BACKGROUND: This study presents patient-reported outcomes (PROs) from the phase 1/2 BRUIN (NCT03740529) trial of pirtobrutinib monotherapy for the treatment of B-cell malignancies, including chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) and mantle cell lymphoma (MCL). METHODS: PROs were collected at each cycle using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and item library (IL) sets for CLL/SLL- and MCL-related symptoms and an Expanded Fatigue measure. Prespecified analyses included descriptive change from baseline, time to worsening (TTW) using Kaplan-Meier method, and longitudinal analyses using a mixed model for repeated measures. RESULTS: A total of 263 patients with CLL/SLL and 124 with non-blastoid MCL who received pirtobrutinib monotherapy after prior BTKi were included in the final PRO analysis. The proportion of patients with CLL/SLL who improved or remained stable from baseline through Cycle 31 remained above 80% for physical function (PF), CLL/SLL-related symptoms, fatigue, and global health status/quality of life (GHS/QoL). The proportion of patients with MCL who improved or remained stable through Cycle 20 remained above 70% for PF, MCL-related symptoms, fatigue, and GHS/QoL. Median TTW was not reached in either CLL or MCL. Longitudinal analyses for PF, CLL/SLL-related symptoms, fatigue, and GHS/QoL consistently met statistically significant and clinically-meaningful improvement from baseline...
