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

Phase 1
Active, not recruiting
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.

Inclusion Criteria
  • Have documented initial diagnosis of multiple myeloma according to International Myeloma Working Group (IMWG) diagnostic criteria
  • Participants with relapsed or refractory disease that are not a candidate for available therapy with established clinical benefit
  • Have measurable disease at screening as defined by at least 1 of the following: a) Serum M-protein level greater than or equal to (>=) 0.5 grams per deciliter (g/dL); b) Urine M-protein level >= 200 milligrams (mg) per 24 hours; c) Light chain multiple myeloma: Serum immunoglobulin (Ig) free light chain (FLC) >= 10 milligrams/deciliter (mg/dL) and abnormal serum Ig kappa lambda FLC ratio
  • Have an Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1
Exclusion Criteria
  • Prior antitumor therapy within 21 days prior to the first dose of study treatment (proteasome inhibitor [PI] therapy or radiotherapy within 14 days, immunomodulatory drug (IMiD) agent therapy within 7 days, gene -modified adoptive cell therapy or autologous stem cell transplant within 3 months)
  • Prior therapy with PD-1 inhibitors, allogeneic stem cell transplant or solid organ transplant

  • Active Central Nervous System (CNS) involvement or exhibition of clinical signs of meningeal involvement of multiple myeloma. If either is suspected, brain magnetic resonance imaging (MRI) and lumbar cytology are required
  • Live, attenuated vaccine within 4 weeks before the first dose of study treatment
  • Non-hematologic toxicity from prior anticancer therapy that has not resolved to baseline levels or to Grade less than or equal to (<=) 1 (except alopecia [any grade] or peripheral neuropathy to Grade <= 2)
  • Received a cumulative dose of corticosteroids equivalent to >= 140 milligrams (mg) of prednisone within the 14-day period before the start of study treatment administration

Primary Outcome Measures
NameTimeMethod
Number of Participants with Abnormalities in Clinical Laboratory AssessmentsUp 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 SeverityUp 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.
