PHASE3

Isatuximab in Combination With Lenalidomide and Dexamethasone in High-risk Smoldering Multiple Myeloma

Sponsor: Sanofi

View on ClinicalTrials.gov

Summary

Primary Objectives: * Safety run-in Part: To confirm the recommended dose of isatuximab when combined with lenalidomide and dexamethasone in participants with high-risk smoldering multiple myeloma (SMM) * Randomized Phase 3 Part: To demonstrate the clinical benefit of isatuximab in combination with lenalidomide and dexamethasone in the prolongation of progression-free survival when compared to lenalidomide and dexamethasone in subjects with high-risk SMM Secondary Objectives: Safety run-in Part: * To assess overall response rate (ORR) * To assess duration of response (DOR) * To assess minimal residual disease (MRD) negativity in participants achieving very good partial response (VGPR) or complete response (CR) * To assess time to diagnostic (SLiM CRAB) progression or death * To assess time to first-line treatment for multiple myeloma (MM) * To assess the potential immunogenicity of isatuximab * Impact of abnormal chromosomal subtype on participant outcome Randomized Phase 3 Part: Key Secondary Objectives: To compare between the arms * MRD negativity * Sustained MRD negativity * Second progression-free survival (PFS2) * Overall survival Other Secondary Objectives: To evaluate in both arms * CR rate * ORR * DOR * Time to diagnostic (SLiM CRAB) progression * Time to biochemical progression * Time to first-line treatment for MM * Impact of abnormal chromosomal subtype on participant outcome * Safety and tolerability * Pharmacokinetics (PK) * Potential of isatuximab immunogenicity * Clinical outcome assessments (COAs)

Official title: A Phase 3 Randomized, Open-label, Multicenter Study of Isatuximab (SAR650984) in Combination With Lenalidomide and Dexamethasone Versus Lenalidomide and Dexamethasone in Patients With High-risk Smoldering Multiple Myeloma

Inclusion criteria: * Participants who are diagnosed within 5 years with SMM (per International Myeloma Working Group \[IMWG\] criteria), defined as serum M-protein ≥30 g/L or urinary M-protein ≥500 mg per 24 hour or both, and/or clonal bone marrow plasma cells (BMPCs) 10% to \<60%, and absence of myeloma defining events or other related conditions and with high-risk SMM * Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1 or 2 * Capable of giving voluntary written informed consent * Absolute neutrophil count (ANC) ≥1000/µL (1 × 10\^9/L) * Platelets ≥50,000/µL (50 × 10\^9/L) * Total bilirubin ≤3 mg/dL (except Gilbert syndrome, in which direct bilirubin should be -≤5 mg/dL). * Alanine aminotransferase ≤3× upper limit of normal (ULN), aspartate aminotransferase ≤ 3 × ULN. Exclusion criteria: * Evidence of any of the following calcium, renal failure, anemia, bone lesions (CRAB) criteria or Myeloma Defining Events (SLiM CRAB) detailed below (attributable to the participants SMM involvement): * Increased calcium levels: Corrected serum calcium \>1 mg/dL above the ULN or \>11 mg/dL * Renal insufficiency: Determined by glomerular filtration rate (GFR) \<40 mL/min/1.73 m² (Modification of Diet in Renal Disease \[MDRD\] Formula) or serum creatinine \>2 mg/dL * Anemia (hemoglobin 2 g/dL below lower limit of normal or \<10 g/dL or both) transfusion support or concurrent treatment with erythropoietin stimulating agents is not permitted * ≥ 1 bone lytic lesion * BMPCs ≥60% * Serum involved/uninvolved FLC ratio ≥100 and an involved FLC ≥100mg/L * Whole body magnetic resonance imaging (WB-MRI) or positron emission tomography-computed tomography (PET-CT) with more than 1 bone focal lesion (≥5 mm in diameter by MRI) * Primary systemic amyloid light-chain (AL) amyloidosis, monoclonal gammopathy of undetermined significance (MGUS), standard risk smoldering myeloma, soft tissue plasmacytoma, symptomatic myeloma * Uncontrolled infection within 28 days prior to randomization in Phase 3 or first study intervention administration in safety run-in * Clinically significant cardiac or vascular disease within 3 months prior to randomization, e.g. Myocardial Infarction; Unstable Angina; Coronary (e.g. Coronary Artery Bypass Graft, Percutaneous Coronary Intervention) or peripheral artery revascularization, Left Ventricular Ejection Fraction \<40%, Heart Failure NYHA III-IV, Stroke, Transient Ischemic Attack, Pulmonary Embolism, other thromboembolic event, cardiac arrhythmia (Grade 3 or higher by NCI-CTCAE Version 5.0) * Known acquired immunodeficiency syndrome (AIDS)-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).
