What was measured

DLT is an adverse event (AE) that is considered by the investigator to be clinically relevant and attributed to the study therapy during the 28 day DLT period and meets at least one of the DLT criteria: Grade 3 or greater febrile neutropenia lasting \>48 hours (h) despite adequate treatment; Grade 4 thrombocytopenia \<25,000/mm\^3 accompanied by significant bleeding; any Grade 3 or greater non-hematologic laboratory value (if laboratory abnormality persist \>48 h despite supportive treatment or abnormality leading to hospitalisation); non-hematologic toxicity which does not resolve with appropriate supportive treatment within 48 h, Grade 4 corneal adverse events; and other organ specific toxicities (liver toxicity that causes discontinuation of treatment).

Analysis population: DLT-evaluable population included participants who received at least 1 full dose of belantamab mafodotin and at least 75% of planned doses of Len/Dex by the end of Cycle 1 (Day 28). As pre-specified in protocol, only specified treatment arms were planned to be analyzed for DLTs.

Groups in this outcome

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

Participants with RRMM received belantamab mafodotin as SINGLE full dose of 1.9 mg/kg on Day 1 of every 28-day cycle as a 30-60 minute infusion. Along with belantamab mafodotin, Lenalidomide was administered as 25 mg or 10 mg PO on Days 1-21 of each 28-day cycle with 40 mg Dexamethasone weekly PO/ IV on Days 1, 8, 15 and 22 of each cycle.

Main Study Phase: Belantamab Mafodotin 2.5mg/kg SPLIT + Len/Dex

Participants with RRMM received belantamab mafodotin as two equal divided doses of a total 2.5mg/kg dose as a 1.25 mg/kg dose on Day 1 and a 1.25 mg/kg dose on Day 8 of each 28-day cycle as a 30-60 minute infusion. Along with belantamab mafodotin, Lenalidomide was administered as 25 mg or 10 mg PO on Days 1-21 of each 28-day cycle with 40 mg Dexamethasone weekly PO/ IV on Days 1, 8, 15 and 22 of each cycle.

Main Study Phase: Belantamab Mafodotin 2.5mg/kg SINGLE + Len/Dex

Participants with RRMM received belantamab mafodotin as SINGLE full dose of 2.5 mg/kg on Day 1 of every 28-day cycle as a 30-60 minute infusion. Along with belantamab mafodotin, Lenalidomide was administered as 25 mg or 10 mg PO on Days 1-21 of each 28-day cycle with 40 mg Dexamethasone weekly PO/ IV on Days 1, 8, 15 and 22 of each cycle.
