From ‘Blockbuster Drugs’ to ‘Personalized Medicines’ – will it revolutionize the way the patients will be treated tomorrow?

Financial Times quoted Jeff Kendler, the CEO of Pfizersaying, “the era of dependence on a single or a couple of blockbuster drugs should be over. Lipitor sells U.S$ 12 billion a year. You can’t build a company predicted on the belief that you are going to find such a drug.”The argument is robust, what then are the alternatives?Rapid strides in pharmacogenomic bring in a promise of radically different way of treating diseases, as major pharmaceutical companies of the world make progress in developing much more effective medicines designed to target smaller populations. These medicines are termed as ‘personalized medicines’ and are expected to be an effective alternative to now quite unwieldy ‘blockbuster drugs’ business model.

In what way ‘Personalized Medicines’ will be different?

With ‘Personalized Medicines’ 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. Pharmacogenomic tests like, sequencing of human genome will determine a patient’s likely response to such drugs.

These are expected to offer more targeted and effective treatment with safer drugs, and presumably at a lesser cost. Such medicines will also help identify individuals prone to serious ailments like, diabetes, cardiovascular diseases and cancer and help physicians to take appropriate preventive measures, simultaneously. ‘Personalized medicines’ in that process will focus on what makes each patient so unique, instead of going by the generalities of a disease.

To give a 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.

‘Personalized medicines’, therefore, have the potential to bring in a revolutionary change the way patients are offered treatment by the medical profession. Genomic research will enable physicians to use a patient’s genetic code to arrive at how each patient will respond to different types of treatments.

In the field of cancer, genetic tests are currently being done by many oncologists to determine which patients will be benefitted most, say by Herceptin, in the treatment of breast cancer.

What is then the aim of ‘Personalized Medicines’?

The aim of ‘personalized medicines’ is 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, by 2010.

Expected benefits from ‘Personalized Medicines’:

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 Health care: ‘Personalized Medicines’ will enable the physicians to prescribe ‘the right dose of the right medicine the first time for everyone’. This would give rise to much better overall healthcare.

Role of Pharmaceutical and Biotech companies:

Many research based pharmaceutical and biotechnology companies have taken a leading role towards development of ‘personalized medicines’ in line with their key role as healthcare enterprises. India is also taking keen interest in this science.

Some important issues:

However, there are some ethical and social issues in the development of ‘personalized medicines’ primarily in the area of genetic testing and consideration of race in the development of such medicines, which need to be effectively addressed, sooner.

Can it replace the‘Blockbuster Drugs’ business model?

Realization of deficiencies in the economics of ‘block buster drugs’ R&D business model, has made ‘personalized medicines’ a reality today.

Improved efficacy and safety of treatment with ‘personalized medicines’ will prove to be cost-effective in healthcare systems. Smaller and exclusive markets for ‘personalized medicines’ are expected to be profitable for the pharmaceutical companies. But such smaller segmentation of the market may not leave enough space for the conventional ‘blockbuster model’, which is the prime mover of the global pharmaceutical industry, today.

Reports indicate that some renowned global pharmaceutical companies like, Roche, AstraZeneca, GlaxoSmithKline are making good progress towards this direction through collaborative initiatives.

Approximate cost of ‘Genome Sequencing’:

When human genome was first sequenced, the reported cost was staggering U.S$ 3 billion. However, with the advancement of technology, it came down to U.S$ 1 million, last year. Currently, the cost has further come down to U.S$ 60,000. With the rapid stride made in the field of biotechnology, combined with the economies of scale, cost of such genetic tests is expected to be around U.S$ 1,000 in near future, making it possible for people to obtain the blue print of their genetic code.

Savings on cost of Clinical trials with ‘Personalized Medicines’:

Genome sequencing will help identifying a patient population, which will be far more likely to respond positively to the new treatment. In that process, if it reduces costs of clinical trial by even 5%, expected net savings for the industry towards clinical trial have been reported to be around U.S$ 5 billion.

With ‘personalized medicines’ the innovator companies will be able to significantly reduce both time, costs and the risks involved in obtaining regulatory approvals and penetrating new markets with simultaneous development of necessary diagnostic tests. Such tests will be able to identify patients group who will not only be most likely to be benefitted from such medicines, but also will be least likely to suffer from adverse drug reactions.

Therefore, considerable cost advantages coupled with much lesser risks of failure and significant reduction in the lead time for clinical trials are expected to make ‘personalized medicines’ much more cost effective, compared to conventional ‘blockbuster drugs’.

Innovative and cost effective way to market ‘Personalized Medicines’:

With ‘personalized medicines’ the ball game of marketing pharmaceuticals is expected to undergo a paradigm shift. Roche’s model of combining necessary diagnostic tests with new drugs will play a very important role in the new paradigm.

Roche is ensuring that with accompanying required diagnostic tests, the new oncology products developed at Genentech can be precisely matched to patients.

Can ‘Personalized Medicines’ be used in ‘Primary Care’ also?

To use ‘personalized medicines’ in a ‘primary care’ situation, currently there is no successful model. However, it has been reported that in states like, Wisconsin in the U.S, initiative to integrate genomic medicines with ‘primary care’ has already been undertaken. Scaling-up operations of such pilot projects will give a big boost to revolutionize the use of ‘personalized medicines’ for precision and targeted treatment of the ailing population.

In my view, there does not seem to be any possibility of looking back now. The robust business model of ‘personalized medicines’, is now the way forward, as much for the industry as for the patients. It is a win-win game.

Improving ‘Access to Modern Medicines’ in India –Public Private Partnership (PPP) is the way forward.

Despite various measures being taken by the Government of India (GoI) from time to time, around 65% of Indian population are not having access to modern medicines. It appears, GoI is of the view that the reason for poor ‘access to modern medicines’ to a vast majority of our population is intimately linked to the issue of ‘affordability of medicines’.To make medicines affordable to the common man, the Government took a radical step in 1972 by passing a law to abolish products patent in India. The change in paradigm at that time, encouraged domestic pharmaceutical players to manufacture and market even those latest and innovative drugs, which were protected by patents, n many countries of the world. The new ball game enabled the domestic players to highly specialize in ‘reverse engineering’ and launch generic versions of most of the New Chemical Entities (NCEs)at a fraction of the innovators price, in India.This shift in Paradigm in 1972, catapulted the Indian domestic pharmaceutical industry to a newer orbit of success. India in that process, over a period of time, established itself as a major force to reckon with, in the generic pharmaceutical markets of the world. Currently, the domestic pharmaceutical industry in India caters to around one third of the global requirement of generic pharmaceuticals.

From 1972 to 2005 domestic Indian pharmaceutical companies focused on replicating all most all blockbuster drugs, like for example, major Cox2 inhibitors (Merck and Pfizer), Viagra and Lipitor (Pfizer) etc, to low price generic substitutes and that too just within a year or two from the date of first launch of these products in the developed markets of the world.

In 1972, the Market share of the Indian domestic companies, as a percentage to turnovers of the total pharmaceutical industry of India, was around 20%. During the era of ‘reverse engineering’, coupled with many top class manufacturing and marketing strategies, domestic Indian pharmaceutical players wheezed past their multinational (MNCs) counterparts in the race of market share, exactly reversing the situation in 2009.

‘Reverse engineering’ was one of the key growth drivers of domestic pharmaceutical industry during this period. In its absence, during post IPR regime, the growth rate of branded generic industry is not expected to be as spectacular. However, the low cost ‘essential medicines’ will continue to be produced and marketed in India in future, as well.

Be that as it may, from 1972 to 2005, India could produce and offer even the latest NCEs, at a fraction of their international price, to the Indian population. There were as many as 40 to over 60 generic versions of each successful blockbuster drug of the world, in India. Cut-throat competition was intense and still it is, which keeps the average price of such medicines well under control. To further tighten its grip over pharmaceutical products pricing, GoI imposed stringent price control and price monitoring mechanism simultaneously, which are in place even today. Despite competitive pricing pressure coupled with Government price control, over nearly four decades, with a key policy focus on ‘affordability of medicines’, why then ‘access to modern medicine’ remained abysmal for a vast majority of the population of India?

To address this vexing problem, Industry Associations reported to have suggested a policy shift towards public-private-partnership (PPP) model to the Ministry of Chemicals and fertilizers in 2006-07. At that time, the Associations seem to have offered that the Pharmaceutical Industry will supply to the GoI the essential medicines at 50% of their Maximum Retail Price (MRP), to cater to the need of the common man, especially those who are below the poverty line (BPL).

However, to make this proposal effective there is a fundamental need for the Government to quickly initiate significant ‘capacity building’ exercise, initially in our primary and then in the secondary healthcare value chain. Towards this direction, the Federation of Indian Chambers of Commerce and Industry (FICCI) reported to have suggested to the Government for an investment of around US$ 80 billion to create over 2 million hospital beds.

Frugal budget allocation (1.12%) of the GoI towards healthcare as % of GDP of the country, suggests that Government is gradually shifting its role in this very important area, primarily from healthcare provider to healthcare facilitator for the private sectors to develop it further. In such a scenario, it is imperative for the government to realize that the lack of even basic primary healthcare infrastructure, leave aside other incentives, impede effective penetration of private sectors into semi-urban and rural areas. PPP model should be worked out to address such issues, effectively.

I have highlighted the remedial measures to be taken to address this situation in my article, which can be read by clicking on the following link:

http://www.tapanray.in/profiles/blogs/65-of-indians-do-not-have

Over 70 percent of our population are located in rural India. A relatively recent study indicates that despite some major projects undertaken by the Governments, like National Rural Health Mission (NRHM), about 80 percent of doctors, 75 percent dispensaries and 60 percent of hospitals are located in urban India. Another recent initiative taken by the Department of Pharmaceuticals (DoP) called ‘Jan Aushadhi’ is also orientated towards urban and semi-urban India.

I had deliberated upon the ways to increase penetration of ‘Jan Aushadhi’ in rural India, in another article, which can be read by clicking on the following link:

http://www.tapanray.in/profiles/blogs/jan-aushadhi-medicines-for

The net result of such policy initiatives, denies over 65 percent of Indian rural population from having access to quality healthcare services. Such lack of focus on rural areas, perhaps will explain the reason why only 35 percent of Indian population is having access to modern medicines.

Instead of trying to find a solution for this alarming ‘access to medicines’ problem, by limiting focus mainly on the issue of ‘affordability’ of medicines, for several decades, the Government is doing a great disservice to the common man, mainly located in the rural and semi-urban India. It is now high time that the GoI analyzes the available data to address the root cause of poor healthcare delivery, infrastructure and almost total lack of healthcare financing for all strata of Indian society.

Let me hasten to add that in no way I am trying to say that ‘affordability of medicines’ is no issue in India. All I am saying is that an integrated approach towards the root causes will quite effectively take care of ‘affordability’ issue and NOT the vice versa.

Even a problem of such magnitude can be converted into an opportunity. India can certainly be made a global hub for quality and affordable healthcare services, flashes of which we see in medical tourism initiatives.

Therefore, to address the acute problem of ‘access to modern medicines’ to a vast majority of the Indian population, GOI should reach all out to attract significant private and even foreign direct investments (FDI) through innovative Private Public Partnership initiatives. A strong will to have an ‘out of box’ solution to this critical problem is the crying need of the hour.

Despite so much of stringent government control, debate and activism on the affordability of modern medicines in India, on the one hand, and the success of the government to make medicines available in the country at a price, which is cheaper than even Pakistan, Bangladesh and Sri Lanka, on the other, the fact still remains, about 65% of Indian population do not have access to affordable modern medicines, compared to 15% in China and 22% in Africa.The moot question therefore is, despite all these stringent price regulation measures by the government and prolonged public debates over nearly four decades or so to ensure better ‘affordability of medicines’, why then the situation on ‘access to modern medicines’has remained so abysmal to a vast majority of the population, in India?This, in my view, is mainly because; no single minister or ministry can now be held accountable by the civil society for such a dismal performance in the access to healthcare, in India.

Poor healthcare infrastructure:

As per the Government’s own estimate, India records:

1. A shortage of 4803 Primary Health Centres (PHC)

2. A shortage of 2653 Community Health Centres (CHC)

3. No large Public Hospitals in rural areas where over 70% of the populations live

4. Density of doctors in India is just 0.6 per 1000 population against 1.4 and 0.8 per 1000 population in China and Pakistan respectively, as reported by WHO.

The Government spending in India towards healthcare is just 1.1% of GDP, against 2% by China and 1.6% by Sri Lanka, as reported by the WHO.

Some good but sporadic public healthcare initiatives:

The government allocation of around US$ 2.3 billion for the National Rural Health Mission (NRHM), is a good initiative to bring about uniformity in quality of preventive and curative healthcare in rural areas across the country.
While hoping for the success of NRHM, inadequacy of the current rural healthcare infrastructure with about 80 percent of doctors, 75 percent dispensaries and 60 percent of hospitals located only in the urban India, may encourage skepticism.

Addressing the issue of improving access to healthcare:

While addressing the issue of improving access of healthcare, following three important ‘Public Private Partnership (PPP)’ initiatives would be most appropriate.

1. PPP to improve affordability:

To address this vexing problem, industry associations had jointly suggested a policy shift towards public-private-partnership (PPP) model to the government in 2006-07, instead of a stringent price control mechanism, which has not worked thus far to improve access of modern medicines, in India. Instead, the associations seemed to have suggested that the pharmaceutical industry will supply to the government the essential medicines at 50% of their Maximum Retail Price (MRP), to cater to the need of below the poverty line (BPL) families.

It is worth mentioning, many OPPI member companies like, Novartis, GSK, Pfizer, Sanofi-Aventis etc. have their own access to medicines programs in India.

Although the government did not respond to this proposal, to make it effective the ministry of health will require to quickly initiate significant ‘capacity building’ exercises, both in the primary and also in the secondary public healthcare facilities in the country. FICCI is reported to have suggested to the Government for an investment of around US$ 80 billion to create over 2 million hospital beds, for such capacity building exercises .

Frugal budget allocation by the government towards healthcare of the country, suggests that Government is gradually shifting its role in this very important area, primarily from healthcare provider to healthcare facilitator for the private sectors to develop it further. If it is so, it is imperative for the government to realize that the lack of even basic primary healthcare infrastructure, leave aside other incentives, impede effective penetration of private sectors into semi-urban and rural areas. Effective PPP model should be worked out to address such issues, without further delay.

2. PPP to leverage the strength of Information Technology (IT) to considerably neutralize the system weaknesses:

Excellence in ‘Information Technology’ (IT) is one of the well recognized strengths that India currently possesses. This strengths needs to be adequately leveraged through PPP to neutralize the above weaknesses. Harnessing IT strengths, especially in the areas of drug procurement and delivery processes, especially in remote places, could hone the healthcare delivery mechanism, immensely.

Another IT enabled technology that India can widely use across the nation to address rural healthcare issues is ‘‘Telemedicine’ for distant diagnosis and treatment of ailments. Required medicines for treatment could be made available to the patients through ‘Jan Aushadhi’ initiative of the Department of Pharmaceuticals (DoP), by utilising the Government controlled distribution outlets like, public distribution system (ration shops) and post offices, which are located even in far flung and remote villages of India.

3. PPP in healthcare financing for all:

Unlike many other countries, even as compared to China, over 72 percent of Indian population pay out of pocket to meet their healthcare expenses.

Out of a population of 1.3 billion in China, 250 million are covered by insurance; another 250 million are partially covered by insurance and balance 800 million are not covered by any insurance. Converse to this scenario, in India total number of population who may have some sort of healthcare financing coverage will be around 200 million with penetration of health insurance at just around 3.5% of the population. India is fast losing grounds to China mainly due to better response to healthcare infrastructure.

Even after leveraging IT for ‘Telemedicine’ and improving healthcare delivery processes, together with availability of low priced quality medicines from ‘Jan Aushadhi’ outlets, a robust healthcare financing model for all strata of society to make healthcare products/services affordable to a vast majority of the population, will remain an essential requirement for the country to address the issue of improving access to healthcare to all.

According to a survey done by National Sample Survey Organisation (NSSO), 40% of the people hospitalised in India borrow money or sell assets to cover their medical expenses. A large number of populations cannot afford to pay for the required treatment, at all.

Conclusion:

In my view an integrated approach for creating effective healthcare infrastructure throughout the country, leveraging IT in the entire healthcare space, appropriately structured ‘Health Insurance’ schemes for all strata of society ably supported by well spread out ‘Jan Aushadhi’ outlets even in far flung rural areas, deserve careful consideration by the Government.

A PPP model in all these three areas needs to be worked out in detail to address the pressing issue of improving ‘Access to Affordable Integrated Healthcare to ALL’.
