Dose Escalation and Expansion Study of SAR443216 in Participants With Relapsed/Refractory HER2 Expressing Solid Tumors

Stopped early · Phase 1

Conditions studied: Neoplasm Malignant, Breast Cancer, Lung Neoplasm Malignant, Gastric Cancer, Neoplasm

In brief

Primary Objectives: Part 1 (Dose Escalation) * To determine the MTD/maximum administered dose (MAD) of SAR443216 administered as a single agent in participants with HER2 expressing solid tumors and determine the RD(s) for intravenous (IV) and subcutaneous (SC) administration in the dose escalation part. * To determine the safety of SAR443216 after intravenous (IV) and subcutaneous (SC) administration. Part 2 (Dose expansion) • To assess preliminary clinical activity of single agent SAR443216 at the RD(s) in participants with HER2 expressing solid tumors, with various levels of HER2 expression. Secondary Objectives: Part 1 • To assess preliminary clinical activity of single agent SAR443216 after IV and SC administration at the RD(s) in participants with HER2 expressing solid tumors, with various levels of HER2 expression. Part 2 • To determine the safety of SAR443216. Part 1 and 2 * To characterize the pharmacokinetic (PK) profile of SAR443216 when administered as a single agent after IV and SC (Part 1 only) administration. * To evaluate the immunogenicity of SAR443216 after IV and SC administration. * To assess preliminary clinical activity of single agent SAR443216 at the RD(s) in participants with HER2 expressing solid tumors, with various levels of HER2 expression.
