Personalized medicine (PMx), medical treatment tailored to specific patient populations based on their genetic or molecular biology profiles, has long been heralded as the next big thing in healthcare. It’s been about 16 years since Genentech launched Herceptin, a drug for breast cancer patients with a specific genetic mutation. At the time, Herceptin seemed to usher in a revolution for how drugs would be developed and patients would be cured.
In that new version of care, drugs could be tailored to a patient’s specific biochemical profile, dramatically improving efficacy rates and reducing the system-wide costs and complications associated with one-size-fits-all medications. For pharmaceutical manufacturers, this approach had the potential to improve sales and profits through a radically new business model: differentiated products for segmented populations (see “A Strategist’s Guide to Personalized Medicine,” by Avi Kulkarni and Nelia Padilla McGreevy, s+b, Winter 2012).
