Safety, Preliminary Efficacy and PK of Isatuximab (SAR650984) Alone or in Combination With Atezolizumab in Patients With Advanced Malignancies

Primary Objectives:

  • Phase1: To characterize the safety and tolerability of isatuximab in combination with atezolizumab in participants with unresectable hepatocellular carcinoma (HCC), platinum-refractory recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN), platinum-resistant/refractory epithelial ovarian cancer (EOC), or recurrent glioblastoma multiforme (GBM), and to determine the recommended Phase 2 dose (RP2D).
  • Phase2: To assess response rate (RR) of isatuximab in combination with atezolizumab in participants with HCC or SCCHN or EOC.
  • Phase2: To assess the progression free survival rate at 6 months (PFS-6) of isatuximab in combination with atezolizumab, or as a single agent in participants with GBM.

Secondary Objectives:

  • To evaluate the safety profile of isatuximab monotherapy (GBM only), or in combination with atezolizumab in Phase 2.
  • To evaluate the immunogenicity of isatuximab and atezolizumab.
  • To characterize the pharmacokinetic (PK) profile of isatuximab single agent (GBM only) and atezolizumab in combination with isatuximab.
  • To assess the overall efficacy of isatuximab in combination with atezolizumab, or single agent (GBM only).
