A Study of Isatuximab-based Therapy in Participants With Lymphoma

Summary

Primary Objectives: Phase 1 -To characterize the safety and tolerability of isatuximab in combination with cemiplimab in participants with relapsed and refractory classic Hodgkin's lymphoma (cHL), diffuse large B-cell lymphoma (DLBCL) or peripheral T-cell lymphoma (PTCL), and to confirm the recommended Phase 2 dose (RP2D). Phase 2 * Cohort A1 (anti-programmed cell death protein 1/ligand 1 \[PD-1/PD-L1\] naïve cHL): To assess the complete remission (CR) rate of isatuximab in combination with cemiplimab. * Cohort A2 (cHL progressing from PD-1/PD-L1), B (DLBCL) and C (PTCL): To assess the objective response rate (ORR) of isatuximab in combination with cemiplimab. Secondary Objectives: * To evaluate the safety of the RP2D of the combination of isatuximab with cemiplimab. * To evaluate the safety of the combination of isatuximab with cemiplimab and radiotherapy in participants with cHL. * To evaluate the immunogenicity of isatuximab and cemiplimab when given in combination. * To characterize the pharmacokinetic (PK) profile of isatuximab and cemiplimab when given in combination. * To assess overall efficacy of isatuximab in combination with cemiplimab and isatuximab in combination with cemiplimab and radiotherapy.
