Final OS analyses from the TOURMALINE- MM3 and -MM4 RCTs of ixazomib maintenance in newly diagnosed multiple myeloma.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
TOURMALINE-MM3 (NCT02181413) and -MM4 (NCT02312258) were phase 3 studies of fixed-duration, single-agent ixazomib maintenance in post-transplant (TOURMALINE-MM3)/transplant-ineligible (TOURMALINE-MM4) patients with newly diagnosed multiple myeloma (NDMM) that demonstrated improved median progression-free survival (PFS) for ixazomib vs placebo. We present the final overall survival (OS) analyses for each study separately. In both studies, eligible patients were randomized 3:2 to receive ixazomib maintenance (3 mg [cycles 1-4], 4 mg [from cycle 5 if tolerated]) or matching placebo for ≤26 cycles, or until progressive disease/unacceptable toxicity. At median follow-up of approximately 8 years (TOURMALINE-MM3) and 5 years (TOURMALINE-MM4), median OS was not reached in either arm in MM3 (hazard ratio [HR], 1.025; 95% confidence interval [CI], 0.789-1.332; p = 0.850), and was 64.8 (ixazomib) vs 69.5 (placebo) months in MM4 (HR, 1.090; 95% CI, 0.861-1.381; p = 0.473). No new safety signals were identified in either study; incidence of new primary malignancies was low. Despite meeting their primary endpoints (PFS), neither final OS analysis of TOURMALINE-MM3/-MM4 showed statistically significant differences between fixed-duration ixazomib maintenance and placebo in patients with NDMM. The growing number of available, highly effective salvage treatments with novel mechanisms of action make demonstrating an OS advantage in front-line myeloma studies increasingly challenging.
