Will ‘Patent Thicket’ Delay Biosimilar Drug Entry in India?

Do pharma and biotech investors encourage companies indulging in ‘patent thicket?’ This question recently grabbed media headlines. On April 02, 2019, one such report brought out: AbbVie investors are calling for the Chair-CEO power split, flagging the CEO’s USD 4 million bonus payout, fueled by the company’s Humira ‘patent thicket’ strategy related aggressive price hikes. It prolonged the brand’s market monopoly, blocking entries of its cheaper biosimilar equivalents.

I have discussed some related issues in this blog, previously. As the issue is gaining relevance also in the Indian context, this article will deliberate the ill-effects of ‘patent thicket’ on patient health-interest. The sole beneficiaries for the creation of this self-serving labyrinth are the manufacturers of high-priced patented drugs, as reported above. Before I proceed further, let me recapitulate what exactly is a ‘patent thicket.’

‘Patent Thicket’:

The dictionary definition of patent thicket is: ‘A group of patents in a field of technology which collectively impede a party from commercializing its own patents or products in that field.’In the current context, it means a dense web of overlapping patent rights that restrict a generic or a biosimilar drug maker from commercializing its cheaper equivalents post expiry of the original patent.

This scenario has been well-captured by the above media report, which states: “AbbVie leadership has also been accused of creating a ‘patent thicket’ in its battle to stave off biosimilar competitors to Humira.” Boehringer Ingelheim is among the few still fighting AbbVie’s ‘patent thicket’ hoping to launch its Humira biosimilar - Cyltezo, even after receiving US-FDA approval on August 29, 2017. ‘Top biosimilar makers, including Novartis’ Sandoz unit and Mylan, have settled their own Humira patent fights with deals that put off launches until 2023,’ the report indicated.

In its favor: AbbVie says, Cyltezo infringes about 70 patents the company currently holds for Humira. Whereas, ‘Boehringer’s lawyers say AbbVie’s copious patents overlapped in an attempt to exclude competitors from the market.’ Notably, in March this year, New York’s UFCW Local 1500 Welfare Fund, reportedly, also accused AbbVie of using overlapping patents to exclude biosimilars.

‘Patent thicket’ – a way of ‘evergreening’ beyond 20 years patent term:

Much concern is being raised about various ploys of especially by the drug MNC and their lobby groups – directly or under a façade, to delay entry of cheaper generic drugs for greater patient access. Mostly the following two ways are followed for patent ‘evergreening’ beyond the term of 20 years:

  • ‘Incremental innovation’ of the existing patented drugs through molecular manipulation, with its clinical performance and safety profile remaining similar to the original one. As the cost benefits of such drugs are not shared with patients, cannibalizing the sales of the older molecular version with the newer one highlighting its newness, the sales revenue can be protected. With this approach, coupled with marketing muscle power with deep-pocket the impact of generic entry of the older version can almost be made redundant. For example: Omeprazole was first marketed in 1989 by AstraZeneca, under the brand name Losec (later changed to Prilosec at the behest of the US-FDA). When Prilosec’s US patent expired in April 2001, AstraZeneca introduced esomeprazole (Nexium) as a patented replacement drug. Both are nearly identical in their clinical efficacy and safety.
  • ‘Patent thicket’ is yet another tool for ‘evergreening’, delaying launch of similar drugs, or resorting to ‘pay for delay’ sort of deals. As another recent report reiterates, AbbVie’s ‘patent thicket’ for Humira, has deterred other potential challengers, such as Amgen, Samsung Bioepis and most recently Mylan, each of which struck settlements with AbbVie to delay their biosimilar challenges in the United States.

Goes against patients’ health interest:

On May 09, 2018, the Biosimilars Council reported, just as generic medicines saved Americans USD 1.67 trillion in the last decade, biosimilars are poised to do the same – ‘if they aren’t thwarted by delaying tactics instituted by some pharmaceutical companies.’ Echoing similar concern, the outgoing US-FDA Commissioner Scott Gottlieb also, reportedly said, ‘some drugmakers are using unacceptable tactics such as litigation and rebate schemes to stall the entry of cheaper copies.’

‘Of the nine biosimilars the FDA has approved to date, only three have made it into the hands of patients – an alarmingly small number. Patients can’t access the six others due to barriers thrown in their way by pharmaceutical companies that want to protect their monopolies and keep prices high,’ highlights the Biosimilars Council report. Net sufferer of this self-serving ‘patent thicket’ strategy of pharma and biotech players to extend product patents beyond 20 years, are those patients who need these drugs the most – to save their lives.

Despite law, patent ‘evergreening’ still not uncommon in India:

With section (3d) on the Indian Patents Act 2005 in place, the country is expected to protect itself from patent ‘evergreening’ through ‘incremental innovation.’ This section articulates:“For the purposes of this clause, salts, esters, ethers, polymorphs, metabolites, pure form, particle size, isomers, mixtures of isomers, complexes, combinations and other derivatives of known substance shall be considered to be the same substance, unless they differ significantly in properties with regard to efficacy.”

On this ground, Indian Patent Office (IPO) rejected Novartis’ drug Glivec (imatinib mesylate) patent application, which was ultimately upheld by the Supreme Court in 2013. Nevertheless, a study report of April 30, 2018 emphasized: ‘Though the law with regard to anti-evergreening, upheld and clarified by Indian courts, remains on the books, its application by the IPO has been far from satisfactory.’

The esteemed author of the report, after analyzing about 2,300 drug patents, granted between 2009 and 2016 concluded that evergreening practices may be rampant in India. The report pointed out, ‘the IPO could be operating with an error rate as high as 72 percent for secondary patents, despite provisions to keep them in check.’

Are these IPO’s mistakes, or due to external pressure?

As the paper, published in the January 2016 edition of the Journal of Intellectual Property Rights (JIPR) said,‘The multi-national pharma companies (MNCs) and the US-India Business Council (USIBC) have suggested in their report for elimination of Section 3 (d) so that drug patents can be granted in India for incremental improvement and modification. As per US 301 report, India is listed among countries with inadequate IP regime.’ Keeping all these aspects into consideration, the article expressed some key concerns pertaining to the impact of Section 3 (d) with special emphasis on its interpretation. Does it mean any possibility of wilting under such extraneous and high impact pressure?

A fresh pressure from drug MNC on the DCGI:

Since long drug MNCs have been attempting to delay the entry of even those generics, which are fully compliant with the Indian Patent Law 2005. One such effort was their demand for ‘patent linkage’ with the marketing approval of new generic drugs. However, it could not pass through legal scrutiny – first by the Delhi High Court in the Bayer Cipla case in 2010, and then by the Supreme Court – on the same case. The Court, reportedly, ‘noted the Indian patent system was distinct from the drug regulatory system with no linkage between them and so Bayer can’t prevent DCGI from granting marketing approval to generic versions of patented drugs.’

According to another recent media report of April 04, 2019, in a fresh endeavor ‘to delay launch of low priced generic medicine, multinational drug makers have asked the government to create a registry providing information about all drug applications pending manufacturing and marketing approval. The proposal, which is still pending with the Department of Pharmaceuticals (DoP), if accepted, could involve the generic players into expensive and time-consuming litigations, delaying early market entry of the cheaper generic or biosimilar equivalents.

To date, the health ministry has opposed the proposal, as it will be “unfair to local drug manufacturers to disclose their product strategy” and also has “the potential to substantially increase health care costs for the public.” The government further argued, “such information about product applications filed for approval are not disclosed anywhere in the world.”

India encourages new drug innovation, but not at any cost:

Despite shrill and disparaging comments of MNC lobbyists and the strong vested interests, that India’s Patent Law 2005, doesn’t encourage innovation, many independent international experts do praise the same for the following reasons:

  • Does encourage new drug innovation
  • Does extend product exclusivity for twenty years
  • Strikes a right balance with patients’ health interest
  • Indian judicial system deals with patient infringements and disputes, just as any other developed countries
  • Even 14 years after the enactment of patent laws, just one compulsory license has been granted, which is much less than other countries, including the United States.

What India doesn’t legally allow is, unfettered profit making through ‘evergreening of drug patents’ – at the cost of millions of patients-lives. Nonetheless, powered by deep pockets, the pharma and biotech players are unlikely to cease from this practice, anytime soon. Only patient-awareness, and stringent counter-legal measures can contain this unfair game of drug monopoly practices – in the name of ‘encouraging innovation’.

Conclusion:

The article titled, ‘Over patented, overpriced: How Excessive Pharmaceutical Patenting is Extending Monopolies and Driving up Drug Prices’ revealed:“Top grossing drugs have on average 125 patent applications, which are filed with a strategic intent to extend the commercial monopolies far beyond the intended twenty years of protection.” It also quoted American President Donald Trump as saying, “Our patent system will reward innovation, but it will not be used as a shield to protect unfair monopolies.”

Coming back to ‘patent thicket’ and the same classic case, another report of March 20, 2019 indicated, a new class action lawsuit filed by New York’s largest grocery union has accused AbbVie of violating antitrust and consumer protection laws, which AbbVie has defended by saying that its patent strategy for Humira has protected the investments that are necessary to “advance healthcare.”

Pharma and biotech companies’ maintaining patent monopolies far beyond twenty years has significant consequences on India’s healthcare system. Only patent lawyers and experts can possibly answer whether or not the Indian Patent Law 2005 can effectively deal with the practice of ‘evergreening’ with patent thicket. Intriguingly, taking a cue from recent developments, it seems many pharma and biotech investors too, deem ‘patent thicket’ rather distracting for longer-term undiluted focus on new product development, and sustainable investors’ return.

That apart, the question also comes, whether just as ‘antitrust and consumer protection laws’ in the US, the Competition Law of India will be able to do contain such unfair practices? Otherwise, with MNC lobbyists’ renewed activities in this area, ‘patent thicket’, especially for expensive biologic drugs, will delay market-entry of their cheaper biosimilar versions in India, as well, just as what is happening in the developed nations.

Patent Expiry No Longer End of The Road

Who says that the phenomenal success of blockbuster drugs is mostly eaten away by  ‘look-alikes’ of the same, immediately after respective patent expiry? It doesn’t seem to be so any longer, not anymore! Several examples will vindicate this emerging trend. However, I shall quote just a few of these from the published reports.

In 2016, the patent of AbbVie’s Humira (Adalimumab), indicated in the treatment of autoimmune diseases and moderate to severely active rheumatoid arthritis, expired in the United States (US). It will also expire in Europe by 2018. This event was expected to create significant opportunities for lower priced Adalimumab biosimilars in the US market, increasing the product access to many more patients at affordable prices. Just as it happens with patent expiry of small molecule blockbuster drugs. One of the classic examples of which, is a sharp decline in sales turnover and profit from Pfizer’s Lipitor (Atorvastatin), as its patent expired on November 30, 2011.

However, Humira topped the prescription-drug list of 2016 with an annual growth of 15 percent, accounting for USD 16 billion sales, globally. More interestingly, according to a recent report of EvaluatePharma, AbbVie’s Humira will continue to retain its top most ranking in 2020 with expected sales of USD 13.9 billion. Nevertheless, possible threat from biosimilars has slightly slowed down its growth. Although, there are many other similar examples, I would quote just three more of these to illustrate the point, as follows:

  • Rituxan (Rituximab, MabThera) indicated in the treatment of cancer and co-marketed by Biogen and Roche, went off-patent in 2015. However, in 2016, the product held 4th position in the prescription drug market with a revenue growth of nearly 3 percent. Even five years after its patent expiry, Rituxan is still expected to occupy the 17th rank with an estimated turnover of over USD 5 billion in 2020, according to the EvaluatePharma report.
  • Remicade (Infliximab) indicated for autoimmune diseases and manufactured by J&J and Merck, lost market exclusivity in 2015. But, in 2016 it still held 5th place in the global ranking. Five years after it goes off patent, Remicade is expected to feature in the 6th rank in 2020, with an estimated turnover of over USD 6.5 billion, according to the same report as above.
  • The US product patent for Lantus – a long-acting human insulin analog manufactured by Sanofi, expired in August 2014. However, in 2016, clocking a global turnover of USD 6.05 billion, Lantus still ranked 10 in the global prescription brand league table. Six years after its patent expiry – in 2020, Lantus will continue to feature in the rank 20, as the same EvaluatePharma report estimates.

These examples give a feel that unlike small molecule blockbuster drugs, patent expiry is still not end of the road to retain this status for most large molecule biologics, across the world. In this article, I shall discuss this point taking Humira as the case study.

What about biosimilar competition?

In any way, this does not mean that related biosimilars are not getting regulatory approval in the global markets, post-patent expiry of original biologic drugs, including the United States. Nonetheless, biosimilar makers are facing new challenges in this endeavor, some of which are highly cost intensive, creating tough hurdles to make such drugs available to more patients at an affordable price, soon enough. It happened for the very first biosimilar to Humira, as well. On September 23, 2016, almost immediately after its patent expiry in 2016, the USFDA by a Press Release announced approval for the first biosimilar to Humira (adalimumab). This was Amgen’s Amjevita (adalimumab-atto), indicated for multiple inflammatory diseases.

The second biosimilar to AbbVie’s Humira – Boehringer Ingelheim’s Cyltezo (adalimumab-adbm), was also approved by the USFDA in August 2017. So far, six biosimilars have been introduced in the United states. But, none of these got approved as an ‘interchangeable’ product. Some of these, such as Cyltezo could not even be launched, as yet. I shall discuss this point later in this article. Thus, Humira is expected to retain its top global prescription brand ranking in 2020 – over 4 years after its patent expiry.

In Europe, two marketing authorizations were reportedly granted by the European Commission (EC) in March 2017 for Amgen’s biosimilars to Humira, named Amgevita (adalimumab) and Solymbic (adalimumab). Later this year, in November 2017 Boehringer Ingelheim’s – Cyltezo also received its European marketing approval.

It is worth noting that in December 2014, the Drug Controller General of India (DCGI) reportedly granted marketing approval for Zydus Cadila’s Adalimumab biosimilar (Exemptia) for treating rheumatoid arthritis and other autoimmune disorders in India. The company claims: “This novel non-infringing process for Adalimumab Biosimilar and a novel non-infringing formulation have been researched, developed and produced by scientists at the Zydus Research Centre. The biosimilar is the first to be launched by any company in the world and is a ‘fingerprint match’ with the originator in terms of safety, purity and potency of the product.”

Several important reasons indicate why a full throttle competition is lacking in the  biosimilar market early enough – immediately after patent expiry of original biologic molecules. I shall cite just a couple of these examples to illustrate the point. One is related to aggressive brand protection, creating a labyrinth of patents having different expiry dates. And the other is a regulatory barrier in the form of drug ‘interchangeability’ condition, between the original biologic and related biosimilars:

In the labyrinth of patents:

The most recent example of innovator companies fiercely protecting their original biologic from the biosimilar competition by creating a labyrinth of patents is Boehringer Ingelheim’s Cyltezo. This is biosimilar to AbbVie’s Humira, approved by the USFDA and EC in August 2017 and November 2017, respectively.

According to reports: “BI does not intend to make the drug commercially available in Europe until the respective SPC (supplementary protection certificate) for adalimumab, which extends the duration of certain rights associated with a patent, expires in October 2018. Cyltezo is also not yet available in the US despite its approval there in August, because of ongoing patent litigation with AbbVie. AbbVie reportedly holds more than 100 patents on Humira, and believes that Boehringer could infringe 74 of these with the launch of its biosimilar. Similarly, the firm has also taken Amgen to court to block the launch of its proposed Humira biosimilar.”

Another interesting example is the epoch-making breast cancer targeted therapy Trastuzumab (Herceptin of Roche/Genentech). The patent on Herceptin reportedly expired in 2014 in Europe and will expire in the United States in 2019. The brand registered a turnover of USD 2.5 billion in 2016. However, a November 21, 2017 report says that creating a series of hurdle in the way of Pfizer’s introduction to Herceptin biosimilar, Roche has sued Pfizer for infringement of 40 patents of its blockbuster breast cancer drug. Pfizer hasn’t yet won approval for its Herceptin biosimilar, though, USFDA accepted its application in August 2017 – the report highlights

‘Interchangeability’ condition for biosimilars:

In the largest global pharma market – the United States, USFDA classifies biosimilars into two very distinct categories:

  • Biosimilars that are “expected to produce the same clinical result as the reference product”
  • Biosimilars that are “interchangeable,” or able to be switched with their reference product

According to reports, experts’ argument over ‘interchangeability’ in the US range from “whether pharmacists should be allowed to switch a biologic for its biosimilar without a doctor’s notification, to whether interchangeable biosimilars might be perceived as better or safer than their non-interchangeable counterparts.” This debate has somewhat been resolved by the US Food and Drug Administration’s (FDA) issuance of draft guidance in January 2017, specifying what should be submitted to support an interchangeable application, the report says.

The article also indicates, “the draft makes clear that switching studies to help gain this designation should evaluate changes in treatment that result in two or more alternating exposures (switch intervals) to the proposed interchangeable product and to the reference product. Study design, types of data and other considerations are also included in that draft.” Nonetheless, compliance with this regulatory requirement is expected to be highly cost intensive, too.

Quoting a senior USFDA official, a report dated June 26, 2017 mentioned: “interchangeable biosimilars will come to market within the next two years, though possibly sooner. And the first interchangeable biosimilar will likely be reviewed by an FDA advisory committee of outside experts.” Still the bottom line remains no biosimilar has yet been approved by the USFDA as ‘interchangeable’. Hence, the optics related to desirable success for biosimilars continue to remain somewhat apprehensive, I reckon.

Patent related litigations on Trastuzumab (Herceptin) were filed by Roche in India, as well. However, it’s good to note that on December 01, 2017, by a Press Release, USFDA announced the approval of Mylan’s biosimilar variety of Roche’s blockbuster breast cancer drug – Herceptin. Mylan’s Ogivri was co-developed with Biocon in India to treat breast or stomach cancer, and is the first biosimilar approved in the United States for these indications. It is noteworthy that Ogivri also has not been approved as an interchangeable product.

The global and local scenario for biosimilars:

Be that as it may, the July 26, 2017 study of Netscribes – a global market intelligence and content management firm estimates that the global biosimilar market will be worth USD 36 billion by 2022. Some of the major findings of this study are as follows:

  • With a cumulative share of nearly 85%, North America, Europe, and Japan are the major contributors to global biological and biosimilar sales. Asia and Africa account for 13.2% and 1.2%, respectively.
  • Pfizer is the leading player in the biologic market, with sales of nearly USD 45.9 billion in 2016 followed by Novartis (41.6 billion) and Roche (39.6 billion).
  • Biosimilar approvals are estimated to be around of around 16 to 20 biosimilars between 2018 to 2021 in both US and EU.
  • The US is not a favorable market for biosimilars due to a number of reasons, such as poor access to biologic drugs and an unfavorable regulatory environment.
  • South Africa is one of the best-suited markets for biosimilars due to a favorable regulatory environment and prescriber acceptance.

According to the April 2017 analysis of Research And Markets, biosimilars have started winning key government tenders in countries like Mexico and Russia, and being purchased by a growing number of patients in self-pay markets such as India. The aggregate sales of ‘copy biologics’ in the six BRIC-MS (Brazil, Russia, India, China, Mexico, and South Korea) countries would now almost certainly exceed USD 1.5 billion. Yet Another estimate  expects the Indian biosimilar market to increase from USD 186 million in 2016 to USD 1.1 billion in 2020. It is up to individual experts to assess whether or not this growth trend for biosimilars is desirable to adequately benefit a large number of patients, the world over.

Conclusion:

In my view, if what usually happens to sales and profit for small molecule blockbuster drugs post patent expiry, would have happened to the large molecule biologic drugs, the market scenario for biosimilars would have been quite different. In that scenario, one would have witnessed a plethora of biosimilar competition against high priced and money churning biologics, such as Humira, being launched with a significantly lesser price than the original brand.

Prices of biosimilars would have been much lesser primarily because, the litigation cost, now built into the biosimilar prices for successfully coming out of the labyrinth of patents after the basic patent expiry, would have been minimal. Moreover, restrictions on drug ‘interchangeability’ would not have made the target market smaller, especially in the United states.

Alongside, compliance with the regulatory need to meet the ‘interchangeability’ condition in the US, would drive the product cost even higher. More so, when this specific regulatory requirement is not necessary in other developed markets, like Europe. Both these factors would adversely impact affordability and access to sophisticated biologic drugs for patients, even after the fixed period of market exclusivity.

That said, a virtually impregnable patent labyrinth mostly ensures that going off-patent isn’t end of the road for blockbuster biologic drugs to continue generating significant revenue and  profit, any longer – and it would remain so at least, in the short to medium term.

Is Criticizing Pharma Now Just A Fad?

Posted on by

Is criticizing pharma now just a fad of its stakeholders? Fathoming the right answer to this seemingly simple question may not be too easy, either, for some. The task could even be more onerous, especially when the global ‘researched based’ pharma and biotech companies, well chorused by their trade associations, are exerting serious efforts to garner the much required trust of all stakeholders on their ‘patient centric’ focus in the process of transacting business.

This often repeated pledge, as it were, on ‘patient centric’ approach is indeed praiseworthy. There’s no two opinions about it, either. The new found interest of several ‘research-based’ pharma and biologic players to develop less expensive biosimilar drugs, to possibly improve patient access to otherwise expensive biologic medicines, post patent expiry, could well be a reiteration of the same and well publicized vow, of course if not proven otherwise.

A recent example:

In the context of ‘patient-centric’ approach with biosimilar product development by the world’s largest innovative biologic drug makers, let me quote the following recent example.

On September 23, 2016, by a Press Release, the Food and Drug Administration of the United States (US-FDA) announced regulatory approval of Amjevita (adalimumab-atto) as a biosimilar to Humira (adalimumab) for multiple inflammatory diseases. This is the fourth FDA-approved biosimilar, after the new biosimilar pathway became effective in the US. Amjevita has been developed by Amgen Inc. – one of the global pioneers in the development of innovative biologic drugs.

According to US-FDA, a biosimilar is a biological product that is approved based on a showing that it is highly similar to an already-approved biological product and has no clinically meaningful differences in terms of safety, purity and potency (i.e., safety and effectiveness) from the reference product, in addition to meeting other criteria specified by law.

Although, Amjevita is biosimilar to Humira,  it has not been approved as an interchangeable product with Humira. This issue is considered as a major regulatory roadblock in the US for substitution of original biologic brands with their biosimilar equivalents, which can, therefore, be prescribed mostly to the new patients. It’s worth noting here that Humira – the blockbuster arthritis drug of AbbVie Inc. clocked a sale of US$ 14 billion in 2015, and probably will continue to do so in the foreseeable future, even long after patent expiry. I shall touch upon that point below, briefly.

It is estimated that the savings of putting just new patients on much less expensive biosimilar drugs, sans substitution of the expensive original brand, will be billions of dollars. Nonetheless, this will help reduce the cost of treatment with biologic medications, improving their access to many others.

A key barrier:

Interestingly, the barriers to following the biosimilar path are being mostly created none other than the innovative drug companies themselves, even post patent expiry, presumably to extend market exclusivity and monopoly pricing.

Arising out of one such key barrier, in the form of patent litigation, Amgen’s Amjevita, in all probability, may not be available to deserving patients for years. This could involve a protracted process of skillfully navigating through the labyrinth of legalities.

On August 05, 2016, The Wall Street Journal (WSJ) reported that AbbVie Inc. has filed a patent-infringement lawsuit against rival Amgen Inc., seeking to block sales of a lower-priced biosimilar of AbbVie’s top-selling, now generally considered as an off-patent drug – Humira.

When the narrative gets paradoxical:

While all the ‘research-based’ drug companies claim to be ‘patient-centric’ in their business approaches, be it with the development of biosimilars or in other areas, somewhere this narrative gets paradoxical.

On September 02, 2016, Reuters reported that global ‘research-based’ companies are now ‘waging courtroom patent battles against each other over biosimilars, as the line blurs between companies known for their innovative medicines, and those that produce cheaper biotech knockoffs.’

Some of the recent high-profile examples were reported as follows:

  • Sanofi sued Merck in the US federal court over its biosimilar version of Lantus insulin with around US$7 billion in annual sales.
  • Eli Lilly reached a royalties deal with Sanofi to end a similar Lantus-related lawsuit, but their pact means the biosimilar launch was likely delayed.
  • Pfizer and Korea’s Celltrion in August beat back a court challenge from Johnson & Johnson over US$10 billion autoimmune drug Remicade, though J&J’s Janssen unit promised to appeal.
  • In a closely watched case, Novartis wants the US Supreme Court to dump a six-month marketing delay for biosimilars, in what would be the first time the high court took up a biosimilar case.
  • Samsung Bioepis, along with partner and minority shareholder Biogen Inc, filed a lawsuit against AbbVie in Britain in March to stop the US company from blocking the launch of yet another Humira biosimilar.

It is equally noteworthy, while Amgen is keen to launch its own biosimilars, the company’s aggressive legal strategy delayed Novartis’s efforts to introduce the first US biosimilar, Zarxio, before the copy of Amgen’s US $1 billion drug Neupogen finally went on sale last year.

Further, Amgen has also filed a legal suit against a biosimilar version of its Enbrel (etanercept) developed by Novartis (Sandoz), which has already received regulatory approval from the US-FDA on August 30, 2016 for multiple inflammatory diseases.

Taking these into consideration, isn’t, therefore, about time to ponder afresh, whether the innovative drug makers’ general mindset of maintaining drug exclusivity with a very high price, on techno-legal grounds, even after enjoying price monopoly over a long period of the specified time, be termed as ‘patient-centric’?

Indian scenario:

Indian players have already started developing biosimilar drugs in the country. This market offers a lucrative future opportunity considering that original biologic brands with a global turnover of around US$ 70 billion will expire by 2020.

The first biosimilar was approved and marketed in India for a hepatitis B vaccine in 2000 (GaBI Online). By now, around 30 such products have reportedly received the Drug Controller General of India (DCGI)’s approval for marketing in India. Even after the new biosimilar guidelines were framed and implemented locally, since 2012, there has not been any worthwhile legal suits filed by the global innovative biologic manufacturers, against the Indian companies or such products developed and approved in India, till 2014.

Since then, this scenario has changed with Roche suing Biocon and its partner Mylan on their biosimilar versions of Roche’s Herceptin (Trastuzumab) for breast cancer, and also making the DCGI a party to this suit. This litigation is broadly on the following grounds:

  • Non-adherence to the Indian biosimilar guidelines
  • Misrepresentation of drugs as biosimilar and passing off 

Be that as it may, its key impact is on affordable biosimilar drugs that can save more lives of breast cancer patients in India. If it is so, do such litigations demonstrate a patient-centric perspective for so important a drug, which is not even protected by a product patent in India, any longer?

Are biosimilars the only examples?

Lest I am not seen as highlighting only the instances of blocking market entry of biosimilar drugs, as sole examples of ‘patient-centric focus’, or lack of it, of many global innovative drug manufacturers, I would now expand it, just a bit. This is only to fathom the bottom-line – whether it is a ‘patients-centric’ focus, or solely a ‘profit-centric’ outlook.

‘Patients-centric’ or ‘Profit-centric’?

To get a sense on this vexing issue, it would be worthwhile for us to find out by ourselves the most appropriate reason behind each of the following. Of course it’s just an illustration. This reason could be either a ‘patient centric’ focus, or simply a ‘profit centric’ outlook. …And then let’s try to make out which way the overall balance tilts, on the ground:

  • Discovering new drugs, delivery systems, and finding new indications
  • Lack of transparency and widely reported bias towards mainly positive results in clinical trial data, both for publication and regulatory approval of various new drugs, and associated global furor.
  • Exorbitant high prices of many new patented medicines and some generic drugs too
  • Widely reported marketing/other malpractices, and associated fines paid by the respective players
  • Causing entry delay for cheaper small molecule generics and large molecule biosimilar drugs post patent expiry restricting gtreaterr patient access

What’s your relative score now?

Conclusion:

Let me sign off here by raising the following relevant questions in this area, for all of us to think and address, as we deem appropriate:

Is the narrative of ‘patient centric’ approach of the ‘research-based’ global drug companies’ now getting clearer with the widely reported credible examples, as above?

Is there still a paradox between their two different strategic business approaches – one entry into off-patent drug development, such as biosimilars, and the other in blocking or delaying entry of such drugs, whenever possible, even after enjoying a specified period of product pricing monopoly?

Does it then mean, what a large section of pharma industry constituents is now publicly demonstrating, at least in the above areas, more than negates their protracted sound bites on ‘patient centric’ focus?

Despite these facts, would pharma related criticism in this space be termed as just a fad of the stakeholders?

If not, what should be the way forward from here to ensure that remedial measures are taken in so important an area of ‘patient-centric’ outlook, soon enough?

An Emerging Yo-Yo Syndrome With Biosimilar Drugs

Posted on by

Competition from Biosimilar drugs poses a threat of a combined revenue loss of estimated US$ 110 billion of those pharma players who are still enjoying market monopoly with patented biologic brands. This is expected to surely happen, in the long run, if the signals picked up from the evolving scenario continue to stay on course.

Simply speaking, generic versions of original biologic drugs are termed as Biosimilars. These are large protein molecules, created from living organisms following complex processes. Thus, it is significantly more expensive to develop and market biosimilar drugs, as compared to any small molecule generic chemical ones. 

Hurdle creation and the core intent: 

Despite these complexities, for quite some time, global original biologic drug players had initiated intense campaign to create tough hurdles in the process of regulatory and marketing approval for biosimilar drugs, predominantly raising safety concerns. A simultaneous campaign was also launched among doctors and the payers in the developed countries, stoking the same fear, to forestall the overall acceptance of biosimilar drugs.

When drug regulators of different countries are solely responsible to ensure patient safety of any drug, why are the global pharma companies, and their trade associations are continually shouting from the roof top expressing concerns in this regards? It is often seen that such campaigns become more intense, when it comes primarily to block or delay the entry of biosimilar, many generic drugs and some IP related issues in a country. Umpteen number of such examples are available from India, Europe, United States and many other countries. Many would agree that in such cases, the core intent is as important as the issue.

I discussed on those hurdle creating campaigns in my article in this Blog, on August 25, 2014, titled, “Scandalizing Biosimilar Drugs With Safety Concerns”. Hence won’t dwell on that again here.

The campaign yielded results:

This campaign of global bio-pharma majors to restrict the entry of lower priced biosimilar drugs into the market, immediately after patent expiry, has been successful to a great extent, so far. Let me now give below a recent example, from credible sources, to vindicate this point.

Although, the world’s number 1 drug in sales – Humira (Adalimumab), with a turnover of US$ 15 Billion in 2015 (IMS Health), is going off patent in December 2016, no biosimilar version of Adalimumab is ready, just yet, to compete with this profit churning blockbuster biologic brand, in the United States. More interestingly, according to another report dated July 14, 2016 of the Wall Street Journal (WSJ), even on the verge of its product patent expiration this year, U.S. sales of Humira rose 32 percent to US$ 2.2 billion in the first quarter this year, with over 16 percent jump in its prescription volume.

It is worth noting, Humira was first approved in 2002, and has long been one of the most profitable drugs, globally, contributing around 60 percent of Abbvie’s total revenue even in the last year.

The industry may well argue, in a situation like this, how can a pharma company possibly decide to remain within the ambit of just patent protection, even if it leads to sacrificing other stakeholders’ interest? That’s a ‘business ethics’ issue, and is beyond the scope of this article.

The beginning of a yo-yo syndrome:

At the very outset, let me mention that the term ‘yo-yo syndrome’ has been coined to refer to something that moves up and down quickly, or something that changes repeatedly between one level and another.

Keeping this into perspective, some of the big bio-pharma companies, such as, Amgen, which have been, reportedly, trying hard to block the on-time entry of biosimilar drugs, through litigations and lobbying, could stand as good examples in this area.

For instance, Amgen, on the one hand, seem to be vigorously shielding its over US$10 billion of annual biologic sales from the biosimilar competition through powerful lobbying. Whereas, on the other, it commenced developing its own biosimilar drugs, to reap a rich harvest from the available opportunities.

According to an Associated Press report on July 12, 2016, a panel of Food and Drug Administration advisers of the United States has voted unanimously in favor of Amgen’s version of AbbVie’s Humira. While not binding, the recommendation could help the USFDA approval of the knockoff drug.

According to reports, the companies now working on Humira biosimilars, include Novartis, Mylan and Baxter.

India did it, but a tough road ahead:

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.” That said, let me hasten to add that Humira does not have a valid product patent protection in India.

Yet another good news is, according to a Press Release of Biocon dated July 15, 2016, its India made Insulin – Glargine was launched in Japan on the same day by its partner FUJIFILM Pharma Co., Ltd. (FFP).

These are excellent developments, and music to many ears. However, on the flip side, intense legal battle on various regulatory grounds against the Indian biosimilar drug players, by the makers of original biologic to protect their own turf of market monopoly, has also commenced with associated acrimony.

Earlier, the Swiss drug major – Roche had objected to Biocon’s referring to Herceptin at an international scientific conference, related to clinical trial results of its own ‘biosimilar’ version Herclon (trastuzumab).

On April 2016, responding to Roche’s complaint, the Delhi High Court ordered changes to the packaging labels of the brands sold by Biocon, and other bio-pharma companies in India, such as, Reliance Life Sciences and Mylan. The court also raised questions about the DCGI’s approval processes for biosimilars, and restrained the companies from using Roche’s data related to the manufacturing process, safety, efficacy and tests.  

More recently, this issue between Roche and Biocon, over breast cancer drug trastuzumab has reportedly taken another acrimonious turn with both the companies approaching the Delhi High Court on charges of contempt of court.

Roche reportedly also alleged contempt over Biocon using the name ‘Herceptin’ in the approval process of its trastuzumab drug in the United States. According to reports, Biocon is currently conducting Phase III clinical trials for marketing approval of its trastuzumab in the U.S.

Thus, to carve out a niche in the biosimilar space of the world, Indian pharma has made some good progress. Alongside, taking note of many contemporary factors and development in this area, a lurking apprehension too did creep in. It raises an awkward and uncomfortable question – do the Indian companies have pockets deep enough to overcome the expensive legal and regulatory challenges thrown by the global biologic drug makers to protect their market monopoly status for expensive drugs, much longer than what they deserve?

Let me keep my fingers crossed.

Critical global speed-bumps for biosimilar entry:

Besides, many other hurdles, as I highlighted in my article of August 25, 2014, the intricate patent shield beyond original patent expiry, is a major speed bump for biosimilar drugs’ smooth global market entry. 

Maintaining the same example of Humira, a well crafted patent-shield strategy was implemented to extend market monopoly of this brand, at least for another decade. Although, the main patent of Humira expires in December 2016, it is reportedly well shielded, at least, with 70 other patents till 2027, as many reports indicate.

This is possible because, according to a January 19 2016 report by Bloomberg, the U.S. patent office in the same month rejected Amgen’s effort to knock out two patents on AbbVie’s anti-inflammatory bestseller Humira. Amgen hoped to get its Humira competitor to market by 2017. This is a bad news for other biosimilar drug makers too.

Nevertheless, the good news is, in May 2016, the Patent Trial And Appeal Board (PTAB) announced that it would embark on a review of Coherus’ challenge of Humira’s ’135 methods patent. Experts believe, even if it the PTAB upturns Humira’s IP shield, AbbVie could appeal, which could take another year or so.

Recent status:

So far, after the biosimilar guidelines were put in place for the first time in the United States, a Novartis version of Amgen’s Neupogen, got USFDA approval in March 2015, only after so many delays and protracted litigations. Novartis is also trying to to do the same for Amgen’s Enbrel. Pfizer too won the U.S drug regulator’s approval in April 2016 for a version of Johnson & Johnson’s Remicade, but the product is still not available for sale.

Currently, some constituents of Big Pharma, such as, Amgen, Novartis and Pfizer have started warming up for manufacturing copycat versions of blockbuster original biologic drugs of other companies.

High quality biosimilars:

These new biosimilars are of top quality. Even USFDA could not find any meaningful differences in the key parameters, such as, efficacy, safety, potency and purity, between the original biologic drugs and their biosimilar versions.

According to a July 12, 2016 Bloomberg report, in several cases USFDA finds the clinical results of biosimilar drugs are robust enough to support ‘extrapolation’. This could support approval of these biosimilar drugs for all indications that the original biologic brands treat, without requirement of separate clinical trials for each, facilitating the approval process and accelerating their market entry.

With these developments, the high voltage lobbying campaigns of the original biologic makers, and their trade associations, both to the drug regulators and doctors, are expected to lose steam, if not ultimately die down altogether. 

However, the protracted and fierce legal battles of the originators, creating various intricate patent shields, to enjoy a brand monopoly for a much longer period, are expected to continue, if not turn fiercer.

The question of price advantage with biosimilars:

Currently the cost advantage provided by the biosimilar drugs over the original biologics, does not come anywhere near to what we see for small molecule generic drugs, post patent expiry. 

For example, Zarexio of Novartis has been priced 15 percent less than the original Neupogen of Amgen. It is generally believed that in the united states this difference would continue to be around 15 to 30 percent, in the near future. Whereas in Europe, the difference is higher, as the governments regulate their prices.

In India too, the difference in the pricing trend is currently, more or less, similar. 

Nonetheless, the above report of Bloomberg had quoted the global CEO of Novartis Joe Jimenez saying that biosimilar drugs would eventually cost 75 percent less than the original biologics. 

Let’s hope so.

Conclusion:

The powerful constituents of Big Pharma who decided to delay, if not stall the entry of biosimilar drugs for vested interest, have now started adopting a dual strategy. They did not have any other choice either, after President Obama’s fulfillment of his election promise with the ‘Affordable Care Act’, which, among others, facilitated charting the regulatory pathway for entry of biosimilar drugs in the United States, for the first time ever. 

Thus, on the one the one hand, these companies continued crafting robust patent-shields to extend market monopolies, even beyond the original patent expiries, through protracted and complicated litigations. While, on the other, started moving with great speed to develop biosimilar versions of the original blockbuster biologic drugs of other players, as they go off patent. This is mainly to cash-in the golden opportunities, which otherwise would go to different players.

India has made an entry into this space, but would still require a lot to do, including winning the expensive legal battles, in order to be recognized as a global force to reckon with, in the biosimilar segment.

To facilitate rapid growth, and universal acceptance of biosimilar drugs, for patients’ interest across the world, it will be interesting to follow the spread of the ‘yo-yo syndrome’ of the original biologic drug makers, as we move on.

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

Posted on by

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?

More Glivec Like Deals in China and Mounting Global Challenges: Innovators poised Joining Biosimilar Bandwagon

Posted on by
Reply

Pressure from the emerging markets on pricing of patented products is mounting fast. This time the country involved is China.

Recently, the Health Minister of China who stepped down last month after a seven-year stint in the top health job reportedly commented that western drugmakers will require to give hefty subsidies and forgo significant amount of profit on expensive cancer drugs, if they want access to huge market of China. He further voiced as follows:

“If the cost (of patented drugs) is too high, maybe only a few percent of patients can benefit. If we can arrange an appropriate, acceptable, affordable price, then you can have a huge market.”

‘Glivec deal’ in China: 

In the same report, it was indicated that in China Novartis ultimately agreed to donate three doses of its leukemia drug Glivec for every one sold to the government.

It is expected that many more such deals will take place in China.

The situation to get more challenging in the emerging markets: 

Many experts believe that due to high cost of patented drugs, especially biologics, negotiating hefty discounts with the Governments may be the best alternative for the innovator companies to avoid any possibilities of Compulsory Licensing (CL), like what happened to Bayer’s cancer drug Nexavar in India.

An opportunity in biosimilar drugs: 

Biologic drugs came to the international market slightly more than three decades ago, in 1980s. Growing at a scorching pace, the value turnover of these products exceeded US$ 138 billion in 2010 (IMS Health).

Launch of biologics like, Recombinant Insulin, Human Growth Hormone (HGH), Alteplase, Erythropoietin (EPOs), Granulocyte Colony Stimulating Factors (G-CSFs) and Monoclonal Antibodies (MAbs) kept fueling the market growth further.

Patent expiry of a number of biologic drugs over a period of next five years, especially in areas like, various types of cancer, diabetes and rheumatoid arthritis, besides many others, will help opening a huge window of opportunity for the global biosimilar players, including from India, to reap a rich harvest.

Global innovators joining the bandwagon: 

After a dream-run with high priced patented drugs for a reasonably long time, now stung by the current reality in various developed and emerging markets and factoring-in the width/depth/robustness of their own research pipeline, many global players have started taking a hard look at the emerging opportunities offered by biosimilar drugs.

Moreover, high price of original biologic drugs, cost containment pressure by various Governments, encouragement of generic prescriptions, large number of such drugs going off patent and growing demand of their low cost alternatives across the world, are making biosimilar market more and more lucrative from the global business perspective to all interested players, including from India.

According to Bloomberg Industries (2013), during the next six years biologic drugs with a total annual sales turnover of US$ 47 billion in 2012, will go off patent.

Sniffing opportunities for business growth, as stated above, many hard-nosed large research-based global pharmaceutical companies, currently fighting a challenging battle also in the ground of a tougher ‘patent cliff’, have started venturing into the biosimilar market, that too in a mega scale.

Some of them have already initiated developing biosimilar versions of blockbuster biologics, as reported below:

Originator Product Indication Biosimilar development by:
Roche/Genentech Rituxan Rheumatoid arthritis Boehringer Ingelheim
Roche/Genentech Herceptin, Rituxan Breast Cancer, Rheumatoid arthritis Pfizer
Roche/Genentech Rituxan Non-Hodgkin’s lymphoma Novartis
Johnson & Johnson Remicade Rheumatoid arthritis Hospira

Source: Bloomberg BusinessWeek

Thus, I reckon, continuous quest for development of cost-effective alternatives to high-priced biologic medicines would keep on propelling the growth of biosimilar drugs, across the world.

Glivec maker Novartis fought a court battle to launch the first ‘Biosimilar drug’ in America: 

In mid-2006, US FDA approved its first ‘biosimilar drug’-Omnitrope of Sandoz, the generic arm of the Glivec maker Novartis, following a Court directive. Omnitrope is a copycat version of Pfizer’s human growth hormone Genotropin. Interestingly, Novartis had also taken the US FDA to court for keeping its regulatory approval pending for a while in the absence of a well-defined regulatory pathway for ‘biosimilar drugs’ in the USA at that time.

More interestingly, having received the US-FDA approval, the CEO of Sandoz (Novartis) had then commented as follows:

“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”.

Biosimilar market started shaping-up:

Internationally most known companies in the biosimilar drugs space are Teva, Stada, Hospira and Sandoz. Other large research based global innovator pharmaceutical companies, which so far have expressed interest in the field of biosimilar drugs, are Pfizer, Astra Zeneca, Merck and Eli Lilly.

Following are examples of some biosimilar drug related initiatives of the global players as the market started developing:

  • Merck announced its entry into the biosimilar drugs business on February 12, 2009 with its acquisition of Insmed’s portfolio for US$ 130 million. The company also paid US$ 720 million to Hanwha for rights to its copy of Enbrel of Amgen.
  • Samsung of South Korea has set up a biosimilars joint venture with Quintiles to create a contract manufacturer for biotech drugs.
  • Celltrion and LG Life Sciences have expressed global ambitions in biosimilar drugs.
  • Some leading global innovator biotech companies also like, Biogen Idec and Amgen have reportedly been mulling entry into biosimilar market.

According to Reuter (June 22, 2011), Merck, Sandoz, Teva and Pfizer are expected to emerge stronger in the global biosimilar market, in the years ahead. 

Why is still so low penetration of lower cost biosimilar drugs?

Although at present over 150 different biologic medicines are available globally, just around 11 countries have access to low cost biosimilar drugs, India being one of them. Supporters of biosimilar medicines are indeed swelling as time passes by.

It has been widely reported that the cost of treatment with patented biologic drugs can vary from US$ 100,000 to US$ 300,000 a year. A 2010 review on biosimilar drugs published by the Duke University highlights that biosimilar equivalent of the respective biologics would not only reduce the cost of treatment, but would also improve access to such drugs significantly for the patients across the globe. (Source: Chow, S. and Liu, J. 2010, Statistical assessment of biosimilar products, Journal of Biopharmaceutical Statistics 20.1:10-30)

Now with the entry of global pharma majors, the biosimilar market is expected to get further heated up and develop at a much faster pace with artificial barriers created by vested interests, if any, being removed.

Recent removal of regulatory hurdles for the marketing approval of such drugs in the US  will indeed be the key growth driver.

Other growth drivers:

According to a study (2011) conducted by Global Industry Analysts Inc., besides recent establishment of the above regulatory guidelines for biosimilars in the US, the key growth drivers for global biosimilar market, will be as follows:

▪   Patent expiries of blockbuster biologic drugs

▪   Cost containment measures of various governments

▪   Aging population

▪   Supporting legislation in increasing number of countries

The business potential in India:

The size of biotech industry in India is estimated to be around US$ 4 billion by 2015 with a scorching pace of growth driven by both local and global demands (E&Y Report 2011).

The biosimilar drugs market in India is expected to reach US$ 2 billion in 2014 (source: Evalueserve, April 2010).

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 like, Biocon, Panacea Biotech, Wockhardt, Emcure, Bharat Biotech, Serum Institute of India and Dr. Reddy’s Laboratories (DRL), besides others.

DRL is the largest biosimilar player in India with an impressive product portfolio. Reditux of DRL is the world’s first Biosimilar monoclonal antibody, which is a copy version of Mabthera/ Rituxan of Roche and costs almost 50 percent less than the original brands.

Some of the Biosimilar products of the Indian Companies are as follows:

Indian Company

Biosimilar Product
Dr Reddy’s Lab Grafeel, Reditux, Cresp
Intas Neukine, Neupeg, Intalfa, Epofit
Shantha Biotech/Merieux Alliance Shanferon,Shankinase,Shanpoietin
Reliance Life Sciences ReliPoietin, ReliGrast, ReliFeron, MIRel
Wockhardt Wepox, Wosulin
Biocon Eripro, Biomab, Nufil, Myokinase, Insugen

The cost of development of Biosimilars in India is around US$ 10-20 million, which is expected to go up, as “Biosimilar Guidelines” are now in place for marketing approval of such products in India.

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

Indian players making rapid strides:

As stated above, biosimilar version of Rituxan (Rituximab) of Roche used in the treatment of Non-Hodgkin’s lymphoma has already been developed by DRL in India. It also has developed Filgastrim of Amgen, which enhances production of white blood cell by the body and markets the product as Grafeel in India.

Similarly Ranbaxy has collaborated with Zenotech Laboratories to manufacture G-CSF.

On the other hand Glenmark reportedly is planning to come out with its first biotech product soon from its biological research establishment located in Switzerland.

Indian pharmaceutical major Cipla reportedly has invested around US$ 60 million in 2010 to acquire stakes of MabPharm in India and BioMab in China and is planning to launch a biosimilar drug in the field of oncology by 2013.

Another large pharmaceutical company of India, Lupin signed a deal with a private specialty life science company NeuClone Pty Ltd of Sydney, Australia for their cell-line technology. Lupin reportedly will use this technology for developing biosimilar drugs in the field of oncology, the first one of which, will reportedly be launched in India by 2013.

The global Market:

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

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

According to IMS Health report, by 2015, sales of biosimilars are expected to reach between US$ 1.9 – 2.6 billion. The report also states that this market has the potential to be the single fastest-growing biologics sector in the next five years.

Cost of biosimilar development in the developed markets:

The process of developing a biosimilar drug is complex and requires significantly more investment, technical capabilities and clinical trial expertise than any small molecule generic drug. As per industry sources, average product developmental cost ranges between US$ 100 and 250 million in the developed markets, which is several times higher than the same associated with development of small molecule generics, ranging around US$ 1to 4 million.

All these factors create a significant market entry barrier for many smaller players with similar intent but less than adequate wherewithal.

Even higher market entry barrier with ‘second generation’ biosimilar drugs:

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

Negotiating the entry barriers:

As stated above, the barriers to market entry for biosimilar drugs are, in general, are much higher than any small molecule generic drugs. In various markets within EU, many companies face the challenge of higher development costs for biosimilar drugs due to stringent regulatory requirements and greater lead-time for product development.

Navigating through such tough regulatory environment will demand different type of skill sets, especially for the generic companies not only in areas of clinical trials and pharmacovigilance, but also in 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.

The future potential:

According to an IMS Health study, the emerging markets will drive biosimilar market growth with significantly more number of patients. The report estimates that over a period of time US will emerge as the number one global biosimilars market.

By 2020, emerging markets and the US are expected to register a turnover of US$11 billion and US$ 25 billion representing a share of 4 percent to 10 percent of the total global biologics market, respectively.

The report estimates that overall penetration of biosimilars within the off-patent biological market will reach up to 50 percent by 2020, assuming a price discount in the range of 20 to 30 percent.

Is 12 years exclusivity in the US a significant entry barrier?

In the US, the innovator companies get 12 years exclusivity for their original biologic drugs from the date of respective marketing approvals by the USFDA.

The BPCI Act clearly specifies that applications for ‘biosimilar drugs’ to the USFDA will not be made effective by the regulator before 12 years from the date of approval of the innovators’ products. In addition, if the original product is for pediatric indications, the 12-years exclusivity may get an extension for another six months.

The key point to note here is, if the USFDA starts its review process for the ‘biosimilar drugs’ only after the ’12 year period’, the innovator companies will effectively get, at least, one additional year of exclusivity over and above the ’12 year period’, keeping applicants for ‘biosimilar drugs’ waiting for that longer.

Conclusion:

As stated above, with around 40 percent cost arbitrage and without compromising on the required stringent international regulatory standards, the domestic ‘biosimilar’ players should be able to establish India as one of the most preferred manufacturing destinations to meet the global requirements for such drugs, just as small molecule generic medicines.

With experience in conforming to stringent US FDA manufacturing standards, having largest number of US FDA approved plants outside USA, India has already acquired a clear advantage in manufacturing high technology chemical based pharmaceutical products in the country. Now with significant improvement in conformance to Good Clinical Practices (GCP) and honed skill sets in the field of biologics, Indian biosimilar players are clearly poised to catapult themselves to even a higher growth trajectory, either on their own or with appropriate collaborative arrangements with the international partners.

Thus, the initiatives of joining the biosimilar bandwagon by the hard-nosed research based global players, I reckon, will ultimately get translated into a win-win advantage for India in the rapidly evolving pharmaceutical space of the world.

Besides, like what they had to do in China, working with the Government to put in place a robust and win-win mechanism of ‘Price Negotiation for Patented Drugs’ in India could augur well for the global players of pharmaceutical and biologic drugs. This mechanism may also help putting forth even a stronger argument against any Government initiative to grant CL on the pricing ground for expensive patented drugs in India.

With all these developments, patients will be the ultimate winners having much greater access to both innovative medicines and biosimilar drugs than what they have today, fetching a huge relief to all right thinking population in the country.
