A Study of the Combination of Talquetamab and Teclistamab in Participants With Relapsed or Refractory Multiple Myeloma

Phase 1
Active, not recruiting
Conditions
Multiple Myeloma
Interventions
Registration Number
NCT04586426
Lead Sponsor
Janssen Research & Development, LLC
Brief Summary

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).

Detailed 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.

Primary Outcome Measures
NameTimeMethod
Part 1: Severity of DLT as Assessed by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE)Approximately 5 years

Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening, and Grade 5= Death related to adverse event.

Part 1: Number of Participants with Dose Limiting Toxicity (DLT)Approximately 5 years

The dose limiting toxicities are based on drug related adverse events and defined as any of the following events: hematological or non-hematological toxicity of grade 3 or higher.

Part 2: Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) as a Measure of Safety and TolerabilityApproximately 5 years

An AE is any untoward medical occurrence in a clinical study participant administered a medicinal (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. SAE is any AE that results in: death, persistent or significant disability/incapacity, requires inpatient hospitalization or prolongation of existing hospitalization, is life-threatening experience, is a congenital anomaly/birth defect, and suspects transmission of any infectious agent via a medicinal product, is medically important.

Part 2: Number of Participants with Adverse Events and SAEs by SeverityApproximately 5 years

Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0.
