Opdivo inhibits a protein that prevents the body's immune system from attacking melanoma tumors, the FDA said in a news release.
The drug's safety and effectiveness were evaluated in clinical studies involving 120 people with melanoma that had either spread or couldn't be removed by surgery. Some 32 percent of people who took the drug had their tumors shrink, and this effect lasted for more than six months in about one-third of these people, the FDA said.
Common side effects included rash, itching, cough, respiratory infection and fluid retention. More serious adverse reactions included immune system impairment involving the lung, colon, liver or kidneys, the FDA said.
Opdivo is marketed by Bristol-Myers Squibb, based in Princeton, N.J.
