MADRID (Reuters) - Merck & Co's drug Keytruda, the first in a new wave of immune-boosting medicines to be approved for treating melanomas in the United States, also has potential in stomach cancer, new research shows.

Early clinical trial results reported on Sunday mean that gastric, or stomach cancer can be added to a growing list of tumor types where so-called immunotherapy may have an important role to play.

Keytruda belongs to a drug class designed to help the body's own immune system fend off cancer by blocking a protein known as Programed Death receptor (PD-1), or a related target PD-L1, used by tumors to evade disease-fighting cells.

On Sept. 4 it became the first drug of this type to win U.S. approval, although rivals including Bristol-Myers Squibb, Roche and AstraZeneca are working on similar products."
