Keytruda is a prescription drug approved by the U.S. Food and Drug Administration (FDA) to treat cancers including classic Hodgkin lymphoma and primary mediastinal B-cell lymphoma. Keytruda is indicated in cases where other drug therapies have previously been tried. Keytruda is also known by its drug name, pembrolizumab.
