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

Condition(s) studied

Investigational drug(s) / intervention(s)

Talquetamab: Talquetamab will be administered by subcutaneous (SC) injection.

Teclistamab: Teclistamab will be administered by SC injection.

Study 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).

Eligibility

Primary outcome measure(s)

• Part 1: Number of Participants with Dose Limiting Toxicity (DLT) — Approximately 5 years 10 months
  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 1: Severity of DLT as Assessed by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) — Approximately 5 years 10 months
  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 2: Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) as a Measure of Safety and Tolerability — Approximately 5 years 10 months
  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 Severity — Approximately 5 years 10 months
  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 3: Overall Response Rate (ORR) — Approximately 5 years 10 months
  ORR is defined as the percentage of participants who have a partial response (PR) or better according Independent Review Committees (IRC).
