‘Digiceuticals’: A Force Multiplier to Contain Chronic Diseases

Posted on October 23, 2017 by Tapan Ray

There is a growing need for more effective prevention, treatment or management of many serious Noninfectious Chronic Diseases (NCDs), with greater safety and at a lesser cost. As a major step in this direction, ‘digiceuticals’ or ‘digital therapeutics’ are now drawing heightened interest from the medical and scientific communities.

‘Digiceuticals’ are basically custom made digital software working as drugs. These are presented mostly in the form of user-friendly smartphone apps for various disease conditions – both as stand-alone therapy, or to augment other treatment processes for better outcomes.

Increasing usage of digital technology enabled therapy for a gamut NCDs, prompts me to discuss in this article the relevance, scope, promise, and of course, the rationale behind the same. Its importance swells manifold when the risks of lifelong health hazards that such chronic disorders may pose are factored-in, alongside their overall socioeconomic impact.

Chronic diseases – the invisible global epidemic:

Chronic diseases, such as heart disease, stroke, chronic respiratory disorders and diabetes, including cancer, are by far the leading causes of death and disability worldwide. The World Health Organization (W.H.O) also reiterates that this invisible epidemic is spreading out globally – across every region and pervading all socioeconomic classes.

The mortality, morbidity and disability attributed to chronic diseases, as estimated by the W.H.O, is expected to rise to 73 percent of all deaths and 60 percent of the global burden of disease by 2020. Interestingly, 79 percent of the deaths attributed to chronic disorders occur in the developing countries, such as India.

Can chronic diseases be prevented?

W.H.O also emphasizes that four of the most prominent chronic disorders, namely cardiovascular (CVD), cancer, Chronic Obstructive Pulmonary Diseases (COPD), and Type 2 diabetes – are linked by common and preventable biological risk factors, notably high blood pressure, high blood cholesterol and overweight. Most importantly, these relate to major behavioral risk factors, like unhealthy diet, physical inactivity and tobacco use, among several others.

Awaits a radical change – from “Suppliers Push” to “Consumer Pull”:

In the above perspective, a series of well-integrated action related to several human behavioral factors, could help prevent many NCDs, effectively. A fundamental change in mindset of all concerned is critical to avert the merciless onslaught of this epidemic. This calls for a radical change in the existing process of addressing these disorders – from “Suppliers Push” to “Consumer Pull.”

The January 2017 White Paper titled, “Human-Centric Health: Behavior Change and the Prevention of Non- Communicable Diseases”, published by the World Economic Forum (WEF), drives home this point succinctly, as follows:

“Decreasing the burden of NCDs will require a transformation through which the threat of disease is recognized and addressed. The transformation should move us away from the present state of ‘supplier push’, which emphasizes expensive, capital-intensive, hospital-centric interventions that have so far produced disappointing results, to a system that relies on ‘consumer pull’. A consumer-focused system would recognize the principles of behavioral economics to encourage and enable people to adopt healthier behavior across all aspects of their lives. Individuals would be supported in this effort by a network of critical stakeholders ranging from government to private enterprise, from healthcare providers to payers, from the technology developers to local communities.”

NCDs are triggered by behavioral pattern and lifestyle:

Picking up the thread from here, I shall deliberate now, how the state of the art digital technology-developers are playing a stellar role in this space, with greater precision and more cost-effective way. This is because, many NCDs are triggered by consistent behavioral and lifestyle pattern of an individual. Consequently, continuously monitoring of desired changes in individual behavior, are expected to gradually become the first-line treatment to effectively address these conditions. Several published studies indicate that the process has started rolling, aided by smartphone based sophisticated digital tools – in many cases even without any expensive and lifelong medications.

The May 26, 2016 paper titled, “Clustering of Five Health-Related Behaviors for Chronic Disease Prevention Among Adults, United States, 2013”, captures a cluster of five health-related behaviors for chronic disease prevention as – never smoking, getting regular physical activity, consuming no alcohol or only moderate amounts, maintaining a normal body weight, and obtaining daily sufficient sleep. This article was published by the Centers of disease Control and Prevention of the United States.

Preventing chronic diseases with ‘digiceuticals’:

The April 7, 2017 article captioned, “Can ‘Digital Therapeutics’ Be as Good as Drugs?”, published by the MIT Technology Review, dwells on this area. The paper indicates an emerging belief among technology geeks that ‘digiceuticals’, or digital drugs will become ‘the third phase’ of medicine for many disease conditions, being the successor to the chemical and protein drugs that we have today, but without the billion-dollar cost of bringing one such drug to market. The core idea behind this new concept is to develop software that can improve a person’s health as much as a drug can, but without the same cost and side-effects, the author says.

An innovative new class of medicine:

The term digital therapeutics or ‘digiceuticals’, as many calls these, is considered as an innovative new class of medicine that gives participants access to the world’s most effective behavior therapies, enhanced with smart digital technology, and delivered directly to their front door. These can be used both as a replacing medicine, and also for enhancing efficacy of a medical treatment, as a situation would necessitate.

There doesn’t seem to be any clear-cut difference between these two – digital therapeutics and ‘digiceuticals’. Nonetheless, some do believe that there is a difference – quite akin to prescription medication versus nutritional supplements, with consequential differences in regulatory and other areas. Be that as it may, ‘digiceuticals’ when used for prevention, treatment or effective management of any chronic ailments would require to be scientifically evaluated just as any other drugs, devices and treatment processes.

The future of health care will be App-based:

Another article titled “Digital Therapeutics: The Future of Health Care Will Be App-Based”, published in Forbes on July 24, 2017, highlights how several digital technology companies are now focusing on the development of state of art smartphone app-based digital treatment programs that can be delivered at a massive scale and with a low cost to prevent progression of many debilitating NCDs, for a large population across the world, including India.

‘Digiceuticals’ versus other mobile wellness apps:

Unlike many smartphone based wellness apps to keep a regular tab on daily exercises, heart rates, calorie intakes, breathing, sleep pattern among several others; treatment processes with ‘digiceuticals’ are quite different. These softwares are tailor-made to prevent or treat specific chronic disorders, like diabetes, cardiovascular conditions, COPD, insomnia and chronic depression, to name a few. The trend is fast catching up along with an increasing general realization that the influence of individual behavior and lifestyle pattern is so crucial in the prevention, and also in arresting the progression of many debilitating NCDs.

The current status:

The latest scenario in this area has been well captured in several research studies. One such is the 2017 Report of Grand View Research, Inc., which articulated the following key findings:

The global ‘digiceuticals’ or digital therapeutics market size was estimated at USD1.7 Billion in 2016, which is expected to grow at 21.0 percent CAGR from 2017 to 2025.Diabetes is expected to gain the largest market share due to the increasing global prevalence, fueled by the preventive steps taken to reduce them.

The adoption of digital therapeutics offers a reduction in healthcare cost associated with many NCDs, and are thus being used on an increasing scale. Digital tracking, continuous monitoring of various health parameters, management of physical activity and controlling eating habits are some of the important factors expected to propel the market growth.

Ascending trend of its usage for prevention of a wide range of NCDs would further add to the growth momentum. Patients accounted for the largest market share in the end-user segment owing to user-friendly interface and cost-effective management of many NCDs.

The North American region accounted for the highest revenue owing to technological advancement and health care expenditure to curb rise in a number of chronic diseases.

The Asia Pacific region is expected to garner considerable growth during the forecast period owing to increasing adoption of advanced healthcare technologies and rise in the number of NCDs.

The latest development in India:

A similar initiative, though, as augmentation of physician intervention in patients with Type 2 diabetes for better treatment outcomes, has recently been reported by the Press Trust of India (PTI) on June 13, 2017.

The abstract of the report, among other points, says that an Indian digital diabetes leader has announced “the results from a pilot designed to evaluate the feasibility and scalability of an artificial intelligence-led lifestyle intervention to improve self-management of people living with type 2 diabetes as a supporting tool to existing care in India…. The pilot results suggest that continuity of care between physician appointments for people with type 2 diabetes can be achieved with positive outcomes in a clinically significant, scalable and affordable way through this program. Participants that completed the pilot on average dropped their average blood sugar levels (HbA1c) by 0.59%. Amongst the participants that completed and dropped their HbA1c, the average observed was even higher at 1.04%. In addition, the participants showed a daily active usage of 78% for the duration of the 16-week program.”

This is indeed a laudable initiative by an Indian digital tech company. More such ventures are expected to be forthcoming, taking rapid strides in India. Keeping pace with these developments, “digiceuticals,” I reckon, will spread its wings faster to play a crucial role in preventing, if not treating and managing several serious NCDs – and in most cases without even swallowing any pill.

Conclusion:

The key concept behind ‘digiceuticals’ or digital therapeutics is to exert a strong influence on individual behavior and lifestyle pattern, which are crucial both in prevention, and in controlling the progression of many NCDs. The desired level of change in behavior and lifestyle of individuals can be achieved through custom-made digital software. These are expected to deliver the same, or even better results in such disease conditions, at a much lesser cost, sans any serious side effects.

The ball has already started rolling with considerable success and a discernible promise in this direction. However, accelerating its speed further, and ultimately flooring the gas pedal, would depend on how all concerned stakeholders’, especially the technology experts, doctors, pharma industry, and other health care providers work in-sync with each other, leveraging the true potential of ‘digiceuticals’.

The rapid pace of progress in this endeavor will be a force multiplier in arresting the fast spreading ‘invisible epidemic’, as it were, of many serious chronic diseases or disorders, in a much better and cost-effective way than ever before.

Dawns A New Era: Regenerative Medicine For Degenerative Disease

Posted on July 17, 2017 by Tapan Ray

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 article titled, “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.

Currently, ischemic heart conditions are usually treated either with blood thinning drugs, or blood vessel relaxants. In more serious stages of this condition, doctors prefer angioplasty or other surgical interventions, such as coronary artery bypass.

In this broad perspective, the relevance of the above discovery in addressing various debilitating or life- threatening ischemic conditions, is profound. Its novelty lies in the ability of the scientists making a 3D-printed patch that can be infused with cells to help grow healthy new blood vessels.

An emerging medical space:

The science of ‘Regenerative Medicine’ is increasingly being considered as an emerging medical space aimed at the treatment of those diseases that are usually classified as degenerative, incurable and irreversible. As it appears today, this science has the potential to unfold a new paradigm in this space, where patients can expect cure for many serious ailments, such as, spinal injuries, heart disease, Parkinson’s, Alzheimer’s disease and even diabetes, besides many others.

One more recent pursuit in this much uncharted frontier was reported in the British news daily – ‘The Telegraph’ on February 21, 2017, revealing the outcome of a path-breaking medical study for freezing the progression of a crippling ailment called Multiple Sclerosis (MS). This research followed a unique Stem Cell (SC) transplantation process, and is regarded as the largest long-term follow-up of SC transplantation treatment study of MS in regenerative medicine.

This study, spearheaded by Imperial College London, established that 46 per cent of patients who underwent the treatment did not suffer a worsening of their condition for five years. The process works by destroying the immune cells responsible for attacking the nervous system. This is indeed a very significant development in the space of medical research.

The treatment, called autologous hematopoietic stem cell transplantation (AHSCT), was given to patients with advanced forms of MS who had failed to respond to other medications. However, the researchers noted that the nature of the treatment, which involves aggressive chemotherapy, carried “significant risks”.

As many would know, MS is caused by the immune system malfunctioning and mistakenly attacking nerve cells in the brain and spinal cord, leading to problems with movement, vision, balance and speech. It’s a lifelong condition and often causes serious disability, with no cure still in sight. The disease is most commonly diagnosed in people in their 20s and 30s, although it can develop at any age.

A potential game changer:

According to California Institute for Regenerative Medicine (CIRM), this procedure has a game changing potential for successful use:

To replace neurons damaged by spinal cord injury, stroke, Alzheimer’s disease, Parkinson’s disease or other neurological problems

To produce insulin that could treat people with diabetes, and heart muscle cells that could repair damage after a heart attack, or

To replace virtually any tissue or organ that is injured or diseased

Research on “Regenerative Medicine’ signals a new hope:

Following are examples of just a few more promising developments, indicating that research in ‘Regenerative Medicine’ is taking rapid strides, signaling a new hope:

- A cure for Type 1 diabetes:

According to an international report on October 9, 2014, for the first time after 23 years of research, Harvard University has been able to manufacture millions of beta cells required for transplantation. It could mean a cure for diabetes, and the end of daily insulin injections for patients living with Type 1 diabetes. Although, just around 10 per cent of all diabetes is Type 1, it is the most common type of childhood diabetes.

The report indicated, the stem cell-derived beta cells are presently undergoing trials in animal models, including non-human primates, where they are still producing insulin after several months.

Another report of April 2014 indicates that for the first time, scientists have successfully replaced the damaged DNA of a type 1 diabetes sufferer with the healthy genetic material of an infant donor. When these cells are injected back into the diabetic patient, it is expected that they will begin to produce insulin on their own.

- Restoring vision in macular degeneration:

Yet another study published in ‘The Lancet’ in October 2014 stated that scientists in the United States have announced that single transplant of stem cells has helped restore the sight of patients suffering from incurable forms of blindness due to Age-related Macular Degeneration (AMD). Currently no effective treatments exist for this eye disorder, which can cause complete blindness due to the loss of light-receiving photoreceptor cells in the retina.

To recreate a type of cell in the retina that supports those photoreceptors, the new treatment uses stem cells derived from embryos that are only a few days old and have the ability to develop into any kind of tissue in the body. However, the transplants have proved controversial because they use stem cells derived from spare human embryos left over from IVF treatment.

- A cure for heart failure:

One more international report of May 01, 2014 states, by injecting human stem cells into the organs of macaque monkeys, scientists have been able to regenerate their damaged hearts by up to 40 per cent in just a few weeks. Thus, it appears now that a cure for heart failure could be just a few years away and would mean that even people who are “bed-bound” with heart failure could be “up and about” again within a few weeks.

As on date, the heart muscle cannot be repaired, making people with severe heart failure necessarily wait for a heart transplant, provided the patients are willing, and can afford so.

Conclusion:

There is a host of diseases, including several chronic ailments, such as diabetes, heart conditions, rheumatoid arthritis, or some types of cancer, which can’t be reversed, however, could be managed with a lifelong treatment. For most of these diseases, ‘Regenerative Medicine’ has the potential to be a game changer by transforming many lives.

Moreover, ‘Regenerative Medicine’ is expected not just to bring down the cost of health care and the disease burden significantly, but would also help increasing the economic productivity of a nation considerably.

Currently, medical research of the highest order in this area, has mostly been conducted by various academia of global repute, along with a few in the industry. It should soon involve, besides patients, several industries, including pharmaceuticals and biotech sectors, in a big way.

Nevertheless, this emerging trend sends a clear signal that to treat various chronic, incurable, irreversible and seriously debilitating degenerative diseases ‘Regenerative Medicine’ is now poised to take a giant leap in the health care space. In that process, it would possibly help healing various ailments in a more meaningful, providing a cure for many chronic diseases that was a badly missing piece in the medical science, so far.

Thus, ‘Regenerative Medicines’ to treat many ‘Degenerative Diseases’ signal a great potential to give an altogether new shape and dimension to the future of global health care. It is also expected to ensure lesser lifelong usage of expensive drugs, setting a new normal to bring back the patients’ lives back to the pre-disease state.

Could Vaccine Prevent Heart Attacks?

Posted on July 10, 2017 by Tapan Ray

Could Vaccine Prevent Even Heart Attacks? The question may sound weird to many, but it really appears so, possibly reducing further need of several expensive medications for lifelong use. A good number of academic institutions, besides some biotechnology companies, are taking rapid strides in the newer areas of vaccine development to protect people from various non-infectious serious ailments, including some fatal disorders, such as heart attacks.

In this article, I shall deliberate on this area.

Picking up the thread:

One of the critically important preventive therapy to save millions of precious lives is – vaccination. Way back in 1796, Edward Anthony Jenner not only discovered the process of vaccination, but also developed the world’s first smallpox vaccine to save mankind from this highly infectious and life-threatening disease. As per published data, prior to this discovery, the mortality rate for smallpox was as high as up to 35 percent.

Very appropriately, Jenner is often referred to as the “Father of Immunology”, whose pioneering work has saved more lives than the work of any other person, in that era. Later, in 1901 Emil Von Behring received the first Nobel Prize (ever) for discovering Diphtheria serum therapy for yet another highly infectious disease, affecting mostly infants and children.

Nevertheless, the pioneering work of Edward Anthony Jenner laid the primary substructure of immunology, which continued to be developed as a robust prophylactic measure against various types of, initially infectious and communicable diseases.

Expanded scope for vaccines:

Gradually, the global focus of vaccine development started expanding from prophylactic vaccination for communicable disease such as smallpox, diphtheria, malaria and pneumonia; to non-infectious disorders, like cancer, diabetes and atherosclerosis that often leads to heart attacks and strokes; including several therapeutic vaccines, especially for cancer. The list continues.

In other words, from inducing long-life immunity against exogenous or foreign antigens in infectious diseases caused by microorganisms, to inducing similar immune reaction against the body’s own molecules, which are responsible for precipitating seriously debilitating or life-threatening pathological changes. These include conditions, such as cardiovascular or metabolic disorders and many other chronic ailments, including various types of the deadly disease – cancer.

Would vaccines prevent even heart attacks?

Let me now get back to where I started from: Would vaccines prevent even heart attacks?

Medical experts often say, until a sudden heart attack occurs, patients with atherosclerosis may show no symptoms for decades. This epitomizes the seriousness of this disorder in human population.

Since long, atherosclerosis used to be considered as ‘a lipid-driven disease caused by the continuous accumulation of cholesterol in the arterial intima.’ However, that concept is changing now based on enough scientific evidences. These clearly indicate that ‘atherosclerosis is predominately a chronic low-grade inflammatory disease of the vessel wall with an interplay of humoral, cellular, and locally produced pro-inflammatory factors.’

Atherosclerosis is a chronic low-grade inflammatory disease:

In the above context, a recent research study has arrested the attention of many medical scientists, including several top cardiologists, across the world. This article, published on June 19, 2017, in the peer-reviewed European Heart Journal reported the development of a vaccine that induces an effective immune response in mice to significantly reduce plasma lipids, systemic and vascular inflammation, and atherosclerosis lesions in the aorta.

Leverages the immune system of the body:

In simple words, this cholesterol-lowering vaccine demonstrates how the immune system of the body can be leveraged to lower blood lipids, signaling a strong potential to make drugs, such as statins, possibly irrelevant.

This is the first intervention study based on a well-established, translational mouse model for hyperlipidemia and atherosclerosis. The research found, as compared with the control group, the vaccine reduced total and LDL cholesterol levels in the mice, as well as reduced signs of fatty build-up in the arteries.

Potentially an effective and economical approach:

The authors believe, the vaccine may represent an effective and economical approach, with higher patient compliance, in the treatment and prevention of similar cardiovascular pathologies. Taking the study to its next stage, they have already enrolled human volunteers to conduct the phase one study, for a detailed scientific assessment on how this vaccine will work for the patients suffering from similar disorders.

Another interesting development:

To give just a flavor of the progress of vaccine development in several areas of serious and life-threatening non-communicable diseases, I am quoting below the following interesting study:

June 1, 2016 issue of ‘The Independent’ reported that scientists of Johannes Gutenberg University in Germany have taken a “very positive step” towards creating a universal vaccine against cancer that makes the body’s immune system attack tumors as if they were a virus. The researchers had taken pieces of cancer’s genetic RNA code, put them into tiny nanoparticles of fat and then injected the mixture into the bloodstreams of three patients in the advanced stages of the disease. The patients’ immune systems responded by producing “killer” T-cells designed to attack cancer.

This vaccine was found to be effective in fighting “aggressively growing” tumors in mice. At the same time, such vaccines are fast and inexpensive to produce, and virtually any tumor antigen (a protein attacked by the immune system) can be encoded by RNA, the report said.

How expensive are the R&D costs for vaccines?

In this context, an important related question may well be raised: How expensive are the R&D costs for vaccines? According to a paper published by the US National Library of Medicine and National Institute of Health (NIH):

“A vaccine candidate entering pre-clinical development in 2011 would be expected to achieve licensure in 2022; all costs are reported in 2022 Canadian dollars (CAD). After applying a 9 percent cost of capital, the capitalized total R&D expenditure amounts to $ 474.88 million CAD.”

Some key issues and challenges:

Scientific breakthroughs in genetics and biotechnological research, supported by state of art tools related to information technology, a wide range of vaccine development initiatives, targeting both in infectious and non-infectious diseases, are making rapid progress. However, as I had said before, there are some key issues and challenges that need to be addressed, simultaneously. A few examples of which are as follows:

Actual cost of vaccines goes much beyond their R&D expenses. This is mainly because of dedicated and highly specialized manufacturing facilities required for their mass-scale production, and then for the distribution of the same, mostly using cold-chains.

Around 60 percent of the production costs of vaccines are fixed in nature (National Health Policy Forum. 25. January 2006:14). Thus, such products will need to have a decent market size to be profitable.

Unlike many other medications for chronic ailments, which need to be taken for a long duration, vaccines are administered for a limited number of times, restricting their business potential.

Full neutralization of this cost before keeping a modest margin, could make such high-end vaccines relatively expensive for patients, without adequate financial incentives from the Government.

In conclusion:

The discovery of the interesting vaccine to prevent both fatal and non-fatal heart attacks followed an interesting path, and took a long time of around one and a half decade to go for the phase I human trial. Putting together the facts from the available scientific literatures, the long and arduous path of this journey may be, I reckon, summed up, as follows:

An article published by the Harvard Stem Cell Institute (HSCI) on June 9, 2014 first reported that it’s plausible to prevent heart attacks with vaccination. Nonetheless, it all started even much before that, when in 2003, a group of researchers in France studying families with very high cholesterol levels and very early heart attacks, discovered a specific cholesterol regulator. Mutations in the related gene seemed to be responsible for very high cholesterol levels, and early heart attacks. Further research on the subject continued thereafter, based on this novel finding.

Thereafter, in 2014, HSCI scientists collaborating with researchers at the University of Pennsylvania developed a “genome editing” approach for permanently reducing cholesterol levels in mice with a single injection, potentially reducing heart attack risk by up to 90 percent, reported this Harvard article. ‘Circulation Research’ – a journal of the American Heart Association, published the study online on June 10, 2014.

Currently, in mid 2017, from the article published in the peer-reviewed ‘European Heart Journal’ we get to know that development of a vaccine that can prevent heart attacks is going for phase I clinical trial, following several well-tested and scientific evidence based promises.

The outcome of the final phases of this study will now be keenly followed by the experts. Others will optimistically wait for the D-day – virtually the dawn of a new paradigm of preventing heart attacks through vaccination, well before it can result into any fatal or crippling consequences.

MDGs Break Ground For SDGs: Is India Poised To Achieve The Health Goals?

Posted on April 3, 2017 by Tapan Ray

The Millennium Development Goals (MDGs) were placed in the pages of history amid several other remarkable global initiatives of the United Nations (UN), as the timeframe for achievement of these targets got over in 2015.

In 2000, the leaders of 189 countries signed this historic millennium declaration at the United Nations Millennium Summit for improving the lives of the world’s poorest people. Eight MDGs, were agreed upon by its members, each one supported by 21 specific, measurable targets and more than 60 indicators with clear deadlines, as a concerted global movement in this direction. The eight goals spanned across the areas of poverty alleviation, providing universal primary education, ensuring gender equality, preventing child mortality, meeting maternal health needs, protecting the environment and entering various global partnerships, with a target achievement date of 2015.

Did the glass remain ‘half-full’ or ‘half-empty’?

At the end of 2015 the UN reportedly called the MDGs ‘the most successful anti-poverty movement in history’. However, it could probably be a matter of looking at this glass either as ‘half-full’ or ‘half-empty’.

An interesting article published in the international daily ‘The Guardian’ on July 06, 2015, highlighted some hits and misses of MDGs from the global perspective.

Globally, several goals of the MDGs have not been made for various reasons. Focusing on health-related areas, I find, though the child mortality rate has reduced by more than half over the past two and a half decades from 90 to 43 deaths per 1,000 live births, its MDG target of an expected decline by two thirds could not be achieved. Similarly, the global maternal mortality ratio despite falling by nearly half, was far short of its aim of a two-thirds reduction. Likewise, despite the reduction of the number of new HIV infections by around 40 percent between 2000 and 2013, its MDG goal of halting and beginning to reverse the spread of HIV/Aids by 2015 has not been met.

The overall status in India:

According to the United Nations in India, in the above focus areas, the country has made some progress in reducing its under-five mortality rate, which declined from 125 per 1,000 live births in 1990 to 49 per 1,000 live births in 2013; maternal mortality rate also declined from 437 per 100,000 live births in 1990-91 to 167 in 2009.

India recorded significant progress in reducing the prevalence of HIV and AIDS across different types of high-risk categories, with adult prevalence reducing from 0.45 percent in 2002 to 0.27 percent in 2011. However, a quarter of global TB cases still occur in India with nearly 2.2 million people are diagnosed with the disease annually, and an estimated 220,000 die as a result.

MDGs and India’s achievements:

Coming now to target versus achievements, the Millennium Development Goals India Country Report 2015 released by the Ministry of Statistics & Program Implementation (MoSPI) in February 2015, states that India had put considerable emphasis on all the MDGs with significant progress. Although the nation could meet targets of some of these well ahead of the 2015 deadline, overall, only six of the 18 targets adopted as part of the eight goals in 2000 have been fully met. However, according to another report brought out by the U.N. Economic and Social Commission for Asia and the Pacific, India has met only four of the eight MDGs.

As per Sample Registration System 2013, though the overall reduction of Under 5 Child Mortality Rate (U5MR) was nearly 60 percent happened during 1990 to 2013, India had missed this target.

Similar were the performances for a reduction in the Infant Mortality Rate (IMR) and the proportion of one year old children immunized against measles and improving the Maternal Morality Ratio (MMR). However, the prevalence of HIV among pregnant women aged 15-24 years showed a declining trend and incidence of Malaria also came down. Thus, it appears that the progress made and the achievements recorded in India against MDG targets are indeed a mixed bag.

The same question, therefore, logically follows for India too: Has the glass become ‘half-full’, or remained half-empty post MDG efforts?

MDGs break ground for ‘Sustainable Development Goals (SDGs)’:

The MDGs comprising of eight goals to eradicate extreme poverty, were indeed a laudable concerted global initiative of the United Nations. It could reportedly bring over a billion people out of extreme poverty. According to ‘United Nations (2015): The Millennium Development Goals Report’, during the period of 1990 to 2015, extreme poverty fell in developing countries from 47 to 14 percent. Similarly, the proportion of undernourished people fell by almost half, with almost similar decline in the child and maternal mortality rate. Nevertheless, communicable diseases, gender/income inequalities and striking disparities between rural and urban areas continued to persist with the world’s poor remaining overwhelmingly concentrated in several areas.

Thus, learning valuable lessons and significantly benefitting from them, MDGs broke ground for the next logical global initiative in this genre. As the time-frame for implementation of MDGs got over in 2015, the global leaders on the same platform of the United Nations followed it through with the newly developed ‘Sustainable Development Goals (SDGs)’ in the same year.

While aiming to make the outcomes of the new drive more sustainable with a focus on the environmental goals, SDGs did not altogether jettison some of the unfinished agenda of MDGs – mainly for continuity. Unlike MDGs, SDGs are targeted primarily to the developing, least developed and poorest countries. Nevertheless, all member countries of the UN require participating, fund and actively contribute in achieving SDGs targets, no matter how developed they are.

While MDGs had only 8 goals, 21 targets and 63 indicators, SDGs are a set of 17 goals and 169 targets that all 193 UN Member States, including India have committed to achieve between 2016 and 2030. Importantly, though MDG targets were adopted in 2002 and got over in 2015, its effective time span for achievement was of 25 years, as the baseline data used were for the year 1990 with some subsequent revisions. Whereas the baseline for SDGs starts from 2015 estimates, which may be revised to actual figures as and when these are made available.

Health goals in SDG:

Health has a central place in SDG 3 to ‘ensure healthy lives and promote well-being for all, of all ages’. Briefly speaking, it commits itself to a global effort to eradicate epidemics of both communicable and non-communicable disease and strengthen health systems’ capacity, ensuring Universal Health Coverage (UHC), along with making medicines and vaccines affordable to all. In addition, SDG 3 clearly focuses on mental health issues with suicide being the second leading cause of death globally between the ages of 19 to 25. It also aims at reducing the numbers of deaths and illnesses caused by air, water, and soil pollution and contamination, significantly.

Towards further enhancing public policy efforts, SDG 3 emphasizes on strengthening the implementation of the WHO Framework Convention on Tobacco Control; supporting the research and development of vaccines and medicines; substantially increasing health financing; the recruitment, development, training, and retention of the health workforce; and strengthen early warning, risk reduction, and management of health risks. Besides, a few targets falling under other different goals are also linked to the health goal of SDG 3, in various ways.

SDG 3 targets:

According to the ‘Resolution adopted by the General Assembly on 25 September 2015’ on ‘Transforming our world: the 2030 Agenda for Sustainable Development’, SDG 3 lays down nine key targets, as follows, though a few of which overlap with the MDGs:

Reduce the global maternal mortality ratio to below 70/100,000.
Reduce neonatal mortality to below 12/1,000 and U5MR to below 25/1,000.
End the epidemics of AIDS, tuberculosis, malaria, and neglected tropical diseases and combat hepatitis, waterborne diseases, and other communicable diseases.
Reduce by one-third premature mortality from non-communicable diseases.
Strengthen the prevention and treatment of substance abuse.
Halve the number of global deaths and injuries from road traffic accidents (by 2020).
Ensure universal access to sexual and reproductive health care services.
Achieve universal health coverage.
Reduce the number of deaths and illnesses from hazardous chemicals and air, water, and soil pollution and contamination.

Is India poised for it now?

This is indeed a critical question. I guess, no one can just yet vouch, with a great degree of certainty, what exactly would India ultimately achieve against the SDG 3 targets. That said, I reckon, India has now all its success ingredients in place. Let me deliberate on just a few broad but very important ones out of all those, as hereunder:

With the announcement of the National Health Policy 2017 (NHP 2017) and commitment to the same by none other than Prime Minister Modi himself, focusing on public health has now been recognized as one of the critical ingredients for the future economic prosperity of India. Hence, there is a fair chance now that the nation’s public health expenditure as a percentage of GDP would be gradually raised from around 1.2 percent to 2.5 percent – expectedly by 2020, bringing health in the core development agenda of both the Central and the State Governments.

The unfinished task of achieving MDGs needs to be completed faster, driven by its ongoing momentum. The national and the respective States-specific goals, along with a clear roadmap to achieve the targets within the specified time-frame, outlining the success indicators for each deliverable, assigning accountability to designated individuals with a periodic review system for the same, needs to be put in place, soon, actively encouraged by the current national development oriented Union Government, if not initiated already.

The process of implementation of the Universal Health Coverage (UHC), as enunciated in the NHP 2017 should be hastened. This is necessary to bring the entire population, without any discrimination whatsoever, as the beneficiary of this movement.

Scaling up the capacity building process at a much faster pace for the entire public health infrastructure and service delivery systems, along with skill development programs need to be placed at the center stage of the public health agenda of India, to bring SDG 3 to fruition.

Strategic involvement of private players and the credible NGOs to achieve SDG 3 targets would help move faster to ultimately experience the sense of a great public health related achievement for all concerned within, and probably outside the country, as well.

In conclusion:

As MDGs break ground for SDGs, India seems to me quite poised to achieving its health goals.

Moving towards this direction will invite a sharp focus on addressing the non-communicable diseases, as well, while accelerating the ongoing efforts on maternal and child health, and nutrition.

It goes without saying that meeting SDG 3 targets will require adequate public investments for health, besides a well-crafted and time-bound public health policy, charting a clear roadmap for the same. The current Union Government now appears to have committed to both, putting its National Health Policy 2017 in place.

Once these goals are attained, it will enable India to clearly ‘Ensure healthy lives and promote well-being for all, at all ages’. In that process, a new India will be created where all essential public health related needs and demands of all, irrespective of their socioeconomic status, will be expeditiously taken care of, delivering with precision high quality of products and services.

Hopefully, the transformed India would then demonstrate to the world, as someone had said before, it’s just not a matter of ‘more money for health, but also more health for money’.

Sharper Focus On Vaccine: A Huge Scope To Reduce Disease Burden In India

Posted on January 9, 2017 by Tapan Ray

Several international research studies have conclusively established that the aggressive application of nationally recommended prevention activities could significantly reduce the burden of disease in several areas. Immunization or vaccination program is one such critical areas.

Several ailments, which used to be so common all over the world, can now be effectively prevented through vaccination. The most common and serious vaccine-preventable diseases are: diphtheria, Haemophilus influenzae serotype b (Hib), hepatitis B and C, measles, meningitis, mumps, pertussis, poliomyelitis, rubella, tetanus, tuberculosis, rotavirus, pneumococcal disease and yellow fever. The list of the World Health Organization (WHO) indicates that vaccines are now available for 25 different diseases.

Thus, vaccination can save millions of lives and morbidity that such diseases still cause to a very large number of global population. Thanks to vaccines, two most scary diseases – small pox (totally) and polio (almost totally), have been eliminated from the world.

No doubt, why vaccination was voted as one of the four most important developments in medicine of the past 150 years, alongside sanitation, antibiotics and anesthesia by readers of the ‘British Medical Journal (BMJ)’ in 2007. It has been decisively proved that vaccines are one of the most successful and cost-effective public health interventions, which help preventing over 3 million deaths every year, throughout the world, topping the list in terms of lives saved.

In tandem, concerted efforts need to be made by both the industry and the Governments to improve affordable access to all these vaccines for a larger section of the population, especially in the developing world.

A crying need still exists:

Nevertheless, there is still a crying need for greater encouragement, more resource deployment and sharper focus towards newer vaccine development for many more dreaded and difficult diseases. One such area is malaria vaccine.

Some areas of new vaccine development:

Following is an example of some newer therapy areas where novel vaccines are now reportedly under development:

Malaria vaccine
Cancer vaccine
AIDS
Alzheimer’s disease

Malaria vaccine:

A July 24, 2015 article of the BBC News states, the ‘European Medicines Agency (EMA)’ gave a positive scientific opinion after assessing the safety and effectiveness of the first anti-malarial vaccine of the world – Mosquirix, developed by the British pharma major GlaxoSmithKline.

The vaccine reportedly targets the ‘P. falciparum’, the most prevalent malaria parasite and the deadlier of the two parasites that transmit the disease. At present, in the absence of any licensed vaccines for malaria, the main preventive measures to contain the spread of this parasitic disease are spraying of insecticides, use of other mosquito repellent and mosquito nets.

However, it was observed during its clinical trial that he best protection with this vaccine was achieved among children aged five to 17 months, receiving three doses of the vaccine a month apart, plus a booster dose at 20 months. In this group, cases of severe malaria were cut by a third over a four-year period, the report said.

Some concern was also expressed, as the effectiveness of the vaccine waned over time, making the booster shot essential, without which the vaccine did not cut the rate of severe malaria over the trial period. Moreover, the vaccine did not prove very effective in protecting young babies from severe malaria.

This caused a dilemma for the ‘World Health Organization (WHO)’. On the one hand, the stark reality of malaria killing around 584,000 people a year worldwide, and on the other, lack of conclusiveness in the overall results for this vaccine. Therefore, the world health body decided at that time to further consider about it, soon after the experts’ deliberation on whether to recommend it for children, among whom trials have yielded mixed results, gets completed.

The good news is, on November 18, 2016, Newsweek reported the announcement of the W.H.O, that Mosquirix will be piloted across sub-Saharan Africa in 2018, after a funding approval of US$ 15 million for this purpose.

Cancer vaccines:

According to the National Cancer Institute, which is a part of the National Institutes of Health (NIH) of the United States, cancer vaccines belong to a class of substances known as biological response modifiers. Biological response modifiers work by stimulating or restoring the immune system’s ability to fight infections and disease. There are two broad types of cancer vaccines:

Preventive (or prophylactic) vaccines, which are intended to prevent cancer from developing in healthy people.

- Persistent infections with high-risk human papillomavirus (HPV) types can cause cervical cancer, anal cancer, oropharyngeal cancer, and vaginal, vulvar, and penile cancers. Three vaccines are approved by the US Food and Drug Administration (FDA) to prevent HPV infection: Gardasil®, Gardasil 9®, and Cervarix®.

- Chronic Hepatitis B virus (HBV) infection can lead to liver cancer. The FDA has approved multiple vaccines that protect against HBV infection, such as, Engerix-B and Recombivax HB, which protect against HBV infection only.

Treatment (or therapeutic) vaccines, which are intended to treat an existing cancer by strengthening the body’s natural immune response against the cancer. Treatment vaccines are a form of immunotherapy.

- In April 2010, the USFDA approved the first cancer treatment vaccine. This vaccine, sipuleucel-T (Provenge®), is approved for use in some men with metastatic prostate cancer. It is designed to stimulate an immune response to prostatic acid phosphatase (PAP), an antigen that is found on most prostate cancer cells.

Another type of cancer vaccine is currently being developed, known as the Universal Cancer Vaccine.

Universal Cancer Vaccine, June 1, 2016 issue of ‘The Independent’ reported that scientists of Johannes Gutenberg University in Germany have taken a “very positive step” towards creating a universal vaccine against cancer that makes the body’s immune system attack tumors as if they were a virus. The researchers had taken pieces of cancer’s genetic RNA code, put them into tiny nanoparticles of fat and then injected the mixture into the bloodstreams of three patients in the advanced stages of the disease. The patients’ immune systems responded by producing “killer” T-cells designed to attack cancer.

The vaccine was found to be effective in fighting “aggressively growing” tumors in mice. At the same time, such vaccines are fast and inexpensive to produce, and virtually any tumor antigen (a protein attacked by the immune system) can be encoded by RNA, the report said.

The analysts forecast the global cancer vaccines market to grow at a CAGR of 27.24 percent over the period 2014-2019.

HIV/AIDS Vaccine:

The 21st International AIDS Conference (AIDS 2016) held in Durban, South Africa from July 18 to 22, 2016, revealed that a vaccine against HIV will be trialed in South Africa later in 2016, after meeting the criteria needed to prove it, could help fight the epidemic in Africa. A small trial, known as HVTN100, took place in South Africa in 2015 to test the safety and strength of immunity the vaccine could provide, ahead of any large-scale testing in affected populations.

This development reportedly has its origin in a large landmark 2009 trial of RV 144 vaccine in Thailand, demonstrating the proof of concept that a preventive vaccine with a risk reduction of 31 percent could effectively work. The trial was supported by the World Health Organization (WHO) and UNAIDS. The clinical trial participants who received Vacc-4x, reportedly “experienced a 70 percent viral load decrease relative to their level before starting Anti-Retroviral Therapy (ART), compared with no notable reduction among placebo recipients.”

Alzheimer’s disease vaccine:

A vaccine for Alzheimer’s disease could be trialed in human within the next 3-5 years, after researchers from the United States and Australia have uncovered a formulation that they say successfully targets brain proteins, which play a role in the development and progression of the disease, states a July 18, 2016 report published in the ‘Medical News Today (MNT)’.

This vaccine generates antibodies that target beta-amyloid and tau proteins in the brain – both of which are considered hallmarks of Alzheimer’s disease. In their study, the researchers found that the formulation was effective and well-tolerated in Alzheimer’s mouse models, with no reports of adverse reactions. The vaccine was also able to target the proteins in brain tissue from patients with Alzheimer’s.

Study co-author Prof. Michael Agadjanyan, Institute for Molecular Medicine, California said: “This study suggests that we can immunize patients at the early stages of AD (Alzheimer’s disease), or even healthy people at risk for AD, using our anti-amyloid-beta vaccine, and, if the disease progresses, then vaccinate with another anti-tau vaccine to increase effectiveness.”

If the vaccine continues to show success in these preclinical trials, the researchers envisage that they could be testing the vaccine in individuals at high risk for Alzheimer’s, or those in the early stages of the disease, within the next 3-5 years.

More details on vaccine development:

A 2012 report on vaccines, published by the Pharmaceutical Research and Manufacturers of America (PhRMA) give details of vaccines under development.

Vaccine requirements of the developing world:

Developing countries of the world are now demanding more of those vaccines, which no longer feature in the immunization schedules of the developed nations. Thus, to supply these vaccines at low cost will be a challenge, especially for the global vaccine manufacturers, unless the low margins get well compensated by high institutional demand.

Issues and challenges:

To produce a safe, effective and marketable vaccine, besides R&D costs, it takes reportedly around 12 to 15 years of painstaking research and development process.

Moreover, one will need to realize that the actual cost of vaccines will always go much beyond their R&D expenses. This is mainly because of dedicated and highly specialized manufacturing facilities required for mass-scale production of vaccines, and then for the distribution of the same mostly using cold-chains.

Around 60 percent of the production costs of vaccines are fixed in nature (National Health Policy Forum. 25. January 2006:14). Thus, such products will need to have a decent market size to be profitable. Unlike many other medications for chronic ailments, which need to be taken for a long duration, vaccines are administered for a limited number of times, restricting their business potential.

Thus, the long lead time required for the ‘mind to market’ process for vaccine development together with high cost involved in their clinical trials/marketing approval process, special bulk/institutional purchase price and limited demand through retail outlets, restrict the research and development initiatives for vaccines, unlike many other pharmaceutical products.

Besides, even the newer vaccines will mostly be required for the diseases of the poor, like Malaria, Tuberculosis, HIV and ‘Non-Communicable Diseases (NCDs)’ in the developing countries, which may not necessarily guarantee a decent return on investments for vaccines, unlike many other newer drugs. Thus, the key issue for developing a right type of newer vaccine will continue to be a matter of pure economics.

India needs a vibrant vaccine business sector:

For a greater focus on all important disease prevention initiatives, there is a need to build a vibrant vaccine business sector in India. To achieve this objective the government should create an enabling ecosystem for the vaccine manufacturers and the academics to work in unison. At the same time, the state funded vaccine R&D centers should be encouraged to concentrate more on the relevant vaccine development projects, ensuring a decent return on their investments for long-term economic sustainability.

Often, these stakeholders find it difficult to deploy sufficient fund to take their vaccine projects successfully through various stages of clinical development to obtain marketing approval from the drug regulator, while earning a decent return on investments. This critical issue needs to be urgently addressed by the Government to make the disease prevention initiatives in the country sustainable.

A possible threat to overcome:

As per reports, most Indian vaccine manufacturers get a major chunk of their sales revenue from exports to UN agencies, charitable organizations like, the Bill & Melinda Gates Foundation, GAVI, and other country-specific immunization programs.

The report predicts, the virtual monopoly that Indian vaccine manufacturers have enjoyed in these areas, will now be challenged by China, as for the first time in 2012, the Chinese national regulatory authority received ‘pre-qualification’ certification of WHO that allows it to approve locally manufactured vaccines to compete for UN tenders.

Conclusion:

Keeping this in perspective, vaccine related pragmatic policy measures need to be taken in the country for effective disease prevention, covering all recommended age groups, of course, with an equal focus on their effective implementation, without delay. Consequently, this will not only help reduce the disease burden in the country, but also provide the much-awaited growth momentum to the vaccine market in India.

Alongside, increasing number of modern imported vaccines coming in, would help India address one of its key healthcare concerns effectively, and in a holistic way.

It is about time to aggressively garner adequate resources to develop more modern vaccines in the country. In tandem, a rejuvenated thrust to effectively promote and implement vaccine awareness campaigns, would help immensely in the nation’s endeavor for disease prevention with vaccines, that offers a huge scope to reduce disease burden, for a healthier India.

Awaiting The Two To Tango: Pharma Innovation And Public Health Interest

Posted on January 2, 2017 by Tapan Ray

“The rewards for the breakthrough drug discovery must be substantial, but if prices are the only mechanism through which returns on research flow, affordability will be compromised,” articulated an article titled, ‘Pharmaceutical Policy Reform – Balancing Affordability with Incentives for Innovation’, published in The New England Journal of Medicine (NEJM) on February 25, 2016.

The article arrived at this conclusion, on the backdrop of the high prices of prescription drugs becoming an issue of paramount concern, not just in the United States, but across the world. This concern is so acute that it found its way into policy proposals from both the prime candidates, in the American Presidential election held on November 8, 2016.

Through last several decades, healthcare sector in general and particularly the pharmaceutical industry, witnessed many innovations that cure and effectively manage ailments to improve the general quality of life. It enormously impacted the lives of many in the developed countries, and a few others which offer high quality Universal Health Care in a comprehensive format, for all.

A trickle-down impact:

Nevertheless, even no more than its just a trickle-down impact, helped increase overall life expectancy of the population in many developing and poor countries, mostly driven by the expanding number of cheaper generic drugs, fueled by more treatment and disease management options.

The paper titled, ‘World Population Prospects – The 2015 Revision’ of the Department of Economic and Social Affairs, Population Division of the United Nations’ reported that the life expectancy at birth rose by 3 years between 2000-2005 and 2010-2015, that is from 67 to 70 years. All major areas shared in the life expectancy gains over this period, but the greatest increases were in Africa, where life expectancy rose by 6 years in the 2000s, after rising by only 2 years in the previous decade.

Similarly, the global life expectancy at birth is projected to rise from 70 years in 2010-2015 to 77 years in 2045- 2050 and to 83 years in 2095-2100. Africa is projected to gain about 19 years of life expectancy by the end of the century, reaching 70 years in 2045-2050 and 78 years in 2095-2100. Such increases are contingent on further reductions in the spread of HIV, and combating successfully other infectious as well as non-communicable diseases.

The availability of cheaper generics gave some respite:

Out of a total population of 7.3 billion, as the above report says, the World Bank estimated that in 2013, 767 million people still lived on less than US$ 1.90 a day. Unfortunately, despite the greater availability of a large variety of cheaper generic drugs, the basic health care remains elusive to hundreds of millions of people in the world.

What causes more concern is the fact that 6 percent of people in low and middle-income countries are tipped into or pushed further into extreme poverty because of health spending, as the June 12, 2015 report of the World Health Organization (W.H.O) and the World Bank highlights. W.H.O has estimated that over a billion population of the world still suffer from neglected tropical diseases.

How many people benefitted from pricey patented drugs?

Nevertheless, despite so much innovation in the pharma industry, access to these new drugs remains elusive to a large section of even some the most developed nations, such as the United States, as they can’t afford these high-priced drugs. The overall situation, in this regard, is going from bad to worse. For example, the March 16, 2015 study published in the Mayo Clinic Proceedings reveals that the average annual cost of cancer drugs increased from roughly US$ 10,000 prior to 2000 to an astounding over US$ 100,000 by 2012.

Further, an August 31, 2015 article published in the ‘Health Affairs’ also gave examples of Biogen Idec’s multiple sclerosis drug, Tecfidera, which costs US$ 54,900 per patient per year; hepatitis C cures from Gilead Sciences, with a sticker price of $84,000 per patient; and Orkambi, a cystic fibrosis drug from Vertex Pharmaceuticals approved this month, priced at a whopping US$ 259,000 per year. A Kaiser Health Tracking Poll last July 2015 found that 73 percent of Americans find the cost of drugs to be unreasonable, and most blamed drug manufacturers for setting prices too high, the article stated.

The health care scenario in India is no better:

A study conducted by the ‘National Sample Survey Organization (NSSO)’ from January to June 2014, which was the 71st round of the ‘National Sample Survey’, and published in the ‘Health in India’ report, narrates a very gloomy picture for India, especially for a clear majority of those who incur ‘out of pocket’ expenses on medicines. The report states, out of all health expenditure, 72 percent in rural and 68 percent in urban areas was for buying medicines for non-hospitalized treatment.

Thus, many patients cannot afford health services, even when these are needed the most. As many as 68 percent of patients in urban India and 57 percent in rural areas attributed “financial constraints” as the main reason to take treatment without any medical advice, the report adds.

In this situation, the challenges that the Governments and the civil society are facing in many developing, and to some extent even in some developed countries, though for different reasons, are multi-factorial. It has been well established that the humongous global health care challenges are mostly of economic origin.

Pharma innovation benefitted the developed countries more:

A study titled, ‘Pharmaceutical innovation and the burden of disease in developing and developed countries’ of Columbia University and National Bureau of Economic Research, to ascertain the relationship across diseases between pharmaceutical innovation and the burden of disease both in the developed and developing countries, reported that pharmaceutical innovation is positively related to the burden of disease in the developed countries but not so in the developing countries.

Making the two to tango:

These facts prompt the need to make the pharma innovation and public health interest to tango. Several suggestions have been made and initiatives taken in this direction. Some of which are as follows:

Responding to this need, in 2006 W.H.O created the ‘Intergovernmental Working Group on Public Health, Innovation and Intellectual Property (IGWG)’. The primary focus of IGWG is on promoting sustainable, needs-driven pharmaceutical R&D for the diseases that disproportionately affect developing countries. One positive effect of this global debate is that some global pharmaceutical companies have initiated their R&D activities for neglected tropical diseases, such as, Malaria and Tuberculosis. Many charitable organizations like, Bill & Melinda Gates Foundation and Clinton Foundation, are allocating significant funds for this purpose.

A paper titled, “Optional reward for new drugs for developing countries” published by the Department of Economics, University of Calgary, Institute of Health Economics, proposed an optional reward fund for pharmaceutical innovation aimed at the developing world to the pharmaceutical companies, which would develop new drugs while ensuring their adequate access to the poor. The paper suggests that innovations with very high market value will use the existing patent system, as usual. However, the medicines with high therapeutic value but low market potential would be encouraged to opt for the optional reward system. It was proposed that the optional reward fund should be created by the governments of the developed countries and charitable institutions to ensure a novel way for access to innovative medicines by the poor.

‘Open Innovation’ or the ‘Open Source Drug Discovery (OSDD)’ is another model of discovering a New Chemical Entity (NCE) or a New Molecular Entity (NME). Imbibing ‘Open Innovation’ for commercial results in pharmaceuticals, just has what has happened to android smartphones, would encourage drug discovery initiatives, especially for the dreaded disease like cancer, to make these drugs affordable for a very large section of people across the globe. In this model, all data generated related to the discovery research will be available in the open for collaborative inputs. In ‘Open Innovation’, the key component is the supportive pathway of its information network, which is driven by three key parameters of open development, open access and open source. This concept was successfully used in the ‘Human Genome Project’ where many scientists, and microbiologists participated from across the world to sequence and understand the human genes. Currently, pharmaceutical R&D is a well-protected in-house initiative of innovator global companies to maximize commercial benefits. For this reason, only a limited number of scientists working for the respective innovator companies will have access to these projects. In India, the Council of Scientific and Industrial Research (CSIR) is the champion of the OSDD movement, locally. CSIR believes that for a developing country like India, OSDD will help the common man to meet his or her unmet medical needs in the areas of mainly neglected tropical diseases.

Conclusion:

Thus, the ongoing heated debate on Innovation, Intellectual Property Rights (IPR) and Public Health Interest is gathering steam all over the globe.

Argumentative Indians are also participating in this raging debate. I reckon rightly so, as India is not only the largest democracy of the world contributing 16.7 percent of the global population, it is also afflicted with 21 percent of the global burden of disease. Considering this, the reason for similar heated debate in our country is indeed no-brainer to anyone.

Many would possibly not disagree, both encouraging innovation and safeguarding the public health interest are equally important to any society, be it in the developed nations or developing countries. Nevertheless, some constituents of ‘Big Pharma’ and their trade association still highlight that ensuring access to high price innovative drugs is the responsibility of the respective Governments. Any other regulatory mechanism to bring down such prices will be construed as a barrier to encouraging, protecting and rewarding innovation.

Be that as it may, most other stakeholders, across the world, especially the patients, are awaiting these two goals to tango. From that point, I reckon, giving a quick shape to commercially well-tested initiatives, such as, ‘Open Innovation’ model could well be an important step to ensure access to innovative new medicines for a larger number of patients of the world, meeting their unmet medical needs with greater care.

Immunization Still Remains A Low-Budget Neglected Area In India

Posted on December 19, 2016 by Tapan Ray

Although India is a leading producer and exporter of vaccines, the country has the greatest number of deaths among children under 5, and the majority are from vaccine-preventable diseases. Less than 44 percent of India’s young children receive the full schedule of immunizations, commented a research study of Michigan University of the United States.

This is noteworthy, as vaccines are one of the most successful and cost-effective public health interventions. The World Health Organization (WHO) defines vaccines as:

“A vaccine is any preparation intended to produce immunity to a disease by stimulating the production of antibodies. Vaccines include, for example, suspensions of killed or attenuated microorganisms, or products or derivatives of microorganisms. The most common method of administering vaccines is by injection, but some are given by mouth or nasal spray.”

Vaccines help prevent over two to three million children each year. However, another 1.5 million children still die from diseases that could be prevented by routine vaccines, as estimated by the WHO.

“The developing world should no longer experience 450,000 preventable deaths each year from rotavirus, nor 145,000 from measles. By the same token, there should no longer be 2000 preventable deaths each year from influenza in Australia. It is time to use our global health efforts to address the most pressing risks, both at home and abroad,” expects another article published in the Volume 45, No.1, January-February 2016 edition of the journal of ‘Australian Family Physician (afp)’

Nevertheless, the bottom line is, an estimated 19.4 million infants worldwide is still missing out on basic vaccines, which otherwise come rather easily to the children of the developed nations of the world, as per the ‘Fact Sheet’ of the World Health Organization (W.H.O) of September 2016.

A commendable global initiative:

To resolve this inequity, in January 2000, the Global Alliance for Vaccines and Immunization (GAVI) was formed. This initiative was mainly aimed at generating sufficient fund to ensure availability of vaccines for children living in the 70 poorest countries of the world.

The GAVI Alliance has been instrumental in improving access to six common infant vaccines, including those for hepatitis B and yellow fever. GAVI is also working to introduce pneumococcal, rotavirus, human papilloma virus, meningococcal, rubella and typhoid vaccines in not too distant future.

Current ground situation in India:

In this area, the prevailing situation in India is much worse.

The Global consulting major – McKinsey in its report titled, “India Pharma 2020: Propelling access and acceptance, realizing true potential” stated that at 2 percent penetration, the vaccines market of India is significantly under-penetrated with an estimated turnover of around US$ 250 million, where the private segment accounts for two-thirds of the total. McKinsey expects the market to grow to US$ 1.7 billion by 2020.

Some of the important reasons for poor penetration of the vaccine market in India can be found in a March 02, 2016 research article published in the ‘Michigan News’ of the University of Michigan. The paper articulated some important facts, as follows:

Out of 26 million children born in India every year, two-thirds of them do not receive their vaccinations on time, prolonging their susceptibility to diseases and contributing to untimely deaths.

Only 18 percent of children are vaccinated with the recommended three doses of DPT vaccine.

Only 12 percent of children are vaccinated with the measles vaccine by the required age of 9 months, although 75 percent are vaccinated by age 5. This delay in vaccination can contribute to frequent outbreaks of measles in India.

India is adding vast numbers of new children who need vaccination, while the older ones remain under or unvaccinated because of immunization delays, is like “walking too slowly on a moving treadmill – you continually fall further back.”

India hopes to add rotavirus to its Universal Immunization Program, a free government-approved vaccination program that was looked at in this study.

The government has the infrastructure to deliver vaccines, but the motivations for delivering all vaccination doses decreases over time.

India hopes to add rotavirus to its Universal Immunization Program, a free government-approved vaccination program that was looked at in this study.

Needs both policy and budgetary support:

As stated above, the overall immunization scenario in India, as on date, is rather grim. Besides, in view of the humongous disease burden of India, immunization program with various types of vaccines should receive active encouragement from the government as disease prevention initiatives, at least, keeping the future generation in mind. In the next Union Budget of India, this issue should attract fresh policy measures, spearheaded by the Central Government, with requisite fund allocation both by the Central and State Governments.

Low immunization budget and other key barriers:

‘Health Affairs’ – a leading peer-reviewed journal on health policy thought and research, highlighted that India spends woefully little on routine immunization. Quoting data published by the Union Ministry of Health the report stated, only 2.1 percent of the national government’s health budget is allocated to routine immunization – a small amount given the country’s large population and the number of births. Although vaccines used in India are primarily provided free and through the government channels, over 30 percent of the population still purchase vaccines from the private market as a part of their out of pocket expenses.

Besides, there is a long list of other challenges to India’s immunization program. These include a shortage of trained personnel to manage the program at both the national and state levels; the need to undertake innovations in vaccines, disease surveillance, vaccine procurement, and effective vaccine management; the absence of good data on disease burden to inform vaccination priorities; the lack of baseline surveillance data for monitoring the effects of vaccination; and the absence of a system of routine reporting and surveillance, the report stated.

Everyone in the country is expected to fulfill the individual responsibility to get their own children properly vaccinated by properly following, and completing the vaccination schedule. Better all-round and ongoing communication of the long-term benefits of vaccination for many serious disease prevention against negligible side effects, could create greater awareness for compliance.

Indian vaccine market and the key local players:

A report titled ‘Vaccines Market in India 2013’, published by Netherlands Office of Science & Technology, New Delhi, estimated that vaccines contributed largest share in the total Biopharma sales with estimated sales of US$ 602 million in FY 2011-12 over US$ 417.5 million of the previous year. Over half of the top 10 firms in the industry are active in the private sector vaccines market has recorded a growth of about 25 percent.

India is not just a leading producer and exporter of vaccines, it develops and markets complex vaccines, such as, pentavalent rotavirus vaccine. There are around 13 major vaccine manufacturers in India. Companies like, Serum Institute, Shantha Biotecnics, Bharat Biotech and Panacea Biotech are taking commendable strides in this direction. Bharat Biotech is incidentally the largest Hepatitis B vaccine producer in the world.

Around 43 percent of the global Universal Immunization Program vaccine supply (more than 70 percent in the case of single vaccine) reportedly comes from India. Indian vaccine major Serum Institute is reportedly one of the largest suppliers of vaccines to over a 130 countries of the world and claim that ’1 out of every 2 children immunized worldwide gets at least one vaccine produced by Serum Institute.’

Expand Government immunization product spectrum:

It is high time for the Union Ministry of Health to expand the product spectrum for vaccines, as an integral part of its disease prevention program. It is recommended that the routine immunization program of India should now include other important vaccines, such as, Haemophilus influenzae type b, hepatitis B, and rotavirus, as recommended by the National Technical Advisory Board (DTAB) on Immunization.

Conclusion:

Against this backdrop, a holistic immunization program can no longer remain a low-budget and virtually neglected area in India.

Effective resolution of this important issue by the Government would require both the Union and the State Governments to increase their respective budget significantly. It would help launching a well-integrated multi-pronged approach to include most of the remaining one third of the population in the state-run immunization program.

In tandem a strategic pathway needs to be crafted to expand the immunization product spectrum, increase awareness to encourage more household to take part in the holistic immunization initiatives for disease prevention, and counter the anti-vaccine advocates effectively. There is also an urgent need to make more investments in disease surveillance. An integrated approach towards all these initiatives would significantly help reduce the overall burden of disease in the country.

‘The Memory Thief’ Still Eludes Grasp Of Pharma R&D

Posted on February 1, 2016 by Tapan Ray

Over several decades, in fact, since its very inception, pharma R&D has been playing a crucial role in alleviating diseases of various types – from severe acute infections, to a large variety of non-infectious chronic illnesses, including many dreaded diseases, such as, cancer.

In the battle against diseases, pharma research and development initiatives, both by a large number of academia and also the pharma players, have mostly won, decisively. R&D has been consistently coming out with flying colors, both in finding cures and also in effective disease management, to prolong and improve the quality of life of billions of people, the world over.

However, there is still an important disease area, where pharma R&D has not been successful yet. Without any prior warning, this disease stealthily affects the human brain and completely erases the entire lifetime memory of the person, gradually but surely, over a relatively short period of time. This disease is known as Alzheimer’s, following the name of Dr. Dr. Alois Alzheimer, who first detected it in 1906. Due to its devastating impact on human memory, some, very appropriately, term the Alzheimer’s disease – ‘The memory thief’.

I discussed this subject in one of my previous articles titled, “It Took 90 Years To Accept The Dreaded Disease Discovered In A Mental Asylum”, published in this Blog on December 01, 2014.

A recent alarm for a future epidemic:

A January 6, 2016 paper titled, “Sounding the alarm on a future epidemic: Alzheimer’s disease”, published by the well reputed public research university in the United States, ‘The University of California, Los Angeles (UCLA), made the following noteworthy observation:

“If the aging trend illustrates the success of public health strategies, it also raises the specter of a major public health crisis – a sharp rise in the number of people living with Alzheimer’s disease.”

Causing havoc in many lives and families:

‘Alzheimer’s Disease Education and Referral (ADEAR) Center’ of the United States, currently ranked Alzheimer’s disease as the sixth leading cause of death in the United States, but recent estimates indicate that the disorder may rank third, just behind heart disease and cancer, as a cause of death for older people.

According to Mayo Clinic, the frightful disease – Alzheimer’s, is progressive in nature. At the onset, the afflicted persons may exhibit just mild confusion and some difficulty in remembering.

Tragically, in around five years or a little after, Alzheimer’s would erase the entire lifetime memory of most of the affected persons, when they may even forget the important people in their lives and undergo dramatic personality changes.

The dreaded disease – Alzheimer’s, still without any effective medication in place, has been causing havocs in many lives and families since long, involving many great international personalities too. It is one of those ailments, where the disease process mostly commences almost a decade before the visible appearance of above clinical symptoms.

Worldwide Projections of Alzheimer’s Disease Prevalence:

The above UCLA report highlights the worldwide projections of Alzheimer’s disease prevalence from 2005 to 2050, which includes both the early and late stage patients.

According to this report, the number of people afflicted by this total memory-erasing disease, would grow from 35.26 million in 2015 to as high as 106.23 million populations in 2050, as follows:

Year	Alzheimer’s disease prevalence (in Millions)
2005	25.73
2010	30.12
2015	35.26
2020	41.27
2025	56.55
2040	77.49
2050	106.23

Similar situation in India:

The situation in India seems to be no different, though we are living today in the midst of the hype of ‘Demographic Dividend’.

According to the March 2012 report of ‘The Population Reference Bureau’ of Washington DC of the United States, India’s population with ages 60 and older, who are more prone to Alzheimer’s disease, is projected to increase dramatically over the next four decades, from 8 percent in 2010 to 19 percent in 2050. By mid-century, this age group is expected to encompass 323 million people, a number greater than the total US population in 2012.

Currently available treatment:

At present, there are no treatments available that can stop or slow down the progression of Alzheimer’s disease in the brain of the affected persons.

As I wrote earlier, very often the onset of this disease starts decades before the visible manifestation of even preliminary symptoms. Thus, there is a critical need for early medical interventions to arrest the disease progression.

Again, quoting Mayo Clinic, current Alzheimer’s disease medications and management strategies may at best temporarily improve symptoms. These symptomatic treatments can sometimes, help Alzheimer’s patients maximize cognitive and other related functions to the extent possible, and thereby maintain independence for a little while longer.

Primary reasons:

Many earlier research had postulated that plaques and tangles are primarily responsible for the permanent damage and destruction of nerve cells.

While the plaques are abnormal clusters of beta-amyloid protein fragments between nerve cells, tangles are twisted fibers made primarily of a protein called “tau” that accumulates in the brain cells, damaging and killing them.

The appearance of these two in the brain structure makes the affected persons suffer from almost irreversible memory loss, altered thinking pattern and associated behavioral changes, which are usually serious in nature.

However, I shall discuss below about a very recent research that is focusing on a different and novel target.

Key hurdles in Alzheimer’s drug development:

Despite all these, almost at a regular interval, we have been getting to know about various new studies on Alzheimer’s disease, mostly from academic and scientific institutions. It clearly vindicates, at least, the global academia and also some pharma players, are working hard to get an effective key to unlock the pathway of Alzheimer’s disease process.

The hurdles in developing a suitable drug for effective treatment of Alzheimer’s disease are many. A paper titled, “Researching Alzheimer’s Medicines: Setbacks and Stepping Stones Summer 2015”, published by the Pharmaceutical Research and Manufacturers of America (PhRMA) – a trade association of leading biopharmaceutical researchers and biotechnology companies of the United States, cited the following three major reasons as examples:

Scientists still do not understand the underlying causes and mechanisms of the disease. It remains unknown whether many of the defining molecular characteristics of the disease are causes, effects, or signs of progression. This scientific knowledge gap makes the identification and selection of viable targets for new medicines difficult.

Current preclinical models of Alzheimer’s disease are limited in the extent to which they can be extrapolated or translated to the human condition. Better models are needed to facilitate preclinical testing of drug candidates and better predict the effects of the drug in humans.

The absence of validated, non-invasive biomarkers to identify disease presence and progression means the diagnosis is delayed until an individual becomes symptomatic. This makes it particularly challenging to evaluate, enroll, retain, and follow up with patients in clinical studies. It also makes it challenging to assess the effects of the drug candidate. Ultimately, this leads to long and very expensive clinical trials.

The PhRMA publication also states that “researchers believe that no single medicine will be able to defeat Alzheimer’s; rather, several medicines will probably be needed to combat the disease. Thus, researchers need not one, but an array of options to prevent or treat Alzheimer’s disease.”

High rate of R&D failure, with flickers of success:

The above PhRMA publication also indicates, between 1998 and 2014, 123 medicines in clinical development have been halted and have not received regulatory approval.

In this rather gloomy R&D scenario, there are also some flickers of success in this pursuit.

In a recent study, the scientists at the University of Southampton announced that their findings added weight to evidence that inflammation in the brain is what drives the disease. A drug, used to block the production of these microglia cells in the brains of mice, had a positive effect. The study, therefore, concluded that blocking the production of new immune cells in the brain could reduce memory problems seen in Alzheimer’s disease. This finding is expected to pave the way for a new line of treatment for Alzheimer’s disease.

Currently, most drugs used for the treatment of dementia targeted amyloid plaques in the brain, which are considered as a key characteristic of people with the Alzheimer’s disease. According to an article published in Forbes on March 20, 2015, several amyloid-clearing drugs have failed to show statistically significant benefits in large clinical trials. Notable among those are Bapineuzumab – developed by Elan Pharmaceuticals, Pfizer and Johnson & Johnson failed in 2009; Solanezumab of Eli Lilly failed in 2012; and so did Gantenerumab of Roche in 2014.

The latest study, as quoted above, published in the journal ‘Brain’, on January 8, 2016 suggests that targeting inflammation in the brain, caused by a build-up of immune cells called microglia, could halt progression of the disease.

Another flicker of hope is, another drug being developed by Biogen Idec for the treatment of Alzheimer’s disease appeared to slow down the inexorable cognitive decline of patients’, though in a small and a preliminary study.

Lack of research funding is a critical impediment:

Be that as it may, many experts believe that not enough is still being done in Alzheimer’s research, especially in the area of funding.

In an article titled, “Alzheimer’s disease: are we close to finding a cure?” published by ‘Medical News Today (MNT)’ on August 20, 2014, quoted the Alzheimer’s Society, as follows:

“Dementia is the biggest health and social care challenge of our generation, but research into the condition has been hugely underfunded. This lack of funding has hampered progress and also restricted the number of scientists and clinicians working in the dementia field.”

As an illustration, MNT mentioned that in the United States Alzheimer’s research received US$504 million in funding from the National Institutes of Health (NIH) in 2014, while cancer received more than US$5 billion. Breast cancer alone received more funding than Alzheimer’s at US$674 million.

Quoting an expert in this field the report highlighted, “Other diseases have demonstrated that sustained investment in research can improve lives, reduce death rates and ultimately produce effective treatments and preventions. We have the tools and the talent to achieve breakthroughs in Alzheimer’s disease, but we need the resources to make this a reality.”

Conclusion:

From the published research reports, it appears that the quest to decipher the complicated Alzheimer’s disease process continues, at least by the academic and scientific institutions, with equal zest.

These scientists remain committed to finding out the ‘magic bullet’, which would be able to effectively address the crippling disease. As a result, the research has also moved from discovery of effective amyloid-clearing drugs to search for new molecules that targets inflammation in the brain, caused by a build-up of immune cells called microglia.

Undeniably, the challenges ahead are still too many.

Nevertheless, enough confidence is also building up to halt the epidemic of Alzheimer’s by overcoming those hurdles, the world over. Experts are hoping that both a cure and also successful preventive measures for the disease, are not too far anymore.

Though some Global Pharma majors invested significantly to discover effective drugs for Alzheimer’s disease, overall research funding in this area is still far from adequate, according to the Alzheimer’s Society.

For various reasons, not many pharma players today seem to believe that it would be financially prudent for them to make significant investments in developing new molecules for the treatment of Alzheimer’s – the disease that robs memory of millions of people, completely, and without any prior warning whatsoever.

‘The Memory Thief’ continues to prowl, undeterred, still eluding otherwise brilliant Pharma R&D, across the world.
