Positive headline results from a planned analysis of Phase 3 trial investigating Jemperli plus standard-of-care chemotherapy.

GSK today announced positive headline results from a planned analysis of Part 1 of the RUBY/ENGOT-EN6/GOG3031/NSGO phase III trial investigating Jemperli (dostarlimab) plus standard-of-care chemotherapy (carboplatin and paclitaxel), followed by dostarlimab as a single agent, compared to placebo plus chemotherapy followed by placebo in adult patients with primary advanced or recurrent endometrial cancer.

The trial met its primary endpoint of overall survival (OS), demonstrating a statistically significant and clinically meaningful benefit in the overall patient population.

Hesham A. Abdullah, MD, MSc, SVP, Global Head Oncology, R&D, GSK, said: “With today’s headline results from Part 1 of the phase III RUBY trial, dostarlimab plus chemotherapy has become the only immuno-therapy combination to show a survival benefit in this broader patient population in this treatment setting. We look forward to sharing detailed results of this analysis with regulatory authorities and the larger scientific community.”

Full results from this latest analysis from the trial will be published in a medical journal and presented at an upcoming scientific meeting.
