Pushed by patient advocates who want earlier access to medications, the Food and Drug Administration has approved a flurry of oncology drugs in recent years, giving some people with cancer a renewed sense of hope and an array of expensive new options. A few of these drugs have been clear home runs, allowing patients with limited life expectancies to live for years.
Many more drugs, however, have offered patients only marginal benefits, with no evidence that they improve survival or quality of life, said Dr. Vinay Prasad, assistant professor of medicine at the Oregon Health and Sciences University, who has written extensively about the FDA's approval process for cancer drugs.
