The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion recommending the approval of GSK 2857916 (belantamab mafodotin), from GlaxoSmithKline, as monotherapy for the treatment of multiple myeloma in adult patients, who have received at least four prior therapies and whose disease is refractory to at least one proteasome inhibitor, one immunomodulatory agent, and an anti-CD38 monoclonal antibody, and who have demonstrated disease progression on the last therapy.
This is based on data from the pivotal DREAMM-2 (DRiving Excellence in Approaches to Multiple Myeloma) study including 13-month follow-up data. These data demonstrated that treatment with single-agent belantamab mafodotin, administered as a 2.5 mg/kg dose every three weeks (Q3W), resulted in an overall response rate of 32%. Median duration of response was 11 months and median overall survival was 13.7 months.
The safety and tolerability profile were consistent with previously reported data on belantamab mafodotin. The most commonly reported grade 3 or higher adverse events (occurring in more than 10% of patients) in patients receiving the 2.5 mg/kg dose were keratopathy / microcyst-like epithelial changes (MECs) (46%), thrombocytopenia (22%), anaemia (21%), lymphocyte count decreased (13%) and neutropenia (11%).
