Health care utilization and steroid-refractory toxicities from immune checkpoint inhibitors.

Anti-programmed death protein 1 (anti-PD-1) agents have transformed the treatment of advanced melanoma and other cancers, but the rates of steroid-refractory toxicities and health care utilization are not well described. This study assessed these endpoints in patients with melanoma treated with anti-PD-1 with or without ipilimumab.
