Estudio de Belantamab Mafodotin Plus Standard of Care (SoC) en mieloma múltiple recién diagnosticado (DREAMM 9)

6 de noviembre de 2026 actualizado por: GlaxoSmithKline

Estudio de fase 1, aleatorizado, de evaluación de la dosis y el programa para investigar la seguridad, la farmacocinética, la farmacodinámica y la actividad clínica de belantamab mafodotin administrado en combinación con el tratamiento estándar en participantes con mieloma múltiple recién diagnosticado

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.

Blood Samples were collected for Pharmacokinetic analysis of belantamab mafodotin. The last PK assessment used to derive AUC0-504h was intended to be collected approximately 504 hours (21 days) after the start of the first infusion. Depending on the dosing schedule, this assessment occurred either at the Day 22 visit (±3 days) for participants in the Q6/8W and Q9/12W cohorts or at the Cycle 2 Day 1 pre-dose visit for participants in the Q3W cohorts. Therefore, samples collected at Day 22 or Cycle 2 Day 1 predose represent the protocol-defined PK assessment performed at approximately 504 hours after Dose 1.
