DREAMM-20: This study aims to determine the recommended dose level, safety and effectiveness of a drug called belantamab when given alone and in combination with other treatments in people with multiple myelomaA 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

Clinical summary


This study has three parts.

Part 1 - Dose Escalation Phase in participants with relapsed or refractory multiple myeloma (RRMM): In this part, belantamab (bela) will be administered in participants with RRMM until progressive disease (PD). Participants may switch to Belamaf in case of PD.

Part 2 - Combination Treatments in participants with RRMM: In this part, participants with RRMM will receive Bela-xRd and Belamaf-xRd. The combination treatment xRd includes lenalidomide (R) and dexamethasone (d). x will be either a standard of care (SoC) or an emerging treatment for Multiple Myeloma.

Part 3 - Combination Treatments in participants with transplant-ineligible newly diagnosed multiple myeloma (TI-NDMM): In this part, participants with TI-NDMM will receive Bela-xRD and Belamaf-xRd.

  • PART 1: Participants who have received at least 3 prior lines of anti-myeloma treatments, and have already received an immunomodulating agent, a proteasome inhibitor, and an anti-CD38 mAb (unless contraindicated or unavailable).

  • Have documented disease progression during or after their most recent therapy
  • 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.
  • Participants capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the ICF and protocol.


  • Diagnosis of primary Amyloid Light chain (AL) Amyloidosis, active Polyneuropathy, organomegaly, endocrinopathy, myeloma protein, and skin changes (POEMS) syndrome, primary plasma cell leukemia.
