A Dose Escalation and Expansion Study of ABBV-383 in Combination With Anti-Cancer Regimens for the Treatment of Patients With Relapsed/Refractory Multiple Myeloma

Description

Multiple myeloma (MM) is a plasma cell disease characterized by the growth of clonal plasma cells in the bone marrow. The purpose of this study is to assess the safety and toxicity of ABBV-383 when co-administered with pomalidomide-dexamethasone (Pd), lenalidomide-dexamethasone (Rd), daratumumab-dexamethasone (Dd), or nirogacestat (Niro) in adult participants with relapsed/refractory (R/R) multiple myeloma (MM). Adverse events and change in disease activity will be assessed. ABBV-383 is an investigational drug being developed for the treatment of R/R MM. Study doctors put the participants in groups called treatment arms. ABBV-383 co-administered with Pd, Rd, Dd, or Niro will be explored. Each treatment arm receives a different treatment combination depending on stage of the study and eligibility. This study will include a dose escalation phase to determine the best dose of ABBV-383, followed by a dose expansion phase to confirm the dose. Approximately 270 adult participants with R/R M

Trial Eligibility

Inclusion Criteria: * Eastern Cooperative Oncology Group (ECOG) performance of \<= 2. * Must have confirmed diagnosis of Relapsed/Refractory (R/R) Multiple Myeloma (MM) with documented evidence of progression during or after the participant's last treatment regimen based on the investigator's determination of the International Myeloma Working Group (IMWG) criteria. * Must have measurable disease as outlined in the protocol. * Must be naïve to treatment with ABBV-383 and must have never received BCMA-targeted therapy.
