French researchers tested 655 patients with advanced melanoma for the trial. The patients were already given other cancer treatments.
On average, the patients lived two years, and 40 percent of them are alive three years later. Sixty-one patients stopped taking the drug after their tumors went away — virtually all them are still in remission.
