Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

* Total bilirubin >1.5 × upper limit of normal (ULN) (unless the subject has documented Gilbert syndrome in which case direct bilirubin should not be >2.5 × ULN).
* Aspartate aminotransferase (AST/SGOT) or Alanine aminotransferase (ALT/SGPT) >2.5 × ULN.
* Participants with Grade 3 or 4 hypercalcemia (corrected serum calcium of >12.5 mg/dL; >3.1 mmol/L; ionized calcium >1.6 mmol/L; or requiring hospitalization) will not be eligible unless participants recover to Grade 2 or less under anti-hypercalcemia treatment.

Summary
Brief 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 pRP2D and schedule for SAR445514 in RRMM (Part 3a) and RRLCA (Part 3b).

Approximately 111 participants will be enrolled and treated by study intervention and separated as such:

Part 1a: Approximately 30 to 40 participants Part 1b: Approximately 6 to 12 participants Part 2: Approximately 30 participants Part 3a: Approximately 15 participants Part 3b: Approximately 14 participants
