Drug: Belantamab mafodotin frozen liquid Drug: Belantamab mafodotin lyophilized powder |
Enrollment | 221 |
Participant Flow
Recruitment Details | This was an open-label, randomized, multicenter study to evaluate the efficacy and safety of belantamab mafodotin monotherapy at a dose of 2.5 milligram per kilogram (mg/kg) or 3.4 mg/kg, given intravenously (IV) in participants with relapsed/refractory multiple myeloma (RRMM). |
Pre-assignment Details | A total of 221 participants were enrolled in this study. The results presented are based on the data cut-off date of 04 May 2022. Those participants still benefiting from study drug in the opinion of their treating physician continued to receive study drug in Post Analysis Continued Treatment (PACT) phase and their data will be reported after they stop receiving treatment as per protocol. |

---|---|---|---|
Arm/Group Description | Participants were administered frozen liquid (30 mg/vial solution in a single use vial) at a dose of 2.5 mg/kg GSK2857916 as IV solution once every three weeks for a maximum of up to 39 cycles (1 cycle= 21 days). Frozen liquid was diluted with 0.9 percent saline. | Participants were administered frozen liquid (30 mg/vial solution in a single use vial) at a dose of 3.4 mg/kg GSK2857916 as IV solution once every three weeks for a maximum of up to 32 cycles (1 cycle= 21 days). Frozen liquid was diluted with 0.9 percent saline. | Participants were administered lyophilized powder (100 mg/vial in a single use vial) at a dose of 3.4 mg/kg GSK2857916 given IV for a maximum of 35 cycles (1 cycle= 21 days). Lyophilized powder was reconstituted using water for injection. |
