Long-term immune-related adverse events frequent after PD-1 inhibitor use in patients with melanoma
Long-term immune-related adverse events (IRAE) are frequent in patients with melanoma treated with PD-1 inhibitors (anti-PD1), especially when IRAEs have previously occurred, according to a presentation at the 2020 American Society of Clinical Oncology (ASCO) Virtual Scientific Program.
In 119 patients with advanced melanoma who had received anti-PD1 monotherapy at least 2 years prior to the start of the study, IRAEs occurred in 83%, including severe IRAEs in 30%. In 43% of patients, long-term IRAEs occurred, resulting in the hospitalization of 4% of these patients.
Among patients with long-term IRAEs, 87% had experienced IRAEs within the first 2 years of treatment with anti-PD1.
