Primary Objectives: * Phase I: To evaluate safety and tolerability of isatuximab in Japanese participants with relapsed and refractory multiple myeloma. * Phase II: To evaluate efficacy of isatuximab at recommended dose and to further evaluate the overall response rate (ORR) of isatuximab in Japanese participants with relapsed and refractory multiple myeloma. Secondary Objectives: * To evaluate the safety including immunogenicity of isatuximab. The severity, frequency and incidence of all adverse events were assessed. * To evaluate the pharmacokinetic (PK) profile of isatuximab in the proposed dosing schedule. * To assess the efficacy using International Myeloma Working Group (IMWG) uniform response criteria. * To assess the relationship between Baseline cluster of differentiation 38 (CD38) receptor density on multiple myeloma cells and efficacy.

detailed Description
The study duration for an individual participant included a screening period for inclusion of up to 21 days, the treatment period consisting of 28-day cycles and a follow-up period. Treatment with isatuximab might continue until disease progression, unacceptable adverse event, or other reason for discontinuation.
