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withdrawn consent).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