GSK Blenrep Combos for Multiple Myeloma Accepted for EU Review

Read MoreHide Full Article

GSK plc (GSK - Free Report) announced that the European Medicines Agency (EMA) has accepted its marketing authorization application (MAA) seeking approval for the Blenrep (belantamab mafodotin) combination therapy to treat relapsed or refractory multiple myeloma (RRMM) for review.

The MAA seeks the approval of Blenrep in combination with J&J’s (JNJ - Free Report) Velcade (bortezomib) plus dexamethasone (BorDex) or Bristol Myers’ Pomalyst (pomalidomide) plus dexamethasone (PomDex) for the myeloma indication in the EU. Per GSK, the advisory committee to the EMA is scheduled to begin the review process soon to make a recommendation to the regulatory body regarding the potential authorization of the Blenrep combo therapy for RRMM in the EU.

The MAA for the Blenrep combo was supported by interim results from the phase III DREAMM-7 and DREAMM-8 studies, both of which met their primary endpoints of progression-free survival (PFS). In both studies, statistically significant and clinically meaningful improvements in PFS were observed for Blenrep combinations compared with standard care in RRMM patients.

Specifically, the DREAMM-7 study compared Blenrep/BorDex combo to J&J’s Darzalex (daratumumab) and BorDex combo, while the DREAMM-8 study compared Blenrep in combination with PomDex to J&J’s Velcade in combination with PomDex.

A positive trend was observed for a key secondary endpoint of overall survival (OS) in both phase III studies. However, such a trend was notstatistically significant at the time of the interim analysis, and follow-up for OS is ongoing.

Additionally, GSK reported clinically meaningful improvements in all secondary efficacy endpoints in the studies, including deeper and more durable responses compared with standard care combinations. The safety and tolerability of Blenrep combinations in these studies were generally consistent with the known profiles of the individual agents.

Year to date, shares of GSK have gained 6.2% against the industry’s 3% decline.

We remind investors that Blenrep was initially granted accelerated approval in the United States as a monotherapy for RRMM patients who had received at least four prior therapies in 2020, based on the results of the DREAMM-2 study’s overall response rate. The drug was also approved in the EU for the same indication on a conditional basis.

The final approval of the drug was contingent upon a confirmed clinical benefit from a randomized phase III study.

However, in November 2022, Blenrep was withdrawn from the U.S. market after the failure of GSK’s phase III confirmatory study, DREAMM-3, which evaluated Blenrep in patients with relapsed or refractory multiple myeloma. The study failed to meet its primary endpoint of PFS, thereby failing to meet the FDA’s Accelerated Approval regulations.

Consequently, Blenrep monotherapy as a treatment for RRMM was also withdrawn from the EU market.

The acceptance of the latest filing for Blenrep combinations to treat RRMM in the EU instills GSK’s hope of bringing the drug back to the European market for the patients soon, given the high unmet need.

MM is one of the most common forms of blood cancer, which is treatable but not curable. Per GSK, more than 180,000 new cases are diagnosed globally every year, with around 50,000 of these in the EU. As MM often becomes resistant to existing treatments, ongoing research into new therapies is essential.
