How Cost-Effective Are New Cancer Drugs?

Posted on by

The main reason why cancer is so serious a disease, is the ability of the malignant cells to spread in the body, both locally by moving into nearby normal tissue, and regionally to nearby lymph nodes, tissues, or organs, affecting even the distant parts of the body. When this happens, doctors term it as metastatic or stage IV (four) cancer.

Although most patients with metastatic tumors would eventually die of cancer, the treatment with various types of anticancer drugs, could help prolong life, in varying degree. No wonder, many new anticancer drugs now obtain regulatory approval based on their effectiveness on metastatic cancer patients. Consequently, it has now become almost a routine to administer newer anticancer drugs to patients with early stage of disease, after they have undergone surgery or radiotherapy.

But, these lifesaving drugs are expensive – very expensive! For example, a newer anticancer treatment is often priced at US$ 100,000 or more per patient, which, obviously, a large majority of the population can’t just afford.

Are these new drugs cost-effective?

To put in simple words, cost effectiveness of a drug is generally ‘expressed in terms of a ratio where the denominator is a gain in health from a measure (years of life, premature births averted, sight-years gained) and the numerator is the cost associated with the health gain.’

From this perspective, a January 2015 research study titled, “Pricing In The Market For Anticancer Drugs”, published by the National Bureau Of Economic Research of the United States observed that anticancer drugs like bevacizumab (US$ 50,000 per treatment episode) and ipilimumab (US$120,000 per episode) have fueled the perception that the launch prices of anticancer drugs are fast increasing over time.

To evaluate the pricing trend of these drugs, the researchers used an original dataset of 58 anticancer drugs, approved between 1995 and 2013, and found that launch-prices, adjusted for inflation and drugs’ survival benefits, increased by 10 percent, or about US$ 8,500, per year. This study was restricted to drugs administered with the primary intent of extending survival time for cancer patients and drugs for which survival benefits have been estimated in trials or modeling studies. The researchers did not consider drugs administered to treat pain or drugs that are administered to alleviate the side effects of cancer treatments.

The paper concluded, as compared to the older ones, newer anticancer treatments, generally, are less cost-effective. Despite this fact, the prices of these drugs are rising faster than their overall effectiveness.

How much do these drugs cost to prolong a year of life for cancer patients?

Another paper, titled “Cancer Drugs Aren’t As Cost-Effective As They Used To Be”, published in the Forbes magazine on September 30, 2015, expressed serious concern on the declining cost-effectiveness of new anticancer drugs. The author termed this trend as unacceptable, and more disturbing when providing just a year of life to cancer patients costs around US$ 350,000 to even US$ 800,000. High prices should reflect large benefits, and we need to demand value out of medical interventions – he recommended.

Do the claims of efficacy also reflect the real-world effectiveness?

Providing an answer to this question, a very recent article titled, “Assessment of Overall Survival, Quality of Life, and Safety Benefits Associated With New Cancer Medicines”, published in the well reputed medical journal ‘JAMA Oncology’ on December 29, 2016, concluded as follows:

“Although innovation in the oncology drug market has contributed to improvements in therapy, the magnitude and dimension of clinical benefits vary widely, and there may be reasons to doubt that claims of efficacy reflect real-world effectiveness exactly.”

As stated above, this conclusion was drawn by the researchers after a detail study on the overall survival, quality of life, and safety benefits of recently licensed cancer medicines, as there was a dearth of evidence on the impact of newly licensed cancer medicines.

The authors analyzed in detail health technology assessment reports of 62 cancer drugs approved in the United States and Europe between 2003 and 2013, and found that these were associated with increased overall survival by an average of 3.43 months between 2003 and 2013. Following is a summary of the detail findings:

  • 43 percent increased overall survival by 3 months or longer
  • 11 percent by less than 3 months
  • 30 percent was not associated with any increase in overall survival, which means almost one third of these drugs lacked evidence to suggest their increased survival rate when compared to alternative treatments
  • Most new cancer drugs, though improved quality of life, were associated with reduced patient safety

The researchers expect this study to support clinical practice, and promote value-based decision-making in the cancer drug treatment, besides assessing their cost-effectiveness.

Some overseas Cancer Institutes protested:

In 2012, doctors at the Memorial Sloan-Kettering Cancer Center reportedly announced through ‘The New York Times’ that their hospital would not be using Zaltrap, a newly patented colorectal cancer drug at that time, from Sanofi. This action of the Sloan-Kettering doctors compelled Sanofi to cut the price of Zaltrap by half.

Unlike India, where prices of even cancer drugs do not seem to be a great issue with the medical profession, just yet, the top cancer specialists of the American Society of Clinical Oncology are reportedly working out a framework for rating and selecting cancer drugs not only for their benefits and side effects, but prices as well.

In a 2015 paper, a group of cancer specialists from Mayo Clinic also articulated, that the oft-repeated arguments of price controls stifle innovation are not good enough to justify unusually high prices of these drugs. Their solution for this problem includes value-based pricing and NICE like body of the United Kingdom.

This Interesting Video from Mayo Clinic justifies the argument.

Was it a tongue-in-cheek action from India?

On March 9, 2012, India did send a signal to global pharma players on its apparent unhappiness of astronomical pricing of patented new cancer drugs in the country. The then Indian Patent Controller General, on that day, issued the first ever Compulsory License (CL) to a domestic drug manufacturer Natco, allowing it to sell a generic equivalent of a kidney cancer treatment drug from Bayer – Nexavar, at a small fraction of the originator’s price.

However, nothing has changed significantly since then on the ground for cancer drugs in the country. Hence, many construe the above action of the Government no more than mere tokenism.

In this context, it won’t be out of place recapitulating an article, published in a global business magazine on December 5, 2013 that quoted Marijn Dekkers, the then CEO of Bayer AG as follows:

“Bayer didn’t develop its cancer drug, Nexavar (sorafenib) for India, but for Western Patients that can afford it.”

Whether, CL is the right approach to resolve allegedly ‘profiteering mindset’ at the cost of human lives, is a different subject of discussion.

VBP concept is gaining ground: 

The concept of ‘Value-Based Pricing (VBP)’, has started gaining ground in the developed markets of the world, prompting the pharmaceutical companies generate requisite ‘health outcome’ data using similar or equivalent products.

Cost of incremental value that a product delivers over the existing ones, is of key significance, and should always be the order of the day. Some independent organizations such as, the National Institute for Health and Clinical Excellence (NICE) in the UK have taken a leading role in this area.

Intriguingly, in India, public health related issues, however pressing these are, still do not seem to arrest much attention of the government to provide significant relief to a large majority of population in the country.

Conclusion:

Warren Buffet – the financial investor of global repute once said, “Price is what you pay. Value is what you get.” Unfortunately, this dictum is not applicable to the consumers of high priced life-saving drugs, such as, for cancer.

Prices of new drugs for the treatment of life-threatening ailments, such as cancer, are increasingly becoming unsustainable, across the world, and more in India. As articulated by the American Society of Clinical Oncology in 2014, this is mainly because their prices are disconnected from the actual therapeutic value of products.

Currently, a sizable number of poor and even middle-income patients, who spend their entire life’s saving for treatment of a disease like cancer, have been virtually priced out of the patented new cancer drugs market.

The plight of such patients is worse in India, and would continue to be so, especially when no trace of Universal Health Care/Coverage (UHC) is currently visible anywhere near the healthcare horizon of the country.

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

Posted on by

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.

India Needs More Integrated, High Quality E-Commerce Initiatives In Healthcare

Posted on by
Reply

In the digital space of India, many startups have been actively engaged in giving shape to a good number interesting and path breaking ideas, especially since the last ten years. One such area is ‘electronic commerce’ or ‘e-commerce’.

In the e-commerce business, particularly the following business model is gaining greater ground and popularity:

Here, an e-commerce company plans to generate large revenue streams on hundreds and thousands of items without producing and warehousing any of these, or carrying any inventory, handling, packaging and shipping. It just collects, aggregates and provides detailed and reliable information on goods and/or services from several competing sources or aggregators, at its website for the consumers.

The firm’s strength primarily lies in its ability to draw visitors to its website, and creating a user-friendly digital platform for easy matching of prices and specifications, payment and delivery, as preferred by the buyers.

Growing e-commerce in India:

Today, e-commerce players in the country are not just a small few in number. The list even includes many of those who have already attained a reasonable size and scale of operation, or at least a critical mass. Among many others, some examples, such as, ‘Flipkart’, ‘Bigbasket’, ‘HomeShop18’, ‘Trukky’ and ‘Ola’ may suffice in this context.

Currently, these companies try to satisfy various needs of the consumers related to, such as, lifestyle, daily households, logistics, and other chores, at any time of the users’ convenience and choice, with requisite speed, variety and reliability.

Healthcare initiatives need to catch up:

Despite the overall encouraging scenario, every day in India a large number of the population, even those who can afford to pay, at least a modest amount, still struggle while going through the unstructured and cumbersome process of access to better and comprehensive health care services. The situation continued to linger, despite the ongoing game-changing digital leaps being taken by many startups in various other fields within the cyberspace of India.

Nevertheless, the good news is, it has now started happening in the healthcare space, as well, though most projects are still in a nascent stage. The not so good news is, many of these world class services, though available, are still not known to many.

The medical treatment process is complicated:

The medical treatment process is just not complicated; it is non-transparent too. There is hardly any scope for doing an easy-to-do personal research by common people to ascertain even a ballpark number on the treatment cost, with requisite details of the various processes, that a patient may need to undergo. 

Thus, in pursuit of quality health care at optimal cost in today’s complex scenario in India, one will require to get engaged in time-intensive and complicated research, first to find out, and then to effectively manage the multiple variables for access to comprehensive and meaningful information to facilitate patients’ decision making on the same. For most people, it’s still a challenge to easily collect all these details on a user-friendly platform of any credible and transparent online website.

The usual treatment process:

The usual process that any patient would need to follow during any serious illness is cumbersome, scattered and non-transparent. This is, of course, a natural outcome of the generally deplorable conditions and, in many cases, even absence of quality public health infrastructure in India, forget for the time being about the Universal Health Care (UHC). 

During such illness, one will first need, at least, a General Practitioner (GP), if required a secondary and a tertiary doctor, alongside well-equipped diagnostic laboratories. Then follows the medical prescriptions, or advice for any invasive procedure, buying the right medicines, as required for the treatment of the disease condition, and thereafter comes the desired relief, hopefully. 

Each of these steps being different silos, there were not many easy options available to most patients, in this tortuous quest for good health, but to go for expensive private health care. Currently, this entire process is over-dependent on word-of-mouth information, and various advice from vested interests.

Never before opportunity:

There seems to be an immense opportunity waiting in the wings for any e-commerce business in India, providing a comprehensive and well-integrated information network for the patients directly, enabling them to take well-informed decisions for reliable, cost-effective and high quality health care services.

This has been facilitated by increasing mobile phone usage in India. According to India Telecom Stat of January 2016, the number of mobile phone users in the country has now crossed one billion. Experts believe that a large section of these subscribers will soon be the users of smartphones.

Rapid growth of internet connectivity with the affordable smartphones, fueled by the world’s cheapest call tariffs, commensurate availability of various attractive packages for data usage, would empower the users avail integrated, comprehensive and high quality e-commerce services in the healthcare sector too, sooner than later.

Would it reduce health care cost?

A transparent system of integrated health care services could bring health care cost significantly.

For example, one can find out from such websites, not just a large number of doctors from any given specialty, including dentistry. Alongside will be available many other important information, such as, their location, availability time and fees charged.

This would help patients comparing the doctors from the same specialty, especially from the quality feedbacks published on the website. This would facilitate patients taking a well informed decision for disease treatment according to their individual needs and affordability. The same process could be followed for selecting diagnostic laboratories, or even to buy medicines.

Such open and transparent websites, after gaining desired confidence and credibility of the users, would also help generate enough competition between healthcare service providers, making the private health care costs more reasonable, as compared to the existing practices.

These e-commerce companies would arrange immediate appointments according to the convenience and needs of the patients, and also help in delivering the prescribed medicines at their door steps. 

Some initiatives around the world:

Many startups are now setting shops in this area, around the world. Just to give a flavor, I would cite a few examples, as follows, among many others:

Name Country Services
Doctoralia http://www.doctoralia.com Spain A global online platform that allows users to search, read ratings, and book appointments with healthcare professionals 
iMediaSante http://www.imediasante.com/ France Provides patients to make medical appointments from a mobile for free. 
DocASAP http://www.docasap.com United States An online platform enabling patients to book appointments with the doctors and dentists of their choice.
Zocdoc https://www.zocdoc.com/ United States Solves patient problems with instant online appointment booking, provides verified reviews and tailored reminders.
Lybrate.com https://www.lybrate.com/ India Provides access to a verified online doctor database of over 90,000 medical experts, including in Ayurveda and Homeopathy, for appointments and to ask any question.
Practo http://www.practo.com/ India An online platform for patients to find and book appointments with doctors. Doctors use Practo Ray software to manage their practice.  

An Indian example:

In this sphere, one of the most encouraging Indian examples would be the Bangalore based Practo Technologies Private Ltd. This startup debuted in 2008, and in a comparative yardstick, has been the country’s most successful business in this area, so far. Its key stated goal has been bringing order to India’s rather chaotic health care system.

Currently, Practo connects 60 million users, 200,000 doctors and 10,000 hospitals. According to a May 27, 2016 report of Bloomberg Technology, Practo website is used to book over 40 million appointments, every year.

This e-commerce company also offers online consultations, and home deliveries of medicine. Its software and mobile applications link people and doctors, as well as hospital systems, so that they can effectively manage the visits and billing, while helping patients find physicians and access their digital medical records.

At present, Practo offers services in 35 cities, and plans to extend that to 100 by the end of this year. The company reportedly is now expanding in Indonesia, the Philippines and Singapore, with a future expansion plan in Latin America, starting with Brazil in March 2016.

How would India shape up?

Although, these are still the early days, according to Grand View Research Inc., based in San Francisco in the United States, the global healthcare information technology market is right on track to reach US$ 104.5 billion by 2020. Increasing demand, especially from the middle income population for enhanced healthcare facilities, and introduction of technologically advanced systems, are expected to boost the growth of this industry.

Increasing rural penetration of e-commerce on integrated health care, would be a major growth booster for this industry in India.

Besides its distant competitor Lybrate, Practo does not have any tough competition in India, at present. However, the scenario may not remain the same, even in the near future. 

Keeping an eye on this fast growing market, two former top executives from India’s e-commerce leader – Flipkart are launching their own health-tech startup creating a new rival for Practo, according to the above Bloomberg report. Thus, it is a much encouraging fast ‘happening’ situation in the interesting digital space of the country. 

Conclusion:

Evolution of Indian e-commerce in health care is an encouraging development to follow. It would offer well-integrated, comprehensive and cost-effective health care services to many patients. Gradually penetration of this digital platform, even in the hinterlands of India, would help minimize quality health care related hassle of many patients, along with a significant reduction of out-of-pocket health expenditure cost.

Interestingly, there is no dearth of doomsayers against such novel initiatives, either. A few of them even say, it doesn’t make sense for the doctors to list themselves in the e-commerce directory for the patients to find them, as the patients desperately need them for any medical treatment, in any case. Others counter argue by saying that acquiring patients online should be a preferable way for doctors to maximize their income, among others, especially by eliminating the referral fees, which many specialists in India require paying for the source of referral.

However, I reckon, a larger number of credible and transparent e-commerce websites for integrated healthcare services, all in one website, would enhance competition, bring more innovation, and in that process delight many patients in India. Never before it was so promising, as the country is making a great progress in the smartphones’ usage, along with Internet access, in the country. The unique facility of free search for medical care services would also help patients immensely in choosing quality, and cost effective medical treatment interventions that would suit their pocket. 

To achieve this goal, the highly competitive digital process of integration and aggregation of requisite pre-verified latest information on different health care service providers and aggregators, in the most innovative and user-friendly way, would play a crucial role. In tandem, delivering the prescribed medicines at the patients’ door steps in strict compliance with the regulatory requirements, would really be a treat to follow in the rapidly evolving digital startup space of India.

The name of the game is ‘Idea’. The idea of offering innovative, well-integrated, comprehensive, user-friendly, and differential value delivery digital platforms for healthcare e-commerce. It shouldn’t just overwhelmingly be what the sellers want to force-feed, but where the majority of patients on their own volition can identify the differential values, and pay for these, willingly.

Clinical Trials: Critical Need To Improve Patient Participation With Informed Consent

Posted on by
Reply

On April 13, 2016, an article in the Wall Street Journal (WSJ) titled, “Clinical Trials Need More Subjects” underscored an important point that the rate at which the clinical researchers are able to recruit and retain patients for ‘Clinical Trials (CT)’, has now hit an all-time low. This is vindicated by studies that indicate less than 10 percent of Americans now participate in clinical trials, and only 3 to 5 percent of patients sign up for trials of new cancer therapies, in the largest CT market of the world.

As a result, about 40 percent of CTs do not recruit enough patients to meet their goals, the article highlights. Consequently, a large number of pharma industry sponsored CTs are now, reportedly, moving away from the United States. India should, therefore, take note of this development and pull up the socks.

If similar situation gets replicated in other countries too, and persists, it would be very unlikely that critical and credible medical and scientific knowledge that can significantly improve the treatment outcomes in many serious disease conditions could be meaningfully gathered and put to practice. Its other serious fallouts too, are also not terribly difficult to imagine.

A key medical research tool: 

In pursuit of the advancement of medical knowledge and patient care, CT of drugs is universally considered to be a key medical research tool, as it is the best way to learn what works best in treating various types of diseases. It goes without saying that drugs for all new types of treatments would need to be discovered first through a long and painstaking process of discovery research. These are then purified, and tested in preclinical studies, before a final decision is taken for commencement of CT on human against preset parameters, as deemed necessary.

While going through this stringent process some drugs are found to be safe and effective on human subjects and some others are not, on the contrary may be harmful.

There lies the crucial importance of CT for all scientific evidence based medicines. According to the Department of Health & Human Services of the United States, Clinical research is done only if doctors don’t know:

  • whether a new approach works well with people and is safe and
  • which treatments or strategies work best for certain illnesses or groups of people 

CT, though a small part in the important and lengthy process of developing newer treatments, significantly helps the health care decision makers to decide on the treatments that work best for any patient.

Broad types: 

Pharmaceutical companies usually sponsor CT for new drugs and treatments, which are carried out by the designated research teams, consisting of doctors and other related professionals in different specialized areas.

There are 4 phases in any CT, which are broadly as follows:     

  • Phase I: Here, for a new treatment, an investigational drug is tested for the first time in small numbers, usually between 20 and 100, on healthy volunteers, to identify the proper dosage ranges for drug administration, while critically monitoring its method of absorption, adverse effects and toxicity profile.
  • Phases II: This phase, just as Phase I studies, also tests the drug on, usually between 100 and 300 patients, suffering from the targeted disease conditions. Safety is the main goal of this phase of CT and is programmed towards adjusting treatment doses, monitoring the common side effects, and whether patient’s disease condition improve as a result of the drug. These studies are usually randomized and double-blinded, where neither the patient nor the researchers would know whether a patient is receiving the investigational drug, or a placebo, or a standard treatment.
  • Phase III: In this phase, the investigational new drug goes through rigorous testing of safety, efficacy, and proper dosage levels in a large group of subjects, which may even exceed several thousand, with a specific illness or disease. The key objective is to enable the doctors to evaluate the safety and effectiveness of the treatment for various groups of patients, such as, men versus women, elderly versus young, besides many others. 
  • Phase IV: Such studies are done after the drug receives the marketing approval from the drug regulator. The basic objective of these trials is usually to monitor whether the treatment offers desired benefits or gives rise to long-term side effects, which were not seen in the phase II and III trials. This phase may involve even several hundreds and thousands of patients.

It is worth noting that CT is essential to obtain marketing approval for any new treatment, as required by the drug regulators in the different countries, and takes around 6 to 8 years.

The role of patients:

Patients play a critical role in the entire scientific value chain of any drug evaluation process, especially on human. It is absolutely necessary, particularly in the regulated markets of the world, that all medicines are fully vetted through highly regulated, stringently monitored and well-scrutinized CTs, to ensure safety and effectiveness of each new drug and treatment for the patients.

No CT can take place sans the willingness and informed consent for participation of thousands of patients for any such studies held across the world. Without adequate patient participation in a CT, the drug performance data may also not be credible and thus acceptable to the drug regulator. This would, consequently, make it impossible to bring any new drug for prevention or treatment of various, often life threatening, disease conditions. 

Major reasons for not enough patient participation:

There are many reasons for not enough patients volunteering to participate in the CT, even in India. Some of the major reasons have been identified as follows:

  • Patients often are not aware that such trials also offer a treatment option. In many cases, their doctors too may not be explaining it effectively to them, as a part of their professional discourse. Several studies conclude that trust in a physician is a main reason patients decide to participate in CT.
  • Some patients, after reading media reports, interacting with some NGOs and also from word of mouth, mistrust the CT process and suffer from fear of being a guinea pig.
  • At times, complicated protocols, and eligibility requirements may also be discouraging.
  • Many patients, especially in India, are not very clear about the exact insurance (financial) cover the study provides for them, along with other payments for the care that they would receive during the trial, or for any drug-related long term untoward incident even after completion of the CT.

All these need to be effectively addressed. 

India attractiveness for CT:

The number of CT conducted in India had increased with a rapid pace till 2012, driven by cost arbitrage, treatment-naïve patient population, qualified English speaking medical research professionals that the country offers. According to available reports, in 2009, outside the United States, India was the second most preferred country to conduct CT. Incidentally, at that time, the CT guidelines in India were too loose, quite discretionary, patient-unfriendly and with many gaping holes. This scenario has changed dramatically since 2013, with consequent adverse impact on the number of CT in India.

A 2009 study conducted by Ernst & Young and the Federation of Indian Chambers of Commerce and Industry of India (FICCI), states that India participates in over 7 percent of all global phase III and 3.2 percent of all global phase II trials. The major reasons of India attraction of the global players to conduct CT in the country, were highlighted as follows:

  • Cost of Clinical Trial (CL) is significantly less in India than most other countries of the world
  • Huge treatment-naïve patient pool with different disease pattern and demographic profile
  • Easy to enroll volunteers, as it is not very difficult to persuade poor and less educated people as ‘willing’ participants. This may not be so easy now with the recent amendment of CT guidelines. 

However, there is an urgent need for a world class capacity building in this area to reap a rich harvest.

Improving CT regulations in India:

Not so long ago, it came to light with the help of ‘Right To Information (RTI)’ query that more than 2,000 people in India died as a result of Serious Adverse Events (SAEs) caused during drug trials from 2008-2011 and only 22 of such cases, which is just around 1 percent, received any compensation. That too was a meager average sum of around US$ 4,800 per family.

It has been widely reported that pharmaceutical companies often blame deaths, that occur during trials, on a person’s pre-existing medical condition, and not related to CT.

This gloomy situation is now gradually improving. According to an August 2015 research article titled “Impact of new regulations on clinical trials in India”, published in International Journal of Clinical Trials, 2015 Aug; 2 (3): 56-58, there was a need of strict vigilance and regulations for conducting CT in India, which was much easier than in North America or Europe. In India, the trial participants were exploited because of illiteracy, poverty and lack of awareness of their basic rights in this area. The Central Drugs Standard Control Organization (CDSCO) has now taken a noteworthy step by launching online Clinical Trial Registry-India (CTRI) ensuring accountability, transparency and information sharing on clinical trials in the public domain.

Followed by a tough intervention of the Supreme Court in 2013, Indian Government brought in amendments to the CT guidelines of Schedule Y, in December 2014 which came into force effective June 2015. These long-overdue amendments are expected to strengthen the CT process in India and effectively protect the rights, desired safety and general well-being of the participating subjects, while generating authentic clinical data for new drugs or treatment.

Informed consent:

Obtaining informed consent of the participating patients, is absolutely necessary for the researchers. This has recently been made stringent in India effective June 07, 2013. From that date, to make the sCT process transparent and ensure requisite confidentiality, an audio-visual recording of the ‘informed consent’ process has been made mandatory in the country.

A valid consent would mean that the participants have well understood the risks and benefits of the treatment during the CT period and after, along with the general procedures that he or she would need to undergo during the given time-frame.

However, the question that is still being debated, primarily because of the continuing challenge in defining in each case, beyond any scope of doubt, what should be universally considered as an adequate level of information given to the patients to obtain consent of participation in the CT. 

Financial compensation process:

Currently, the calculation of financial compensation, wherever applicable, is based on a well-defined formula. This system has been made mandatory for the sponsor in India for any trial related injuries or death. Such compensation has to be paid, even when the trial related injury is discerned after the completion of the CT. The concerned participants would receive this compensation over and above the free medical management of injury, which in any case has to be provided by the sponsor.

Hence patient safety and compensation related issues pertaining to CT in India have, to a great extent, been addressed, though there is still more scope for improvement on an ongoing basis.

Another major issue still to be addressed:

It is generally expected that when CT of a new drug is conducted by the global pharma players in India with the participation of Indian patients, the same drug when launched in other countries would also be made available in India for the benefit of Indian patients. 

Unfortunately, the situation is not so, as indicated by a paper titled, “A critical appraisal of clinical trials conducted and subsequent drug approvals in India and South Africa”, published in the BMJ Open on August 31, 2015.

The objective of this study was to assess the relation between the number of clinical trials conducted and respective new drug approvals in India and South Africa.

The study found that out of CTs with the participation of test centers in India and/or South Africa, 39.6 percent (India) and 60.1 percent (South Africa) CTs led to market authorization in the EU/USA, without a New Drug Application (NDA) approval in India or South Africa. 

The paper concluded, despite an increase in CT activities, there is a clear gap between the number of trials conducted and market availability of these new drugs in India and South Africa. Hence, the drug regulatory authorities, investigators, institutional review boards and patient groups should direct their efforts to ensuring availability of new drugs in the market that have been tested and researched on their population, the article suggested. 

I hope, the CDSCO would take remedial measures to address this situation, soon.

Indian pharma players should get their act together:

In view of the international media reports on alleged ‘CT data fudging’ by some of the larger Indian players in the pharma and relator sectors, there is an urgent need of the Indian pharma players to get their acts together, without any further delay.

On April 15, 2016, Reuters reported, “India’s Alkem Laboratories has been accused by Germany’s health regulator of fudging data on clinical trials of an antibiotic and brain disorder drug, becoming the third Indian firm to be scrutinized since 2014 for suspected manipulation of trial data.” However, a day later Alkem said that it was submitting suitable clarifications to the European Medical Agency (EMA).

Be that as it may, if the allegation for such gross violations of basic ethical standards is true, it would bring shame not just to the companies concerned, but also to India as a trusted source for pharma products and services. Such alleged foul play has the potential to ultimately shatter the stakeholders’ confidence, including patients, on CTs done by the Indian players, both for the local and global markets. 

Conclusion:

At the long last, after a grueling experience and tough intervention of the Supreme Court of India, CTs conducted in India are now reasonably well regulated and generally seem to comply with ethical requirements and standards. The question of human ‘guinea pigs’ and its associated concerns have also been adequately addressed by the CDSCO now.

Gradually improving the CT regulatory environment in India, barring some avoidable aberrations, offers some significant direct and indirect benefits to all concerned. Indian pharma is, therefore, expected to handle this sensitive opportunity with great care and following the highest ethical standards. 

This, in turn, would help bring to the market robust evidence-based new drugs and treatment for many types of diseases, and at the same time could facilitate their early access to many patients, at a time of dire need.

Through increasing access to CT, the participating patients would be able to avail several important benefits, such as, new and still unavailable treatment options, especially for those serious ailments, where other existing drugs either are not working effectively with satisfactory results, not affordable to many, or not working at all. In that sense, CT could offer to a sizeable number patients several other treatment options to choose from, especially, for many life-threatening diseases. This important benefit needs to be explained to the patients from credible sources, and thus merits serious consideration by the practicing medical professionals.

However, it is also a fact, particularly, in India that some people are lured to, or voluntarily enroll themselves for CT with an objective to make some extra money. Let me hasten to add that there are many other patients for whom the compensation for participation in the CT is no more than just an extra bonus.

Hence, improved patient participation with informed consent, to avail an important medical option in the disease treatment process, encouraged by the doctors without having any vested interest, has a great potential to create a win-win situation, for all concerned.

The ‘Moonshot’: Access To World-Class Cancer Care, For All

Posted on by

As in every year, February the 4th was celebrated as the ‘World Cancer Day’, across the world, in 2016, as well. Its main objective is to commemorate all the efforts done by the World Health Organization (WHO), the United Nations (UN), including the governmental and nongovernmental health organizations towards formulating a grand strategy to fight against cancer. The strategy is expected to span across cancer prevention, detection and treatment, for all. The key goal of this commendable initiative is to reduce illness and death caused by cancer by 2020, the world over.

The event also encourages to explore various ways to align individuals and groups to do their bit in reducing both the local and the global burden of disease related to cancer.

The last Thursday, the ‘World Cancer Day’ was celebrated in India too, albeit in a low key, as I could fathom, despite its alarmingly ascending trend in the country.

In this context, I would start with my first and a very small example of a sharply contrasting mindset to address the vexing issue of cancer between the largest democracy of the world – India, and the oldest democracy of the globe – America.

The United States (US) this year, like the previous five years on a trot, made this event visible for a large section of people to encourage them to think and act against cancer, in several different ways that they can. The imposing landmark in New York – the magnificent ‘Empire State Building’ was lit in blue and orange, the colors of the ‘Union for International Cancer Control (UICC’), the organizers of this annual event.

A brief recap:

Cancer is now one of the leading causes of death, not just in India, but across the world. Its rate is expected only to go up further in the years ahead, and that too at a brisk pace. Just as the disease is fast spreading across the socioeconomic spectrum, all over, so are the tough access barriers for effective cancer diagnosis, treatment and care, for all, increasing by manifold.

Urgent action is called for in most of the countries of the world by the respective Governments to save precious lives, by effectively overcoming most of these hurdles, soon.

With this backdrop, in this article, I shall explore what is happening on the ground in this direction, at present, drawing examples from the two greatest democracies of the world.

The largest democracy of the world:

Delivering affordable and equitable care for cancer to all, is one of greatest public health challenges of the largest democracy of the world – India. The country is required to face this challenge boldly and squarely, to mitigate the devastating socioeconomic and human costs that this disease is already costing our nation.

This point was reiterated by one of the lead authors of an article published by ‘The Lancet Oncology’ on April 11, 2014. The paper discussed the epidemiology and social context of the growing burden of cancer in India.

According to this paper, around 600,000 – 700,000 deaths in India were caused by cancer in 2012, with more than 1 million new cases of this life threatening disease being diagnosed every year.

Further, the World Health Organization (WHO) also reported that every year, around 145,000 women are diagnosed with breast cancer in India. Unfortunately, around half of them had succumbed to the disease, in 2008.

However, all these numbers should be taken into consideration carefully factoring in very low rates of early-stage detection and poor treatment outcomes in the country.

In this prevailing scenario, cancer is fast becoming a major public health concern in India, with the number of new cancer cases projected to nearly double within the next 20 years.

The average cost of cancer treatment in India:

According to the above ‘Lancet Oncology’ report, in India, the average cost of treating a typical patient with cancer at a government facility would come around US$593. Whereas, the average annual income per person is only U$ 1,219, with 27.5 percent of the population living on or below a daily income level of US$ 0.4.

Besides, most district hospitals, including the regional cancer centers do not have the requisite facilities required to provide quality cancer care to all those patients who need them.

Quoting experts, a newspaper report on June 19, 2014 also stated, around 50 per cent of the diagnosed cancer patients, who also commence their treatments, stop visiting hospitals after two or three cycles of chemotherapy, as they find the cost of treatment is not affordable to them. They also drop out from regular follow-up visits, say the doctors.

Low Government funding for healthcare:

As a result of abysmally poor public funding for healthcare in India, both by the Central and most of the State Governments, the cost of diagnosis and treatment of cancer is increasingly becoming out of pocket, and being catastrophically expensive, going beyond the reach of a large number of patients suffering from this serious ailment.

The socioeconomic impact:

This pathetic public healthcare system in India adversely affects not only the debt ridden poor and middle-class cancer patients, but also the welfare and education of several generations of their respective families.

Thus, cancer has a profound, both social and economic, consequences for the general population in India. This very often leads to family impoverishment and societal inequity, as the study points out.

The oldest democracy of the world:

The oldest democracy of the world – America, is one of the richest countries in the globe, having perhaps the best healthcare facilities and systems. All the latest drugs and diagnostics are also available there. Despite all these, there is a growing inequity in the cancer treatment in America too, with access to quality diagnosis and treatment for cancer patients becoming a major health, economic and political issue for the country.

‘Mayo Clinic Proceedings’ of August 2015, also expressed concern on the high prices of cancer drugs, which are affecting the care of cancer patients and eventually the American health care system.

The report does ring an alarm bell for high cancer care cost for many patients in America. The ‘Proceedings’ highlighted the following reasons, most of which are, quite interestingly, very similar to India: 

  • Cancer will affect 1 in 3 individuals over their lifetime.
  • Recent trends in insurance coverage put a heavy financial burden on patients, with their out-of-pocket share increasing to 20 percent to 30 percent of the total cost.
  • In 2014, all new US Food and Drug Administration (US FDA) approved cancer drugs were priced above US$ 120,000 per year of use. 
  • The average annual household gross income in the United States is about US$ 52,000.
  • For a patient with cancer who needs one cancer drug that costs US$120,000 per year, the out-of-pocket expenses could be as high as US$25,000 to US$ 30,000 – more than half the average household income and possibly more than the median take-home pay for a year.
  • Thus, cancer patients have to make difficult choices between spending their incomes and liquidating assets on potentially lifesaving therapies or foregoing treatment to provide for family necessities, such as, food, housing and education.
  • This decision is even more critical for senior citizens who are more frequently affected by cancers and have lower incomes and limited assets.
  • Because of costs, about 10 to 20 percent of patients with cancer do not take the prescribed treatment or compromise it. It is documented that the greater the out-of-pocket cost for oral cancer therapies, the lower the compliance. This is a structural disincentive for compliance with some of the most effective and transformative drugs in the history of cancer treatment. 
  • Given the rising incidence of cancer in the aging American population, high cancer drug prices will affect millions of Americans and their immediate families, often repeatedly. 

General public wants the US Government to act:

‘The Mayo Clinic Proceedings’ findings were vindicated by the October 2015 Kaiser Health Tracking poll, which reported, 76 percent of the public believes that a top priority for the American president and Congress should be making high-cost drugs for chronic conditions affordable. Yet another Kaiser poll found 72 percent of Americans believe drug costs are unreasonable and 74 percent think that pharma companies, in general, care more about profits than people.

General public expectations and belief do not seem to be any different in India too. 

I reckon, due to similar reasons in most countries of the world, an urgent action is required from the respective Governments to make cancer diagnosis and treatment affordable to all, sooner than later.

Different responses to the same problem:

Let me reiterate here again, that I am comparing India with America on this issue, not for any other reason, but just to give an example and a feel of how much the promised political intent, made for the benefit of the general population of the country, gets translated into reality in the world’s oldest democracy, as compared to the world’s largest democracy.

In India, despite high sound bytes emanating from various leaders of the principal party in power today, the fragile public healthcare system is still gasping for breath, starved by grossly inadequate resource allocations. This gets reflected on the details of national and state budgetary allocations for healthcare in India.

The delay in finalizing and then putting in place for implementation of the “National Health Policy”, which proposed making health a fundamental right and denial of health an offense, also seems to be of low priority for the national Government, at present. If so, this will indeed be quite contrary to its earlier firm promises on improving healthcare in India.

In the United States, as well, similar promises were made by senior politicians during the last national election campaign. The Presidential candidate for the party, which is now in power, created as much hype with matching sound bytes for healthcare reform in America, while seeking votes.

However, the sharp difference between the two similar situations is, having come to power on November 4, 2008 President Barack Obama, fulfilled his promise with a path breaking healthcare reform in his country. On March 23, 2010 he signed into law the ‘Affordable care Act’. It’s a different matter though, like most political decisions, this one also faced its own share of criticism from the American opposition.

The ‘Moonshot’:

Zeroing in specifically to address the agony of cancer patients in America, President Obama has recently initiated a ‘National Mission’ in this area. He has asked his Vice-President Joe Biden to spearhead this mission and get it done expeditiously. Biden enthusiastically accepted to lead this noble ‘National mission’ for mankind and termed it ‘A Moonshot for Cancer Cure’. The White House also announced a resource commitment of US$1 billion on this effort over the next two years.

In his ‘White House’ Blog Post of January 13, 2016 the Vice-President wrote about this project, very close to the ‘World Cancer Day’, which is basically symbolic, just as the ‘International Day of Yoga’, but this specific American ‘National mission’ against cancer does not appear to be so, by any stretch of imagination.

The key objective of this mission is indeed profound. With is effective implementation, the American Government wants to ensure that ‘the same care provided to patients at the world’s best cancer centers, is available to everyone who needs it.’

Joe Biden admitted, though several cutting-edge areas of research and care, including cancer immunotherapy, genomics, combination therapies and innovations in data and technology are revolutionary, all these are currently trapped in silos, preventing faster progress and greater reach to patients. 

It’s not just about developing game-changing treatments. It’s about delivering them to those who need them the most. The community oncologists, who treat more than 75 percent of cancer patients, have more limited access to cutting-edge research and advances, even in America, Vice-President Biden elaborated. 

Two key focus areas:

  • Increase resources, both private and public, to fight cancer.
  • Break down silos and bring all the cancer fighters to work together, share information, and end cancer, as we know it.

The goal of this initiative is to double the rate of progress by making a decade worth of advances in five years. He also outlined the details that he would follow to get this mission implemented on the ground within the set time frame.

“If there’s one word that defines who we are as Americans…” – Biden

Joe Biden concluded this announcement with his natural statesmanship, sans any drama, by saying: “If there’s one word that defines who we are as Americans, it’s ‘possibility.’ And these are the moments when we show up.”

The good news is, the project ‘Moonshot’, as the American Vice-President calls it, has already started with the full commitment of the American Government and backed to the hilt by none other than President Obama himself. The American President has already demonstrated to the world, from the very commencement of his Presidency, that he is a project implementer per excellence, as head of the Government.

Some key barriers to effective 'cancer care' in India:

Coming back to the Indian context, experts do indicate that one of the main barriers to cancer care, in the largest democracy of the world – India, is primarily lack of enough public facilities for early detection of cancer. Thus, even when it is detected considerable disease progression usually takes place. Moreover, most patients lack access to expensive cancer treatment and are compelled to give up the treatment for this reason. Consequently, as the data reveals, less than 30 percent of patients suffering from cancer in India survive for more than five years after diagnosis, while over two-thirds of cancer related deaths occur among people aged 30 to 69.

According to the data of the Union Ministry of Health, 40 percent of over 300 cancer centers in India do not have adequate facilities for advanced cancer care. It is estimated that the country would need at least 600 additional cancer care centers by 2020 to meet this crying need.

Conclusion:

It appears to me, even meeting this basic need for cancer care will be extremely challenging with frugal public healthcare spending in India. As I said before, it gets well reflected in the successive annual budgetary allocations for the same, both by the Central and most of the State Governments. Added to this, the ‘National Health Policy’, which was first drafted and released in December 2014 by the Ministry of Health for the stakeholders’ comments, is yet to be put in place. The draft policy recommended, among many others, making health a fundamental right of Indian citizens.

According to ‘The World Bank’ report, the public expenditure for health as a percentage of GDP of the oldest democracy of the world is already hovering over 8, against around just 1 of the largest democracy of the world. On top of this, the present American Government has committed, even more resources to usher in a new era of hope for all cancer patients with its latest ‘National Mission’ – ‘A Moonshot for Cancer Cure’.

There is a lot to feel good about it, even as an Indian, as this health mission, termed as ‘‘A Moonshot for Cancer Cure’ by the American Vice-President assures that ‘the same care provided to patients at the world’s best cancer centers, is available to everyone who needs it.’ Its overall benefits could possibly reach even the Indian patients…who knows?

Like 2016, and the previous years, the ‘World Cancer Day’ would come and go with the turn of every calendar year. Hopefully, things will be quite different sometime in future. India would possibly initiate the much awaited health care reform in the country and more specifically effective ‘cancer care’ for all, with requisite budgetary provisions in place. Till then, do the cancer patients in India have any other choice, but to eagerly wait for it, hoping for the best outcome?

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

Posted on by
Reply

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.

With Highest Billionaire Wealth Concentration, India Tops Malnutrition Chart in South Asia: “What Future Do You Want?”

Posted on by
Reply

Two recent global research reports, though on different spheres, place India at the top of the respective blocks. However, the take away messages that the studies offer are indeed poles apart in qualitative terms and worth pondering over collectively.

On January 20, 2014, just before the World Economic Forum (WEF) at Davos in Switzerland, Oxfam International released a report warning that by 2016, the world’s wealthiest 1 percent will control almost half of the global assets. Since 2009, the world’s billionaires have seen their share of the asset pie grow from 44 percent to 48 percent.

Before that, a World Bank Report of October 2014 titled, “Addressing Inequality in South Asia”, highlighted that India has the highest billionaire wealth concentration in South Asia.

Billionaire wealth to gross domestic product ratio in India was 12 percent in 2012. This was was higher than other economies with similar development level, namely, Vietnam with its ratio at less than two percent, and China with less than five percent.

This report also clarifies that inequality in South Asia appears to be moderate when looking at standard indicators such as the Gini index, which are based on consumption expenditures per capita. But other pieces of evidence reveal enormous gaps, from extravagant wealth at one end to lack of access to the most basic services at the other.

Stark realities: 

Wealth creation by no means is bad and in fact, is essential for economic growth of any nation, if read in isolation. This is mainly because, as the Oxfam report says, some economic inequality is essential to drive growth and progress, rewarding those with talent, hard earned skills, and the ambition to innovate and take entrepreneurial risks.

Unfortunately, at the same time, as the same World Bank report highlights, the stunted growth of children under fiver years of age, due to malnutrition, has been 60 percent of the total number of children born in the poorest households of India, as compared to 50 per cent in Bangladesh and Nepal.

Moreover, According to UNICEF, every year 1 million children again below the age of five years die due to malnutrition related causes in India. This number is worrisome as it is far higher than the emergency threshold, according to W.H.O classification of the severity of malnutrition.

Highlighting stark inequality in India, the report says, “The net worth of a household that is among the top 10 per cent can support its consumption for more than 23 years, while the net worth of a household in the bottom 10 per cent can support its consumption for less than three months.”

Some poor moved above the poverty line, though grossly inadequate:

According to the same report, from 2004-05 to 2009-10 when India’s GDP registered the highest ever average growth, about 40 percent of poor households moved above the poverty line and around 11 percent of poor population even moved into the middle class. Unfortunately, during the same period around 14 percent of the non-poor population also slipped below the poverty line.

Thus, what needs to be addressed soonest is the issue of vast difference in income between the richest and the poorest leading to an equally huge difference in the access to basic human developmental needs such as, education, healthcare and nutrition.

Adverse impact on expected ‘demographic dividend’ of India:

As legendary Bill Gates said in a recent media interview, “India has got far more kids that are malnourished and whose brains are not developed, way more than any other country. That’s really the crisis.”

If this trend of inequality continues, the ‘demographic dividend’ of India that the country has factored in so intimately in its future GDP growth narrative, could well be no more than a myth.

As US Supreme Court Justice Louis Brandeis once famously said, “We may have democracy, or we may have wealth concentrated in the hands of the few, but we cannot have both.”

The Oxfam report also emphasizes, the extreme levels of wealth concentration occurring today threaten to exclude hundreds of millions of people from realizing the benefits of their talents and hard work.

Social inequality and healthcare challenges:

Health of an individual is as much an integral contituent of the socio-economic factors as it is influenced by a person’s life style and genomic configurations. Important research studies indicate that socio-economic disparities, including the educational status, lead to huge disparity in the space of healthcare.

As stated in another report, ‘About 38 million people in India (which is more than Canada’s population) fall below the poverty line every year due to healthcare expenses, of which 70 percent is on purchase of drugs’.

Thus, reduction of social inequalities ultimately helps to effectively resolve many important healthcare issues. Otherwise, mostly the minority population with adequate access to knowledge, social and monetary power will continue to have necessary resources available to address their healthcare needs, appropriately.

Regular flow of newer and path breaking medicines to cure and effectively treat many diseases has not been able to eliminate either trivial or dreaded diseases alike. Otherwise, despite having effective curative therapy for malaria, typhoid, cholera, diarrhea/dysentery and venereal diseases, why will people still suffer from such illnesses? Similarly, despite having adequate preventive therapy, like vaccines for diphtheria, tuberculosis, hepatitis and measles, our children still suffer from such diseases. All these continue to happen mainly because of socio-economic inequalities related considerations, including poor level of awareness.

A paper titled, “Healthcare and equity in India”, published in The Lancet (February, 2011) identifies key challenges to equity in service delivery, healthcare financing and financial risk protection in India.

These include: 

- Imbalanced resource allocation

- Limited physical access to quality health services and inadequate human resources for health

- High out-of-pocket health expenditures

- High health spending inflation

- Behavioral factors that affect the demand for appropriate healthcare

Research studies vindicate the point:

Following are some research studies, which I am using just as examples to vindicate the above argument on inequality adversely impacting healthcare:

• HIV/AIDs initially struck people across the socio-economic divide. However, people from higher socio-economic strata responded more positively to the disease awareness campaign and at the same time more effective and expensive drugs started becoming available to treat the disease, which everybody cannot afford. As a result, HIV/AIDS are now more prevalent within the lower socio-economic strata of the society.

• Not very long ago, people across the socio-economic strata used to consume tobacco in many form. However, when tobacco smoking and chewing were medically established as causative factors for lung and oral cancers, those coming predominantly from higher/middle echelon of the society started giving up smoking and chewing of tobacco, as they accepted the medical rationale with their power of knowledge. Unfortunately the same has not happened with the poor people of lower socio-economic status. As a consequence of which, ‘Bidi’ smoking and ‘Gutka’/tobacco chewing have not come down significantly among the population belonging to such class, with more number of them falling victim of lung and oral cancers.

Thus, in future, to meet the unmet needs when more and more sophisticated and high cost disease treatment options will be available, mostly people with higher socio-economic background will be benefitted more due to their education, knowledge, social and monetary power. This widening socio-economic inequality will consequently widen the disparity in the healthcare scenario of the country.

Phelan and Link in their research study on this subject had articulated as under:

“Breakthroughs in medical science can do a lot to improve public health, but history has shown that, more often than not, information about and access to important new interventions are enjoyed primarily by people at the upper end of the socioeconomic ladder. As a result, the wealthy and powerful get healthier, and the gap widens between them and people who are poor and less powerful.”

Recent deliberations at Davos:

In the last two decades, socio-economic inequality in India has been fuelled by rapid, but unequal economic growth of the nation. Though the overall standard of living has been rising, there still remain a large number of populations living in pockets of intense deprivation and abject poverty.

One of the Davos sessions of this year deliberated on “What Future Do You Want?” The session, among others, reportedly felt the important need to ensure people’s well being and put in place effective measures such as a social safety net and universal healthcare.

At the same WEF annual meet at Davos, United Nation’s Secretary General Ban Ki-Moon also reiterated, “All policies must be people centric. We should make a world where nobody is left behind.”

Conclusion:

Assuming the above approach as a sincere realization of the current policy makers and more importantly the powerful influencers of those policies, the key question that comes up is: In which direction would India now chart its course to address this critical issue?

One may possibly hazard a guess on the shape of the future policies to come in India from the BJP party President Amit Shah’s recent address to crème de la crème of Mumbai businessmen in a function organized by a business news channel. In this event Mr. Shah reportedly said to them that the BJP does not agree with their definition of “reforms” and will strive to build a welfare state.

Will this approach of the new political dispensation get reflected in the forthcoming union budget as well, to effectively translate the new National Health Policy of India into reality, at least this time?

I deliberated on the National Health Policy of India in my Blog Post of January 12, 2015, titled “India’s National Health Policy 2015 Needs Wings To Fly”

That said, if it really so happens, a strong signal would go to all stakeholders that India is now well poised to chart on an uncharted frontier to significantly reduce the impact of inequality, particularly in the space of healthcare.

In that process, despite the highest billionaire wealth concentration, India would set a pragmatic course to place itself at the top of the healthcare chart, not just in South Asia, but probably also within the BRIC countries, to expect the least.

Alzheimer’s Disease: Robs Memory: Steals Dignity: Escapes Treatment

Posted on by

At a well reputed Mumbai Club, quite unexpectedIy, I bumped into Sumeet (name changed). It has indeed been a long while since we met at his home in South Mumbai. He came there with his wife Shilpa (name changed). Sumeet, was literally an icon of yesteryears in every respect, a bright engineer with MBA and a much-accomplished leader of his time who retired at the turn of the new millennium.

“How are you Sumeet da?”, I started off cheerfully, as he was looking all around.

“Very well, very well and you?”, he replied softly with a faint quivering of his lips, but without any eye contact.

“I am good Sumeet da, but have you recognized me?” I queried with apprehension.

Turning his face towards Shilpa, Sumeet hesitatingly replied, “No. But have we met before?”

The innocent question struck me as lightning from nowhere, making me a bundle of emotion momentarily. With a lump in my throat and clenching my fists, I struggled hard to regain my composure.

Sumeet, one of the the brightest of brights, from earlier years of our generation, is now a victim of a dreaded illness called Alzheimer’s Disease (AD). The disease has robbed him of his priceless memory, changed his behavior beyond recognition, kidnapped him from his own self, and has stolen most of his much-valued dignity in life, mercilessly.

Alzheimer’s Disease (AD) in brief:

Alzheimer’s Disease (AD), as known to many, is the most common form of dementia, accounting for 60 to 80 percent of all cases, that results in serious memory loss and other intellectual and behavioral traits of individuals, serious enough to interfere with a person’s daily life and tasks.

AD has been defined as, a neurodegenerative type of dementia, in which the death of brain cells causes memory loss and cognitive decline. The total brain size shrinks with AD, as the tissue has progressively fewer nerve cells and connections. Brains affected by AD would always show tiny inclusions in the nerve tissue, called plaques and tangles.

Plaques are found between the dying cells in the brain – from the build-up of a protein called beta-amyloid, while the tangles are within the brain neurons and from a disintegration of another protein, called tau.

Though the abnormal protein clumps and inclusions in the brain tissues are always present in AD, there could be another underlying process also that is actually causing the disease, which scientists are not sure of, as yet.

Be that as it may, with the progression of the disease, besides memory loss, AD precipitates other serious symptoms, such as, deepening confusion about events, time and place; mood and behavior changes; unfounded suspicions about family, friends and even professional caregivers; disorientation; other behavior changes; then difficulty speaking, swallowing and walking. At a late stage, the patients lose the ability to carry on even a conversation and respond to their environment.

Cause:

Although the causes of AD are not quite clear to the scientists, as yet, the disease results from a combination of genetic, lifestyle and environmental factors that adversely affect the brain over a period of time.

Scientists opine that in less than 5 percent of the cases, the causative factors of the AD are specific genetic changes that can almost definitively indicate that a person would develop AD. According to published reports, while the strongest risk gene found so far is apolipoprotein e4 (APOE e4), other risk genes have not been conclusively confirmed, just yet.

Survival rate:

According to published reports, the survival rate of AD patients, after their symptoms become noticeable to others, can range from 4 to 20 years, depending on health conditions, the average being 8 years. In the United States, AD is the sixth leading cause of death.

Not a normal part of the aging process:

Although majority of people with AD are over 60 years of age, it is not just a disease of old age. Up to 5 percent of cases the disease may strike even younger people in 40s or 50s. Women are found to be more prone to AD than men.

Prevalence:

The World Health Organization (WHO) declared dementia, in general, as a priority condition in 2008, through the Mental Health Gap Action Program.

Each year, the total number of new cases of dementia worldwide has been reported as nearly 7.7 million, which means one new case every four seconds.

According to AC Immune SA of Switzerland, AD will be one of the biggest burdens of the future society showing dramatic incidence rates. Over 44 million people were now affected with AD worldwide. Since the incidence and prevalence of AD increase with age, the number of patients will grow dramatically as our society gets older. By 2050 the patient numbers are expected to triple, touching 135 million AD patients worldwide.

India:

According to another report titled, “Priority Medicines for Europe and the World – A Public Health Approach to Innovation” By Béatrice Duthey, Ph.D published on 20 February 2013, the fastest growth of AD in the elderly population is now taking place in China, India, and their south Asian and western Pacific neighbors and has become a major public health concern as the population ages.

AD is the most common kind neurodegenerative disease in India. There are reportedly around 5 million dementia patients in the country of which, roughly 70 to 80 per cent have AD. This number is expected to double by 2030, and the costs involved are expected to increase three times. Besides drugs, costs of ‘care giving’ for AD patients are also expected to rise significantly.

The market and economic impact:

According to AC Immune SA, AD market is currently estimated at US$ 5 billion annually and is expected to exceed US$ 20 billion by 2020.

The global economic impact of AD is shown by its worldwide cost of US$ 640 billion, exceeding 1 percent of gross world product. It can be seen as the most significant health crisis in the 21st century. The 2010 annual costs of treating and caring for patients was  $183 billion in the US alone. This figure is expected to increase to $ 1.1 trillion in 2015.

AD is becoming the third most expensive disease, counting for 30 percent of the US healthcare costs. The medical costs for Alzheimer´s Disease patients are three times higher than for other older patients. Moreover, AD patients mostly live at home resulting in high impact on family’s health, emotional well being, as well as their employment and financial security.

India:

Many elderly people in India live with AD without any treatment, accepting the condition as an unavoidable one and related to the aging process of an individual.

The present day costs of maintaining a patient with AD in India, who has been diagnosed, are reportedly any where between Rs. 50,000 to Rs. 4,50,000. Additionally, many elderly couples are just not frail and living alone these days, as their children may be working in a far off country.

Currently, AD market in India is reportedly around US$ 50 million, growing around 25 percent. More disease awareness initiatives are expected to accelerate the market growth by manifold. Sun Pharma is the market leader in the AD segment. Other, key players are Dr. Reddy’s Laboratories (DRL), Torrent, Glenmark, Ranbaxy, Cipla and Alkem

In fact, Cipla recently reportedly announced an investment of US$ 21 million in Chase Pharmaceuticals of the United States, which is an early-stage drug development company focused on developing novel approaches to improve treatments for Alzheimer’s disease.

In addition, DRL is also making rapid strides in this area. In 2013, the company launched generic Donepezil Hydrochloride tablets for AD in the US market.

Treatment:

There is no cure for AD as of date. There is no disease-modifying treatment for AD even in the global market, either.

Since 2003, there has not been any single innovative drug launched in the global market either for prevention or cure of AD. The available drugs cannot stop the progression of the disease. They just temporarily slow the worsening of dementia symptoms. The situation gets even more complicated as the disease is usually diagnosed late, when already 70 percent of the nerve cells in the brain are dead.

Global researchers are looking for new treatments to alter the course of the disease and improve the quality of life for people suffering from this dreaded disease.

For the treatment of AD, the U.S. Food and Drug Administration (FDA) has approved two types of medications, namely,

-      Cholinesterase inhibitors, such as, Aricept, Exelon, Razadyne, Cognex

-      Memantine, such as, Namenda to treat the cognitive symptoms (memory loss, confusion, and problems with thinking and reasoning) of the disease.

Many doctors prescribe both types of medications together, along with Vitamin E for cognitive changes.

However, Aricept is the only cholinesterase inhibitor approved to treat all stages of AD, from moderate to severe.

Although, Tacrine (Cognex) was the first cholinesterase inhibitor approved, very few doctors prescribe this drug today because of more serious side effects.

According to The Alzheimer’s Association, the world’s leading voluntary health organization in Alzheimer’s care, support and research; the current treatments for AD at a glance are as follows:

Treatments at a glance:

Generic Brand Approved For Side Effects
donepezil Aricept (Eisai/Pfizer) All stages Nausea, vomiting, loss of appetite and increased frequency of bowel movements.
galantamine Razadyne (Janssen) Mild to moderate Nausea, vomiting, loss of appetite and increased frequency of bowel movements.
memantine Namenda/Ebixa (Actavis/Lundbeck) Moderate to severe Headache, constipation, confusion and dizziness.
rivastigmine Exelon (Novartis) Mild to moderate Nausea, vomiting, loss of appetite and increased frequency of bowel movements.
tacrine Cognex (Pfizer) Mild to moderate Possible liver damage, nausea, and vomiting.
vitamin E Not applicable Not approved Can interact with antioxidants and medications prescribed to lower cholesterol or prevent blood clots; may slightly increase risk of death.

India:

In India the treatment is much the same. Besides, patented versions, relatively cheaper generic equivalents of all these drugs are available in the country.

On going drug trials: 

As there are no effective therapies for AD, this therapy segment remains at the top of the list for unmet needs, globally. Disease-modifying therapies could transform this market appreciably.

At the Alzheimer’s Association International Conference held in Copenhagen, Denmark from July 12 to 17, 2014, scientists described five trials that may prevent the onset of the neurodegenerative disease in people not yet experiencing cognitive decline, as follows:

  • Gantenerumab and Solanezumab: Two experimental drugs, , both of which are antibodies designed to bind to amyloid and prevent it from forming brain-damaging plaques.
  • Solanezumab: An experimental anti-amyloid compound.
  • The trial will first pilot a screening test for two genes to see if it can accurately predict risk of mild cognitive impairment. The next phase of the trial will test an experimental compound designed to delay symptoms of mild cognitive impairment and Alzheimer’s disease in people without symptoms.
  •  Crenezumab: Anti-amyloid antibody
  •  An immunotherapy that prompts the body’s immune system to produce antibodies against amyloid protein, and a beta-secretase inhibitor that blocks the production of certain forms of amyloid.

According to Alzheimer’s Disease Therapeutics and Diagnostics: World Market 2013-2023 the following global players hold greatest potential. In particular, the analysis investigates these companies:

• Pfizer
• Eisai
• Actavis
• Lundbeck
• Novartis
• TauRx Therapeutics
• AC Immune.

A large pharma industry association of the United States has indicated in a report that dedicated researchers are currently working on nearly 100 medicines in development for Alzheimer’s and other dementias. These could give future patients a new hope for a future free of AD.

Conclusion:

AD can strike anyone at any time without any visible warning whatsoever. It then robs the person’s memory, steals the individual’s dignity of life, evades all available current treatments, till it is able to extinguish slowly and agonizingly the last flicker of life, mostly much sooner than otherwise it would have been.

Like many other countries, India – the world’s 2nd largest population, is also facing a crisis in dealing with the growing number of AD patients.

These patients require constant support from family/professional caregivers along with medical attention. The progression of the disease leaves patients mostly in semi-vegetative states, at times for years.

If no cure is available for AD, arresting the disease progression becomes a major health challenge in the country. Currently only short term symptomatic treatment is available. Neither is there any organized mechanism for early diagnosis of AD with specific markers, which could lead to early intervention with the most appropriate and effective drugs to address the disease sooner.

Alzheimer’s Disease that turns millions of otherwise boisterous individuals, like Sumeet, into living dead, snatching away everything that a life would possibly demand at its minimum, must feature in the areas of focus of the new national heath policy of India under the new dispensation.
