‘The Memory Thief’ Still Eludes Grasp Of Pharma R&D

Over several decades, in fact, since its very inception, pharma R&D has been playing a crucial role in alleviating diseases of various types – from severe acute infections, to a large variety of non-infectious chronic illnesses, including many dreaded diseases, such as, cancer.

In the battle against diseases, pharma research and development initiatives, both by a large number of academia and also the pharma players, have mostly won, decisively. R&D has been consistently coming out with flying colors, both in finding cures and also in effective disease management, to prolong and improve the quality of life of billions of people, the world over.

However, there is still an important disease area, where pharma R&D has not been successful yet. Without any prior warning, this disease stealthily affects the human brain and completely erases the entire lifetime memory of the person, gradually but surely, over a relatively short period of time. This disease is known as Alzheimer’s, following the name of Dr.  Dr. Alois Alzheimer, who first detected it in 1906. Due to its devastating impact on human memory, some, very appropriately, term the Alzheimer’s disease – ‘The memory thief’.

I discussed this subject in one of my previous articles titled, “It Took 90 Years To Accept The Dreaded Disease Discovered In A Mental Asylum”, published in this Blog on December 01, 2014.

A recent alarm for a future epidemic:

A January 6, 2016 paper titled, “Sounding the alarm on a future epidemic: Alzheimer’s disease”, published by the well reputed public research university in the United States, ‘The University of California, Los Angeles (UCLA), made the following noteworthy observation:

“If the aging trend illustrates the success of public health strategies, it also raises the specter of a major public health crisis – a sharp rise in the number of people living with Alzheimer’s disease.”

Causing havoc in many lives and families:

‘Alzheimer’s Disease Education and Referral (ADEAR) Center’ of the United States, currently ranked Alzheimer’s disease as the sixth leading cause of death in the United States, but recent estimates indicate that the disorder may rank third, just behind heart disease and cancer, as a cause of death for older people.

According to Mayo Clinic, the frightful disease – Alzheimer’s, is progressive in nature. At the onset, the afflicted persons may exhibit just mild confusion and some difficulty in remembering.

Tragically, in around five years or a little after, Alzheimer’s would erase the entire lifetime memory of most of the affected persons, when they may even forget the important people in their lives and undergo dramatic personality changes.

The dreaded disease – Alzheimer’s, still without any effective medication in place, has been causing havocs in many lives and families since long, involving many great international personalities too. It is one of those ailments, where the disease process mostly commences almost a decade before the visible appearance of above clinical symptoms.

Worldwide Projections of Alzheimer’s Disease Prevalence:  

The above UCLA report highlights the worldwide projections of Alzheimer’s disease prevalence from 2005 to 2050, which includes both the early and late stage patients.

According to this report, the number of people afflicted by this total memory-erasing disease, would grow from 35.26 million in 2015 to as high as 106.23 million populations in 2050, as follows:

Year Alzheimer’s disease prevalence (in Millions)
2005 25.73
2010 30.12
2015 35.26
2020 41.27
2025 56.55
2040 77.49
2050 106.23
Similar situation in India: 

The situation in India seems to be no different, though we are living today in the midst of the hype of ‘Demographic Dividend’.

According to the March 2012 report of ‘The Population Reference Bureau’ of Washington DC of the United States, India’s population with ages 60 and older, who are more prone to Alzheimer’s disease, is projected to increase dramatically over the next four decades, from 8 percent in 2010 to 19 percent in 2050. By mid-century, this age group is expected to encompass 323 million people, a number greater than the total US population in 2012.

Currently available treatment:

At present, there are no treatments available that can stop or slow down the progression of Alzheimer’s disease in the brain of the affected persons.

As I wrote earlier, very often the onset of this disease starts decades before the visible manifestation of even preliminary symptoms. Thus, there is a critical need for early medical interventions to arrest the disease progression.

Again, quoting Mayo Clinic, current Alzheimer’s disease medications and management strategies may at best temporarily improve symptoms. These symptomatic treatments can sometimes, help Alzheimer’s patients maximize cognitive and other related functions to the extent possible, and thereby maintain independence for a little while longer.

Primary reasons:

Many earlier research had postulated that plaques and tangles are primarily responsible for the permanent damage and destruction of nerve cells.

While the plaques are abnormal clusters of beta-amyloid protein fragments between nerve cells, tangles are twisted fibers made primarily of a protein called “tau” that accumulates in the brain cells, damaging and killing them.

The appearance of these two in the brain structure makes the affected persons suffer from almost irreversible memory loss, altered thinking pattern and associated behavioral changes, which are usually serious in nature.

However, I shall discuss below about a very recent research that is focusing on a different and novel target.

Key hurdles in Alzheimer’s drug development:

Despite all these, almost at a regular interval, we have been getting to know about various new studies on Alzheimer’s disease, mostly from academic and scientific institutions. It clearly vindicates, at least, the global academia and also some pharma players, are working hard to get an effective key to unlock the pathway of Alzheimer’s disease process.

The hurdles in developing a suitable drug for effective treatment of Alzheimer’s disease are many. A paper titled, “Researching Alzheimer’s Medicines: Setbacks and Stepping Stones Summer 2015”, published by the Pharmaceutical Research and Manufacturers of America (PhRMA) – a trade association of leading biopharmaceutical researchers and biotechnology companies of the United States, cited the following three major reasons as examples:

  • Scientists still do not understand the underlying causes and mechanisms of the disease. It remains unknown whether many of the defining molecular characteristics of the disease are causes, effects, or signs of progression. This scientific knowledge gap makes the identification and selection of viable targets for new medicines difficult. 
  • Current preclinical models of Alzheimer’s disease are limited in the extent to which they can be extrapolated or translated to the human condition. Better models are needed to facilitate preclinical testing of drug candidates and better predict the effects of the drug in humans. 
  • The absence of validated, non-invasive biomarkers to identify disease presence and progression means the diagnosis is delayed until an individual becomes symptomatic. This makes it particularly challenging to evaluate, enroll, retain, and follow up with patients in clinical studies. It also makes it challenging to assess the effects of the drug candidate. Ultimately, this leads to long and very expensive clinical trials. 

The PhRMA publication also states that “researchers believe that no single medicine will be able to defeat Alzheimer’s; rather, several medicines will probably be needed to combat the disease. Thus, researchers need not one, but an array of options to prevent or treat Alzheimer’s disease.”

High rate of R&D failure, with flickers of success:

The above PhRMA publication also indicates, between 1998 and 2014, 123 medicines in clinical development have been halted and have not received regulatory approval.

In this rather gloomy R&D scenario, there are also some flickers of success in this pursuit.

In a recent study, the scientists at the University of Southampton announced that their findings added weight to evidence that inflammation in the brain is what drives the disease. A drug, used to block the production of these microglia cells in the brains of mice, had a positive effect. The study, therefore, concluded that blocking the production of new immune cells in the brain could reduce memory problems seen in Alzheimer’s disease. This finding is expected to pave the way for a new line of treatment for Alzheimer’s disease.

Currently, most drugs used for the treatment of dementia targeted amyloid plaques in the brain, which are considered as a key characteristic of people with the Alzheimer’s disease. According to an article published in Forbes on March 20, 2015, several amyloid-clearing drugs have failed to show statistically significant benefits in large clinical trials. Notable among those are Bapineuzumab – developed by Elan Pharmaceuticals, Pfizer and Johnson & Johnson failed in 2009; Solanezumab of Eli Lilly failed in 2012; and so did Gantenerumab of Roche in 2014.

The latest study, as quoted above, published in the journal ‘Brain’, on January 8, 2016 suggests that targeting inflammation in the brain, caused by a build-up of immune cells called microglia, could halt progression of the disease.

Another flicker of hope is, another drug being developed by Biogen Idec for the treatment of Alzheimer’s disease appeared to slow down the inexorable cognitive decline of patients’, though in a small and a preliminary study.

Lack of research funding is a critical impediment:

Be that as it may, many experts believe that not enough is still being done in Alzheimer’s research, especially in the area of funding.

In an article titled, “Alzheimer’s disease: are we close to finding a cure?” published by ‘Medical News Today (MNT)’ on August 20, 2014, quoted the Alzheimer’s Society, as follows:

“Dementia is the biggest health and social care challenge of our generation, but research into the condition has been hugely underfunded. This lack of funding has hampered progress and also restricted the number of scientists and clinicians working in the dementia field.”

As an illustration, MNT mentioned that in the United States Alzheimer’s research received US$504 million in funding from the National Institutes of Health (NIH) in 2014, while cancer received more than US$5 billion. Breast cancer alone received more funding than Alzheimer’s at US$674 million. 

Quoting an expert in this field the report highlighted, “Other diseases have demonstrated that sustained investment in research can improve lives, reduce death rates and ultimately produce effective treatments and preventions. We have the tools and the talent to achieve breakthroughs in Alzheimer’s disease, but we need the resources to make this a reality.”

Conclusion:

From the published research reports, it appears that the quest to decipher the complicated Alzheimer’s disease process continues, at least by the academic and scientific institutions, with equal zest. 

These scientists remain committed to finding out the ‘magic bullet’, which would be able to effectively address the crippling disease. As a result, the research has also moved from discovery of effective amyloid-clearing drugs to search for new molecules that targets inflammation in the brain, caused by a build-up of immune cells called microglia. 

Undeniably, the challenges ahead are still too many.

Nevertheless, enough confidence is also building up to halt the epidemic of Alzheimer’s by overcoming those hurdles, the world over. Experts are hoping that both a cure and also successful preventive measures for the disease, are not too far anymore.

Though some Global Pharma majors invested significantly to discover effective drugs for Alzheimer’s disease, overall research funding in this area is still far from adequate, according to the Alzheimer’s Society. 

For various reasons, not many pharma players today seem to believe that it would be financially prudent for them to make significant investments in developing new molecules for the treatment of Alzheimer’s – the disease that robs memory of millions of people, completely, and without any prior warning whatsoever.

‘The Memory Thief’ continues to prowl, undeterred, still eluding otherwise brilliant Pharma R&D, across the world.

Patented Drug Pricing: Relevance To R&D Investments

The costs of most of the new life saving drugs, used in the treatment of dreaded diseases such as cancer, have now started going north at a brisk pace, more than ever before.

From the global pharma industry perspective, the standard answer to this disturbing phenomenon has remained unchanged over a period of time. It continues to argue; with the same old emphasis and much challenged details that the high drug price is due to rapidly escalating R&D expenses.

However, experts have reasons to believe that irrespective of R&D costs, the companies stretch the new drug prices to the farthest edge to maximize profits. Generation of highest possible revenue for the product is the goal. Passing on the benefits of the new drug to a large number of patients does not matter, at all.

How credible is the industry argument?

In this context, let me take the example of Hepatitis C drug – Sovaldi of Gilead. Many now know that for each patient Sovaldi costs US$ 30,000 a month and US$ 84,000 for a treatment course.

According to an article published in Forbes, one health executive estimated that the annual price tag for Sovaldi could reach US$ 300 Billion because so many people have Hepatitis C infection worldwide.  This mindboggling amount is more than all spending on all drugs in the United States, currently.  A more realistic number might be between US$7 Billion and $12 Billion a year.  Even that amount is roughly five times the amount Gilead spends each year on research.

Like Sovaldi, in many other instances too, industry argument of recovering high R&D investment through product pricing would fall flat on its face.

Need to put all the cards on the table:

The distinguished author underscores in his article the expected responsibilities of the experts in this area to ask the global pharma industry to connect the dots for all us between:

  • The societal goals they aim to achieve
  • The costs they incur on R&D
  • The profits they should reasonably be earning.

Public investments in R&D:

Another article titled, “Putting Price On Life”, argues that R&D projects are mainly initiated in the public sphere through tax-funded research. Unfortunately, patients do not derive any benefit of these public investments in terms of reduction in prices for the related drugs. On the contrary, they effectively pay for these new products twice – once through tax-funded research and then paying full purchase price of the same drug.

Additionally, industry corners the praise for the work done by others in tax-funded research, while at the same time making R&D less risky, as public funded research groups carry out most of the initial risk prone and breakthrough innovation.

The article also highlights that global pharma companies receive other tax credits over billions of dollars for their expenditure on R&D. However, the R&D figures that are produced are not adjusted to take into account the tax credits, thereby inflating costs and the prices of drugs.

All these tax credits significantly lower the private costs of doing the R&D in the United States, increasing the private returns. Interestingly, there does not seem to be any public information regarding who gets the tax credit and what the credit is used for, while the government does not retain any rights in the R&D.

Does pharma R&D always create novel drugs?

According to a report, US-FDA approved 667 new drugs from 2000 to 2007. Out of these only 75 (11 percent) were innovative molecules having much superior therapeutic profile than the available drugs. However, more than 80 percent of 667 approved molecules were not found to be better than those, which are already available in the market.

Thus, the question that very often being raised by many is, why so much money is spent on discovery and development of ‘me-too’ drugs, and thereafter on aggressive marketing for their prescription generation? This is important, as the patients pay for the entire cost of such drugs including the profit, after being prescribed by the doctors?

Should Pharma R&D move away from its traditional models?

The critical point to ponder today, should the pharmaceutical R&D now move from its traditional comfort zone of expensive one company initiative to a much less charted frontier of sharing drug discovery involving many players? If this approach gains acceptance sooner, it could lead to significant increase in R&D productivity at a much lesser cost, benefiting the patients at large.

Finding the right pathway in this direction is more important today than ever before, as the R&D productivity of the global pharmaceutical industry, in general, keeps going south and that too at a faster pace.

Current IPR mechanism failing to deliver:

Current mechanism of Intellectual Property Rights (IPR), especially in the pharmaceutical space, undoubtedly facilitates spiraling high drug prices with no respite to patients and payers, as access to these drugs gets severely restricted to the privileged few, denying ‘right to life’ to many.

Moreover, the current global ‘Pharma Patent System’ does not differentiate between qualities of innovations. The system extends equal incentives for pricing the drugs as high as possible, even if those offer little advantages to patients. Fortunately, this loophole has been plugged in the Indian Patents Act 2005, to a large extent.

That said, there is no well-structured incentive available to develop clinically superior drugs with public funding, even in India, so that prices could be significantly lower with equally lesser risks to the companies too.

Conclusion:

Current pricing system of patented medicines is even more intriguing, as these have no direct or indirect co-relationship with R&D expenditures incurred by the respective players. On the contrary, drug prices allegedly go up due to other avoidable high expenditures, such as, physicians’ gratification oriented marketing, which includes even reported bribing, high profile political lobbying and private jet setting key executives lifestyle with exorbitant compensation packages, besides others.

To effectively address this issue, besides public R&D funding, there has been a number of suggestions for creation of a win-win pathway like, creation of “Health Impact Fund’. There are other inclusive, sustainable and cost effective R&D models too, such as ‘Open Innovation’ and ‘Accelerating Medicines Partnership (AMP)’, to choose from.

A recent HBR Article titled “A Social Brain Is a Smarter Brain” also highlighted, “Open innovation projects (where organizations facing tricky problems invite outsiders to take a crack at solving them) always present cognitive challenges, of course. But they also force new, boundary-spanning human interactions and fresh perspective taking. They require people to reach out to other people, and thus foster social interaction.” This articulation further reinforces the relevance of a new, contemporary and inclusive drug innovation model for greater patient access with reasonable affordability.

Be that as it may, ‘Patented Drug Pricing’ does not seem to have any relevance to a company’s investments towards R&D. On the contrary, the companies charge the maximum price that they could possibly handle to maximize profits on these life saving medicines.

In an environment of indifference like this, it is the responsibility of other stakeholders, especially the government, to ensure, by invoking all available measures, that life saving medications for dreaded diseases such as cancer, can get to those who need them the most, come what may.

Is the ever-alert new Government listening?

Is Drug Innovation As Critical As Access To Medicines For All? [Augmented By A Video]

To make important medicines available to all in a sustainable way, the renowned philosopher Thomas Pogge in this very interesting video clipping titled “Medicines For The 99 Percent” suggested the following three simple, yet critical, steps to effectively run the healthcare system of any nation with a cost-effective and patient-centric approach:

  • Access to important medicines for all
  • A robust drug innovation model to meet the unmet needs of patients
  • Transparent and efficient systems to make medicines affordable to all, eliminating wastage of all kinds

To translate this process into reality Pogge proposed an out-of-box model, not just to incentivize companies for drug innovation, but also to produce those drugs in a cost-effective way . In his submission, Pogge recommended a US$ 6 billion ‘Health Impact Fund’ to revolutionize the way medicines are developed and sold. He strongly argued that the value of an innovative drug should always be ascertained by its differential “Health Impact” on patients over the equivalent available generics in the respective disease areas.

As you will see in the video, the model is interesting and deserves wholehearted support from all stakeholders, despite possible resistance from some powerful quarters prompted by vested interests.

Drug innovation and access to medicines:

As the good old saying goes, “Health is Wealth”. When a person falls sick, regaining health is all-important. Medicines play a very critical role there, for all. In the ongoing battle against various types of diseases, addressing unmet needs of the patients is also equally important. For this reason, drug innovation plays just as critical a role.

However, it is now a well-known fact that medicines, as such, are not very expensive to manufacture on a relative yardstick. Abundant availability of cheaper generic medicines, post-patent expiry, with as much as  90 percent price erosion over the concerned patented drug price, would vindicate this point.

Current R&D model:

Astronomical mark-ups on the cost of goods for the innovative-patented drugs coming out of the current R&D model, restrict access to these medicines mostly to rich people of both poor and rich countries of the world, depriving majority of the have-nots. Although in an ideal situation, all these medications should be accessible to those who need them the most.

Is the model sustainable?

Innovator companies attribute ‘astronomical’ high prices of patented drugs to hefty R&D expenditure, which probably includes high cost of failures too. Unfortunately, despite ongoing raging debates, R&D expense details are still held very close to the chest by the innovator companies, with almost total lack of transparency. Many experts, therefore, believe that this opaque, skewed and unsustainable drug R&D model of the global pharma majors needs a radical makeover now, as you would yourself see by clicking on the ‘video clipping’, as mentioned above

To ensure full access to important drugs for all, there are other R&D or innovation models too. Unfortunately, none of those appears to be financially as lucrative to the innovator companies as the one that they are currently following, thus creating a challenging logjam in the inclusive process of drug innovation.

Are Pharmaceutical R&D expenses overstated?

Some experts in this area argue that pharmaceutical R&D expenses are overstated, as the real costs are much less.

An article titled “Demythologizing the high costs of pharmaceutical research”, published by the London School of Economics and Political Science in 2011 indicated that the total cost from the discovery and development stages of a new drug to its market launch was around US$ 802 million in the year 2000. This was worked out in 2003 by the ‘Tuft Center for the Study of Drug Development’ in Boston, USA.

However, in 2006 this figure increased by 64 per cent to US$ 1.32 billion, as reported by a large pharmaceutical industry association of the United States, though with dubious credibility as considered by many.

The authors of the above article had also mentioned that the following factors were not considered while working out the 2006 figure of US$ 1.32 billion:

▪   Tax exemptions that the companies avail for investing in R&D

▪   Tax write-offs that amount to taxpayers’ contributing almost 40 percent of the R&D cost

▪   Cost of basic research should not have been included as those are mostly undertaken       by public funded universities or laboratories

The article observed that ‘half the R&D costs are inflated estimates of profits that companies could have made, if they had invested in the stock market instead of R&D and include exaggerated expenses on clinical trials’.

“High R&D costs have been the industry’s excuses for charging high prices”:

In line with this deliberation, in the same article the authors reinforce the above point, as follows:

“Pharmaceutical companies have a strong vested interest in maximizing figures for R&D as high research and development costs have been the industry’s excuse for charging high prices. It has also helped generating political capital worth billions in tax concessions and price protection in the form of increasing patent terms and extending data exclusivity.”

The study concludes by highlighting that “the real R&D cost for a drug borne by a pharmaceutical company is probably about US$ 60 million.”

Should Pharmaceutical R&D move away from the traditional model?

Echoing philosopher Thomas Pogge’s submission, another critical point to ponder today is:

Should the pharmaceutical R&D now move away from its traditional comfort zone of expensive one company initiative to a much less charted frontier of sharing drug discovery involving many players?

If this overall collaborative approach gains broad acceptance and then momentum sooner, with active participation of all concerned, it could lead to substantial increase in R&D productivity at a much lesser expenditure, eliminating wastage by reducing the cost of failures significantly, thus benefiting the patients community at large.

Choosing the right pathway in this direction is more important today than ever before, as the R&D productivity of the global pharmaceutical industry, in general, keeps going south and that too at a faster pace.

Making drug innovation sustainable: 

Besides Thomas Pogge’s model with ‘Health Impact Fund’ as stated above, there are other interesting drug R&D models too. In this article, I shall focus on two examples:

Example I:

A July 2010 study of Frost & Sullivan reports: “Open source innovation increasingly being used to promote innovation in the drug discovery process and boost bottom-line”.

The concept underscores the urgent need for the global pharmaceutical companies to respond to the challenges of high cost and low productivity in their respective R&D initiatives, in general.

The ‘Open Innovation’ model assumes even greater importance today, as we have noted above, to avoid huge costs of R&D failures, which are eventually passed on to the patients again through the drug pricing mechanism.

‘Open Innovation’ model, as they proposed, will be most appropriate to even promote highly innovative approaches in the drug discovery process bringing many brilliant scientific minds together from across the world.

The key objective of ‘Open Innovation’ in pharmaceuticals is, therefore, to encourage drug discovery initiatives at a much lesser cost, especially for non-infectious chronic diseases or the dreaded ailments like Cancer, Parkinson’s, Alzheimer, Multiple Sclerosis, including many neglected diseases of the developing countries, making innovative drugs affordable even to the marginalized section of the society.

Android smart phones with huge commercial success are excellent examples of ‘Open Source Innovation’. So, why not replicate the same successful model of inclusive innovation in the pharmaceutical industry too?

Example II - “Accelerating Medicines Partnership (AMP)” initiative:

This laudable initiative has come to the fore recently in he arena of collaborative R&D, where 10 big global pharma majors reportedly decided in February 2014 to team up with the National Institutes of Health (NIH) of the United States in a ‘game changing’ initiative to identify disease-related molecules and biological processes that could lead to future medicines.

This Public Private Partnership (PPP) for a five-year period has been named as “Accelerating Medicines Partnership (AMP)”. According to the report, this US federal government-backed initiative would hasten the discovery of new drugs in cost effective manner focusing first on Alzheimer’s disease, Type 2 diabetes, and two autoimmune disorders: rheumatoid arthritis and lupus. The group considered these four disease areas among the largest public-health threats, although the span of the project would gradually expand to other diseases depending on the initial outcome of this project.

“A Social Brain Is a Smarter Brain”: 

As if to reinforce the concept, a recent HBR Article titled “A Social Brain Is a Smarter Brain” also highlighted, “Open innovation projects (where organizations facing tricky problems invite outsiders to take a crack at solving them) always present cognitive challenges, of course. But they also force new, boundary-spanning human interactions and fresh perspective taking. They require people to reach out to other people, and thus foster social interaction.” This articulation further reinforces the relevance of a new, contemporary and inclusive drug innovation model for greater patient access.

Conclusion:

Taking these points into perspective, I reckon, there is a dire need to make the process of offering innovative drugs at affordable prices to all patients absolutely robust and sustainable as we move on.

Philosopher Thomas Pogge, in his above video clipping, has also enunciated very clearly that all concerned must ensure that medications get to those who need them the most. He has also shown a win-win pathway in form of creation of a “Health Impact Fund’ to effectively address this issue. There are other inclusive, sustainable and cost effective R&D models too, such as Open Innovation and Accelerating Medicines Partnership (AMP), to choose from.

That said, a paradigm shift in the drug innovation model can materialize only when there will be a desire to step into the uncharted frontier, coming out of the comfort zone of much familiar independent money spinning silos of drug innovation. Dove tailing business excellence with the health interest of all patients, dispassionately, would then be the name of the game.

Bringing this transformation sooner is extremely important, as drug innovation would continue to remain as critical as access to important medicines for all, in perpetuity.

However, to maintain proper checks and balances between drug innovation and access to medicines for all, the value of an innovative drug should always be ascertained by its differential ‘Health Impact’ on patients over equivalent available generics in that disease area and NOT by how much money, including the cost of R&D failures, goes behind bringing such drugs to the market, solely driven by commercial considerations.
