Hossein Borghaei, DO, discusses the significance of the 2-year follow-up results of the CheckMate-057 and -017 studies, the evolving role of PD-L1 as a biomarker and others that are in development, and emerging immunotherapy agents in the field of non-small cell lung cancer.

Melissa Johnson, MD, associate director, Lung Cancer Research, Sarah Cannon Research Institute, discusses the phase II BIRCH study, which is examining atezolizumab (Tecentriq) in patients with PD-L1–positive locally advanced or metastatic non–small cell lung cancer (NSCLC).

Pembrolizumab demonstrated an objective response rate of 18% in data from two clinical trials exploring the PD-1 inhibitor as a treatment for patients with pretreated recurrent or metastatic head and neck squamous cell carcinoma.

Keith T. Flaherty, MD, discusses choosing between immunotherapy and targeted therapy in the frontline setting for patients with BRAF-mutated melanoma.

The PD-L1 inhibitor avelumab demonstrated durable responses and promising early survival data for patients with pretreated metastatic Merkel cell carcinoma.

Pembrolizumab (Keytruda) is associated with an exceptional overall response rate in patients with relapsed/refractory Hodgkin lymphoma.

Robert Ferris, MD, PhD, vice chair for Clinical Operations, associate director for Translational Research, and coleader of the Cancer Immunology Program at the University of Pittsburgh Cancer Institute, discusses the CheckMate-141 trial, which found that treatment with single-agent nivolumab (Opdivo) reduced the risk of death by 30% and doubled 1-year overall survival (OS) rates compared with investigator's choice of therapy for patients with recurrent or metastatic head and neck squamous cell carcinoma (SCCHN).

At a minimum follow-up of 18 months, the combination of nivolumab and ipilimumab reduced the risk of disease progression by 58% compared with ipilimumab alone, and single-agent nivolumab lowered the risk of progression by 45% versus ipilimumab monotherapy in patients with advanced melanoma.
