BOSTON, MA, USA I October 23, 2023 I Sensei Biotherapeutics, Inc. (Nasdaq: SNSE), a clinical stage immuno-oncology company focused on the discovery and development of next-generation therapeutics for cancer patients, today presented a trial-in-progress poster from the Phase 1/2 clinical trial for SNS-101, a conditionally active, human monoclonal antibody targeting the immune checkpoint VISTA (V-domain Ig suppressor of T cell activation), at the European Society for Medical Oncology Congress (ESMO) 2023.

The multi-center Phase 1/2 clinical trial is a first-in-human, open-label, dose escalation study evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of SNS-101 as both a monotherapy and in combination with Regeneron’s PD-1 inhibitor Libtayo® in patients with advanced solid tumors. To date, four patient cohorts have been enrolled in the monotherapy arm. Sensei expects to report initial pharmacokinetic and safety monotherapy data in the fourth quarter of 2023, and topline monotherapy data in 2024. The company has also initiated the combination arm of the study and expects to report initial combination safety and pharmacokinetic data in the first quarter of 2024, with preliminary anti-tumor activity combination data in 2024.

The full poster is available for viewing on Sensei’s website in the “Events & Presentations” section of the Company’s Investor Relations website at www.senseibio.com.

About Sensei Biotherapeutics:
Sensei Biotherapeutics (Nasdaq: SNSE) is a clinical stage immuno-oncology company focused on the discovery and development of next-generation therapeutics for cancer patients. Through its TMAb™ (Tumor Microenvironment Activated biologics) platform, Sensei develops conditionally active therapeutics designed to disable immunosuppressive signals or activate immunostimulatory signals selectively in the tumor microenvironment to unleash T cells against tumors. Sensei’s lead investigational candidate is SNS-101, a conditionally active antibody designed to block the V-domain Ig suppressor of T cell activation (VISTA) checkpoint selectively within the low pH tumor microenvironment, where VISTA acts as a suppressor of T cells by binding the receptor PSGL-1. The company is also developing SNS-102, a conditional binding monoclonal antibody targeting V-Set and Immunoglobulin Domain Containing 4 (VSIG-4), as well as SNS-103, also a conditionally active monoclonal antibody targeting ecto-nucleoside triphosphate diphosphohydrolase-1 (ENTPDase1), also known as CD39.  For more information, please visit www.senseibio.com, and follow the company on Twitter @SenseiBio and LinkedIn
