The Department Related Parliamentary Committee on Health and Family Welfare presented its 59th Report of 118 pages in total on the functioning of the Indian Drug Regulator – the Central Drug Standards Control Organization (CDSCO) in both the houses of the Parliament on May 08, 2012.

Regulations and the Regulator for the Pharmaceutical Industry of India – A snapshot:

The pharmaceutical industry in India is regulated, broadly, in the following ways:

  • Drugs and Cosmetics Act of India 1940 together with Drugs and Cosmetics Rules regulate the Pharmaceutical Industry across the country for all types of drugs, irrespective of the fact whether these are locally produced or imported from other countries of the world.
  • The office of the Drug Controller General of India (DCGI) is primarily responsible for effective enforcement of most of these laws and rules across the country.
  • All issues related to clinical trials, product approval and standards, import licenses and introduction of new drugs are the direct responsibilities of the DCGI’s office.
  • Health being a state subject in India, on the ground, Foods and Drugs Administrations (FDA) of the State Governments enforce laws related to approvals for setting up pharmaceutical production facilities and obtaining licenses to stock and sell drugs in their respective states.
  • A valid license from the Drug Regulator is necessary for location-wise manufacturing of each type of drugs in the country with a mandatory requirement of periodic renewal of such licenses, as specified therein.

A key point to ponder from the Report:

The report begins with the following observations:

Medicines apart from their critical role in alleviating human suffering and saving lives have very sensitive and typical dimensions for a variety of reasons. They are the only commodity for which the consumers have neither a role to play nor are they able to make any informed choices except to buy and consume whatever is prescribed or dispensed to them because of the following reasons:

  • Drug regulators decide which medicines can be marketed
  • Pharmaceutical companies either produce or import drugs that they can profitably sell
  • Doctors decide which drugs and brands to prescribe
  • Consumers are totally dependent on and at the mercy of external entities to protect their interests.

In this prevailing condition, the committee felt that effective and transparent drug regulation, free from all commercial influences, is absolutely essential to ensure safety, efficacy and quality of drugs keeping just one objective in mind, i.e., welfare of patients.

Quite in congruence with this critical requirement the Committee examined in detail the functioning of CDSCO, which includes the office of the DCGI, as well, to ascertain whether applicable rules and laws are being implemented efficiently and honestly for the best interest of patients by the Drug Regulator of India.

Why is the ‘Mission Statement’ of CDSCO industry oriented and not patient focused?

Very interestingly, the report highlights with the following examples, how out of line the ‘Mission Statement’ of CDSCO is as compared to the same of other countries by being blatantly industry oriented instead of safeguarding Public Health and safety:

Drug Regulator

The ‘Mission Statement’
1

CDSCO, India

 Meeting the aspirations…. demands and requirements of the pharmaceutical industry.
2.

USFDA, USA

 Protecting the public health by assuring the safety, efficacy, and security of human and veterinary drugs.
3.

MHRA, UK

 To enhance and safeguard the health of the public by ensuring that medicines and medical devices work, and are acceptably safe.
4.

TGA, Australia

 Safeguarding public health & safety in Australia by regulatingMedicines…

Consequently, the Committee took a very strong exception for such utter disregard and continued neglect of patients’ interest by the Drug Regulator of India and recommended immediate amendment of the ‘Mission Statement’ of CDSCO incorporating in very clear terms that the existence of the organization is solely for the purpose of protecting the best interest of patients and their safety. It is needless to say that thereafter, it will require stringent conformance with the same with high precision.

Some very critical findings:

The committee in its report made the following critical findings, besides others:

  • “A total of 31 new drugs were approved in the period January 2008 to October 2010 without conducting clinical trials on Indian patients.
  • Thirteen drugs scrutinized by the panel are not allowed to be sold in the United States, Canada, Britain, European Union and Australia.
  • Sufficient evidence is available on record to conclude that there is collusive nexus between drug manufacturers, some functionaries of CDSCO and some medical experts.
  • When it comes to approving new drugs, too much is left to the absolute discretion of the CDSCO officials.
  • The Central Government can either issue directions under Section 33P to states to withdraw the licenses of FDCs granted without prior DCGI approval or the Central Government can itself ban such FDCs under Section 26A.
  • Though the Ministry is forming Drug Approval Committees, which are given very important powers, there is no transparent procedure for the selection of experts of such Committees.
  • Accurate information on drugs for patients is absolutely essential to prevent inappropriate use more particularly in children, elderly, during pregnancy and lactation.
  • Due to the sensitive nature of clinical trials in which foreign companies are involved in a big way and a wide spectrum of ethical issues and legal angles, different aspects of Clinical trials need a thorough and in-depth review.”

The Report named some pharmaceutical companies:

While arriving at these points, the report indicted some pharmaceutical companies, both national and international as follows (in alphabetical order):

Company Company Company
1. Bayer 8. Lundbeck 15. Ranbaxy
2. Cipla 9. Macleods 16. Sanofi
3. Centaur 10. Mars 17. Sun Pharmaceuticals
4. Emcure 11. Merck 18. Themis
5. Eli Lilly 12. Novartis 19. Theon
6. GlaxoSmithKline 13. Pharmacia (acquired by Pfizer) 20. UCB
7. Hetero 14. Phamasset Inc. (a subsidiary of Gilead) 21. Venus

A scathing remark against CDSCO:

The report made the following scathing remarks on CDSCO in its point 2.2:

“The Committee is of the firm opinion that most of the ills besetting the system of drugs regulation in India are mainly due to the skewed priorities and perceptions of CDSCO. For decades together it has been according primacy to the propagation and facilitation of the drugs industry, due to which, unfortunately, the interest of the biggest stakeholder i.e. the consumer has never been ensured.”

Allegation of possible collusion needs to be thoroughly probed:

The report also deliberates not only on the utter systemic failure of CDSCO along with the DCGI’s office to enforce law effectively, but also towards a possible collusion between CDSCO and the pharmaceutical industry to implement a self-serving agenda by hoodwinking the system. This is a very serious allegation, which needs to be thoroughly probed and the findings of which should be made public for everybody’s satisfaction.

Parliamentary Committee Report is a ‘considered advice and of persuasive value’:

Though any report of such Parliamentary Committee has been stated to have a persuasive value and be treated as considered advice given by the Committee, which in this case is to CDSCO, DCGI, Ministry of Health and also the industry.

Some probes already initiated:

Reuters in its publication of May 9, 2012 indicated that this Parliamentary Committee Report has prompted greater scrutiny even from the US regulators, which are reportedly investigating a number of drug companies under the Foreign Corrupt Practices Act (FCPA).

Initial reports also indicate that both the Indian Government and some large international pharmaceutical companies have announced detail probe based on this report at their respective ends.

Some remedial measures - Mashelkar Committee Recommendations:

Considering all these, besides taking appropriate remedial measures related to Clinical Trials of drugs in India, it is about time to reconsider the recommendations of Dr. R. A. Mashelkar Committee on the subject and make amendments in the Act accordingly to facilitate creation of a ‘Central Drugs Authority (CDA)’ introducing, along with other measures, a centralized licensing system for the manufacture, sale, export and distribution of drugs.

Why does India need CDA?

I firmly believe that the formation of the ‘Central Drugs Authority (CDA)’ will provide the following significant benefits to the Industry and also to the Government for the best interest of public health and safety:

  1. Achieving uniform interpretation of the provisions of the Drugs & Cosmetics Act & Rules
  2. Standardizing procedures and systems for drug control across the country
  3. Enabling coordinated nationwide action against spurious and substandard drugs
  4. Upholding uniform quality standards with respect to exports to foreign countries from anywhere in India
  5. Implementing uniform enforcement action in case of banned and irrational drugs
  6. Creating a pan-Indian approach to drug control and administration
  7. Evolving a single-window system for pharmaceutical manufacturing and research undertaken anywhere in the country.

Conclusion:

As a consequence of the above report of the Parliamentary Committee identifying gross irregularities in the functioning of the CDSCO, the Minister of Health and Family Welfare (MoHFW) of India Mr. Ghulam Nabi Azad has already announced constitution of a three-member committee to probe into the matter in depth.

Following well-known experts have been named as members of this high powered committee, which will submit its report and recommendations in two months’ time:

  • Dr. V.M. Katoch: Director General, Indian Council of Medical Research (ICMR),
  • Dr. P.N. Tandon: President, National Brain Research Centre
  • Dr. S.S. Aggarwal: Former Director, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow

The committee has been mandated to:

  • Examine the validity of the scientific and statutory basis adopted for approval of new drugs without clinical trials
  • Outline appropriate measures to bring about systemic improvements in the processing and grant of statutory approvals
  • Suggest steps to institutionalize improvements in other procedural aspects of functioning of the CDSCO

The outcome of the report of this high powered committee, internal probes voluntarily initiated by some pharmaceutical companies and possible implementation of the ‘Mashelkar Committee’ recommendations on the formation of CDA in the country will hopefully bring in some systemic changes in the drug regulatory system of India, for patients’ sake.

Patients’ Safety, regulatory approval of Biosimilar Drugs in India and WHO Biosimilar guidelines

Posted on by

Biopharmaceutical drugs are broadly defined as:

”Those medicines produced using a living system or genetically modified organism. These drugs are different from traditional chemical medicines in many ways. Size of the molecule is one of the most obvious distinctions: the molecules of a biopharmaceutical medicine are much larger, have far more complex spatial structures and are much more diverse (“heterogeneous”) than the chemical molecules which make up classical drugs.”

The Biosimilar drugs:

Biosimilar drugs are follow-on versions of original biopharmaceutical medicines. Biosimilar medicines are intended to have the same mechanism of action for the same diseases as the original biopharmaceutical drugs.

The term “bio generic” will be misleading for off patent biopharmaceutical products, as no two biopharmaceutical products could possibly be exactly identical. This is mainly because of the following reason:

“Whereas generics of chemistry based medicines are identical in the molecular structure and therefore copies of the original product, based on a strict definition of “sameness”, a corresponding definition cannot be established for biosimilar medicines because of their nature and the complexity of their manufacturing process. Here post-translational modifications are dependent of the host cell and the process.”

Thus the common terminologies used to describe such products when the original products go off-patent are follow-on biologics and biosimilars.

Manufacturing Conditions of biosimilars ultimately define the final product:

Unlike chemical drugs, the manufacturing conditions and the process followed to produce biopharmaceutical drugs largely define the final product and its quality. Any alteration to the manufacturing process may result in a completely different product. Additionally proteins are relatively unstable. Thus additional measures in their storage, formulation and delivery are very critical.

Key concerns with the existing regulatory approval process for Biosimilar drugs:

• Small changes in the manufacturing process of biosimilar drugs could significantly affect the safety and efficacy of the molecule.

• Due to the very nature of a biologic it is virtually impossible for two different manufacturers to manufacture two identical biopharmaceutical drugs. Identical host expression systems, processes and equivalent technologies need to be demonstrated in extensive comparability trials. Thus, as stated above, a ‘bio generic’ cannot exist.

• As against the situation applicable for generics of chemical molecules which can be replicated, biosimilar drugs cannot be replicated. At the most such biopharmaceuticals can be at the most “similar” but not “identical” to the original reference products. To ensure desired efficacy and safety of biosimilar products, these products should only be approved after charting out a formal and well validated regulatory pathway for the biosimilar drugs in India.

• Currently biosimilar drugs are given marketing approval by the regulator without such guidelines for large molecule biological and following just the bioequivalence model as specified in the Schedule Y of the Drugs and Cosmetics Act (D&CA) of India for small molecule chemical entities only, as the current Drugs and cosmetics Acts of India, very unfortunately, do not differentiate between large and small molecular drugs. This could, in turn, endanger patients’ safety with serious medical consequences.

Although, Central Drugs Standard Control Organization (CDSCO) and the Drugs Controller General of India (DCGI) are responsible for approvals of the new drug applications, health being a state subject, respective state regulatory authorities are responsible for granting manufacturing license to the pharmaceutical manufacturers.

Pharmaceutical manufacturers setting up facilities in the states, where regulatory oversight and incidences of weaker enforcement are common, will be able to market their products, including biosimilars, across the country. It is alleged that there are hardly any regulatory control over the mistakes or offences committed by the State Drug authorities who permit manufacture of drugs even unapproved by the DCGI. The existing issue of mushrooming of various irrational Fixed Dose Combinations (FDC) products in India will vindicate this point.

The Government’s response to this public health concern:

Express Pharma in its June 30, 2009 edition reported Dr M K Bhan, Secretary, Government of India, DBT, saying, “The first question is do we have written guidelines available to people? Currently, we have a large committee of about 30 people in the Review Committee on Genetic Manipulation (RCGM) which frequently discusses the current FDA and EMEA guidelines and makes sure that it is updated as per the guidelines in case by case approvals.”

He acknowledged, to make sure that the product is identical or original is harder for biological than for chemical entities and said, “So the next question is, what is the degree of difficulty you create to be sure that some of the products in the in vitro laboratories and the strength of the biomolecule, are to be characterized in details, and the other side is how expensive should the chemical evaluation be? At this moment, RCGM is seeing the issues and is in touch with both the FDA and the EMEA, and they are taking case by case decisions while trying to standardize the minimum information that is required to show how companies have characterized their products.”

“If we ask a big established company on this issue they will tell us to be strict, whereas a smaller company will suggest otherwise. What we are trying to do is being very scientific and come to a conclusion,” reported Express Pharma quoting Dr. Bhan.

The current practice:

Much water has flown down the bridge since the above interview was published. Nothing much has changed on ground regarding this critical issue, thus far. The industry sources allege that even today regulatory approval of biosimilar drugs (large molecules) are granted based on Phase III clinical trials, as specified in the schedule Y of the Drugs and Cosmetics Acts for the small molecules (chemicals) and that too conducted mostly on just 40 to 45 patients. At times the number of patients studied is even lesser. Immunogenicity study, which is so important for biosimilar drugs is, more often than not, overlooked. This could seriously compromise patients’ safety with such category of drugs.

Conclusion:

It is, indeed, quite surprising that in our country there is still no separate transparent and published guidelines for regulatory approval of Biosimilar drugs even when the World Health Organization (WHO) has come out with the same and India had actively participated in that exercise.
The question, therefore, comes to my mind whether the Biosimilar drugs manufactured in India would conform to international quality and safety standards, like in the U.K or what has been recently announced in the USA? If not, who will address the safety concerns of the patients administering these life saving medicines?

Such a concern gets vindicated by widely reported serious quality problems, detected by the drugs regulatory authorities, at some large and well known Biosimilar drug’s manufacturing units in India, in not too distant past and also from the condition of some vaccine manufacturing units in our country. The recent example of WHO cancelling the pre-qualification of ‘Shan 5’ (Shanta Biotech) vaccines for quality related problems, perhaps may help opening the eyes of our regulators, on the related patients’ safety issues arising out of regulatory laxity.

This issue assumes even greater importance considering the very recent development of the Department of Biotechnology (DBT) unfolding an interesting scheme to encourage development of biosimialr dugs in India by offering financial support to the domestic pharmaceutical and biopharmaceutical industry.

The proposed new regulatory pathway for the marketing approval of Biosimilar drugs in India will immensely help paving the way for the Biopharmaceuticals drugs manufacturers in India to adequately prepare themselves to grab a significant share of the fast emerging Biosimilar drugs markets, particularly, in Europe and the USA, in the years to come.

The Ministry of Health and the Department of Biotechnology of the Government of India should, therefore, urgently and jointly consider amending the Drugs & Cosmetics Acts of India accordingly and establish robust regulatory guidelines for marketing approval of biosimilar drugs in the country, acknowledging the widespread concern for patients’ safety.

Bt Bringal…health and food safety…agricultural independence…biodiversity, are all intertwined

Posted on by

Bacillus Thuringiensis (Bt) Brinjal has now become a subject of intensive debate for various important reasons. Bt Bringal is a genetically modified strain of Brinjal, developed by the premier seed company in India Mahyco in collaboration with the American major Monsanto. The main claim of such seed varieties is improving yield by protecting the crop from the pests.
The key concerns related to products like Bt Brinjals are in the following areas:

1. Health and Food Safety

2. Dependence on overseas companies year after year for agricultural products

3. Compromising ‘biodiversity’

4. Effectiveness of Bt products

Health and Food Safety:

The main focus of the debate revolves round the health and food safety concerns with such biotech food products. Environmentalists point out that the genetically modified foods while fed on rats have already shown fatal kidney and lung disorders.

Gilles-Eric Seralini, a French scientist has opined that the tests conducted by Mahyco for Bt Brinjal are unsustainable and would raise very serious health and food safety concerns.

Adverse safety results with Bt cotton, like respiratory tract related problems, skin allergy, immunological disorders etc., from many countries of the world further aggravate the health and food safety concerns with Bt Brinjal. Many experts have opined, as mentioned above, that such disorders could lead to even death with long term use of these products. It will perhaps be imprudent on the part of the civil society to take such ‘public health’ concerns lightly.

Alleged bias by GEAC:

Besides, health and food safety concerns many activists feel that the initial approval of Bt Bringal by the Genetic Engineering Approval Committee (GEAC) raises a suspicion of bias towards overseas Bt seed manufacturing companies.

Could it lead to Agriculture dependence on overseas companies?

Another important point that needs to be deliberated by all concerned is the impact of such technology producing ‘terminator gene’. Many apprehend that such a move by India could pose a threat to the agriculture of the country over a period of time, with Indian farmers buying these costlier varieties of seeds from the overseas companies year after year and being dependent on them for the same.

Since India does not recognize patents on life-forms, farmers will be required to pay a type of royalty to the manufacturer, usually known as ‘Trait Fee’. Such fees used to be levied for Bt cotton seeds. However, on this type of fees, in response to a petition filed by farmers in Andhra Pradesh against an international manufacturer and supplier, Monopolies and Restrictive Trade Practices Commission (MRTPC) gave its ruling in 2006, which is as follows:

“The trait fee being charged by the respondent not only imposes unjustified costs on the farmers by way of manipulation of prices but is also unreasonable in view of lack of competition.”

Many experts feel that such anti-competitive practices involving food products could lead to a different type of dependence on the overseas suppliers of Bt seeds, even if such products are found safe.

Further, concerns related to the control of such seeds and the lack of investment in the public sector for biotech research in this area should be urgently addressed.

The concern related to ‘Biodiversity’:

There is also another important concern related to ‘Biodiversity’. It has been reported that around 2500 varieties of Brinjal are available in India. Brinjal being a plant resulting from cross pollination, entry of Bt.Bringal could lead to genetic contamination affecting existence of many such locally grown varieties raising the contentious issue of ‘biodiversity’.

In the context of Bt Bringal, Dr. Manmohan Singh, the Prime Minister of India has recently issued a statement, as follows:

“It was agreed that biotechnology is an important option for higher agricultural productivity and ensuring food security. At the same time, we must ensure that it has no adverse effects on human and animal health and bio-diversity.”

“Keeping this in mind, the government will soon be moving forward in setting up a National Biotechnology Regulatory Authority which will inspire confidence and stimulate public and private investment in biotechnology.”

If ‘Food security’ is the issue, why choose Bt Brinjal?

However, if Bt products will help the nation to address the ‘food security’ issue, the question that will logically emerge, “why then Bt Brinjal?”

As far as I know, India is one of the largest producers of Brinjal in the world with so many varieties of it and there is no shortage of Brinjal in the country either. Thus ‘Food Security’ could hardly be an issue, at least in this case.

Effectiveness of Bt products:

We all have read the media reports related to many incidences of mass suicides by Indian farmers due to crop failures with Bt Cotton. The effectiveness claimed by the manufacturers of Bt cotton is now shrouded with doubts. The following report from ‘The Times of India’ dated March 7, 2010 vindicates this point:

“Bt cotton failed to thwart pests in Gujarat”. Monsanto also concedes, “During field monitoring in 2009, the Bt cotton variety used in four Gujarat districts – Amreli, Bhavnagar, Junagadh and Rajkot was found to attract the pink bollworm, a major pest that attacks cotton plantations”.

Such reports further strengthen the argument of the Environment Minister of India, Mr. Jairam Ramesh that Bt seed varieties should be evaluated with utmost care and precision before nationwide operationalization, for the reasons mentioned above.

Conclusion:

Be that as it may, I believe that uncontrolled entry of Bt products should NOT be encouraged in India without:

- Proper knowledge of their serious adverse effects on human and animal health on long term consumption

- Having scientific proof on their long term effectiveness

- Protecting agricultural independence of the country

- Encouraging indigenous biotech research in this field

- Satisfactorily addressing the concern related to ‘biodiversity’ of the nation.

With significant competitive edge should Global Biotech Companies consider entry into high potential ‘Biosimilar drugs’ business?

Posted on by

‘Biosimilar drugs’ – rapid future growth potential:
In most of the developed countries of the world, besides regulatory issues, ‘Biosimilar drugs’are considered a threat to the fast growing global biotech industry. However, many believe that innovative biotech companies can have a head start with all wherewithals at their disposal, compared to generic pharmaceutical companies, to convert this seemingly significant threat into a bright emerging opportunity and derive the best possible mileage out of such changing environment.

Sandoz (Novartis) – first to launch a ‘Biosimilar drug’ in the USA:

In mid 2006, US FDA approved its first ‘Biosimilar drug’; Omnitrope of Sandoz (Novartis) following a court directive in the U.S. Omnitrope is a copycat version of Pfizer’s human growth hormone, Genotropin. Interestingly, Sandoz (Novartis) had taken the U.S FDA to court as the regulatory approval of Omnitrope was kept pending by them, in absence of a defined regulatory pathway for ‘Biosimilar drugs’ in USA.

The CEO of Sandoz had then commented, “The FDA’s approval is a breakthrough in our goal of making high-quality and cost-effective follow-on biotechnology medicines like Omnitrope available for healthcare providers and patients worldwide.” Despite this event, no one at that time expected the U.S FDA to start commencing approval of other ‘Biosimilar drugs’ within the country.

‘Biosimilar drugs’ – emerging global interest:

Thereafter, many developments are fast taking place in the space of ‘Biosimilar drugs’, the world over. To fetch maximum benefits out of this emerging opportunity, India is also taking steps to tighten its regulatory reform process for ‘Biosimilar drugs’ to allay general fear and apprehensions regarding safety of such drugs, in absence of adequate clinical data for the specific protein substance.

Merck’s entry in ‘Biosimilar drugs’ business is through an acquisition:

In the west Merck announced its entry into the ‘Biosimilar drugs’ business on February 12, 2009, while announcing its acquisition of Insmed’s portfolio of ‘Biosimilar drugs’ for U.S$130 million in cash. Rich pipeline of follow-on biologics of Insmed is expected to help Merck to hasten its entry into global ‘Biosimilar drugs’ markets.

Current status of ‘Biosimilar drugs’ in the USA:

The new administration of President Barak Obama has expressed its strong intent to pave the way for regulatory guidelines for ‘Biosimilar drugs’ in the USA. To facilitate this process, the new draft legislation titled, “Promoting Innovation and Access to Life Saving Medicine Act” has already been introduced by the legislators of the country. This legislation, when will come into force would help define guidelines for approval of ‘Biosimilar drugs’ in the USA with just a five year exclusivity period to the innovative products, against a demand of 14 years by the global biotechnology industry.

Lucrative Global market potential for ‘Biosimilar drugs’:

It is estimated that only in the top two largest pharmaceutical markets of the world, USA and EU, sales of ‘Biosimilar drugs’ will record a turnover of U.S$ 16 billion in next two years and around U.S$ 60 billion by year 2010, when about 60 biotech products will go off-patent.

Opportunity for the Indian biotech companies:

Such a lucrative business opportunity in the west will obviously attract many Indian players, like, Biocon, Dr. Reddy’s Labs, Ranbaxy, Wockhardt etc, who have already acquired expertise in the development of ‘Biosimilar drugs’ in India like, erythropoietin, insulin, monoclonal antibodies, interferon-alfa. Domestic Indian biotech players are not only marketing these products in India but also exporting them to other non/less-regulated markets of the world.

Indian Companies are fast preparing to take a sizable share of the global pie of ‘Biosimilar drugs’ market:

Ranbaxy in collaboration with Zenotech Laboratories is engaged in global development of Granulocyte Colony-Stimulating Factor (GCSF) formulations. Wockhards is expected to enter into the Global ‘Biosimilar drugs’ market by 2010. Dr. Reddy’s Laboratories and Biocon are also preparing themselves for global development and marketing of insulin products, GCSF and streptokinase formulations.

Government of India funding for development of ‘Biosimilar drugs’ in India:

It has been reported that the Department of Biotechnology (DBT) of the Government of India has a proposal for funding of U.S$ 68 million through public private partnership (PPP) initiatives, where soft loans at the rate of interest of just 2% will be made available to the Indian biotech companies for development of ‘Biosimilar drugs’. Currently DBT spends around U.S$200 million annually towards biotechnology related initiatives.

Advantage India:

Experience in conforming to stringent U.S FDA manufacturing standards, having largest number of U.S FDA approved plant outside USA; India has acquired a great advantage in manufacturing similar high technology products in India. Significant improvement in conformance to Good Clinical Practices (GCP) standards in India offers additional advantages.

Two available choices for the innovator companies:

With increasing global cost-containment pressures within the healthcare space, emergence of a lucrative global ‘Biosimilar drugs’ market with appropriate defined regulatory pathway in place is inevitable now.

Major global research based companies will now have two clear choices in the fast evolving situation. The first choice is the conventional one of competing with the ‘Biosimilar drugs’ in all important markets of the world. However, the second choice of jumping into the fray of ‘Biosimilar drugs’ business keeping focus on R&D undiluted, appears to be more prudent to me and perhaps will also make a better business sense. Only future will tell us, which of these two business senses will prevail, in the long run for the global biotech companies.

Fixed Dose Combination’ drugs market in India is growing faster – are there enough regulatory checks and balances to prevent market entry of ‘irrational combinations’ to ensure patients’ safety?

Posted on by

The WHO Model of FDCs:The 2005 ʹProcedure to update and disseminate the WHO Model List of Essential Medicines, Criteria for Selection‘ includes the following statement regarding fixed dose combination products (FDCs):ʺMost essential medicines should be formulated as single compounds. Fixed‐dose combination products are selected only when the combination has a proven advantage over single compounds administered separately in therapeutic effect, safety, and adherence or in delaying the development of drug resistance in malaria, tuberculosis and HIV/ AIDS.ʺ

FDCs need to demonstrate clinical efficacy and safety beyond that for the individual drugs given alone. They would also need to ‘demonstrate bioequivalence of the single combined dose unit with the components administered in the same doses separately but concomitantly’.

‘Adherence’ aspect of WHO Model for FDCs is also important. Problems with ‘adherence’ could lead to inadequate and inconsistent dosing, which in turn could lead to development of drug resistance. FDCs, therefore, are expected to improve compliance reducing the risk of development of drug resistance.

However, one of the major disadvantages with the FDCs is lack of flexibility in adjusting dose of individual ingredients, even if it is required for some patients. Internationally, most popular example is the FDCs of antiretroviral drugs for HIV infected patients like, Combivir, Trzivir, Kaletra etc. Besides, there are FDCs for various other disease areas, like, infections, respiratory and cardiovascular disorders etc.

New FDCs are patent protected in the USA:

In the western world, like the USA, new FDCs may also get patent protection. A company may obtain marketing exclusivity for a new FDC even when individual active ingredients go off patent. However, in India FDCs cannot be patented as per Patent Acts of India 2005.

Market attractiveness for FDCs in India:

In India the market for FDCs is very large and growing much faster, in sharp contrast to the western world. Because of growing market demand, pharmaceutical companies in India tend to market FDCs of all different permutations and combination, at times even crossing the line of a ‘sound medical rationale’. For this reason, we find in the website of ‘Central Drugs Standard Control Organization’ (CDSCO), the banned list of so many FDCs.

Lack of regulatory compliance has created a messy situation with FDCs in India:

Introduction of new FDCs does not only warrant a ‘sound medical rationale’ but also ‘strict conformance to all prescribed regulatory requirements’ for the sake of patents’ safety.

To check unfettered market introduction of potentially harmful FDCs, the Ministry of Health issued a Notification in September 1988, including FDCs in Rule 122 E of the Drugs & Cosmetics Rules (D&CR) 1945. In effect, it removed the powers of the State FDAs to give manufacturing or marketing approval of FDCs. After the notification was issued, all manufacturers/marketers of all FDCs are required to apply only to the Drug Controller General of India (DCGI) under Rule 122E of the D&CR 1945 as a new drug, along with the stipulated fees by way of a Treasury Challan.

Since this entire process entails relatively more regulatory data generation, besides the time and expenses involved, the above Rule was continuously and deliberately broken and manufacturing and marketing approvals were routinely sought and obtained from the State FDAs. Many believe that the State FDAs were equally responsible for knowingly flaunting the Law, as were the pharmaceutical companies.

Patients’ safety – the key concern:

This complicity resulted in the market being flooded with ‘irrational combinations’ which posed a real threat to patients’ safety. The state FDAs were reminded of the Notification by the earlier DCGI. 294 FDCs got caught in this dispute. The important issue of patients’ safety in that process got converted into a legal issue, as many FDC manufacturers chose to go to the court of law to redress their grievances in this matter.

Untangling the messy knot:

As the issue got trapped into various prolonged litigations, the current DCGI took initiative of resolving this contentious issue with the help of an expert committee, involving the manufacturers.

This subcommittee cleared 48 FDCs under ‘similar FDCs already approved’, after discussing the merits and demerits, including pharmacodynamics, pharmacokinetics, side effects, dosage, medical rationale etc. of each ingredient and the combinations. The decision of the Sub Committee was then submitted to the Drug Technical Advisory Board (DTAB).

After formal approval of DTAB, a notification is expected to be issued subsequent to which each of these combinations will be construed to be a new drug and any company wishing to market/manufacture the formulation will require submitting its Application in Form 44 to the DCGI to get approval in Form 45. The process will be completed after the balance 142 FDCs, which need further examination, are individually approved.

This issue sends a clear signal to all concerned that resorting to any form of shortcuts to bypass strict adherence to prescribed regulatory requirements, could seriously jeopardise the patients’ safety. The number of FDCs banned by CDSCO and also ban of those FDCs agreed and accepted by the industry without any challenge during the above process, will vindicate this point.

Solving the current logjam is not enough:

Solving the current logjam on FDCs by the DCGI is a onetime exercise and will perhaps clear a serious mess-up created over a long period of time. It can definitely not be an ongoing process. Neither will it be desirable. There is an absolute and urgent need to follow the WHO Model for FDCs, in India, as indicated above, through appropriate regulatory processes. At the same time, the DCGI should ensure strict compliance of the Notification issued by Ministry of Health on FDCs, in September 1988. Otherwise, unchecked entry of FDCs of all possible permutations and combinations could pose a serious threat to patients’ interest and safety.

Meeting unmet needs of the patients with high quality drugs of scientifically proven high efficacy and safety profile should always define the purpose of existence of the pharmaceutical industry. Any patients’ safety related issue deserves no scope for any compromise.

Biosimilar Drugs -A raging scientific debate with mounting global commercial interest

Posted on by

On December 11, 2008, Reuters reported that two days after Merck & Co. announced a major push into generic versions of biotechnology medicines, Eli Lilly & Co. signaled similar aspirations. This report raised many eyebrows in the global pharmaceutical industry, in the midst of a raging scientific debate on this issue. Be that as it may, many felt that this announcement ushered in the beginning of a new era. An era of intense future competition with Biosimilar drugs in the world market with immense commercial interest.Globally, the scenario for generic versions of biotechnology medicines, which are called Biosimilars, Biogenerics or follow-on Biologics, started heating up when Merck announced that the company expects to have atleast 5 follow-on biologics in the late stage development by 2012. The announcement of both Merck and Eli Lilly surprised many, as the largest pharmaceutical market of the world – the U.S.A is yet to approve the regulatory pathway for generic biologic medicines. In the developed world, European Union (EU) has taken a lead towards this direction by already having a system in place for regulatory approval of Biosimilar drugs in 2003.What then prompts the research based global pharmaceutical companies like Merck and Eli Lilly to step into the arena of Biosimilar medicines? Is it gradual drying up research pipeline together with skyrocketing cost of global R&D initiatives?

The future business potential of Biosimilar medicines:

Currently, over 150 different biologic medicines are available in the Global Pharmaceutical market. However, the low cost Biosimilar drugs are available in just around 11 countries of the world, India being one of them. Supporters of Biosimilar medicines are indeed swelling as time passes by. At present, the key global players are Sandoz (Novartis), Teva, BioPartners, BioGenerix (Ratiopharm) and Bioceuticals (Stada). This market is expected to develop slowly because of regulatory hurdles in the major countries of the world.

Very recently, the EU has approved Sandoz’s (Novartis) Filgrastim (Neupogen brand of Amgen), which is prescribed for the treatment of Neutropenia. With Filgrastim, Sandoz will now have 3 Biosimilar products in its portfolio.

Raging debate on Biosimilar Drugs still continues:

The debate is centered on the argument that like small chemical molecules is it possible to replicate large biological molecule of the innovator? It is widely believed that a protein cannot be absolutely replicated. How could possibly then Biosimilar drugs be considered equivalent to the original product by a regulator and marketing approval be granted to them without full scale clinical trials ignoring safety concerns of the patients? In favor of this argument some refer to the problem of red cell aplasia that affected many patients administering Johnson & Johnson’s Exprex (Epoetin) after only a minor change made in its manufacturing procedure.

Hurdles to cross for future Market entry of Biosimilar Drugs:

Emergence of second generation branded biosimilar products such as PEGylated products Pegasys and PegIntron (peginterferon alpha) and Neulasta (pegfilgrastim), and insulin analogs etc. have the potential to reduce the market size for first generation Biosimilar drugs creating significant entry barrier.

Even otherwise, the barriers to market entry of Biosimilar drugs are much higher than any small molecule generic drug. In the markets within EU, many companies face the challenge of higher development costs for biosimilar drugs because of stringent regulatory requirements and greater lead time for product development. Navigating through such a tough regulatory environment will demand a different type of skill sets from the generic companies not only in areas of clinical trials and pharmacovigilance, but also in areas of manufacturing and marketing. Consequently, the investment needed to take Biosimilar drugs from clinical trials to launch in the developed markets, will indeed be quite significant.

Current Scenario in the U.S:

Recently in the U.S.A, the new, widely reported, biotechnology policy of President Barak Obama has become one of the most closely watched healthcare policy initiatives of the country. It is expected that such a policy will help facilitate regulatory approval process of Biosimilar drugs in the USA by end 2009. This new policy initiative could have a major impact on many biotech companies who will face new generic competition, rather quickly. On the other hand, it will prove to be a boon to the new entrants in this market like, Merck and Eli Lilly, besides the existing ones.

Global Market Potential of Biosimilar Drugs:

The biosimilar drug market in the world is estimated to be around U.S. $ 16 billion by 2011. Currently, off-patent biologic blockbusters including Erythropoietin offer an excellent commercial opportunity in this category of drugs. By 2013, about 10 branded biologics with a total turnover of around U.S. $ 15 billion will go off-patent.

Biosimilar Drugs in India:

Sales of biosimilar drugs in India are estimated to be around U.S. $ 4 billion by 2011.

Biosimilar drugs fall under high growth segment within Indian pharmaceutical Industry. Recombinant vaccines, erythropoietin, recombinant insulin, monoclonal antibody, interferon alpha, granulocyte cell stimulating factor like products are manufactured by a number of domestic biotech companies like Biocon, Panacea Biotech, Wockhardt, Emcure, Shantha Biotech, Bharat Biotech, Serum Institute of India, Dr. Reddy’s, Ranbaxy, etc. The ultimate objective of all these Indian companies, I am sure, will be to get regulatory approval of such products in the EU and then in the U.S. when the time comes.

It is worth mentioning here that to give a fillip to the Biotech Industry in India, the National Biotechnology Board was set up by the Government of India under the Ministry of Science and Technology in 1982 and the Department of Biotechnology (DBT) came into existence in 1986. The DBT now spends around US$ 200 million annually to develop biotech resources in the country and have been making reasonably good progress. The DBT is reported to have undertaken an initiative to prepare regulatory guidelines for Biosimilar Drugs, which is expected to conform to international quality and patients’ safety requirements.

The points to ponder with the Biosimilar Drugs in India:

It is, indeed, quite surprising that in India there is still no separate transparent and published guidelines for regulatory approval of Biosimilar drugs, although the Drug Controller General of India (DCGI) seems to have a different view in this matter. The Drugs and Cosmetics Acts of India have no separate provisions either, for Biosimilar Drugs. In a situation like this, we find that many Biosimilar Drugs are still getting regulatory approval in India.

Currently India supplies 30% by volume of the global requirements of generic drugs both in regulated and non-regulated markets. In the regulated markets like North America and EU, for small molecule generic products, Indian manufacturers conform to the global safety and efficacy standards by getting these products approved by the most stringent regulators of the world like, U.S. FDA, MHRA (Medicines and Healthcare products Regulatory Agency) etc. The very fact that none of the Biosimilar drugs developed in India could get approval in the EU as yet, may well suggest that the stringent regulatory requirements for both efficacy and patients’ safety followed in the EU for Biosimilar drugs, could not be met by the Indian manufacturers, as yet. The question, therefore, comes to my mind whether the Biosimilar drugs manufactured in India conform to international quality and safety standards? If not, who will address the safety concerns of the patients who are or will be administering these medicines?

Such a concern gets vindicated by widely reported serious quality problems, detected by the drug regulatory authorities, at some large and well known Biosimilar drugs manufacturing units in India and also from the condition of some vaccine manufacturing units in our country.

India needs to manufacture the world class Biosimilar drugs conforming to the highest efficacy and patients’ safety standards, just the way Indian pharmaceutical manufacturers have demonstrated with ‘made in India’ generic drugs, the world over. The Indian drug regulatory authority should now take some important initiative with the publication of world class Biosimilar drugs regulatory approval guidelines, may be following the similar process as what we see in the EU.

Currently, experts from India are participating towards preparation of ‘WHO Guidelines’ for Biosimilar Drugs. The progress made towards this direction is yet to be ascertained. Simultaneously, the DBT is reported to have under taken an independent initiative to prepare similar guidelines, the progress of which is also yet to be known.

Before other developed markets open up for Biosimilar drugs, if India can align itself with its own world class regulatory standards for the same, yet another significant export opportunity could be created for the country, competing with the best performers of the world in this category.

Meanwhile, it will only be good to know that like many other initiatives, India has taken one more important initiative to address this important issue, for the sake of humanity. As the existing process of granting regulatory approval for Biosimilar drugs continues in India, the lurking fear towards patients’ safety with such drugs will remain unabated with a large majority of experts in this field.
