“Immunotherapy has led a transformation for melanoma care but combinations of anti–PD-1 and CTLA-4 agents are toxic and biomarkers are not available to help personalized treatment, calling for further research into less toxic and more effective options, according to a presentation by Caroline Robert, MD, PhD, at the 2017 World Congress of Melanoma.
“At this point, the only approved immunotherapy combination remains the PD-1 inhibitor nivolumab (Opdivo) and the CTLA-4 inhibitor ipilimumab (Yervoy). However, research into combination approaches is now focusing on triplets of anti–PD-1 therapies and new checkpoints, such as IDO. Additionally, ongoing research continues to search of a biomarker of response for immunotherapy in melanoma.”
