“Neoadjuvant treatment with the combination of nivolumab (Opdivo) and ipilimumab (Yervoy) demonstrated almost a tripling in objective response rate (ORR) compared with the PD-1 inhibitor alone but at the cost of significant added grade 3 adverse events (AEs) for patients with high-risk resectable melanoma, according to a small study presented at the 2017 SITC Annual Meeting.
“In the combination arm (n = 11), the ORR was 73% and 50% of patients achieved a pathological complete response (pCR). With nivolumab alone (n = 12), the ORR was 25% and the pCR rate was 25%. Unfortunately, these gains in response were accompanied by 73% of patients in the combination arm having a grade 3 AE compared with just 8% in the single-agent arm. This high level of toxicity led the researchers to close the study early, according to Sangeetha M. Reddy, MD, MSci. Reddy worked on this trial with co-investigators Rodabe Amaria, MD, and Jennifer Wargo, MD.”
