A Phase 1b/2 Dose Escalation and Expansion Study of the Combination of the Bispecific T Cell Redirection Antibodies Talquetamab and Teclistamab in Participants With Relapsed or Refractory Multiple Myeloma


Description

The purpose of this study is to identify the recommended Phase 2 regimen(s) (RP2R\[s\]) and schedule for the study treatment (Part 1), to characterize the safety of the RP2R(s) for the study treatment (Part 2) and to evaluate the anticancer activity of talquetamab + teclistamab in participants with relapsed or refractory multiple myeloma and extramedullary disease (EMD) (Part 3).Multiple myeloma is a malignant plasma cell disorder characterized by production of monoclonal proteins (M proteins), which are comprised of pathologic immunoglobulins (Ig) or fragments of such, which have subsequently lost their normal function. Rationale for combining talquetamab and teclistamab is the targeting of multiple proteins on the surface of multiple myeloma cells resulting in cell lysis. This study consists of 3 periods: screening phase (up to 28 days), treatment phase (start of study drug administration and continues until the completion of the end of treatment \[EOT\] visit); and a post-treatment
