About
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
Full description
The duration of the study for a participant will include A screening period: up to 28 days prior day 1 of cycle 1 (C1D1) A treatment period: enrolled participants will receive administration of 4 weeks cycles of SAR445514 subcutaneously.
The End of treatment visit will occur 30 days (+/- 7 days) from last investigational medicinal product (IMP) administration or prior initiation of further therapy, whichever comes first.
The follow-up period will continue until death, participant's request to discontinue study, final Overall Survival analysis or upon cancellation of survival follow-up at the discretion of the Sponsor at any timepoint.

Inclusion criteria
Participants must have a documented diagnosis of multiple myeloma (Part 1a, 2, and 3a) or light chain amyloidosis (Part 1b and 3b).
Participants with RRMM (Part 1, 2, and 3a)
- Participants with measurable disease for RRMM
- Participants with MM must have received at least 2 prior lines of therapy which must include at least 2 consecutive cycles of a second or third generation immunomodulator, steroid, proteasome inhibitor and anti-CD38 monoclonal antibody (MoAb).
- Participants must have documented evidence of progressive disease (PD), as per IMWG 2016 criteria.
Participants with RR LCA (Part 1b and 3b) must have received at least 1 prior line of treatment comprising at least 1 proteasome inhibitor.
- Participants with measurable disease according to ISA 2012.
- Participants must have documented evidence of progressive disease (PD), as per ISA 2012 criteria.
- One or more organ impacted by amyloidosis as per National comprehensive cancer network (NCCN) guidelines.
For dose escalation, body weight within 40 to 120 kg

Exclusion criteria
Participants are excluded from the study if any of the following criteria apply:
Medical conditions
- Primary refractory MM defined as participants who never achieved at least a minimal response with any treatment during the disease course
- Second primary malignancy
Participants with RRMM (Part 1a, 2, and 3a)
- For MM participants, primary systemic LCA and plasma cell leukemia
- For MM participants, congestive heart failure (New York Heart Association [NYHA]) Grade ≥II; cardiomyopathy, active ischemia, or any other uncontrolled cardiac condition
Participants with RR LCA (Part 1b and 3b)
-
For LCA participants, evidence of clinically significant cardiovascular condition, defined as one or more of the following:
- N-terminal prohormone of brain natriuretic peptide (NT-proBNP) >8500 ng/mL
- New York Heart Association (NYHA) classification III or IV heart failure
- Heart failure that, in the opinion of the Investigator, is not primarily related to LCA cardiomyopathy (including, but not limited to, ischemic heart disease, uncorrected valvular disease, infections)
- Prior event (history) in the last 6 months of acute coronary syndrome, myocardial infarction or unstable angina as well as participants who during the last 6 months experienced a percutaneous cardiac intervention with stent and/or a coronary artery bypass
- Hospitalization in the last 4 weeks prior to treatment related to a cardiovascular event
- Participants with prior history of arrhythmia and/or cardiac conduction disorders for which a pacemaker or an implantable cardioverter defibrillator (ICD) is required but has not been placed. This includes, but may not be limited to, sustained ventricular tachycardia, association of an atrioventricular, or sinoatrial nodal dysfunction
-
For LCA participants, a systolic blood pressure <100 mmHg or a diastolic blood pressure <55 mmHg.
-
For LCA participants: previous or current diagnosis of symptomatic MM, including the presence of lytic bone disease, plasmacytomas, ≥60% plasma cells in the BM, or hypercalcemia.
All participants
- Uncontrolled infection within 14 days prior to study treatment.
- Known acquired immunodeficiency syndrome-related illness or known human immunodeficiency virus (HIV) disease requiring antiviral treatment or active hepatitis A (defined as positive hepatitis A antigen or positive IgM); HIV serology at screening will be tested for participants in countries where it is required by local regulations.
- Uncontrolled or active hepatitis B virus (HBV) infection: participants with positive B surface antigen (HBsAg) and/or HBV deoxyribonucleic acid (DNA)
- Active hepatitis C virus (HCV) infection: positive HCV ribonucleic acid (RNA) and negative anti-HCV.
Prior/concomitant therapy
- Any anti-MM drug treatment within 14 days before study treatment
- Prior allogenic hematopoietic stem cell (HSC) transplant with active graft-versus-host disease (GvHD) (GvHD any grade and/or being under immunosuppressive treatment within the last 2 months prior to first IMP).
- Any major procedure within 14 days before the initiation of the study treatment
- Administration of an anti-CD38 monoclonal antibody (isatuximab or daratumumab) less than 90 days prior to the first administration of study treatment.
- Administration of an anti-BCMA agent (including, but not limited to, CAR T-cells, TCEs, antibody drug conjugate) less than 21 days prior to the administration of study treatment.
- Unresolved toxicities from prior anticancer therapy, defined as not having resolved to CTCAE Version 5.0 Grade 1, at the exception of residual Grade 2 peripheral neurotoxicity related to bortezomib and/or thalidomide and considered as stable.
- Participants with a contraindication to dexamethasone.
Prior/concurrent clinical study experience
