A Study of the Combination of Talquetamab and Teclistamab in Participants With Relapsed or Refractory Multiple Myeloma
Sponsor: Janssen Research & Development, LLC
ClinicalTrials ID:NCT04586426
This study evaluates talquetamab and teclistamab in relapsed/refractory multiple myeloma. It includes screening, treatment, and follow-up phases over 5 years. Participants must have a documented diagnosis and meet specific criteria. Exclusions include recent targeted therapies and certain conditions. Interventions are administered subcutaneously.

Program Overview
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).
Description
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 follow-up phase (after end of treatment and up to 16 weeks after last dose of study drug(s) for each participant). End of study is defined as 2 years after the last participant has received his or her initial dose of the treatment combination. Total duration of study is Approximately 5 years. Efficacy, safety, pharmacokinetics (PK), immunogenicity, and biomarkers will be assessed at specified time points during this study. Participants safety and study conduct will be monitored throughout the study.
Eligibility Criteria
Inclusion Criteria
- Documented initial diagnosis of multiple myeloma according to International Myeloma Working Group (IMWG) diagnostic criteria
- Part 1 and 2: Participant could not tolerate or has disease that is relapsed or refractory to established therapies, including the last line of therapy. Part 3: (a) Relapsed or refractory disease, and exposed to a PI, IMiD, and an anti-CD38 mAb; (b) Documented evidence of progressive disease based on investigator's determination of response by IMWG criteria on or after their last regimen
- Part 1 and Part 2: Eastern Cooperative Oncology Group (ECOG) performance status grade of 0 or 1 at screening and immediately before the start of study drug administration. Part 3: ECOG performance status grade of 0, 1, or 2 at screening and immediately before the start of study drug administration
Exclusion Criteria
