Estudo de Belantamab Mafodotin Plus Standard of Care (SoC) em Mieloma Múltiplo Recentemente Diagnosticado (DREAMM 9)

6 de novembro de 2026 atualizado por: GlaxoSmithKline

Um estudo de avaliação de fase 1, randomizado, de dose e esquema para investigar a segurança, farmacocinética, farmacodinâmica e atividade clínica de Belantamab Mafodotin administrado em combinação com tratamento padrão em participantes com mieloma múltiplo recém-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.
