A Study of Talquetamab and Teclistamab Each in Combination With a Programmed Cell Death Receptor-1 (PD-1) Inhibitor for the Treatment of Participants With Relapsed or Refractory Multiple Myeloma
- Conditions
- Relapsed/ Refractory Multiple Myeloma
- Interventions
- Registration Number
- NCT05338775
- Lead Sponsor
- Janssen Research & Development, LLC
- Brief Summary
The purpose of the study is to identify the safe dose(s) of a PD-1 inhibitor in combination with talquetamab or teclistamab, and to characterize the safety and tolerability of talquetamab or teclistamab when administered in combination with a PD-1 inhibitor.
- Detailed Description
Multiple myeloma is a malignant plasma cell disorder that accounts for approximately 10 percent (%) of all hematologic cancers, making it the second most common hematologic malignancy. The overall rationale of this study is that talquetamab or teclistamab in combination with a PD-1 inhibitor may lead to enhanced clinical responses in treatment of relapsed or refractory multiple myeloma through multiple mechanisms of action. The study will evaluate the clinical hypothesis that talquetamab or teclistamab can be safely administered at the selected dose when combined with a PD-1 inhibitor. The study will consist of a screening period, treatment period (Part 1: dose escalation and Part 2: dose expansion) and a post treatment follow-up. End of study is defined as last study assessment for last participant in study. Total duration of study is up to 2 years 5 months. Efficacy, safety, pharmacokinetics (PK), immunogenicity, and biomarkers will be assessed at specified time points.

Part 2: Dose Expansion Teclistamab Participants will receive either treatment regimen A or treatment regimen B with a PD-1 inhibitor at the dose levels identified in Part 1.
- Primary Outcome Measures
Name Time Method Number of Participants with Abnormalities in Clinical Laboratory Assessments Up to 2 years 5 months Number of participants with abnormalities in clinical laboratory assessments (serum chemistry and hematology) will be reported.
Number of Participants with Dose-Limiting Toxicity (DLTs) Up to 2 years 5 months The DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity.
Number of Participants with Adverse Events (AEs) Up to 2 years 5 months An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
Number of Participants with Adverse Events (AEs) by Severity Up to 2 years 5 months An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study. 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.
- Secondary Outcome Measures
