Meeting India’s Unmet Biologic Drug Needs Some Global Synergy Evident – But Patients Need More

Posted on by

Many reports have vindicated the rapidly growing importance of biologic drugs in the treatment of a wide range of complex ailments. These include autoimmune diseases, cancers, hormonal irregularities, anemia, and to prevent various diseases such as vaccines, have drawn healthcare experts’ attention globally.

As defined by experts, Biologics are larger, more complex molecules compared to traditional small molecule pharmaceutical drugs. Unlike traditional pharmaceuticals, they require some components from a living organism to be manufactured.

The critical importance of biologic drugs lies in their ability to provide innovative treatment options, address unmet medical needs, and significantly impact patient outcomes in various disease areas. Towards this endeavor, a clear pathway for focused initiatives is warranted, especially in countries like India.

This article will explore this domain to get a sense of how much and how fast the country is progressing in this space, having huge healthcare significance, for all. Let me start with a quick recap on the areas of seminal importance of biologic drugs – to help all to be on the same page – as I start this deliberation.

The critical importance of biologic drugs:

The critical importance of biologic drugs, I reckon, lies in their unique properties and therapeutic potential:

Targeted Therapies: Designed to interact with specific molecules or receptors in the body, allowing for targeted treatment. This specificity can enhance the efficacy of the drug while reducing potential side effects on healthy cells and tissues.

Novel Treatment Options: Offer novel treatment options for diseases that were previously difficult to manage or had limited treatment options. They have revolutionized the management of conditions such as rheumatoid arthritis, psoriasis, multiple sclerosis, and certain types of cancer.

Personalized Medicine: Paving the way for personalized medicine, as it can be tailored to individual patients based on factors like genetic profiles or specific disease characteristics. This approach allows for more precise and effective treatment strategies.

Disease Modification: Unlike some traditional drugs that primarily alleviate symptoms, biologics can often modify the underlying disease process. They can target specific pathways or molecules involved in disease progression, potentially leading to long-term benefits and improved outcomes.

Improved Quality of Life: Has the potential to significantly improve the quality of life for patients living with chronic or debilitating conditions. By effectively managing symptoms and slowing disease progression, they can reduce pain, disability, and the need for other interventions.

It is important to note that biologic drugs are complex to manufacture, often require specialized infrastructure, and can be costly. No wonder why the India specific research paper - published on January 18, 2023 commented: “Although various biologic drugs are already available, they are still not within reach of the common person due to financial constraints.”  This prompts me to explore with examples some of the key issues that Indian patients confront while meeting this health need.

Patient access to original biologic drugs in India faces several key barriers:

Patient access to original biologic drugs in India faces several key barriers, including: 

1. Cost and Affordability:

- Trastuzumab (Herceptin): The cost of a single course of Herceptin, used in the treatment of breast cancer, can range from several lakhs to crores of rupees, making it financially burdensome for many patients in India.

- Eculizumab (Soliris): Eculizumab, used in the treatment of rare blood disorders, can cost several lakhs of rupees per month, making it unaffordable for most patients.

2. Limited Healthcare Coverage:

- Many health insurance policies in India have limitations or restrictions on coverage for expensive biologic drugs, requiring patients to bear a significant portion of the cost out of pocket.

- Some government-funded healthcare schemes, such as the Pradhan Mantri Jan Arogya Yojana (PMJAY), may have restrictions on coverage for expensive biologic therapies, limiting patient access.

3. Regulatory Barriers:

- The approval process for biosimilar versions of original biologic drugs could face delays in India. For example, the biosimilar version of Trastuzumab (Herceptin) faced delays in obtaining regulatory clearance, resulting in delayed patient access to more affordable alternatives.

- The regulatory requirements for original biologic drugs can be complex and time-consuming, leading to delays in drug approvals and subsequent patient access.

4. Limited Local Manufacturing:

- Drugs like Bevacizumab (Avastin) and Adalimumab (Humira) used in India are often imported, leading to supply chain challenges and potential delays in availability.

- Limited local manufacturing of certain original biologic drugs can result in dependence on imported versions, leading to potential pricing issues and supply disruptions.

5. Physician Awareness and Education:

- Some physicians may have limited awareness or familiarity with prescribing guidelines and clinical benefits of certain original biologic drugs. This can result in underutilization or hesitation in prescribing these therapies.

- Lack of specific training and education programs for physicians regarding the latest advancements in original biologic drugs can impact their knowledge and confidence in prescribing them.

6. Patient Education and Understanding:

- Patients may have limited knowledge about the availability and benefits of original biologic drugs. For instance, patients with chronic diseases like rheumatoid arthritis may not be aware of the benefits of newer biologic treatments over traditional therapies.

- Lack of patient education about the appropriate use and potential side effects of original biologic drugs can lead to hesitancy or misconceptions among patients, affecting their willingness to pursue these therapies.

These specific examples illustrate how cost, limited healthcare coverage, regulatory barriers, limited local manufacturing, physician awareness, and patient education can act as barriers to patient access to original biologic drugs in India.

Healthcare impact of inadequate access and availability of biologic drugs in India:

The inadequate access and availability of biologic drugs in India can have several significant healthcare impacts: 

Suboptimal Disease Management: Biologic drugs often provide highly effective and targeted treatments for complex diseases such as cancer, autoimmune disorders, and rare genetic conditions. The lack of access to these therapies can result in suboptimal disease management, leading to poorer patient outcomes, increased disease progression, and reduced quality of life for affected individuals.

Delayed or Incomplete Treatment: Inadequate access to biologic drugs can result in delays or interruptions in treatment. For chronic or progressive diseases, timely initiation and consistent use of these therapies are critical. Delayed or incomplete treatment can compromise the effectiveness of interventions, leading to prolonged disease activity, exacerbation of symptoms, and potential irreversible damage in some cases.

Increased Healthcare Burden: Without access to appropriate biologic therapies, patients may require more frequent hospitalizations, emergency room visits, or other healthcare interventions to manage their conditions. This can place an additional burden on healthcare systems, leading to increased healthcare costs and strain on resources.

Reduced Treatment Options: Biologic drugs often represent the most advanced and effective treatments available for certain diseases. Inadequate access to these therapies limits treatment options for patients, forcing them to rely on less effective or outdated treatments. This restricts the ability of healthcare providers to offer the best available care to patients, potentially leading to compromised treatment outcomes.

Health Inequity: Inadequate access to biologic drugs can exacerbate health inequities in India. Patients from lower socioeconomic backgrounds or those without sufficient insurance coverage may face greater barriers to accessing these expensive therapies. This can result in disparities in healthcare outcomes, with some individuals being unable to afford or access the best available treatments for their conditions.

Impact on Research and Innovation: Inadequate access to biologic drugs can hinder clinical research and innovation in India. Limited availability may reduce opportunities for conducting clinical trials and studying the effectiveness of these therapies in the local population. This, in turn, can hamper the development of new treatments and advancements in healthcare.

Addressing the inadequate access and availability of biologic drugs is crucial to ensure equitable healthcare outcomes, optimize disease management, and reduce the burden of complex diseases in India.  

Increasing need for biosimilar drugs in India and issues involved:

From the above perspective, increasing the availability of biosimilar drugs in India is crucial. Fostering competition may improve affordability. Thereby, it would increase access to essential therapies – bridging treatment gaps, disease management, healthcare system sustainability and foster market competition and innovation.

However, it can ensure that patients receive appropriate and effective treatments while addressing the healthcare challenges faced by a diverse population, only when some key barriers created for biosimilar drug entry, besides patent thickets, are also adequately addressed. One such way is creating a global synergy in this space by collaborating with MNC pharma – having deep pockets and other requisite wherewithal.

Some global synergy is evident in this critical healthcare space:

The good news in this space has started flowing. There have been several collaborations between multinational pharmaceutical companies (MNCs) and domestic Indian drug companies to develop even high potential interchangeable biosimilar drugs in India. Here are a few examples:

- Biocon and Mylan: Biocon has collaborated with Mylan, a global pharmaceutical company, to develop and market biosimilar products. This collaboration has resulted in the development and approval of biosimilar drugs such as Trastuzumab (Herceptin) and Adalimumab (Humira) in India. 

- Dr. Reddy’s Laboratories and Merck: Dr. Reddy’s Laboratories, an Indian multinational pharmaceutical company, entered into a collaboration with Merck & Co., a global pharmaceutical company, to develop biosimilar versions of biologic drugs. This collaboration has resulted in the development and launch of biosimilars such as Pegfilgrastim (Neulasta) and Rituximab (Rituxan) in India.

- Cadila Healthcare and Novartis: Cadila Healthcare, an Indian pharmaceutical company, collaborated with Novartis, a multinational pharmaceutical company, to develop and manufacture biosimilars. This collaboration has resulted in the development of biosimilar drugs such as Rituximab (Ritucad) and Bevacizumab (Bevatas) in India.

These are just a few examples of collaborations between MNCs and Indian drug companies in the field of interchangeable biologic drugs. The landscape of collaborations and partnerships in this area is dynamic, and there may be more ongoing collaborations between companies to develop and commercialize biosimilars in India.

Conclusion:

Overall, patient access to biosimilar drugs in India is crucial for ensuring affordable and comprehensive healthcare, improving patient outcomes, and promoting a competitive pharmaceutical market. It helps address the challenges of access and affordability of biologic drugs, ultimately benefiting the well-being of patients across the country – promoting healthcare equity, and the sustainability of the healthcare system in the country. But patients need more…much more.

Spirit Behind Drug Patent Grant: Secondary Patents: Impact on Drug Access

Posted on by

For more effective treatment against existing diseases, besides combating new or a more complicated form of existing ailments with precision, drug innovation is absolutely necessary and on an ongoing basis. This makes innovative drugs so important for the population, globally.

Besides academia, the pharma industry has remained in the forefront of the search for new drugs, for so long. What makes this process so crucial is, cheaper generic drugs flow from the innovative drugs, post market exclusivity period, which together form the bedrock of the pharma industry’s business model. Consequently, a robust patent protection for the new molecular entities, not only enable the drug innovators to make a reasonably good profit, but also encourage them to keep this virtuous circle moving, faster.

Although, the drug patents are granted for 20 years, after obtaining marketing approval from the respective drug regulators, a time period - ranging between 7 and 12 years, is available to the company to realize its maximum commercial benefits. Thereafter, the patent expires, paving the way of market entry of cheaper generic equivalents to make the drug accessible to a larger population. This is the playbook, which deserves to be accepted and respected by all, both in the letter and spirit.

Currently, the narrative has started changing, apparently, repudiating the spirit behind the grant of new drug patents, especially with the entry of a number of expensive, large molecule biopharmaceutical drugs. After obtaining a fixed-term market exclusivity, more intricate legal measures are being taken to extend the fixed-term market monopoly for an unknown period, delaying market entry of cheaper biosimilar equivalents, post patent expiry, as long as possible.

In this milieu, India appears to be the only country in the world, where the country’s ‘Patents Act’ provides enough safeguard to blunt those legal tools, effectively, to protect patients’ health interest. Quite expectedly, this new narrative of the drug innovators is yielding the best return in the Eldorado of the pharma world – the Unites States. It is also no secret that US vehemently opposes several provisions of the Indian Patents Act 2005, under pressure from the most powerful pharma lobby group, as many believe.

Using the spirit behind drug patent protection as the backdrop, I shall dwell in this article, how this so precious spirit is gradually losing its basic purpose, especially for blockbuster biopharma drugs. Is the key intent behind sacrificing the spirit behind drug patent grant to keep their brands money spinners and big – even after expiry of original patent – as long as possible – at the cost of patients’ health interest?

Despite the original patent expiry, biggest biologic drugs remain big:

The fact that original patent expiries have done little to halt sales of some of the industry’s biggest products – mostly biologic drugs, was clearly elucidated in an  Evaluate Pharma article – “Biopharma’s biggest sellers – the oldies that just keep giving,” published on August 14, 2019. This gets vindicated, as we look at the ‘top ten pharma brands with biggest lifetime sales – from launch to 2018’, in the following Table I:

Product Company Launch year USD Billion
1. Lipitor Pfizer 1997 164.43
2 Humira AbbVie 2003 136.55
3. Rituxan Genentech/Biogen 1997 111.50
4. Enbrel Amgen 1998 108.16
5. Epogen Amgen 1988 107.90
6. Advair GSK 1998 104.20
7. Remicade Janssen 1998   98.00
8. Zantac GSK 1981   97.42
9. Plavix Sanofi/BMS 1998   90.63
10. Herceptin Genentech/Roche 1998   87.97

(Adapted from Evaluate Pharma data of August 14, 2019)

The point to take note of:

The point worth noting here, with the exception of Advair, Zantac, Lipitor and Plavix, all others – among the top ten brands, are biologic drugs. Moreover, what is most striking in the Table I, despite the expiry of the original patents, a large number of biologic brands were able to expand their sales, pretty impressively, for well over two decades. As we shall see later, this situation is expected to continue, at least, till 2024.  As the Evaluate Pharma article states, for various reasons, these multibillion dollar brands have been able to avoid the expected post patent expiry ‘onslaught from biosimilars in the key US market’, which is incidentally the most valuable pharma market in the world.

One of the key reasons that helps delaying cheaper biosimilar drug entry expanding patient access, is a crafty strategic measure adopted by these companies through the creation of a Patent Thicket with secondary patents. As I discussed in this Blog on April 22, 2019, this is a crafty way of ‘evergreening’ patent term beyond 20 years, legally. Whether such measures conform to the spirit of granting 20 years product patent, becomes a moral question, or an issue of probity for the concerned companies, at the most. Be that as it may, a concern over this situation has been raised in many countries, including the United States.

Barrier of secondary patents: 

Biosimilar drug developers continue facing multiple non-financial challenges, such as, scientific, regulatory, pricing. I have already discussed some of these barriers in this blog on July 31, 2017. Instead, I shall focus in this article, with greater detail, on the intricate and a well-woven net of secondary patents. However,before delving into this area, it will be worthwhile to have a quick recap on the basic differences between original patents and secondary patents.

According to WIPO, “Patents on active ingredients are referred to as primary patents. In later phases of the drug development, patents are filed on other aspects of active ingredients such as different dosage forms, formulations, production methods etc. These types of patents are referred to as secondary patents.”

Another excellent paper, authored by two distinguished researchers from Columbia University and LSE, makes some important points on this subject. It says, secondary patents have become increasingly important to the pharma industry, especially in the U.S. and Europe over the past three decades. The basic purpose of ‘taking out multiple patents on different aspects of a drug in order to cordon off competitors is now standard practice in the pharmaceutical industry.’ As the authors further said, this is primarily because: ‘Secondary patents can protect market shares by extending periods of exclusivity beyond the dates in which patent protection would otherwise lapse.’

Interestingly. devising patent strategies to extend periods of market exclusivity is generally considered in the industry, as a key component of ‘product life cycle management,’ – not by the marketing whiz kids, but by astute patent attorneys. Nevertheless, as the paper articulates, critics of this practice often use the more pejorative – evergreening, to describe it.

Examples of impact of secondary patents:

Many research papers suggest, besides scientific complexity in biosimilar drug development being a key reason for their delayed market entry, secondary patents are even tougher barriers for the same. This was brought to light a few years ago in a ‘Review Article’ – ‘The Economics of Biosimilars’, published in the September/October 2013 issue of American Health & Drug Benefits.

Some of the key points made on this issue include,AbbVie plan to defend Humira (adalimumab) with more than 200 secondary patents, Merck’s giving up its biosimilar project on Enbrel when Amgen got its expanded patent life. There are many other such instances.

Its effect would last longer: 

Experts believe, the effect of creating a strong secondary patent shield around blockbuster biologic would last much longer. As the above Evaluate Pharma article underscores: ‘This ability to fend off biosimilar competition is one of the reasons Humira is set to snatch Lipitor’s crown next year as the industry’s most successful drug.’

The Table II below that lists ‘top 10 pharma brands from their respective launch date, including estimated forecast till 2024’, vindicates its long-lasting impact:

Product Company Launch year USD Billion
1. Humira AbbVie 2003 240.05
2 Lipitor Pfizer 1997 180.19
3. Enbrel Amgen 1998 139.83
4. Rituxan Genentech/Biogen 1997 136.07
5. Revlimid Celgene 2008 123.64
6. Remicade Janssen 1998 117.20
7. Epogen Amgen 1988 115.87
8. Herceptin Genentech/Roche 1998 114.89
9. Avastin Genentech/Roche 2004 114.27
10. Advair GSK 1998 113.61

(Adapted from Evaluate Pharma data of August 14, 2019)

Although, Zantac and Plavix no longer feature in this table, one drug that leapfrogged much of the competition to become one of the industry’s biggest future bestsellers is Revlimid. The projected sales of the drug over the next six years will actually outstrip its sales to date. However, much of this is dependent on whether generic competition will arrive ahead of Revlimid’s 2022 patent expiry, the paper indicated.

Concern expressed even in the US for the delay in biosimilar market entry:

Many big spending countries on health care, such as the United States expected that timely biosimilar drug entry will help contain health expenditure significantly. However, the article published in the Fierce Pharma on August 29, 2019, raises an alarm, but with a hope for the future. It says: “It’s no secret biosimilars haven’t made a big dent in U.S. drug spending. Some experts have even said it’s time to give up on copycat biologic.”

This hope gets resonated with what, ‘the former US-FDA commissioner Scott Gottlieb argues’. He feels, ‘It’s too soon for that’, while ‘calling on Congress to bolster the budding market.’ However, in my personal view, this will remain a difficult proposition to implement, as biologic drug players will continue using their relatively new, but powerful weapon of filing a number of complex ‘secondary patents.’ These will help extend the market exclusivity period of their respective brands, much beyond the original patent grant period, unless a counter legal measures are taken by the lawmakers of various countries, including the United States. But, India is an exception in this regard.

Indian patent law doesn’t encourage ‘secondary patents’:

The good news is, Indian Patent Act 2005, doesn’t encourage ‘secondary patent.’ This is because, section 3 (d) of the Indian Patent Act 2005 limits grant of ‘secondary pharmaceutical patents.’ An interesting study reported on February 08, 2018, discussed about 1,700 rejections for pharma patents at the IPO spanning over the last decade. But, there is a huge scope for improvement in this area.

Which is why, the not so good news is under-utilization of the same section 3.d by the Indian Patent Office (IPO), as are being voiced in many reports. One such paper of April 25, 2018 highlighted,72 per cent of pharma patent grants are secondary patents. These were granted for marginal improvements over previously known drugs for which primary patents exist. That said, despite such reported lapses, blocking of some crucial secondary patent grant has benefited a large number of patient population of India.

Blocking secondary patent grant has helped India immensely:

While US recognizes secondary patents, blocking secondary patent grant, especially for biologic drugs has helped Indian patients immensely, with expanded access to those medicines. This was also captured in the above study. Besides the classic case of Novartis losing its secondary patent challenge for Glivec in the Supreme Court of India in 2013, several other examples of secondary patent rejection are also available. This includes, among others, Glivec of Novartis and the world’s top selling drug for several years – Humira of AbbVie.Against a month’s therapy cost of ₹1,6o, ooo for Glivec in the US, its Indian biosimilar version costs for the same period ₹11,100. Similarly, while the treatment cost with Humira in the US is ₹85,000, the same with its biosimilar version in India is ₹ 13,500, as the above study finds.

Conclusion:

The core purpose of drug innovation, as widely touted by the R&D-based drug companies, is meeting the unmet needs of patients in the battles against diseases. Thus, drug innovation of this genre must not just be encouraged, but also be adequately protected and rewarded by granting product monopoly for a 20-year period from the date of the original patent grant. Curiously, piggybacking on this basic spirit behind the drug patent grant, pharma lobby groups are now vocal on their demand for giving similar treatment to secondary patents on various molecules. The tone of demand gets shriller when it comes to section 3. d of the Indian Patents Act, which doesn’t allow such ‘evergreening’ through secondary patents.

Thus, the key question that surfaces, while the original patent grant for innovative drugs help meeting unmet needs of some patients, whose unmet needs would a secondary patent grant meet, except making the concerned company richer? Further, for highly expensive biologic drugs, delayed market entry of cheaper biosimilars in that process, would deny their expanded access – failing to meet the unmet needs of scores of others.

Hopefully, India won’t give in to pressure of multinational pharma lobby groups, channeled through various powerful overseas government entities. At the same time, I hope, the government in power at the Eldorado of the pharma industry, will consider giving a fair chance of market entry to cheaper biosimilars, including those from India, to also grow their business globally, but in a win-win way.

The key objective of all stakeholders involved in this process, should be to uphold the basic spirit behind drug patent grant. It may even call for challenging the core intent behind secondary patent applications, the world over, that deny quicker market entry for cheaper biosimilars, sans heavy litigation expenses. This will help expand access to cheaper biologic medicines to all those who can’t afford those, otherwise.

Pharma To Facilitate Self-Managing Chronic Diseases For Better Outcomes?

Posted on by
Reply

“India’s burden of non-communicable disease (NCD) is escalating, but still the country does not have sufficiently detailed data on NCDs for research and policy purposes.” This was captured in a recent study, titled “India’s escalating burden of non-communicable diseases,” published in The Lancet Global Health on October 03, 2018. Thus, many experts are pondering, how to contain this menace and lower the disease burden of NCDs, in this situation. One of the ways to address this issue is exploring some unconventional ways.

As several studies have established, improving ‘self-management’ of chronic diseases by patients, after proper diagnosis and a treatment plan being in place, is one of the pillars to lower the disease burden. One such study is titled, ‘Patients’ knowledge of their chronic disease,’ appeared on June 2013 – Vol 42 (6) issue in the journal of afp – Australian Family Physician. The paper highlights that effective tools, policies and other measures to help self-management, would facilitate the process. These arecritical not just for better outcomes, but also to reduce the overall treatment cost.

In a similar context, another recent article, titled ‘Why Apps for Managing Chronic Disease Haven’t Been Widely Used, and How to Fix It,’ published in The Harvard Business Review (HBR) on April 04, 2018 made an interesting observation. The authors wondered: “In an era where nearly, every consumer good and service — from books and groceries to babysitting and shared rides — can be purchased through an electronic transaction on a mobile device, it seems reasonable to think that more and more of our health care can also be managed using apps on mobile devices.”

This article will dwell in this area, based on several interesting and credible research findings. Nevertheless, to give a proper perspective, I shall start with a brief outline on the incidence of chronic diseases in India.

Increasing incidence of chronic diseases in India:

There are several recent reports confirming the ascending trend of non-infectious chronic diseases in India, two of which are as follows:

The National Health profile 2018, published by the Ministry of Health also records that between 1990 and 2016 the disease burden due to:

  • Communicable, maternal, neonatal, and nutritional diseases, as measured using Disability-adjusted life years (DALYs), dropped from 61 per cent to 33 per cent.
  • Noncommunicable diseases increased from 30 per cent to 55 per cent.
  • The epidemiological transition varies widely among Indian states: 48 percent to 75 percent for non-communicable diseases, 14 percent to 43 percent related to infectious and associated diseases; and 9 percent to 14 percent associated with injuries.

Alongside, the above article of The Lancet Global Health also underscores the following takeaways from its comprehensive analyses of NCDs in the Indian situation:

  • The three leading causes of mortality—cardiovascular diseases, respiratory diseases, and diabetes.
  • In absolute terms, these three diseases together kill around 4 million Indians annually (as in 2016).
  • Most of these deaths are premature, occurring among Indians aged 30–70 years, representing some of the world’s largest health losses, with enormous policy ramifications.
  • India’s Ministry of Health and Family Welfare is making efforts to establish policies and intervention strategies for prevention and control NCDs. For example, the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke, launched in 2010, and the National Program for Health Care of Elderly, launched in 2010–11, the article noted.

As none of the measures taken so far could create an appreciable impact, India needs to come up with a major intervention to tackle this escalating health issue, the article concluded. In my view, optimal use of modern technology in the self-management of such virtually lifelong diseases, can be a great enabler for patients to bring down the disease treatment and management cost, significantly. Let me hasten to add again, the question of self-management comes only after a proper medical diagnosis and a prescribed treatment plan for the same being in place.

The key benefits of self-management and the unmet need:

The key benefits of effective self-management of chronic diseases are many. However, the following four clearly stands out:

  • Improves Patients’ quality of life significantly.
  • Arrests progression of the ailment – containing associated disease related complications.
  • Substantially reduces the interval and number of follow-up visits with doctors.
  • Thus, reduces the disease burden appreciably.

Curiously, most traditional pharma companies are yet to take any major step to address, at least, the above four critical areas. They don’t seem to go beyond the conventional methods of disease related advices. Whereas, the crucial need to fetch a behavioral change in patients for participative self-management of NCDs, keeps lingering.

A number of research studies have also confirmed that ‘mobile health applications are promising tools for improving outcomes in patients suffering from various chronic conditions.’ One of these studies titled, ‘Smartphone app in self-management of chronic low back pain: a randomized controlled trial’, was published in the November 27, 2018 issue of the European Spine Journal.

Sensing an unmet need in this area, besides a large number of brilliant tech startups, many large and pure technology companies, such as Apple and Google have already entered this fray.

 A recent example:

Let me cite a recent example to drive home the above point. On December 12, 2018, CNBC featured an article carrying the headline ‘Apple now has dozens of doctors on staff, showing it’s serious about health tech.’ Some of the key points of this article are as follows:

  • The number of doctors on staff is an indication that Apple is serious about helping customers manage diseases, and not just wellness or fitness.
  • Doctors can also help Apple guide the medical community on how to use Apple’s new health technologies and to deflect criticism and also to win approval among doctors who fear liability and are already overburdened by technology.
  • Many of these doctors are also still continuing to see patients. That might also give Apple an edge by emphasizing the patient experience.

This example demonstrates how detail are the plans of these tech companies for gaining a firm foothold in the healthcare space.

‘Effectiveness’ and ‘future scope’ of self-management of diseases:

The article titled, ‘Self-Management: A Comprehensive Approach to Management of Chronic Conditions,’ featured in the August 2014 edition of the American Journal of Public Health (AJPH) reiterated some important points. It established the relevance, future scope and effectiveness of self-management of chronic diseases, as follows:

  • As chronic conditions emerge as a major public health concern, self-management will continue to grow as a crucial approach to managing these conditions, preventing illness and promoting wellness.
  • Chronic disease conditions are generally slow in their progression and long in their duration. Thus, self-management can offer those living with these conditions, a means to maintain or even improve their capacity to live well, over the course of their lives.
  • Self-management intervention programs that address specific diseases are showing success across multiple chronic conditions.
  • These programs have particular value that represents an amalgamation of the goals of the patient, family, community, and the clinician with everyone working in partnership to best manage the individual’s illness while facilitating comprehensive care.
  • Self-management reaches beyond traditional illness management by incorporating the larger concept of prevention by emphasizing the notion that those who are chronically ill still have a need for preventive interventions to promote wellness and mitigate the further deterioration of health.
  • If one considers the nature of self-management in all its elements and practical characteristics, it is not only a logical approach to health and health care, but also an optimal way to address chronic conditions as a major issue in public health.

Inducing a behavioral change in chronic disorders with health apps:

For effective self-management of chronic diseases, there is a need to neutralize the negative influence of the individual’s behavioral traits. Research studies have also established that behavior-change-focused interventions play an important role in this effort.

However, not all patients take adequate care for such changes to take place. While the treating doctor may play an important role of a coach in this area, in reality, they usually don’t find enough time to spend on each patient with NCDs. The McKinsey & Company’s publication titled, ‘Changing patient behavior: the next frontier in health care value,’ also reiterates that to address the rising cost of chronic conditions, health systems must find effective ways to get people to adopt healthier behaviors.

As I mentioned before, this space has attracted active interest of many tech players in business expansion. More evidence-based health apps are being introduced to help drive patient-behavior change for effective self-management of chronic diseases. There are reported surveys on weight management aided by health apps, where ‘ninety-six percent of respondents agreed or strongly agreed that using a diet or nutrition app helped drive positive behavior change and healthy eating habits.’

In my article, titled ‘Prescription Digital Therapy Now A Reality,’ published in this blog on May 07, 2018, I mentioned that in September 2017, the first USFDA-cleared mobile app has been made available to patients. The app has both safety and efficacy label to help treat patients with ‘Substance Use Disorder’. Studies have established that it is two-times more effective than conventional in person therapy sessions.

More recently, in September 2018, Apple’s smart-watch version 4 included a US-FDA cleared electrocardiogram (ECG), officially classifying it as a medical device capable of alerting its user to abnormal heart rhythms. In the same context, US-FDA Commissioner Scott Gottlieb, M.D., said that digital advances, creating a new technological paradigm of health tools and health apps., are empowering consumers to take better informed decisions on their medical care and healthy living.

Conclusion:

It has been well-demonstrated by research studies that evidence-based health-apps for self-managing chronic diseases improve outcomes, remarkably. Consequently, this has triggered some critical activities by purely tech companies in the health care space, even in India. The primary driver being a strong consideration of this segment as an opportunity area to meet an unmet need, where most pharma players don’t seem to be doing enough, as on date.

Before it gets too late, there appears a need to take a serious note of this shifting paradigm. The awareness of which should then play a critical role in developing marketing strategies for brands used in NCDs. Otherwise, non-pharma tech companies will eventually dominate this segment, armed with a different genre of technological prowess that they possess.

The article titled, “Evidence-Based mHealth Chronic Disease Mobile App Intervention Design: Development of a Framework,” published inJan-Mar 2016 edition of the Journal of JPMIR Research Protocols, epitomizes it succinctly:

“Mobile health technology creates a shift in the paradigm of chronic disease management. It offers new possibilities to engage patients in self-management of their chronic diseases in ways that did not exist in the past. To maximize the potential of mHealth requires the integration of research and expertise from multiple disciplines including clinical, behavioral, data analytics, and technology to achieve patient engagement and health outcomes. This paradigm shift also triggers a need for new approaches to designing clinical and behavioral support for chronic disease management that can be implemented through existing health care services and programs.”

These developments send a strong signal for pharma to facilitate self-managing chronic diseases, soon enough, for better patient outcomes and, in tandem, creating a win-win situation for both.

“Meeting Unmet Needs of Patients”: A New Direction

Posted on by

The much-hyped phrase of the global pharma majors – ‘meeting unmet needs of patients’, is very often used to create an aura around newer patented drugs of all kinds, from original to banal, including evergreen varieties such as:

Evergreen Drug/Brand Medical Condition Original Drug/Brand
Levocetirizine (Vozet) Allergies Cetirizine (Zyrtec)
Escitalopram (Lexapro) Depression Citalopram (Celexa)
Esomeprazole (Nexium) Acid reflux Omeprazole (Prilosec)
Desloratadine (Clarinex) Allergies Loratadine (Claritan)
Pregabalin (Lyrica) Seizures Gabapentin (Neurotonin)

I do not have any terrible issue with this usage, as many stakeholders, including various governments, have already started differentiating between the ‘Chalk’ and the ‘Cheese’ kinds of patented products and contemplating future course of action, accordingly. The recent development in South Africa is one such example.

That said, there is now a greater need to ponder over the much bigger picture in the same context and direction, which would improve predictability of treatment outcomes by manifold. Simultaneously, such R&D initiatives would help reducing the overall cost, especially for dreaded diseases like cancer, mainly through highly targeted drugs and consequently avoiding the risk and associated wastage, as often happens with the prevailing ‘trial and error’ therapy approach, thereby benefitting the patients immensely. This is mainly because no drug is 100 percent effective with inconsequential side-effects for all patients of any disease type.

Genetics and Genomics Science made it possible:

With already acquired knowledge in genetics, genomics and genome sequencing capability, it is now possible to precisely predict a person’s susceptibility to various disease types and proactively working out measures to help either avoiding ailments, such as, non-infectious life threatening and chronic diseases altogether, if not, making their treatment more predictable and less expensive, as stated above.

If organized efforts are made to extend the application and benefits of this science to a larger section of population, those R&D initiatives can really be construed, unquestionably, as ‘meeting unmet needs of the patients’, just as ‘first in kind’ category of innovative drugs are recognized by the scientific community and the civil society as a whole.

A treatment revolution in the offing:

Expectations are rapidly building up that evolving genetics and genomics science based technological know-how would ultimately revolutionize the practice of medicine ushering-in the pathway of personalized medicine for a large number of patients.

Definition: 

A report from the Tufts Center for the Study of Drug Development defines personalized medicine as “Tailoring of medical treatment and delivery of health care to individual characteristics of each patient, including their genetic, molecular, imaging and other personal determinants. Using this approach has the potential to speed accurate diagnosis, decrease side effects, and increase the likelihood that a medicine will work for an individual patient.”

The aim: 

The aim of personalized medicine is, therefore, to make a perfect fit between the drug and the patient. It is worth noting that genotyping is currently not a part of clinically accepted routine. However, it is expected to acquire this status in the western world, shortly.

To give a very quick example, genetic differences within individuals determine how their bodies react to drugs such as Warfarin – a blood thinner taken to prevent clotting. It is of utmost importance to get the dosing right, as more of the drug will cause bleeding and less of it will not have any therapeutic effect.

In the field of cancer, genetic tests are now being done by some oncologists to determine which patients will be benefited most; say with Herceptin, in the treatment of breast cancer.

Thus, with personalized medicine the health of a patient will be managed based on personal characteristics of the individual, including height, weight, diet, age, sex etc. instead of defined “standards of care”, based on averaging response across a patient group. Pharmacogenomics tests like, sequencing of human genome will determine a patient’s likely response to drugs.

Disease prevention: 

In addition, such medicines would help identifying individuals prone to serious ailments such as, metabolic, cardiac, endocrine, auto-immune, psychosomatic, including cancer of various types; enabling physicians to take appropriate preventive measures much before disease manifestations and in that process would help containing the overall treatment cost.

Cost of genome sequencing:

Sir John Bell, Professor of Medicine at Oxford University, reportedly said in early December 2012 that personalized medicine for all could soon be a clear possibility, as everybody will be able to have their entire DNA make-up mapped for as little as £100 (Rs.10, 000 approx.).

This estimate seems to be realistic, as the price of genome sequencing has fallen by 100,000-fold in 10 years. This cost is expected to further decline, as genome of any person essentially remains unchanged over time. Thus, this information might become a part of an individual’s medical record allowing the doctors to use it as necessary.

Summary of key advantages: 

To summarize, the expected benefits from personalized medicine, besides very early diagnosis as stated above, are the following:

1. More Accurate Dosing: Instead of dose being decided based on age and body weight of the patients, the physicians may decide and adjust the dose of the medicines based on the genetic profiling of the patients.

2. More Targeted Drugs: It will be possible for the pharmaceutical companies to develop and market drugs for patients with specific genetic profiles. In that process, a drug needs to be tested only on those who are likely to derive benefits from it. This in turn will be able to effectively tailor clinical trials, expediting the process of market launch of these drugs.

3. Improved Healthcare: personalized medicine would enable the physicians to prescribe ‘the right dose of the right medicine the first time for everyone’ without any trial or error approach, resulting in much better overall healthcare.

Current use:

Though these are still the early days, initial usage of personalized medicine is now being reported in many areas, such as:

Genetic analysis of patients dealing with blood clots: Since 2007, the U.S. Food and Drug Administration has been recommending genotyping for all patients being assessed for therapy involving Warfarin.

Colorectal cancer: For colon cancer patients, the biomarker that predicts how a tumor will respond to certain drugs is a protein encoded by the KRAS gene, which can now be determined through a simple test.

Breast cancer: Women with breast tumors can now be effectively screened to determine which receptors their tumor cells contain.

In addition, this approach would also help clinicians to determine which particular therapy is most likely to succeed on which patient.

Present outlook: 

A September 2013 article published in Forbes Magazine titled, “Personalized Medicine May Be Good For Patients But Bad For Drug Companies’ Bottom Line” says, although personalized medicine offers tremendous potential for patients, because of the dual burdens of expensive clinical trials and diminished revenue potential, the concept may become unsustainable in the long term, the attitude of regulators will be critical to drug companies’ willingness to embrace personalized medicine, and to its wider application.

In my view, for greater interest of patients to ‘meet their unmet needs’ global pharma, majors, academics, respective governments and the drug regulators should find a way out in this new direction, sooner.

Indian initiatives:

Some companies, both well known and lesser known, are making collaborative progress, keeping low profile, in the genome sequencing area in India, which will ultimately make expensive treatments, such as cancer, more predictable and simultaneously affordable to many.

The concerns:

While the progress in the field of personalized medicine is quite heartening, some experts have reportedly been sounding a note of caution. They strongly feel that DNA code sequencing brings to light a “very real privacy concerns” of individuals.

The key argument being, if genome sequencing is extended to entire population, individuals and their relatives could then be identified and tracked by matching their DNA with the genome stored in the respective health records. This move, as contemplated by the opponents, could “wipe out privacy” with a significant impact on the society.

A paper published in ‘Scientific American’ dated January 2014, titled “What Fetal Genome Screening Could Mean for Babies and Parents” deliberated that today doctors are closer than ever before to routinely glimpsing the full genetic blueprints of a fetus just months after sperm meets egg. That genomic reconstruction would reveal future disease risk and genetic traits even as early as the first trimester of pregnancy – raising another ethical issue that could hugely impact parents’ decision threshold for deciding to terminate a pregnancy or influencing how they rear their child.

Thus, all these ethical and social issues in the development and usage of personalized medicine must be appropriately addressed under a well deliberated ethical, social, legal and regulatory framework of each country.

Conclusion:

Though in Europe and to some extent in the United States, treatments based on personalized medicine have already been initiated, we are still in a nascent stage for this novel concept to get translated into reality for the benefit of a much wider population across the world.

Lot of grounds may still need to be covered, especially in the realm of medical research and also to work out the regulatory pathways for personalized medicine in healthcare by the pioneers of this great concept and more importantly by effectively addressing the ethical concerns raised on this subject.

If collaborative initiatives are taken jointly by academia, R&D based global pharma majors and medical diagnostic players towards this new direction with a clearer focus and  supported by the law makers, a huge unmet needs of patients will truly be met, giving yet again a fresh impetus to the much hyped phrase “Meeting Unmet Needs of Patients”, though in a refreshingly new direction.
