A decade ago, receiving a medicine designed for your specific genetic makeup or modifying your own immune cells to fight cancer may have seemed like something out of a science fiction novel. But today, "precision" medicines — tailored therapeutics based on a patient's distinct genetic characteristics — are turning fiction into fact for many patients.
Since every person is unique, not only do precision medicines have the potential to bring highly effective therapies and high-value care to patients, they can also lower the overall cost of treating many of the most serious diseases. The investments needed to discover and develop these medicines can substantially improve health outcomes, and reduce the cost of failing to appropriately target treatment, estimated to be tens of billions of dollars every year.
Tailoring medical treatment to the profile of each patient can enable physicians to identify the best course of treatment and often avoid or reduce adverse drug reactions and the toxic effects of medicines that may not be necessary.
