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 21-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\^3accompanied by clinically significant bleeding, any Grade 3 or greater non-hematologic toxicity, any Grade 3 or greater non-hematologic laboratory value if: laboratory abnormality persists for \>48 h despite supportive treatment for abnormality leads to hospitalization, Grade 4 Corneal toxicity, and liver toxicity meeting pre-specified GlaxoSmithKline liver stopping criteria. DLTs were assessed by National Cancer Institute- Common Toxicity Criteria for Adverse Events (NCI-CTCAE), version 4.03.

Analysis population: DLT Evaluable population included participants fulfilling the 'All Treated' population (all eligible participants who received at least 1 dose of study treatment) criteria, and those who received a complete infusion in 21- day Cycle 1.

Groups in this outcome

Main Study - Part 1: Belantamab Mafodotin 2.5 Milligram/ Kilogram (mg/kg)

Main Study - Part 1: Belantamab Mafodotin 3.4 mg/kg

Participants with RRMM received belantamab mafodotin as dose of 3.4 mg/kg via IV infusion on Day 1 of every 21-day cycle (Q3W) maximum up to disease progression.
