Frequently asked questions about SAR408701

What is SAR408701?

SAR408701 is an investigational small molecule developed by Sanofi for the treatment of advanced malignant solid tumors. It is being studied in oncology and is designed to target CEACAM5, a protein expressed on certain tumor cells. It has been evaluated in a Phase 1 clinical trial in Japanese patients with advanced malignant solid tumors.

What does SAR408701 target?

SAR408701 targets CEACAM5, a protein that is expressed on the surface of certain cancer cells. By binding to CEACAM5, the drug is designed to act against CEACAM5-expressing malignant solid tumors. The Phase 1 study of SAR408701 enrolled patients whose tumors were selected based on this biomarker.

Who is developing SAR408701?

SAR408701 is being developed by Sanofi, which trades under the ticker SNY. Sanofi is the sponsor of the clinical program evaluating SAR408701 in advanced malignant solid tumors. The drug is an investigational small molecule in the oncology therapeutic area.

What phase is SAR408701 in?

SAR408701 is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA. The Phase 1 trial evaluating SAR408701 in Japanese patients with advanced malignant solid tumors has been completed, and no active trials are currently listed for this asset.

What clinical trials is SAR408701 in?

SAR408701 has been evaluated in one completed Phase 1 clinical trial, NCT03324113, titled Evaluation of SAR408701 in Japanese Patients With Advanced Malignant Solid Tumors. The trial enrolled 34 patients in Japan, included both sexes, and required a minimum age of 20 years. It was an uncontrolled study.

What is SAR408701 used for?

SAR408701 is being studied for the treatment of advanced malignant solid tumors, also described as malignant neoplasms. The Phase 1 trial NCT03324113 evaluated SAR408701 in Japanese patients with advanced malignant solid tumors. It is an investigational therapy and is not approved for any indication.
