Personalized medicine — the ability to tailor therapies to patients’ individual genetic characteristics — has long been the holy grail of the life sciences industry. The effort has produced a string of recent successes, including a host of drugs targeted to people with specific genetic profiles, the European approval of the world’s first gene therapy treatment, and a much-heralded leukemia treatment pioneered at Children’s Hospital of Philadelphia (CHOP) that uses tweaked versions of patients’ own cells to eliminate their cancer. While these advances are certainly exciting for patients, they raise a host of ethical, legal and financial challenges that people working in the field will need to address before personalized medicine can become a thriving business.
The challenges are so great, contends Wharton health care management professor Ezekiel J. Emanuel, that claims of a renaissance in medicine brought on by individualized approaches often seem hyperbolic. “Before we buy into this, we need to remember that almost every evaluation of what drives health care costs up points to new technologies,” says Emanuel, who is also a professor of medical ethics and health policy at Penn’s Perelman School of Medicine. “We need to be skeptical. We need to see the data before people buy into the idea that personalized medicine is going to produce cost savings and be so much better for the system.”
