Study of Belantamab Mafodotin Plus Standard of Care (SoC) in Newly Diagnosed Multiple Myeloma (DREAMM 9)

July 22, 2022 updated by: GlaxoSmithKline

A Phase 1, Randomized, Dose and Schedule Evaluation Study to Investigate the Safety, Pharmacokinetics, Pharmacodynamics and Clinical Activity of Belantamab Mafodotin Administered in Combination With Standard of Care in Participants With Newly Diagnosed Multiple Myeloma

This study will evaluate the safety, pharmacokinetics, pharmacodynamics and clinical activity of belantamab mafodotin in combination with Velcade (bortezomib), Revlimid (lenalidomide), dexamethasone (VRd) and will determine recommended phase 3 dose (RP3D) in adult participants with newly diagnosed multiple myeloma (NDMM). Participants will receive the combination of bortezomib, lenalidomide and dexamethasone (VRd) on a 3-week cycle until cycle 8, followed by the combination of lenalidomide and dexamethasone (Rd) on a 4-week cycle thereafter as per dosing schedule. Participants will receive belantamab mafodotin on a schedule that is dependent on the cohort to which they are assigned. Belantamab mafodotin will be administered in combination with VRd every 3 weeks (Q3W), every 6 weeks (Q6W), or every 9 weeks (Q9W) to Cycle 8, and then in combination with Rd every 4 weeks (Q4W), every 8 weeks (Q8W), or every 12 weeks (Q12W) thereafter. Participants will complete an End of Treatment (EOT) visit at the point of study treatment discontinuation, followed by a Safety Follow-up visit 70 days after EOT.

  • Sex and Contraception/Barrier Requirements (Female):
  • Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least 1 of the following conditions applies:
  • Is NOT a woman of childbearing potential (WOCBP) or Due to lenalidomide being a thalidomide analogue with risk for embryofetal toxicity and prescribed under a pregnancy prevention/controlled distribution program, and bortezomib having the potential to cause fetal harm, WOCBP participants will be eligible if they commit to either: abstain continuously from heterosexual sexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent OR to use birth control as follows: Two methods of reliable birth control (one method that is highly effective and one additional effective (barrier) method), beginning 4 weeks prior to initiating treatment with lenalidomide, during therapy, during dose interruptions and continuing for 4 weeks following discontinuation of lenalidomide treatment. Thereafter, WOCBP participants must use one method of reliable birth control that is highly effective for a further 3 months following discontinuation of belantamab mafodotin, or a further 6 months following discontinuation of bortezomib, whichever is longer. WOCBP must also agree not to donate eggs (ova, oocytes) for the purpose of reproduction during treatment, during dose interruptions and for 28-days following the last dose of lenalidomide, 4 months following discontinuation of belantamab mafodotin treatment or 7-months following the last dose of bortezomib, whichever is longer.

The participant should not receive lenalidomide until the investigator has verified that the results of these pregnancy tests are negative. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study intervention. The Investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.
