem cell research. CSCR will also carry out clinical trials with stem cells produced under current good manufacturing practice (GMP) conditions.

Private initiatives:

  • Reliance Life Sciences obtained permission to use on large-scale stem cells sourced from the patient’s body for therapy.
  • The LV Prasad Eye Institute, Hyderabad, has developed corneal limbal stem cells.
  • Sankara Nethralaya Stem Cell Research Center, Chennai, is working on retinal and corneal stem cell application and immunoregulatory properties of stem cells.
  • Hospitals such as Dr KM Cherian’s research facility in Medville have used stem cells from bone marrow to help regenerate the heart.

Besides, Indian rules and law permit the usage of one’s own banked stem cells. Several storage facilities such as Life Cell, Reliance Life Sciences, Cryobanks International and Stemade for dental stem cell storage have also come up.

Stem cells research guidelines in India:

In India, ICMR-DBT Guidelines for Stem Cell Research are in place. These guidelines have been laid down to ensure that research with human stem cells is conducted in a responsible and ethically sensitive manner and complies with all regulatory requirements pertaining to biomedical research in general and stem cell research in particular.

Since it is a rapidly evolving field of science, the recommendations may change with time.

All types of research and clinical trials in stem cells would require to be registered with and obtain prior permission and approval of the National Apex Committee (NAC) and the Institutional Committee (IC-SCRT) for Stem Cell Research.

It is notably important that the guidelines categorically states that only stem cell research, basic and translational, is permitted but not therapy.

NAC- IC-SCRT permits therapy usage in patients only through approved and fully monitored clinical trials. Stem cells cannot be used as therapy without appropriate regulatory approvals in India.

Conclusion:

Currently, most treatments for non-infectious chronic ailments only delay the disease progression and associated complications. There is virtually no cure for most of these diseases, which include, spinal injuries, heart diseases, Parkinson’s, Alzheimer’s disease or even hypertension, asthma or diabetes.

Regenerative Medicine would not just bring down the cost of healthcare 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 is mostly being conducted by various academia of global repute along with the industry. This emerging trend sends a clear signal that ‘Regenerative Medicine’ is now strongly poised to give an altogether new shape to the future of global healthcare, adding unique dimensions.

Consequential paradigm shift in the field of healthcare, I reckon, would herald the dawn of a brand new era, setting in place a whole new commercial ball game, the like of which the world has never witnessed, ever before.

“Make in India…Sell Anywhere in The World”: An Indian Pharma Perspective

Posted on by

In his Independent Day speech from the ramparts of the Red Fort on August 15, 2014, Indian Prime Minister Modi gave a clarion call to all investors of the world, “Come, make in India”, “Come, manufacture in India”, “Sell in any country of the world, but manufacture here”.

The Prime Minister did not stop there. In his inimitable style, following it through on September 25, 2014 he gave an official status to ‘Make in India’ slogan and launched a global campaign.

“My definition of FDI for the people of India is First Develop India. This is also a responsibility for the people of India,” he further clarified.

An Indian perspective:

If I juxtapose this vision of the Prime Minister in the Indian pharmaceutical industry perspective, one finds that many small, medium and large size local domestic manufacturers are currently manufacturing drugs not just for the domestic market, but are also exporting in large quantities to various countries of the world, including, North America, South America and Europe.

The United States (US) is one of the most critical markets for majority of the Indian drug exporters. This transaction was taking place without any major regulatory hitches since quite some time. Unfortunately, over the last few years, mostly the Federal Drug Administration of the US (USFDA) and the United Kingdom (UK)’s Medicines and Healthcare Products Regulatory Agency (MHRA) have started raising serious doubts on the quality of medicines manufactured in India, making a significant impact on the drug exports of the country.

Most of these quality issues are related to ‘Data Integrity’ in the dug manufacturing and its documentation processes.

The impact:

According to industry data, in 2013-14, Indian drug exports registered the slowest growth in nearly the last 15 years. In this fiscal year, pharma exports of the country with a turnover of US$ 14.84 billion grew at a meager 1.2 percent. Pharmexcil attributed its reason to USFDA related regulatory issues and increasing global competition.

US accounts for about 25 percent of India’s pharma exports and its Federal Drug Administration (USFDA) has been expressing, since quite a while, serious concerns on ‘Data Integrity’ at the agency’s  previously approved production facilities of a large number of Indian pharma players.

The issue is causing not just a serious concern to USFDA and some other overseas drug regulatory agencies, but also posing a huge threat to future growth potential of Indian drug exports.

It is worth noting that Indian government had set an objective, in its strategy document, to register a turnover of US$ 25 billion for pharma exports in 2014-15. In all probability, it would fall far short of this target at the end of this fiscal, predominantly for related reasons.

Why is so much of ‘fuss’ on ‘Data Integrity’?

Broadly speaking, ‘Data Integrity’ in pharmaceutical manufacturing ensures that finished products meet pre-established specifications, such as, for purity, potency, stability and sterility. If data integrity is breached in any manner or in absence of credible data, the product becomes of dubious quality in the eyes of drug regulators.

Manufacturing related ‘Data Integrity’ is usually breached, when data from a database is deliberately or otherwise modified or destroyed or even cooked.

Over the last several years, ‘Data Integrity’ related issues in India are attracting enormous attention of both the USFDA and the MHRA, UK. As a result, concerned pharma manufacturing facilities are receiving Import Alerts/Warning Letters from the respective overseas drug regulators, refusing entry of those medicines mostly in the United States and some in the UK.

Recent warning letters:

Just over a year – from May 2013 to July 2014, around a dozen ‘Warning Letters’ have been sent to the Indian drug manufacturers by the USFDA on ‘Data Integrity’ related issue, as follows:

Recent ‘Warning Letter’ issued to: Date of issue
1. Marck Biosciences Ltd. 08. 07. 2014
2. Apotex Pharmachem India Pvt Ltd. 17. 06. 2014
3. Sun Pharmaceutical Industries 07. 05. 2014
4. Canton Laboratories Private Limited 27. 02. 2014
5. USV Limited 06. 02. 2014
6. Wockhardt Limited 25. 11. 2013
7. Agila Specialties Private Limited 09. 09. 2013
8. Posh Chemicals Private Limited 02. 08. 2013
9. Aarti Drugs Limited 30. 07. 2013
10. Wockhardt Limited 18. 07. 2013
11. Fresenius Kabi Oncology Ltd 01. 07. 2013
12. RPG Life Sciences Limited 28. 05. 2013

(Source: RAPS, 19 August 2014)

Another report states that USFDA has, so far, banned at least 36 manufacturing plants in India from selling products in the US.

Importance of US for Indian generic players:

Generic drugs currently contribute over 80 percent of prescriptions written in the US. Around 40 percent of prescriptions and Over The Counter (OTC) drugs that are sold there, come from India. Almost all of these are cheaper generic versions of patent expired drugs. Hence, India’s commercial stake in this area is indeed mind-boggling.

The ‘Data Integrity’ issue is not restricted to just US or UK:

A report quoting researchers led by Roger Bate, an American Enterprise Institute scholar and funded by the The Legatum Institute and the Humanities Research Council of Canada, concluded that many Indian pharma companies follow double manufacturing standards, as they are sending poor quality drugs to Africa compared to the same pills sold in other countries. This study was based on tests of 1,470 samples produced by 17 Indian drug manufacturers.

Besides India, the researchers took drug samples from pharmacies in Africa and middle-income countries, including China, Russia and Brazil.

According to this paper, the researchers found that 17.5 percent of samples of the tuberculosis therapy rifampicin sold in Africa tested substandard, which means the drug has less than 80 percent of the active ingredient than what it should otherwise. Against this number, in India, 7.8 percent of the medicine sampled was found substandard.

Moreover, Almost 9 percent of samples of the widely used antibiotic ciprofloxacin sold in Africa tested substandard, as compared to 3.3 percent in India.

Thorny issues around golden opportunities:

Much reported breach in manufacturing ‘Data Integrity’ detected at the manufacturing sites in India, are throwing fresh doubts on the efficacy and safety profile of generic/branded generic medicines, in general, produced in the country and more importantly, whether they are putting the patients’ health at risk.

A new analysis by the U.S. National Bureau of Economic Research pointed out some thorny issues related to ‘Data Integrity’ of drugs produced by the Indian pharmaceutical companies, which supply around 40 percent of the generic drugs sold in the United States, as stated above.

The researchers examined nearly 1,500 India-made drug samples, collected from 22 cities and found that “up to 10 percent of some medications contained insufficient levels of the key active ingredients or concentrations so low, in fact, that they would not be effective against the diseases they’re designed to treat.”

The report also highlighted that international regulators detected more than 1,600 errors in 15 drug applications submitted by Ranbaxy. The Bureau Officials commented that these pills were “potentially unsafe and illegal to sell.”

Frequent drug recalls by Indian pharma majors:

The above findings came in tandem with a series of drug recalls made recently by the Indian pharma companies in the US.

Some of the reported recent drug recalls in America, arising out of manufacturing related issues at the facilities of two well-known Indian pharma majors, which are going to merge soon, are as follows:

  • Sun Pharmaceuticals recalled nearly 400,000 bottles of the decongestant cetirizine (Zyrtec) and 251,882 of the antidepressant venlafaxine (Effexor) this May, because the pills failed to dissolve properly. The drugs were distributed by the drug maker’s US subsidiary Caraco Pharmaceutical Laboratories, but were manufactured in India.
  • In the same month – May, Ranbaxy recalled 30,000 packs of the allergy drugs loratadine and pseudo-ephedrine sulphate extended release tablets because of manufacturing defects in packaging.
  • In March, Sun Pharma recalled a batch of a generic diabetes drug bound for the US after an epilepsy drug was found in it. A patient discovered the error after noticing the wrong medication in the drug bottle.
  • Again in March, Ranbaxy recalled nearly 65,000 bottles of the statin drug atorvastatin calcium (Lipitor) after 20-milligram tablets were found in sealed bottles marked 10-milligrams. A pharmacist in the U.S. discovered the mix up.

Indian media reinforces the point:

Indian media (TNN) also reported that there is no quality control even for life-saving generic drugs and the government is apathetic on ensuring that the quality protocol of these drugs is properly observed.

This happens, as the report states, despite government’s efforts to push generic drugs, as they are more affordable. The report gave an example of a life-saving drug, Liposomal Amphotericin B, which is used to treat fungal infections in critically ill patients.

Are all these drugs safe enough for Indian Patients?

Though sounds awkward, it is a fact that India is a country where ‘export quality’ attracts a premium. Unintentionally though, with this attitude, we indirectly accept that Indian product quality for domestic consumption is not as good.

Unfortunately, in the recent years, increasing number of even ‘export quality’ drug manufacturing units in India are being seriously questioned, warned and banned by the overseas drug regulators, such as USFDA and MHRA, UK, just to ensure dug safety for the patients in their respective countries.

Taking all these into consideration, and noting increasing instances of blatant violations of cGMP standards and ‘Data Integrity’ requirements for ‘export quality’ drugs, one perhaps would shudder to think, what could possibly be the level of conformance to cGMP for the drugs manufactured solely for the consumption of local patients in India.

A cause of concern, as generic drugs are more cost effective to patients:

It has been widely recognized globally that the use of generic drugs significantly reduces out-of-pocket expenditure of the patients and also payers’ spending.

The findings of a study conducted by the Researchers from Brigham and Women’s Hospital (BWH), Harvard Medical School and CVS Health has just been published in the Annals of Internal Medicine on September 15, 2014. In this study the researchers investigated whether the use of generic versus brand name statins can play a role in medication adherence and whether or not this leads to improved health outcomes. The study concluded that patients taking generic statins were more likely to adhere to their medication and also had a significantly lower rate of cardiovascular events and death.

In this study, the mean co-payment for the generic statin was US$10, as against US$48 for brand-name statins. It is generally expected that the generic drugs would be of high quality, besides being affordable.

I deliberated on a related subject in one of my earlier blog posts of November 11, 2013 titled, “USFDA” Import Bans’: The Malady Calls For Strong Bitter Pills”.

Conclusion:

According to USFDA data, from 2013 onwards, about 20 drug manufacturing facilities across India attracted ‘Import Alerts’ as against seven from China, two each from Australian, Canadian and Japanese units and one each from South African and German facilities.

Unfortunately, despite intense local and global furore on this subject, Indian drug regulators at the Central Drugs Standard Control Organization (CDSCO), very strangely, do not seem to be much concerned on the ‘Data Integrity’ issue, at least, not just yet.

In my view, ‘Data Integrity’ issues are mostly not related to any technical or other knowledge deficiency. From the “Warning Letters” of the USFDA to respective Indian companies, it appears that these breaches are predominantly caused by falsification or doctoring of critical data. Thus, it basically boils down to a mindset issue, which possibly pans across the Indian pharma industry, irrespective of size of operations of a company.

Indian Prime Minister’s passionate appeal aimed at all investors, including from India, to “Make in India” and “Sell Anywhere in The World”, extends to pharma industry too, both local and global. The drug makers also seem to be aware of it, but the ghost keeps haunting unabated, signaling that the core mindset has remained unchanged despite periodic lip service and public utterances for corrective measures by a number of head honchos.

Any attempt to trivialize this situation, I reckon, could meet with grave consequences, jeopardizing the thriving pharma exports business of India, and in that process would betray the Prime Ministers grand vision for the country that he epitomized with, “Make in India” and “Sell Anywhere in The World”.

R&D: Is Indian Pharma Moving Up the Value Chain?

Posted on by

It almost went unnoticed by many, when in the post product patent regime, Ranbaxy launched its first homegrown ‘New Drug’ of India, Synriam, on April 25, 2012, coinciding with the ‘World Malaria Day’. The drug is used in the treatment of plasmodium falciparum malaria affecting adult patients.  However, the company has also announced its plans to extend the benefits of Synriam to children in the malaria endemic zones of Asia and Africa.

The new drug is highly efficacious with a cure rate of over 95 percent offering advantages of “compliance and convenience” too. The full course of treatment is one tablet a day for three days costing less than US$ 2.0 to a patient.

Synriam was developed by Ranbaxy in collaboration with the Department of Science  and Technology of the Government of India. The project received support from the Indian Council of Medical Research (ICMR) and conforms to the recommendations of the World Health Organization (WHO). The R&D cost for this drug was reported to be around US$ 30 million. After its regulatory approval in India, Synriam is now being registered in many other countries of the world.

Close on the heels of the above launch, in June 2013 another pharmaceutical major of India, Zydus Cadilla announced that the company is ready for launch in India its first New Chemical Entity (NCE) for the treatment of diabetic dyslipidemia. The NCE called Lipaglyn has been discovered and developed in India and is getting ready for launch in the global markets too.

The key highlights of Lipaglyn are reportedly as follows:

  • The first Glitazar to be approved in the world.
  • The Drug Controller General of India (DCGI) has already approved the drug for launch in India.
  • Over 80% of all diabetic patients are estimated to be suffering from diabetic dyslipidemia. There are more than 350 million diabetics globally – so the people suffering from diabetic dyslipidemia could be around 300 million.

With 20 discovery research programs under various stages of clinical development, Zydus Cadilla reportedly invests over 7 percent of its turnover in R&D.  At the company’s state-of-the-art research facility, the Zydus Research Centre, over 400 research scientists are currently engaged in NCE research alone.

Prior to this in May 14, 2013, the Government of India’s Department of Biotechnology (DBT) and Indian vaccine company Bharat Biotech jointly announced positive results, having excellent safety and efficacy profile in Phase III clinical trials, of an indigenously developed rotavirus vaccine.

The vaccine name Rotavac is considered to be an important scientific breakthrough against rotavirus infections, the most severe and lethal cause of childhood diarrhea, responsible for approximately 100,000 deaths of small children in India each year.

Bharat Biotech has announced a price of US$ 1.00/dose for Rotavac. When approved by the Drug Controller General of India, Rotavac will be a more affordable alternative to the rotavirus vaccines currently available in the Indian market. 

It is indeed interesting to note, a number of local Indian companies have started investing in pharmaceutical R&D to move up the industry value chain and are making rapid strides in this direction.

Indian Pharma poised to move-up the value-chain:

Over the past decade or so, India has acquired capabilities and honed skills in several important areas of pharma R&D, like for example:

  • Cost effective process development
  • Custom synthesis
  • Physical and chemical characterization of molecules
  • Genomics
  • Bio-pharmaceutics
  • Toxicology studies
  • Execution of phase 2 and phase 3 studies

According to a paper titled, “The R&D Scenario in Indian Pharmaceutical Industry” published by Research and Information System for Developing Countries, over 50 NCEs/NMEs of the Indian Companies are currently at different stages of development, as follows:

Company Compounds Therapy Areas Status
Biocon 7 Oncology, Inflammation, Diabetes Pre-clinical, phase II, III
Wockhardt 2 Anti-infective Phase I, II
Piramal Healthcare 21 Oncology, Inflammation, Diabetes Lead selection, Pre-clinical, Phase I, II
Lupin 6 Migraine, TB, Psoriasis, Diabetes, Rheumatoid Arthritis Pre-clinical, Phase I, II, III
Torrent 1 Diabetic heart failure Phase I
Dr. Reddy’s Lab 6 Metabolic/Cardiovascular disorders, Psoriasis, migraine On going, Phase I, II
Glenmark 8 Metabolic/Cardiovascular /Respiratory/Inflammatory /Skin disorders, Anti-platelet, Adjunct to PCI/Acute Coronary Syndrome, Anti-diarrheal, Neuropathic Pain, Skin Disorders, Multiple Sclerosis, Ongoing, Pre-clinical, Phase I, II, III

R&D collaboration and partnership:

Some of these domestic companies are also entering into licensing agreements with the global players in the R&D space. Some examples are reportedly as follows:

  • Glenmark has inked licensing deals with Sanofi of France and Forest Laboratories of the United States to develop three of its own patented molecules.
  • Domestic drug major Biocon has signed an agreement with Bristol Myers Squibb (BMS) for new drug candidates.
  • Piramal Life Sciences too entered into two risk-reward sharing deals in 2007 with Merck and Eli Lilly, to enrich its research pipeline of drugs.
  • Jubilant Group partnered with Janssen Pharma of Belgium and AstraZeneca of the United Kingdom for pharma R&D in India, last year.

All these are just indicative collaborative R&D initiatives in the Indian pharmaceutical industry towards harnessing immense growth potential of this area for a win-win business outcome.

The critical mass:

An international study estimated that out of 10,000 molecules synthesized, only 20 reach the preclinical stage, 10 the clinical trials stage and ultimately only one gets regulatory approval for marketing. If one takes this estimate into consideration, the research pipeline of the Indian companies would require to have at least 20 molecules at the pre-clinical stage to be able to launch one innovative product in the market.

Though pharmaceutical R&D investments in India are increasing, still these are not good enough. The Annual Report for 2011-12 of the Department of Pharmaceuticals indicates that investments made by the domestic pharmaceutical companies in R&D registered an increase from 1.34 per cent of sales in 1995 to 4.5 percent in 2010. Similarly, the R&D expenditure for the MNCs in India has increased from 0.77 percent of their net sales in 1995 to 4.01 percent in 2010.

Thus, it is quite clear, both the domestic companies and the MNCs are not spending enough on R&D in India. As a result, at the individual company level, India is yet to garner the critical mass in this important area.

No major R&D investments in India by large MNCs:

According to a report, major foreign players with noteworthy commercial operations in India have spent either nothing or very small amount towards pharmaceutical R&D in the country. The report also mentions that Swiss multinational Novartis, which spent $ 9 billion on R&D in 2012 globally, does not do any R&D in India.

Analogue R&D strategy could throw greater challenges:

For adopting the analogue research strategy, by and large, the Indian pharma players appear to run the additional challenge of proving enhanced clinical efficacy over the known substance to pass the acid test of the Section 3(d) of the Patents Act of India.

Public sector R&D:

In addition to the private sector, research laboratories in the public sector under the Council for Scientific and Industrial Research (CSIR) like, Central Drug Research Institute (CDRI), Indian Institute of Chemical Technology (IICT) and National Chemical Laboratory (NCL) have also started contributing to the growth of the Indian pharmaceutical industry.

As McKinsey & company estimated, given adequate thrust, the R&D costs in India could be much lower, only 40 to 60 per cent of the costs incurred in the US. However, in reality R&D investments of the largest global pharma R&D spenders in India are still insignificant, although they have been expressing keenness for Foreign Direct Investments (FDI) mostly in the brownfield pharma sector.

Cost-arbitrage:

Based on available information, global pharma R&D spending is estimated to be over US$ 60 billion. Taking the cost arbitrage of India into account, the global R&D spend at Indian prices comes to around US$ 24 billion. To achieve even 5 percent of this total expenditure, India should have invested by now around US$ 1.2 billion on the pharmaceutical R&D alone. Unfortunately that has not been achieved just yet, as discussed above.

Areas of cost-arbitrage:

A survey done by the Boston Consulting Group (BCG) in 2011 with the senior executives from the American and European pharmaceutical companies, highlights the following areas of perceived R&D cost arbitrage in India:

Areas % Respondents
Low overall cost 73
Access to patient pool 70
Data management/Informatics 55
Infrastructure set up 52
Talent 48
Capabilities in new TA 15

That said, India should realize that the current cost arbitrage of the country is not sustainable on a longer-term basis. Thus, to ‘make hay while the sun shines’ and harness its competitive edge in this part of the world, the country should take proactive steps to attract both domestic as well as Foreign Direct Investments (FDI) in R&D with appropriate policy measures and fiscal incentives.

Simultaneously, aggressive capacity building initiatives in the R&D space, regulatory reforms based on the longer term need of the country and intensive scientific education and training would play critical role to establish India as an attractive global hub in this part of the world to discover and develop newer medicines for all.

Funding:

Accessing the world markets is the greatest opportunity in the entire process of globalization and the funds available abroad could play an important role to boost R&D in India. Inadequacy of funds in the Indian pharmaceutical R&D space is now one of the greatest concerns for the country.

The various ways of funding R&D could be considered as follows:

  • Self-financing Research: This is based on:
  1. “CSIR Model”: Recover research costs through commercialization/ collaboration with industries to fund research projects.
  2. “Dr Reddy’s Lab / Glenmark Model”: Recover research costs by selling lead compounds without taking through to development.
  • Overseas Funding:  By way of joint R&D ventures with overseas collaborators, seeking grants from overseas health foundations, earnings from contract research as also from clinical development and transfer of aborted leads and collaborative projects on ‘Orphan Drugs’.
  • Venture Capital & Equity Market:  This could be both via ‘Private Venture Capital Funds’ and ‘Special Government Institutions’.  If regulations permit, foreign venture funds may also wish to participate in such initiatives. Venture Capital and Equity Financing could emerge as important sources of finance once track record is demonstrated and ‘early wins’ are recorded.
  • Fiscal & Non-Fiscal Support: Should also be valuable in early stages of R&D, for which a variety of schemes are possible as follows:
  1. Customs Duty Concessions: For Imports of specialized equipment, e.g. high throughput screening equipment, equipment for combinatorial chemistry, special analytical tools, specialized pilot plants, etc.
  2. Income tax concessions (weighted tax deductibility): For both in-house and sponsored research programs.
  3. Soft loans: For financing approved R&D projects from the Government financial institutions / banks.
  4. Tax holidays: Deferrals, loans on earnings from R&D.
  5. Government funding: Government grants though available, tend to be small and typically targeted to government institutions or research bodies. There is very little government support for private sector R&D as on date.

All these schemes need to be simple and hassle free and the eligibility criteria must be stringent to prevent any possible misuse.

Patent infrastructure:

Overall Indian patent infrastructure needs to be strengthened, among others, in the following areas:

  • Enhancement of patent literacy both in legal and scientific communities, who must be taught how to read, write and file a probe.
  • Making available appropriate ‘Search Engines’ to Indian scientists to facilitate worldwide patent searches.
  • Creating world class Indian Patent Offices (IPOs) where the examination skills and resources will need considerable enhancement.
  • ‘Advisory Services’ on patents to Indian scientists to help filing patents in other countries could play an important role.

Creating R&D ecosystem:

  • Knowledge and learning need to be upgraded through the universities and specialist centers of learning within India.
  • Science and Technological achievements should be recognized and rewarded through financial grants and future funding should be linked to scientific achievements.
  • Indian scientists working abroad are now inclined to return to India or network with laboratories in India. This trend should be effectively leveraged.

Universities to play a critical role:

Most of Indian raw scientific talents go abroad to pursue higher studies.  International Schools of Science like Stanford or Rutgers should be encouraged to set up schools in India, just like Kellogg’s and Wharton who have set up Business Schools. It has, however, been reported that the Government of India is actively looking into this matter.

‘Open Innovation’ Model:

As the name suggest, ‘Open Innovation’ or the ‘Open Source Drug Discovery (OSDD)’ is an open source code model of discovering a New Chemical Entity (NCE) or a New Molecular Entity (NME). In this model all data generated related to the discovery research will be available in the open for collaborative inputs. In ‘Open Innovation’, the key component is the supportive pathway of its information network, which is driven by three key parameters of open development, open access and open source.

Council of Scientific and Industrial Research (CSIR) of India has adopted OSDD to discover more effective anti-tubercular medicines.

Insignificant R&D investment in Asia-Pacific Region:

Available data indicate that 85 percent of the medicines produced by the global pharmaceutical industry originate from North America, Europe, Japan and some from Latin America and the developed nations hold 97 percent of the total pharmaceutical patents worldwide.

MedTRACK reveals that just 15 percent of all new drug development is taking place in Asia-Pacific region, including China, despite the largest global growth potential of the region.

This situation is not expected to change significantly in the near future for obvious reasons. The head start that the western world and Japan enjoy in this space of the global pharmaceutical industry would continue to benefit those countries for some more time.

Some points to ponder:

  • It is essential to have balanced laws and policies, offering equitable advantage for innovation to all stakeholders, including patients.
  • Trade policy is another important ingredient, any imbalance of which can either reinforce or retard R&D efforts.
  • Empirical evidence across the globe has demonstrated that a well-balanced patent regime would encourage the inflow of technology, stimulate R&D, benefit both the national and the global pharmaceutical sectors and most importantly improve the healthcare system, in the long run.
  • The Government, academia, scientific fraternity and the pharmaceutical Industry need to get engaged in various relevant Public Private Partnership (PPP) arrangements for R&D to ensure wider access to newer and better medicines in the country, providing much needed stimulus to the public health interest of the nation.

Conclusion:

R&D initiatives, though very important for most of the industries, are the lifeblood for the pharmaceutical sector, across the globe, to meet the unmet needs of the patients. Thus, quite rightly, the pharmaceutical Industry is considered to be the ‘lifeline’ for any nation in the battle against diseases of all types.

While the common man expects newer and better medicines at affordable prices, the pharmaceutical industry has to battle with burgeoning R&D costs, high risks and increasingly long period of time to take a drug from the ‘mind to market’, mainly due to stringent regulatory requirements. There is an urgent need to strike a right balance between the two.

In this context, it is indeed a proud moment for India, when with the launch of its home grown new products, Synriam of Ranbaxy and Lipaglyn of Zydus Cadilla or Rotavac Vaccine of Bharat Biotech translate a common man’s dream of affordable new medicines into reality and set examples for others to emulate.

Thus, just within seven years from the beginning of the new product patent regime in India, stories like Synriam, Lipaglyn, Rotavac or the R&D pipeline of over 50 NCEs/NMEs prompt resurfacing the key unavoidable query yet again:

Has Indian pharma started catching-up with the process of new drug discovery, after decades of hibernation, to move up the industry ‘Value Chain’?

Vaccines Development: Is it Just a Business Based on Fear?

Posted on by
Reply

‘Vaccination – A Business based on fear’, is the title of a book written by Dr. Gerhard Buchwald M.D, a German medical doctor and a vaccination critic. This book talks about:

“The damage and the deaths caused by vaccination are written off as ‘pure coincidence’, as something which would have occurred anyway, even without vaccination. Often damage is trivialized by claiming that vaccine damage occurs only very, very rarely, or the damage is covered up by naming as the cause, the most unlikely syndromes which can only be found in special literature.”

However, his critics and pro-vaccination experts do opine that this book “is a pathetic presentation of vaccination, from a self-proclaimed anti-vaccination lobbyist. It is full of half-truths, blatant lies and misrepresented statistics”.

Vaccination – one of the most important development in medicines: 

Quite in contrary to what Dr. Gerhard Buchwald wrote, 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’ in 2007. No wonder, 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.

Vaccines that are being developed and marketed today, though provide high level of protection against increasing number of diseases with reduction of associated morbidity and mortality, there is still a crying need for greater encouragement, more resource deployment and sharper focus towards newer vaccines development for many more dreaded and difficult diseases.

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

Rejuvenating trend:

However, from the business perspective, the vaccine market, though initially considered to be a low-profit initiative, now has started being under rejuvenated focus keeping pace with improved understanding of the human immune system. The future scope of vaccines is immense, as the management of several potentially preventable diseases remains still unaddressed.

Consequently, the focus of the global vaccine industry is getting expanded from prophylactic vaccination for communicable disease (e.g. DTP vaccine) to therapeutic vaccines (e.g. Anti-cancer vaccines) and then possibly non-communicable disease vaccines (e.g. vaccines for coronary artery disease).

Shifting focus on vaccines types:

As per the ‘National Institute of Health (NIH)’ of USA, following are some types of vaccines that researchers usually work on:

  • Live, attenuated vaccines
  • Inactivated vaccines
  • Subunit vaccines
  • Toxoid vaccines
  • Conjugate vaccines
  • DNA vaccines
  • Recombinant vector vaccines

Among all these segments, sub-unit vaccine is the largest revenue generator, though synthetic vaccines, recombinant vector vaccines, and DNA vaccines are emerging as the fastest-growing segments.

The first vaccine of the world:

In 1796, Edward Anthony Jenner not only discovered the process of vaccination, alongside developed the first vaccine of the world for mankind – smallpox vaccine. To develop this vaccine Jenner acted upon the observation that milkmaids who caught the cowpox virus did not catch smallpox.

As per published data prior to his discovery the mortality rate for smallpox was as high as up to 35%. Thus, Jenner is very often referred to as the “Father of Immunology”, whose pioneering work has “saved more lives than the work of any other person.”

Later on in 1901 Emil Von Behring received the first Nobel Prize (ever) for discovering Diphtheria serum therapy.

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% cost of capital, the capitalized total R&D expenditure amounts to $ 474.88 million CAD.”

Issues and challenges:

To produce a safe and effective 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% of the production costs for 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. As a result, the key issue for developing a right type of newer vaccine will continue to be a matter of pure economics.

A great initiative called GAVI: 

Around 23 million children of the developing countries are still denied of important and life-saving vaccines, which otherwise come rather easily to the children of the developed nations of the world.

To resolve this inequity, in January 2000, the Global Alliance for Vaccines and Immunization (GAVI) was formed. This initiative was mainly aimed at generating sufficient fund to ensure availability of vaccines for children living in the 70 poorest countries of the world.

The GAVI Alliance has been instrumental in improving access to six common infant vaccines, including those for hepatitis B and yellow fever. GAVI is also working to introduce pneumococcal, rotavirus, human papilloma virus, meningococcal, rubella and typhoid vaccines in not too distant future.

In August 2013, GAVI has reportedly launched a campaign in Kenya to fight the world’s leading killer of children under five with a new Pneumococcal Vaccine for prevention from pneumonia, meningitis and sepsis, which kill more than half a million people a year.

GAVI hopes to avert 700,000 deaths by 2015 through the immunization of 90 million children with pneumococcal vaccines.

Global pharma majors Pfizer and GlaxoSmithKline (GSK) are producing the vaccines as a part of a deal part-funded by Britain, Italy, Canada, Russia, Norway and the Bill Melinda Gates Foundation.

Current trend in newer vaccine development:

Malaria Vaccine:

According to the National Institute of Health (NIH) of the United States, the results of an early-stage clinical trial published in August 8, 2013 in the ‘Journal Science’ for an investigational malaria vaccine has been found to be safe to generate an immune system response and to offer protection against malaria infection in healthy adults.

The scientists at Sanaria Inc., of Rockville, Md. Research Center developed this vaccine known as PfSPZ. The researchers reportedly found that injecting patients with live-but-weakened malaria causing parasites appeared to create a protective effect.

Earlier, Reuters on December 20, 2011 reported that the British scientists have developed an experimental malaria vaccine, which has the potential to neutralize all strains of the most deadly species of malaria parasite.

In October 2011, the data published for a large clinical trial conducted in Africa by GlaxoSmithKline on their experimental malaria vaccine revealed that the risk of children getting malaria had halved with this vaccine. Reuters also reported that other teams of researchers around the world are now working on different approaches to develop a malaria vaccine.

Tuberculosis vaccines:

The Lancet reported in March 2013, as BCG vaccination provides incomplete protection against tuberculosis in infants, a new vaccine, modified Vaccinia Ankara virus expressing antigen 85A (MVA85A), has been designed to enhance the protective efficacy of BCG. MVA85A was found well-tolerated and induced modest cell-mediated immune responses. However, the reasons for the absence of MVA85A efficacy against tuberculosis or M tuberculosis infection in infants would need exploration.

Universal Cancer vaccines:

In a breakthrough development, the Israeli company Vaxil BioTherapeutics has reportedly formulated a therapeutic cancer vaccine, now in clinical trials at Hadassah University Medical Center in Jerusalem.

If everything falls in place, the vaccine could be available about six years down the road, to administer on a regular basis not only to help treating cancer but also to keep the disease from recurring.

Though the vaccine is being tested against a type of blood cancer called multiple myeloma, if it works as the initial results indicate, its platform technology VaxHit could be applied to 90 percent of all known cancers, including prostate and breast cancer, solid and non-solid tumors.

HIV Vaccine:

A recent effort to find a vaccine for HIV is reportedly beginning in 2013 at laboratories in a London hospital and two centers in Africa. The work will be split equally between London, the Rwandan capital Kigali and Nairobi in Kenya.

It has been reported that scientists are recruiting 64 healthy adult volunteers for the trial, which is expected to take up to two years.

Vaccines 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.

India needs a vibrant vaccine business sector:

For 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 longer-term economic sustainability.

More often than not, these stakeholders find it difficult to deploy sufficient fund to take their vaccines projects successfully through various stages of clinical development in order to obtain marketing approval from the drug regulator, while registering a decent return on investments. This critical issue needs to be appropriately and urgently addressed by the Government to make the disease prevention initiatives in the country sustainable.

Changing market dynamics: 

Even in a couple of decades back, ‘Vaccines Market’ in India did not use to be considered as a focus area by many pharmaceutical companies. Commoditization of this market with low profit margin and unpredictable interest of the government/the doctors towards immunization were the main reasons. Large global players like Glaxo exited the vaccine market at that time by withdrawing products like, Tetanus Toxoid, Triple Antigen and other vaccines from the market.

Currently, the above scenario is fast changing. The vaccine market, as stated above, is getting rejuvenated not only with the National Immunization Program (NIP) of the country, but also with the emergence of newer domestic vaccines players and introduction of novel vaccines by the global players, which we shall discuss below.

In addition, the ‘Indian Academy of Pediatrics (IAP) Committee on Immunization’ now recommends the ‘best individual practices schedule’ for the children in consultation with their respective parents. Such schedule may not conform to NIP and include newer vaccines, broadening the scope of use of vaccines in general.

Global Market:

According to GBI Research Report, overall global vaccines market was valued at US$ 28 billion in 2010 and is expected to reach US$ 56.7 billion by 2017 with a CAGR of 11.5%. The key growth driver of this segment will be introduction of newer vaccines, which are currently either in the regulatory filing stage or in the late stages of clinical development.

The important international players in the vaccines market are GlaxoSmithKline, Sanofi, Pfizer, Novartis AG, Merck and SP-MSD. Together they represent around 88% of the total vaccine segment globally, the report highlights.

Indian Market:

McKinsey in its report titled, “India Pharma 2020: Propelling access and acceptance, realizing true potential“ stated that at 2% penetration, the vaccines market of India is significantly under-penetrated with an estimated turnover of around US$ 250 million, where the private segment accounts for two-thirds of the total. McKinsey expects the market to grow to US$ 1.7 billion by 2020.

India is one of largest markets for all types of vaccines in the world. The new generation and combination vaccines, like DPT with Hepatitis B, Hepatitis A and Injectable polio vaccine, are driving the growth. The demand for veterinary vaccines is also showing ascending trend. Pediatric vaccines contribute to around 60% of the total vaccines market in India.

Domestic Indian players like, Serum Institute, Shantha Biotecnics, Bharat Biotech and Panacea Biotech are poised to take greater strides in this direction. Bharat Biotech is incidentally the largest Hepatitis B vaccine producer in the world. Likewise, Serum Institute is reportedly one of the largest suppliers of vaccines to over 130 countries and claim that ’1 out of every 2 children immunized worldwide gets at least one vaccine produced by Serum Institute.’

The first new vaccine developed in India:

Indian scientists from Bharat Biotech Ltd in Hyderabad have reportedly developed a new oral vaccine against the Rotavirus induced diarrhea, where both vomiting and loose motion can severely dehydrate children very quickly. This is the first new vaccine developed in India, establishing itself as the first developing country to achieve this unique distinction.

Two recent vaccine JV and Partnership agreements in India:

British drug major GlaxoSmithKline (GSK) has reportedly agreed to form a 50-50 venture with the domestic Indian vaccine manufacturer Biological E Limited in January 2013 to develop a product that would combine GSK’s injectable polio shot with a vaccine produced by Biological E to protect against five diseases including diphtheria and tetanus.

In addition, MSD pharma of the United States and Indian drug major Lupin have announced a partnership agreement to market, promote and distribute, MSD’s 23-valent Pneumococcal Polysaccharide Vaccines under a different brand name in India for prevention of Pneumococcal disease, pneumonia being its most common form affecting adults.

A possible threat: 

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

The report predicts, the virtual monopoly that Indian vaccines 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 World Health Organization’s (WHO) ‘pre-qualification’ certification that allows it to approve locally manufactured vaccines to compete for UN tenders. 

Action areas to drive growth:

McKinsey in its above report ‘India Pharma 2020’ indicated that the action in the following 4 areas by the vaccine players would drive the vaccine market growth in India:

  • Companies need to go for local production of vaccines or leverage supply partnerships. MSD and GlaxoSmithKline’s local partnership in India and for the HiB vaccine with Bio-manguinhos in Brazil may be cited as examples.
  • Companies will need to conduct studies on the economic impact of vaccination and establish vaccine safety and performance standards.
  • Extension of vaccine coverage beyond pediatricians and inclusion of general practitioners, consulting physicians and gynecologists will be essential.
  • Companies will need to enhance supply chain reliability and reduce costs.

Conclusion: 

On January 7, 2012, while requesting the ‘Overseas Indian Medical Professionals’ to partner with the institutions in India, the Health Minister, in his address, announced that the Ministry of Health has already introduced the second dose of measles vaccine and Hepatitis-B vaccination across the country. Moreover, from December 2011 a ‘Pentavalent Vaccine’ has been introduced, initially in 2 States, covering 1.5 million children of India.

All these augur quite well for the country. However, keeping in view of the humongous disease burden of India, immunization program with various types of vaccines should receive active encouragement from the government as disease prevention initiatives, keeping the future generation in mind.

If vaccine related pragmatic policy measures, with equal focus on their effective implementation, are initiated in the country, without delay, the domestic vaccine market, in turn, will receive much awaited further growth momentum. Such initiatives together with newer foreign players and modern imported vaccines coming in, would help the country addressing effectively a prime healthcare concern of the country in a holistic way.

It is about time to aggressively garner adequate resources to develop more modern vaccines in the country, promote and implement vaccine awareness campaigns in the nation’s endeavor for disease prevention before they strike hard and at times fatally.

That said, taking available real world facts into account, doesn’t Dr. Gerhard Buchwald’s and today’s anti-vaccination lobbyists’ postulation, ‘Vaccination – A Business based on fear’, appear to be emanating from a self created world of doom and gloom, defying public health interest for effective disease prevention?

Slugfest in Pharma Land: Isn’t ‘The Pot Calling the Kettle Black?’

Posted on by

Close on the heels of detention of a British Citizen, an American citizen too has  been reportedly detained, for the first time, by the Chinese Government in connection with unfolding mega corruption scandal in the country’s pharma industry involving even ‘third party’.

A slugfest over this corruption scandal too has already begun. Media reports highlight, vested interests, as usual, retaliate by saying that China’s attention to the alleged corruption by MNCs is to benefit the local Chinese companies.

As per reports, big global pharma innovator companies like, GlaxoSmithKline, AstraZeneca and UCB are currently being questioned by the Chinese authorities related to this scam.

Critical role of ‘Third Party’ in pharma bribery and corruption: 

Although in the above Chinese scam, a third party, in form of a travel agency, has been accused to have played a critical role in the GSK case, it will be hard to believe that this is a solitary example.

Internal ‘Compliance Systems’ of global pharma companies, in most cases, are believed to be robust enough and will generally be found squeaky clean by any audit. Unfortunately, as it appears from various international reports, corruption still enters through cracks between seemingly robust ‘compliance firewalls’ for business gain.

Invariably in response, expensive and high decibel Public Relations (PR) machineries are put to overdrive. These extremely capable PR agents, with their  all guns blazing, keep trying to establish that such incidents, though quite frequent and are taking place across the world unabatedly, are nothing but  ‘small aberrations’ in pursuit of pharma ‘innovation’ for newer drugs just to benefit the patients.

As one understands from the GSK case, the ‘third party’ travel agent reportedly attempted to keep all transactions at arm’s length to avoid detection of any unholy nexus by the Chinese regulators. 

However, in the real world, it could possibly be any crafty and well-identified ‘third party’, intimately associated with the pharmaceutical business process. These ‘third parties’ are crafty enough to exploit the loopholes in the seemingly robust compliance systems of the concerned companies to help facilitating their financial performance. 

An interesting commonality in all such often repeated scams is the lack of top management accountability of the companies involved. This would probably surprise even the recent public sector scam tainted concerned ministers and top bureaucrats of India.

Much to everybody’s dismay, such incidents reportedly continue to take place in various parts of the world and in all probability in India too.

Other countries initiated probes:

Unlike the high-octane development in China, in many developed countries probes against such corruption have already been initiated at a different scale and level. For example, in Canada a conservative MP reportedly testified on October 17, 2012 to the ‘Standing Senate Committee on Social Affairs, Science and Technology’ as an expert witness regarding post-approval drug monitoring and the corrupt practices of pharmaceutical companies.

Global Corruption Barometer 2013:

When a person talks about corruption, it usually gets restricted to corrupt practices in the Public Sector. Any such issue involving Business, Healthcare, Education and even Judiciary, Media and NGOs are considered at best as misdemeanor, if not minor aberrations.

In this context it is worth mentioning that ‘Transparency International’ has released Global Corruption Barometer 2013 recently.  This ‘2013 Barometer’ is the world’s largest public opinion survey on corruption. It surveyed 114,000 people in 107 countries.

The reported global findings of this survey, which indicate a general lack of confidence in the institutions tasked to fight corruption, is as follows:

  • More than one in two people thinks corruption in their country has worsened in the last two years.
  • 54 per cent of people surveyed believe their governments’ efforts to fight corruption are ineffective.
  • 27 percent of respondents have paid a bribe when accessing public services and institutions in the last 12 months, revealing no improvement from previous surveys.
  • In 51 countries around the world, political parties are seen as the most corrupt institutions.
  • In 36 countries, people view the police most corrupt, in 20 countries they view the judiciary as most corrupt.
  • 54 percent of respondents think that the government in their country is run by special interests.

Situation alarming in India:

However, in India, the situation is much worse. Besides political parties, police and legislature, institutions like, Health Systems, Business, Judiciary, NGOs and even Media smack of high level of corruption, as follows:

No: Institutions Bribe Quotient %
1. Political Parties 86
2. Police 75
3. Legislature 65
4. Education 61
5. Health Systems 56
6. Business 50
7. Judiciary 45
8. Religious Bodies 44
9. Media 41
10. NGO 30
11. Military 20

Moreover, as per the report, approximately one out of four people paid a bribe globally in 2012, while in India, the bribe-paying rate was twice, with a little over one out of two people paying a bribe. Based on this indicator alone India occupies 94th rank out of 107 countries.

Coming back to healthcare in India, manifestations of high level corruptions in this critical area taken together with the same, as reported for its close connects like, as follows, are indeed alarming:

  • Business houses (include pharma companies)
  • Education (produces doctors, nurses etc.) 
  • Judiciary (also resolves various pharma disputes) 
  • Media (help creating unbiased public opinion) 
  • NGOs (takes care of Patients’ interest) 

The prevailing situation is highly disturbing, as any meaningful reform measures in the healthcare space of India could be effectively blunted, if not negated, by influencing related corrupt institutions.

It is important to note that bribery in the Indian healthcare sector was as rampant as Education and Judiciary in 2012, as follows:

No. Sector Bribe Paid in 2012 %
1. Police 62
2. Registry & Permits 61
3. Land 50
4. Utilities 48
5. Education 48
6. Tax Revenue 41
7. Judiciary 36
8. Health 34

Where there’s smoke, there’s fire:

All these numbers vindicate the well-known dictum ‘where there’s smoke, there’s fire’ for the healthcare sector, in general, and the pharmaceutical sector, in particular, of India.

Bribery and corruption appear to have emerged as the key compliance related issues in the pharma sector. A report indicates that this is mainly due to manipulable environment in the pharma industry, just like in many other sectors as mentioned above.

Such manipulations could range from influencing drug procurement prices in return for kickbacks, giving expensive freebies to the medical practitioners in return of specific drug prescriptions, and even making regional regulatory bodies to provide favorable reports overlooking blatant malpractices.

High level of tolerance:

KPMG Fraud Survey Report 2012 also highlights, though bribery and corruption continues to be an issue, pharma industry shows reluctance to discuss it openly. Moreover, close to 70 per cent of respondents surveyed said, they faced no significant threats from such issues.

The report also indicated, around 72 per cent of respondents expressed that their respective companies have in place a robust mechanism to address bribery and corruption. However, only few respondents expressed inclination to explain such in-house mechanisms. This vindicates the point of high levels of institutional tolerance to bribery and corruption in the pharmaceutical sector of India, just like in many other countries.

“Collusive nexus”:

Even a Parliamentary Standing Committee in its findings reportedly indicted India’s top drug regulatory agency for violating laws and collusion with pharmaceutical companies to approve medicines without clinical trials with the following remark:

“There is sufficient evidence on record to conclude that there is collusive nexus between drug manufacturers, some functionaries of CDSCO and some medical experts.”

A Research Scientist fumes:

Following is a reported comment of a research scientist on corruption and bribery in the pharmaceutical industry of India:

“It would not make me happy, to put it mildly, to think of a drug that I’d had a part in discovered being flogged via sleazy vacation offers and sets of cookware dumped on a doctor’s office floor.”

Where pharma and political slugfests unite:

This short video clip captures one of too many pharma slugfests given a very high level and fiery political dimension in the global pharma land.

Conclusion:

As we have seen in the ‘Global Corruption Barometer 2013’, the respondents regarded almost all key institutions and industrial sectors in India as being corrupt or extremely corrupt.

As per the above report, corruption seems to have engulfed the private sector too, and alarmingly has not spared even the ‘healthcare system’ at large , as it quite prominently shows up in the ‘Corruption Barometer 2013’. 

As deliberated above, some ‘third parties’ of any type, working within the pharmaceutical value chain, could well be the fountain heads of many types of corruptions, as reported in China. They should be put under careful vigil of the regulators, placed under magnifying glasses of scrutiny and the rogues must quickly be brought to justice wherever and whenever there are violations. A report stating, Chinese administration has decided to punish 39 hospital employees for taking illegal kickbacks from pharmaceutical companies as a part of country’s widening investigation against pharma corruption, would justify this point.

That said, the task in hand is much tougher. On the one hand an Indian Parliamentary Panel observes that both regulators and the pharma companies are hand in glove to fuel corruption, instead of dousing the fire.

On the other hand, the global pharma industry has been accusing the Indian government of ‘protectionism’, ‘lack of transparency/predictability in its policy measures’ and ‘draconian IP laws’.

In the midst of all these cacophony, haven’t the stakeholders and the public at large, with exposure to contextual information, started pondering:

Gosh! in the slugfest on the pharma land, isn’t ‘The Pot Calling the Kettle Black?’

Balancing IPR with Public Health Interest: Brickbats, Power Play and Bouquets

Posted on by

It is now a widely accepted dictum that Intellectual Property Rights (IPR), especially pharma patents, help fostering innovation and is critical in meeting unmet needs of the patients.

However, the moot question still remains, what type pharmaceutical invention, should deserve market exclusivity or monopoly with overall freedom in pricing, keeping larger public health interest in mind.

In line with this thinking, for quite sometime a raging global debate has brought to the fore that there are quite a large number of patents on drug variants that offer not very significant value to the patients over the mother molecules, yet as expensive, if not more than the original ones. In common parlance these types of inventions are considered as ‘trivial incremental innovations’ and described as attempts to ‘evergreening’ the patents.

The terminology ‘evergreening‘ usually ‘refers to a strategy employed by many pharmaceutical companies to extend their market monopoly by slightly changing the existing molecules and obtaining new patents to continue to enjoy market exclusivity and pricing freedom, which otherwise would not have been possible.

Path breaking or jaw-drooping ‘W-O-W’ types of innovations are not so many. Thus most of the patented drugs launched globally over the last several decades are indeed some sort of ‘me-too drugs’ and generally considered as ‘low hanging fruits’ of R&D, not being able to offer significantly greater value to patients than already exiting ones. Many of these drugs have also achieved blockbuster status for the concerned companies, backed by high voltage marketing over a reasonably long period of time. It is understandable, therefore, that from pure business perspective why serious global efforts are being made to push the same contentious system in India too.

Example of some of these molecules (not necessarily in the written order), are as follows:

  • Cemetidine – Ranitidine – Famotidine – Nizatidine – Roxatidine (to treat Acid-peptic disease)
  • Simvastatin – Pravastatin – Lovastatin – Pitavastatin – Atorvastatin – Fluvastatin – Rosuvastatin (to treat blood lipid disorder)
  • Captopril – Enalepril – Lisinopril – Fosinopril – Benzapril – Perindopril – Ramipiril – Quinalapril – Zofenopril (Anti-hypertensives)

However, pharmaceutical companies do argue that such ‘incremental innovations’ are the bedrock for growth of the pharmaceutical industry and are essential to continue to fund pharmaceutical research and development.

An interesting paper:

A paper titled, “Pharmaceutical Innovation, Incremental Patenting and Compulsory Licensing” by Carlos M. Correa argued as follows:

  • Despite decline in the discovery of New Chemical Entities (NCEs) for pharmaceutical use, there has been significant proliferation of patents on products and processes that cover minor, incremental innovations.
  • A study conducted in five developing countries – Argentina, Brazil, Colombia, India and South Africa has:
  1. Evidenced a significant proliferation of ‘ever-greening’ pharmaceutical patents that    can block generic competition and thereby limit patients’ access to medicines.
  2. Found that both the nature of pharmaceutical learning and innovation and the interest of public health are best served in a framework where rigorous standards of inventive step are used to grant patents.
  3. Suggested that with the application of well-defined patentability standards, governments could avoid spending the political capital necessary to grant and sustain compulsory licenses/government use.
  4. Commented, if patent applications were correctly scrutinized, there would be no need to have recourse to CL measures.

A remarkable similarity with the Indian Patents Act:

The findings of the above study have a striking similarity with the Indian Patents Act. As per this Act, to be eligible for grant of patents in India, the pharmaceutical products must pass the ‘two-step’ acid test of:

  • Following the inventive step: Defined under Section 2(ja) of the Patents Act as follows:

“Inventive step” means a feature of an invention that involves technical advance as compared to the existing knowledge or having economic significance or both and that makes the invention not obvious to a person skilled in the art.

  • Passing scrutiny of Section 3(d) of the law: It categorically states, inventions that are a mere “discovery” of a “new form” of a “known substance” and do not result in increased efficacy of that substance are not patentable.

Supreme Court of India clarifies it:

The Honorable Supreme Court of India in page 90 of its its landmark Glivec judgement has clearly pronounced that all ‘incremental innovations’ may not be trivial or frivolous in nature. However, only those ‘incremental innovations’, which will satisfy the requirements of both the above Sections of the Act, wherever applicable, will be eligible for grant of patents in India. 

An opposite view:

Another paper presents a different view altogether. It states that incremental improvements on existing drugs have great relevance to overall increases in the quality of healthcare.

With the progress of the pharmaceutical industry, such drugs have helped the physicians to treat diverse group of patients. They also represent advances in safety, efficacy along with newer dosing options significantly increasing patient compliance.

The paper claims that ‘even from an economic standpoint, expanding drug classes represent the possibility of lower drug prices as competition between manufacturers is increased’.  It states that any policy aimed at curbing incremental innovation will ultimately lead to a reduction in the overall quality of existing drug classes and may ultimately curb the creation of novel drugs.

Pricing:

Experts, on the other hand, argue, if patents are granted to such ‘incremental innovations’ at all, their prices need to be determined by quantifying ‘Incremental Value’ that patients will derive out of these inventions as compared to the generic versions of respective original molecules.

Use of such drugs may lead to wasteful expenditure:

A large majority of stakeholders also highlight, though many of such drugs will have cheaper or generic alternatives, physicians are persuaded by the pharma players to prescribe higher cost patented medicines with the help of expensive avoidable marketing tools, leading to wasteful expenditure for all. The issue of affordability for these drugs is also being raised, especially, in the Indian context.

  • The ‘2012 Express Scripts Canada Drug Trend Report’ unfolded that the use of higher-cost medications without offering additional patient benefits resulted in waste of $3.9 billion annually in Canada.
  • Another recent Geneva-based study concluded as follows:

“Evergreening strategies for follow-on drugs contribute to overall healthcare costs. It also implies that policies that encourage prescription of generic drugs could induce saving on healthcare expenditure. Healthcare providers and policymakers should be aware of the impact of evergreening strategies on overall healthcare costs.”

  • Some other studies reportedly revealed, “Medicines sold in France are 30 times more expensive than what it costs pharmaceutical companies pay to manufacture them.” Industry observers opine, if that is happening in France what about India? Quoting experts the same report comments, “If pharmaceutical companies are forced to follow moral and human values, it could save the tax payer at least 10 billion euros, an amount which could fill up the deficit of the national health care system.”
  • Yet another article questioned, “What if a physician is paid speaking or consulting fees by a drug maker and then prescribes its medicine, even if there is no added benefit compared with cheaper alternatives?”

More debate:

According to a paper titled, ‘Patented Drug Extension Strategies on Healthcare Spending: A Cost-Evaluation Analysis’ published by PLOS Medicine, European public health experts estimate that pharmaceutical companies have developed “evergreening” strategies to compete with generic medication after patent termination. These are usually slightly modified versions of the existing drugs.

Following are some brands, which were taken as examples for evergreening:

S.No.

Evergreen

Medical Condition

Original Brand

1.

 Levocetirizine (Vozet) Allergies Cetirizine (Zyrtec)

2.

 Escitalopram (Lexapro) Depression Citalopram (Celexa)

3.

 Esomeprazole (Nexium) Acid reflux Omeprazole (Prilosec)

4.

 Desloratadine (Clarinex) Allergies Loratadine (Claritan)

5.

 Zolpidem Extended Release (Ambien CR) Insomnia Zolpidem (Ambien)

6.

 Pregabalin (Lyrica) Seizures Gabapentin (Neurotonin)

Source: Medical Daily, June 4, 2013

In this study, the researchers calculated that evergreening – where pharmaceutical companies slightly modify a drug molecule to extend its patent, had cost an extra 30 million euros to the healthcare system in Geneva between 2000 and 2008. The authors argue that ‘evergreening’ strategies, “more euphemistically called as ‘life cycle management’ are sometimes questionable benefit to society.”

As the paper highlights, in this scenario the companies concerned rely on brand equity of the original molecule with newer and more innovative marketing campaigns to generate more prescriptions and incurring in that process expenses nearly twice as much on marketing than on research and development.

Brickbats:

In this context, recently a lawmaker rom America reportedly almost lambasted India as follows:

“I’m very concerned with the deterioration in the environment for protection of US intellectual property rights and innovation in India. The government of India continues to take actions that make it very difficult for US innovative pharmaceutical companies to secure and enforce their patents in India.“ 

On this, the Indian experts comment, if the situation is so bad in India, why doesn’t  America get this dispute sorted out by lodging a formal complaint against India in the WTO, just as what India contemplated to do, when consignments of generic drugs of Indian manufacturers were confiscated at the European ports, alleging those are counterfeit medicines.

Yet another recent news item highlighted a “concerted effort, which involves letters from US corporations and business groups to the president, testimony by Obama administration officials before Congress, and lawmakers’ own critiques, came ahead of US secretary of state John Kerry’s trip to India later this month (has already taken place by now) for the annual strategic dialogue, which will precede Prime Minister Manmohan Singh’s visit to Washington DC in September.”

The report stated, the above letter complained that over the last year, “courts and policymakers in India have engaged in a persistent pattern of discrimination designed to benefit India’s business community at the expense of American jobs … Administrative and court rulings have repeatedly ignored internationally recognized rights — imposing arbitrary marketing restrictions on medical devices and denying, breaking, or revoking patents for nearly a dozen lifesaving medications.” 


At a recent Congressional hearing of the United States, a Congressman reportedly expressed his anger and called for taking actions against India by saying,

“Like all of you, my blood boils, when I hear that India is revoking and denying patents and granting compulsory licenses for cancer treatments or adopting local content requirements.”

Indian experts respond to these allegations by saying, patent disputes, patent challenges, revocation of patents, compulsory licensing etc. are all following a well-articulated judicial process of the country, where Indian government has hardly any role to play or intervene. American government and lawmakers are also expected to respect the rule of law in all such cases instead of trying to denigrate the Indian system.

The Power Play:

This short video clipping captures the Power Play in America on this matter.

The Government of India responds:

Ministry of Commerce and Industries of India reportedly countered the allegations of the United States over patents to the US Trade Representive arguing that the Indian IPR regime is fully TRIPS-compliant and Indian Patents Act “encourages genuine innovation by discouraging trivial, frivolous innovation, which leads to evergreening”.

Countries adopting the Indian model:

The above report also highlighted as follows:

  • Argentina has issued guidelines to reject ‘frivolous’ patents.
  • Peru, Columbia, other South American countries have placed curbs.
  • Philippines has similar provisions.
  • Australia is contemplating making the law tougher.

Revised report of Dr. R. A. Mashelkar Committee:

Even the revised (March 2009) ‘Report of the Technical Expert Group (TEG) on Patent Law Issues’, the TEG, chaired by the well-known scientist Dr. R.A. Mashelkar, in point number 5.30 of their report recommended as follows:

“Every effort must be made to prevent the practice of ‘evergreening’ often used by some of the pharma companies to unreasonably extend the life of the patent by making claims based sometimes on ‘trivial’ changes to the original patented product.  The Indian patent office has the full authority under law and practice to determine what is patentable and what would constitute only a trivial change with no significant additional improvements or inventive steps involving benefits.  Such authority should be used to prevent ‘evergreening’, rather than to introduce an arguable concept of ‘statutory exclusion’ of incremental innovations from the scope of patentability.”

Bouquets:

As stated above, many experts across the world believe, the criticism that Section 3 (d) is not TRIPS Agreement compliant is unfounded, as no such complaint has been lodged with the World Trade Organization (WTO) in this matter, thus far. The safeguards provided in the patent law of India will help the country to avoid similar issues now being faced by many countries. Importantly, neither does the section 3(d) stop all ‘incremental innovations’ in India.

Quoting a special adviser for health and development at South Centre, a think tank based in Geneva, Switzerland, a recent report indicated, “Many developing countries will follow India’s example to protect the rights of their populations to have access to essential medicines”.

Yet another report quoting an expert articulates, “India’s top court’s decision affirms India’s position and policy on defining how it defines inventions from a patenting point of view for its development needs. It challenges the patenting standards and practices of the developed countries which are the ones really in much need of reform.”

The Honorable Supreme Court in its Glivec judgment has also confirmed that such safeguard provisions in the statute are expected to withstand the test of time to protect public health interest in India and do not introduce any form of unreasonable restrictions on patentability of drug inventions.

Conclusion:

Not withstanding the report of the US-India Business Council (USIBC) titled ‘The Value of Incremental Innovation: Benefits for Indian Patients and Indian Business’, arguing for abolition of section 3(d) of the Indian Patents Act to pave the way for patentability for all types of incremental innovations in pharmaceuticals, realistically it appears extremely challenging.

As the paper quoted first in this article suggests, denial of patents for inventions of dubious value extending effective patent period through additional patents, is a significant safeguard to protect public health interest. This statutory provision will also pave the way for quick introduction of generics on expiry of the original patent.

Taking all these developments into active consideration, keen industry watchers do believe, for every effort towards balancing IPR with Public Health Interest, both brickbats and bouquets will continue to be showered in varying proportion together with the mounting pressure of power play, especially from the developed world and still for some more time.

However, in India this critical balancing factor seems to have taken its root not just deep and strong, but in all probabilities - both politically and realistically, the law is now virtually irreversible, come what may.

New ‘Patient Compensation’ Norms on Clinical Trials in India: Overdue Action, Sharp Reaction and Ethical Issues

Posted on by
Reply

Responding to the damning stricture made by the Supreme Court on January 3, 2013, the Ministry of Health, as expected, by a gazette notification of January 30, 2013 has made the norms of compensation to patients participating in Clinical Trials (CT) more stringent.

‘Patient Compensation’ will now include injury or death, even if those are not related to the drugs being tested in the CT.

It is worth mentioning that these guidelines have been reportedly worked out after due consideration of around 300 comments received from the stakeholders on the draft proposal circulated by the Ministry of Health in July 2011, couple of rounds of discussion with the members of the civil society, expert groups and against reported ‘stiff opposition from the drug companies’.

Just a day after, on February 1, 2013, the Ministry of Health also notified final regulations on the conditions under which CT sites will be authorized by the local licensing and the inspection authorities of the Central Drugs Standard Control Organization (CDSCO).

Key features of the new Government ‘Action’ on patient compensation:

Following are the key features in the new norms for patient compensation:

1. The sponsors of CTs will now be liable for injuries or deaths, which will take place during the course of a clinical trial and will be required to pay compensation to the patients or their families.

2. The investigator of the CT must inform the concerned pharmaceutical company, the Clinical Research Organization (CRO) and the Ethics Committee regarding injury or death during CT within 24 hours.

3. It will be mandatory for all CT Ethics Committees to be pre-registered with the Drug Controller General of India (DCGI), unlike the old system where this was not required and trial sponsors reportedly could staff the committee.

4. The pharmaceutical companies and the CROs will get 10 days time to submit a detailed report on related serious adverse event to the Ethics Committee, which in turn will get another 10 to 11 days to convey its evaluation on compensation to be paid to the independent expert committee. The Expert Panel will then advise the DCGI of an appropriate financial compensation within 30 days from the date of receiving the above report.

5. It will no longer require inclusion of specific amount of compensation for injury or death in the informed consent form and does not refer to insurance coverage for potential liability.

6. It requires the sponsors of CTs to provide the trial subject with free “medical management” for as long as it will require.

Will make CT more expensive in India:

Clinical Trials (CT), as we know, are of critical importance for obtaining marketing approval of any new drug and at the same time forms a major cost component in the new drug development process, across the world.

Any savings in this area, both in terms of time and money, will add significantly to the profit margin of the product. In that context the above notification will now make CT more expensive in India.

Sharp ‘reaction’ of CT related industry:

Understandably, reacting to this notification, some Clinical Research Organizations have expressed concerns in areas like:

  1. Lack of distinction between study-related injuries and non-study related injuries
  2. The use of placebos in placebo-controlled trials,
  3. Lack of any arbitration mechanism in case of disagreement on causality/quantum of compensation and the lack of clarity on who constitutes the Expert Committee and its composition.

Some other Experts related CT industry do highlight a few more troubling issues in the notification, as follows:

1. Compensation to be paid for ‘failure of an investigational product to provide intended therapeutic effect.’ This, they expressed, is intriguing as the very nature of a CT is to ascertain whether the investigational drug is efficacious or not.

2. If compensation is not paid as required, a sponsor or CRO may be banned from conducting any further trials in the country. This, they feel, provision could make India a challenging place to conduct CT.

3. There should also be clarity on the formula to determine compensation, the process for determining a compensation amount, and how an appeal process would work.

The bottom-line is, due to this new policy on ‘Patient Compensation’ CT expenses may go up considerably in India.

Other expert views:

On the other hand, some other experts opined to the International Weekly Journal on Science – ‘nature’ as follows:

“These reforms should go further to restore public confidence and the Indian government should establish special courts to deal quickly with allegations of medical misconduct, such as not fully disclosing to participants the risks involved in a clinical trial”.

Global concern on ethical issues with ‘Placebo Controlled’ studies:

In this context, though issues related to ‘Placebo Controlled’ trials have been raised by the CT related industry in India, very interestingly a paper of Research Administration of the University of California on the ethical issues with ‘Placebo Controlled’ studies’ clearly articulates that the use of a placebo in clinical research has remained a contentious issue in the medical community since long.

Some strongly argue that use of placebos is often unethical because alternative study designs would produce similar results with less risk to individual research participants. Others argue that the use of placebos is essential to protect society from the harm that could result from the widespread use of ineffective medical treatment.

However, as per the Office for Human Research Protections (OHRP) guidebook, “Placebos may be used in clinical trials where there is no known or available (i.e. US-FDA-approved) alternative therapy that can be tolerated by subjects.”

This issue also needs to be deliberated and effectively addressed by the Indian drug regulator in the debate of patient compensation for ‘placebo controlled trials’.

A perspective on CT in India:

Interestingly, in this critical area India is fast evolving as a major hub. This is vindicated by a study conducted by Ernst & Young and the Federation of Indian Chambers of Commerce and Industry of India (FICCI), which states that India now participates in over 7 per cent of all global phase III and 3.2 per cent of all global phase II trials. The key points of attraction of the global players, so far as India is concerned, were reported as follows:

1. Cost of Clinical Trial (CL) is significantly less in India than most other countries of the world

2. Huge patient pool with different disease pattern and demographic profile

3. Easy to enroll volunteers, as it is easy to persuade poor and less educated people as ‘willing’ participants.

Such opportunities, experts believe, should have ideally made the clinical research industry to demonstrate greater responsibility to ensure that patients’ safety needs are adequately taken care of. Unfortunately, despite such expectations, some important areas like ‘patient compensation’ have still remained blatantly neglected.

It has now come to light with the help of ‘Right To Information (RTI)’ query that more than 2,000 people in India died as a result of Serious Adverse Events (SAEs) caused during drug trials from 2008-2011 and only 22 of such cases, which is just around 1 percent, received any compensation. That too was with a meager average sum of around US$ 4,800 per family.

It has been widely reported that pharmaceutical companies often blame deaths that occur during trials on a person’s pre-existing medical condition and not related to CT.

DCGI had hauled-up 9 companies for blatant negligence:

According to another report quoting the Drug Controller General of India (DCGI), 25 people died in clinical trials conducted by nine pharmaceutical companies, in 2010. Unfortunately, families of just five of these victims received” compensation for trial related death, which ranged from Rs 1.5 lakh (US$ 3000) to Rs 3 lakh (US$ 6000).

This report also highlighted that arising out of this critical negligence, for the first time ever, the then DCGI was compelled to summon these nine pharmaceutical companies on June 6, 2011 to question them on this issue and with a clear directive to pay up the mandatory compensation for deaths related to clinical trial by June 20, 2011, or else all other CTs of these nine companies, which were ongoing at that time or yet to start, will not be allowed.

The report also indicates that after this ultimatum all the nine companies as mentioned therein had paid the compensation to the families of the patients who had died related to the CT.

Long exploitation of the fragile CT regulations in India:

For all these reasons, the subject of CT in India has created a huge ruckus, mainly for wide spread alleged malpractices, abuse and misuse of fragile CT regulations of the country by some players in this field. The issue is not just of GCP or other CT related standards but more of ethical mind-set and reported rampant exploitation of uninformed patients, especially in case of trial related injuries or even death.

The Bulletin of the World Health Organization (WHO) in an article titled, “Clinical trials in India: ethical concerns” reported as follows:

“Drug companies are drawn to India for several reasons, including a technically competent workforce, patient availability, low costs and a friendly drug-control system. While good news for India’s economy, the booming clinical trial industry is raising concerns because of a lack of regulation of private trials and the uneven application of requirements for informed consent and proper ethics review.”

“Pharmaceutical industry seeks to run studies in countries with lower costs”:

There seems to be nothing basically wrong in this approach per se. However, a recent report does highlight as follows:

“Clinical trials conducted by global drug makers and their proxies have generated increased scrutiny in recent years as the pharmaceutical industry seeks to run studies in countries with lower costs and populations where patients are not exposed to as many medications that can confound results. India has been a prime example”.

A lesson to learn by the Indian Drug Regulator:

It is worth noting that US-FDA in a communication meant for the consumers has stated as follows:

“The Food and Drug Administration’s job is to make sure medical treatments are safe and effective for people to use. FDA staff members meet with researchers, and perform inspections of clinical trial study sites to protect the rights of participants and to verify the quality and integrity of the data.”

The above approach seems to be drastically missing with the drug regulator in India as on date.

Conclusion:

Over a long period of time, a blatant negligence on reasonable care and financial compensation was allowed to continue by the Drug Regulator and the sponsors alike on the CTs conducted in India. A perceptible intent of justice to the patients, with the enforcement of stricter compensation laws and regulations for CT though belated, could dramatically change the CT scenario in India for the better in the years ahead.

In the fine balance of national priority for this area, patients’ safety and interest, I reckon, should always weigh more than the possibility of increase in the costs of CT in India. Thus,  the new norms of Patient Compensation indeed bring with it a breath of fresh air for the concerned stakeholders.

That said, the lose knots in some areas of the new norms, as discussed above, must be properly addressed and adequately tightened for greater clarity of the CT process, for all concerned.
