The most common adverse events experienced by patients who received MK-3475 included fatigue, rash, diarrhea, nausea, cough, joint pain, fever and itching. Seven MK-3475 related Grade 3/4 adverse events were reported as potentially “immune related.”
Merck recently initiated a global, randomized, Phase II clinical trial to evaluate MK-3475 versus standard chemotherapy for participants with advanced melanoma whose disease has progressed after prior therapy (reference: NCT01704287). Participants will be randomized to receive one of two doses of MK-3475 or investigator-choice chemotherapy. For further information, please visit http://www.clinicaltrials.gov.
About PD-1 and MK-3475
Research has shown that PD-1, an immune checkpoint receptor, helps to confer immune resistance for some cancers allowing tumor cells to grow and proliferate unchecked. MK-3475 is a monoclonal antibody designed to target PD-1 to disrupt the role PD-1 plays in resisting the immune system.About Merck Today's Merck is a global healthcare leader working to help the world be well.
