Abstract:
e14125 Background: Nivolumab and pembrolizumab, two anti-PD1 agents, were approved and funded in Québec since 2016 for non small cell lung cancer (NSCLC), renal cell carcinoma (RCC) and melanoma. The objectives were to describe and assess the “real-life” use, efficacy and security of nivolumab and pembrolizumab in NSCLC, RCC and melanoma in the general population. Methods: Medical records of every patient who received nivolumab or pembrolizumab between January 1 st 2011 and October 31 st 2017 were reviewed retrospectively. Data analysis cut-off was Dec 31 st 2017. Results: In total, 532 patients received at least one dose of anti-PD1 during the study period. Median number of doses received varied for each indication (medians varied from 4 to 9.5). Adverse events were pooled together by drug. 47.7 % of patients receiving pembrolizumab suffered from any grade immune-related adverse event (IRAE), most of them of grade 1 or 2. 12.2 % of patients reported grade 3-4 IRAE. Most of the patients reported only one type of IRAE. For nivolumab, 44.6% of patients presented with any IRAE, including 8.3% of grade 3-4. Dermatologic IRAE were more frequent in the melanoma patients whereas gastrointestinal and pulmonary IRAE were more frequent in NSCLC patients. Treatment discontinuation due to adverse events varied from 6 to18% depending on indication. Conclusions: Nivolumab and pembrolizumab seemed less effective and caused more IRAE in “real-life” population than in the pivotal clinical trials. Caution and regular follow-up are warranted when using these drugs in general population. Longer follow-up is needed.[Table: see text]
