A Study of Investigational SAR256212 in Combination With SAR245408 in Patients With Solid Tumor Cancers

Study Overview
=================
Brief Summary
-----------------
Primary Objective: To determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of SAR245408 administered in combination with SAR256212 in adult patients with locally advanced or metastatic solid tumors. Secondary Objectives: To characterize the global safety profile of SAR245408 in combination with SAR256212 To evaluate the pharmacokinetic (PK) profile of SAR245408 and SAR256212 used in combination To evaluate the objective response rate (ORR) and tumor volume change (for expansion cohort only) To determine the immunogenicity of SAR256212 as administered with SAR245408

Detailed Description
-----------------
There is a 28 day screening period followed by 28 day cycles (21 day cycle for the every three week dosing regimen, if used) . Patients will continue to receive SAR245408/SAR256212 as long as there is clinical benefit or until a study withdrawal criterion is met. The last posttreatment visit will be 60 days after the last dose or until IMP-related toxicities have resolved or are deemed irreversible, whichever is later.
