A Study to Investigate Safety and Efficacy With SAR445514 in Participants With Relapsed/Refractory Multiple Myeloma (RRMM) and Relapsed/Refractory Light-chain Amyloidosis (RRLCA)

• Status: Not yet recruiting
• Trial end date: 2027-03-08

Summary

This is a first-in-human (FIH) Phase 1/Phase 2 study for evaluating SAR445514 in monotherapy in participants with relapsed/refractory multiple myeloma (RRMM) and relapsed/refractory light chain amyloidosis (RRLCA).

The study will comprise 3 parts:

A dose escalation phase (Part 1) in RRMM participants (Part 1a) that will evaluate several doses administered to determine 2 doses that will be tested in the dose optimization part.

A dose escalation will also be done in RRLCA participants (Part 1b) but started sequentially after the end of the dose escalation in RRMM participants. This dose escalation will evaluate the 2 doses planned to be used in dose optimization in RRMM, to ensure those doses are safe also for RRLCA participants.

A dose optimization phase (Part 2) that will be evaluating 2 doses determined from Part 1 to determine the preliminary recommended Phase 2 dose (pRP2D) and schedule for SAR445514 in RRMM.

A dose expansion phase (Part 3) that will evaluate the preliminary efficacy of the confirmed recommended Phase 2 dose (cRP2D) and schedule for SAR445514 in RRMM (Part 3a) and RRLCA (Part 3b).

Approximately 101 participants will be enrolled and treated by study intervention and separated as such:

Part 1a: Approximately 18 to 30 participants Part 1b: Approximately 6 to 12 participants Part 2: Approximately 30 participants Part 3a: Approximately 15 participants Part 3b: Approximately 14 participants

• Phase: Phase 1/Phase 2
