Deadly Climate Change Impact On Human Health: How Prepared Is India?

It’s not uncommon to find many people, including heads of countries, expressing their serious apprehensions in public, about the scary impact of climate change. Just the last year, on November 26, 2018, BBC News captured one of such incidences with the astonishing headline: “Trump on climate change report: I don’t believe it.” The findings of this report have underscored, ‘unchecked global warming would wreak havoc on the US economy.’

Similarly, a few years ago, on September 05, 2014,CNN News 18 quoted Prime Minister Narendra Modi as saying: “Climate has not changed. We have changed. Our habits have changed,’ while answering to a question on climate change. Regardless of the outcome of any split-hair analysis of the rationale behind such statements from the world leaders, such public discourse could trivialize the possible catastrophic impact of climate change on the planet earth.

Be that as it may, that climate change is taking place, carrying all its ill-effects, is real now, without any ambiguity. There is also widespread consensus among the members of the United Nations that ‘the Earth is warming at a rate unprecedented during post hunter-gatherer human existence.’

It is worth noting that way back in 2001, the ‘Third Assessment Report of the Intergovernmental Panel on Climate Change’, further recorded: “There is new and stronger evidence that most of the warming observed over the last 50 years is likely to be attributable to human activities”, most importantly the release of greenhouse gases from fossil fuels.

Several ‘International Agreements’, including the Paris Agreement on Climate Change - all supported by hard scientific data, have called for immediate, quantifiable measures in each country to address the ‘wide-ranging environmental threats, such as ozone depletion and long-range transboundary air pollution.’ Against this backdrop, in this article, I shall focus on the dreadful effect of climate change in the proliferation of a wide-variety of ailments, especially infectious diseases, within a few decades. While doing so, let me first have a quick recap on what is ‘Climate Change’, in a simple language.

Climate Change – a quick recap:

According to the United Nations, ‘Climate Change is the defining issue of our time and we are at a defining moment. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. Without drastic action today, adapting to these impacts in the future will be more difficult and costly.’

It’s important to note, although, the planet Earth’s climate is constantly changing over geological time, the current period of warming is occurring more rapidly than many past events. Scientists are concerned that the natural fluctuation or variance, is being overtaken by a rapid human-induced warming, as they emit more greenhouse gases. As these gases get trapped in the atmosphere, more heat is retained that has serious implications for the stability of the planet’s climate, even impacting human health with grave consequences. The World Health Organization (W.H.O) has also warned that the health of millions could be threatened by increases in malaria, waterborne disease and malnutrition.

Its impact human health:

The direct and indirect impact of climate change on human health is profound. Before I go into the specifics, let me indicate some of the direct ones, as captured by the Center for Health and the Global Environment (CHanGE), University of Washington. This is sans any charts and maps, unlike the usual practice:

  • Increasing temperatures are causing poor air quality that can affect the heart and worsen cardiovascular disease.
  • Increasing exposure to pollen, molds, and air pollution, all of which can worsen allergies and other lung diseases, such as asthma.
  • Changes in the geographic range of disease-carrying insects, such as mosquitoes, ticks, fleas and other similar ones, which can fast spread many tropical ailments, such as dengue fever and malaria to humans.
  • Increasing frequency and severity of extreme weather and climate events can cause, besides many physical illnesses, several kinds of mental illnesses – increasing both morbidity and mortality.
  • Frequent flooding events and sea level rise can contaminate water with harmful pathogens and chemicals, potentially causing food-borne and waterborne illnesses.
  • Changing weather patterns affect the quality and quantity of nutritious foods with increasing incidence of under-nutrition and micronutrient deficiencies.
  • Additional stress placed on hospital and public health systems, could limit people’s ability to obtain adequate health care during extreme weather events and disease outbreaks.

Most specific and the deadly one:

The World Health Organization (W.H.O) publication - ‘Climate change and human health – Risks and Responses,’ clearly flagged that ‘Changes in infectious disease transmission patterns are a likely major consequence of climate change.’

Citing a pertinent analogy to explain the reason, it said: “Humans have known that climatic conditions affect epidemic diseases from long before the role of infectious agents was discovered, late in the nineteenth century. Roman aristocrats retreated to hill resorts each summer to avoid malaria. South Asians learnt early that, in high summer, strongly curried foods were less likely to cause diarrhea.”

Would pharma players convert these problems into opportunities?

Curiously, some pharmaceutical investors are researching to fathom potential business opportunities lying underneath the above problem, especially for vaccines and newer antimicrobials. It’s probably a blessing in disguise not just for the drug companies, but also for the general public, considering the following two issues, prevailing in the current scenario:

  • According to W.H.O, Antimicrobial Resistance (AMR) is an increasingly serious threat to global public health. It threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi, causing the success of even major surgery and cancer chemotherapy seriously compromised.
  • ‘Pharmaceutical companies are backing away from a growing threat that could kill 10 million people a year by 2050’, reported a July 19, 2018 article. This is because, ‘Antibiotics Aren’t Profitable Enough for Big Pharma to Make More,’ wrote another article, published in Bloomberg Businessweek, on May 3, 2019.

Interestingly, a recent report analyzed and evaluated how this can be done, and which companies will be benefitted most in that process. 

“Climate change to fetch a big business opportunity for pharma”:

As reported on July 25, 2019, Morgan Stanley told investors that climate change will cause an increased prevalence and rapid spread of infectious diseases that may be a boon for some drug companies with big vaccine portfolios. It also highlighted, between 383 million and 725 million more people may be exposed to Zika, dengue and other diseases by 2050, depending on the pace and severity of global warming.

The analysts estimated, especially 7 pharma companies will be critical to fighting infectious diseases brought on by climate change. According to the research note of thebank, ‘the USD 500 billion infectious disease market could see demand for an added USD 125 billion in new vaccines, or as much as USD 200 billion assuming premium pricing for more complex new treatments.’

The top possible gainers:

Identifying the top possible gainers, Morgan Stanley apprised, vaccine development being more difficult and expensive, companies that are already in that business will have an upper hand.

Hence, Sanofi and GlaxoSmithKline are expected at the top, given their existing pipelines and manufacturing capacity. Takeda and Merck both have vaccines in the works for dengue fever, one of the diseases that climate change is likely to exacerbate. Janssen and Pfizer are both active in the vaccines market, but would need to establish new research programs to take on tropical diseases. ‘Moderna’ is also in a good position because it has demonstrated a potential pipeline for drugs combating the Zika virus., as Morgan Stanley further elaborated.

Nevertheless, Morgan Stanley isn’t the only bank looking at investment opportunities from climate change, on July 24, 2019, Goldman Sachs also, reportedly, said it was hiring a sustainable-finance group that is looking into issues related to sustainability. Thus, on the positive side, climate change could fetch a big business opportunity for many pharma players, across the world.

600 million people at risk for climate change in India:

On June 24, 2019, a reputed national business news daily of India reported, “600 million people at risk: Climate change may soon turn critical in India.” Against this threat, the current public health care infrastructure in the country, continues to remain fragile, as stated in India’s National Health Profile, 13th Issue.

It also states, the cost of treatment has been on the rise in India and it has led to inequity in access to health care services. Intriguingly, the country spends around 1.02 percent of its GDP towards public health, which has remained static to declining over a long period of time. Although, health insurance is a growing segment, it hasn’t taken off fully. Several measures are needed to improve and expand insurance coverage.

Further, according to the report by the Center for Disease Dynamics, Economics & Policy (CDDEP) in the US, India is facing shortage of 600,000 doctors and 2 million nurses. This report was widely quoted by the Indian media, on April 14, 2019.

These facts give a perspective on what is India’s level of preparedness to address the critical health issues related to climate change, especially the havoc that the dreaded infectious diseases can cause to so many.

Conclusion:

Astute health policy makers, including a large section of the top political echelon of the country are, apparently, aware of various ill effects of climate change. They also seem to be cognizant that these are likely to accelerate the worsening health problems of the population, including infectious diseases, asthma and other respiratory diseases.

Assuming, new and modern drugs will keep coming to help treat these ailments, do we have a functioning and efficient public health infrastructure to grapple with such issues. What about high out of pocket expenditure towards healthcare for a large section of the population, regardless of Ayushman Bharat?

As the (W.H.O) publication - ‘Climate change and human health – Risks and Responses’ recommended, ‘early planning for health is essential to reduce, hopefully avoid, near future and long-term health impacts of global climate change. The optimal solution, however, is in the hands of governments, society and every individual—a commitment to a change in values, to enable a full transition to sustainable development.’

That said, as India is also a signatory to the latest Paris Agreement on Climate Change, can we assume, India will walk the talk to significantly contain its deadly impact on human health? How is India preparing itself to meet this great challenge of Probably it is anybody’s guess, at least, as on date?

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

“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.

Open Source Drug Discovery (OSDD) initiative for the tropical diseases by CSIR and cancer by GlaxoSmithKline deserves a big applaud and support from all concerned.

As the name suggest the ‘Open Source Drug Discovery (OSDD)’ is an open source code model of discovering a New Chemical Entity (NCE) or a New Molecular Entity (NME). In this model all data generated related to the discovery research will be available in the open for collaborative research inputs. The licensing arrangement of OSDD where both invention and copyrights will be involved, are quite different from any ‘Open Source’ license for a software development.

In OSDD, 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.

The Objectives of OSDD:

The key objective of OSDD is to encourage drug discovery initiatives, especially for the neglected diseases of the world to make these drugs affordable to the marginalized people, especially of the developing world.

International initiative:

In June 2008, GlaxoSmithKline (GSK) announced in Philadelphia, “It was donating an important slice of its research on cancer cells to the cancer research community to boost the collaborative battle against this disease.”

With this announcement genomic profiling data for over 300 sets of cancer cell lines was released by GSK to the National Cancer Institute’s bioinformatics grid. It has been reported that around 1000 researchers actively contribute to this grid from across the industry, research institutes, academia and NGOs.

Many believe that the OSDD initiative will gain momentum to encourage many more academic institutions, researchers and even smaller companies to add speed to the drug discovery process and at the same time make the NCEs/NMEs coming through such process much less expensive and affordable to a large section of the society.

On an average it takes about 8 to 10 years to bring an NCE/NME to market with a cost of around U.S$ 1.7 billion.

OSDD in India:

In India, Dr. Samir Brahmachari, the Director General of the Council of Scientific and Industrial Research (CSIR) is the champion of the OSDD movement. CSIR believes that for a developing country like India, OSDD will help the common man to meet his unmet medical needs in the areas of neglected tropical diseases.

OSDD in India is a global platform to address the neglected tropical diseases like, tuberculosis, malaria, leishmaniasis by the best research brains of the world, together.

To fund the OSDD initiative of the CSIR the Government of India has allocated around U.S $40 million and an equivalent amount of funding would be raised from international agencies and philanthropists.

It has been reported that current priority of CSIR in its OSDD program is the tuberculosis disease area.

Why tuberculosis?

The published reports indicate, in every 1.5 minutes one person in India dies of tuberculosis and about 33 percent of the global population is infected primarily with Mycobacterium tuberculosis. The world is still quite far from having an effective vaccine or drug, which can offer long term protection against this dreaded disease.

Partnerships of Industry with belief in Open Source systems and models with CSIR in its OSDD project for tuberculosis, could help finding out a suitable answer to this long standing problem, sooner than later.

Success of OSDD initiative of CSIR:

Late November 2009, I received a communication from the CSIR informing that their OSDD project, since its launch in September 2009, has crossed 2000 registered users. The pace of increase in the number of registered users indeed reflects the confidence this initiative has generated among the interested researchers, the world over.

OSDD community of CSIR has several credits to be proud of including open peer review, open funding review, large number of real time data on open lab notebook.

CSIR has also indicated that the next big leap planned by them is to completely re-annotate the MTb genome for which OSDD has launched ‘Connect to Decode’ 2010 (http://crdd.osdd.net). They initially expected about 150 participants to join, but within a week, they got about 450 participants. That is really the strength of collaboration on OSDD!

Congratulations CSIR and its leader Dr. Samir Brahmachari.
