Create Greater Patient–Value To Excel With Repurposed Covid Brands

Posted on by

Regular introduction of new molecules, line extensions or a Novel Drug delivery System (NDDS) has remained the life blood for pharma to rejuvenate a company’s product portfolio for driving organizational growth. But, Covid’s unprecedented and devastating assault on human lives and livelihoods, has pushed many of these initiatives off track. Covid infection was declared pandemic by the World health organization (WHO) on March 11, 2020, compelling the industry to primarily focus on finding solutions for survival, especially in the product development areas.

As the fight against time, the need for survival became so intense, there was no time for pharma companies going back to primary research, to discover new effective Covid specific drug molecules. Vaccines – at the initial stage of the pandemic, were considered by experts could be the only ‘magic bullet’, to get the humanity back again on its feet, after a fierce knockout blow by the virus. As on date, although vaccines seem to be nearer the finishing line of creating adequate initial immunity against Covid, still there are no scientifically proven drugs to predictably cure this infection.

Meanwhile, the focus of all concerned is on the existing drugs, to examine their effectiveness against Covid-19. Accordingly, right from hydroxychloroquine, dexamethasone to a number of already existing antiviral agents were repurposed for Covid treatment, under emergency approval by country regulators, pending detailed clinical trials.

For various critical reasons, experts now feel that the use various NDDS technologies in repurposing existing drugs, would create greater value for patients in Covid treatment. At the same time, this will help pharma companies to create a cutting-edge differentiator for their repurposed brands – being more patient centric. In this article, I shall dwell in this area, starting with the current status and issues with repurposed Covid drugs, as of date.

Current status and issues with repurposed Covid drugs:

According to recent reports, such as one titled ‘Formulation and delivery strategies for COVId-19 drugs,’ published by the AIchE in June 2020, more than 40 different drugs are currently being explored for efficacy against COVID-19. Unfortunately, side effects of many of these repurposed drugs limit their use in most severe cases, besides preventing their use as prophylactics.

A large proportion of repurposed Covid drugs are small-molecule medications, antivirals, and immune-modulating antibodies. These are already approved for other indications (like hydroxychloroquine, ribavirin, favipiravir), or under clinical trials, but not yet approved by the U.S. Food and Drug Administration, FDA (like, remdesivir, galidesivir, leronlimab).

If proven effective, these drugs would offer several advantages from a rapid- response perspective, such as the availability of safety data. In addition, several of these drugs offer broad-spectrum activity that makes it more likely they will remain functional even if the SARS-CoV-2 virus mutates. However, there are also exists some critical issues with repurposed Covid drugs.

Some critical issues with repurposed Covid drugs:

Let me cite below two examples, just to drive home the point of some critical medical issues, now existing with these repurposed Covid drugs:

  • Hydroxychloroquine – the malaria drug, when used as directed, commonly produces nausea, diarrhea, vomiting, besides muscle weakness. Importantly, at higher concentrations – only two to three times the daily dose, it can cause potentially fatal acute cardiovascular toxicity. Thus, the possibility of severe side effects makes the drug unattractive as a preventive measure. Drug formulation and delivery strategies, such as controlled release and targeted delivery could expand the use of such existing drugs, the report recommends.
  • The HIV drug combination lopinavir and ritonavir, which is under evaluation as a COVID-19 treatment, has side effects that include diarrhea, nausea, and liver damage. With a half-life of about 4–6 hours, the systemic concentrations can vary by a factor of eight between peak and trough. Developing a controlled-release formulation that maintains the minimum effective drug concentration, could mitigate side effects by reducing the steady-state drug concentration by as much as eightfold and reducing the burden on the liver by 81%, the above study, published by the AIchE in June 2020, highlighted.

At this point, for greater clarity, let me recapitulate what NDDS really means.

NDDS – clinical and marketing relevance:

Novel Drug Delivers Systems or NDDS generally ‘refers to the approaches, formulations, technologies, and systems for transporting a pharmaceutical compound in the body as needed to safely achieve its desired therapeutic effects.’

This process was lucidly explained in a contemporary article, which also inferred that the method by which a drug is delivered can have a significant effect on its efficacy and safety profile.

Yet another paper underscored, ‘if therapeutic agents can be made more efficacious and safer, using an improved drug delivery system, could achieve both –lucrative marketing opportunities for pharmaceutical companies, alongside advancement in the treatment of diseases of mankind.’ Moreover, NDDS can also help maintain the drug concentration in the therapeutic range for a longer period of time and deliver the content to the site of action if required.

Leaving aside the technical details behind these mechanisms let me underscore - that NDDS will be a boon for the repurposing of drugs, was also discussed in detail in an article titled, ‘Role of Novel Drug Delivery Systems in Coronavirus Disease-2019 (COVID-19): Time to Act Now,’ published on September 09, 2020.

Some broad categories of NDDS and new initiatives:

For this purpose, some of the broad categories of NDDS may include the following:

  • Sustained- or controlled drug delivery systems provide drug action at a pre-determined rate.
  • Localized drug delivery devices for drug release in the vicinity of the target.
  • Rate – pre-programed drug delivery systems.
  • Targeted drug delivery provides drug action by using carries, which recognize their receptor at the target.

It goes without saying that NDDS mechanism may be used both for new molecules that may eventually be developed, and also for the existing repurposed drugs for Covid treatment.

Some encouraging initiatives of NDDS for Covid drugs:

The encouraging news is pharma initiatives in this regard has already commenced. For example, unprecedented interest in inhaled delivery of antiviral drugs has led to Aerogen’s involvement in multiple COVID-19 drug development initiatives, with more than 15 leading pharmaceutical companies - worldwide.

Several of these collaborations are already in clinical trials. Others are also on track to enter studies on moderately and severely ill COVID-19 patients, the Press Information of Aerogen dated October 22, 2020 highlighted. Let me cite below two more examples in this area, to explain the intensity of work that has commenced in the NDDS space for repurposed Covid drugs.

Covis Pharma’s inhaled glucocorticoid, Alvesco (ciclesonide) has entered Phase III safety and efficacy trial in 400 non-hospitalized patients  -12 years of age and older with symptomatic COVID-19. The product is delivered twice daily via a pressurized metered dose inhaler (pMDI).

Senzer Pharmaceuticals - a UK based company, is also in the process of formulating two specific medicines with antiviral properties, to allow them to be inhaled directly into the respiratory tract. The primary aim is to reduce the number of COVID-19 patients requiring intensive care treatment. Senzer is also using a pMDI for targeted drug delivery of actives through inhalation, as it offers potential advantages over oral intake. These include, ease of administration, assisting early treatment, allowing a lower dose by reducing unwanted side effects and supporting the safety profile of the products.

Experts consider preparations of inhalable particles for local delivery is a simpler approach. This is because the lungs comprise only about 2% of the total body weight, targeted delivery could reduce the amount of drug required by a factor of 50 or more, as compared to oral administration.

Be that as it may, the primary purpose of all such initiatives is to ensure more effective and safer drug delivery to Covid patients. It is now up to the pharma marketing leadership to ascertain how to leverage such NDDS opportunities to deliver extra patient-value, simultaneously creating a cutting edge for marketing these repurposed brands.

Impact of Covid on the NDDS market segments:

The May 11, 2020 report titled, ‘Drug Delivery Systems Market Forecast, Trend Analysis & Competition Tracking – Global Market Insights 2020 to 2025,’ presents some interesting details in this area. It forecasts, the global drug delivery systems market shall register an upswing, expanding at a strong CAGR of 7.0% during the forecast period (2020-2025).

The ongoing COVID-19 pandemic is expected to further heighten prospects of NDDS, with the number of infections still increasing every day. Consequently, many leading pharma companies have accelerated production of essential drug delivery systems, as stated above. According to the above report, the key growth drivers of the NDDS market include:

  • Targeted drug delivery - being most dominant, is expected to capture nearly half of the global NDDS market, expanding at a healthy CAGR of 6.8% across the above forecast period.
  • Polymeric drug delivery segment is anticipated to be the second-most lucrative area, expanding at a CAGR of 7.3% across the forecast period. The popularity of this delivery type is attributed to its efficiency in localized drug delivery in large amounts, alongside lowering drug toxicity rate. The polymeric drug delivery segment is expected to capture more than 1/3rd of the global drug delivery systems market during the forecast period.
  • Application of nanotechnology is another key growth determinant for the segment. Insertion of nanoparticles help penetrate the targeted tissue in a much better manner. These particles are easily absorbed by cells, facilitating efficient drug delivery.
  • Microneedle drug delivery helps deliver vaccines or other drugs across various barriers.

Conclusion:

The Covid clock keeps ticking. As on November 22, 2020 morning, India recorded a staggering figure of 9,095,908 of Coronavirus cases with 133,263 deaths. The average number of daily new cases appeared, after the festive season, have started climbing up again. The threat of subsequent waves for further spread of Covid infection now looms large.

In this regard, many experts initially thought that Covid vaccines will be magic bullets to win the war against the new Coronavirus. But in the most recent times, this situation has changed, and it is no longer so – not even Pfizer vaccine. Indian media also deliberated the same on November 05, 2020.

Under this backdrop, Arthur L. Caplan, professor of bioethics at New York University’s Grossman School of Medicine, who wrote a 2017 book on vaccine ethics and policy have also made a profound comment. He said recently: “We’re going to have to continue our behavioral efforts - the masking and distancing and the quarantining and the testing and so on — in parallel with vaccination because it would be very, very surprising if we got a very highly effective vaccine first one out of the box.”

Currently, the world doesn’t have any clinically proven new Covid treatment drugs, either. What we have now is a number of repurposed Covid drugs, many of these are in advanced stage of clinical trials. As and when these are approved by the country’s regulators, pharma marketers will have a task cut to excel with those – among many ‘me-too’ types. In this scenario, there will be a critical need to create greater patient-value with a company’s own repurposed brand, where right application of NDDS technology could play a game changing role. The time to keep pondering is over. Time to decide is – now.

‘Rigged’ Payment System Limits Biosimilar Access

Posted on by
Reply

As often discussed, market entry of biosimilars, in general, brings a new hope not just for many patients, but also to biosimilar drug manufacturers – planning to get marketing approvals of these drugs in the United States, the El Dorado of global pharma industry.

Stakeholder expectations keep increasing manifold as biosimilars offer cheaper treatment options with biologic drugs in many life-threatening and rare diseases. However, biosimilars still remain an unfulfilled promise.

The January 2018 paper by Trinity Partners on “The State of US Biosimilars Market Access” in the largest drug market of the world makes an important observation in this regard. It says, the promise of biosimilars offering cost-saving competition in the lucrative US biologic market, remains largely unfulfilled.

As on date, adoption of biosimilars has been hindered by lack of market access due to complex contracting dynamics, besides regulatory and legal uncertainty, and a general lack of clinical comfort with biosimilars.

Consequently, current state of biosimilar acceptance and access appear too insignificant. More so, as compared to traditional small molecule generic markets where their use is fueled by automatic substitution and payer formularies, over higher priced branded reference drugs.

It would not have been difficult, especially for the innovative biologic drug makers to brush this important study aside, had the US-FDA Commissioner – Scott Gottlieb would not have voiced what he did in March this year.

With this perspective, I shall discuss in this article, how access to biosimilar drugs are getting limited. In doing so, I shall begin with what the US-FDA Commissioner has recently highlighted in this area.

Yet another barrier:

As reported by Bloomberg on March 07, 2018, the US-FDA Commissioner Scott Gottlieb unambiguously expressed that biologic drug manufacturers enter into exclusive arrangements with Pharmacy Benefit Managers (PBMs) and insurers, who agree to cover only the old brands in return for rebates or discounts. This “rigged” payment scheme might quite literally scare the biosimilar competition out of the market altogether, he articulated, categorically.

US-FDA Commissioner delivered this speech at the National Health Policy Conference for America’s Health Insurance Plans. During this deliberation, Gottlieb criticized some unwanted and avoidable practices that stifle biosimilar development.

He observed, of the 9 approved biosimilars in the US, only 3 could be launched market. In many instances, patent litigation is the reason for such delay in launch, post FDA approval. Connecting the dots, the Commissioner observed, even after being in the market, biosimilars continue facing more uncertainty due to a ‘rigged payment scheme.’

Started with a great promise:

It is worth noting, till 2010 no regulatory pathway for marketing approval of biosimilars was in place in the world’s largest pharma market – the United States. Hence, despite biosimilar drugs being a treatment option in many countries over the last two decades, the first biosimilar was launched in the US, following this pathway, only in 2015. It was Zarxio ((Filgrastim-sndz) of Novartis – indicated for the treatment of patients with acute myeloid leukemia (AML).

Since then, US-FDA has approved nine biosimilars. Ironically biosimilar market size still remains small and much below the general expectations. Most biosimilar manufacturers are navigating through multiple tough hurdles for market launch of this relatively new genre of complex drugs.

Navigating through tough hurdles:

There are tough hurdles to navigate through, while launching biosimilars, especially in the US. Some of which are as follows:

Protracted litigations: The development and launch of most biosimilars get stuck in the multiple patent web-lock, created around original biologic molecules, leading to long drawn expensive litigations.

Pricing: Following small molecule generic drugs, most payers and consumers expect biosimilar pricing too will be no different. However, in practice, most biosimilars are priced just around 15 percent to 20 percent less than original biologics.

Interchangeability: Lack of interchangeability among presently approved biosimilars in the US limits payers’ and consumer choice for a shift from the reference biologic drugs to suitable biosimilars. This virtually restricts the use of biosimilars mostly to such drug-naïve patients.

Confidence: For various reasons, the confidence and familiarity of both physicians and the consumers on biosimilars remain suboptimal. Whether relatively cheaper biosimilars can be used in the same indications as the reference biologic to the new patients – as an alternative choice, is still not clear to many of them. This situation calls for increasing awareness programs involving all stakeholders.

Manufacturing: The manufacturing process of large molecule biosimilars is quite costly as compared to small molecule generic drugs. Hence, these are unlikely to follow a similar pricing pattern, attracting as high a discount as around 80 percent, compared to original branded drugs.

Some of these barriers I have discussed in my article, titled ‘Improving Patient Access To Biosimilar Drugs: Two Key Barriers’, published in this blog on July 31, 2017.

Conclusion:

Be that as it may, drug manufacturers continue to see tremendous opportunity in biosimilars. The interest is heating up, as about six of the top 10 biologic drugs are expected to go off-patent in the US by 2019.

Despite all this, it is generally believed, the prevailing situation will change even in the US. The regulator is expected to facilitate smoother market entry of biosimilars, facing much less obstacles on the way. As many strongly believe, these are possibly an outcome of intense industry lobbying, with the high-level policy makers.  Many of these hurdles can be removed by the regulators, themselves, including drug interchangeability.

The US-FDA Commissioner Scott Gottlieb has already said in a meeting on March 07, 2018, the FDA will start educating doctors and patients to minimize clinical and other concerns related to biosimilars. Therefore, going forward, greater competition in the biosimilar space is expected to increase the long-awaited price differential, as compared to reference biologic.

With greater support from the regulators, biosimilars still show a unique promise of greater acceptance and access to patients – occasionally ‘Rigged’ maneuvers by the vested interests notwithstanding.

R&D: Is Indian Pharma Moving Up the Value Chain?

Posted on by

It almost went unnoticed by many, when in the post product patent regime, Ranbaxy launched its first homegrown ‘New Drug’ of India, Synriam, on April 25, 2012, coinciding with the ‘World Malaria Day’. The drug is used in the treatment of plasmodium falciparum malaria affecting adult patients.  However, the company has also announced its plans to extend the benefits of Synriam to children in the malaria endemic zones of Asia and Africa.

The new drug is highly efficacious with a cure rate of over 95 percent offering advantages of “compliance and convenience” too. The full course of treatment is one tablet a day for three days costing less than US$ 2.0 to a patient.

Synriam was developed by Ranbaxy in collaboration with the Department of Science  and Technology of the Government of India. The project received support from the Indian Council of Medical Research (ICMR) and conforms to the recommendations of the World Health Organization (WHO). The R&D cost for this drug was reported to be around US$ 30 million. After its regulatory approval in India, Synriam is now being registered in many other countries of the world.

Close on the heels of the above launch, in June 2013 another pharmaceutical major of India, Zydus Cadilla announced that the company is ready for launch in India its first New Chemical Entity (NCE) for the treatment of diabetic dyslipidemia. The NCE called Lipaglyn has been discovered and developed in India and is getting ready for launch in the global markets too.

The key highlights of Lipaglyn are reportedly as follows:

  • The first Glitazar to be approved in the world.
  • The Drug Controller General of India (DCGI) has already approved the drug for launch in India.
  • Over 80% of all diabetic patients are estimated to be suffering from diabetic dyslipidemia. There are more than 350 million diabetics globally – so the people suffering from diabetic dyslipidemia could be around 300 million.

With 20 discovery research programs under various stages of clinical development, Zydus Cadilla reportedly invests over 7 percent of its turnover in R&D.  At the company’s state-of-the-art research facility, the Zydus Research Centre, over 400 research scientists are currently engaged in NCE research alone.

Prior to this in May 14, 2013, the Government of India’s Department of Biotechnology (DBT) and Indian vaccine company Bharat Biotech jointly announced positive results, having excellent safety and efficacy profile in Phase III clinical trials, of an indigenously developed rotavirus vaccine.

The vaccine name Rotavac is considered to be an important scientific breakthrough against rotavirus infections, the most severe and lethal cause of childhood diarrhea, responsible for approximately 100,000 deaths of small children in India each year.

Bharat Biotech has announced a price of US$ 1.00/dose for Rotavac. When approved by the Drug Controller General of India, Rotavac will be a more affordable alternative to the rotavirus vaccines currently available in the Indian market. 

It is indeed interesting to note, a number of local Indian companies have started investing in pharmaceutical R&D to move up the industry value chain and are making rapid strides in this direction.

Indian Pharma poised to move-up the value-chain:

Over the past decade or so, India has acquired capabilities and honed skills in several important areas of pharma R&D, like for example:

  • Cost effective process development
  • Custom synthesis
  • Physical and chemical characterization of molecules
  • Genomics
  • Bio-pharmaceutics
  • Toxicology studies
  • Execution of phase 2 and phase 3 studies

According to a paper titled, “The R&D Scenario in Indian Pharmaceutical Industry” published by Research and Information System for Developing Countries, over 50 NCEs/NMEs of the Indian Companies are currently at different stages of development, as follows:

Company Compounds Therapy Areas Status
Biocon 7 Oncology, Inflammation, Diabetes Pre-clinical, phase II, III
Wockhardt 2 Anti-infective Phase I, II
Piramal Healthcare 21 Oncology, Inflammation, Diabetes Lead selection, Pre-clinical, Phase I, II
Lupin 6 Migraine, TB, Psoriasis, Diabetes, Rheumatoid Arthritis Pre-clinical, Phase I, II, III
Torrent 1 Diabetic heart failure Phase I
Dr. Reddy’s Lab 6 Metabolic/Cardiovascular disorders, Psoriasis, migraine On going, Phase I, II
Glenmark 8 Metabolic/Cardiovascular /Respiratory/Inflammatory /Skin disorders, Anti-platelet, Adjunct to PCI/Acute Coronary Syndrome, Anti-diarrheal, Neuropathic Pain, Skin Disorders, Multiple Sclerosis, Ongoing, Pre-clinical, Phase I, II, III

R&D collaboration and partnership:

Some of these domestic companies are also entering into licensing agreements with the global players in the R&D space. Some examples are reportedly as follows:

  • Glenmark has inked licensing deals with Sanofi of France and Forest Laboratories of the United States to develop three of its own patented molecules.
  • Domestic drug major Biocon has signed an agreement with Bristol Myers Squibb (BMS) for new drug candidates.
  • Piramal Life Sciences too entered into two risk-reward sharing deals in 2007 with Merck and Eli Lilly, to enrich its research pipeline of drugs.
  • Jubilant Group partnered with Janssen Pharma of Belgium and AstraZeneca of the United Kingdom for pharma R&D in India, last year.

All these are just indicative collaborative R&D initiatives in the Indian pharmaceutical industry towards harnessing immense growth potential of this area for a win-win business outcome.

The critical mass:

An international study estimated that out of 10,000 molecules synthesized, only 20 reach the preclinical stage, 10 the clinical trials stage and ultimately only one gets regulatory approval for marketing. If one takes this estimate into consideration, the research pipeline of the Indian companies would require to have at least 20 molecules at the pre-clinical stage to be able to launch one innovative product in the market.

Though pharmaceutical R&D investments in India are increasing, still these are not good enough. The Annual Report for 2011-12 of the Department of Pharmaceuticals indicates that investments made by the domestic pharmaceutical companies in R&D registered an increase from 1.34 per cent of sales in 1995 to 4.5 percent in 2010. Similarly, the R&D expenditure for the MNCs in India has increased from 0.77 percent of their net sales in 1995 to 4.01 percent in 2010.

Thus, it is quite clear, both the domestic companies and the MNCs are not spending enough on R&D in India. As a result, at the individual company level, India is yet to garner the critical mass in this important area.

No major R&D investments in India by large MNCs:

According to a report, major foreign players with noteworthy commercial operations in India have spent either nothing or very small amount towards pharmaceutical R&D in the country. The report also mentions that Swiss multinational Novartis, which spent $ 9 billion on R&D in 2012 globally, does not do any R&D in India.

Analogue R&D strategy could throw greater challenges:

For adopting the analogue research strategy, by and large, the Indian pharma players appear to run the additional challenge of proving enhanced clinical efficacy over the known substance to pass the acid test of the Section 3(d) of the Patents Act of India.

Public sector R&D:

In addition to the private sector, research laboratories in the public sector under the Council for Scientific and Industrial Research (CSIR) like, Central Drug Research Institute (CDRI), Indian Institute of Chemical Technology (IICT) and National Chemical Laboratory (NCL) have also started contributing to the growth of the Indian pharmaceutical industry.

As McKinsey & company estimated, given adequate thrust, the R&D costs in India could be much lower, only 40 to 60 per cent of the costs incurred in the US. However, in reality R&D investments of the largest global pharma R&D spenders in India are still insignificant, although they have been expressing keenness for Foreign Direct Investments (FDI) mostly in the brownfield pharma sector.

Cost-arbitrage:

Based on available information, global pharma R&D spending is estimated to be over US$ 60 billion. Taking the cost arbitrage of India into account, the global R&D spend at Indian prices comes to around US$ 24 billion. To achieve even 5 percent of this total expenditure, India should have invested by now around US$ 1.2 billion on the pharmaceutical R&D alone. Unfortunately that has not been achieved just yet, as discussed above.

Areas of cost-arbitrage:

A survey done by the Boston Consulting Group (BCG) in 2011 with the senior executives from the American and European pharmaceutical companies, highlights the following areas of perceived R&D cost arbitrage in India:

Areas % Respondents
Low overall cost 73
Access to patient pool 70
Data management/Informatics 55
Infrastructure set up 52
Talent 48
Capabilities in new TA 15

That said, India should realize that the current cost arbitrage of the country is not sustainable on a longer-term basis. Thus, to ‘make hay while the sun shines’ and harness its competitive edge in this part of the world, the country should take proactive steps to attract both domestic as well as Foreign Direct Investments (FDI) in R&D with appropriate policy measures and fiscal incentives.

Simultaneously, aggressive capacity building initiatives in the R&D space, regulatory reforms based on the longer term need of the country and intensive scientific education and training would play critical role to establish India as an attractive global hub in this part of the world to discover and develop newer medicines for all.

Funding:

Accessing the world markets is the greatest opportunity in the entire process of globalization and the funds available abroad could play an important role to boost R&D in India. Inadequacy of funds in the Indian pharmaceutical R&D space is now one of the greatest concerns for the country.

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

  • Self-financing Research: This is based on:
  1. “CSIR Model”: Recover research costs through commercialization/ collaboration with industries to fund research projects.
  2. “Dr Reddy’s Lab / Glenmark Model”: Recover research costs by selling lead compounds without taking through to development.
  • Overseas Funding:  By way of joint R&D ventures with overseas collaborators, seeking grants from overseas health foundations, earnings from contract research as also from clinical development and transfer of aborted leads and collaborative projects on ‘Orphan Drugs’.
  • Venture Capital & Equity Market:  This could be both via ‘Private Venture Capital Funds’ and ‘Special Government Institutions’.  If regulations permit, foreign venture funds may also wish to participate in such initiatives. Venture Capital and Equity Financing could emerge as important sources of finance once track record is demonstrated and ‘early wins’ are recorded.
  • Fiscal & Non-Fiscal Support: Should also be valuable in early stages of R&D, for which a variety of schemes are possible as follows:
  1. Customs Duty Concessions: For Imports of specialized equipment, e.g. high throughput screening equipment, equipment for combinatorial chemistry, special analytical tools, specialized pilot plants, etc.
  2. Income tax concessions (weighted tax deductibility): For both in-house and sponsored research programs.
  3. Soft loans: For financing approved R&D projects from the Government financial institutions / banks.
  4. Tax holidays: Deferrals, loans on earnings from R&D.
  5. Government funding: Government grants though available, tend to be small and typically targeted to government institutions or research bodies. There is very little government support for private sector R&D as on date.

All these schemes need to be simple and hassle free and the eligibility criteria must be stringent to prevent any possible misuse.

Patent infrastructure:

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

  • Enhancement of patent literacy both in legal and scientific communities, who must be taught how to read, write and file a probe.
  • Making available appropriate ‘Search Engines’ to Indian scientists to facilitate worldwide patent searches.
  • Creating world class Indian Patent Offices (IPOs) where the examination skills and resources will need considerable enhancement.
  • ‘Advisory Services’ on patents to Indian scientists to help filing patents in other countries could play an important role.

Creating R&D ecosystem:

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

Universities to play a critical role:

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

‘Open Innovation’ Model:

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

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

Insignificant R&D investment in Asia-Pacific Region:

Available data indicate that 85 percent of the medicines produced by the global pharmaceutical industry originate from North America, Europe, Japan and some from Latin America and the developed nations hold 97 percent of the total pharmaceutical patents worldwide.

MedTRACK reveals that just 15 percent of all new drug development is taking place in Asia-Pacific region, including China, despite the largest global growth potential of the region.

This situation is not expected to change significantly in the near future for obvious reasons. The head start that the western world and Japan enjoy in this space of the global pharmaceutical industry would continue to benefit those countries for some more time.

Some points to ponder:

  • It is essential to have balanced laws and policies, offering equitable advantage for innovation to all stakeholders, including patients.
  • Trade policy is another important ingredient, any imbalance of which can either reinforce or retard R&D efforts.
  • Empirical evidence across the globe has demonstrated that a well-balanced patent regime would encourage the inflow of technology, stimulate R&D, benefit both the national and the global pharmaceutical sectors and most importantly improve the healthcare system, in the long run.
  • The Government, academia, scientific fraternity and the pharmaceutical Industry need to get engaged in various relevant Public Private Partnership (PPP) arrangements for R&D to ensure wider access to newer and better medicines in the country, providing much needed stimulus to the public health interest of the nation.

Conclusion:

R&D initiatives, though very important for most of the industries, are the lifeblood for the pharmaceutical sector, across the globe, to meet the unmet needs of the patients. Thus, quite rightly, the pharmaceutical Industry is considered to be the ‘lifeline’ for any nation in the battle against diseases of all types.

While the common man expects newer and better medicines at affordable prices, the pharmaceutical industry has to battle with burgeoning R&D costs, high risks and increasingly long period of time to take a drug from the ‘mind to market’, mainly due to stringent regulatory requirements. There is an urgent need to strike a right balance between the two.

In this context, it is indeed a proud moment for India, when with the launch of its home grown new products, Synriam of Ranbaxy and Lipaglyn of Zydus Cadilla or Rotavac Vaccine of Bharat Biotech translate a common man’s dream of affordable new medicines into reality and set examples for others to emulate.

Thus, just within seven years from the beginning of the new product patent regime in India, stories like Synriam, Lipaglyn, Rotavac or the R&D pipeline of over 50 NCEs/NMEs prompt resurfacing the key unavoidable query yet again:

Has Indian pharma started catching-up with the process of new drug discovery, after decades of hibernation, to move up the industry ‘Value Chain’?

Vaccines Development: Is it Just a Business Based on Fear?

Posted on by
Reply

‘Vaccination – A Business based on fear’, is the title of a book written by Dr. Gerhard Buchwald M.D, a German medical doctor and a vaccination critic. This book talks about:

“The damage and the deaths caused by vaccination are written off as ‘pure coincidence’, as something which would have occurred anyway, even without vaccination. Often damage is trivialized by claiming that vaccine damage occurs only very, very rarely, or the damage is covered up by naming as the cause, the most unlikely syndromes which can only be found in special literature.”

However, his critics and pro-vaccination experts do opine that this book “is a pathetic presentation of vaccination, from a self-proclaimed anti-vaccination lobbyist. It is full of half-truths, blatant lies and misrepresented statistics”.

Vaccination – one of the most important development in medicines: 

Quite in contrary to what Dr. Gerhard Buchwald wrote, vaccination was voted as one of the four most important developments in medicine of the past 150 years, alongside sanitation, antibiotics and anesthesia by readers of the ‘British Medical Journal’ in 2007. No wonder, Vaccines are one of the most successful and cost-effective public health interventions, which help preventing over 3 million deaths every year throughout the world topping the list in terms of lives saved.

Vaccines that are being developed and marketed today, though provide high level of protection against increasing number of diseases with reduction of associated morbidity and mortality, there is still a crying need for greater encouragement, more resource deployment and sharper focus towards newer vaccines development for many more dreaded and difficult diseases.

In tandem, concerted efforts need to be made by both the industry and the government to improve affordable access to all these vaccines for a larger section of the population, especially in the developing world.

Rejuvenating trend:

However, from the business perspective, the vaccine market, though initially considered to be a low-profit initiative, now has started being under rejuvenated focus keeping pace with improved understanding of the human immune system. The future scope of vaccines is immense, as the management of several potentially preventable diseases remains still unaddressed.

Consequently, the focus of the global vaccine industry is getting expanded from prophylactic vaccination for communicable disease (e.g. DTP vaccine) to therapeutic vaccines (e.g. Anti-cancer vaccines) and then possibly non-communicable disease vaccines (e.g. vaccines for coronary artery disease).

Shifting focus on vaccines types:

As per the ‘National Institute of Health (NIH)’ of USA, following are some types of vaccines that researchers usually work on:

  • Live, attenuated vaccines
  • Inactivated vaccines
  • Subunit vaccines
  • Toxoid vaccines
  • Conjugate vaccines
  • DNA vaccines
  • Recombinant vector vaccines

Among all these segments, sub-unit vaccine is the largest revenue generator, though synthetic vaccines, recombinant vector vaccines, and DNA vaccines are emerging as the fastest-growing segments.

The first vaccine of the world:

In 1796, Edward Anthony Jenner not only discovered the process of vaccination, alongside developed the first vaccine of the world for mankind – smallpox vaccine. To develop this vaccine Jenner acted upon the observation that milkmaids who caught the cowpox virus did not catch smallpox.

As per published data prior to his discovery the mortality rate for smallpox was as high as up to 35%. Thus, Jenner is very often referred to as the “Father of Immunology”, whose pioneering work has “saved more lives than the work of any other person.”

Later on in 1901 Emil Von Behring received the first Nobel Prize (ever) for discovering Diphtheria serum therapy.

R&D costs for vaccines:

According to a paper published by the US National Library of Medicine and National Institute of Health (NIH):

“A vaccine candidate entering pre-clinical development in 2011 would be expected to achieve licensure in 2022; all costs are reported in 2022 Canadian dollars (CAD). After applying a 9% cost of capital, the capitalized total R&D expenditure amounts to $ 474.88 million CAD.”

Issues and challenges:

To produce a safe and effective marketable vaccine, besides R&D costs, it takes reportedly around 12 to 15 years of painstaking research and development process.

Moreover, one will need to realize that the actual cost of vaccines will always go much beyond their R&D expenses. This is mainly because of dedicated and highly specialized manufacturing facilities required for mass-scale production of vaccines and then for the distribution of the same mostly using cold-chains.

Around 60% of the production costs for vaccines are fixed in nature (National Health Policy Forum. 25. January 2006:14). Thus such products will need to have a decent market size to be profitable.

Unlike many other medications for chronic ailments, which need to be taken for a long duration, vaccines are administered for a limited number of times, restricting their business potential.

Thus, the long lead time required for the ‘mind to market’ process for vaccine development together with high cost involved in their clinical trials/marketing approval process, special bulk/institutional purchase price and limited demand through retail outlets, restrict the research and development initiatives for vaccines, unlike many other pharmaceutical products.

Besides, even the newer vaccines will mostly be required for the diseases of the poor, like Malaria, Tuberculosis, HIV and ‘Non Communicable Diseases (NCDs)’ in the developing countries, which may not necessarily guarantee a decent return on investments for vaccines, unlike many other newer drugs. As a result, the key issue for developing a right type of newer vaccine will continue to be a matter of pure economics.

A great initiative called GAVI: 

Around 23 million children of the developing countries are still denied of important and life-saving vaccines, which otherwise come rather easily to the children of the developed nations of the world.

To resolve this inequity, in January 2000, the Global Alliance for Vaccines and Immunization (GAVI) was formed. This initiative was mainly aimed at generating sufficient fund to ensure availability of vaccines for children living in the 70 poorest countries of the world.

The GAVI Alliance has been instrumental in improving access to six common infant vaccines, including those for hepatitis B and yellow fever. GAVI is also working to introduce pneumococcal, rotavirus, human papilloma virus, meningococcal, rubella and typhoid vaccines in not too distant future.

In August 2013, GAVI has reportedly launched a campaign in Kenya to fight the world’s leading killer of children under five with a new Pneumococcal Vaccine for prevention from pneumonia, meningitis and sepsis, which kill more than half a million people a year.

GAVI hopes to avert 700,000 deaths by 2015 through the immunization of 90 million children with pneumococcal vaccines.

Global pharma majors Pfizer and GlaxoSmithKline (GSK) are producing the vaccines as a part of a deal part-funded by Britain, Italy, Canada, Russia, Norway and the Bill Melinda Gates Foundation.

Current trend in newer vaccine development:

Malaria Vaccine:

According to the National Institute of Health (NIH) of the United States, the results of an early-stage clinical trial published in August 8, 2013 in the ‘Journal Science’ for an investigational malaria vaccine has been found to be safe to generate an immune system response and to offer protection against malaria infection in healthy adults.

The scientists at Sanaria Inc., of Rockville, Md. Research Center developed this vaccine known as PfSPZ. The researchers reportedly found that injecting patients with live-but-weakened malaria causing parasites appeared to create a protective effect.

Earlier, Reuters on December 20, 2011 reported that the British scientists have developed an experimental malaria vaccine, which has the potential to neutralize all strains of the most deadly species of malaria parasite.

In October 2011, the data published for a large clinical trial conducted in Africa by GlaxoSmithKline on their experimental malaria vaccine revealed that the risk of children getting malaria had halved with this vaccine. Reuters also reported that other teams of researchers around the world are now working on different approaches to develop a malaria vaccine.

Tuberculosis vaccines:

The Lancet reported in March 2013, as BCG vaccination provides incomplete protection against tuberculosis in infants, a new vaccine, modified Vaccinia Ankara virus expressing antigen 85A (MVA85A), has been designed to enhance the protective efficacy of BCG. MVA85A was found well-tolerated and induced modest cell-mediated immune responses. However, the reasons for the absence of MVA85A efficacy against tuberculosis or M tuberculosis infection in infants would need exploration.

Universal Cancer vaccines:

In a breakthrough development, the Israeli company Vaxil BioTherapeutics has reportedly formulated a therapeutic cancer vaccine, now in clinical trials at Hadassah University Medical Center in Jerusalem.

If everything falls in place, the vaccine could be available about six years down the road, to administer on a regular basis not only to help treating cancer but also to keep the disease from recurring.

Though the vaccine is being tested against a type of blood cancer called multiple myeloma, if it works as the initial results indicate, its platform technology VaxHit could be applied to 90 percent of all known cancers, including prostate and breast cancer, solid and non-solid tumors.

HIV Vaccine:

A recent effort to find a vaccine for HIV is reportedly beginning in 2013 at laboratories in a London hospital and two centers in Africa. The work will be split equally between London, the Rwandan capital Kigali and Nairobi in Kenya.

It has been reported that scientists are recruiting 64 healthy adult volunteers for the trial, which is expected to take up to two years.

Vaccines requirements of the developing world: 

Developing countries of the world are now demanding more of those vaccines, which no longer feature in the immunization schedules of the developed nations. Thus to supply these vaccines at low cost will be a challenge, especially for the global vaccine manufacturers, unless the low margins get well compensated by high institutional demand.

India needs a vibrant vaccine business sector:

For greater focus on all important disease prevention initiatives, there is a need to build a vibrant vaccine business sector in India. To achieve this objective the government should create an enabling ecosystem for the vaccine manufacturers and the academics to work in unison. At the same time, the state funded vaccine R&D centers should be encouraged to concentrate more on the relevant vaccine development projects ensuring a decent return on their investments, for longer-term economic sustainability.

More often than not, these stakeholders find it difficult to deploy sufficient fund to take their vaccines projects successfully through various stages of clinical development in order to obtain marketing approval from the drug regulator, while registering a decent return on investments. This critical issue needs to be appropriately and urgently addressed by the Government to make the disease prevention initiatives in the country sustainable.

Changing market dynamics: 

Even in a couple of decades back, ‘Vaccines Market’ in India did not use to be considered as a focus area by many pharmaceutical companies. Commoditization of this market with low profit margin and unpredictable interest of the government/the doctors towards immunization were the main reasons. Large global players like Glaxo exited the vaccine market at that time by withdrawing products like, Tetanus Toxoid, Triple Antigen and other vaccines from the market.

Currently, the above scenario is fast changing. The vaccine market, as stated above, is getting rejuvenated not only with the National Immunization Program (NIP) of the country, but also with the emergence of newer domestic vaccines players and introduction of novel vaccines by the global players, which we shall discuss below.

In addition, the ‘Indian Academy of Pediatrics (IAP) Committee on Immunization’ now recommends the ‘best individual practices schedule’ for the children in consultation with their respective parents. Such schedule may not conform to NIP and include newer vaccines, broadening the scope of use of vaccines in general.

Global Market:

According to GBI Research Report, overall global vaccines market was valued at US$ 28 billion in 2010 and is expected to reach US$ 56.7 billion by 2017 with a CAGR of 11.5%. The key growth driver of this segment will be introduction of newer vaccines, which are currently either in the regulatory filing stage or in the late stages of clinical development.

The important international players in the vaccines market are GlaxoSmithKline, Sanofi, Pfizer, Novartis AG, Merck and SP-MSD. Together they represent around 88% of the total vaccine segment globally, the report highlights.

Indian Market:

McKinsey in its report titled, “India Pharma 2020: Propelling access and acceptance, realizing true potential“ stated that at 2% penetration, the vaccines market of India is significantly under-penetrated with an estimated turnover of around US$ 250 million, where the private segment accounts for two-thirds of the total. McKinsey expects the market to grow to US$ 1.7 billion by 2020.

India is one of largest markets for all types of vaccines in the world. The new generation and combination vaccines, like DPT with Hepatitis B, Hepatitis A and Injectable polio vaccine, are driving the growth. The demand for veterinary vaccines is also showing ascending trend. Pediatric vaccines contribute to around 60% of the total vaccines market in India.

Domestic Indian players like, Serum Institute, Shantha Biotecnics, Bharat Biotech and Panacea Biotech are poised to take greater strides in this direction. Bharat Biotech is incidentally the largest Hepatitis B vaccine producer in the world. Likewise, Serum Institute is reportedly one of the largest suppliers of vaccines to over 130 countries and claim that ’1 out of every 2 children immunized worldwide gets at least one vaccine produced by Serum Institute.’

The first new vaccine developed in India:

Indian scientists from Bharat Biotech Ltd in Hyderabad have reportedly developed a new oral vaccine against the Rotavirus induced diarrhea, where both vomiting and loose motion can severely dehydrate children very quickly. This is the first new vaccine developed in India, establishing itself as the first developing country to achieve this unique distinction.

Two recent vaccine JV and Partnership agreements in India:

British drug major GlaxoSmithKline (GSK) has reportedly agreed to form a 50-50 venture with the domestic Indian vaccine manufacturer Biological E Limited in January 2013 to develop a product that would combine GSK’s injectable polio shot with a vaccine produced by Biological E to protect against five diseases including diphtheria and tetanus.

In addition, MSD pharma of the United States and Indian drug major Lupin have announced a partnership agreement to market, promote and distribute, MSD’s 23-valent Pneumococcal Polysaccharide Vaccines under a different brand name in India for prevention of Pneumococcal disease, pneumonia being its most common form affecting adults.

A possible threat: 

As per reports most Indian vaccines manufacturers get a major chunk of their sales revenue from exports to UN agencies, charitable organizations like, the Bill & Melinda Gates Foundation and GAVI, and other country-specific immunization programs.

The report predicts, the virtual monopoly that Indian vaccines manufacturers have enjoyed in these areas, will now be challenged by China, as for the first time, in 2012, the Chinese national regulatory authority received World Health Organization’s (WHO) ‘pre-qualification’ certification that allows it to approve locally manufactured vaccines to compete for UN tenders. 

Action areas to drive growth:

McKinsey in its above report ‘India Pharma 2020’ indicated that the action in the following 4 areas by the vaccine players would drive the vaccine market growth in India:

  • Companies need to go for local production of vaccines or leverage supply partnerships. MSD and GlaxoSmithKline’s local partnership in India and for the HiB vaccine with Bio-manguinhos in Brazil may be cited as examples.
  • Companies will need to conduct studies on the economic impact of vaccination and establish vaccine safety and performance standards.
  • Extension of vaccine coverage beyond pediatricians and inclusion of general practitioners, consulting physicians and gynecologists will be essential.
  • Companies will need to enhance supply chain reliability and reduce costs.

Conclusion: 

On January 7, 2012, while requesting the ‘Overseas Indian Medical Professionals’ to partner with the institutions in India, the Health Minister, in his address, announced that the Ministry of Health has already introduced the second dose of measles vaccine and Hepatitis-B vaccination across the country. Moreover, from December 2011 a ‘Pentavalent Vaccine’ has been introduced, initially in 2 States, covering 1.5 million children of India.

All these augur quite well for the country. However, keeping in view of the humongous disease burden of India, immunization program with various types of vaccines should receive active encouragement from the government as disease prevention initiatives, keeping the future generation in mind.

If vaccine related pragmatic policy measures, with equal focus on their effective implementation, are initiated in the country, without delay, the domestic vaccine market, in turn, will receive much awaited further growth momentum. Such initiatives together with newer foreign players and modern imported vaccines coming in, would help the country addressing effectively a prime healthcare concern of the country in a holistic way.

It is about time to aggressively garner adequate resources to develop more modern vaccines in the country, promote and implement vaccine awareness campaigns in the nation’s endeavor for disease prevention before they strike hard and at times fatally.

That said, taking available real world facts into account, doesn’t Dr. Gerhard Buchwald’s and today’s anti-vaccination lobbyists’ postulation, ‘Vaccination – A Business based on fear’, appear to be emanating from a self created world of doom and gloom, defying public health interest for effective disease prevention?

Small Steps, yet Giant Leaps: In Pursuit of Affordable Medicines for All

Posted on by
Reply

Since last few years, some small yet very significant steps are being taken, mostly by the respective Governments, in and outside India, to provide affordable healthcare in general and affordable medicines in particular, for all.

It is well recognized that drug prices play as critical a role as a robust healthcare infrastructure and quality of its delivery system to provide affordable healthcare to the general population of any country. Thus, it is not a ‘chicken and egg’ situation. All these issues must be addressed simultaneously and with equally great care.

A WHO report:

A World Health Organization (WHO) titled, “Improving access to medicines through equitable financing and affordable prices” highlights as follows:

“In many countries medicines account for over half of total health expenditures and are often unavailable and unaffordable to consumers who need them. Up to 90% of the population in developing countries still buys medicines through out-of-pocket payments, and are often exposed to the risk of catastrophic expenditure.”

Definition of ‘Access to Medicines’:

How then one will define ‘access to medicines’?

United Nations Development Group, in a paper titled ‘Indicators for Monitoring the Millennium Development Goals (United Nations, New York, 2003) defined  ‘Access to Medicines’ as follows:

‘Having medicines continuously available and affordable at public or private health facilities or medicine outlets that are within one hour’s walk from the homes of the population.’

Healthcare ‘affordability’ is critical:

Despite healthcare infrastructure in India being inadequate with a slow pace of development, affordability of healthcare, including medicines, still remains critical. 

This is mainly because, even if a quality healthcare infrastructure together with an efficient delivery system is put in place without ensuring their affordability, patients’ access to quality healthcare products and services will not improve, especially in India, where private healthcare dominates.

Diversionary measures should not cause distraction:

Although, maximum possible resources must be garnered to address the critical issue of expanding quality healthcare infrastructure and delivery system sooner, the focus of the government, as stated above, must not get diverted from making healthcare products and services affordable to patients, at any cost.

This should continue despite diversionary measures from some quarter to deflect the focus of all concerned from affordability of healthcare to lack of adequate healthcare infrastructure and its delivery mechanisms in India.

This, in no way, is an ‘either/or’ situation. India needs to resolve both the issues in a holistic way, sooner.

Small Steps:

In an earnest endeavor to provide affordable medicines to all, the following small and simple, yet significant steps have been taken in and outside India:

  1. Strong encouragement for generic drugs prescriptions
  2. Regulatory directive for prescriptions in generic names
  3. In case that does not work – Government initiative on Patient Empowerment

In this article, I shall try to capture all these three small steps.

1. Strong encouragement for generic drugs prescriptions:

A. Generic drugs improve access and reduce healthcare cost:

A Special Report From the ‘US-FDA Consumer Magazine’ and the FDA Center for Drug Evaluation and Research, Fourth Edition / January 2006 states that generic drugs offer significant savings to the consumers.

Quoting a 2002 study by the Schneider Institute for Health Policy at Brandeis University in Waltham, Mass., it reiterated that if Medicare increased the rate of generic usage to that of similar high-performing private sector health plans, its 40 million beneficiaries could see potential savings of US$14 billion.

Another US-FDA report titled, ‘Greater Access to Generic Drugs’ also reinforced the argument that rising costs of prescription drugs remain a major challenge for consumers, especially older Americans. To address this issue effectively generics can play a critical role by providing less expensive medications.

B. ‘Obamacare’ followed this direction resulting decline in spend on high priced Patented Drugs:

Recently The New York Times quoting IMS Health reported that nationwide turnover of patented drugs in the U.S actually dropped in 2012. This decline though was just by 1 percent to US$ 325 billion, is indeed very significant and happened due to increasing prescription trend for low cost generics across America since past several years.

It is interesting to note this trend in America where the cost of medicines account for just about 15 percent (against over 70 percent in India) of the nation’s health care expenditures.

IMS Health reported that in 2012, 84 percent of all prescriptions were dispensed as generics and estimated use of generics may reach even as high as 86 to 87 percent in the U.S.

However, many experts believe that this trend is a result of many blockbusters like Lipitor going off patent during this period and no major breakthrough medicines coming with perceptible added value in these large therapy areas.

That said, lesser number of small molecule blockbuster drugs is set to lose patent protection over the next several years and the complexity in manufacturing and getting marketing approvals of large molecule biosimilar drugs in the U.S could arrest this trend.

Biosimilar drugs though are available in European Union, are expected to be available in the America not before at least two more years.

Despite a sharp increase in prescriptions for generic drugs, some of the patented medicines came with ‘jaw-dropping’ price tags: four drugs approved in 2012 carry a yearly cost of more than US$ 200,000 per patient, though the cost of development of some of these drugs do not exceed US$ 250 million, as reported by Forbes.

2. Regulatory directive for prescriptions in generic names:

A. Different situation in India:

Although increasing trend of generic prescriptions is bringing down the overall cost of healthcare in general and for medicines in particular elsewhere in the world, the situation is quite different in India.

In India over 99 percent of over US$ 13 billion domestic pharmaceutical market constitutes predominantly of branded generics and some generic medicines without brand names.

B. Allegation of branded generic prescriptions linked with marketing malpractices:

As Reuters reported, quoting public health experts and some Indian doctors, that due to an unholy nexus between some pharmaceutical companies and a large section of the medical profession, drugs are not only dangerously overprescribed, but mostly expensive branded generics are prescribed to patients, instead of cheaper equivalents. The reports said that this situation can be ‘devastating for patients — physically and financially — in a country where health care is mostly private, out of pocket, unsubsidized and 400 million people live on less than US$ 1.25 a day’.

It is now a matter of raging debate that many branded generic prescriptions are closely linked with marketing malpractices.

Not just the media and for that matter even a Parliamentary Standing Committee in one of its reports highlighted, bribing doctors by many pharma players in various forms and garbs to prescribe their respective brand of generic drugs has now reached an alarming proportion in India, jeopardizing patients’ interest seriously, more than ever before and  observed that speedy remedial measures are of utmost importance.

C. MCI initiative on prescription in generic names: 

To address this major issue the Medical Council of India (MCI) in its circular dated January 21, 2013 addressed to the Dean/Principals of all the Medical Colleges, 
Director of all the hospitals and the
 Presidents of all the State Medical Councils directed as follows:

“The Indian Medical Council (Professional Conduct, Etiquette and Ethics) Regulations, 2002 inter-alia prescribes as under regarding use of generic names of drugs vide clause 1.5.

1.5 – Use of Generic names of drugs: Every physician should, as far as possible, prescribe drugs with generic names and he/she shall ensure that there is a rational prescription and use of drugs.”

All the Registered Medical Practitioners under the IMC Act are directed to comply with the aforesaid provisions of the Regulations without fail.

You are requested to give wide publicity of the above regulation to ensure that all the doctors practicing medicine under your jurisdiction comply with the regulation.”

MCI also urged the Medical profession to implement the above provision for prescriptions in generic names both in its letter and spirit.

As the situation has not changed much just yet, it is up to the MCI now to enforce this regulation exactly the way as it has intended to. Otherwise the value of this circular will not even be worth the paper on which it was printed by this august regulatory body.

D. Parliamentary Standing Committee recommends it:

As mentioned above, prior to this circular, Parliamentary Standing Committee (PSC) for Health and Family Welfare in its recommendation to the ‘Rajya Sabha’ of the Indian Parliament on August 4, 2010, also recommended prescription of medicines by their generic names.

E. Why is the bogey of ‘product quality’ so active only for generic prescriptions and not for branded generics?

It is indeed difficult to fathom why is the product quality issue, which could make drugs unsafe for the patients, being raised so much for generic medicines without a brand name and not for branded generics?

The following questions should well be raised for greater clarity on the quality issue with generic medicines without a brand name, for all concerned:

  • Are all generic medicines of dubious quality and branded generics are of good quality?
  • If quality parameters can be doubted for both branded generics and generics without a brand name, in many cases, why then raise this issue only in context of prescribing generic medicines ?
  • If quality issues are not much with the larger companies and are restricted to only smaller companies, why then some branded generic drugs of smaller companies are being prescribed so much by the doctors?
  • Currently many large companies market the same drugs both as generics without a brand name and also as branded generics, why then the branded generic versions are prescribed more than their generic equivalents, though manufactured by the same large companies having the same quality profile?
  • Why are the generic medicines of good quality available at ‘Jan Aushadhi’ outlets (though small in number) cost a fraction of their branded generic equivalents and not being prescribed by most of the doctors?
  • Why do the doctors not show much interest in prescribing generic medicines as of date and defend the branded generics on the same ‘quality’ platform?
  • Why not those who argue that phonetically similar or wrong reading of generic names at the chemist outlets may cause health safety hazard to the patients, also realize that many already existing phonetically similar brand names in totally different therapy areas may cause similar hazards too?
  • How does a doctor while prescribing a branded generic or generic medicine pre-judge which ones are of good quality and which others are not?

These questions, though may be uncomfortable to many, nevertheless merit clear, unambiguous, straight and specific answers.

3. In case MCI directive does not work – Government initiative on ‘Patient Empowerment’:

A. Laudable Government initiative:

Recognizing this issue in tandem, on December 7, 2012 the Department of Pharmaceuticals together with the National Pharmaceutical Pricing Authority announced as follows:

“There are number of drugs available in the market with same medicament composition with wide variation in their prices.  The prescription of doctors also varies from low price to high priced drugs for the same ailment. Government of India intends to launch an SMS based patient awareness scheme, which would enable the patients to know the cheaper alternatives medicines available”.

The timeline for implementation of this initiative was announced as six month from the date of awarding the contract.

It was reported that in this mobile phone based program, consumers by sending a text message of any branded generic drug prescribed by the doctors would get an SMS reply with a list of brands of the same molecule along with their prices to exercise their choice of purchase.

As usually happens with most government decisions, the gestation period of this laudable ‘patient empowerment’ initiative perhaps will get over not before end 2013.

B. One interesting private initiative:

One interesting private websites that I have recently come across offering information on branded generic drugs is www.mydawaai.com (I have quoted this website just to cite an example and not to recommend or promote it in any form or manner). There may be other such websites, as well, in the cyberspace.

However, in this website, if anyone types the brand name of the drug that one is looking for, the following details will be available:

  1. The generic version of branded medicine.
  2. The company manufacturing the brand.
  3. Its estimated cost in India
  4. Alternative brand names with same generic salt.
  5. The cost effectiveness for different brand for the same salt.

Such information, if available easily from the Government or any highly credible source, will indeed help patients having access to affordable low cost medicines to lessen their out of pocket financial burden, at least for medicines.

Conclusion:

In India, even if branded generic prescriptions continue despite MCI directive, to empower patients making an informed choice to buy low priced formulations of the same prescribed molecule, the above ‘Patient Empowerment’ initiative will play a very critical role.

Thus, I reckon, to improve access to affordable medicines in India, like many other countries elsewhere in the world, the above small steps that are being taken by the MCI, the Department of Pharmaceuticals, the National Pharmaceutical Pricing Authority and other private players are indeed laudable and must be encouraged.

Kudos will pour in, from India and abroad, if such small and simple steps get ultimately translated into a giant leap in the healthcare space of the country…for patients’ sake.

Takes ‘Two to Tango’: Encashing Opportunities with Biologic drugs in India

Posted on by
Reply

Despite current ‘Patent Cliff’ ongoing research on biologics is now at the forefront of the Global Pharmaceutical Industry.  The bottom-line impact of a successful new biologic molecule to treat intractable ailments like, cancer, blood disorders, Parkinson’s, Myasthenia Gravis, Multiple Sclerosis, Alzheimer’s diseases, will be huge.

Currently, faster growth of this segment as compared to conventional small molecules is primarily driven by novel technologies and highly targeted approaches, the final outcome of which is being more widely accepted by both physicians and patients.

Lesser generic competition makes it more attractive:

After patent expiry, innovators’ small molecule brands become extremely vulnerable to cut throat generic competition with as much as 90% price erosion.This is mainly because  these small molecules are relatively easy to replicate by many generic manufacturers and the process of getting their regulatory approval is also not as stringent as biosimilar drugs in most of the markets of the world.

On the other hand biologic drugs involve difficult, complex and expensive processes for development. Such resource intensive scientific expertise together with stringent regulatory requirements for obtaining marketing approval, especially in the developed markets of the world like, EU and USA, help creating a significant market entry barrier for many players. That is why even after patent expiry, biologics enjoy significant brand protection from generic competition for quite some time, in many cases.

It is for this reason brands like the following ones are expected to go relatively strong even for some more time, without any significant competition from biosimilar drugs in many of the major markets of the world:

Brand Company Launch date
Rituxan Roche/Biogen idec 1997
Herceptin Roche 1998
Remicade Centocor/J&J 1998
Enbrel Amgen/Pfizer 1998

Global Market:

In 2011 the turnover of Biologic drugs increased to over US$ 175 billion in the total market of US$ 847 billion. The sale of Biosimilar drugs outside USA exceeded US$ 1 billion.

Six biologic drugs featured in the top 10 best selling global brands in 2012 with Humira of AbbVie emerging as the highest-selling biologics during the year.  Roche remained the top company by sales for biologics with anticancer and monoclonal antibodies.

According to IMS Health, by 2015, sales of biosimilars are expected to reach between US$ 1.9 – 2.6 billion, an increase from US$ 378 million for the year to the first half of 2011.

Attractiveness:

The answer to the key question of why do so many companies want to enter into the biotech space of the business, in summary, could lie in the following:

  • Truly innovative small molecule discovery is becoming more and more challenging and expensive with the low hanging fruits already being plucked.
  • More predictable therapeutic activity of biologics with better safety profile.
  • Higher percentage of biologics have turned into blockbuster drugs in the recent past.
  • Market entry barrier for biosimilar drugs, after patent expiry of the original molecule, is much tougher than small molecule generics.
  • A diverse portfolio of both small and large molecules will reduce future business risks.

A 2012 report by PwC titled ‘From Vision to Decision: Pharma 2020’ states that “the next few years may look bleak for pharma, but we’re convinced that the following decade will bring a golden era of renewed productivity and prosperity.”

The document also points out that the global pharmaceutical industry is now focusing its R&D initiatives on biologics for the treatment of cancer and rare diseases. Nearly 30 percent of the 7,891 molecules currently in clinical testing cover cancer and autoimmune conditions.

Another emerging opportunity:

As stated above, unlike commonly used ‘small molecule’ drugs, ‘large molecule’ biologics are developed from living cells using very complex processes.

It is virtually impossible to replicate these protein substances, unlike the ‘small molecule’ drugs. One can at best develop a biologically similar molecule with the application of high degree of biotechnological expertise. These drugs are known as ‘Biosimilar Drugs’ and usually cost much less than the original ones.

Biosimilar drugs market is currently fast evolving across the world with varying degree of pace and stages of developments. The U.S currently holds the leadership status in the production of biologics, with around 45 percent of the total share. India’s share, now being at 7 percent is continuously increasing.

Future business potential with cost arbitrage of India:

In 2013, products like, Avonex of Biogen Idec, Humalog of Eli Lilly, Rebif of Merck KgaA, Nupugen of Amgen will go off-patent, paving the way of entry for lower priced biosimilar drugs. The sum total of revenue from all such drugs comes to over U.S$ 15 billion.

The report from the ‘Business Wire’ highlights that, ‘the manufacture and development of a biosimilar molecule requires an investment of about US$ 10 to 20 million in India, as compared to US$ 50 to 100 million in developed countries’, vindicates the emergence of another lucrative business opportunity for India for such drugs with significant cost arbitrage.

Government support in India:

In India, the government seems to have recognized that research on biotechnology has a vast commercial potential for products in human health, including biosimilars, diagnostics and immunobiologicals, among many others.

To give a fillip to the Biotech Industry in India the National Biotechnology Board was set up by the Government under the Ministry of Science and Technology way back in 1982. The Department of Biotechnology (DBT) came into existence in 1986. The DBT currently spends around US$ 300 million annually to develop biotech resources in the country and has been reportedly making reasonably good progress.

The DBT together with the Drug Controller General of India (DCGI) has now prepared ‘Regulatory Guidelines for Biosimilar Drugs’ in conformance to international quality and patient safety standards.

Currently, a number of both financial and non-financial incentives have been announced by the Central and the State Governments to encourage growth of the biotech industry in India, which include tax incentives, exemption from VAT and other fees, grants for biotech start-ups, financial assistance with patents, subsidies on investment from land to utilities and infrastructural support with the development of ten biotech parks through ‘Biotechnology Parks Society of India’.

A commendable DBT initiative:

Towards this direction, the Department of Biotechnology (DBT) of the Government of India has taken a commendable step to encourage the small and medium scale business outfits by setting-up ‘The Small Business Innovation Research Initiative (SBIRI)’. This scheme has been launched to boost ‘Public-Private-Partnership (PPP)’ projects in the country.

SBIRI supports ‘the high-risk pre-proof-of-concept research’ and ‘late stage development’ in small and medium size companies to get them involved in the development of biologics.

Some examples:

Examples of some among many of the PPP initiatives in the healthcare space under SBIRI are as follows:

Besides, Indian pharmaceutical majors like Dr. Reddy’s Laboratories (DRL), Reliance Life Science, Shantha Biotech, Ranbaxy, Biocon, Wockhardt and Glenmark have made good investments in biotech drugs manufacturing facilities keeping an eye on the emerging opportunities with Biosimilar drugs in the developed markets of the world.

Funding remains a critical issue:

That said, many industry experts do feel that R&D funding for the Biotech sector in the country is grossly inadequate. Currently, there are not many ‘Venture Capital’ funds for this sector and ‘Angel Investments’ almost being non-existent, Indian biotech companies are, by and large, dependent on Government funding.

Making India a global hub for biosimilar manufacturing:

However, with around 40 percent cost arbitrage, adequate government support and without compromising on the required stringent international regulatory standards, the domestic ‘biologic’ players should be able to establish India as one of the most preferred manufacturing destinations to meet the global requirements for particularly ‘biosimilar drugs’.

Experience in conforming to stringent US FDA manufacturing standards, having largest number of US FDA approved plants outside USA, India has already acquired a clear advantage in manufacturing high technology chemical based pharmaceutical products in India. Significant improvement in conformance to Good Clinical Practices (GCP) standards will offer additional advantages.

Conclusion:

With increasing support from the government and fueled by creative, scientific and technological inputs from various experts and entrepreneurs in the country, India has the potential to emerge as one of Asia’s best powerhouses in the field of biosimilars drugs by the end of this decade. It will take ‘two to tango’.
