What was measured

Blood samples were collected for PK analysis. PK parameter was determined using standard non-compartmental methods.

Analysis population: Pharmacokinetic (PK) population. Only those participants with data available at specified time points have been analyzed.

Groups in this outcome

Main Study Phase: Belantamab Mafodotin 1.9 mg/kg STRETCH + Bor/Dex

Participants with RRMM received belantamab mafodotin as 1.9 mg/kg dose on Day 1 of every alternate 21-day cycle (C1, C3, C5, C7, and so on) as a 30-60 minute infusion. Along with belantamab mafodotin, Bortezomib (Bor) was administered as 1.3 milligrams per square meters (mg/m\^2) subcutaneously (SC) /IV on Days 1, 4, 8, and 11 with 20 mg Dexamethasone (Dex) PO/IV on Days 1, 2, 4, 5, 8, 9, 11, and 12 of every 21-day cycle up to 8 cycles.

Main Study Phase: Belantamab Mafodotin 1.9 mg/kg SINGLE + Bor/Dex

Participants with RRMM received belantamab mafodotin as SINGLE full dose of 1.9 mg/kg on Day 1 of every 21-day cycle as a 30-60 minute infusion. Along with belantamab mafodotin, Bortezomib was administered as 1.3 mg/m\^2 SC /IV on Days 1, 4, 8, and 11 with 20 mg Dexamethasone PO/IV on Days 1, 2, 4, 5, 8, 9, 11, and 12 of every 21-day cycle up to 8 cycles.
