Popis: e15114 Background: Associations between obesity and cancer risk, prognosis, and therapeutic outcomes have been extensively researched. However, the impact of BMI on safety in patients receiving immunotherapy has not been well described. Methods: A descriptive, retrospective analysis examined associations between BMI (kg/m2) (underweight/normal, BMI < 25; overweight, 25 ≤ BMI < 30; obese, BMI ≥ 30) and incidence of any-grade and grade 3/4 immune-mediated adverse events (imAEs) in patients receiving ≥ 1 dose of nivolumab 3 mg/kg as monotherapy (NIVO3; n = 2746). Data were pooled from CheckMate clinical trials across 8 tumor types. Data from nivolumab in combination with ipilimumab cohorts (n = 1026) and safety analyses by specific imAEs and tumor types will be presented. Results: Select NIVO3 monotherapy cohort patient demographics were: 68.5% male, median age of 61 years, median 10 doses received, and median BMI of 25.3 kg/m2. Results showed a trend towards higher incidence of any-grade, but not grade 3/4, imAEs in obese vs overweight and obese vs underweight/normal BMI patients (Table). BMI associations with imAE incidence were consistent with the overall trend across pre-defined subsets, including smoking status, age, and ECOG performance status. Both male and female patients had an increased incidence of any-grade imAEs with obesity; however, obese female patients had a higher incidence of grade 3/4 imAEs vs underweight/normal BMI (Table). Conclusions: This was a novel analysis of BMI and safety in 2746 patients across 8 tumor types in CheckMate clinical trials who were treated with nivolumab monotherapy. While obese patients showed a trend towards higher incidence of any-grade imAEs than those with overweight and underweight/normal BMI, incidence of grade 3/4 imAEs was consistent across BMI categories.
