Health-related quality of life outcomes from the CANDOR study in patients with relapsed or refractory multiple myeloma

CANDOR (NCT03158688) compared carfilzomib, dexamethasone, and daratumumab (KdD) to carfilzomib and dexamethasone (Kd) in patients with relapsed/refractory multiple myeloma (RRMM). A secondary objective of CANDOR was to evaluate health-related quality of life (HRQoL) scores using the Global Health Status (GHS)/Quality of Life (QoL) domain of the EORTC QLQ-C30. Scores were compared between KdD and Kd using a restricted maximum likelihood-based mixed effects model for repeated measures. GHS/QoL completion rates were81% for both arms. Higher GHS/QoL scores were observed with KdD versus Kd from Cycle 7-26. The overall least squares mean estimate (95% CI) of the difference between treatment arms was 0.06 (-2.39 to 2.50
