A Game-Changing Non-Covid Drug Approval In the Pandemic Milieu

Amid high decibel deliberations on Covid-19 pandemic, something similar to groundbreaking happened – involving Biosimilar drugs, in just a couple of months ago. On July 28, 2021, in the Eldorado of the pharma industry, the US-FDA approved  the first ‘interchangeable’ biosimilar drug, for wider access to modern and much affordable treatment of diabetes. This is expected to open new vistas of opportunity for biosimilar drugs, in general, across the world.

The development is even more interesting, as the product named Semglee belongs to India’s largest biopharmaceutical company - Biocon Biologic. It’s an ‘interchangeable’ biosimilar insulin glargine, referencing Sanofi’s, reportedly  the second best-selling product in 2020 - Lantus. Notably, the Biocon product was launched in 2020 without the ‘interchangeability’ designation.

Although, the patent of this long-acting insulin (glargine) – used to treat diabetes type I and II, expired during 2015, in 2020 also Lantus generated some 2.7 billion U.S. dollars worldwide. Many envisage, the approval of this first ‘interchangeable’ biosimilar insulin glargine will foster stronger competition in the insulin market, which is currently dominated by a handful of brands, like Lantus – and characterized by their stubbornly high prices.

In today’s article, I shall focus on what it means to pharma marketers for greater market access to ‘interchangeable’ biosimilar drugs.

What ‘interchangeability’ really means:

As I wrote in my article on July 31,2017, there are two key barriers to improving patient access to biosimilar drugs, and one of which is the issue of their ‘interchangeability’ with original biologic drugs. It means, besides being highly similar, a biosimilar drug would require indisputable clinical evidence – that it gives the same result to patients, just as the original biologic medicine.

Thus, lack of the ‘interchangeability’ designation makes many physicians hesitant to switch, for all those existing patients who are on expensive original biologic drugs, to less expensive available biosimilar alternatives. Only new patients in that case, are prescribed biosimilar drugs, sans ‘interchangeability’ label from the drug regulator, especially in the US.

Overcoming a tough barrier to biosimilar market growth:

This was echoed by another article on ‘Interchangeability’ of biosimilars, published in the Pharmaceutical Journal on July 22, 2020. It wrote, ‘One of the hurdles in the adoption of biosimilars is the lack of interchangeability with reference biologics.’ While interchangeability is an important issue for doctors, ‘different definitions and regulatory frameworks that exist in the United States, Europe and other jurisdictions add to the complexity.’

What the ‘interchangeable’ designation of Semglee will really mean, in terms of affordability to patients, was lucidly explained in an article, published in the AJMC – the center for Biosimilars – on July 29, 2021. It underscored: ‘An interchangeable designation means that Semglee can be substituted for Lantus automatically by pharmacists without physicians’ permission.’ As reported, Semglee will cost nearly 3 times less than the list price of Sanofi’s Lantus, which in 2019 clocked in at $283.56 for a single vial and $425.31 for a box of five pens, in the US.

Are interchangeable biosimilars superior to other biosimilars?

The ‘interchangeable’ designation is not meant to suggest that such biosimilars are superior to ones without this label. However, to obtain the ‘interchangeable’ designation, biosimilar manufacturers are required to perform ‘switching studies.’ These provide evidence that patients who are using originator’s biologic drug, when switch to a comparable biosimilar, do not experience higher rates of adverse events or decreased efficacy. The same has also been clearly explained in the AJMC article of July 29, 2021, as mentioned above.

But, if marketed well, ‘interchangeable’ biosimilars can provide a cutting edge to encourage consumers to switch to the less-expensive ‘interchangeable’ versions of the original higher priced biologic drugs. Consequently, more economical ‘interchangeable’ biosimilars would carve out a larger market share, creating a win-win situation. For patients, it will expand affordable access to biologic drugs- and for the company increased revenue from the expanding biosimilar market, as several studies point out.

Expanding biosimilar market:

According to the IQVIA report of March 04, 2021, the global biosimilars market currently shows double-digit growth and is expected to maintain a similar level of uptake in the coming years. This will be driven by the rising incidence of chronic diseases and the cost-effectiveness of biosimilars, especially as more stringent cost-containment measures are likely – post COVID-19 pandemic.

The paper concluded, biosimilars will continue to register impressive growth in their market share, aided by patent expiries and regulatory improvements which will permit easier and more rapid market access. Many pharmaceutical companies – having witnessed this trend, are now preparing to leverage the biosimilar opportunity. However, marketing large molecule biosimilar drugs will not be quite the same as marketing small molecule generics. 

Estimated savings to patients with biosimilars – in Covid-19 context:

As the IQVIA Institute estimates, over the next five years biosimilars could globally contribute a cumulative $285 billions of savings to patients and payers. To put this in context, it says, over the same period, around $150 billion will be spent on COVID-19 vaccines. According to a senior IQVIA official, as quoted by Reuters Events of July 2, 2021: “The five-year savings from biosimilars could almost double the amount of incremental spending that will be going out to get everybody vaccinated around the world.”

Going by the IQVIA data, biosimilars are between 20% and 50% more affordable. And this is especially at a time when affordability drives a lot of healthcare - sustainability that has emerged as a major issue during the pandemic.

Conclusion:

Currently, in many countries of the world, alongside Covid vaccination drive in top gear, creation of a disruptive pandemic-specific – a robust health infrastructure for the future, is yet to be in place. More importantly, public health facilities, especially in India, are still struggling hard to meet affordable health care needs of patients – sans restrictions or apprehensions of getting infected by Covid-19.

Against this backdrop, the very first approval of an ‘interchangeable’ biosimilar drug, in the Eldorado of pharma business – the US, brings a new hope to many patients, in 2021. An expectation of reducing their healthcare burden, significantly. This will happen, as the prescribers muster enough confidence to advise patients switching from highly expensive original biologic to more affordable ‘interchangeable’ biosimilar drugs, as and when these are launched.

In tandem, with this growing new confidence, others – even ‘non-interchangeable’ biosimilar drugs, will be able to deliver more value being, besides greater affordability – wider access to sustainable-treatments for patients.

This comes, possibly with a caveat. Biosimilar drug marketers will need to chart a new marketing frontier, without holding on to their pre-covid strategies – especially for large molecule biosimilar drugs.

From this perspective, the US-FDA’s regulatory approval of the first ‘interchangeable’ biosimilar insulin to Sanofi’s high-priced Lantus, carries a game-changing potential in the biosimilar drug market, for astute pharma marketers to leverage.

Improving Patient Access To Biosimilar Drugs: Two Key Barriers

Posted on by
Reply

Novel biologic medicines have unlocked a new frontier offering more effective treatment for a host of chronic and life-threatening diseases, such as varieties of cancer, rheumatoid arthritis and diabetes, to name just a few. However, these drugs being hugely expensive, many patients do not have any access, or adequate access, to them. According to the Biosimilar Council of GPhA, only 50 percent of severe Rheumatoid Arthritis patients receive biologic medicines, even in the United States, Europe and Japan, leave aside India.

Realizing the gravity of this situation, a need to develop high quality, reasonably affordable and similar to original biologic brands, was felt about ten years ago. These were intended to be launched immediately after patent expiry of the original biologic. Such medicines are termed as biosimilar drugs. It is worth noting, even biosimilar drug development involves complex manufacturing processes and handling, while dealing with derivatives of highly sensitive living organisms.

The regulatory approval process of these drugs is also very stringent, which demands robust clinical data, demonstrating high similarity, both in effectiveness and safety profile, to original biologic brands, known as the reference product. The clinical data requirements for all new biosimilars include data on patients switching from the originator’s brand, and also between other biosimilars. Clinical evidences such as these, are expected to provide enough confidence to physicians for use of these products.

An article published in the PharmaTimes magazine in January 2016, reiterated that over the last couple of years, a wealth of supporting data has been published in medical journals and presented at global congresses, including real-world data of patients who have been switched to the new drug from the originator. This has led to a positive change in physician and patient attitudes towards biosimilars.

The good news is, besides many other regulated markets, as of May 2017, five biosimilar drugs have been approved even by the US-FDA, and several others are in the pipeline of its approval process.

That said, in this article I shall mainly focus on the two key barriers for improving patient access to biosimilar drugs, as I see it.

Two major barriers and their impact:

As I see it, there appear to be the following two key barriers for more affordable biosimilar drugs coming into the market, improving patients’ access to these important biologic medicines:

  • The first barrier involves fierce legal resistance from the original biologic manufacturers of the world, on various grounds, resisting entry of biosimilar varieties of their respective brands. This compels the biosimilar drug manufacturers incurring heavy expenditure on litigation, adding avoidable cost. A glimpse of this saga, we are ‘privy’ to witness even in India, while following Roche versus Biocon and Mylan case related to ‘Trastuzumab’. This barrier is one of the most basic types, that delays biosimilar drug entry depriving many new patients to have access to lower priced effective biologic for the treatment of serious diseases.
  • The other major barrier that exists today, involves ‘interchangeability’ of original biologic with biosimilar drugs. It simple means that in addition to being highly similar, a biosimilar drug manufacturer would require producing indisputable clinical evidence that it gives the same result for any given patient just as the original biologic. We shall discuss the reason behind this regulatory requirement later in this article. However, this is an expensive process, and the absence of it creates a barrier, making the physicians hesitant to switch all those existing patients who are on expensive original biologic drugs with less expensive available biosimilar alternatives.

The first or the initial barrier:

The first or the initial barrier predominantly involves patent related legal disputes, that can only be settled in a court of law and after incurring heavy expenditure towards litigation. Provided, of course, the dispute is not mutually resolved, or the law makers do not amend the law.

An interesting case in India:

Interestingly, in India, a similar dispute has knocked the doors of both the high court and the Competition Commission of India (CCI). From a common man’s perspective, it appears to me that the laws under which these two institutions will approach this specific issue are seemingly conflicting in nature. This is because, while the patent law encourages no market competition or a monopoly situation for a patented product, competition law encourages more market competition among all related products. Nonetheless, in this specific case CCI is reportedly investigating on the alleged ‘abuse of the regulatory process’, as it has opined ‘abuse of regulatory process can constitute an abuse of dominance under the (CCI) Act.’                                                                                            

The second barrier:

I am not going to discuss in this article the relevance of this barrier, in detail. Nevertheless, this one is also apparently equally tough to comply with. The very fact that none out of five biosimilar drugs approved in the United States, so far, has been considered ‘interchangeable’ by the US-FDA, vindicates the point.

That this specific regulatory demand is tough to comply with, is quite understandable from the requirements of the US-FDA in this regard, which goes as follows:

“To support a demonstration of interchangeability, the data and information submitted to FDA must show that a proposed interchangeable product is biosimilar to the reference product and that it can be expected to produce the same clinical results as the reference product in any given patient. Also, for products that will be administered more than once, the data and information must show that switching a patient back and forth between the reference product and the proposed interchangeable product presents no greater risk to the patient in terms of safety or diminished efficacy when compared to treating them with the reference product continuously.”

The reasoning of innovative biologic drug makers:

On this subject, the stand taken by different innovative drug makers is the same. To illustrate the point, let me quote just one of them. It basically sates, while biosimilar drugs are highly similar to the original medicine, the patient’s immune system may react differently due to slight differences between the two medicines when they are alternated or switched multiple times. This phenomenon, known as immunogenicity, is not a common occurrence, though. But there have been rare instances when very small differences between biologic medicines have caused immune system reactions that changed the way a medicine was metabolized, or reduced its effectiveness.

It further reiterates, the US-FDA requirements to establish ‘interchangeability’ between a biosimilar drug and the original one, or between biosimilars may seem like nuances, but are important because ‘interchangeability’ allows pharmacists to substitute biosimilars without consulting the doctor or patient first.

It may, therefore, indicate to many that innovative biologic drug manufacturers won’t want substitution of their expensive biologic with more affordable biosimilar drugs, on the ground of patient safety issues related to immunogenicity, though its instances are rather uncommon.

Some key players in biosimilar drug development:

Having deliberated on the core subject of this article, let me now very briefly name the major players in biosimilar drug development, both in the developed world, and also in India.

The first biosimilar drug was approved by the US-FDA in 2006, and the product was Omnitrope (somatropin) of Novartis (Sandoz). It was the same in the European Union (EU), as well. Subsequently, many other companies reportedly expressed interest in this field, across the globe, including Pfizer, Merck, Johnson and Johnson, Amgen, AbbVie, Hospira, AstraZeneca and Teva, among many others.

Similarly, in India, the major players in this field include, Biocon, Sun Pharma, Shantha Biotech, Dr. Reddy’s Lab, Zydus Cadila, Panacea Biotech and Reliance Life Sciences.

As featured on the Amgen website, given the complexity and cost of development and manufacturing, biosimilars are expected to be more affordable therapeutic options, but are not expected to generate the same level of cost savings as generics. This is because, a biosimilar will cost US$100 to US$200 million and take eight to ten years to develop. Whereas, a small molecule generic will cost US$1 to US$5 million and take three to five years to develop.

The market:

According to the 2017 report titled “Biosimilar Market: Global Industry Analysis, Trends, Market Size & Forecasts to 2023” of Research and Markets, the market size of the global biosimilar market was valued over US$ 2.5 billion during 2014, and it surpassed US$ 3.30 billion during 2016. The global biosimilar market is projected to surpass US$ 10.50 billion by 2023, growing with a CAGR between 25.0 percent and 26.0 percent from 2017 to 2023.

According to this report, gradually increasing awareness, doctors’ confidence and the lower drug cost are expected to boost the demand and drive the growth of the global biosimilar market during the forecast period. Segments related to diabetes medicine and oncology are expected to attain faster growth during the forecast period. Patent expiry of several blockbuster drugs is a major basic factor for growth of the global biosimilar market, as it may encourage the smaller manufacturers to consider producing such biologic drugs in those segments.

Conclusion:

Biosimilar drugs are expected to benefit especially many of those patients who can’t afford high cost biologic medicines offering better treatment outcomes than conventional drugs, in the longer term. These drugs are now being used to effectively manage and treat many chronic and life-threatening illnesses, such cardiac conditions, diabetes, rheumatoid arthritis, psoriasis, multiple sclerosis, Crohn’s disease, HIV/AIDS and cancer.

However, improving patient access to high quality biosimilar drugs, at an affordable price, with increasing competition, could be a challenge, as two key barriers are envisaged to attain this goal. Overcoming these meaningfully, I reckon, will involve choosing thoughtfully a middle path, creating a win-win situation, both for the patients, as well as the industry.

Adequate competition in the biologic drug market is essential – not only among high-priced original biologic brands and biosimilars, but also between biosimilar drugs. This is so important to increase patient access to biologic drugs, in general, across the world, including India.

The current situation demands a sense of urgency in searching for a middle path, which may be created either through a legal framework, or any other effective means as would deem fair and appropriate, without compromising with patient safety, at least, from where it is today.

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?
