A Study to Investigate the Safety and Efficacy of Belantamab for the Treatment of Multiple Myeloma When Used as Monotherapy and in Combination Treatments (DREAMM-20)
May 21, 2026 updated by: GlaxoSmithKline
A Phase 1/2 Open-label, Multicentre, Dose Escalation and Expansion Study to Investigate the Safety, Tolerability, and Clinical Activity of Belantamab as Monotherapy and in Combination With Other Treatments in Participants With Multiple Myeloma
The study consists of three parts:
- Part 1 The primary purpose of this part aims to evaluate the safety, tolerability, and clinical activity of escalating doses of single agent Unconjugated belantamab antibody in participants with refractory multiple myeloma (RRMM) who have received at least 3 prior therapies (4L+).
- Part 2 The primary purpose of this part is to evaluate the safety, tolerability, and clinical activity of different dose ratios of belantamab mafodotin in combination with Unconjugated belantamab antibody (delivered as separate drugs) in participants with RRMM who have received at least 3 prior therapies (4L+).
- Part 3: The Primary purpose of this part will evaluate the clinical activity of a selected dose of the unconjugated belantamab antibody, either alone or in combination with belantamab mafodotin alongside the standard of care (SoC) pomalidomide-dexamethasone backbone. The study will focus on patients with multiple myeloma who have undergone at least one prior line of therapy, including treatment with lenalidomide.

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
YES
IPD Plan Description
Qualified researchers may request access to anonymized individual patient-level data (IPD) and related study documents of the eligible studies via the Data Sharing Portal.
Details on GSK's data sharing criteria can be found at: https://www.gsk.com/en-gb/innovation/trials/data-transparency/
IPD Sharing Time Frame
Anonymized IPD will be made available within 6 months of publication of primary, key secondary and safety results for studies in product with approved indication(s) or terminated asset(s) across all indications.
IPD Sharing Access Criteria
Anonymized IPD is shared with researchers whose proposals are approved by an Independent Review Panel and after a Data Sharing Agreement is in place.
Access is provided for an initial period of 12 months but an extension may be granted, when justified, for up to 6 months.
