TOURMALINE‐MM1 is a phase III, randomized, double‐blind, placebo‐controlled study of ixazomib plus lenalidomide and dexamethasone (IRd) versus placebo‐Rd in patients with relapsed/refractory multiple myeloma following 1–3 prior lines of therapy. The study met its primary endpoint, demonstrating significantly longer progression‐free survival (PFS) in the IRd arm versus placebo‐Rd arm (median 20.6 vs 14.7 months, hazard ratio 0.74, P = .01), with limited additional toxicity. Patient‐reported health‐related quality of life (HRQoL) was a secondary endpoint of TOURMALINE‐MM1. The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core‐30 (QLQ‐C30) and Multiple Myeloma Module 20 (QLQ‐MY20) were completed at screening, the start of cycles 1 and 2, every other cycle, the end of treatment, and every 4 weeks until progression. Over median follow‐up of 23.3 and 22.9 months in the IRd and placebo‐Rd arms, mean QLQ‐C30 global health status (GHS)/QoL scores were maintained from baseline over the course of treatment in both groups, with no statistically significant differences between groups. EORTC QLQ‐C30 function domain scores were also generally maintained from baseline; similarly, physical, emotional, and social function domains were maintained with IRd versus placebo‐Rd, with slightly higher mean change from baseline scores at earlier time points with IRd. Findings from this double‐blind study demonstrate that addition of ixazomib to Rd significantly improved efficacy while HRQoL was maintained, reflecting the limited additional toxicity seen with IRd versus placebo‐Rd, and support the feasibility of long‐term IRd administration.
