Piotr Wysocki: Dostarlimab combined with chemotherapy in dMMR/MSI-H advanced endometrial cancer patietns

Piotr Wysocki recently posted on LinkedIn:

“Part 1 of the RUBY trial (NCT03981796) evaluated the benefit of adding dostarlimab or placebo to standard first-line chemotherapy in patients with primary advanced or recurrent endometrial cancer. The study randomized 494 patients (1:1) to dostarlimab+carboplatin+paclitaxel (CP) or placebo+CP administered for 6 cycles, with maintenance dostarlimab or placebo administered for up to 3 years.

In the second intermin analysis, the study met the dual-primary endpoint for OS. In the general population, combining dostarlimab with CP significantly reduced the relative risk of death by 31% (HR=0.69; 95%CI 0.54-0.89).

The significant improvement in OS in the ITT population was driven by the benefit of dostarlimab in patients with dMMR/MSI-H tumors, where dostarlimab reduced the relative risk of death by 68% (HR=0.32; 95% CI 0.17-0.63).

Patients with pMMR/MSI-L tumors did not demonstrate significant improvement in OS (HR=0.79; 95% CI 0.60-1.04).

Despite significant improvement of PFS in both dMMR/MSI-H and pMMR/MSI-L populations, dostarlimab does not improve long-term outcomes in patients with advanced pMMR/MSI-L endometrial tumors.”
