GSK’s DREAMM-7 trial shows promising results for Blenrep in multiple myeloma

GSK plc has unveiled positive outcomes from the DREAMM-7 head-to-head phase III trial, evaluating Blenrep (belantamab mafodotin) as a treatment for relapsed or refractory multiple myeloma. This pivotal trial demonstrated a statistically significant progression-free survival (PFS) benefit for Blenrep combined with bortezomib and dexamethasone (BorDex) against the daratumumab plus BorDex regimen.

Trial Details and Efficacy of Blenrep

The DREAMM-7 trial was unblinded early based on the recommendation of the Independent Data Monitoring Committee (IDMC). The primary endpoint of progression-free survival was met, indicating Blenrep’s effectiveness in prolonging the time to disease progression or death compared to the current standard of care. Notably, a strong overall survival trend with a nominal p value < 0.0005 was observed.
