A Disruptive Innovation to Fight and Cure Intractable Diseases

Several important facets of health care often arrest general attention. These are also widely discussed, analyzed and argued vehemently – with each person or group trying to justify one’s own point of view. Among these, following 6 critical areas, broadly dominate the deliberations:

  • Incredible advancement in the medical science driving health care,
  • Infrastructure, facilitators and providers of health care,
  • ‘Wolves of health care in sheep’s clothing’, as described by many
  • Large populations facing inadequate availability and access to health care,
  • The need for Universal Health Care (UHC)
  • Public investments, policies and regulations governing health care.

In this article, I shall focus only on the first area – incredible recent advancement in the medical science driving health care, especially the very recent developments on a disruptive innovation called ‘Gene Therapy’.

Gene Therapy:

As some would know, one of the latest developments in the pharma world, relates to marketing approval in the United States and Europe of ‘Gene Therapy’ – a disruptive innovation in the medical science.

This technique of treatment using genes to manage, cure or prevent many intractable diseases are fast gaining ground globally, including India – at a slower pace, though. As I said, in America, the first gene therapy has already obtained the approval of the US-FDA in August 2017, closely followed by the second in October 2017, with the third waiting in the wings. In the European Union (EU), the first gene therapy was approved in 2012, but faced some commercial issues that I shall discuss later in this article.

During approval of the first gene therapy in the United States (US), the FDA Commissioner Scott Gottlieb reportedly said, this new frontier in medical innovation has the ability to reprogram a patient’s own cells to attack a deadly disease, such as cancer, creating an inflection point to treat, and even cure many intractable illnesses.

According to an October 10, 2017 publication of the U.S. National Library of Medicine, gene therapy may allow doctors to treat a disorder by inserting a gene into a patient’s cells instead of using drugs or surgery. Extensive research is ongoing, adopting several approaches to this treatment, including:

  • Replacing a mutated gene that causes disease with a healthy copy of the gene.
  • Inactivating, or “knocking out,” a mutated gene that is functioning improperly.
  • Introducing a new gene into the body to help fight a disease.

Thus, gene therapy is fast emerging as a promising treatment for a number of life-threatening diseases, including inherited disorders, some types of cancer, and certain tough to treat viral infections. That said, the technique being risky, is still under study to make it safer the patients. Currently, it is being tested only for diseases that have no other cures.

The first approval of gene therapy in the United States:

On August 30, 2017, US-FDA took a historic decision with its approval for the first ever gene therapy in America – meeting an unmet need in its true sense, and thus creating a major milestone in medical science. US-FDA approved this treatment for certain pediatric and young adult patients with a form of Acute Lymphoblastic Leukemia (ALL) – resistant to standard treatment, or which often relapses. The overall remission rate within three months of this treatment was found 83 percent in clinical trials.

This path-breaking therapy (tisagenlecleucel) is named Kymriah, and is made by Novartis. Nevertheless, it is worth noting that the treatment was developed by a group headed by Carl H. June  at the University of Pennsylvania and licensed to Novartis.

A customized treatment:

The US-FDA approval letter to Novartis says, “Kymriah is a genetically modified autologous T-cell immunotherapy. Each dose of Kymriah is a customized treatment created using an individual patient’s own T-cells, a type of white blood cell known as a lymphocyte. The patient’s T-cells are collected and sent to a manufacturing center where they are genetically modified to include a new gene that contains a specific protein (a chimeric antigen receptor or CAR) that directs the T-cells to target and kill leukemia cells that have a specific antigen (CD19) on the surface. Once the cells are modified, they are infused back into the patient to kill the cancer cells.”

Nevertheless, Kymriah can cause life-threatening side effects, such as dangerous drops in blood pressure. This has prompted US-FDA to caution that hospitals and doctors should be specially trained and certified to administer this therapy, and require stocking of drugs to control severe reactions, if and when required.

The price tag is jaw dropping:

As  reported by New York Times (NYT), Kymriah will be given to patients just once and must be made individually for each, costing US$ 475,000. Novartis reportedly has said, if a patient does not respond within the first month after treatment, there will be no charge. The company also said it would provide financial help to families who were uninsured or underinsured. This is indeed a commendable gesture.

The second USFDA approval for gene therapy:

Just about a week ago, on October 18, 2017, US-FDA approved Yescarta (axicabtagene ciloleucel) of Kite Pharma Inc. – a Gilead company. This is gene therapy is to treat adult patients with certain types of large B-cell lymphoma who have not responded to or who have relapsed after at least two other kinds of treatment.

Initially, 54 percent of patients on Yescarta reportedly had complete remissions with their tumors disappearing. Another 28 percent had partial remissions, where tumors shrank or appeared less active on scans. After six months, 80 percent of the 101 were still alive.

Just as Kymriah, Yescarta will also reportedly be introduced gradually, and be available only at centers where doctors and nurses have been trained in using it. This is, again, due to its serious side effects, which include high fevers, crashing blood pressure, lung congestion and neurological problems.

As reported, Kite Pharma hopes that Yescarta will eventually be approved for earlier stages of lymphoma, rather than being limited to patients with advanced disease who have been debilitated by multiple types of chemotherapy that did not work.

Yescarta will cost less than Kymriah at US$ 373,000 per patient. This is a single dose treatment to be infused into a vein, and must be manufactured individually for each patient. About 3,500 people a year only in the United States is estimated to be candidates for this therapy.

Yet another gene therapy is likely to get US-FDA approval soon:

Close on the heels of these two developments, yet another gene therapy is likely to get US-FDA approval in the coming months. On October 12, 2017, Spark Therapeutics – a gene therapy company in the United States, reportedly won unanimous support from a US-FDA advisory panel for its gene therapy – Luxturna (voretigene neparvovec), after the experts concluded that the benefits of this gene therapy outweighed its risks.

Luxturna – a one-shot treatment, has shown to reverse blindness by restoring vision in children with an inherited form of blindness, and shows potential to restore blood-clotting function to hemophiliacs, or even cure rare diseases outright. However, as the analysts estimate, the cost of Luxturna will be hefty, which could even be more than Kymriah of Novartis – at US$ 1 million per patient.

The first gene therapy in Europe was not commercially viable:

As stated above, in 2012, the first gene therapy – Amsterdam-based Uniqure’s Glybera (alipogene tiparvovec), was approved by the European Medicines Agency (EMA) for the EU market. The product was indicated for treatment of rare inherited disorder – lipoprotein lipase deficiency (LPLD).

However, with treatment cost of €1m+ per patient, Glybera was reportedly the most expensive therapy ever approved in Europe. Interestingly, in April 2017, Uniqure decided to terminate post-marketing studies required for prolongation of its existing EU conditional market approval, for its extremely limited usage, making the product commercially non-viable.

These four developments give me a sense of both – the fast pace of progress of gene therapy and also its possible commercial vulnerability, due to astronomically high prices coupled with a limited number of current usages linked to the specific disease types.

Gene therapy research in India:

According to the paper titled, “Gene therapy in India: a focus,” published by the Journal of Biosciences in June 2014 – ‘starting from 1998, the Indian government is playing a leading role in the advancement of gene therapy research in India by providing enormous financial support to scientists and clinicians through its various funding agencies like Department of Biotechnology (DBT), Department of Science and Technology (DST), Indian Council of Medical Research (ICMR), etc.’

India is not far behind other Asian countries in the field of gene therapy. In Asia, China is the leader with 16 research laboratories, followed by Japan (13), India (10), South Korea (4), Israel (3) and Taiwan (3), the paper says.

The laboratories established in India to conduct gene therapy research are: Advanced Centre for Treatment, Research and Education for Cancer, Mumbai (1998), University of Delhi (2002), Saha Institute of Nuclear Physics, Kolkata (2004), Indian Institute of Science, Bengaluru (2005), Actis Biologics Private Limited (2005), Mumbai, Center for Stem Cell Research, Vellore (2010), Vellore Institute of Technology, Vellore (2012), Institute of Life Sciences, Bhubaneswar (2012), Narayana Nethralaya, Bengaluru (2013).

Conclusion:

As deliberated above, gene therapy reflects an incredible advancement in the medical science driving health care. This is primarily because, the disruptive innovation is aimed at treating genetic diseases at the molecular level by correcting the defective genes.

The fact, as captured in the worldwide gene therapy data table, that between 1989 and February 2016, over 2,300 gene therapy clinical trials have been conducted – 93 of which being in phase III while 3 in phase IV, further vindicates the rapid pace of evolution of this science.

As stated before, the critical process of this treatment reportedly involves ‘introduction of new genes into cells, to restore or add gene expression, for the purpose of treating disease. Most commonly a mutated gene is replaced with DNA encoding a functional copy. Alternatively, DNA encoding a therapeutic protein drug may be introduced.’ However, the exorbitant current cost of this novel treatment, for various reasons, severely limits its access to a vast majority of the global population, at least for now.

Be that as it may, the disruptive medical innovation culminating into gene therapy of date, is expected to open new vistas of opportunity to fight and cure several life-threatening intractable diseases. This game changing advancement in the medical science, no doubt, would help provide a new lease of life only to some, mostly due to its price barrier. Nevertheless, for many, it does carry a new hope for access to this life changing therapy – probably at some point of time in future. God willing!

An Evolving Paradigm of ‘Price-Value Model’ Of Pharma Value Delivery System

Posted on by
Reply

May 4, 2016 edition of the ‘MIT Technology Review’ published an interesting article carrying the headline, “The World’s Most Expensive Medicine Is a Bust”.

The obvious question that floats at the top of mind: What is this most expensive drug in the pharma history, and why has it failed commercially, despite being a product of disruptive innovation and a marvel that stands out in the space of contemporary drug innovation? 

The product is called Glybera (alipogene tiparvovec). It heralded the dawn of the “first gene therapy” in the Western world, whose approval helped ignite an explosion of investment and excitement around treatments that correct DNA, as the MIT article said.  

Glybera promises to cure rare inherited diseases with one-time repairs to a person’s DNA. A single dose of gene therapy can change the genetic instructions inside a person’s cells in ways that last many years, or even a lifetime. 

Interestingly, even with this unprecedented product offering, the product has become a commercial flop, due to its staggering million-dollar price tag, which very few patients can afford.

Is this an extreme example of price-value relationship for a new breakthrough pharma product? Yes, of course!  Nevertheless, it makes us ponder on some key fundamentals, afresh, such as:

  • The core purpose of drug innovation
  • The price-value relationship of even breakthrough drugs

The proper understanding of these points comprehensively, especially the above two fundamentals, would enable the drug companies to achieve both, the core purpose of intricate drug innovation initiatives, and also making these medicines commercially successful with increased access to patients, through innovative ‘value delivery’ mechanisms.

I believe, the pharmaceutical industry is now at the threshold of a paradigm shift. The new paradigm would signal a metamorphosis in the price-value equations for all drugs, mostly due to changing socio-political environment, across the world, as we have started witnessing in the topmost free economy of the world – the United States.

Pharma business is a ‘value delivery system’: 

Way back in June 2000, an article published in ‘McKinsey Quarterly’ on delivering value to the customers, deliberated on a 1988 paper of Michael J. Lanning and Edward G. Michaels. The study combines the value-maps developed in the price-value models with the idea of the “business system,” which was introduced in 1980.

The paper titled, “A business is a value delivery system,” emphasizes the importance of a clear, well-articulated “value proposition” for each targeted market segment. This means a simple statement of the benefits that the company intends to provide to each segment, along with the approximate price the company will charge each segment for those benefits. 

Looking at this concept in pharma perspective:

Keeping the above paper in perspective, when we look at the pharma value delivery system, besides the key benefits that a drug offers, one of the most critical value parameter continues to be the financial value.

The healthcare value chain, across the world, has started sharpening its focus on the drug cost today, more than ever before. This is primarily based on the differential value that a drug offers as compared to its closest alternatives. We may like it or not, it is happening irrespective of, whether the drug in question is a breakthrough innovation, or an off-patent high-priced generic medicine.

As I said before, not just in India, the affordability of health care in general, and medicines in particular, is rapidly emerging as a key concern for all developed and the developing nations, including the United States.

Thus, even after careful consideration of all novel product’s benefits and the costs associated with these, the stakeholders’ focus is getting sharper on the overall financial value of the product offerings to the patients. This is reality, and can’t just be wished away by any measure of powerful and expensive advocacy campaigns, together with clever media management. 

The drug companies may continue to crib about it, but this will possibly lead them nowhere, in the long term. Instead, they would require to search for a workable win-win and level headed solution, for this most fundamental business issue.

Understanding the evolving paradigm:

We are fast arriving at this new paradigm. There, the financial value of a drug, in the ‘value delivery system’ of pharma marketing, would occupy the center stage. The drug companies would need to arrive at this financial value, not just by understanding the professional mindset of the doctors and taking them on board somehow, but by properly understanding what would the majority of stakeholders want to pay for a new drug, and then perhaps work backwards to translate that finding into reality. 

Its successful application would soon assume a pivotal role in the pharma value delivery system. A company may contemplate pricing a drug high, limiting its access to a few rich, and still succeed in making its cash register ringing, such as, some new hepatitis C or cancer drugs. Nonetheless, this could ultimately make their overall business socio-politically too vulnerable, and may not be sustainable either, in the long run. 

The same old and current approach does not create a wholesome value for a new drug to most of the customers, despite the company having a state of art ‘value delivery platform’, for unleashing a dazzling marketing blitzkrieg.                                 

The pharma marketing strategy remains unchanged and stale: 

At a time, when a paradigm shift is taking place, especially in the way the entire world views at the price-value equation of a new drug, the overall strategic approach of the pharma marketers, as I see it, still remains in the old paradigm, with its roots firmly entrenched there.

I think it so, because the traditional pharma marketing has always been a unilateral communication process, predominantly involving the doctors, and trying to fathom their needs, wants and professional mindset.

Accordingly, the product value delivery process for the doctors, with or without the medical representatives, is basically woven around those needs, wants and mindsets of the target doctors. It, by and large, continues even today, with some cosmetic changes in tools and formats here or there. 

Therefore, when the basic marketing and communication process aims at effectively delivering the value of drugs, let us discuss briefly what does the core value of a drug mean?

The value of a drug: 

For this purpose, I reckon, it would be prudent to avoid an ethereal approach to arrive at the financial value of a drug, such as, what is the cost of a life, as often raised by many pharma players. A practical approach to resolve this issue would benefit all, in every way.

Without going much into the core purpose of pharma innovation, usually the drug companies define the value of a medicine based on what they think about its attributes. Accordingly, respective players arrive at its financial value, that the patients or the payers must pay for, if they want to have an access to it. 

Usually not many independent studies are conducted by the drug companies to ascertain how much the majority of stakeholders, including the governments, payers and patients, would want to willingly pay for a new drug, after well considering its value offerings.

Competitive Scenario:

The ever increasing, and virtually obsessed focus on drug ‘innovation’, while justifying the high financial value of a medicine for the patients, also restricts competition, especially for newer ones. For most of the patients this situation is a double whammy.

Additionally, the consolidation process within the industry is also fuelling this situation further. The virtual monopoly of a few companies with some new drugs, in key therapy segments, such as, diabetes, cancer, vaccines and HIV, is restricting the overall competitive environment. This would continue.

A September 24, 2014 Article, published in the ‘Insight’ of Bain & Company on the throws some light on the subject. It says, “over the past 20 years, and especially since 2000, building leadership in a category has become a crucial route to success in pharma. Seven of our 10 leading value creators, including Roche in oncology and Novo Nordisk in diabetes care, generated at least 50 percent of their revenues from one therapeutic area or primary care. In two cases – Biogen Idec in neurology and Celgene in oncology – more than 90 percent of revenues came from a single therapeutic area.”

As I said, this process is expected to continue, it is necessary for the drug companies, governments, other payers and the patients understand the new paradigm, and act accordingly to address this issue to protect mutual benefit.

If it does not happen, the evolving socio-political environment, across the world, would occupy the driver’s seat to navigate through this complexity, in the healthcare space in general and pharma in particular, safeguarding the patients’ health interest. 

The core issue:

In the prevailing scenario, the core issue that gets reinforced, yet again, as raised by many, including the World Health Organization (WHO), is the growing inherent conflict between predominantly the profit driven business goals of the pharma players, and the public health interest of a nation.

Possibly for this reason, Dr. Margaret Chan, the Director General of the World Health Organization (WHO), at a briefing to discuss the Ebola outbreak in West Africa at the UN Foundation in Washington on September 3, 2014 said:

“Big Pharma’s greed for profits, not lack of funding, delaying Ebola treatment development.” 

Many countries are now seriously striving to arrive at a middle path to resolve this perennial conflict, India included. The drug companies may wish to take note of it.

I discussed this issue in an article published in this Website titled, “Is The Core Purpose of Pharma Business Beyond Profit Making?” on November 10, 2014.

Conclusion:

As the above ‘McKinsey Quarterly’ paper articulated, the strength of the buying proposition for any customer is a function of the product value minus the price. In other words, the ‘surplus value’ that the customer will enjoy once that product is paid for. As the paper clarified, the “value” in a price-value map will necessarily be informed guesses, though after well-considering multiple variables.

Delivering more of this ‘surplus value’ to patients, willy-nilly, would soon be the name of the game, especially for the winners in both the global and local pharma industry. 

In the entire drug sector, including India, this ‘price-value model’ could help a pharma company ascertain the sustainability of its competitive position, well considering the stakeholders’ perspective, and accordingly take the right business decision.

Thus, proper understanding of the ‘surplus value model’ while pricing a drug, and its immaculate execution through state of the art marketing and communication strategies, will separate the men from the boys, for sustained excellence in the pharma business.

Sans understanding of this ‘price-value model’, which is so important in the evolving new paradigm of a pharma value delivery system, a pharma player would risk getting caught in a tough headwind, especially with new high-priced products. This situation could, in turn, jeopardize its long term success, and even erode the well-earned company reputation, in tandem, at times mercilessly.

Cancer Cure: Inching Towards The ‘Holy Grail’?

Posted on by
Reply

In a Press Conference on August 20, 2015, the 39th President of the United States, now 90-year-old  Jimmy Carter, revealed (video) that during a liver surgery earlier this month the doctors diagnosed that he has cancer. The type of cancer that he is suffering from is called melanoma, which has already spread to his liver and brain. Medical jargon would term it as deadly metastatic cancer.

Though the surgeons have removed the liver tumor, and well-targeted radiation treatment for four other small tumors in his brain has already been initiated, the original site of the melanoma, the lethal skin cancer, has reportedly not been found, as yet.

Mr. Carter’s medical treatment has started with an infusion of a new class of drug that uses the human immune system to fight cancer cells. The drug has been reported to work not only in advanced metastatic cancer, but also in the old age of patients. The former American President appears optimistic about the treatment outcomes with this new therapy, ‘placing his fate in the hands of God’, though initially he thought that he had just weeks to live.

I shall deliberate in this article, in an easy to understand language, though briefly, the promises offered by two latest options for cancer cure. One of these two, has just become available to patients and the other one, after an initial jaw-dropping success, is undergoing further tests in a renowned research laboratory of the United States.

Two novel pathways for cancer treatment:

Until recently, surgery, radiation and chemotherapy used to be the three common options for cancer treatment. One breakthrough option has just been launched and more in the offing.

In search of a cure for cancer, pathbreaking outcomes of medical research, especially in the following two areas, are significant:

A. Immunotherapy: It is a revolutionary approach to cancer treatment. The first of this novel class of drugs has just come to the market, with which Mr.Jimmy Carter is now reportedly being treated.

B. Re-programming cancer cells back to normal: Success has just been achieved in laboratory studies with this technique. It holds a strong promise to cure cancer, universally.

A. Immunotherapy:

On June 1, 2015, in an article titled, ‘Cure for terminal cancer’ found in game-changing drugs, “The Telegraph” – well-regarded international news daily, reported on anti-cancer immunotherapy drugs, as follows:

“Terminally ill cancer patients have been ‘effectively cured’ by a game-changing new class of drugs. In one trial, more than half of patients who had just months to live saw deadly tumors shrink or completely disappear.”

“In recent days, the results of trials of a number of treatments which harness the body’s immune system have been announced at the American Society of Clinical Oncology’s annual conference in Chicago. They show promise in the fight against skin cancer and lung disease.”

As we know, most of the cancers are deadly. All these grow and spread, as they manage to hide from the immune system, disguising the life-threatening danger. Thus, medical research scientists pondered that the human immune system could play a critical role in the fight against cancer and even cure, by harnessing its ability to fight the deadly disease, effectively and decisively.

To achieve this goal, this class of new cancer drugs work by allowing the body to recognize and attack cancer as any other harmful invader to the body. It effectively blocks a cellular pathway that hinders the ability of the human immune system to attack cancer cells.

At present, to treat different types of cancer, more number of immunotherapy drugs are undergoing clinical investigations.

Brilliant treatment outcomes, but not universal:

It has been reported, about one third of patients taking immunotherapy for the treatment of cancer experienced positive results. Those who responded to this therapy, showed immediate effect with their tumors shrinking or vanishing in a matter of weeks. As a result, the patients who had no more than weeks or months to live, just as former US President Jimmy Carter, have gone into remission for years and continuing with their normal lives.

It has also been reported, otherwise such patients could expect to live just nine months, if given standard treatment of cancer. Researchers said, they were hopeful that half of the patients responded to immunotherapy would end up “living disease-free”.

These drugs are expensive, costing roughly US$150,000 per year, which is a part of a different debate altogether.

Not a ‘magic bullet’:

Besides its high cost and outstanding quality of results, it is worth noting that immunotherapy is not a ‘magic bullet’ for all types of patients and in all cancer. It, therefore, throws a challenge for the oncologists to understand, why immunotherapy benefits only to some cancer patients, and who are those patients?

Moreover, there is a possibility of immunotherapy sending immune system of some patients to overdrive, precipitating auto-immune disorder that may attack also the healthy cells.

Thus, immunotherapy is not the ‘Holy Grail’ for the treatment of cancer, neither it is nowhere near a perfect drug for the treatment of all types of cancers in all patients.

Two key findings:

In this regard, two key findings of the researchers on immunotherapy are as follows:

  • Roughly around 15 to 20 percent of patients could experience shrinkage or remission of cancer
  • Half of the patients who responded found it lasting for at least six months

Thus, immunotherapy can at best be a cure for only some terminally ill cancer patients, mostly for some time, but not for all.

“In the hands of God”:

All these factors on immunotherapy probably would help us to understand, why an erudite person like Mr. Jimmy Carter said, though optimistic about the new treatment, he is placing his fate ‘in the hands of God’.

B. Re-programming cancer cells back to normal: 

The question, therefore, comes up now, if immunotherapy is not the ‘Holy Grail’ for cancer treatment that the research scientists have been intensively searching for, is there anything else coming up for cancer cure?

It appears so. A totally different approach to re-program the cancer cells back to normal has very recently been reported by Mayo Clinic’s Florida Campus in the United States. With this, cancer researchers’ dream of making the tumor cells morphing back to normal cells, they once were, would probably come true.

The research findings, published in Nature Cell Biology on August 24, 2015, represents ‘an unexpected new biology that provides the code, the software for turning off cancer,’ said the senior investigator of this study.

In the normal process, cells in the human body divide constantly to replace themselves and stop dividing when they have replicated sufficiently. However, unlike the normal cells, cancer cells do not stop dividing, they go out of control, leading to huge cell reproduction and tumor growth.

For the ultimate cure of cancer, scientists at Mayo Clinic have now reportedly succeeded in reversing the process responsible for the normal cells from replicating too quickly.

Possible cure now within sight?

This could ultimately lead to a newer class of breakthrough treatment that would be able to reverse cancerous growth in the human body, possibly curing cancer, without the need of surgery, chemotherapy, radiation or even immunotherapy.

Scientists at the Mayo Clinic have said that their initial experiments in some aggressive types of cancer are quite encouraging. They have successfully done this in very aggressive human cell lines from breast and bladder cancer.

Towards the ‘Holy Grail’:

In pursuit of finding a cancer cure, research scientists have been making commendable progress, over a period of time.

In the last few years, spectacular breakthroughs in treatment of cancer have been possible from the increasing genetic and biological understanding of the researchers, especially in ascertaining exact defects in the DNA code of human genes that cause cancer.

Ability to sequencing human genome has offered a key tool to the researchers to compare the DNA codes of cancerous and normal cells and identify the differences.

From within the 20,000 human genes, around 500 cancer genes have been reportedly discovered and are being catalogued. Clear understanding of what happens precisely when the cells divide uncontrollably and cancer spreads in different parts of the patients’ body, is taking place with commendable progress of various research initiatives in this area.

Based on the current knowledge on human genome, a number of new drugs have been and are being developed to target the cancer-causing genes with great accuracy. Such types of drugs are called ‘personalized medicines’, as these act on specific gene abnormality of patients related to certain types of cancer. Sophisticated laboratory tests facilitate treatment with ‘personalized medicines’. These are more effective with lesser side-effects, as compared to generally used anti-cancer drugs, prescribed to all cancer patients.

However, the question keeps lingering, ‘Is the Holy Grail for cancer cure has now come within sight?’

Conclusion:

Medical scientists continue to take rapid strides towards better and more effective treatment for cancer, if not cure, with fewer side-effects.

Claims for long remissions with immunotherapy, are being reported for some patients with even metastatic cancer and also in old age, just like former President of America – Mr. Jimmy Carter.

The success achieved by the scientists of ‘Mayo Clinic’ in re-programming rogue cancer cells back to normal, is stunning.

Being successful in this effort, the researchers have compared cancer with a complex software program of life. When it goes out of control, ‘instead of the code for normal cells, a code for making abnormal cells is executed’. This new study signals a strong possibility of bringing the cancer cells back to normal.

Medical experts keep their fingers crossed. Although, some of them do apprehend that there may never be a single ‘Magic Bullet’ to cure all types of cancer in all patients. This is mainly because cancer involves a large number of different disease areas, such as, breast, lung, bowel, prostate, blood and so on.

But hope refuses to fade out, as science continues to keep unravelling spectacular breakthroughs in this direction, at a fairly brisk pace. All these researches may be cancer types or patient types specifics, but the progress is taking place in the right direction.

Even in the ‘Mayo Clinic study’, scientists have been, so far, successful in re-programming the breast and bladder cancer cells back to normal, though they believe that this success sends a strong signal of an “early and somewhat universal event in cancer.”

Immunotherapy is undoubtedly a path breaking step that ensures cure in some types of cancer and in some categories of patients. However, if re-programming the cancer cells back to normal, eventually becomes an ‘universal event’ in the treatment of this generally frightening disease, no doubt, the medical science is now slowly but surely inching towards the ‘Holy Grail’ for cancer cure…at long last.

Pharma & Healthcare: Where The Healers Turn Looters?

Posted on by
Reply

Two news reports of the last week, though no longer shocking, made me think exactly the same way as the headline of this article epitomizes.

These reports are not just two isolated instances, but an integral part of a similar chain of events that I partly addressed in one of my earlier blog posts titled, “Is The Core Purpose of Pharma Business Much Beyond Profit Making?” of November 10, 2014.

With the fist clenching media reports of just the last week, I shall try to dwell upon that in absence of good governance how two of the greatest healers and the medical care givers in the arena of healthcare – the doctors and the hospitals, are being increasingly perceived by the common citizens as nothing less than looters.

The doctors:

A November 21, 2014 report highlights that the Medical Council of India (MCI) has summoned over three hundred doctors from various parts of India, based on an anonymous complaint, for taking lakhs of rupees as bribes from an Ahmedabad based pharmaceutical company. All those 300 doctors have been told to bring copies of their Income Tax returns and bank statements.

Just a year ago, in September 2013, the Chief Vigilance Commissioner reportedly received a letter alleging that doctors were taking bribes from Pharma companies. The complaint was forwarded to the Health ministry. The MCI took over the case in December 2013 and formed a subcommittee to investigate the doctors.

The complaint details that the Ahmedabad-based pharma company has been paying to the doctors not just huge cash, but also gifting them cars and flats, besides sponsoring foreign trips for the family.

In return, the involved doctors are allegedly prescribing that Ahmedabad based pharma company’s products that are priced 15 to 30 percent higher than those of well-established other pharma players.

In addition, according to reports, the doctors would also air on the Television sets placed at their respective clinics, advertisements of the pharma company products against hefty cash or equivalent in kind.

Although, the allegations of unholy nexus between pharma players and the doctors are continuity of a good old saga, the risk taking incentives that it provides to the wrong doers are very significant. The anonymous letter alleged that the concerned pharma company’s profit zoomed from zero to Rs. 400 Crore in a period of just 5 years.

According to available reports, the MCI has already questioned 166 doctors, out of which 7 are senior doctors from Maharashtra, including 3 physicians from Mumbai.

The hospital:

Another report on the subject that appeared yesterday is related to overcharging for an oncology medicine of Novartis – Sandostatin LAR, over the last nine months by the well-known Tata Memorial Hospital of Mumbai.

According to the report, even when Novartis revised the price of Sandostatin LAR from Rs. 65,499 for a 20mg vial to Rs 32,000 during Oct-Dec 2013 and the chemists in the hospital’s vicinity were selling the same vial for Rs 32,000, Tata Memorial continued to sell it at Rs 48,296.

The report also states that patients could have saved much more, if the hospital had prescribed an Octreotide generic of the same strength, Octride Depot 20mg by Sun Pharma with an MRP of Rs 17,800 is sold at Tata Memorial for Rs 12,157, instead of Sandostatin LAR 20mg.

However, the newspaper claims, “DNA was the first to report about the price disparity at the hospital on Nov 5. Tata Memorial Hospital has decided to reimburse cancer patients who were overcharged for a Novartis-branded oncology medicine over the last nine months.”

Interestingly, we get to know only about a few of such instances, only when these are reported either anonymously or by some employees or through rare impartial investigative journalism of international standard.

Treatment of dreaded diseases like Cancer also not spared:

The above hospital case assumes immense importance, as it is related to a dreaded disease and an expensive cancer drug. In real every day life, many such cases of various hues and colors are taking place in India incognito, at the cost of patients.

A scary scenario:

According to the ‘Fact-Sheet 2014′ of the World Health Organization (WHO), cancer cases would rise from 14 million in 2012 to 22 million within the next two decades. It is, therefore, no wonder that cancers figured among the leading causes of over 8.2 million deaths in 2012, worldwide.

A reflection of this scary scenario can also be visualized while analyzing the growth trend of various therapy segments of the global pharmaceutical market.

A recent report of ‘Evaluate Pharma (EP)’ has estimated that the worldwide sales of prescription drugs would reach US$ 1,017 Bn. by 2020 with a Compounded Annual Growth Rate (CAGR) of 5.1 percent between 2013 and 2020.

Interestingly, oncology is set to record the highest sales growth among the major therapy categories with a CAGR of 11.2 percent during this period, accounting for US$ 153.4 Bn. of the global pharmaceutical sales.

High incidence of cancer in India:

A major report published in ‘The Lancet Oncology’ states that in India, around 1 million new cancer cases are diagnosed each year, which is estimated to reach 1.7 million in 2035.

The report also highlights, though deaths from cancer are currently 600,000 -700,000 annually, it is expected to increase to around 1.2 million during this period.

The Lancet Oncology study showed, while incidence of cancer in the Indian population is only about a quarter of that in the United States or Europe, mortality rates among those diagnosed with the disease are much higher.

Experts do indicate that one of the main barriers of cancer care is its high treatment cost that is out of reach for millions of Indians.

Breast cancer is the most common type of cancer, accounting for over 1 in 5 of all deaths from cancer in women, while 40 percent of cancer cases in the country are attributable to tobacco.

Cancer drug price – a global issue to address:

As the targeted therapies have significantly increased their share of global oncology sales, from 11 percent a decade ago to 46 percent last year, increasingly, both the Governments and the payers, almost all over the world, have started feeling quite uncomfortable with the rapidly ascending drug price trend.

In the top cancer markets of the world, such as, the United States and Europe, both the respective governments and also the private insurers have now started playing hardball with the cancer drugs manufacturers.

There are several instances in the developed markets, where the stakeholders, such as, National Institute for Health and Care Excellence (NICE) of the United Kingdom and American Society of Clinical Oncology (ASCO) are expressing their concerns about manufacturers’ charging astronomical prices, even for small improvements in the survival time.

Following examples would give an idea of global sensitivity in this area:

After rejecting Roche’s breast cancer drug Kadcyla as too expensive, NICE reportedly articulated in its statement: “A breast cancer treatment that can cost more than US$151,000 per patient is not effective enough to justify the price the NHS is being asked to pay.”

In October 2012, three doctors at Memorial Sloan-Kettering Cancer Center announced in the New York Times that their hospital wouldn’t be using Zaltrap. These oncologists did not consider the drug worth its price. They questioned, why prescribe the far more expensive Zaltrap? Almost immediately thereafter, coming under intense stakeholder pressure Sanofi reportedly announced 50 percent off on Zaltrap price.

Similarly, ASCO in the United States has reportedly launched an initiative to rate cancer drugs not just on their efficacy and side effects, but prices as well.

Developments in India:

India has already demonstrated its initial concern on this critical issue by granting Compulsory License (CL) to the local player Natco to formulate the generic version of Bayer’s kidney cancer drug Nexavar and make it available to the patients at a fraction of the originator’s price. As rumors are doing the rounds, probably some more patented cancer drugs would come under Government scrutiny to achieve the same end goal.

I indicated in my earlier blog post that the National Pharmaceutical Pricing Authority (NPPA) of India by its notification dated July 10, 2014 has decided to bring, among others, some anticancer drugs too, not featuring in the National List of Essential Medicines 2011 (NLEM 2011), under price control. These prices have already in force.

Not too long ago, the Indian government reportedly contemplated to allow production of cheaper generic versions of breast cancer drug Herceptin in India. Roche – the originator of the drug ultimately surrendered its patent rights in 2013, apprehending that it would lose a legal contest in Indian courts, according to media reports.

Biocon and Mylan thereafter came out with biosimilar version of Herceptin in the country with around 40 percent lesser price.Herceptin,

Hence, affordable pricing of cancer drugs would continue to remain a key pressure point, as it just happened yet again.

The government to intervene again:

According to a media report of the last week, the new government in India is planning to control prices of anti-cancer drugs to address this critical issue.

As the current National List of Essential Medicines (NLEM) does not include many important anti-cancer medication, Tata Memorial Centre of Mumbai has recommended to the government that oncology drugs, such as Trastuzumab, Erlotinib, Irinotecan, Lenalidomide, Capecitabine, All Trans Retinoic Acid (ATRA), Bendamustine, Rituximab, Temozolomide (TMZ), Zoledronic acid, Megestrol acetate and Letrozole, should be added to the NLEM.

As a first step towards this direction the National Pharmaceutical Pricing Authority (NPPA) has invited comments on the same from the pharmaceutical industry and other stakeholders to bring these drugs under price control.

Quoting NPPA the report states, “the recommendations are based on factors such as the ability of the drug to improve the overall survival chances of the patient. The other factors include higher priority to drugs that have the potential to cure a fraction of patients versus those that have been proven to only prolong lives; the number of patients potentially impacted in India based on data from population based cancer registries of the National Cancer Registry Program; the non-availability of alternative medications of the same or other pharmacological class that can act as a reasonable ‘substitute’; and price of the drug to patients and the differential in price between various brands.”

Although this is a welcome move to most of the patients, the pharma industry would certainly not be happy with this development, because of very obvious reasons and is expected to strongly oppose this initiative of the government. Let us wait and watch how this scenario unfolds further.

Conclusion:

In pursuit of the Eldorado to generate more and more wealth, shorn of least concerns for majority of patients, quite a few companies are not sparing even the dreaded diseases, such as cancer, pushing many patients to abject poverty, if not untimely death.

Increasingly, many healthcare players across the world are reportedly being forced to pay heavily for ‘unethical behavior and business practices’ by the respective governments. Unfortunately, no such steps are being taken in India, not just yet.

At least on paper, for errant doctors and hospitals there is MCI to take prompt remedial measures. For implementation of Drug Price Control Order (DPCO) there is NPPA, though effectiveness of these two seemingly powerful bodies are far from the expectations of the stakeholders, occasional reported jingoism notwithstanding.

Currently in India, there are no legally binding ‘codes of pharma marketing practices’ in place. Even the Department of Pharmaceutical does not seem to have any legal jurisdiction for taking penal action against the errant pharma players for marketing malpractices or misdemeanor.

In this chaotic scenario, is it not quite challenging to fathom how would the government possibly discourage any healthcare or pharma player from turning looter instead of playing the expected role of a healer, ensuring beyond doubt that there is no wolf in sheep’s clothing?

“Meeting Unmet Needs of Patients”: A New Direction

Posted on by

The much-hyped phrase of the global pharma majors – ‘meeting unmet needs of patients’, is very often used to create an aura around newer patented drugs of all kinds, from original to banal, including evergreen varieties such as:

Evergreen Drug/Brand Medical Condition Original Drug/Brand
Levocetirizine (Vozet) Allergies Cetirizine (Zyrtec)
Escitalopram (Lexapro) Depression Citalopram (Celexa)
Esomeprazole (Nexium) Acid reflux Omeprazole (Prilosec)
Desloratadine (Clarinex) Allergies Loratadine (Claritan)
Pregabalin (Lyrica) Seizures Gabapentin (Neurotonin)

I do not have any terrible issue with this usage, as many stakeholders, including various governments, have already started differentiating between the ‘Chalk’ and the ‘Cheese’ kinds of patented products and contemplating future course of action, accordingly. The recent development in South Africa is one such example.

That said, there is now a greater need to ponder over the much bigger picture in the same context and direction, which would improve predictability of treatment outcomes by manifold. Simultaneously, such R&D initiatives would help reducing the overall cost, especially for dreaded diseases like cancer, mainly through highly targeted drugs and consequently avoiding the risk and associated wastage, as often happens with the prevailing ‘trial and error’ therapy approach, thereby benefitting the patients immensely. This is mainly because no drug is 100 percent effective with inconsequential side-effects for all patients of any disease type.

Genetics and Genomics Science made it possible:

With already acquired knowledge in genetics, genomics and genome sequencing capability, it is now possible to precisely predict a person’s susceptibility to various disease types and proactively working out measures to help either avoiding ailments, such as, non-infectious life threatening and chronic diseases altogether, if not, making their treatment more predictable and less expensive, as stated above.

If organized efforts are made to extend the application and benefits of this science to a larger section of population, those R&D initiatives can really be construed, unquestionably, as ‘meeting unmet needs of the patients’, just as ‘first in kind’ category of innovative drugs are recognized by the scientific community and the civil society as a whole.

A treatment revolution in the offing:

Expectations are rapidly building up that evolving genetics and genomics science based technological know-how would ultimately revolutionize the practice of medicine ushering-in the pathway of personalized medicine for a large number of patients.

Definition: 

A report from the Tufts Center for the Study of Drug Development defines personalized medicine as “Tailoring of medical treatment and delivery of health care to individual characteristics of each patient, including their genetic, molecular, imaging and other personal determinants. Using this approach has the potential to speed accurate diagnosis, decrease side effects, and increase the likelihood that a medicine will work for an individual patient.”

The aim: 

The aim of personalized medicine is, therefore, to make a perfect fit between the drug and the patient. It is worth noting that genotyping is currently not a part of clinically accepted routine. However, it is expected to acquire this status in the western world, shortly.

To give a very quick example, genetic differences within individuals determine how their bodies react to drugs such as Warfarin – a blood thinner taken to prevent clotting. It is of utmost importance to get the dosing right, as more of the drug will cause bleeding and less of it will not have any therapeutic effect.

In the field of cancer, genetic tests are now being done by some oncologists to determine which patients will be benefited most; say with Herceptin, in the treatment of breast cancer.

Thus, with personalized medicine the health of a patient will be managed based on personal characteristics of the individual, including height, weight, diet, age, sex etc. instead of defined “standards of care”, based on averaging response across a patient group. Pharmacogenomics tests like, sequencing of human genome will determine a patient’s likely response to drugs.

Disease prevention: 

In addition, such medicines would help identifying individuals prone to serious ailments such as, metabolic, cardiac, endocrine, auto-immune, psychosomatic, including cancer of various types; enabling physicians to take appropriate preventive measures much before disease manifestations and in that process would help containing the overall treatment cost.

Cost of genome sequencing:

Sir John Bell, Professor of Medicine at Oxford University, reportedly said in early December 2012 that personalized medicine for all could soon be a clear possibility, as everybody will be able to have their entire DNA make-up mapped for as little as £100 (Rs.10, 000 approx.).

This estimate seems to be realistic, as the price of genome sequencing has fallen by 100,000-fold in 10 years. This cost is expected to further decline, as genome of any person essentially remains unchanged over time. Thus, this information might become a part of an individual’s medical record allowing the doctors to use it as necessary.

Summary of key advantages: 

To summarize, the expected benefits from personalized medicine, besides very early diagnosis as stated above, are the following:

1. More Accurate Dosing: Instead of dose being decided based on age and body weight of the patients, the physicians may decide and adjust the dose of the medicines based on the genetic profiling of the patients.

2. More Targeted Drugs: It will be possible for the pharmaceutical companies to develop and market drugs for patients with specific genetic profiles. In that process, a drug needs to be tested only on those who are likely to derive benefits from it. This in turn will be able to effectively tailor clinical trials, expediting the process of market launch of these drugs.

3. Improved Healthcare: personalized medicine would enable the physicians to prescribe ‘the right dose of the right medicine the first time for everyone’ without any trial or error approach, resulting in much better overall healthcare.

Current use:

Though these are still the early days, initial usage of personalized medicine is now being reported in many areas, such as:

Genetic analysis of patients dealing with blood clots: Since 2007, the U.S. Food and Drug Administration has been recommending genotyping for all patients being assessed for therapy involving Warfarin.

Colorectal cancer: For colon cancer patients, the biomarker that predicts how a tumor will respond to certain drugs is a protein encoded by the KRAS gene, which can now be determined through a simple test.

Breast cancer: Women with breast tumors can now be effectively screened to determine which receptors their tumor cells contain.

In addition, this approach would also help clinicians to determine which particular therapy is most likely to succeed on which patient.

Present outlook: 

A September 2013 article published in Forbes Magazine titled, “Personalized Medicine May Be Good For Patients But Bad For Drug Companies’ Bottom Line” says, although personalized medicine offers tremendous potential for patients, because of the dual burdens of expensive clinical trials and diminished revenue potential, the concept may become unsustainable in the long term, the attitude of regulators will be critical to drug companies’ willingness to embrace personalized medicine, and to its wider application.

In my view, for greater interest of patients to ‘meet their unmet needs’ global pharma, majors, academics, respective governments and the drug regulators should find a way out in this new direction, sooner.

Indian initiatives:

Some companies, both well known and lesser known, are making collaborative progress, keeping low profile, in the genome sequencing area in India, which will ultimately make expensive treatments, such as cancer, more predictable and simultaneously affordable to many.

The concerns:

While the progress in the field of personalized medicine is quite heartening, some experts have reportedly been sounding a note of caution. They strongly feel that DNA code sequencing brings to light a “very real privacy concerns” of individuals.

The key argument being, if genome sequencing is extended to entire population, individuals and their relatives could then be identified and tracked by matching their DNA with the genome stored in the respective health records. This move, as contemplated by the opponents, could “wipe out privacy” with a significant impact on the society.

A paper published in ‘Scientific American’ dated January 2014, titled “What Fetal Genome Screening Could Mean for Babies and Parents” deliberated that today doctors are closer than ever before to routinely glimpsing the full genetic blueprints of a fetus just months after sperm meets egg. That genomic reconstruction would reveal future disease risk and genetic traits even as early as the first trimester of pregnancy – raising another ethical issue that could hugely impact parents’ decision threshold for deciding to terminate a pregnancy or influencing how they rear their child.

Thus, all these ethical and social issues in the development and usage of personalized medicine must be appropriately addressed under a well deliberated ethical, social, legal and regulatory framework of each country.

Conclusion:

Though in Europe and to some extent in the United States, treatments based on personalized medicine have already been initiated, we are still in a nascent stage for this novel concept to get translated into reality for the benefit of a much wider population across the world.

Lot of grounds may still need to be covered, especially in the realm of medical research and also to work out the regulatory pathways for personalized medicine in healthcare by the pioneers of this great concept and more importantly by effectively addressing the ethical concerns raised on this subject.

If collaborative initiatives are taken jointly by academia, R&D based global pharma majors and medical diagnostic players towards this new direction with a clearer focus and  supported by the law makers, a huge unmet needs of patients will truly be met, giving yet again a fresh impetus to the much hyped phrase “Meeting Unmet Needs of Patients”, though in a refreshingly new direction.
