- PART 3: Participants who meet both of the following:

- NDMM with a requirement for treatment as documented per IMWG criteria

- Not considered a candidate for high dose chemotherapy with ASCT due to:

1. Age = 65 years OR

2. Age 18-65 years with presence of comorbid condition(s) likely to have a negative
impact on tolerability of high-dose chemotherapy with ASCT or who refuse
high-dose chemotherapy with ASCT as an initial treatment.

Summary
Brief summary
The study consists of three parts

- Part 1: The primary purpose of this part is to determine the safety, and recommended
part 2 dose of belantamab (bela) in participants with relapsed or refractory multiple
myeloma (RRMM).

- Part 2: The primary purpose of this part is to determine safety, tolerability and
percentage of adverse events (AEs) that happen to eyes in participants with RRMM treated
with bela in combination with other treatments.

- Part 3: The primary objective of this part is to assess the safety, tolerability and
rate of ocular AEs in participants with transplant-ineligible newly diagnosed multiple
myeloma (TI-NDMM) treated with either belantamab mafodotin (belamaf) or bela in
combination with other treatments.
