SAR650984 (Isatuximab), Lenalidomide, and Dexamethasone in Combination in RRMM Patients

Plasma Cell Myeloma Clinical Trial

Official title: A Phase 1b Study of SAR650984 (Anti-CD38 mAb) in Combination With Lenalidomide and Dexamethasone for the Treatment of Relapsed or Refractory Multiple Myeloma

Status Completed

Clinical Trial Summary

Primary Objectives: - To determine the maximum tolerated dose of SAR650984 (isatuximab) with lenalidomide and dexamethasone (LD) in patients with relapsed or refractory multiple myeloma. - Expansion Phase Only: To further evaluate preliminary evidence of antitumor activity (objective response rate [ORR]) of SAR650984 (isatuximab) in combination with LD using International Myeloma Working Group (IMWG) criteria. Secondary Objectives: - To evaluate the safety, including immunogenicity, of SAR650984 (isatuximab) in combination with LD in relapsed or refractory multiple myeloma. The severity, frequency and incidence of all toxicities will be assessed. - To evaluate the pharmacokinetics (PK) of SAR650984 (isatuximab) when administered in combination with LD and the PK of lenalidomide in combination with SAR650984 and dexamethasone. - To assess the relationship between clinical (adverse event [AE] and/or tumor response) effects and pharmacologic parameters (PK/pharmacodynamics), and/or biologic (correlative laboratory) results. - For the dose expansion phase, estimate the activity (ORR) using IMWG defined response criteria of SAR650984 (isatuximab) plus LD. - To describe progression-free survival (PFS) in patients treated with this combination.

Clinical Trial Description

The study duration for an individual patient will include a screening period for inclusion of up to 21 days, and at least 4 weeks of treatment in the absence of severe adverse reaction, dose limiting toxicity or disease progression plus up to 60 days post-treatment follow up. The treatment period may continue until disease progression, intolerable toxicity, or Investigator, sponsor, or patient decision to discontinue therapy. After study treatment discontinuation, an end of treatment (EOT) visit will be done at 30 days to assess safety, and at 30 and 60 days for anti-drug antibody (ADA) and PK. If the ADA is positive or inconclusive at day 60, then PK and ADA will be repeated every 30 days until ADA is negative. Patients who discontinue treatment for reasons other than progression of disease will be followed monthly until progression, initiation of subsequent therapy, or until the primary analysis cutoff date, whichever comes first. ;
