- Belantamab mafodotin accepted for accelerated assessment by the EMA's Committee for Human Medicinal Products (CHMP)

- Submission based on data from the pivotal DREAMM-2 study of immunoconjugate targeting B-cell maturation antigen (BCMA) recently published in The Lancet Oncology

LONDON, Feb. 3, 2020 /PRNewswire/ -- GlaxoSmithKline plc today announced that the European Medicines Agency (EMA) validated the marketing authorisation application (MAA) for belantamab mafodotin for the treatment of patients with relapsed or refractory multiple myeloma whose prior therapy included an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 antibody. Belantamab mafodotin was accepted for accelerated assessment by the EMA's Committee for Human Medicinal Products (CHMP).

Accelerated assessment is granted if the CHMP determines the treatment is of major interest from a public health perspective and represents a therapeutic innovation. Validation of the MAA confirms that the submission is accepted and begins the formal review process by the CHMP.

The MAA is based on data from the pivotal DREAMM-2 (DRiving Excellence in Approaches to Multiple Myeloma) study. Full results from the study, recently published in The Lancet Oncology, demonstrated a 31% overall response rate (ORR) with a 2.5 mg/kg regimen of single-agent belantamab mafodotin in heavily pre-treated patients with multiple myeloma who were refractory to an immunomodulatory drug and a proteasome inhibitor and were refractory and/or intolerant to an anti-CD38 antibody. The safety and tolerability profile was consistent with previously reported data on belantamab mafodotin.i

More than 48,000 people in the European Union were diagnosed with multiple myeloma in 2018.ii Belantamab mafodotin was granted PRIME designation in 2017 by the EMA, a programme that is intended to facilitate development of investigational medicines that have shown clinical promise for conditions where there is significant unmet need.

About multiple myeloma
Multiple myeloma is the second most common blood cancer and is generally considered treatable, but not curable.iii Research into new therapies is needed as multiple myeloma commonly becomes refractory to available treatments.iv

About B-cell maturation antigen (BCMA)
The normal function of BCMA is to promote plasma cell survival by transduction of signals from two known ligands, BAFF (B-cell activating factor) and APRIL (a proliferation-inducing ligand). This pathway has been shown to be important for myeloma cell growth and survival. BCMA expression is limited to B cells at later stages of development. BCMA is expressed at varying levels in myeloma patients and BCMA membrane expression is universally detected in myeloma cell lines.v

About the DREAMM clinical trial programme for belantamab mafodotin (GSK2857916)
Belantamab mafodotin is an investigational immunoconjugate comprising a humanised anti-B cell maturation antigen (BCMA) monoclonal antibody conjugated to the cytotoxic agent auristatin F via non-cleavable linker. The drug linker technology is licensed from Seattle Genetics; monoclonal antibody is produced using POTELLIGENT Technology licensed from BioWa.

Belantamab mafodotin is not currently approved for use anywhere in the world.
