A Study of Talquetamab in Participants With Relapsed or Refractory Multiple Myeloma

Study Purpose

The purpose of this study is to evaluate the efficacy and safety of talquetamab in participants with relapsed or refractory multiple myeloma at the recommended Phase 2 dose(s) (RP2Ds) (Part 3).

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over
Gender	All

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT04634552
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 2

Additional Details

Multiple myeloma is a malignant plasma cell disorder characterized by osteolytic lesions, increased susceptibility to infections, hypercalcemia, and renal failure. Talquetamab is a humanized immunoglobulin G4 proline, alanine, alanine (IgG4PAA) bispecific antibody designed to target G protein-coupled receptor family C group 5-member D (GPRC5D) and the CD3 molecule found on T lymphocytes (T cell). 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 (30 days (+ 7 days)] visit); and a post-treatment follow-up phase (until the end of study unless the participant has died, is lost to follow up or has withdrawn consent). Total duration of study is up to 2 years (after the last participant receives their first dose). Safety, pharmacokinetics (PK), laboratory tests, and questionnaire will be assessed at specified time points during this study. Participants safety and study conduct will be monitored throughout the study. The corresponding study (NCT03399799) is the Phase 1 part of the study and TALMMY1001- Part 3 is the Phase 2 part of the study.

Arms & Interventions

Arms

Experimental: Part 3: Cohort A (Talquetamab)

Cohort A will enroll participants with multiple myeloma who have previously received greater than or equal to (>=) 3 prior lines of therapy and have not been exposed to T cell redirection therapies. Participants will receive talquetamab subcutaneously (SC) at a recommended Phase 2 dose (RP2D) selected after review of safety, efficacy, PK, and pharmacodynamic data from Part 1 and Part 2 of this study.

Experimental: Part 3: Cohort B (Talquetamab)

Cohort B will enroll participants with multiple myeloma who have previously received >= 3 prior lines of therapy and have been exposed to T cell redirection therapies. Participants will receive talquetamab subcutaneously (SC) at a recommended Phase 2 dose (RP2D) selected after review of safety, efficacy, PK, and pharmacodynamic data from Part 1 and Part 2 of this study.

Experimental: Part 3: Cohort C (Talquetamab)

Cohort C will enroll participants with multiple myeloma who have previously received >= 3 prior lines of therapy and have not been exposed to T cell redirection therapies. Participants will receive talquetamab SC biweekly at a RP2D selected after review of safety, efficacy, PK, and pharmacodynamic data from Part 1 and Part 2 of this study.

Experimental: Part 3: Cohort D (Talquetamab)

Cohort D will enroll participants with multiple myeloma who have previously received >= 3 prior lines of therapy. Participants will receive talquetamab SC biweekly at a RP2D selected after review of safety, efficacy, PK, and pharmacodynamic data from Part 1 and Part 2 of this study.

Interventions

Drug: - Talquetamab

Talquetamab will be administered SC until disease progression.
