Personalized Medicine – why the sudden popularity?

Posted by cdavenport on Thursday Nov 12, 2009 Under Blog, Personalized medicine

The dream of tailor-made medication is not a new one, but the prospective cost of such treatments has always been a barrier to growth.  Simply put, the return on compounds that only treat small populations cannot justify the investment.  With life expectancy increasing and the cost of health care rising, however, an economic imperative is driving the change from managing sickness to managing wellness.   A wellness-management approach detects conditions early, and hence the level of reversibility is high;  the current reactive model has lower reversibility.  With drugs targeted toward specific populations, the importance  and acceptance of in silico modeling would increase.  The author presumes that drug development programs will run more quickly, and that regulatory bodies would be able to approve drugs much earlier once a response in the target population has been proven.  This is anticipated to reduce the clinical development time line and lead to cheaper drugs and prolonged exclusivity.

With the trend towards a lower acceptance of risk and thus bigger and more expensive clinical trials, do you agree with the author’s assumptions, especially given a smaller target population?

    hate to be cliche, but it must be about the money!

    Below is an excerpt from New Development in the race for cheap and fast genome sequencing – see details at [|leo://plh/http%3A*3*3www%2Efuturemedicine%2Ecom*3doi*3full*310%2E2217*3pme%2E09%2E46/cP2Z?_t=tracking_disc ]

    A new DNA sequencing technology by Pacific Biosciences (CA, USA) called single molecule real-time (SMRT) sequencing, due to be commercially released in 2010, is expected to increase the speed of genome sequencing and very economical (hoped to achieve a price tag of US$100 per genome and be able to sequence DNA 20,000 times faster than second-generation sequencers that are currently available on the market). They quote the original source as 2009 Industrial Physics Forum Annual Meeting: [|leo://plh/http%3A*3*3www%2Eaapm%2Eorg*3meetings*309AM*3IPForum%2Easp/yHcs?_t=tracking_disc ]

    Pretty good amount of information in wikipedia (Yes, it is not a peer-reviewed journal, but it is a good for an overall review for those, and they give lots of references one can check out): [|leo://plh/http%3A*3*3en%2Ewikipedia%2Eorg*3wiki*3Personalized_medicine/YYCP?_t=tracking_disc ]

    Does politics have anything to do with the popularity of personalized medicine?

    Quote from this:

    “The infrastructure of laws, policy, education and clinical practice is being built around personalized medicine to support its use:

    ▪ Medical institutions and governments around the world have announced their commitment to putting personalized medicine into practice through dedicated centers or state-wide initiatives.

    ▪ Personalized medicine approaches are becoming ‘best practice’ in hospitals, in order to guarantee that patients with serious conditions, such as cancer, are given optimum therapy from the start.

    ▪ The regulatory system in the USA is integrating genetic testing into the labels of pharmaceutical products, ensuring that a drug is administered in a way that minimizes the risk of adverse effects and improves the chances of effective treatment.

    ▪ Nearly every major pharmaceutical development project is incorporating information on genetic variation and its effects on the safety and effectiveness of the candidate drug.

    ▪ Leading medical schools in the USA and elsewhere are launching genomics-based medical education programs to train the next generation of care providers.

    ▪ Personalized medicine applications have extended beyond cancer to improve treatments in cardiovascular disease, infectious diseases, psychiatric disorders, and transplantation medicine.”

    Why would drugmakers want tests that reveal that some people won’t be helped by their drugs?

    In “The Era of Personalized Medicine by Katherine Hobson”, Edward Abrahams answers this as follows: ” That used to be a common view, but no longer. Drug companies have come to understand that putting safer and more efficacious drugs on the market serves their interests more than failed drugs, and they’ve embraced the principles of personalized medicine. There have been any number of drugs withdrawn from the market because of adverse events for a small minority of people. If you knew [who’d suffer side effects] in advance, that could be avoided.”

    The Coriell Personalized Medicine Collaborative (a longitudinal research study designed to determine the utility of using personal genome information in health management and clinical decision-making.) is enrolling individuals in a research study to investigate the impact of personalized medicine on health outcomes.

    A non-academic thought: Don’t we live in an era where speed and individuality matters more than ever? Every other technology is using the personalized approach (mobile phones and other electronic gadgets to food). So may be “the time has come” for medicine also to be personalized more than ever before!
