Study Groups

A - Isatuximab/CellProtect

Isatuximab will be given intravenously (IV) at the dose of 10 mg/kg on Days 1, 8, 15, 22 (cycle 1), 36, 50 (cycle 2), 64, 78 (cycle 3) and monthly thereafter (cycles 4-36).

CellProtect will be given IV infusion at the dose of 3x10^7 cells/kg day 29 , 43 and 3-10x10^7 on day 57.

Each cycle will be 28 days, after completion of third cycles, patients will continue with Isatuximab alone until disease progression, unacceptable AE, death, completion of 3 years of treatment or patient's decision to discontinue, whichever occurs first.

Group Type: EXPERIMENTAL

CellProtect

Intervention Type: DRUG

In vitro expanded and activated autologous NK cells

Isatuximab

Intervention Type: DRUG

Naked immunoglobulin (Ig) G1 monoclonal antibody (mAb) that selectively binds to the human cell surface antigen molecule classified as cluster of differentiation (CD) 38

B - Isatuximab

Isatuximab will be given intravenously (IV) at the dose of 10 mg/kg on Days 1, 8, 15, 22 (cycle 1), 36, 50 (cycle 2), 64, 78 (cycle 3) and monthly thereafter (cycles 4-36).

Each cycle will be 28 days, after completion of third cycles, patients will continue with Isatuximab alone until disease progression, unacceptable AE, death, completion of 3 years of treatment or patient's decision to discontinue, whichever occurs first.

E4. Diagnosis of Waldenström's disease, or other conditions in which IgM M-protein is present in the absence of a clonal plasma cell infiltration with lytic bone lesions.

E5. Prior or current systemic therapy, or SCT for symptomatic multiple myeloma, with the exception of an emergency use of a short course (equivalent of dexamethasone 40 mg/day for 4 days) of corticosteroids, if completed within 14 days prior to randomization.
