Changing Doctors’ Practice Dynamics With Covid-19 And Beyond

Unexpectedly, the answer to an onerous question surfaced just around a year’s time. In my article on this blog, written on April 08, 2019, I raised a question – “Would ‘Connected Healthcare’ Catch Pharma Players Off-Guard?” Interestingly, an unexpected and abrupt turn of events in the global healthcare space, including India, triggered by Covid-19 pandemic, signals an early dawn of an evolving reality, related to ‘Connected Healthcare’, in India.

Never ever, I reckon, the Government realized so well that continuation with a fragile public healthcare infrastructure is self-defeating for the country. Allocation of financial resources, at least 2.5 percent of the country’s GDP, for its rejuvenation – powered by AI-based modern digital technology, would help avoid overburden on the healthcare system. This will mean, saving more lives and also a significant reduction of morbidity, especially in a situation, like Covid-19 pandemic. Good health can propel good economy, more effectively.

That’s why, ‘connected healthcare’ – by effectively linking requisite ingredients of all health-related information that medical professionals and the patients would need, appears to be the new reality. This process is being facilitated by rapid acceleration of usage of various digital platforms, by both healthcare consumers and providers. Thus, it is becoming increasing clear now that leveraging digital technology with innovative mindset and a fresh pair of eyes, will be the way forward, in India, as well. It seems very likely, when considered from two angles:

  • What several research data reveals about an increase in usage of digital platforms by healthcare consumers and providers, before and during Covid-19 pandemic. Especially because, this struggle appears to be for a long haul.
  • Most countries are currently struggling to navigate through highly contagious Covid-19 outbreak and simultaneously trying to chart a workable pathway for avoiding similar eventualities in the future.

In this article, I shall try to focus on Covid-19 induced changes in doctors’ practice dynamics – based on research studies, while revisiting the subject on ‘connected healthcare,’ and its relevance now – also in the years ahead.

Research studies capture a new and growing awareness: 

The recent findings from the “Digital Doctor 2020” survey, which is a ‘21-country study of Doctors’ perspectives on digital and connected health, highlight some interesting points. This study was conducted just before the global outbreak of Coronavirus. Some of its findings were also deliberated inan article published in the PharmExec.com on April 23, 2020. The paper is titled, ‘How Prepared Were Physicians for the COVID-19 Digital Upswing? Some of the key points, as reported, are worth noting:

  • Although, the awareness of drug prescribers of different digital technologies related to healthcare is high, how these technologies work in healthcare was unknown to many doctors at the time of the Digital Doctor 2020 survey. It came out that clear benefit statements, will be welcomed when there is such a steep learning curve.
  • Regardless of face-to-face interactions still remaining preferred choice before the pandemic, online channels are on the rise and accelerating with COVID-19 lockdown.
  • Benefits of using connected health devices for patient management and treatment are widely recognized and is believed to play a key role in the future. The respondents agree, even their patients are now more interested in their own health data, as they are gaining control over their weight, diet and physical activities.

Highlighting that their research data over the last few weeks showing increasing usage of digital solution to respond and adapt to the new realities of Covid-19 pandemic, the author of the article concluded: ‘For a long time, digital solutions have often been considered an option; now they have become a necessity.’ To understand the emerging scenario, let us now look at the preferred communication channels of the doctors – pre-Covid-19 outbreak. 

Preferred channels of doctors pre-Covid-19 outbreak:

According to the Ipsos survey of pre-Covid-19 outbreak, face-to-face communication with Medical Representatives (MR) used to be the most favored channel of the doctors, as follows:

Channel Med. Rep Speaker Program Conf. E-detail Journal Ads Med. Liaison E-mail Direct mail Pharma website
Pref. % 35.2 11.7 10.0 8.4 8.4 8.8 8.4 5.0 4.1

However, on April 14, 2020, Ipsos shared the results of their interim research conducted, together with M360, among doctors, conducted during Coronavirus outbreak. The preliminary findings indicate, Covid-19 will permanently alter physician practice dynamics. A clear shift in the engagement model with them – away from in-person detailing, throws several significant questions on the traditional physician engagement template of the pharma players.

It also signals another fundamental change in the physicians’ practice dynamics, as Covid-19 seems to have changed practicality of having face-to-face communication between the representatives and doctors, as before. This situation makes ‘connected healthcare’ a reality – as we move deeper into the everyday- evolving scenario.

Some unexpected and significant changes surfaced in a month: 

The above research also flagged, the following two important changes, among several others, triggered by the Coronavirus outbreak:

  • The mean number of sales representative visits dropped from 15.7 before the Coronavirus outbreak to 1.3 in just the following month, during the pandemic 
  • Overall preference and effectiveness of e-detailing also improved, significantly, where any non-personal communication and interaction with drug companies, either through sales representatives or by others, were considered as e-detailing. 

This brings me back to the question, how are doctors feeling about this never before shift in their practice dynamics?

How are doctors feeling about a never before shift in their practice dynamics?

The ongoing research on this critical area captures a new reality, where many doctors, especially those who are not directly engaged in combating the Covid-19 pandemic, are clearly feeling a shift in their practice dynamics. Curiously, the new feeling of a shift also includes, the way these doctors interact with different drug companies, mostly through their Medical Representatives.

These inklings of the doctors are expected to get translated into some fundamental changes in the real-life situation, as we all sail through the life-changing time caused by Covid-19. Especially, considering the requirements of a new normal – social distancing, wearing a mask always while on outdoor, and several other norms as prescribed from time to time.

‘Connected healthcare,’ is expected to take its place on the center stage:

In this situation, ‘connected healthcare,’ which used to be more discussed than practiced, is expected to take its place on the center stage. It is necessary in the present situation for remote consultations, primarily for chronic ailments – for effective disease management and treatment. More so, as in the current situation individual health awareness of a large population, even in India, is increasing with an accelerated speed, perhaps more than ever before.

Thus, this is the right time to focus on ‘connected healthcare’, powered by AI-based digital technology. It has immense potential to help the Indian population getting immediate medical attention at a lower cost, with an improved access, for all. Though these are early days, it appears the ball has started rolling in the right direction, as the recent draft guidelines of the Indian Council of Medical Research (ICMR) indicates: ‘Patient can WhatsApp, SMS or email consent for Covid-19 clinical trials.’

Conclusion:

Still today, there is no sign of even temporary flattening the disease progression curve in India. As on May 10, 2020 morning, the recorded Coronavirus cases continue to climb sharply to 62,939 with 2,109 deaths, which is rising in India faster than most other countries. On May 07, 2020, AIIMS director again warned that Covid-19 pandemic is yet to peak in the country. “According to modeling data and the way our cases are increasing, it is likely that peak can come in June and July,” he added.

But is it getting worse? Despite stringent lockdown, there has been a surge in cases, which can also be attributed to higher levels of testing. However, from a doubling rate of 11.5 days on May 3, it has shortened to 10.3 days, which means that cases are doubling in quicker time. Each set of 10,000 cases is now increasing at a more rapid pace than the preceding set, highlighted an editorial of a leading news daily.

With a vaccine still elusive, the government had been banking mostly on the lockdown to break the chain of transmission of the virus. Meanwhile, the World Health Organization (WHO) has said: ‘Deliberately infecting healthy people with Coronavirus may speed Covid vaccine studies,’ reflecting more uncertainties in this area. It is also not likely that the country will cease to have any problems with its fragile public healthcare infrastructure and delivery system, even after flattening the disease progression curve.

Along with many other Covid-19 induced life-impacting changes, doctors’ practice dynamics are also expected to undergo a metamorphosis, lasting for an indefinite period. Consequently, I reckon, it’s about time, even for the pharma industry to voluntarily adopt ‘connected healthcare’ as a future way of life. One can get a glimpse of it in the Covid-19 clinical trial draft guidelines of the ICMR. Nonetheless, ‘connected healthcare’ comes with a clear signal of reducing the cost of healthcare and improved patient access, having the potential to effectively mitigate a sizeable part of the precipitated healthcare crisis, caused by Coronavirus.

Antimicrobial Resistance: A Recent Perspective

Posted on by
Reply

On January 23, 2018, at the World Economic Forum in Davos, Switzerland – the first independent analysis of pharmaceutical industry efforts to tackle antibiotic drug resistance, was published by the Netherlands based Access to Medicine Foundation.

The issue of Antimicrobial Resistance (AMR) was brought under focus by the World Economic Forum (WEF) not for the first time at Davos in 2018. Its 2013 Annual Report on global risks, also underscored the gargantuan health hazard that AMR poses to mankind. It said, we live in a bacterial world where we will never be able to stay ahead of the mutation curve. A test of our resilience is how far the curve, we allow ourselves to fall behind. It’s indeed a profound statement!

In that sense, the AMF analysis is important. More so, when the global population is virtually at the threshold of facing a situation very similar to pre-antibiotic era, where even a common infection used to pose threat to a life. And now, a fast-developing AMR to many effective antibiotics or even super-antibiotics, are making them almost redundant in many serious conditions. Consequently, around 700,000 people die every year only due to antimicrobial resistance, the world over.

The World Health Organization (WHO) also reiterated its grave concern in this area by a news release on September 20, 2017. It cautioned, “Antimicrobial resistance is a global health emergency that will seriously jeopardize progress in modern medicine.” Against that backdrop, in this article, I shall dwell on some latest developments in this area, both globally and also in India.

Dire need for newer antibiotics – but dry R&D pipeline:

At the very outset, let me flag another critical area that is intimately related to this concern. An article titled, “Where Are the Antibiotics?”, published by the AARP Foundation adds more to this growing concern. It writes, in an era when many breakthrough innovative drugs are curing some of our most deadly afflictions, the quest for meeting the unmet medical needs, seems to have shifted away from development of critically needed breakthrough antibiotics to effectively address AMR, for various reasons.

The author further highlighted that between the time penicillin was discovered in 1928, and the 1970s – 270 antibiotics were approved – a robust arsenal of powerful drugs that kept almost all bacterial infections at bay. However, since then, research into new antibiotics has declined dramatically. Today, just five of the top 50 big drug companies are reportedly developing innovative antibiotics – the article reiterates.  Nevertheless, some recent developments in this area can’t be ignored, either, which I shall touch upon in this discussion.

Global initiatives for a multi-pronged concerted action:

It is understandable that there are no magic bullets to address the fast-growing menace of AMR. It calls for a multi-pronged strategy with well-orchestrated concerted efforts for its effective implementation with military precision. Following are the three primary constituents who should lead from the front in the battle against AMR, as I reckon:

  • The world leaders
  • Each country, individually
  • Pharmaceutical industry, both global and local

The medical profession, including hospitals, nursing homes, the retail chemists and individual patients, also play a significant role to alleviate this problem, especially in India and other developing countries. But, I shall keep that as a subject for a separate discussion, altogether. Let me now touch-upon the first three constituents, one by one, as follows:

1. The world leaders’ initiative:

Realizing that failure to act on AMR will result in a global health and financial crisis, the world leaders met to address this growing menace. Accordingly, on September 21, 2016, the United Nations General Assembly (UNGA) passed a declaration aimed at slowing the spread of antibiotic-resistant superbugs. At this meeting in New York City, the top UN leaders successfully urged all governments to sign a political declaration to tackle the problem of AMR, both globally and in their respective countries. The joint declaration requires each country to develop a 2-year plan to protect the potency of antibiotics for both livestock and humans. The progress of the initiative for each country at the end of those 2 years will be evaluated. However, in this article, I shall focus only on the agreed human-specific actions, which include the following:

  • Antibiotics should be prescribed only when they are absolutely necessary
  • A massive education campaign about antibiotic resistance.
  • Greater monitoring of superbugs to understand the scope and magnitude of the problem.
  • Safeguarding current antibiotic stockpile.

The leaders suggested that people should be encouraged to help prevent the crisis from turning into a death sentence for millions, with the steps, such as:

  • Get available vaccines to prevent illness
  • Stop asking doctors for antibiotics when they have the cold or flu, as antibiotics treat neither
  • To urge their political leaders to commit to action in combating antibiotic resistance.

2. Country-specific initiatives:

In September 2016, just a year after the UNGA high-level meeting on AMR, an update by the United Nations Foundation reported that 151 countries out of 195 WHO member states have responded. The overall response includes the following, among others:

  • 85 percent of countries are developing or have developed National Action Plans (NAC).
  • 52 percent of countries have a fully developed plan with ‘One Health’ approach that seeks to unify human and veterinary medicine, agriculture, and food providers against the progression of AMR by reducing agricultural antimicrobial use.
  • 52 percent of Low and Middle-Income Countries (LMICs) have national-level measures in place on ‘Infection Prevention and Control (IPC)’ measures in human healthcare.

3. Pharmaceutical industry initiatives: 

I shall cite only the latest commendable developments in this area, as I see it. On Jan. 21, 2016 a document titled the ‘Declaration on Combating Antimicrobial Resistance’, was launched, again, as part of the World Economic Forum at Davos, Switzerland.

For the first time, 85 pharmaceutical, biotechnology, generic-drug, and diagnostic companies agreed on a common set of principles for global action to support antibiotic conservation and the development of new drugs, diagnostics, and vaccines. The document, outlining several critical measures the government and industry must take to increase antibiotic effectiveness worldwide, was also drafted and signed by nine industry associations spanning 18 countries.

Global progress assessment of AMR initiatives in 2018:

This brings me back to where I started from, while analyzing what happened in this regard a year after the above declaration was signed. On January 23, 2018, at the World Economic Forum in Davos, Switzerland – the first independent analysis of pharmaceutical industry efforts to tackle drug resistance, was revealed by the AMF. It found companies are developing new drugs, as well as dismantling the incentives that encourage sales staff to oversell antibiotics, setting limits on the concentration of antibiotics in factory wastewater released into the environment, and tracking the spread of superbugs.

In the AMR Benchmark, GSK and Johnson & Johnson lead among the largest research-based pharmaceutical companies. A separate ranking of manufacturers of generic antibiotics features Mylan, Cipla, and Fresenius Kabi Global, in the leading positions. While Mylan leads the generic medicine manufacturers, Entasis, reportedly, leads the biotechnology group. 

Twenty-eight antibiotics are in late stages of development:

The other key findings of the 2018 study include mention of 28 antibiotics that are in later stages of development, targeting pathogens deemed critical AMR priorities by the WHO, and/or US Centers for Disease Control and Prevention. However, only two of these 28 candidates are supported by plans to ensure they can be both made accessible and used wisely if they reach the market. Be that as it may, the benchmark finds room for all companies to improve in this space, the report indicated.

Some major initiatives in India:

The good news is, ‘The National Policy for Containment of Antibacterial Resistance’, with similar objectives, was put in place in India by the Directorate General of Health Services, Ministry of Health & Family Welfare, way back in 2011. Further, on March 20, 2015, to strengthen the surveillance of antimicrobial resistance (AMR) in the country, Indian Council of Medical Research (ICMR) had set up a National Antimicrobial Resistance Research and Surveillance Network (AMRRSN) to enable compilation of national data of AMR at different levels of health care.

Again, in February 2017, the Indian Council of Medical Research (ICMR)  has put a new ‘Treatment Guidelines for Antimicrobial Use in Common Syndromes’, to achieve the same objectives. Despite this, as many medical experts opine, a large number of General Practitioners (GP), including hospitals, nursing homes continued over-prescribing antibiotics. Alarmingly, considered as the last line of defense antibiotics by many doctors – Colistin and Carbapenem resistant infections have also been reported from several Indian hospitals. All this adds further fuel to the AMR fire.

Another matter of huge worry in India:

The February 04, 2018 article titled, ‘Threats to global antimicrobial resistance control Centrally approved and unapproved antibiotic formulations sold in India,’ published in the British Journal of Clinical Pharmacology, highlight serious hurdles for controlling antimicrobial resistance in India, which has had parliamentary investigations into the failures of the country’s drug regulatory system. The study was conducted by researchers from Queen Mary University in London, Newcastle University and Lakshya Society for Public Health Education and Research in Pune. Some of the key findings of the study are as follows:

  • Extensive use unapproved of fixed dose combination (FDC) antibiotics is contributing to the rising rate of AMR in India, which is already one of the highest in the world.
  • Out of the 118 of FDC antibiotics being sold in India, only 43 (36 percent) were approved by the CDSCO. These 118 antibiotic formulations are being sold in 3307 brand names and manufactured by 476 entities. Of these, 464 were Indian manufactures, and 12 were MNCs.

The authors recommend work on understanding why unapproved formulations are being prescribed by medical professionals.

Conclusion:

As the above AARP Foundation article highlights, like all living beings, bacteria constantly evolve to survive. While encountering a new antibiotic, they quickly find ways to evade it, and continue to live or exist. Some have even developed cell wall like virtually impregnable shields, as it were, keeping antibiotics out. Others pump antibiotics out when they get in. Several deadly bacteria have even devised ways to deactivate antibiotics.

The comments made in the article titled, ‘The Future of Antibiotics and Resistance,’ published by The New England Journal of Medicine (NEJM) on January 24, 2013, is also worth noting. It says, the converging crises of increasing resistance and collapse of antibiotic research and development are the predictable results of policies and processes we have used to deal with infections for 75 years. If we want a long-term solution, the answer is not incremental tweaking of these policies and processes. Novel approaches, based on a reconceptualization of the nature of resistance, disease, and prevention, are needed.

The bottom line still remains, AMR is a humongous threat to the global population, not just in India. While its awareness is gradually increasing, much more painstaking work remains to be done by all, both individually and collectively, to contain this global health menace. It’s our responsibility to protect the well-being of our future generations.

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

Posted on by
Reply

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

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

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

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

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

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

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

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

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

Not a radically new concept:

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

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

Difference between ‘Precision’ and ‘Personalized’ Medicines:

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

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

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

Global initiatives taking off:

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

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

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

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

The market:

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

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

Faster US regulatory approval:

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

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

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

‘Precision Medicine’ in India:

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

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

Local research:

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

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

Local potential and market impact:

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

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

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

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

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

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

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

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

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

Some key strategic steps:

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

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

Conclusion:

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

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

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

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

India To Expand NLEM 2011: A Step In The Right Direction

Posted on by
Reply

Responding to growing discontentment on the flawed National List of Essential Medicines 2011 (NLEM 2011) and equally vociferous demand for its urgent rectification, on May 5, 2015, in a written reply to the Lower House of Indian Parliament (Lok Sabha) the Union Minister for Chemicals and Fertilizers – Mr. Ananth Kumar made the following submission:

“The Ministry of Health and Family Welfare, has constituted a Core Committee of Experts to review and recommend the revision of National List of Essential Medicines (NLEM) 2011 in the context of contemporary knowledge of use of therapeutic products.”

According to earlier media reports, the Government had formed this Core Committee in May 2014 under Dr. V.M Katoch, Secretary, Department of Health Research (DHR) and Director General, Indian Council of Medical Research (ICMR). However to utter dismay of many, even in a full year’s time, the Committee has not been able to come out with any tangible recommendations in this area.

In his reply from the floor of the Parliament, the Union Minister added with a tinge of reassurance:

“The Core committee has already held wide consultations with stakeholders and is likely to come out with its recommendations on the revised NLEM soon… The revised NLEM would form the basis of number of medicines which would come under price control,”

This reply from the Minister was in response to a query from a lawmaker on what steps have been taken by the Government to expand the list of NLEM 2011 and provide them to the poor at affordable prices.

Mr. Ananth Kumar also reiterated, the National Pharmaceutical Pricing Authority (NPPA) has already fixed the ceiling prices in respect of 521 medicines till date, out of 628 NLEM formulations included in the first schedule of DPCO, 2013.

“The revised NLEM would bring more drugs under price control”, the Minister said.

NPPA’s earlier initiative was thwarted:

It is worth noting that in 2014, to include all drugs of mass consumption, in addition to essential and life saving medicines, NPPA initiated an exercise to expand the NLEM 2011.

At that time, quite rightly I reckon, the pharmaceutical industry vehemently protested against this regulatory overreach of NPPA and sought judicial intervention at least in two High Courts of India.

Moreover, as is well known today, NPPA’s attempt to regulate prices of medicines of mass consumption got thwarted, when the Union Government intervened and directed the price regulator to withdraw its related internal guidelines. Coincidentally this lightning action was taken just before Prime Minister Narendra Modi’s schedule visit to the United States in end 2014.

Be that as it may, the industry observers consider the last week’s announcement of the Union Minister, from the floor of the Parliament, to expand the span of NLEM 2011 as a step in the right direction for improving access to affordable essential medicines for all in India.

A brief backdrop for ‘Essential Medicines’:

The World Health Organization (W.H.O) has defined ‘Essential Medicines’ as those that ‘satisfy the priority healthcare needs of the population’. It has been propagating this concept since 1977, when W.H.O published the first Model List of Essential Drugs with 208 medicines. All these medicines together provided safe, effective treatment for the majority of communicable and non-communicable diseases, at that time.

Every two year this list is updated. The current Model List of Essential Medicines, prepared by the W.H.O Expert Committee in April 2013, is its 18th Edition.

According to W.H.O, such ‘Essential Medicines’ are selected with due regard to disease prevalence, evidence on efficacy and safety, and comparative cost-effectiveness. The Organization categorically states:

“Essential medicines are intended to be available within the context of functioning health systems at all times in adequate amounts, in the appropriate dosage forms, with assured quality, and at a price the individual and the community can afford.”

Many countries of the world, India included now, have the National List of Essential Medicines (NLEM) and some have provincial or state lists as well, such as, in Tamilnadu Rajasthan and Delhi.

Health being a state subject in India, NLEM usually relates closely to Standard Treatment Guidelines (STGs) for use within the State Government health facilities. Ironically, such measures are currently being taken by just a small number of State Governments in the country.

NLEM – A forward-looking ongoing concept:

According to W.H.O, the concept of ‘Essential Medicines’ is forward-looking and ongoing. This idea prompts the need to regularly update the selection of medicines in the NLEM, reflecting:

  • New therapeutic options
  • Changing therapeutic needs
  • The need to ensure drug quality
  • The need for continued development of better medicines
  • Medicines for emerging diseases
  • Medicines to meet changing resistance patterns

As a part of its ongoing exercise, on May 8, 2015, The World Health Organization (W.H.O) by a ‘News Release’ announced addition of several new treatments for cancer and hepatitis C to its list of ‘Essential Medicines’, which the agency believes should be made available at affordable prices.

All 5 new products for the treatment of Hepatitis C, including sofosbuvir and daclatasvir, were included in the List. These medicines cure more than 90 percent of those infected and cost from US$63,000 to US$94,500 in the United States, depending upon the drug and treatment regimen.

Considering, new breakthroughs made in cancer treatment in the last years, W.H.O also revised the full cancer segment of the Essential Medicines List this year: 52 products were reviewed and 30 treatments confirmed, with 16 new medicines added in the list, including Herceptin of Roche, and Gleevec of Novartis.

“When new effective medicines emerge to safely treat serious and widespread diseases, it is vital to ensure that everyone who needs them can obtain them,” said W.H.O Director-General, Dr Margaret Chan. “Placing them on the WHO Essential Medicines List is a first step in that direction.”

India would also require putting similar effective systems in place for a robust, ongoing and time-bound review process for its NLEM.

Immense health and economic impact of ‘Essential Medicines’:

Globally the health and economic impact of ‘Essential Medicines’ have been proved to be remarkable, especially in the developing countries, as such drugs are one of the most cost-effective elements in healthcare system of any time. That’s why the stakeholders bestow so much of importance on a well thought out and properly crafted list of essential medicines by the astute experts appointed by the Government.

According to W.H.O, while spending on pharmaceuticals represents less than one-fifth of total public and private health spending in most developed countries, it represents 15 to 30 percent of health spending in transitional economies and 25 to 66 percent in developing countries.

In developing countries, such as India, pharmaceuticals are the largest Out of Pocket (OoP) household health expenditure. “And the expense of serious family illness, including drugs, is a major cause of household impoverishment.”

Flawed NLEM could multiply access to medicines problems:

Despite well-documented global evidence regarding high potential of health and economic impact of ‘Essential Drugs’, if the NLEM does not include right kind of drugs and remains flawed, it could have significant adverse impact on the overall access to ‘Essential Medicines’ in India.

In addition, properly structured NLEM could help setting the right course in the procurement and supply of medicines in the public sector – national or state Government schemes that reimburse medicine costs, and also for domestic production of drugs in the country.

A quick overview of NLEM in India:

There was no functional NLEM in India before 2002. According to a paper titled “Decisions on WHO’s essential medicines need more scrutiny”, published in the BMJ on July 31, 2014, in India the first National Essential Medical List (NEML) was prepared in 1996. However, this list was neither implemented for procuring drugs nor were STGs drawn up.

It all started in 2002, when the National Drug Policy of India, announced in that year, was subsequently challenged through a Public Interest Litigation (PIL) in the Karnataka High Court on the ground of being inflationary in nature. The Honorable Court by its order dated November 12, 2002 issued a stay on the implementation of that Policy.

This judgment was challenged by the Government in the Supreme Court, which vacated the stay vide its order dated March 10, 2003 and ordered as follows:

“We suspend the operation of the order to the extent it directs that the Policy dated February 15, 2002 shall not be implemented. However we direct that the petitioner shall consider and formulate appropriate criteria for ensuring essential and lifesaving drugs not to fall out of the price control and further directed to review drugs, which are essential and lifesaving in nature till 2nd May, 2003”.

As a result DPCO 1995 continued to remain operational, pending formulation of a new drug policy, based on NLEM based span of price control, as directed by the Honorable Supreme Court of India. Necessitated by this directive of the Apex Court of the country, the first NLEM of India came into effect in 2002.

In 2011, NLEM 2002 was subsequently reviewed and re-evaluated by a committee of 87 experts from various fields, and was replaced by the NLEM 2011 with 348 drugs.

In the recent years, following a series of protracted judicial and executive activities, the National Pharmaceutical Pricing Policy 2012 (NPPP 2012) came into effect on December 7, 2012. In the new policy the span of price control was changed to all drugs falling under the National List of Essential Medicines 2011 (NLEM 2011) and the price control methodology was modified from the cost-based to market based one. Accordingly the new Drug Price Control Order (DPCO 2013) was notified on May 15, 2013.

However, the matter is still subjudice, as NPPP 2012 would ultimately require passing the acid test of scrutiny by the Supreme Court of India, in the future days.

A recent study emphasizes need for urgent expansion of NLEM:

A March 2015 independent evaluation of DPCO 2013, which controls prices of essential medicines in India as featured in the NLEM 2011, brought to light some interesting facts. The Public Health Foundation of India (PHFI) and the Institute for Studies in Industrial Development released this report titled “Pharmaceutical Policies in India: Balancing Industrial and Public Health Interests” at a conference on pharmaceutical policies in India, held in New Delhi from 3 to 7 March, 2015.

This independent evaluation would most probably be submitted to the Supreme Court where PHFI is one of the petitioners in a case challenging the current NPPP 2012.

The study found that price regulations of NLEM 2011 are limited to just 17 percent of the total pharmaceutical market in India. This leaves 83 percent of the domestic pharma market free from price control, providing only marginal financial relief to patients for all essential medicines, in its true sense, as desired by the Supreme Court of India. Thus, one of the key recommendations of this study is to review the NLEM 2011, urgently.

“Clearly the interests of the pharmaceutical industry have received precedence over the interest of the patient population,” the report highlighted.

Anurag Bhargava, of the Himalayan Institute of Medical Sciences, was quoted in March 2014 BMJ Article titled, “Analysts in India call for urgent expansion of essential medicines list”, saying:

“This is a matter of concern given that the NLEM was not drafted as an instrument for price regulation. It is a representative rather than a comprehensive list of medicines utilized in actual practice. To serve as a reference for rational prescribing, the NLEM includes only a few model dosage forms, strengths, and combinations of drugs.”

NLEM 2011 fails to reflect public health priorities:

The report, with relevant details, brings to the fore that NLEM 2011 has failed to reflect India’s public health priorities. It underscores the following glaring deficiencies in NLEM 2011, which covers just:

  • 1 percent of drugs for anemia
  • 5 percent of respiratory drugs
  • 7 percent of antidepressants
  • 15 percent of drugs for diabetes
  • 18 percent of drugs for tuberculosis
  • 13 percent of anti-malarial drugs
  • 23 percent of cardiac drugs
  • 35 percent of antibiotics

Areas for revision in NLEM 2011:

A critical appraisal of NLEM 2011 was done in the above-mentioned 2014 BMJ paper and also by the NPPA separately.

Taking all these into consideration, some key areas of concerns related to NLEM 2011 floats at the top of mind. A few examples of important issues, which need immediate attention, are as follows (not necessarily in the same order):

  • Other key strengths and dosage forms of the same drugs covered under NLEM 2011
  • Analogues of scheduled formulations not covered
  • Close substitutes in the same therapeutic class not covered
  • Some essential drugs listed in the W.H.O model list and even in Delhi list are missing in the NLEM 2011
  • Several essential HIV and Cancer drugs are not included in NLEM 2011
  • Essential oral anti-diabetic medicines, like glimeperide and glicazide do not find place in NLEM 2011, especially when the list in the DSPRUD for Delhi includes anti-diabetic medicines such as glimepiride, sitagliptin, vildagliptin, saxagliptin
  • Commonly used anti-asthmatic medicines like almeterol and montelukast are missing in NLEM 2011
  • When W.H.O model List (EML) includes capreomycin, cycloserine, ethionamide, kanamycin and para-aminosalicylic acid for treatment of multi-drug resistant tuberculosis, these drugs are missing in NLEM 2011 list
  • Though a large number of Fixed Dose Combinations (FDCs) are prescribed to treat common ailments in India, especially in certain therapeutic groups such as respiratory, cardiovascular, anti-diabetic, dermatology, anti-malarial and anti TB/MDR TB, most of these are missing in NLEM 2011
  • While the W.H.O list mentions 21 vaccines, the NLEM 2011 mentions only nine vaccines
  • A separate list of lifesaving drugs based on existing lifesaving drugs list of government agencies like the CGHS needs to be worked out
  • Pediatric formulations need to be included in NLEM
  • Inclusion of some medical devices which are already covered under the definition of drugs under the Drugs and Cosmetics Act 1940
  • Essential and well-selected lifesaving patented drugs should also feature in the NLEM, just as what W.H.O has done this month by adding to its ‘Essential Medicines List’ all the five patented new curative treatments for hepatitis C, besides 16 new cancer drugs.

Thus, in its present form the NLEM 2011 needs a critical relook and revision, mainly in the light of the missing drugs and keeping in view of the requirements under various National Health Programs as well as the National Formulary of India 2010.

The BMJ paper also highlights, the Indian Academy of Pediatrics has come out with a list of ‘Essential Drugs’ for children in India. Such a list might be consulted for the Pediatric List of Essential Medicine within the NLEM. Provision should be made to review the NLEM at two yearly intervals, as is currently practiced by the W.H.O.

Civil Society steps in:

Accordingly, in August 2014, seven Civil Society Organizations in a letter to Minister Ananth Kumar with a copy to Prime Minister Narendra Modi, among others, wrote as follows:

“Limiting all price regulation only to a list of 348 medicines and specified dosages and strengths in the DPCO 2013 goes against the policy objective of making medicines affordable to the public. The National List of Essential Medicines, a list of 348 rational and cost-effective medicines, is not the basis for production, promotion and prescription in India. In reality the most frequently prescribed and consumed medicines are not listed in the NLEM.”

Healthcare: China on a fast track, India crawls through a slow lane: 

Interestingly, to help improve economic growth and boost domestic consumption, China has recently decided to floor the gas pedal on the fast lane of healthcare reform, while India chose to continue to crawl through its slow lane.

Interestingly, both the countries want to draw similar sets of trend lines for health and economic progress of their respective nations.

This has been vindicated by Reuters report of May 9, 2015, when it highlighted, China would increase its healthcare subsidies by 19 percent this year as part of efforts to deepen social reforms and strengthen safety nets.

The report also indicated, economists view this measure as crucial for China to improve the quality of its healthcare, if it wishes to remake its economy and boost domestic consumption. They say a stronger safety net will encourage Chinese to spend more and save less.

As opposed to the Chinese scenario, in India, the Union Budget 2015-16 came as a real dampener for the healthcare space in the country. This assumes greater significance, as the budget was planned by the reform oriented Modi Government.

Despite the dismal state of current public healthcare services, the annual budgetary allocation for healthcare has been kept at Rs. 33,152 Crore, just a tad more than Rs. 30,645 Crore of 2014-15, with no visible indication for any healthcare reform measure in the country, any time soon.

Conclusion:

‘Essential Medicines’ based drug price control, as was directed by the Honorable Supreme Court of India, is just not far sighted, but a potential game changer in the healthcare space of the country.

While looking at the bigger picture, this policy also promises a significant contribution in the overall economic progress of the nation.

To make this policy effective in the longer term, NLEM should be fair, impartial, far sighted, up to date, robust and beyond obvious any controversy, which includes its authors… just as the spirit behind the good old saying: “Caesar’s wife must be above suspicion.”

Unfortunately, NLEM 2011 is mired with many shortcomings for all the wrong reasons, as discussed above.

The incumbent Government would require striking a just and right balance between public health interest and expectations of the Pharma industry in this critical area. Taking the right policy decision in a transparent an effective manner, balancing the healthcare and economic interest of the country, would be critical.

That said, Pharma industry in India, I reckon, would also not be devastatingly impacted with the possible expansion of NLEM. This is mainly because, currently only 17 percent of the total pharmaceutical market in India comes under price control, based on the span of NLEM 2011 formulations. In any case, the balance 83 percent of the domestic pharma market still falls under the free-pricing zone.

Even when DPCO 1995 came into force, which continued till DPCO 2013 became effective, 20 percent of the total domestic pharmaceutical market was under price control.

Moreover, there was no provision for automatic annual price increases for price-controlled drugs under DPCO 1995. Whereas DPCO 2013 has a provision for annual price increases for all such essential drugs based on WPI. As a result, MRPs of all price controlled essential drugs have gone up effective April 1 of this year and would continue to happen so every year, as long as NPPP 2012 remains in force.

Under this complex mosaic and fast evolving backdrop, the announcement of the Union Minister for Chemicals and Fertilizers – Mr. Ananth Kumar on the floor of the Parliament last week is a laudable one.

To help improve access to affordable essential medicines for all in the country, the Minister has reiterated, “The expanded NLEM would bring more essential drugs under price control.”  This categorical affirmation by the Government in power, though belated, is a step in the right direction…for both better healthcare and also its consequential critical impact on the economic progress of India.

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.

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’?

Deadly ‘Superbugs’: The larger issues

Posted on by
Reply

Every year, April 7 is observed as ‘World Health Day’ across the globe. This year, 2011, is no exception. However, interestingly considering the increasing debate on the antibiotic resistance ‘Superbug’, the theme of this year has been very aptly coined as “No action today, no cure tomorrow”.

April 2011 issue of ‘The Lancet’ reported again the presence of drug-resistant bacteria NDM-1 in the public water system of Delhi.

Some observers in this area commented that this report is clearly aimed at raising alarm by recycling an old claim that has been found to be contentious, clearly suggesting indirectly that foreigners who visit India for medical and cosmetic treatments may carry back the deadly microbes with them to their respective countries.

The new report attempts to establish that the ‘Superbug NDM-1′ is no longer a hospital-born infection but can also spread through contaminated water and food. Understandably, this has raised a hue and cry in India.

Ministry of Health ridicules ‘The Lancet’ April study:

Last week the Ministry of Health rejected the above study observing that it was not only conducted with “motivated intentions”, but is illegal too. As transport of  water samples for such study out of the country requires prior permission from regulatory authorities. The authenticity of the samples also appears to be questionable, as these were reportedly to have been collected by a TV reporter.

However, just a day after the government rejected ‘The Lancet’ report, it formed a committee to look into the findings of the study, as announced by Dr R K Srivastava, Director General of Health Services, Government of India.

However, ‘The Lancet’ stands by this study report.

August 2010 report of ‘The Lancet’:

One will perhaps recall that on August 11, 2010, “The Lancet” published similar article highlighting that a new antibiotics-resistant “Superbug” originating from Pakistan has taken its first life. This happened when a patient brought to a hospital in Belgium died in June 2010 after having met with a car accident in Pakistan, where from the person got infected with this “Superbug”.

The above article was written by a team of international researchers including an Indian. The study elaborated that a new variety of enzyme named after India’s national capital New Delhi, called, “New Delhi Metallo beta lactamase” in short “NDM 1” turns any bacteria into a deadly “Superbug”, making it resistant to all types of antibiotics, leaving virtually no cure in sight. This deadly “Superbug” was reported to have already reached the United Kingdom through patients who acquired it from the hospitals in India and has the potential to precipitate serious health issues across the world. “The New Delhi Superbug” was discovered even earlier: The ‘The Lancet’ report generated a sharp reaction in India and from some of its authors regarding its authenticity. Some experts even termed this study as the ‘Western plot to undermine medical tourism in India’. A leading daily of India reported, “Indian medical journal first documented Superbug”. It stated that that the first ever formal documentation of this ‘Superbug’ was made in 2009 at the P.D. Hinduja National Hospital and Medical Research Centre located in Mumbai. This finding was published in the ‘Journal of the Association of Physicians in India (JAPI’) in March 2010. The reason for the emergence of the ‘Superbug’ was attributed to the ‘worrisome outcome of the indiscriminate use of antibiotics’. “Unfair to blame the country for the ‘New Delhi’ Superbug”: Reacting to the August article, Indian health authorities opined at that time, “It is unfortunate that this new bug, which is an environmental thing, has been attached to a particular country.” The reasons being, “Several superbugs are surviving in nature and they have been reported from countries like Greece, Israel, the U.S., Britain, Brazil and there is no public health threat and no need to unnecessarily sensationalize it”.

Some experts, however, feel, “such drug resistant pathogens, is a global phenomenon and is preventable by sound infection prevention strategies which are followed in any good hospital.”

Based on this report the ‘National Center for Disease Control of India’ started working on guidelines for appropriately recording these types of nosocomial (hospital acquired) infections.

“Superbug Hype” and Medical Tourism:

Many people of both India and Pakistan felt since then that in absence of an effective response by the health authorities, especially in India, the fast evolving Medical Tourism initiatives providing medical services ranging from complicated cardiovascular, orthopedic and cerebrovascular surgery to other life-threatening illnesses, may get adversely impacted.

The ‘blame game’: Experts have opined that overuse, imprudent or irrational use of antibiotics without any surveillance protocol is the root cause for emergence of “Superbugs”, though some Indian parliamentarians had termed the August article as the propaganda by some vested interests.

It has been alleged that the study was funded by the Wellcome Trust and Wyeth, the two global pharmaceutical companies who produce antibiotics to treat such conditions, together with the European Union.

In this context it is worth mentioning that ‘The Lancet’ article of August 2010 in its disclosures says:

“Kartikeyan K Kumarasamy has received a travel grant from Wyeth… David M Livermore has received conference support from numerous pharmaceutical companies, and also holds shares in AstraZeneca, Merck, Pfizer, Dechra, and GlaxoSmithKline, and, as Enduring Attorney, manages further holdings in GlaxoSmithKline and Eco Animal Health. All other authors declare that they have no conflicts of interest.” Not a first time reported incidence: This type of situation has indeed some precedents. When ‘MRSA’ was reported for the first time, it caused similar scare. However, this time many experts feel that it is too early to conclude whether or not ‘NDM-1’ will eventually prove to be more dangerous than ‘MRSA’. Several such “Superbugs”, as stated earlier, have already been reported from countries like Greece, Israel, USA, UK, and Brazil. As I know, in the battle against infectious diseases involving both the scientists and the bacteria, the later had  to succumb mostly, in the long run. ‘NDM-1′ perhaps will be no exception. All concerned must continue to make it happen, not by mere wishful thinking but by establishing a strong procedural mechanism to keep a careful vigil on the reasons for emergence of drug resistant bacterial strains in the country.

The World Health Organization (WHO) perspective:

On Saturday, August 21, 2010 the WHO commented, “while multi-drug resistant bacteria are not new and will continue to appear, this development requires monitoring and further study to understand the extent and modes of transmission, and to define the most effective measures for control”.

International Cooperation:

US based Center for Disease Control and Prevention (CDC), which is known as one of the world’s best-known institute for handling ‘Superbugs’, will help India in its capacity building efforts to better detect pathogens like NDM-1.

In India, the National Center for Disease Control (NCDC) with state of art facilities is expected to commence working from the next year. The facility is expected to be equipped with highly-advanced bio-safety level-II and BSL-III laboratories and would cost around Rs 382.41 Crore.

The larger issue:

The larger issue is that antibiotic resistance is fast becoming a global health concern as drug-resistant bacteria can turn a simple infection life threatening. According to the World Health Organization, ‘some 440,000 new cases of tuberculosis resistant to different types of drugs were detected last year in 60 countries across the world.’

Thus the emergence of drug-resistant ‘Superbug’ is being seen by many experts as a natural process of evolution of organisms. However, it goes without saying that indiscriminate use of antibiotics is hastening this deadly process.

R&D focus shifted more towards chronic illnesses:

Besides the reasons attributed to emergence of such “Superbugs”, as discussed earlier, one more important issue I could foresee in today’s environment compared to the past decades.

This issue possibly lies in the drastic shift in focus of pharmaceutical R&D from discovery of novel drugs for short term treatment of infectious diseases to discovery of potentially greater money spinner drugs for life-long treatment of non-infectious chronic illnesses like, metabolic disorders (diabetes), hypertension, cardiovascular diseases, psychiatric disorders, cancer, vaccines etc. This shift in the R&D focus has obviously been prompted by the tilt in the prevalence of the disease pattern towards the same direction. As a consequence, one notices hardly any significant and novel molecules in the research pipelines of either global or local pharmaceutical companies to treat  antibiotic-resistant infections.

As reported by the ‘Infectious Diseases Society of America’ between 1983 and 1987 sixteen new patented antibiotics were approved by the US FDA, while from 2003 to March 2011 only seven patented antibiotics were launched in the international market.

It is understandably not an ‘either/or’ situation so far as R&D target molecules are concerned. However, as we all know, in life-threatening conditions both types of drugs have their respective places to save precious lives.

Conclusion:

Let the global innovators ponder over the issue for newer antibiotics to counter the emerging ‘Superbugs’.

In India, the Ministry of Health should consider strictly implementing the measures suggested by the task force set up last year to prevent indiscriminate use of antibiotics. Such measures include a ban on sale of antibiotics without prescriptions and simultaneously regular audits of prescriptions of the doctors to stop irrational use of such drugs.

The need of the hour is a well-orchestrated effort by the Government, members of the civil society and the medical fraternity to have full control on this growing menace, through tangible, prudent and truly patient-friendly action .
