Biosimilar Drugs: First Indian Foot Print In An Uncharted Frontier

Posted on by

A homegrown Indian biologic manufacturer is now about to leave behind its first foot-print, with a ‘made in India’ biosimilar drug, in one of the largest pharma market of the world. This was indeed an uncharted frontier, and a dream to realize for any Indian bio-pharma player.                                                      

On March 28, 2016, by a Press Release, Bengaluru based Biocon Ltd., one of the premier biopharmaceutical companies in India, announced that the Ministry of Health, Labour and Welfare (MHLW) of Japan has approved its biosimilar Insulin Glargine in a prefilled disposable pen. The product is a biosimilar version of Sanofi’s blockbuster insulin brand – ‘Lantus’.

The Company claims that Glargine is a high quality, yet an affordable priced product, as it will reportedly cost around 25 percent less than the original biologic brand – Lantus. This ‘made in India’ biosimilar product is expected to be launched in Japan in the Q1 of 2017. Incidentally, Japan is the second largest Glargine market in the world with a value of US$ 144 Million. Biocon will co-market this product with its partner Fujifilm.

Would it be a free run? 

Although it is a very significant and well-deserved achievement of Biocon, but its entry with this biosimilar drug in Japan’s Lantus market, nevertheless, does not seem to be free from tough competition. This is because, in 2015, both Lilly and Boehringer Ingelheim also obtained Japanese regulatory approval for their respective biosimilar versions of Lantus. In the same year, both these companies also gained regulatory approval from the US-FDA, and the European Medicine Agency (EMA) for their respective products.

Moreover, Sanofi’s longer acting version of Lantus – Lantus XR, or Toujeo, to treat both Type 1 and Type 2 diabetes, has already been approved in Japan, which needs to be injected less, expectedly making it more convenient to patients.

Key barriers to a biosimilar drug's success: 

Such barriers, as I shall briefly outline below, help sustaining monopoly of the original biologic even after patent expiry, discourage investments in innovation in search of biosimilars, and adversely impacts access to effective and much less expensive follow-on-biologics to save patients’ precious lives. 

These barriers can be broadly divided in two categories: 

A. Regulatory barriers:

1. Varying non-proprietary names:

A large number of biosimilar drug manufacturers, including insurers and large pharmacy chains believe, just as various global studies have also indicated that varying non-proprietary names for biosimilars, quite different from the original biologic, as required by the drug regulators in the world’s most regulated pharma markets, such as, the United States, Europe, Japan, and Australia, restrict competition in the market for the original biologic brands. 

However, the innovator companies for biologic drugs hold quite different views. For example, Roche (Genentech), a developer of original biologic, reportedly explained that “distinguishable non-proprietary names are in the best interest of patient safety, because they facilitate Pharmacovigilance, and mitigate inadvertent product substitution.”

Even, many other global companies that develop both original biologic and also biosimilar products such as, Amgen, Pfizer and others, also reportedly support the use of ‘distinguishable nonproprietary names’.

That said, the Biosimilars Council of the Generic Pharmaceutical Association argues that consistent non-proprietary naming will ensure robust market formation that ultimately supports patient access, affordability, Pharmacovigilance systems currently in place and allow for unambiguous prescribing, 

2. Substitution or interchangeable with original biologics:

Besides different ‘non-proprietary names’, but arising primarily out of this issue, automatic substitution or interchangeability is not permitted for biosimilar drugs by the drug regulators in the major pharma markets of the world, such as, the United States, Europe and Japan.

The key argument in favor of interchangeability barrier for biosimilar drugs is the fact that the biological drugs, being large protein molecules, can never be exactly replicated. Hence, automatic substitution of original biologic with biosimilar drugs does not arise. This is mainly due to the safety concern that interchangeability between the biosimilars and the original biologic may increase immunogenicity, giving rise to adverse drug reactions. Hence, it would be risky to allow interchangeability of biosimilar drugs, without generating relevant clinical trial data.

On the other hand, the Generic Pharmaceutical Association (GPhA) and the Biosimilars Council, vehemently argue that a biosimilar drug has a lot many other unique identifying characteristics “including a brand name, company name, a lot number and a National Drug Code (NDC) number that would readily distinguish it from other products that share the same nonproprietary name.”

Further, the interchangeable status for biosimilar drugs would also help its manufacturers to tide over the initial apprehensions on safety and quality of biosimilar drugs, as compared to the original ones.

3. 12-year Data Exclusivity period for biologics in the United states:

Currently, the new law for biologic products in the United States provides 12 years of data exclusivity for a new biologic. This is five years more than what is granted to small molecule drugs. 

Many experts believe that this system would further delay the entry of cost-effective biosimilar drugs, restrict the biosimilar drug manufacturers from relying on the test data submitted to drug regulator by the manufacturers of the original biologic drugs while seeking marketing approval.

A rapidly evolving scenario in the United States:

The regulatory space for approval of biosimilar drugs is still evolving in the Unites States. This is vindicated by the fact that in March 2016, giving a somewhat positive signal to the biosimilar drug manufacturers, the US-FDA released another set of a 15-page draft guidelines on how biosimilar products should be labeled for the US market. Interestingly, it has come just around a year of the first biosimilar drug approval in the United States – Zarxio (filgrastim-sndz) of Novartis.

The US-FDA announcement says that all ‘comments and suggestions regarding this draft document should be submitted within 60 days of publication in the Federal Register of the notice announcing the availability of the draft guidance.’ Besides labeling issues, this draft guidance document, though indicates that the ‘interchangeability’ criteria will be addressed in the future, does not still throw enough light on how exactly to determine ‘interchangeability’ for biosimilar drugs.

That said, these key regulatory barriers are likely to continue, at least in the foreseeable future, for many reasons. The biosimilar drug manufacturers, therefore, would necessarily have to work within the set regulations, as applicable to different markets of the world.

I deliberated a related point in my article of August 25, 2014, titled “Scandalizing Biosimilar Drugs With Safety Concerns” 

B. Prescribers’ skepticism:  

Initial skepticism of the medical profession for biosimilar drugs are, reportedly, due to the high voltage advocacy of the original biologic manufacturers on the ‘documented variability between original biologic and biosimilars. Which is why, any substitution of an original biologic with a related biosimilar drug could lead to increase in avoidable adverse reactions.

‘The medical platform and community QuantiaMD’, released a study just around September 2015, when by a Press Release, Novartis announced the launch of the first biosimilar approved by the US-FDA – Zarxio(TM) (filgrastim-sndz). However, in 2006, Novartis after suing the US-FDA, got the approval for its human growth hormone – Omnitrope, which is a biosimilar of the original biologic of Genentech and Pfizer. At that time a clear regulatory guideline for biosimilar drugs in the United States, was not in place.

The QuantiaMD report at that time said, “Only 12% of prescribing specialists are ‘very confident’ that biosimilars are as safe as the original biologic version of the drug. In addition, a mere 17% said they were ‘very likely’ to prescribe a biosimilar, while 70% admitted they were not sure if they would.” 

Since then, this scenario for biosimilar drugs is changing though gradually, but encouragingly. I shall dwell on that below.

The major growth drivers:

The major growth drivers for biosimilars, especially, in the world’s top pharmaceutical markets are expected to be:

  • Growing pressure to curtail healthcare expenditure
  • Growing demand for biosimilar drugs due to their cost-effectiveness
  • Rising incidences of various life-threatening diseases
  • Increasing number of off-patent biologics
  • Positive outcome in the ongoing clinical trials
  • Rising demand for biosimilars in different therapeutic applications, such as, rheumatoid arthritis and blood disorders. 

This in turn would probably usher in an unprecedented opportunity for the manufacturers of high quality biosimilar drugs, including in India.

Unfolding a huge emerging opportunity with biosimilars: 

This unprecedented opportunity is expected to come mainly from the world’s three largest pharma market, namely the United States, Europe and Japan, due to very high prices of original biologic drugs, and simultaneously to contain rapidly escalating healthcare expenditure by the respective Governments. 

Unlike in the past, when the doctors were apprehensive, and a bit skeptic too, on the use of new biosimilars, some new studies of 2016 indicate a rapid change in that trend. After the launch of the first biosimilar drug in the US, coupled with rapidly increasing incidences of various complex, life-threatening diseases, better knowledge of biosimilar drugs and their cost-effectiveness, doctors are now expressing much lesser concern, and exhibiting greater confidence in the use of biosimilars in their clinical practice.

Yet another, March 2016 study indicates, now only 19.5 percent of respondents feel little or no confidence in the use of biosimilar monoclonal antibodies compared to 61percent of respondents to a previous version of the survey undertaken in 2013 by the same market research group. The survey also shows that 44.4 percent of respondents consider that the original biologic and its biosimilar versions are interchangeable, as compared with only 6 percent in the 2013 survey.

As a result of this emerging trend, some global analysts of high credibility estimate that innovative biologic brands will lose around US$110 billion in sales to their biosimilar versions by 2025.

Another March, 2016 report of IMS Institute for Healthcare Informatics states that lower-cost biosimilar versions of complex biologic, could save the US and Europe’s five top markets as much as US$112 billion by 2020,

These encouraging developments in the global biosimilar arena are expected to encourage the capable Indian biosimilar drug players to invest in this high-tech format of drug development, and reap a rich harvest as the high priced blockbuster biologic brands go off-patent.

Conclusion:

Putting all these developments together, and considering the rapidly emerging scenario in this space, it now appears that challenges ahead for rapid acceptance of biosimilar drugs though are still many, but not insurmountable, at all.

The situation necessitates application of fresh and innovative marketing strategies to gain doctors’ confidence on biosimilar medicines, in total conformance with the regulatory requirements for the same, as they are, in the most important regulated markets of the world.

It goes without saying that success in the generation of enough prescriptions for biosimilar drugs is the fundamental requirement to benefit the patients, which, in turn, would lead to significant savings in health care cost, as estimated above, creating a win-win situation for all, in every way.

As more innovator companies start joining the biosimilar bandwagon, the physicians’ perception on these new varieties of medicines, hopefully, would also change, sooner.

Biocon’s grand announcement of its entry with a ‘made in India’ biosimilar drug in one of the word’s top three pharma markets, would probably be a great encouragement for all other Indian biosimilar drug manufacturers. It clearly showcases the capabilities of an Indian drug manufacturer to chart in an uncharted and a highly complex frontier of medicine.

Biosimilar Drugs: Why Prescriptions Aren’t Still Enough?

Posted on by

On September 3, 2015, in a Press Release, Novartis announced, “Zarxio(TM) (filgrastim-sndz) is now available in the United States. Zarxio is the first biosimilar approved by the US Food and Drug Administration (FDA) and the first to launch in the US.” Zarxio is being marketed by the generic drug unit of Novartis – Sandoz.

The company highlighted: “With the launch of Zarxio, we look forward to increasing patient, prescriber and payor access to filgrastim in the US by offering a high-quality, more affordable version of this important oncology medicine.” This statement may be interpreted as an acknowledged of a research based global pharma major that high-priced biologics create a notable access barrier to a large number of patients, even in a rich country such as the United States. It also underscores the increasing prescription opportunities for cheaper biosimilar drugs.

Zarxio will initially be available with a 15 percent discount. This needs to be viewed against usual price drop of around 20-30 percent for biosimilar drugs in Europe, as compared to the original molecules. It is expected that price differences between biosimilar drugs and the original ones, would vary widely from as low as 10 percent to a hefty 60 percent, in the global markets.

Prior to Novartis’s Press Release, USFDA announced Zarxio’s approval in a separate ‘FDA News Release on March 6, 2015, indicating that it can be prescribed by a health care professional for:

  • patients with cancer receiving myelosuppressive chemotherapy
  • patients with acute myeloid leukemia receiving induction or consolidation chemotherapy
  • patients with cancer undergoing bone marrow transplantation
  • patients undergoing autologous peripheral blood progenitor cell collection and therapy a
  • patients with severe chronic neutropenia.

Though such types of drugs are available in the important markets such as, Europe, Australia and India, the launch of Zarxio heralds the dawn of a new era of biosimilar drugs in the United States – the numero uno of the global pharma market.

Incidentally, USFDA’s approval of biosimilar drugs is an outcome of a relatively recent healthcare reform in the United States, when President Obama signed into law the ‘Affordable Care Act’ on March 23, 2010.

The key benefit:

In its above ‘Press Release’, Novartis captured well the key benefits of biosimilar drugs , as follows:

“While biologics have had a significant impact on how diseases are treated, their cost and co-pays are difficult for many patients and the healthcare budget in general.  Biosimilars can help to fill an unmet need by providing expanded options, greater affordability and increased patient access to life-saving therapies.”

Major growth drivers:

According to July 2015 report of ‘MarketsandMarkets (M&M)’ the global biosimilars market is expected to grow to US$6.22 Billion by 2020 from US$2.29 Billion in 2015, growing at a CAGR of 22.1 percent from 2015 to 2020.

The major growth drivers of the global biosimilars market are expected to be:

  • Growing pressure to curtail healthcare expenditure
  • Growing demand for biosimilar drugs due to their cost-effectiveness
  • Rising incidences of various life-threatening diseases
  • Increasing number of off-patented biologics
  • Positive outcome in the ongoing clinical trials
  • Rising demand for biosimilars in different therapeutic applications such as rheumatoid arthritis and blood disorders.

European Union (EU) had a head start of 5 to 7 years to put its regulatory pathway for biosimilar drug development and approval process. Thus, at present practically most the entire value sales of biosimilar drugs take place in the EU.

As, cheaper biosimilars would continue to hit the US market, insurance companies are expected to encourage the use of such drugs instead of highly expensive original ones.

According to Express Scripts report released in December 2014, the US healthcare system could clock savings in drug costs around US$250 billion in the first decade of availability of biosimilars drugs and the approval of Zarxio would help patients saving more than US$5 billion in the the world’s largest market for biologics.

By 2020, several blockbuster biological products with global sales of more than US $67 billion would go or are going off-patent, creating great opportunities for biosimilar drugs the world over. Some of these drugs are Avastin (Roche), Humira (AbbVie), Synagis (AstraZeneca), Aranesp (Amgen) and Enbrel (Amgen, Pfizer).

However, the crux of its success, to a great extent, would lie on physicians’ confidence to prescribe large molecule biosimilar drugs, as these are new and not exact replicas of the original biologic molecules, unlike the small molecule generic drugs.

Possible growth barriers:

The success requirements of large molecule biosimilar drugs would not mimic the same for small molecule generics, anywhere in the world.

In my view, there are two types of critical barriers to success with biosimilars, both tangible and intangible in nature.

The same M&M report lists the following factors as possible tangible barriers to fast growth of biosimilar drugs:

  • High manufacturing complexities and costs
  • Stringent regulatory requirements in countries
  • Innovative strategies by biologic drug manufacturers to restrict the entry of new players

I would very briefly touch upon each one of these, hereunder:

I. High manufacturing complexities and costs:

This is primarily because, the therapeutic characteristics of biosimilar drugs are significantly influenced by their manufacturing methods. For example, it is quite possible that based on the manufacturing system that is adopted, the same starter ingredients may give substantially different results.

II. Stringent regulatory requirements:

Among many other stringent regulatory requirements, I would highlight in this article just the following two:

A. The labeling:

It is noteworthy that USFDA has named Zarxio with the placeholder nonproprietary name “filgrastim-sndz” and not as ‘filgrastim’, the nonproprietary name for Amgen’s, Neupogen, for which Zarxio has been approved as a biosimilar.

To quickly recapitulate its background, in July 2014, the World Health Organization (WHO), which oversees the system of International Nonproprietary Names (INN), recommended that biosimilar drugs would receive the same nonproprietary name, but with a four-letter code at the end.

This is primarily because, innovator biologic drug companies and also some doctors’ groups argue that molecular structures of biosimilar drugs are similar, but not exact replicas of the original ones. Hence, there is a need to differentiate them, while assigning INN.

They reiterate that giving biosimilars the same INN as the original biologic molecule may cause confusion among both the doctors and the patients. It could also make the tracking of adverse reactions, as and when these will be reported, more challenging.

Consequently, it has now been accepted by the regulators that biosimilars would receive the same nonproprietary name but with a four-letter code at the end to differentiate such drugs from the original biologics.

B. Interchangeability:

The above labelling issue, in turn, creates a barrier to possible interchangeability or automatic substitution of expensive original biologics with much cheaper equivalent of biosimilar drugs. I reckon, this could pose a critical obstacle in the initial take-off of the later.

According to a July 4, 2015 article, titled “Fate of cost-saving biosimilar drugs may hinge on naming policy”, published in ‘Modern Healthcare’, the USFDA has the following two pathways for licensing of biosimilar drugs:

  • For being designated as “similar” in efficacy and safety to an original biologic.
  • For being approved as being “interchangeable,” which requires a much higher review standard and could take years and millions of dollars to obtain the needed clinical trial data.

According to this article, none of the biosimilar products currently under USFDA review are in the interchangeable pathway.

III.  Innovative strategies to restrict entry of new players:

All the above innovative strategic moves and arguments, where biologic drug manufacturers are allegedly involved, may seriously restrict not just the entry of newer biosimilars, but also their faster prescription throughput.

Safety concern (immunogenicity):

Additionally, a critical safety concern on biosimilar drugs is being raised by the manufacturers of original biologics. This concern involves immunogenicity, which means the way a biosimilar drug provokes an immune response in the body. Original biologic drug manufacturers contend, since biosimilar molecules are not exactly the same as originals and their long term safety, related to immunogenicity, has not been tested, these drugs cannot be construed as having the same safety profile as the innovators’ biologics.

Besides, ‘Free-Trade-Agreements (FTAs)’ are also likely to be cleverly used by the original biologic drug manufacturers through their respective Governments, to the extent possible, for safeguarding the beachhead from the marketing onslaught of biosimilar drugs.

A perception barrier too:

Here comes an important perception-based intangible barrier to desirable prescription growth for biosimilar drugs.

Probably gauging it, post Zarxio launch, none other than the CEO of Novartis – Joe Jimenez, reportedly said: “He’s not expecting too much of a splash before 2020.”

This is understandable, as the doctors’ favorable disposition towards biosimilar drugs would be a crucial factor for prescription growth of these medicines.

A recent doctor community survey from QuantiaMD primarily captures the doctors’ thoughts and feelings on biosimilar drugs. This study was done with 300 specialists and primary care physicians.

Some of the notable findings of the report are as follows:

  • While 78 percent of the doctors polled said they were familiar with the term “biosimilar,” only 38 percent could name a biosimilar that’s under consideration for USFDA approval and would be relevant to their patient population.
  • Only 33 percent could name a biosimilar at all.

Researchers then narrowed down the original 300 physicians polled into a group of 120 “prescribing specialists.” This group of 120 doctors are currently prescribing biologics and most likely to prescribe biosimilar drugs in the years ahead. The study reported:

  • Only 17 percent of that segment said they are “very likely” to prescribe biosimilars.
  • And 70 percent said they either aren’t sure or are “somewhat likely’” to prescribe a biosimilar.
  • Only 12 percent of prescribing specialists are “very confident” that biosimilars are as safe as the original biologic version of the drug.

That said, 12-year ‘Data Exclusivity’ period for biologics in the United States, is one additional barrier to early introduction of cheaper biosimilar drugs, as considered by many.

On this issue GPhA – the generic drug makers’ group in America reportedly issued a statement, criticizing a paper of Biotechnology Industry Organization (BIO), saying:

“Market exclusivity acts as an absolute shield to their weak patents. Thus, from a practical perspective, extending market exclusivity beyond the Hatch-Waxman period would block the introduction of generic competition for almost 20 years, derailing any potential cost savings by Americans.”

The challenges ahead:

Considering all these together, the challenges ahead for quick acceptance of biosimilar drugs are indeed mind-boggling. The situation necessitates enough innovative and painstaking work by all concerned to gain the doctors’ confidence on biosimilar medicines. It goes without saying that success in generation of enough prescriptions for these drugs is the fundamental requirement to benefit the patients, which, in turn, would lead to significant savings in health care cost, as estimated above.

As more innovator companies start joining the biosimilar bandwagon, the physicians’ perception on these medicines, hopefully, would change sooner.

The status in India:

Although it appears strange, but a fact nonetheless. Biosimilar drugs approved in India till August 2012, followed the requirements of the regulators as provided mostly in the Drugs and Cosmetics Act for small molecule drugs, which are incidentally quite a different kettle of fish.

According to GaBI-online, the first locally produced biosimilar drug was approved and marketed in the year 2000. India announced implementation of its ‘Guidelines’ for ‘Similar Biologics’ much later, on September 15, 2012.

Indian ‘Guidelines’ for ‘Similar Biologics’ were jointly developed by the Department of Biotechnology (DoB) and the Central Drugs Standard Control Organization (CDSCO). The ‘Guidelines’ outline requirements for pre-clinical evaluation of biological products, claiming ‘similar to already approved biologics’. Thus, Indian regulators will partly rely on data from the already approved products to ensure safety, purity, potency and effectiveness of these drugs.

A wide variety:

A wide variety of biosimilar drugs have been approved and marketed in India, since then.

According to International Journal of Applied Basic Medical Research (2014 Jul-Dec; 4.2: 63–66), biosimilars in India consist primarily of vaccine, monoclonal antibodies, recombinant proteins and diagnostics, insulin, erythropoietin, hepatitis B vaccine, granulocyte colony stimulating factor, streptokinase, interferon alpha-2B and epidermal growth factor receptor.

The above article states that there are about 100 biopharmaceutical companies actively involved in research and development, manufacturing and marketing of biosimilar therapeutic products in India. Only 14 therapeutic drugs (similar biologics) were available in 50 brands in 2005. This number had grown to 20 therapeutic drugs in 250 brands in 2011.

The status of similar biologics approved and marketed in India is elaborated in this Table 1.

Some of the key Indian players of biosimilar drugs are Dr. Reddy’s Laboratory (DRL), Lupin, Zydus Cadila, Serum Institute of India, Biocon, Reliance Life Sciences, Wockhardt, Zenotech Laboratories and Intas.

I wrote on a related subject in this blog dated December 15, 2014 titled, “A Great News! But…Would This ‘Golden Goose’ Lay Golden Eggs?”

Conclusion:

Opportunities for biosimilar drugs are expected to expand significantly all over the world, basically driven by the need for affordable biologics and healthcare cost containment pressure in many countries.

As I had articulated before, unlike small molecule generics, unlocking the true potential of large molecule biosimilar drugs in a sustainable way would demand innovative, clear, razor sharp and highly focused business strategies across the value chain.

For faster growth in prescriptions, biosimilars would call for a hybrid marketing model of small molecule (branded) generics and large molecule original biologics. Ability to craft impactful value proposition and ensuring its effective delivery for each stakeholder, smart and innovative use of interactive and participative digital tools both for doctors’ and patients’ engagement, of course sans complexities, would decide the ultimate commercial fate for each of these types of products.

To effectively reap rich harvest from the new space thus being created, the challenges are also too many. The concerns expressed on biosimilars may also be genuine, but the regulators should take care of those before granting marketing approval to benefit the patients, in a meaningful way.

Overall key drivers and barriers for success with biosimilar drugs would remain almost the same, both for global and local players. However, carving out and thereafter expanding share in this market, sizably, won’t be a piece of cake for any company, understandably.

Quite naturally, the innovator companies for biologics would go all out to retain their turf as much as possible, despite the entry of cheaper biosimilars. This is expected to continue by reinforcing the belief of the physicians and the patients that biosimilars are not quite the same as the original biologic molecules.

Effective proactive measures need to be initiated, soon, by the regulators and all other stakeholders to spread the right message, protecting the patients’ interest. Otherwise, apprehension of the doctors on biosimilars in general, regarding safety, efficacy, substitution and interchangeability may persist for some time to come, negatively impacting faster and desirable prescription growth of these drugs all over the world, including India.

A Great News! But…Would This ‘Golden Goose’ Lay Golden Eggs?

Posted on by
Reply

On December 9, 2014, international media flashed across the world a great news item from the Indian pharma industry:

“The first biosimilar of the world’s top-selling medicine Humira (adalimumab) of AbbVie has been launched in India by Zydus Cadila.”

This exhilarating news has undoubtedly got frozen in time flagging a well-cherished moment of pride for the Indian pharmaceutical industry. Along side, taking note of many contemporary factors in this area, a lurking apprehension too does creep in. It raises an awkward and uncomfortable question – would this ‘Golden Goose” born out of a laudable ‘reverse engineering’ effort be able to lay ‘Golden Eggs’, signaling its global commercial success for the company?

In this article, I shall try to dwell on on this important issue.

In one my earlier blog posts of August 25, 2014 titled, “Scandalizing Biosimilar Drugs With Safety Concerns”, I discussed another related concern in this area.

Born a ‘Golden Goose’:

Just to recapitulate, the original product Humira (Adalimumab) of Abbvie, a fully human anti-TNF alpha monoclonal antibody was first globally approved for marketing in 2002. Since then Humira has emerged as the most preferred therapy to reduce the signs and symptoms of patients suffering from moderate to severe rheumatoid arthritis, moderate to severe polyarticular juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, moderate to severe Crohn’s disease and moderate to severe ulcerative colitis. However, Humira is not available in the Indian market, at present.

Zydus Cadila has announced that its biosimilar version of Humira (Adalimumab), has been approved by the Drug Controller General of India (DCGI) and will be marketed under the brand name ‘Exemptia’ for the treatment of autoimmune disorders as indicated for Humira.

As claimed by the company, ‘Exemptia’ is a ‘fingerprint match’ with the original drug Humira in terms of purity, safety and potency. Zydus Cadila has also stated that the novel non-infringing process for Adalimumab and a novel non-infringing formulation have been researched, developed and produced by scientists in its own Research Centre.

With this the world took note of the ‘Golden Goose’, born out of brilliant ‘Reverse Engineering’ in India. However, the apprehension of many continued to linger: Would this ‘Golden Goose’ be able to lay ‘Golden Eggs’?

The product and the price:

According to an estimate, over 12 million patients in India suffer from the above chronic conditions of autoimmune disorders, which progressively deteriorate and lead to lifelong pain and in some cases, even disability. To treat these indications, Exemptia is recommended as a 40 mg subcutaneous injection once every alternate week. Patients normally would have to take the treatment for six months.

Media reports indicate that ‘Exemptia’ of Zydus Cadila will be priced in India equivalent to US$ 200 a vial against Humira price in the United States of US$ 1,000. Initial overall reaction for this local price does not seem to be quite favorable for India.

The global market:

A recent report from Thomson Reuters indicates, as blockbuster drugs with sales turnover of around US$100 billion lose patent protection, the global biosimilars market is expected to grow around US$ 25 billion by the end of the decade.

According to a 2013 report of the credit rating agency Fitch, eight of the current 20 top-selling global pharmaceuticals are biologics that will face patent expiry by 2020.

EvaluatePharma reported that the current the anti-rheumatics market makes up the second largest treatment area by sales, with worldwide revenues of US$ 41.1 billion, closely behind the oncology therapy area, which registered sales of US$68 billion in 2012 with a high growth rate.

The report also states, despite biosimilar entry Anti-rheumatics segment is expected to record a Compound Annual Growth Rate (CAGR) of 4 percent with a turnover of around S$52.1 billion in 2018.

The local potential:

Over the last several years, China and India have been emerging as the promising destinations for international outsourcing of biopharmaceutical manufacturing. In the recent times, China and India are reportedly showing promises to become the industry’s top potential destinations for offshoring over the next five years, ahead of traditional bio manufacturing hubs in the US and Western Europe.

More than 40 biosimilar products are now available in the Indian market. Over 10 pharma players are competing in this area with around 15 epoetin, 8 G-CSF and 4 insulin “biosimilars”, besides a few others.

Although India has the second largest USFDA approved drug manufacturing plants next to the United States, none of the products manufactured in these facilities can possibly be considered as “true biosimilars”.

Humira expected to remain strong:

EvaluatePharma also forecasts that Humira of AbbVie would continue to remain the best selling drug of the world at least till 2018 with sales of US$12.8 billion, despite its US patent expiry in 2016.

Moreover, to succeed Humira that will go off patent between end 2016 and 2018 (Europe), AbbVie reportedly has seven new drugs in clinical development for Rheumatoid Arthritis. These patented new drugs could also significantly cannibalize the sales of Humira.

Physicians’ attitude towards biosimilars:

According to an October 2014 Report of IMS Institute from Europe’s perspective, within each country’s health system, physicians display a range of attitudes and behaviors that influence their prescribing of biosimilars.

IMS observed three broad segments of prescribers as follows:

  • Conservative prescribers: These doctors tend to be late adopters of new technologies, are more likely to follow published clinical treatment guidelines, and may not be aware of or educated on the availability of potential use of biosimilars.
  • Open-minded prescribers: This archetype includes physicians who tend to be the most responsive to new information about treatment options, particularly where experience and knowledge of biologics may be low and educational program can be effective in impacting usage.
  • Enterprising prescribers: This segment of prescribers is most likely to search out information from all sources, and be open to trying different options for patient care including biosimilars as well as innovative treatments.

In addition to these archetypes, the report states, physicians’ attitudes and prescribing behavior may also be influenced or determined by prescribing guidelines, if any, the use of prescribing incentives, as well as the use of promotional activities by either originator or biosimilar manufacturers.

The US biosimilar challenge:

According to reports, despite two pharma players filing biosimilar applications at the USFDA, there are still many issues to be sorted out in this space by the drug regulator of the country.

Though an interchangeable biosimilar in the United States still appears to be several years away, there are initiatives in some American states to restrict interchangeable biosimilar for substitution against the reference product.

Moreover, USFDA’s draft guidance on clinical pharmacology of May 2014 has invited strong adverse comments from the innovator companies, lobby groups and the industry associations.

However, just in the last week, both the innovator companies and biosimilar manufacturers have reportedly agreed to support state legislation that allows pharmacies to automatically substitute biosimilars for corresponding branded biologics. But pharmacies must give prescribers a heads up afterward “within a reasonable time.”

For biosimilars makers, it’s a big improvement on the alternative, as the biotech developers wanted to require pharmacists to check with doctors before making the switch.

That said, the USFDA is yet to determine exactly how to classify biosimilars and their “reference products” as interchangeable. This guidance for classification would be necessary for the above mentioned pharmacy switches. This guidance is important especially for the statutory language, which dictates that interchangeability is proven for “any given patient”. This could also be construed as requiring studies in all the approved indications for a brand name biologic, i.e. Humira has around five different indications.

Thus, the path ahead still remains challenging for the biosimilar players in the United States, and more so for the Indian Companies, as compared to other global pharma majors with deep pockets.

Several other Humira biosimilars under development too:

As indicated earlier, the US and Europe patents of Humira with worldwide sales of US$ 11.02 billion in 2013 would expire by end 2016 and 2018, respectively. Thus, the product has become among the most sought-after biosimilar target prototypes for many pharma and biotech companies across the world.

The global biotech major Amgen has already indicated that its ABP 501 biosimilar has shown comparable efficacy and safety to Humira (adalimumab) in a late-stage trial in patients with moderate-to-severe plaque psoriasis after treatment duration of 16 weeks. The product, reportedly, has also matched Humira in stimulating immune response in patients.

Experts believe, Amgen could be in a position to compete directly with Humira when it loses patent protection, if similar results are obtained in the second phase III trial.

Moreover, according to available reports, Boehringer Ingelheim, Sandoz (Novartis) and Coherus are also progressing well with the development of Humira biosimilars.

Zydus Cadila expects that in 2019 it would be ready to launch the biosimilar of Humira (Adalimumab) in the United States.

Marketing challenges for biosimilars:

Today, the global biosimilars market is indeed in a nascent stage, even for the Indian players.

For successful commercialization of biosimilars, I envisage, a well-crafted hybrid marketing-model of small molecule generics on the one hand and large molecule biologics of the originators’ on the other would be appropriate, in the years ahead.

In the early marketing phase, biosimilar marketers are expected to follow the same branding, communication and detailing strategies of the originators, which ultimately would transform into a generic matrix as more players chip in with the price competition intensifying.

Unlike small molecule generics, affordable price of a biosimilar would be just one of the many critical considerations for its commercial success in the biologics market.

Sustained efforts and initiatives to allay safety concerns with biosimilars among both the doctors and also the patients would be a dire necessity. Providing in-depth medical, technical and domain knowledge to the sales team should never be compromised, though these would require additional initial investments. Post marketing surveillance or pharmacovigilance for biosimilars must be ongoing, even in India. Here too, Indian players do not seem to be very strong, as yet.

Thus, unlike small molecule generics, marketing a large molecule biosimilar would require clear, razor sharp and focused strategies across the value chain to unlock its true potential. Crafting impactful value propositions, avoiding complexities, for each stakeholder, would decide the commercial fate of the product.

‘Made in India’ issue for pharma needs to be addressed expeditiously:

High credibility clinical trial data and manufacturing quality standards would also play a decisive role, especially for India made biosimilars.

This is mainly due to widespread reports of frequent USFDA allegations related to falsification and doctoring of manufacturing data in several manufacturing plants of India.

Ethical and quality issues for drugs made in India, such as these, assumed even greater dimension, as the regulators in France, Germany, Belgium and Luxembourg reportedly suspended marketing approval for 25 drugs over the genuineness of clinical trial data from India’s GVK Biosciences. This is yet another blow to ‘Made in India’ image for medicines, which has arrested the global attention, for all the wrong reasons, just the last week. 

Conclusion:

Considering all the above points, let me now try to make a fair personal guess on whether or not the ‘Golden Goose’ would be successful enough to lay ‘Golden Eggs’, as required by the company.

Firstly, in the Indian perspective, the key point that strikes me is the cost of a treatment course with ‘Exemptia’ per patient in the country. On a rough calculation, it comes around Rs. 1,50,000 per course/per patient. This appears rather high according to the income level of an average Indian.

However, Zydus Cadila expects sales between Rs.1 billion (US$16.16 million) and 2 billion for ‘Exemptia’ only from the Indian market.

I reckon, with relatively high per course treatment cost with Exemptia, it may be quite challenging for the company to achieve this goal in the domestic market.

Thus, the global success of this biosimilar brand would mainly depend on its degree of success in the United States and Europe, post patent expiry of Humira.

Going by the possible availability of other Humira biosimilars from manufacturers with robust global marketing muscle, skill sets, experience and other wherewithal, the path of global success for Exemptia of Zydus Cadila, if the company decides to fly solo, appears to be strewn with many odds.

I would now stick my neck out to zero in with specificity in this area, while envisaging the possible future scenario.

Considering the evolving macro scenario together with the commercial success requirements in this space, I reckon, despite presence of several possible competitors of Humira biosimilars, including one from Zydus Cadila, the biotech domain expertise of Amgen, fuelled by its marketing muscle, would in all probability make its ABP 501 biosimilar the toughest competitor to Humira after its patent expiry in the US and Europe…and then…why doesn’t it try to succeed in India too?

Does Patent Expiry Matter Less For Difficult To Copy Drugs?

Posted on by

“Patent expiry matters much less for difficult to copy drugs”.

Not so long ago, this is what many used to believe in the pharma industry. However, looking at the current trend involving the tech savvy generic players, it appears, gone are those days even for the home grown companies in India. As we witness today, a number of global generic players, including some from India, are overcoming the tough challenge of technological barrier of the original drugs with technology, boldly and squarely, and that too with reasonably good speed.

A global CEO felt quite the same:

Possibly encouraged by this commercial dogma, the Chief Executive of GlaxoSmithKline (GSK) Sir Andrew Witty reportedly felt in not too distant past that his company’s blockbuster drug Advair/Seretide, used for the treatment of asthma, would continue to remain a major product, despite losing US patent in end 2010. Witty thought so considering the intricate technology involved in making its high tech inhalation drug delivery system with exacting precision.

Technology based entry barrier:

Although, Advair/Seretide is a respiratory inhalation drug, it is not quite like a typical aerosol inhaler consisting of a pressurized canister filled with liquid medicine formulation. In such system, as the canister is compressed, the liquid inside comes out as a spray that is breathable in an amount as required for desirable clinical efficacy for the patients.

With the application of complex technology, Advair/Seretide was formulated not as a liquid, but as pre-determined fixed dose combination of powders that patients inhale into their respiratory tracts with a device called ‘Diskus’, which involves a complex and difficult to copy inhaler technology with a long patent life.

This precision technology was expected to create the requisite entry barrier for generic equivalents of this important medicine.

“Diskus” patent to continue:

It is important to note, though Advair/Seretide had gone off patent in end 2010, the patent protection for the “Diskus” device that dispenses the powder version of the fixed dose drugs combination, continues till 2016. For the inhaler device that dispenses the aerosol version of the same drugs, the patent remains valid until 2025.

New USFDA guidance:

Keeping these factors in mind, the USFDA in its latest guidance has clearly enunciated the characteristics that an inhaler should have, including a similar size and shape to Diskus. This new USFDA guidance for inhaled drugs, like Advair/Seretide, now requires only “relatively basic” preclinical tests and a short clinical trial.

Many believe that this new guidance is mainly to ensure that other generic devices also qualify for the GSK’s asthma drug combo, after its patent expiry.

Nevertheless a challenging task:

Despite this new USFDA guidance for inhaled drugs, some large generic manufacturers apprehended, even way back in 2010, that they doubt whether it will be possible for them to adequately replicate Advair/Seretide to meet the stringent “substitution” requirements of the USFDA on generics. This is exactly what Witty had envisaged earlier.

Almost two years after its patent expiry, in October 2012, the world’s largest generic drug maker Teva also announced that the company does not expect to see true substitutes for Advair/Seretide before 2018.

No immediate sales impact post-patent expiry:

As a result, in 2012, even a couple of years after its patent expiry, Advair/Seretide could successfully weather the impending storm, though GSK reported a lackluster overall business performance. The brand at that time was virtually immune to substitution threats from generic equivalents. The key reason being, as stated above, much unlike a patented chemical drug substance, the ‘Diskus’ system of the GSK inhaler is a hell of a task to copy by meeting the regulatory requirements of substitution.

In 2013, close to three years after its patent expiry, Advair/Seretide ranked fourth within the top 10 global best-selling drugs of that year, clocking annual revenue of US $8.25 billion.

The first competition:

In the midst of all these, the first generic equivalent of Advair/Serevent with a new inhalation device, carrying a name AirFluSal Forspiro from the Sandoz unit of Novartis, started warming up to obtain regulatory approval from several countries within the European Union (EU).

The product was first approved in Denmark on December, 2013 with subsequent marketing authorizations received in Germany, Sweden, Hungary, Romania, Bulgaria, and Norway.

The heat started being felt now:

The overall position of the brand started changing thereafter. According to published reports, sales trend of Advair/Seretide in Europe and other markets are on the decline in 2014. In Europe, the drop was around 3 percent and in the US around 19 percent in the last quarter, due to a combined impact of many factors.

According to Bloomberg, the sales of Advair/Seretide are expected to drop from US$8.25 billion in 2013 to US$5.9 billion in 2016 with the entry of generics.

A large and growing market to invest into:

According to the World Health Organization (WHO), in every 10 seconds, Chronic Obstructive Pulmonary Disease (COPD) that includes conditions such as chronic bronchitis and emphysema kills one person globally. It is expected to be the third leading cause of death worldwide by 2030.  However, though more number of people suffers from asthma globally, its mortality rate is still much less, WHO says.

Bloomberg estimates that COPD market, including asthma, is expected to reach over US$30 billion by 2018.

Cipla came next crossing the ‘technology hurdle’:

Though the leader in the global generic market – Teva, expressed its inability to introduce the generic version of Advair/Seretide before 2018, this month, the Indian pharma major Cipla introduced its version of the product in two European countries, just next to Novartis. Consequently, Cipla demonstrated its ability to overcome the technological hurdle of the product faster than most others and mastering the intricate NDDS technology in record time, with precision.

The Cipla product is named as ‘Serroflo’ in Germany and ‘Salmeterol/Fluticasone Cipla’ in Sweden. As reported in the media quoting Cipla Chairman Dr. Yusuf Hamied, the product has also been launched in Croatia. By now, Cipla has obtained regulatory approvals of this product in 10 countries in total, with an approval pending in the GSK’s own domestic turf, the United Kingdom (UK). Other country-wise launches in Europe would probably take place much before the end of 2014, according to Dr. Hamied.

The product is expected to be launched in the US in the next three to four year’s time, though one media report mentioned about its 2015 launch in that market. Dr. Hamied also said that his company is now planning its first-ever manufacturing plant in America, which might focus on producing HIV medicines.

On a conservative estimate, the market analysts expect Cipla to generate around US$50 million in sales from the EU markets by 2016 and around US$110 million by 2018, as the company gains increasing market access with not more than 4-5 generic competitors competing in this segment.

Be that as it may, getting regulatory approval for launch of a generic version of Advair/Seretide in the regulated markets, by itself, is a huge achievement of technological prowess that Cipla has demonstrated, yet again.

Not too many generic competition expected:

Because of high quality technological requirements to develop a replaceable generic version of the GSK product, not too much competition is expected in this segment.

Thus far, another global generic drug major Mylan is expected to file for a generic version of Advair/Seretide in the US by the third quarter of 2015 for a 2016 launch. Besides Cipla and Novartis, Mylan, Teva and Actavis are expected come out with the generic version of this drug.

Opportunities in ‘difficult to copy’ drugs:

According to a recent ‘RnR Market Research Report’, over 1,400 drugs with New Drug Delivery System (NDDS) have since been approved globally. This includes inhalation devices too.

The oral drugs contribute the largest share of the overall NDDS market with over 52 percent of the total pie. This segment is expected to attain a turnover of over US$90 billion by 2016 at a CAGR of 11 percent. The injectable new drug delivery market is expected to reach a turnover of over US $29billion by 2015, according to this report.

I have deliberated this subject in one of my earlier blog posts titled. “Moving Up The Generic Pharma Value Chain”.

Another high tech area – biosimilar drugs:

As the high priced biologic drugs of the innovator companies go off patent, large molecule biosimilar drugs, involving high technology, would emerge as another lucrative growth opportunity for the generic players having requisite wherewithal.

Recombinant vaccines, erythropoietin, recombinant insulin, monoclonal antibody, interferon alpha, granulocyte cell stimulating factor like products are now being manufactured by a number of domestic biotech companies. Some of the Indian companies that have already entered into the biosimilar segment are Dr. Reddy’s Laboratories (DRL), Lupin, Biocon, Panacea Biotech, Wockhardt, Glenmark, Emcure, Bharat Biotech, Serum Institute, Hetero, Intas and Reliance Life Sciences, besides others.

The ultimate objective of all these Indian companies is to get regulatory approval of their respective biosimilar products in the US and the EU either on their own or through collaborative initiatives.

Overall improvement in the quality of ANDA filings:

In the last few years, overall quality of ANDA filings of the domestic Indian pharma players has also improved significantly. Their regulatory filing schedules now include many complex molecules, injectibles, oral contraceptives, ophthalmic preparations, inhalers/other drug delivery systems and biosimilars, beside Para IV/FTFs. All these are now contributing a growing share in their new product initiatives for the regulated markets.

Conclusion:

In the largest pharma market of the world – the United States, global generic companies are increasingly facing cutthroat price competition with steep price erosion, registering mixed figures of business performance and growth.

However, a new trend is fast emerging. Even when global innovator companies are including increasing number of difficult to copy medicines in their product portfolio, some pharma players are reaping a rich harvest by moving up the value chain with the generic versions of those products, post patent expiry. These copycats offer much higher margin than non-differentiated generics.

Some Indian generic companies too have started focusing on building value added, difficult to manufacture, and technology intensive generic product portfolios in various therapy areas. DRL is reportedly all set to take its complex generic drug Fondaparinux sodium injection to Canada and two other emerging markets.

Those Indian pharma companies, which would be able to develop a robust product portfolio of complex generics and other differentiated formulations for the global market, would now be much better placed in positioning themselves significantly ahead of the rest, both in terms of top and the bottom line performance.

The myth, as epitomized in the good old saying, “Patent expiry matters less for difficult to copy drugs”, seems to be partly true in delaying entry of generics immediately after the end of the monopoly period, at least, for now. However, I reckon, this gap of delay would eventually get much reduced, if not eliminated altogether, as we move on. Armed with cutting edge technology Cipla has almost busted the myth, as it came close second to Novartis with the launch of a complex generic equivalent of Advair/Seretide in the EU and other markets.

Pharma majors of the country, such as, DRL, Cipla, Lupin and Biocon, to name a few, are taking great strides, setting examples for many others to emulate and excel in this area. The groundswell has already begun for a long haul global journey of the Indian pharma into the El Dorado of high tech generics fetching higher rewards.

Scandalizing Biosimilar Drugs With Safety Concerns

Posted on by
Reply

With the patent expiry of exorbitantly priced biologic medicines, introduction of biosimilar drugs are expected to improve their access to millions of patients across the world, saving billions of dollars in healthcare costs in the subsequent years. According to an article published in Forbes, it is estimated that the potential savings in the United States alone from just 11 biosimilar drugs over a period ranging from 2014 to 2024 could easily be U$250 billion.

However, the flip side of this much awaited development would make commensurate dent on the sales performance of original brand name biologics, now being marketed by the global pharma majors armed with patent monopoly rights.

Innovating hurdles to negate the impact:

Facing this stark reality, global innovators of biotech drugs allegedly want to fast germinate a strong apprehension in the minds of all concerned on the safety and replaceability of biosimilar drugs. Consequently, this would severely restrict the usage of this new class of products, sacrificing patients’ health interest.

To translate this grand plan into reality, garnering additional support from ten medical societies and a physicians’ group, the global players, which mostly hold various patents on biologics, reportedly urged the USFDA to require biosimilars to have distinct names from the original biologics, on the pretext that different names would make it easier for prescribers to distinguish between medicines that “may differ slightly” and also track adverse events and side effect reports that appear in patient records.

However, other stakeholders have negated this move, which is predominantly to make sure that no substitution of high priced original biologics takes place with the cheaper versions of equivalent biosimilars to save on drug costs.

Intense lobbying to push the envelope:

Interestingly, this intense lobbying initiative of big pharma to assign a distinct or different name for biosimilar drugs, if accepted by the USFDA, would provide a clear and cutting-edge commercial advantage to the concerned pharma and biotech majors, even much after their respective biologic drugs go off patent.

Thus, the above allegedly concerted move does not surprise many.

Mounting protests against industry move:

Biosimilar drug makers, on the other hand, have suggested to the USFDA to make biosimilars fall under the same International Non-Proprietary Name (INN) system, like all generic prescription drugs.  They believe that new names would create confusion and the physicians and pharmacists may face difficulties in ascertaining whether biosimilar drugs serve the same purpose with similar dosing and regimens.

The protest seems to have a snowballing effect. In July 2014, by a letter to the Commissioner Hamburg of USFDA, different groups representing pharmacy, labor unions, health insurance plans and others, have reportedly urged her not to go for different INNs for the original biologic and a biosimilar drug, for the same reason as cited above. The letter reinforces that the industry move, if accepted by the USFDA could increase the possibility of medication errors, besides adversely affecting the substitution required to bring down overall health care costs for high priced specialized biologics, thereby slowing down the uptake of biosimilars significantly.

Global pharma investors also raising voices in support of biosimilars:

Another similar and major development followed soon. A letter titled, “Investor Statement on Board Oversight of Biosimilar Issues”, written by a group of 19 institutional investors that manages about US$430 billion in assets, to the boards of several big pharma and biotech companies, flagged that some pharma majors have been scandalizing the safety concerns of biosimilar drugs. This is happening despite the fact that this class of drugs already has a well-established track record in Europe.

They emphasize that recent actions taken by some big pharma companies could raise concerns on the overall acceptance of biosimilar drugs, which would forestall any projected savings on that subject. They also reportedly expressed serious concern that shareholder interests could be adversely affected, if the pharma and biotech players pursue those policies that undermine corporate transparency and medical innovation.

The letter underscores, “Companies seeking to downplay the patient safety record of European biosimilars have also challenged the capacity of the FDA to promulgate rules and determine when biosimilars may be substituted for biologics.”

Among other points, the letter reiterates:

  • Though the important role of biologics in treating cancer, rheumatoid arthritis, anemia, multiple sclerosis and many other conditions is well recognized, the costs of these medicines are on an unsustainable trajectory, with some biologics costing as much 22 times more than other drugs. This critical issue seriously impedes patients’ access to biologics, as well as, acceptance by providers and insurance companies.
  • Biosimilars hold the promise of lowering costs of treating conditions for which biologics are indicated. At the same time, the recent adoption of a regulatory pathway to approval of biosimilars in the US market and the continued growth of biosimilars in the European Union, Japan, Canada, Australia and South Korea, pose a formidable business challenge for the companies that market patented biologic medicines.
  • Financial experts project that biosimilars too have the potential for significant market penetration and attractive returns on investments.
  • Assigning different INN would communicate to providers that the biosimilar is less effective, prompting them not to prescribe this class of medicines and making it difficult for the pharmacists to dispense too. Besides, different names could lead to prescribing errors.
  • In short, the boards of directors of the pharma and biotech majors were urged by these investors to use the following principles to guide their decision-making related to biosimilars:

-       Policy and educational information provided on biosimilars should be balanced, accurate and informed by the patient safety experience of biosimilars in the European Union and other biosimilar drug markets.

-       Lobbying expenditures for federal and state activities related to biosimilars should be fully disclosed and the boards should ensure that political activities are aligned with the interests of investors and other stakeholders.

-       Key information about any partnership or business deal related to biosimilars should be fully disclosed to investors, including information about the value, terms and duration of the deal.

The WHO proposal:

In this context it is worth recapitulating, the World Health Organization (WHO) that oversees the global INN system has held a number of meetings to resolve this issue. The WHO proposal suggests that the current system for choosing INNs to remain unchanged, but that a four-letter code would be attached at the end of every drug name. However, individual regulatory agencies in each country could choose whether to adopt such coding or not.

Let us wait to see what really pans out of this flexible WHO proposal on the subject.

Biosimilars go through stringent regulatory review:

It is important to note that the drug regulators carefully review biosimilars before giving marketing approval for any market, as these drugs must prove to be highly similar without any clinically meaningful differences from the original biologic molecules. The interchangeability between biosimilars and the original biologics must also be unquestionably demonstrated to be qualified for being substitutable at the pharmacy level without the need for intervention by a physician.

Thus, there does not seem to be any basis for different INN, other than to severely restrict competition from biosimilars.

12-year data exclusivity period for biologics – another hurdle created earlier:

Another barrier to early introduction of cheaper biosimilar drugs in the United States is the 12-year data exclusivity period for biologics.

On this issue GPhA – the generic drug makers’ group in the United States reportedly issued a statement, criticizing a paper of Biotechnology Industry Organization (BIO), saying:

“Market exclusivity acts as an absolute shield to their weak patents. Thus, from a practical perspective, extending market exclusivity beyond the Hatch-Waxman period would block the introduction of generic competition for almost 20 years, derailing any potential cost savings by Americans.”

The market potential of biosimilars:

A new report by Allied Market Research estimates that the global biosimilars market would reach US$35 billion by 2020 from the estimated US$1.3 billion in 2013. During the next four years, over 10 blockbuster biologic drugs clocking aggregated annual sales turnover of US $60 billion would go off patent in the United States and in Europe. Humira – a US$10 billion drug of Abbvie that loses patent protection in 2016 is at the top of list.

In tandem, facilitation of regulatory pathways of marketing approval for this class of drugs in many developed markets is expected to drive its growth momentum through greater market penetration and access.

Asia Pacific region is likely to emerge as the leader in the biosimilar drugs market, primarily due to heightened interest and activity of the local players. Collaboration between Mylan and Biocon to commercialize biosimilar version of trastuzumab of Roche in India and the approval of first biosimilar version of monoclonal antibody drug by Hospira in Europe are the encouraging indications.

High growth oncology and autoimmune disease areas are expected to attract more biosimilars developers, as many such biologics would go off patent during 2014 to 2019 period.

Monoclonal antibodies (mAbs) and erythropoietin would possibly be key to the growth drivers. Similarly, follitropins, interferons, and insulin biosimilars would emerge as high potential product segments over a period of time.

As we know, among the developed markets, Europe was the first to draft guidelines for approval of biosimilars in 2006. Consequently, the first biosimilars version of Granulocyte colony-stimulating factor (G-CSF) was introduced in the European Union under the regulatory guidance of European Medical Agency (EMA) in 2008. At present, there are three biosimilar versions of G-CSF available in the European market. Insulin biosimilars also show a good potential for the future.

India:

India is now well poised to encash on this opportunity, which I had deliberated in one of my earlier blog post titled, “Moving Up The Generic Pharma Value Chain”.

Current global usage of biosimilars:

Though regulatory pathways for biosimilar drugs are now in place in the United States, no biosimilar has yet been approved there. However, the US drug regulator has for the first time accepted an application for the approval of a biosimilar version of Neupogen (Filgrastim) of Amgen, which treats patients with low white blood cell counts. Sandoz has already been selling the biosimilar version of this drug in more than 40 countries outside the US.

According to the research organization ‘Pharmaceutical Product Development’, as on March 2013, at least 11 countries and the European Union (EU) approve, regulate and allow clinical trials of biosimilars. As of February 2012, the EU has approved at least 14 biosimilar medicines. The following table shows these countries by region:

Region

Countries
North America Canada
Europe E.U. (including U.K.)
Asia and Pacific China, India, Singapore, South Korea, Taiwan
Central and South America Argentina, Brazil, Mexico
Eastern Europe Russia, Turkey

Source: Pharmaceutical Product Development

Conclusion:

With the opening up of the United States for biosimilar drugs, the entire product class is expected to be catapulted to a high growth trajectory, provided of course no more allegedly concerted attempts are made to create regulatory hurdles on its path, as we move on. This is mainly because around 46 percent of the world biologic market as on 2010 was in the United States.

However, intense lobbying and power play against biosimilar or interchangeable biologics, allegedly sponsored by the big pharma, are acting as a barrier to this much awaited development solely to benefit the patients. Such activities also undermine attractiveness of investing in safer and more affordable interchangeable biologics.

It is indeed intriguing that all these are happening, despite the fact that the regulatory approval standards for biosimilars are very stringent, as each of these drugs:

  • Must be highly similar to the reference product
  • Cannot have clinically meaningful differences from the original ones
  • Must perform the same in any given patient
  • Would have the same risk associated with switching as the reference product

Thus, scandalizing biosimilar drugs by raising self-serving ‘safety concerns’ in an orchestrated manner, just to extend product life cycles of original biologics even beyond patent expiries, is indeed a very unfortunate development. In this process, the vested interests are creating a great commercial uncertainty for this new class of medicines in the global scenario.

Be that as it may, all these seemingly well synchronized moves against biosimilars, solely to protect business interest, pooh-poohing patients’ health interests, have once again caste a dark shadow on not so enviable image of the big pharma…without even an iota of doubt.

Just Born A Pharma Goliath: Would India Be Impacted?

Posted on by
Reply

Just born a potential pharma Goliath, as Actavis – the Dublin-based one of the largest global generic drug makers, in its biggest ever purchase, acquires New York based R&D based pharma major – Forest Laboratories, for a whopping US$ 25 billion.

It is worth noting that as on date Actavis has grown mainly through Mergers and Acquisition (M&A) route. In 2012, the company took over American generic drug major Watson Pharma for €4.5 bn and then Ireland’s Warner Chilcott, marketing patented drugs for gastrointestinal and urological conditions, for US $8.5 bn. Post buy out of Forest Laboratories, Actavis would have annual sales turnover of US$15 bn.

So far, mostly R&D based Pharma players acquired generic drug makers:

This acquisition is interesting. The reason being, since the last few years, mostly research based global pharmaceutical companies are taking over generic pharma players in the emerging markets with a reasonable speed. To cite a few examples:

In June, 2010, British drug major GlaxoSmithKline (GSK) announced acquisition of ‘Phoenix’, a leading Argentine pharmaceutical company focused on the development, manufacturing and marketing of branded generic products, for a cash consideration of around US $253 million. With this acquisition, GSK planned to accelerate its business growth in Argentina and the Latin American region.

Similarly, Paris based Sanofi with the acquisition of Zentiva, became an important player in the European generic drug market. Zentiva, is also a leading generic player in the Czech, Turkish, Romanian, Polish, Slovak and Russian markets, besides the Central and Eastern European region. In addition to Zentiva, in the same year 2009, Sanofi also acquired other two important generic players, Medley in Brazil and Kendrick in Mexico.

In February 2014, the German Drug major Bayer reportedly announced that it would buy Dihon Pharmaceutical Group Co of China, expanding the German company’s footprint in a key growth country. Dihon’s products are also sold in Nigeria, Vietnam, Myanmar and Cambodia. Privately held Dihon specializes in ‘Over-The-Counter (OTC)’ and herbal ‘Traditional Chinese Medicine (TCM)’ products.

Back home, MNCs acquired the following generic companies from 2006 to 2011:

Year Indian Companies Multinational Companies

Value ($Mn)

 Type of Deal
2006 Matrix Labs Mylan 736 Acquisition
2008 Ranbaxy Labs Daiichi Sankyo 4,600 Acquisition
Dabur Pharma Fresenius Kabi 219 Acquisition
2009 Shantha Biotech Sanofi-aventis 783 Acquisition
2010 Orchid Chemicals Hospira 400 Acquisition
Piramal Healthcare Abbott 3,720 Acquisition
Paras Pharma Reckitt Benckiser 726 Acquisition
2011 Universal Medicare Sanofi 110 Acquisition
2013 Mylan Agila Specialities 1750 Acquisition

Key drivers for generic acquisition:

From 2012 to 2015 patented drugs with a combined turnover of US$ 183 billion have already faced or would face intense generic competition resulting in, as high as, around 90 percent price erosion for those products. It is not just patent expirations that are exerting pressure on innovator companies. Added to this, a relatively weak R&D pipeline and increasing focus of various governments to reduce healthcare costs, have forced many research based global pharma players to imbibe the inorganic growth strategy in the generic space to quickly grab a sizable share of this large and fast growing market, especially in the emerging economies of the world.

Actavis acquisition is different:

In the above light Actavis’s acquisition of Forest Laboratories is quite different. Here, instead of a predominantly research-based company’s acquiring a generic player, a basically generic drug major has bought a research based global pharmaceutical player.

Interestingly, Forest Laboratories follows a unique R&D model. It is focused on, instead of discovering on its own, identifying strong medically relevant product candidates and guiding them through the complex development lifecycle, from proof-of-concept through post-marketing.

Strong global portfolio of both generic and patented drugs:

Post buy out, Actavis would have a strong combo-portfolio of generic drugs together with a relatively robust line-up of a diverse range of patented products, spanning across therapy areas such as Anti-Infective, Respiratory, Cardiovascular, Central Nervous System, Gastrointestinal, Obstetrics and Pain Management and that too not just in the emerging markets, but globally, unlike many others.

In addition, acquisition of Forest Laboratories would also provide Actavis access to former’s large US sales teams, transforming the merged entity a formidable force to reckon with in the topmost pharmaceutical market of the world, besides many others.

An intriguing recent decision:

That said, it is interesting to note that in January 2014, Actavis, then the second-biggest generic drug maker by market capitalization, announced that it would quit China as “It is not a business friendly environment… China is just too risky”. This is indeed intriguing, because by 2015, China’s generic market is expected to be close to US$ 82 billion.

Be that as it may, post acquisition Actavis would be in a position to offer all its customers in all the markets of the world a rainbow of products from patented to generics, carving out a critical strategic advantage for itself in the global pharmaceutical market.

Impact in India:

The question now boils down to what would be the impact of the just born Goliath on the domestic pharmaceutical industry in India.

Differentiated generic business:

The generic drugs market is usually classified as simple generics, super-generics and biosimilars. To differentiate, by adding value in the generic medicines, many domestic players are gradually entering into the ‘Super Generic’ and ‘biosimilar’ category of drugs. For example, Dr Reddy’s Laboratories has reportedly chosen to go for a difficult to copy drug formulation with its blood-thinner Fondaparinux. Sun Pharma, on the other hand, is focusing on innovative delivery platforms for its ophthalmic drugs and oral contraceptives. Cadila is looking at newer drug delivery modes for its painkiller Diclofenac. So is Lupin in other areas. In the biosimilar arena, Biocon has already developed Trastuzumab formulation of Roche. Moreover, the biosimilar business of Dr Reddy’s Laboratories continues with its impressive growth trend, besides many other Indian players in the same fray.

Simultaneously, India is improving its effectiveness in ‘Contract Research and Manufacturing Services (CRAMS) space. As we have recently witnessed in India the alliances between Merck & Co and Cipla and earlier with Sun Pharma. Even prior to that, collaborative agreements of Pfizer with Aurobindo Pharma; GSK with Dr Reddy’s Laboratories; Abbott India with Cadila and many more, would vindicate this point.

Merck Serono of Germany also announced a partnership to co-develop a portfolio of biosimilar compounds in oncology, primarily focused on monoclonal antibodies (MAbs) with Dr. Reddy’s Laboratories. The partnership covers co-development, manufacturing and commercialization of the compounds around the globe, with some specific country exceptions. Mylan has also signed similar agreement with Biocon.

Glenmark Pharma has chosen yet another route, by entering into collaboration with Forest Laboratories (now Actavis) in 2013, for the development of a novel mPGES-1 inhibitor for chronic inflammatory conditions, including pain management.

Advantage India, provided…

Global generic drugs market would get its next booster dose with reportedly around 46 drugs going off patent opening a market of another US$ 66 billion from monopolistic to intense generic competition in 2015.

Details of ANDA status from the US-FDA source, as I indicated in my earlier blog post, probably indicate that several Indian players have already started moving in that direction at a brisk pace, keeping their eyes well fixed on the crystal ball. Over 30 percent of Abbreviated New Drug Applications (ANDAs) and around half of the total Drug Master Filings (DMF) now come from the Indian Companies. In 2013 alone, the US-FDA granted 154 ANDAs and 38 tentative ANDAs to the Indian companies.

Despite all these, a serious apprehension does creep in, which finds its root in much-publicized fraudulent behavior of a few large Indian drug manufacturers, seriously compromising with the cGMP standards of some high profile global drug regulators. This challenge has to be overcome, sooner, to reap rich harvest out of the emerging global opportunities in the space of generic drugs.

Conclusion: 

Geographically, North America is the largest consumer of generic drugs followed by Europe and Japan. However, the highest growth of the generic drugs market is observed in the Asia-Pacific region. Besides Actavis, some of the major generic drugs manufacturers of the world are Mylan, Apotex, Hospira, Par Pharmaceutical., Sandoz International and Teva Pharmaceutical.

From India, Ranbaxy Laboratories (before the recent fiasco), Dr. Reddy’s Laboratories, Lupin and Sun Pharma, besides many others, are competing quite well in the global generic drugs market with success.

Though Actavis has its manufacturing operations in India with its registered office located in Mumbai, the company is not yet engaged in serious local marketing operations in the country. In 2006 as Watson Pharma Pvt Ltd., the company acquired Sekhsaria Chemicals in a move to push forward its generic drug agenda globally. In 2005, it acquired a manufacturing facility in Goa from Dr. Reddy’s Laboratories to produce solid dosage generic drugs for the US market.

Taking all these into considerations, if much deliberated cGMP issues with the foreign drug regulators are resolved sooner, Actavis is not expected to make any major difference for Indian pharma players either in the domestic market or for that matter globally, any time soon.

Thus Indian pharma players are unlikely to be adversely impacted with the emergence of this new potential Goliath in the global pharmaceutical landscape.

‘Herceptin Biosimilars’ Seriously Questioned

Posted on by
Reply

The news struck as an anticlimax, close on the heels of high decibel product launch of ‘Herceptin Biosimilars’ in India, being hyped as the first in the world, bringing much needed relief to many diagnosed breast cancer patients for their economical pricing.

At the same time, this legal challenge has now come as an acid test for the regulator to prove that ‘Caesar’s wife must be above suspicion’ for any new drug approval and especially if it is a complex biosimilar used for the treatment of patients suffering from dreaded diseases, such as, breast cancer.

It’s not patent this time:

Interestingly, this is not a patent infringement case, as Roche has reportedly given-up its patent on Trastuzumab (Herceptin) in India last year.

Alleged violations: 

The above media report highlights, in Delhi High Court Roche has sued Biocon of India and its US based generic partner – Mylan along with the Drug Controller General of India (DCGI) related to launch of ‘Herceptin Biosimilar’ versions in India.

The allegation against Biocon and Mylan is that their recently launched drugs are being misrepresented as ‘biosimilar Trastuzumab’ or ‘biosimilar version of Herceptin’ without following the due process in accordance with the ‘Guidelines on Similar Biologics‘, necessary for getting approvals of such drugs in India.

‘Caesar’s wife’ under suspicion too:

The DCGI has also been sued by Roche for giving permission for launch of this product allegedly not in conformance with the above biosimilar guidelines, which were put in place effective August 15, 2012.

Roche reportedly argued that the above guidelines on similar biologics laid down a detailed and structured process for comparison of biosimilar with the original product and all the applications for manufacturing and marketing authorization of biosimilars are necessarily required to follow that prescribed pathway before obtaining marketing approval from the DCGI. Roche has also stated that there is no public record available, in the clinical trial registry India (CTRI) or elsewhere to show that these two players actually conducted phase-I or II clinical trials for the drug.

According to report Roche claims that DCGI has approved the “protocol and design study for testing” of Biocon related to the proposed drug just before the above regulatory guidelines were made effective, predominantly for patients’ health and safety reasons.

Interim restrain of the Delhi High Court:

In response to Roche’s appeal, the Delhi High Court has reportedly restrained Mylan and Biocon from “relying upon” or “referring to Herceptin” or any data relating to it for selling or promoting their respective brands Canmab (Biocon) and Hertaz (Mylan) till the next hearing.

The relevance of ‘Guidelines on Similar Biologics’:

The ‘Guidelines on Similar Biologics’ clearly articulated:

“Since there are several biosimilar drugs under development in India, it is of critical importance to publish a clear regulatory pathway outlining the requirements to ensure comparable safety, efficacy and quality of a similar biologic to an authorized reference biologic.”

Thus for patients’ health and safety interest the above regulatory pathway must be followed, the way these have been prescribed without any scope of cutting corners. This is even more important when so important pharmacovigilance system is almost non-functional in India.

Attempts to dilute the above guidelines from some quarters:

It was earlier reported that strong representations were made to the drug regulator in writing by powerful domestic players in this area urging to dilute the above ‘Guidelines’, otherwise it will be difficult for them to compete with the pharma MNCs.

This argument is ridiculous by any standard and smacks of putting commercial considerations above patients’ health interest.

The key issue:

As I see it, four quick questions that float at the top of my mind are as follows:

  • If the ‘Guidelines on Similar Biologics’ have not been followed either by the applicants or by the DCGI, how would one establish beyond an iota of doubt that these drugs are biosimilar to Trastuzumab, if not ‘Biosimilar to Herceptin’?
  • If these drugs are not proven biosimilar to Trastuzumab, as specified in the ‘Guidelines on Similar Biologics’, how can one use Trastuzumab data for their marketing approvals and the DCGI granting the same?
  • If these drugs were not biosimilars to Trastuzumab, would these be as effective, reliable and safe as Herceptin in the treatment of breast cancer?
  • Further, how are references related to Herceptin being used to promote these drugs both pre and post market launch?

Conclusion:

I guess, predominantly commercial considerations prompted Roche to sue Biocon, Mylan and also the DCGI on ‘Trastuzumab biosimilars’, launched recently in India.

Be that as it may, for the interest of so many diagnosed breast cancer patients in the country, there is crying need for the facts to come out in the open, once and for all. Are these drugs truly Trastuzumab biosimilars with comparable safety, efficacy, quality and reliability of Herceptin?

If the answer comes as yes, there would be a huge sigh of relief from all corners inviting millions of kudos to Biocon and Mylan.

However, if by any chance, the allegations are proved right, I do not have an iota of doubt that the honorable Delhi High Court would ferret out the truth, unmask the perpetrators and give them exemplary punishments for playing with patients’ lives.

Herceptin Biosimilar Expands Drug Access to Breast Cancer Patients in India

Posted on by

Come February 2014, much to the relief of more than 145,000 patients diagnosed with breast cancer in India, Herceptin of Roche, a critical drug for the treatment of the dreaded disease, will face competition, for the first time, from a less expensive biosimilar equivalent. The product named Canmab developed together with Mylan by Biocon has been priced 25 percent less than Herceptin.

Patient access issue for newer cancer therapy:

Herceptin has been a very critical drug, though equally expensive, for breast cancer patients globally.

Mainly because of its unusual high price, the product created an access barrier to majority of patients in India. Arising out of complexity of the problem faced by the cancer patients, hugely compounded by the affordability issue, on January 12, 2013, it was first reported that in a move that is intended to benefit thousands of cancer patients, Indian Government has started the process of issuing Compulsory Licenses (CL) for three commonly used anti-cancer drugs: 

-       Trastuzumab (or Herceptin, used for breast cancer),

-       Ixabepilone (used for chemotherapy)

-       Dasatinib (used to treat leukemia).

For a month’s treatment drugs like, Trastuzumab, Ixabepilone and Dasatinib reportedly cost on an average of US$ 3,000 – 4,500 or Rs 1.64 – 2.45 lakh for each patient in India.

Pricing issue needs a systemic resolution: 

While there is no single or only right way to arrive at the price of a patent protected medicine, how much the pharmaceutical manufacturers will charge for such drugs still remains an important, yet complex and difficult issue to resolve, both locally and globally. Even in the developed nations, where an appropriate healthcare infrastructure is already in place, this issue comes up too often mainly during price negotiation for reimbursed drugs. 

A paper titled, “Pharmaceutical Price Controls in OECD Countries”, published by the U.S. Department of Commerce, after examining the drug price regulatory systems of 11 OECD countries, concluded that all of them enforce some form of price control to limit spending on pharmaceuticals. The report also indicated that the reimbursement prices in these countries are often treated as de facto market price.

Though there is no such system currently prevailing in India, the Government is mulling to put in place a similar mechanism for patented medicines, as captured in the National Pharmaceutical Pricing Policy (NPPP) 2012.

Further, some OECD governments regularly cut prices of even those drugs, which are already in the market. The value of health outcomes and pharmacoeconomics analysis is gaining increasing importance for drug price negotiations/control by the healthcare regulators even in various developed markets of the world to ensure responsible pricing of IPR protected medicines. For various reasons, no such process is followed either for such product pricing in India, as on date.

Roche changed Herceptin strategy for India:

To effectively address the challenge of pricing of patented medicines in India, Roche reportedly entered into a ‘never-before’ technology transfer and manufacturing contract for biologics with a local Indian company – Emcure Pharma for its two widely acclaimed ‘Monoclonal Antibodies’ anti-cancer drugs – Herceptin and MabThera.

Consequently, Roche introduced its ‘made in India’ brand Herclon (Herceptin) with a much-reduced maximum retail price of about Rs. 75,000 for a 440 mg vial and started co-marketing the product with Emcure Pharma in India.

Although Herceptin patent remains valid in the United States (US) until 2018, Roche decided to discontinue its patent rights for Herceptin in India in 2013.

The pharma major reportedly lost this patent earlier in Europe. This vindicates the views of many experts that Herceptin patent was weak, as it would probably not be able to clear the litmus test of a stringent scrutiny under the Patent Acts of India. The report, therefore, argues that core reason for withdrawal of Herceptin patent in India by Roche cannot be attributed, even remotely, to the ‘weak IP ecosystem’ in India.

Biocon Pricing:

According to reports Biocon’s Canmab, the biosimilar version of Herceptin, will be available in 440 mg vial with a maximum retail price of Rs. 57,500 and also in 150 mg vial at Rs. 19,500.

Lower price would lead to greater patient access – Roche argued earlier:

It was reported, when Roche switched over to Herclon with around 30 percent discounted price from very high price Herceptin, access to the drug improved. In fact, that was the logic cited by Roche for the launch of Herclon in India at that time. 

Just to recapitulate, media reports indicated at that time that Roche intends to offer to Indian patients significantly cheaper, local branded version of Herceptin sooner. The same news item also quoted Roche spokesperson from Basel, Switzerland commenting as follows:

“The scope is to enable access for a large majority of patients who currently pay out of pocket as well as to partner with the government to enable increased access to our products for people in need”.

Conclusion:

It is beyond doubt that even with significantly lower price, Canmab would not be able to guarantee 100 percent access to the drug for all breast cancer patients in the country.

However, applying the same logic of Roche, as mentioned above, with further 25 percent price discount for Canmab by Biocon, the access to this drug should expand significantly for over 145,000 diagnosed breast cancer patients in India even, for an argument’s sake, all other factors, including inadequate number diagnostic facilities etc. remain the same. Isn’t that better?
