Official title

A Phase 1/1b First-in-human Dose Escalation and Expansion Study for the Evaluation of Safety, Pharmacokinetics, Pharmacodynamics, and Anti-tumor Activity of SAR439459 Administered Intravenously as Monotherapy and in Combination With Cemiplimab in Adult Patients With Advanced Solid Tumors

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Primary Objectives: Dose escalation (Part 1) Part 1A (SAR439459 monotherapy) * To determine the maximum tolerated dose (MTD) and/or maximum administered dose (MAD) of SAR439459 when administered intravenously as monotherapy in adult patients with advanced solid tumors. Part 1B (SAR439459 and cemiplimab combination therapy) * To determine the MTD and/or MAD of SAR439459 administered intravenously in combination with cemiplimab administered intravenously in adult patients with advanced solid tumors. Dose expansion (Part 2) Part 2A (SAR439459 monotherapy) * To determine optimal dose of SAR439459 administered intravenously in adult patients with advanced melanoma who have failed a prior therapy based on anti-PD-1 (programmed cell death-1) or anti-PD-L1. Part 2B (SAR439459 and cemiplimab combination therapy) * To determine the objective response rate (ORR) of SAR439459 in combination with cemiplimab in adult patients with selected advanced solid tumors by evaluation of antitumor response according to Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1). Secondary Objectives: * Pharmacokinetic (PK) profile SAR439459 monotherapy and combined with cemiplimab, PK profile of cemiplimab combined with SAR439459. * Immunogenicity of SAR439459 monotherapy and combined with cemiplimab. Dose escalation (Part 1) * Overall safety/tolerability profile of SAR439459 monotherapy and combined with cemiplimab. * Preliminary recommended phase 2 dose (pRP2D) of SAR439459 as monotherapy or combined with cemiplimab. Dose expansion (Part 2) * Progression free survival (PFS), time to progression (TTP), ORR, and safety of SAR439459 as monotherapy and PFS, TTP, duration of response (DOR), disease control rate (DCR) and safety in combination with cemiplimab. * To confirm the optimal dose of SAR439459 administered in combination with cemiplimab.
