‘Made-to-Measure’ Marketing for ‘Made-to-Measure’ Medicines

Posted on by

We have entered into a new era of innovation in medical science where ‘one size fits all’ type of treatment is making a sizeable space for a new ‘made-to-measure’ variety of the same. Such medicines are being developed particularly for life-threatening and rare diseases, where individual genetic differences in patients play a key role in the choice of therapy.

The marketers of such drugs, at the same time, will need to make sure that the right sets of messages are delivered to the right person, in the right way and at the right time, for brand success. This isn’t a piece of cake, as it will be akin to finding out a needle from a haystack. It would call for craftily ferreting out from an enormous database, both the patients’ and the prescribers detail profile virtually in each stage of the treatment process.

Such information would form the bedrock for effective brand value creation and its delivery, to achieve best possible business results and also patient outcomes. Thus, ‘made-to-measure’ marketing would be a whole new ball game for many pharma marketers – a  completely different situation that, very often, they know little about.

In this article, I shall dwell on this subject. Let me begin with a brief description of the emerging ‘made-to-measure’ variety of treatments.

‘Made-to-measure’ treatment:

There are many serious and life-threatening disease conditions where ‘One Size Fits All’ sort of treatment approach doesn’t work too well. One such dreaded disease is cancer. Conventionally, following standard treatment guidelines, doctors generally opt for similar treatment for patients suffering from the same type and stage of cancer. Interestingly, it has been conclusively established over a period of time that this approach often yields different outcomes to different patients.

With the progress of genetic science, the researchers have unraveled this mystery from the genetic difference of patients. This understanding heralded the dawn of a new era of targeted or ‘made-to-measure’ drug therapies. These are called “personalized medicine” or “precision medicine”. According to the National Research Council, “personalized medicine” is an older term with a meaning similar to “precision medicine.”

Personalized medicines:

According to the American Society of Clinical Oncology (ASCO), understanding a patient’s genetic makeup and ascertaining how certain gene changes during cancerous tumor growth, doctors can now choose more effective treatment options for each patient. In other words, based on genetic test results, oncologists can now opt for a customize treatment, based on each patient’s specific needs. Such drugs can block or turn off the signals that tell malignant cells to grow and divide, keep cells from living longer than normal, or kill the cancer cells altogether.

Moreover, by performing genetic tests both on the cancer and normal cells, doctors can also:

  • Find out the chances of a person developing cancer and selecting the screening strategies to lower the risk
  • Match patients with treatments that are likely to be more effective and cause fewer side effects
  • Predict the risk of recurrence, which means the return of cancer

The new era began in 1998:

The era of ‘personalized medicine’ for cancer, in all practical purposes, commenced in 1998, when the US-FDA approved the targeted therapy, Herceptin (trastuzumab). Breast cancer patients having high levels of a biomarker, known as “HER-2,” are more likely to be susceptible to this drug.

Since then, the development of targeted therapies has grown rapidly. As reported by the American Journal of Managed Care (AJMC), published on January 31, 2018, one in every 4 drugs approved by the US-FDA over the past 4 years was a personalized medicine, and the agency approved a record-breaking 16 personalized therapy in 2017. The same year, US-FDA also approved the first biosimilar of a personalized medicine - trastuzumab-dkst (Ogivri) for HER-2-positive breast cancer patients. This biosimilar was developed with Herceptin as its reference.

The February 2018 report of Research and Markets titled, ‘Personalized Medicine – Scientific and Commercial Aspects’ says, the aim of ‘personalized medicine’ is to match the right drug to the right patient and, in some cases, even to design the appropriate treatment for a patient according to his/her genotype. I deliberated on genotype-based treatment in my article titled, ‘A Disruptive Innovation to Fight and Cure Intractable Diseases’, published in this blog on October 30, 2017.

At this point, let me hasten to add that the development of personalized medicine raises some ethical issues, as well. Currently, this debate is mostly limited to the area of genetic testing.

Personalized dosage:

An article published on March 23, 2015 in the ‘FDA Voice’ of the US-FDA states, since the 1990s, the agency is also working on personalized drug dosing. This is because individuals differ in how they eliminate a drug. Some eliminate it much more slowly than most other people, and thus are susceptible to overdosing, while others eliminate it much faster, and may not get the desired therapeutic effect. There are biomarkers to identify people who may have these unusual results. Personalized drug dosing makes sure that drug efficacy for such patients are not compromised, or they are not at high risk of any severe side effects.

Marketing ‘personalized medicine’ a whole new ball game:

All this vindicates that ‘personalized medicine’ is not just a flash in the pan. With each passing year, it’s moving ahead at a brisk pace. In this emerging scenario, what happens to marketing of these drugs? Will the marketing of ‘personalized medicine’ remain just the same as the conventional one, or it warrants radically different cerebral inputs?

The opportunities for personalization in pharma marketing are immense. ‘Personalized medicines’ offer a greater scope in leveraging its potential that is yet to be fathomed, meaningfully. Broadly, this will mean targeting customers or potential consumers even at the individual level, to add greater differential value.

This, in turn, will involve making the marketing content, the message format and choosing the effective value delivery platforms, virtually ‘made-to-measure’ for the target audience. Marketing interaction of this ilk, has proven to offer a cutting-edge experience to the target groups with greater outcomes, in tandem, yielding superior financial results to the concerned pharma players.

Recent reports:

On December 18, 2017, Cambridge BioMarketing – one of the world’s leading rare disease agency highlighted, as personalized medicine continues to take hold, it will be more important than ever for healthcare companies to incorporate the ‘hyperpersonalized’ experience in marketing and communications. Patients’ voice has already started becoming more important than ever before, in various facets of pharma business. In 2018, one may expect to witness more pharma companies tapping the experts who can help explain the life-changing benefits of a treatment for the patient, effectively – the report predicted.

Moving forward, patients embarking on new treatments will be better empowered to take charge of their well-being. Physicians and nurses will also be better connected to their patients, along with other care providers, with the support of enhanced digital connections and mobile apps. Interestingly, one can find it happening in several developed countries, especially, in areas like rare diseases, where ‘personalized medicines’ will be used more – underscored this agency.

On January 22, 2018, quoting the same Cambridge BioMarketing, FiercePharma also reported, more ‘personalized medicines’ also mean more ‘personalized marketing’ – and the ‘hyperpersonalization’ trend goes to extremes. Crunching data gathered from multiple sources, such drug marketers need to identify small groups that could be receptive to specific messaging. Advanced data and analytics, would facilitate the marketers to whittle down their targets and tailor messages to consumer audiences, sometimes as small as one person – the report asserted.

Conclusion:

As the February 2018 report of ‘Research and Markets’ highlights, increase in efficacy and safety of treatment by individualizing it, has benefitted in financial terms too. Available information indicates that ‘personalized medicine’ will ultimately be cost-effective in healthcare systems. This would also eliminate the need for various assumptions in the process of diagnosing a disease.

Thus, conventional pharma marketing based on the mostly segmentation strategy used for blockbuster molecules may not work for a ‘personalized medicine’. Instead, ‘personalized marketing, focused on smaller and exclusive markets – identified based on robust research and analytical data, will be the name of the new game for business excellence in this specialized area.

Thus, I reckon, as we move ahead, ‘made-to-measure’ marketing will no doubt be one of the key success requirements to make ‘made-to-measure’ medicines’ – a money spinner.

Cancer Care: Dawns A New Era Of Precision Medicine In India

Posted on by
Reply

The concept of ‘Precision Medicine’ has started gaining increasing importance, in the treatment process of many serious diseases, such as cancer. It is now happening in many countries of the world, including India.

The National Institutes of Health (NIH) of the United States, describes ‘Precision Medicine’ as:

“An emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle for each person.”

This is quite in contrast to the widely practiced “one-size-fits-all” type of drug treatment approach, where disease treatment and prevention strategies are developed for the average person, with less consideration for the differences between individuals.

It continues, irrespective of the fact that the same drug doesn’t always work exactly the same way for everyone. It can be difficult for a physician to predict, which patient will benefit from a medication and who won’t, besides having any advance inkling on who will experience Adverse Drug Reactions (ADR) with it, and who will not.

Whereas, the treatment path of ‘Precision Medicine’ allows doctors to predict more accurately which treatment and prevention strategies will work most effectively for a particular disease, and in which groups of people. This is mainly because, ‘Precision Medicine’ looks at the root cause of the ailment for each patient.

For example, in cancer care, use of the term ‘Precision Medicine’ would mean a treatment process for patients with similar tumors, that has been immaculately worked out in accordance with their unique genetic, physical, psychosocial, environmental, and lifestyle factors. Thus, especially for the treatment of life-threatening diseases, a gradual shift from “one-size-fits-all” types of medicines to ‘Precision Medicines”, could bring a new hope of longer survival or remission, for many such patients.

For example, in precision cancer care, it is all about analyzing a patient’s tumor to determine with specificity what drug or combination of drugs will work best with least side effects for that particular individual.

In this article, I shall focus on the development, use and benefits of ‘Precision Medicine’ in cancer, especially in India.

Not a radically new concept:

Several examples of ‘Precision Medicine’ can be found in a few other areas of medicine, as well, though its use in everyday health care is not very widespread, as on date.

One such example can be drawn from the blood transfusion area. A person requiring it, is not given blood from a randomly selected donor. To minimize the risk of any possible post-transfusion related complications, the blood for transfusion is selected only after scientific confirmation that the donor’s blood type matches to the recipient.

Difference between ‘Precision’ and ‘Personalized’ Medicines:

There is a significant overlap between these two terminologies. According to the National Research Council (NRC) of the United States, ‘Personalized Medicine’ is an older term having a meaning similar to ‘Precision medicine’, but may not always be exactly the same.

This change was necessitated as the term ‘Personalized’ could be interpreted to imply that treatments and preventions are being developed uniquely for each individual. Whereas, in ‘Precision Medicine’, the focus is on identifying which approaches will be effective for which patients based on genetic, environmental, and lifestyle factors, as stated above. The NRC, therefore, preferred the term ‘Precision Medicine’ to ‘Personalized Medicine’ to avoid such confusions or misunderstandings. Nevertheless, these two terms are still being used interchangeably.

Another terminology – ‘Pharmacogenomics’ is also used by some, in the same context, which is, in fact, a part of ‘Precision Medicine’. According to National Library of Medicine, United States, Pharmacogenomics is the study of how genes affect a person’s response to particular drugs. This relatively new field combines pharmacology (the science of drugs) and genomics (the study of genes and their functions) to develop effective, safe medications and doses that will be tailored to variations in a person’s genes.

Global initiatives taking off:

Currently, in various parts of the world, there are many initiatives in this area. However, one singular state sponsored initiative, I reckon, is exemplary and stands out.

According to NIH, in early 2015, President Obama announced a research effort focusing on bringing ‘Precision Medicine’ to many aspects of health care. The President’s budget for fiscal year 2016 included US$216 million in funding for the initiative for the NIH, the National Cancer Institute (NCI) – the NIH institute focused on cancer research, and the Food and Drug Administration (FDA).

‘The Precision Medicine Initiative’ has both short-term and long-term goals:

  • The short-term goals involve expanding precision medicine in the area of cancer research. Researchers at the NCI hope to use this approach to find new, more effective treatments for various kinds of cancer based on increased knowledge of the genetics and biology of the disease.
  • The long-term goals focus on bringing ‘Precision Medicine’ to all areas of health and healthcare on a large scale.

The market:

According to a July 2016 research report by Global Market Insights, Inc., the ‘Precision Medicine’ market size was over US$39 billion in 2015, and has been estimated to grow at 10.5 percent CAGR from 2016 to 2023, expanding the market to US$ 87.79 billion by end 2023.

The demand for ‘Precision Medicine’ is expected to significantly increase, specifically in cancer treatments, and also would be driven by advancements in new healthcare technologies, and favorable government regulations, in this area.

Faster US regulatory approval:

According to an August 15, 2016 article, published in the ‘MedCity News’ – a leading online news source for the business of innovation in health care, companion diagnostics, this trend is gaining currency as novel drugs are being paired up with tests that determine which patients will have a higher chance of responding to that drug.

This is vindicated by an expert analysis of a recent study, which found that the probability of a drug approval jumped three-times to 25.9 percent of those drugs that were approved with a predictive biomarker, from 8.4 percent for drugs without one.  This means a threefold increase in success, as determined by FDA registration, if any pharma or biologic drug company had a predictive marker in its new product development strategy. This indication would expectedly encourage more drugs to come with companion diagnostics than without, as the analysis underscored.

The National Institutes of Health (NIH) of the United States defines ‘Biomarkers’ or ‘Biological Markers’ as, “a characteristic that is objectively measured and evaluated as an indicator of normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention.”

‘Precision Medicine’ in India:

In the Indian health care space, ‘Precision Medicine’ is still in its nascent stage. This is despite its need in the country being high, especially while treating life threatening ailments, such as cancer, with greater precision, predictability and, therefore, more effectively than at present.

In several focus group studies too, the local medical specialists have also concurred with the global estimation of the inherent potential of ‘Precision Medicine’, as it rapidly evolves in India, particularly for use in oncology.

Local research:

Studies related to ‘Precision Medicine’ have already commenced, though in a modest scale, in a number of Government research centers, such as, Centre for Cellular and Molecular Biology (CCMB), Indian Council of Medical Research (ICMR), National Institute of Biomedical Genomics (NIBMG) and Institute of Genomics & Integrative Biology (IGIB).

Some large Government Hospitals too, like, All India Institute of Medical Sciences (AIIMS), National Institute of Mental Health and Neurosciences (NIMHANS), and even in Tata Memorial Hospital are making good progress in this area.

Local potential and market impact:

In March 2016, a leading daily of India had reported with examples that oncologists have started using ‘Precision Medicine’, in the country.

In this report, a molecular geneticist was quoted saying, “We see patients with blood, breast, lung, and colon cancer being referred for genetic testing on a routine basis. This testing is either for predictive purposes or for precision medicine guidance, where genetic tests are increasingly being used to determine which drug may be used for treatment.”

“We have had more than a few cases where patients respond well after being put on a new drug based on the results of these tests,” the expert said.

According to a May 2016 report of the Indian Council of Medical Research (ICMR), in the year 2016, the total number of new cancer cases is expected to be around 14.5 lakh (1.5 million), and the figure is likely to reach nearly 17.3 lakh (1.7 million) of new cases in 2020.

Over 7.36 lakh (736,000) people are expected to succumb to this disease in 2016 while the figure is estimated to shoot up to 8.8 lakh (880,000) by 2020. The data also revealed that only 12.5 percent of patients come for treatment in early stages of the disease.

Taking note of this fast ascending trend, it would be quite reasonable to expect that treatment with ‘Precision Medicine’, using advanced genetic profiling, would catch up, and grow proportionally in some section of the population, sooner than later. This trend is expected to keep pace with the commensurate increase in the anti-cancer drug market of India.

In tandem, the demand for preventive measures, especially, for cancer, cardiovascular, psychosomatic and many chronic metabolic diseases at the onset or prior to even onset stages, based on genome-based diagnostics, are also expected to go north. This would primarily be driven by increasing health awareness of the younger generation of India.

The spin-off commercial benefits for the pharma and diagnostic players in India, competing in these segments, could well be a significant boost even in the market potential of the older generic drugs in new patient groups, prompted by many out-of- box diagnostic and disease treatment strategies.

Another interesting article on genomic diagnostics for ‘Precision Medicine’, published on March 15, 2016 by ‘Pistoia Alliance’ – a global, not-for-profit alliance in life science that aims at lowering barriers to innovation in R&D, also expressed similar views regarding the future potential of ‘Precision Medicine’ in India.

Some key strategic steps:

Taking proactively some key strategic steps for business planning and development by the domestic pharma and diagnostic players, is now more important than ever before. This may call for developing some critical studies that would accelerate working out novel strategies for ‘Precision Medicine’ in India, besides obtaining required regulatory approvals in the coming years. The studies may include, among others:

  • Detailed analysis of target patient populations
  • Their genetic makeup for different types, or sub-types of diseases
  • Addressable sub populations
  • Their current treatment strategies, costs, affordability and differentiated value offerings of each, if any.

Conclusion:

Genomic research in India is now mainly directed towards routine genome-based diagnostics for a number of conditions, mostly for cancer. The country needs to encourage taking rapid strides to first sharpen and then gradually broaden this area, in various ways, for more effective and predictable treatment outcomes with ‘Precision Medicine’. As on date, most of such studies are carried out in the United States and Europe.

Alongside, a robust regulatory framework is required to be put in place, for wider usage of ‘Precision Medicine’ in India, without causing any concern to stakeholders. Government should also explore the need of clearly defining, and putting in place transparent, patient-friendly and robust Intellectual Property (IP) policies in the ‘Precision Medicine’ related areas to encourage innovation.

Healthcare expenditure being out-of-pocket for a vast majority of the population in India, the additional cost to be incurred for genomic sequencing tests, still remains a huge concern for many. Nevertheless, the good news is, many players have now gradually started entering into this area, spurring a healthy competition. This process would also gain accelerated momentum, as we move on.

This is just a dawn of a new era of ‘Precision Medicine’ in India. Its rapid development, is expected to be driven by a large number of startups, equipped with state-of-art technology, and hopefully, with greater health insurance penetration and the support from the Government. All this would bring the ‘Precision Medicine’ treatment cost affordable to a sizeable section of the population in the country, particularly for the treatment of cancer. The evolving scenario appears to be a win-win one, both for the patients, as well as the pharma and diagnostic players in India.

A Patient-Centric State Initiative To Revolutionize Disease Treatment

Posted on by
Reply

In his State of the Union address, just before the recent visit to India in January 2015, President Barack Obama articulated the need to develop “Precision Medicine” in his country – a bold, giant and perhaps unprecedented State initiative to remarkably improve effectiveness of disease treatment.

To set the ball rolling, in his budget proposal for the year 2016, President Obama earmarked an amount of US$ 215 million for this purpose. This includes an allocation of US$130 million for the National Institutes of Health (NIH) to create a national research database of about a million American volunteers by studying their genetics together with other relevant factors, such as the environments they live in and the microbes that live in their bodies.

‘Precision Medicine’ initiative is similar to path breaking 13-year and US$3 billion Human Genome Project, that has formed the bedrock of modern genomics, President Obama said. He also expressed hope that the private healthcare sector too, including universities and foundations, will get involved to “lay the foundation” for this new initiative of the Government for the interest of patients.

Why is this approach so relevant in today’s healthcare?

In an article published in the ‘British Medical Journal (BMJ) in October 2012, Richard Smith - an editor of BMJ until 2004 and a Director of the United Health Group’s chronic disease initiative wrote:

“Doctors know that many of the patients they treat with drugs will not benefit. Many patients know that too.”

Dr. Smith also emphasized, for centuries medicine classified diseases by what could be seen, felt, and smelt. Thereafter, medical scientists in this area started defining diseases anatomically, physiologically, and biochemically. Even today, this is by and large the paradigm where most medicines fall.

Smith underscored, because of imprecise diagnosis the treatment also becomes haphazard. There is big variation in how individuals respond to drugs and yet that variation is not usually recorded. The regulators approve drugs based on their average performance even today.

The White House release also reiterates, most medical treatments have been designed for the “average patient.” This “one-size-fits-all-approach,” treatments can be very successful for some patients but not for others.

This calls for broadening the scope of disease treatment – from the conventional and error-prone ‘Disease Oriented’ approach, to relatively more unconventional and better targeted with greater value – ‘Patient-Centric’ ones, wherever needed.

Two current trends:

To address this key deficiency in the effective treatment of several dreaded diseases for many patients, following two are the current trends, as stated by William Pao, M.D., Ph.D., who led Roche’s Oncology Discovery & Translational Area research unit since May 2014:

  • We now know that on a molecular level every cancer is different – not only between different tumors, but even between different areas within a single tumor! This means that we need to match the right drug to the patient who we know will respond best to the drug, at the right time during the course of treatment.
  • Patients will have their tumors profiled not only for genetic drivers, but also for predictive immunotherapy markers at different time points in their course of treatment.

Personalized and Precision Medicine:

The above trends in the endeavor of making treatments more patient specific – thus more effective, have thrown open scientific discourse and intense research on ‘Personalized’ and ‘Precision’ medicines.

As Pfizer has described in its website:

Personalized Medicine is a unique approach to medical practice in which the individual aspects of a patient are directly considered to guide treatment planning, including his or her genetic make-up, key biomarkers, prior treatment history, environmental factors and behavioral preferences. This approach can be used to optimize pharmaceutical treatments and overall care.

Whereas, Precision Medicine is an approach to discovering and developing medicines and vaccines that deliver superior outcomes for patients, by integrating clinical and molecular information to understand the biological basis of disease. Precision medicine is the biopharmaceutical research and development paradigm that will help enable more patient-centered clinical practice, including treatment decision-making based on genetic information – an emerging standard now often described as “personalized medicine”.

As President Obama said while announcing the proposal on January 30, 2015, ‘Precision Medicine’ promises delivery of the right treatment at the right time, every time, to the right person.

He also said that the new effort will “bring us closer to curing diseases like cancer and diabetes…and give all of us access to the personalized information we need to keep ourselves and our families healthier.”

‘Precision Medicines’ Dominate Oncology segment: 

In the European Society for Medical Oncology (ESMO) 2014 Congress, pharma majors reported their latest advances on precision medicines in the cancer care. Bristol-Myers Squibb, Roche, AstraZeneca, GlaxoSmithKline (GSK), and Merck & Co. were among the companies presented updates of their most promising cancer drugs closer to this area.

According to a large pharma lobby group in the United States – The Pharmaceutical Research and Manufacturers of America (PhRMA):

“Recent advances in diseases such as cancer and cystic fibrosis are delivering on the promise of targeted treatments, and between 12 and 50 percent of all compounds currently being researched by the industry are potential personalized medicines. These advances hold great promise in improving patient outcomes and controlling costs by targeting the right medicines to the right patients.”

‘DCAT Connect’ Report of September 2014 also indicates significant increase in ‘Precision Medicines’ in the pipelines of the leading global pharma companies, which is a key change over the past decade.

In 2013, targeted therapies increased their share of the global oncology market, accounting for 46 percent of total sales, up from 11 percent a decade ago. According to IMS Institute for Healthcare Informatics, the global oncology drug market reached US$ 91 billion in 2013 with CAGR of 5.4 percent from 2008 to 2013.

Taking note of this trend, it appears that in the near future ‘Precision Medicines’ would possibly be the most promising class in the treatment of cancer, particularly in breast cancer, lung cancer and certain types of leukemia. This is mainly because medical scientists are already quite acquainted with the molecular signatures of different types of cancer related tumors.

Medical scientists and researchers are also working on ‘Precision Medicines’ to more effectively address many other diseases, such as, diabetes, cardiovascular and ailments related to several types of infections.

Increasing potential:

Realization of the potential of ‘Precision Medicines’ to improve care and speed the development of new treatments has just only begun to be tapped.

In recent times, scientists and researchers have accelerated efforts to understand more about biomarkers for this purpose. A study conducted by the German Association of Research-Based Pharmaceutical Companies (vfa) indicates that more than 20 percent of clinical trials carried out since 2005 focused not just on agents, but also on biomarkers. Before 1990, only one in twenty clinical trials addressed biomarkers.

According to another report, last year, 20 percent of all new drug approvals in the United States were for “Precision Medicine” treatments. This vindicates, yet again, the immense potential to turn genetic discoveries into innovative disease treatments for patients.

A bold state sponsored research initiative:

State funded, ‘Precision Medicine’ initiative is a bold new step of the American Government to revolutionize improvement in healthcare and treating disease. It is expected to pioneer a new model of patient-powered research that promises to accelerate biomedical discoveries and provide clinicians with new tools, knowledge, and therapies to select which treatments will work best for which patients.

As the White House release reiterates, most medical treatments have been designed for the “average patient.” As a result of this, “one-size-fits-all-approach” treatments can be very successful for some patients but not for others. This is changing with the emergence of ‘Precision Medicine’, an innovative approach to disease prevention and treatment that takes into account individual differences in people’s genes, environments, and lifestyles.

In this process, ‘Precision Medicine’ gives clinicians tools to better understand the complex mechanisms underlying a patient’s health, disease, or condition, and to better predict which treatments will be most effective.

Opposite view:

In an op-ed titled, ‘Moonshot’ Medicine Will Let Us Down, published recently in The New York Times, the author argued with his differing viewpoints.

I am quoting below three of those arguments:

  • “For most common diseases, hundreds of genetic risk variants with small effects have been identified, and it is hard to develop a clear picture of who is really at risk for what. This was actually one of the major and unexpected findings of the Human Genome Project. In the 1990s and early 2000s, it was thought that a few genetic variants would be found to account for a lot of disease risk. But for widespread diseases like diabetes, heart disease and most cancers, no clear genetic story has emerged for a vast majority of cases.”
  • “Another unexpected finding of the Human Genome Project was the problem of ‘missing heritability.’ While the statistics suggest that there is a genetic explanation for common conditions and diseases running in families or populations, it turns out that the information on genetic variants doesn’t explain that increased risk.”
  • “The idea behind the “war on cancer” was that a deep understanding of the basic biology of cancer would let us develop targeted therapies and cure the disease. Unfortunately, although we know far more today than we did 40-plus years ago, the statistics on cancer deaths have remained incredibly stubborn.”

I am sure, you will analyze the above points with the facts that you have at your disposal on this subject to arrive at a logical conclusion.

Current Applications:

Though these are still early days, initial benefits of ‘Precision Medicines’ have been reported in many areas, such as:

  • Genetic analysis of patients dealing with blood clots: Since 2007, the U.S. Food and Drug Administration has been recommending genotyping for all patients being assessed for therapy involving Warfarin.
  • Colorectal cancer: For colon cancer patients, the biomarker that predicts how a tumor will respond to certain drugs is a protein encoded by the KRAS gene, which can now be determined through a simple test.
  • Breast cancer: Women with breast tumors can now be effectively screened to determine which receptors their tumor cells contain.
  • Cystic fibrosis: In America, patients with a rare form of cystic fibrosis now can choose a drug designed specifically to target the genetic defect causing their illness. Specialized medical centers, such as “individualized medicine centers” at the Mayo Clinic, are also available to the patients for effective treatment.

Ethical issues:

While following this pursuit of excellence of the genetic scientists in the realm of disease treatment, some experts have reportedly raised flags of caution. They strongly feel that DNA code sequencing brings to light a “very real privacy concerns” of individuals.

GeneWatch UK is an organization that investigates how genetic science and technologies will impact on our food, health, agriculture, environment and society. They have been strongly arguing, if genome sequencing is extended to entire population, individuals and their relatives could then be identified and tracked by matching their DNA with the genome stored in the respective health records. This move, as contemplated by them, could “wipe out privacy” with an impact on the society.

Thus, the ethical and social issues in the development of ‘Precision Medicine’ primarily in the area of genetic testing need to be effectively addressed, sooner.

Conclusion:

The quest for moving away from conventional and error-prone ‘Disease Oriented Treatment’ paving the way for unconventional and value added individual patient-specific ones, may soon come to fruition.

Advances in ‘Precision Medicine’ have already led to powerful new discoveries and several new treatments that are tailored to specific characteristics of individuals, such as a person’s genetic makeup, or the genetic profile of an individual’s tumor.  This is leading to a transformation in the way the world can treat diseases such as cancer.

Patients with breast, lung, and colorectal cancers, melanomas and leukemia, for instance, should be provided with facilities in specialist hospitals to undergo molecular testing as a part of patient care, enabling physicians to select treatments that improve chances of survival and reduce exposure to adverse effects.

Although, the potential for precision medicine to improve care and speed the development of new treatments has only just begun to be tapped, some skeptics do say that tailoring medical treatments to individual characteristics of each patient is both overly optimistic and cost-prohibitive.

Be that as it may, in the balance of probability the benefits of prudent use of ‘Precision Medicine’ far outweigh the concerns expressed. This evolving new paradigm would help saving not just significant expenses, but also precious time that is usually spent on ‘trial-and-error treatments’, by enabling clinicians to determine quickly which therapies are most likely to succeed.

Though lot many grounds would still need to be covered in this area, the State sponsored ‘Precision Medicine’ initiative of America to revolutionize disease treatment, in my view, is indeed a laudable one, every way.
