A Study to Investigate the Safety and Efficacy of SAR446523 Injected Subcutaneously in Adult Participants With Relapsed/Refractory Myeloma
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 (deter
