Serum samples were collected for the analysis of the presence of ADAs using validated immunoassays. All samples were tested in screening assay, and positive samples were further characterized for antibody titers.

Analysis population: Safety Population

Groups in this outcome

1.9 mg/kg Belantamab Mafodotin + 500mg Dostarlimab

Participants with Relapsed/Refractory Multiple Myeloma (RRMM) received 1.9 milligram (mg)/kilogram (kg) belantamab mafodotin intravenous (IV) infusion as powder for solution once every 3 weeks (Q3W) infused over 30- 60 minutes on day 1 of 21-day cycles in combination with 500 mg dostarlimab as a 30-minute IV infusion 1 hour after belantamab mafodotin end of infusion (EOI) on day 1 of 21-day cycles (Q3W).
