Improving Patient Access to Biosimilar Drugs: Two Key Barriers

Improving Patient Access to Biosimilar Drugs: Two Key Barriers

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 .....Continue reading….

Rebuilding Pharma Image: A Laudable Mindset – Lacking In Many

Rebuilding Pharma Image: A Laudable Mindset – Lacking In Many

The fierce debate on ethics and compliance related issues in the pharma marketing practices still reverberates, across the globe. One of its key fallout has been ever-increasing negative consumer perception about this sector, sparing a very few companies, if at all. As a result, many key communications of the individual players, including the industry associations specifically targeted to them, are becoming less and less credible, if not ineffective.

Which is why, though pharma as an industry is innovative in offering new medicines, consumers don’t perceive it so. Despite several drug players’ taking important steps towards stakeholder engagement, consumers don’t perceive so. The list goes on and on. I discussed on such consumer perception in my article of June 26, 2017. Hence, won’t further go into that subject, here.

General allegation on the pharma industry continues to remain unchanged, such as the drug industry tries to influence the medical profession, irrespective of whether they write prescription drugs for patients or are engaged in regulatory trial related activities aimed at product marketing.

Let me give an example to illustrate the later part of it, and in the Indian context. On April 26, 2017, it was reported that responding to a joint complaint filed by Mylan and Biocon in 2016, alleging that the Roche Group indulged in “abusive conduct”, the Competition Commission of India (CCI) gave directions for carrying out a detailed investigation on the subject. This probe was initiated to ascertain, whether Roche used its dominant position to maintain its monopoly over the breast cancer drug Trastuzumab, adversely impacting its access to many patients.

Such a scenario, though, undoubtedly disturbing, is very much avoidable. Thus, winning back the fading trust of the consumers in the industry, should be ticked as a top priority by the concerned parties.

In this article, I shall mostly focus on some recent developments related to ethics and compliance issues, mainly in pharma marketing, and with a small overlap on the regulatory and other areas, as and when required to drive home a point.

It shakes the trust base on the medical profession too:

This menace, as it were, though, more intense in India, is neither confined to its shores alone, nor just to the pharma industry, notwithstanding several constituents of big pharma have been implicated in mega bribery scandals in different countries. There doesn’t seem to be much doubt, either, that its impact has apparently shaken the very base of trust even on the medical profession, in general.

Not very long ago, Dr. Samiran Nundy, while holding the positions of Chairman, Department of Surgical Gastroenterology and Organ Transplantation at Sir Ganga Ram Hospital and Editor-in-Chief of the Journal of Current Medicine Research and Practice, reportedly exposed the widespread malpractices of the doctors in India who are taking cuts for referrals and prescribing unnecessary drugs, investigations and procedures for profit.

This practice continues even today, unabated. On June 18, 2017, it was widely reportedin India that Maharashtra Government has decided to form a 3-member committee for suggesting effective ways to check the ‘cut practice’ of doctors. This decision followed a public awareness campaign on this subject, initiated by well-reputed late heart surgeon – Dr. Ramakanta Panda’s Asian Heart Institute, located in Mumbai. The hospital had put up a hoarding saying: ‘No commission. Only honest medical opinion’. The Indian Medical Association opposed the hoarding. But the hospital wrote to Maharashtra medical education minister seeking a legislation to fight this malpractice.

To contain this malady across India, for the sake of patients, Dr. Nundy had then suggested that to begin with, “The Medical Council of India (MCI), currently an exclusive club of doctors, has to be reconstituted. Half the members must be lay people like teachers, social workers and patient groups like the General Medical Council in Britain, where, if a doctor is found to be corrupt, he is booted out by the council.”

This subject continues to remain an open secret, just as pharma marketing malpractices, and remains mostly confined to the formation of various committees.

“Corruption ruins the doctor-patient relationship in India” – a reconfirmation:

“Corruption ruins the doctor-patient relationship in India” - highlighted an articlepublished in the British Medical Journal (BMJ) on 08 May 2014. Its author – David Berger wrote, “Kickbacks and bribes oil every part of the country’s health care machinery and if India’s authorities cannot make improvements, international agencies should act.”

He reiterated, it’s a common complaint, both of the poor and the middle class, that they don’t trust their doctors from the core of hearts. They don’t consider them honest, and live in fear of having no other choice but to consult them, which results in high levels of doctor shopping. David Berger also deliberated on the widespread corruption in the pharmaceutical industry, with doctors bribed to make them prescribe specified drugs.

The article does not fail to mention that many Indian doctors do have huge expertise, are honorable and treat their patients well. However, as a group, doctors generally have a poor reputation.

Until the medical profession together with the pharma industry is prepared to tackle this malady head-on and acknowledge the corrosive effects of medical corruption, the doctor-patient relationship will continue to lie in tatters, the paper says.

Uniform code of ethical pharma marketing practices:

This brings us to the need of a uniform code of ethical pharma marketing practices. Such codes, regardless of whether voluntary or mandatory, are developed to ensure that pharma companies, either individually or collectively, indulge in ethical marketing practices, comply with all related rules and regulations, avoid predominantly self-serving goals and conflict interest with the medical profession, having an adverse impact on patients’ health interest continue reading…

Dawns A New Era: Regenerative Medicine for Degenerative Disease

Dawns A New Era: Regenerative Medicine for Degenerative Disease

Could breakthrough innovation in ‘Regenerative Medicine’ significantly reduce the need of expensive lifelong medications, or even make the use of some important medical devices less relevant, or even help avoiding expensive and risky surgical interventions? The common answer to these critical questions is now getting clearer, in tandem with the rapid progress of the science of ‘Regenerative Medicine.’

On June 13, 2017, Nature Biomedical Engineering published an interesting an articletitled, “3D-printed vascular networks direct therapeutic angiogenesis in ischemia.” In simple words, these 3D-Printed patches are going to usher in a highly innovative way to treat ischemic diseases, in the future. As the researchers highlighted, arterial bypass grafts are currently considered as the gold standard for the treatment of end-stage ischemic disease, though many patients are unable to tolerate the cardiovascular stress of arterial surgery. The researchers found that implantation of 3D-printed grafts containing endothelial-cell-lined lumens, induces spontaneous and geometrically guided generation of collateral circulation in ischemic settings.

In rodent models of hind limb ischemia and myocardial infarction, these scientists successfully demonstrated that the vascular patches rescue perfusion of distal tissues, preventing capillary loss, muscle atrophy and loss of function.

In this article, I shall deliberate on the importance of this discovery, and its overall future implications on a broader perspective.

Regenerative medicine:

Here comes the basic question – What is ‘Regenerative Medicine’?

It is defined as a highly innovative branch of medicine that develops implementable methods to regrow, repair or replace damaged or diseased cells, organs or tissues. According to RegerativeMedicine.net following are illustrations of some conditions or diseases that regenerative medicine has the potential to cure, and what their current state of treatment looks like in in the American perspective:

• Heart valves- 250,000 patients receive heart valves, at a cost of US$27 billion annually
• Heart disease and Stroke- 950,00 people die of heart disease or stroke, at a cost of US$ 351 billion annually
• Diabetes- 17 million patients have diabetes, at a cost of US$ 132 billion annually

I discussed in this blog, the subject of ‘3D Printing in health care’ on January 11, 2016. Hence, won’t dwell on that subject here

Ischemia, and the relevance of the above discovery:

Ischemia, as many would know, is a condition that restricts adequate flow of blood in some parts of our body, which over a period, may narrow, harden or even block the important blood vessels, much often resulting in stroke, heart attack or other related life-threatening vascular disorders....continue reading….
