The double-blind, placebo-controlled Phase 3 TOURMALINE-MM1 study showed that ixazomib-lenalidomide-dexamethasone (ixazomib-Rd) regimen can significantly improve relapse/refractory multiples compared with placebo-Rd Progression-free survival of patients with myeloma
In this trial, patients were randomly assigned to ixazomib-Rd group (360 people) or placebo-Rd group (362 people), and based on the number of previous treatments (1 vs 2/3), proteasome inhibitor (PI ) Stratification of exposure history (yes vs.
Overall survival of the intention-to-treat population and different subgroups
Overall survival of the intention-to-treat population and different subgroupsAfter a median follow-up of 85 months, the median OS of the ixazomib-Rd group and the placebo-Rd group were 53.
A lower hazard ratio was observed in a predetermined subgroup, suggesting that the ixazomib-Rd regimen has a greater OS benefit compared with placebo-Rd.
Overall survival of patients with various high-risk cytogenetic characteristics
Overall survival of patients with various high-risk cytogenetic characteristicsAfter the study treatment, 71.
The new incidence of primary malignant tumors was similar in the two groups: ixazomib-Rd group (10.
In summary, in this analysis, the progression-free survival benefit of ixazomib-Rd and placebo-Rd did not translate into a statistically significant OS benefit
Subgroup of patients with poor prognostic factors can get greater OS benefit from ixazomib-Rd treatment Subgroup of patients with poor prognostic factors can get greater OS benefit from ixazomib-Rd treatment
