Blenrep combinations in multiple myeloma application accepted for review by EMA: GSK

Hesham Abdullah, Senior Vice President, Global Head Oncology, R&D, GSK, said, “The milestone reinforces the potential for Blenrep to redefine outcomes for patients with multiple myeloma at or after first relapse. We are working to bring Blenrep to patients as quickly as possible given the high unmet need and the clinically robust effects of the Blenrep combinations in the DREAMM-7 and DREAMM-8 phase III head-to-head trials.”

The application is based on interim results from the DREAMM-7 and DREAMM-8 phase III trials, which both met their primary endpoints, showing statistically significant and clinically meaningful improvements in progression-free survival (PFS) for the belantamab mafodotin combinations compared to standard of care combinations in relapsed or refractory multiple myeloma. The DREAMM-7 trial is evaluating belantamab mafodotin combined with BorDex versus daratumumab plus BorDex, while the DREAMM-8 trial is evaluating belantamab mafodotin in combination with PomDex versus bortezomib plus PomDex.

A positive overall survival (OS) trend was observed in both trials but was not statistically significant at the time of interim analysis. Follow-up for OS continues. Results also showed clinically meaningful improvements across all other secondary efficacy endpoints, including deeper and more durable responses compared to the respective standard of care combinations. The safety and tolerability profiles of the belantamab mafodotin combinations in DREAMM-7 and DREAMM-8 trials were broadly consistent with the known profiles of the individual agents.
