37MO Dostarlimab plus chemotherapy in primary advanced or recurrent endometrial cancer (pA/rEC) in the RUBY trial: Overall survival (OS) by MMR status and molecular subgroups
Notice bibliographique
Résumé
At interim analysis (IA) 1 of Part 1 of the RUBY trial (NCT03981796), statistically significant benefit in PFS was observed with dostarlimab+carboplatin-paclitaxel (D+CP) vs placebo (PBO)+CP in the overall and mismatch repair deficient/microsatellite instability-high (dMMR/MSI-H) populations of pts with pA/rEC. Here we report OS from IA2. Pts with pA/rEC were randomized 1:1 to D+CP or PBO+CP followed by D or PBO for ≤3 years or until progression. OS was a dual-primary endpoint in the overall population and a prespecified, exploratory analysis in the dMMR/MSI-H and mismatch repair proficient/microsatellite stable (MMRp/MSS) populations. OS by molecular subgroup was a post-hoc analysis. Safety was a secondary endpoint. 494 pts were randomized (245 D+CP; 249 PBO+CP). In the overall population, there was a significant reduction in the risk of death by 31% and clinically meaningful improvement of 16.4 mo in median OS (mOS) for D+CP vs PBO+CP (Table). In the dMMR/MSI-H population, hazard ratio (HR) for OS was 0.32; mOS was not reached for D+CP and was 31.4 mo for PBO+CP. In the MMRp/MSS population, HR for OS was 0.79; mOS was 34.0 mo for D+CP and 27.0 mo for PBO+CP. At IA2, in 400 pts with whole exome sequencing, a trend towards clinical benefit with D+CP was observed in the dMMR/MSI-H, TP53 mutated, and no specific molecular profile subgroups.

Mut, mutant; NR, not reached; NSMP, no specific molecular profile. D+CP showed statistically significant and clinically relevant OS benefit in the overall population compared with CP alone. A substantial survival difference was seen in the dMMR/MSI-H population. In the MMRp/MSS population, there was a 7 mo difference in median OS vs CP alone, with a 21% risk reduction for death. OS by molecular subgroup at IA2 was consistent with IA1. RUBY is the only trial to demonstrate a statistically significant OS benefit in pts with pA/rEC and supports the use of dostarlimab+CP as a standard of care in the 1L setting.
