Patient‐reported health‐related quality of life from the phase III TOURMALINE‐MM1 study of ixazomib‐lenalidomide‐dexamethasone versus placebo‐lenalidomide‐dexamethasone in relapsed/refractory multiple myeloma
Bibliographic record
Abstract
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
