Research and Development (R&D) initiatives, though very important for most of the industries, is the life blood for the pharmaceutical sector, across the globe, to meet the unmet needs of the patients. Thus, very rightly, the Pharmaceutical Industry is considered as the ‘lifeline’ for any nation, in the battle against diseases of all types.

Drugs and Pharmaceuticals not only cure diseases and improve the quality of life of patients, but also help reducing the ‘burden of disease’ significantly. A study on five illnesses like AIDS, Cardiovascular, Cancer, Alzheimer’s and Rheumatoid-arthritis showed that drug research will save more than US$ 750 Billion in the treatment costs alone _[1].

Similarly, treatment with drugs for schizophrenia can save more than US$ 70,000 per patient per year, due to avoidable hospitalization _[2]. All these highlight the critical role that R&D could play in the healthcare system of any country.

R&D is not a threat to cheaper generic medicines:

More number of incoming patented medicines from the R&D labs will ensure faster growth of the generic pharmaceutical industry too, after the former will go off-patent. Even in the USA, which offers the highest number of innovative medicines across the globe, has a vibrant high growth generic pharmaceutical industry in place. The market penetration of cheaper generic drugs in the US is amongst the highest in the world and stands at more than half of all prescription medicines.

R&D process:

Over the years, pharmaceutical R&D process, though has evolved into a highly sophisticated and complex science, it still calls for enormous resources in terms of money, materials and skilled manpower, besides years of precious time.

Over a period of so many years, the small-molecule blockbuster drugs business model made pharmaceuticals a high-margin industry. However, it now appears that the low hanging fruits to make blockbuster drugs have mostly been plucked.

These low hanging fruits involved therapy areas like, anti-ulcerants, anti-lipids, anti-diabetics, cardiovascular, anti-psychotic etc. and their many variants, which were relatively easy R&D targets to manage chronic ailments. Hereafter, the chances of successfully developing drugs for cure of these chronic ailments, with value addition, would indeed be a very tough call. Even in this environment, India’s investment in R&D still remains very modest by the international standard.

Global R&D investment and Asia-Pacific Region:

It has been reported that in the global pharmaceutical industry_[3] 85 % of the medicines are produced by North America, Europe, Japan and Latin America and the developed nations hold 97% of the total patents worldwide.

Unlike the common perception, that China is attracting a significant part of the global investments towards R&D, latest data of MedTRACK revealed that only 15% of all drugs development is taking place in Asia-Pacific, despite the largest growth potential of the region in the world.

The key growth driver of any economy:

Innovation being one of the key growth drivers for the knowledge economy, creation of innovation friendly ecosystem in the country calls for a radical change in the mind set – from ‘process innovation’ to ‘product innovation’, from ‘replicating a molecule’ to ‘creating a molecule’.  A robust ecosystem for innovation is the wheel of progress of any nation.

It is encouraging to hear that the Government of India is working towards this direction in a more elaborate manner in its 12^th Five Year Plan.

Indigenous capability for production of the country must give way to indigenous capability for innovation and discovery.  Laws and policies need to facilitate, reward, recognise, protect and encourage all those who are or could be a part of this critical process.

Striking a right balance between the cost of research and affordability of medicines:

While the common man expects newer and better medicines at affordable prices, the Pharmaceutical Industry has to battle with burgeoning R&D costs, high risks and increasingly long period of time to take a drug from the ‘mind to market’, mainly due to stringent regulatory requirements. It will indeed be a very proud moment for India, when a drug, especially, for treating Non-infectious Chronic Diseases (NCD) comes out of its home-grown R&D centers.

R&D is an arduous process:

The dynamics of Drug Discovery are shown below:

• Despite patent life being 20 years, effective period of exclusivity for the discoverer is only 7.5 – 8.5 years.

•  Another report, as depicted in the chart below indicates the investment pattern in R&D by various countries in the developed markets of the world:

Where does the money go? (%)

Where does the R&D investment go? (%)

Looking at the long lead time before a new drug starts paying back and even if net profitability of 50% on sales are permitted, recovery of the entire R&D cost only from the Indian market would be virtually impossible.  Hence, if Indian R&D is to pay back, we need to have access to overseas markets.

Harmonization of regulatory standards is a must for containment of R&D costs.  Researchers in the country are currently following the ‘DRL’ or ‘Glenmark’ model of selling /out licensing the discovery for offshore development.

Strengths and weaknesses of India in Pharmaceutical R&D:

Following are the current strengths and weaknesses of the Pharmaceutical Industry of India from the R&D perspective:

Strengths:

• Mature Industry with strong manufacturing base
• Strengths in (innovative) process chemistry
• Abundance of raw talent
• Entrepreneurial spirit
• Highly talented and skilled Indian scientists working abroad (great potential for networking)
• Low cost of Manpower
• Cost effective Manufacturing Facilities
• Rich Biodiversity
• Global Clinical Trials are now being contacted in India

Weaknesses:

• Lack of funding and resources
• Lack of a ready ‘talent pool’
• Low profile of high quality work being carried out
• Inadequate regulatory framework / infrastructure
• Low investment in R & D
• Missing Link between Research and Commercilisation

Research Options for India:

Following are various research options available to India:

• Basic Discovery Research:

Basic Discovery Research is capital intensive, costly and takes a long time for the return on investments.  This could be made possible only if significant (NIH-type) funding is available.

• Genetic & Proteomic Research:

Genetic and Proteomic Research involves many of these following procedures:

- Decoding Human Genetic Code

- Identification of Genetic Markers

- Personalized cards or chips that will contain each person’s genetic structure

- Genetic Manipulation to alter a person’s susceptibility to a particular disease

- Elimination of therapies that will not work on certain genotypes

This is probably the most exciting field of Research today, where the Industry will be able to “leap-frog” given the right priority.  The International Center of Genetic Engineering and Biotechnology (ICGEB) is already a recognized center of excellence both within and outside the country.  Hence international grants and funding must be aggressively pursued.

• Biotechnology  & Biosimilars:

Biotechnology & Biosimilar drugs could be yet another opportunity area for India to leapfrog.  Biotech derived products are among the fastest growing in the world. These products being more expensive, if discovered and developed locally, could be affordable to many and also highly profitable.  Immunological and DNA Vaccines could be the most cost-effective answer to healthcare problems in developing countries, including India and should, therefore, be given top priority.  Here again, collaborative and international grants will be a critical success factor, just as the success of Biotech Companies in the US was fuelled by private venture capital.

• Process Research:

While focusing on Product Research, the Process Research should not be ignored, as India possesses considerable skill base for this type of research, even better than China.  Cost effective, more and more economical processes will always be necessary to make products more and more affordable to patients.

• Natural Product Screening:

India’s rich bio-diversity should not go waste.  The amount of work being done today is negligible as compared to the availability of “raw material” from the natural source.  Indian bio-diversity should be captured and cataloged into a meaningful library to facilitate R&D in this area.

• The ‘Open Innovation’ Model:

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

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

Other Areas:

• Epidemiological Research: The Industry needs good reliable data on the burden of human diseases.  In the absence of this data, it will be difficult to allocate resources and predict outcomes of new therapies.
• Clinical Research (including toxicological / animal testing):  This area needs to be made world class, sooner than the later, not only to bring down the cost of drug development, but also to ensure that the data thus produced are acceptable in other countries.  India has the potential to emerge as the most sought after global hub for pre-clinical and clinical drug development processes.

Basic pre-requisites to encourage R&D in India:

• Innovation friendly ecosystem
• Adequate Funding
• World class Infrastructure
• Ready talent pool

The key elements of creating an ecosystem conducive to R&D:

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

Key role of Universities:

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

R&D funding:

Access to world markets is the greatest opportunity in the entire process of globalisation and the funds available abroad are a valuable source of “funding” to boost R&D in India. Inadequacy of funding is the greatest concern.

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

1. Self-financing Research: This is based on (i) “CSIR Model” i.e. recover research costs through commercialization – collaboration with industries to fund research projects and (ii) “Dr Reddy’s Lab / Glenmark Model” i.e. recover research costs by selling lead compounds without taking through to development – wealth creation by the creation of Intellectual Capital.
2. Overseas Funding:  By way of joint R&D ventures with overseas collaborators; seeking grants from overseas Health Foundations; earnings from Contract Research as also from Clinical Development and transfer of aborted leads (‘Killing Fields” of the West) and collaborative projects on Orphan Drugs.  Multinational companies could be encouraged to deploy resources, as this is where the real money is.
3. Venture Capital & Equity Market :  This could be both via Private Venture Capital Funds and Special Government Institutions.  If regulations permit, foreign venture funds may also wish to participate. Venture Capital and Equity Financing will emerge as important sources of finance once track record is demonstrated and ‘early wins’ are recorded.
4. Fiscal Support & Non-Fiscal Support: Will also be valuable in early stages of R&D, for which a variety of schemes are possible as follows:

• Customs Duty Concessions: For Imports of specialised equipment, e.g. high throughput screening equipment, equipment for combinatorial chemistry, special analytical tools, specialised pilot plants, etc.
• Income tax concessions (weighted tax deductibility): For both in-house and sponsored research programmes.
• Soft loans: For financing approved R&D projects from Government financial institutions / banks.
• Tax holidays: Deferral, loans on earnings from R&D.

Government funding: Government grants though available, tend to be small and typically targeted to government institutions or research bodies. There is very little government support for private sector R&D.

All these schemes need to be simple and hassle free and the eligibility criteria must be tight.

Infrastructure for R&D:

Scientific infrastructure needs of the country require to be urgently strengthened.  Many of our Research Institutions require immediate upgradation.  All research laboratories should be encouraged to be profit driven and plough back earning in modernization.

Quality of life (proximity to schooling, hospitals, recreation) and ambiance is important, particularly for scientists working abroad, who could be encouraged to return to India.

Setting up of world class Clinical Pharmacology Laboratories and Toxicology Centers must be considered.  All clinical trials carried out in India must conform to GCP standards.  At the same time, Indian registration procedures should be harmonized and simplified in order to minimize duplication of efforts and time loss.

Indian Patent infrastructure:

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

• Enhancing patent literacy both in Legal and Scientific Communities, who must be taught how to read, write and file a probe.
• Making available appropriate Search Engines to our scientists to facilitate worldwide patent searches.
• Creating world class Indian Patent Offices where the examination skills and resources will need considerable enhancement.
• Advisory Services on Patents to Indian scientists to help in filing patents in other countries.

Partnering for Drug Discovery:

Many Indian pharma companies have entered into international collaborative arrangements, including R&D for development of new drugs for disease areas like cancer, diabetes, malaria and nervous system disorders.

DRL has partnered with ClinTec International for clinical trials and co-development of its anti-cancer drug. ClinTec International will possess the marketing rights for European markets while the commercialization for the rest of the world and US markets would be retained by DRL. It has also tied up with Torrent Pharma for the exclusive marketing rights of its two hypertension drugs in Russia, where Torrent has a strong market hold.

GSK and Ranbaxy set up an early-stage partnership in drug research, under which GSK will provide the Indian firm with leads, Ranbaxy will conduct lead optimization and animal trials, and GSK will take the drug through human trials. GSK will have exclusive rights to sell any resulting product in developed-world markets, and the two firms will co-promote it in India.

Conclusion:

- It is essential to have balanced policies offering equitable advantage to all stakeholders, including patients.

- Globalization brings opportunities like, access to markets, which are far more profitable than ours.  Any policy of isolation or retaliation in an increasingly more global environment, could go against the general interest of the country.

- Acceptance by the Government of the benefits of privatization, market liberalization and rationalization of Government controls, will add speed to R&D initiatives.

- The trade policy is another important ingredient of public policy which can either reinforce or retard R&D efforts.

- Empirical evidence across the globe has demonstrated that a well balanced patent regime in the country encourages the inflow of technology, stimulates research and development, benefits both the national and the global pharmaceutical sectors and most importantly benefits the healthcare system.

- The Government, academia, scientific fraternity and the Pharmaceutical Industry should get involved in various relevant Public Private Partnership (PPP) arrangements for R&D to ensure wider access to newer and better medicines in the country, providing much needed stimulus to the public health interest of the nation.
