A First-in-human, Open-label, Phase 1 Study to Evaluate the Safety, Antitumor Activity, Pharmacokinetics, and Pharmacodynamics of Subcutaneous SAR446523, an Anti-GPRC5D ADCC-enhanced Monoclonal Antibody, in Participants With Relapsed/Refractory Multiple Myeloma
Sanofi
Summary
This is a first-in-human study of SAR446523 conducted in patients with RRMM. The study consists of two parts: Dose escalation (Part A): In this part, up to several dose levels (DLs) of SAR446523 will be explored to determine the maximum administered dose (MAD), maximum tolerated dose (MTD), and recommended dose range (RDR) of 2 dose regimens which will be tested in the dose optimization part. Dose optimization (Part B): In this part, participants will be randomly assigned in a 1:1 ratio using interactive response technology (IRT) to either one of the chosen dose regimens of SAR446523 (determined from data coming from Part A), to determine the optimal dose as the recommended phase 2 dose (RP2D) of SAR446523.
Description
The study will be considered ongoing until the last participant last visit has occurred. Participants will be allowed to continue therapy until disease progression, unacceptable AEs, participant or Investigator's request to discontinue treatment.
