What was measured

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

Analysis population: Safety population.

Groups in this outcome

1.9 mg/kg Belantamab Mafodotin + 8 mg Feladilimab

Participants with Relapsed/Refractory Multiple Myeloma (RRMM) received 1.9 milligram (mg)/kilogram (kg) of belantamab mafodotin intravenous (IV) infusion in combination with 8 mg feladilimab IV infusion, given 1 hour after belantamab mafodotin end of infusion (EOI), once every 3 weeks (Q3W).

2.5 mg/kg Belantamab Mafodotin + 8 mg Feladilimab

Participants with RRMM received 2.5 mg/kg belantamab mafodotin IV infusion in combination with 8 mg feladilimab IV infusion, given 1 hour after belantamab mafodotin EOI Q3W.

2.5 mg/kg Belantamab Mafodotin + 24 mg Feladilimab

Participants with RRMM received 2.5 mg/kg belantamab mafodotin IV infusion in combination with 24 mg feladilimab IV infusion, given 1 hour after belantamab mafodotin EOI Q3W.
