Trial overview
Official title: A phase 2, randomized, parallel, open-label study to investigate the safety, efficacy, and pharmacokinetics of various dosing regimens of single-agent Belantamab Mafodotin (GSK2857916) in participants with relapsed or refractory multiple myeloma (DREAMM-14)
Trial description: This study aims to evaluate alternative dosing regimens of single-agent belantamab mafodotin in participants with relapsed or refractory multiple myeloma (RRMM) to determine if an improved overall benefit/risk profile can be achieved by modifying the belantamab mafodotin dose, schedule, or both.

Inclusion and exclusion criteria
Inclusion criteria:
- Participant must be 18 years of age inclusive at the time of signing the informed consent form (ICF).
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.
- Histologically or cytologically confirmed diagnosis of MM and a. Has undergone stem cell transplant or is considered transplant ineligible, and b. Has failed at least 3 prior lines of anti-myeloma therapies, including an anti-cluster of differentiation (CD)38 antibody (e.g., daratumumab) alone or in combination and is refractory to an immunomodulatory agent (e.g., lenalidomide, pomalidomide) and a proteasome inhibitor (e.g., bortezomib, ixazomib, carfilzomib).
- France specific: participants have failed at least 4 prior lines of anti-myeloma therapies
- Participant has measurable disease per modified IMWG criteria.
- Life expectancy of at least 6 months, in the opinion of the investigator.
- Male and female participants agree to abide by protocol-defined contraceptive requirements.
- Participant is capable of giving signed informed consent.
- Participant meets country-specific inclusion criteria described in the protocol.
Exclusion criteria:
- Symptomatic amyloidosis, active POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, myeloma protein, and skin changes), or active plasma cell leukemia at the time of screening.
