MK3475 Induced High Rates of Durable Responses in Advanced Melanoma

Healio | Jun 3, 2014

“A majority of patients with advanced melanoma who had and had not received previous ipilimumab demonstrated durable responses with the PD-1 targeted antibody MK-3475, according to study results presented at the ASCO Annual Meeting.

“ ‘This is the largest phase 1 clinical trial ever conducted in this disease, and together with a lung cancer cohort, this is the largest phase 1 trial ever done in oncology,’ study investigator Antoni Ribas, MD, PhD, professor of medicine at the David Geffen School of Medicine at the University of California in Los Angeles, said during a press conference. ‘These are early data, but they tell us we are on to something really important.’ ”

Editor’s note: The cancer drug MK-3475 is an immunotherapy, meaning that it boosts a patient’s own immune system to fight cancer. This story describes a clinical trial that tested MK-3475 on volunteer patients with advanced melanoma, and found good results for a majority of the patients. Some of the patients had previously been treated with the drug ipilimumab (Yervoy) and some had not; both kinds of patients benefited from MK-3475 in the trial.
