A Phase 2 Study of Isatuximab in Combination With Bortezomib, Cyclophosphamide and Dexamethasone Followed by Isatuximab and Lenalidomide Maintenance in Newly Diagnosed Patients With Multiple Myeloma and Severe Renal Impairment

This is an Investigator-Initiated, phase 2, prospective, open-label study designed to be conducted in six hospitals in Greece. Eligible patients will initially receive an induction phase of six 28-day cycles of isatuximab in combination with bortezomib, cyclophosphamide, and dexamethasone (VCd), followed by a maintenance phase with isatuximab and lenalidomide until disease progression, death, unacceptable adverse events, lost to follow up, or consent withdrawal, whichever occurs first. The study will last for approximately 36 months (follow-up period), starting from the date of the first patient in, to the date of the last patient last visit. The primary objective is to assess the effect of induction treatment with isatuximab in combination with VCd on the renal function of newly diagnosed patients with multiple myeloma and severe renal impairment (RI). The secondary objectives are to evaluate the effect of isatuximab in combination with VCd, followed by lenalidomide maintenance on: Overall response rate, Progression-Free Survival, Time to Response, Duration of Response, Overall Survival, Minimal Residual Disease negativity rate, Safety
