About SNSE
Sensei Biotherapeutics, Inc. (Nasdaq: SNSE) is a clinical-stage biotechnology company focused on the discovery and development of next-generation therapeutics for cancer patients. The Company's lead program is PIKTOR, an investigational multi-node inhibitor of the PI3K/AKT/mTOR pathway in development for endometrial and breast cancer. The Company is also completing a Phase I/II trial of solnerstotug, its V-domain Ig suppressor of T cell activation (VISTA) inhibitor, in patients with advanced solid tumors. Its TMAb platform is designed to enable highly selective targeting through conditional antibody activation of immune cells in the tumor microenvironment without on-target, off-tumor activity. Its programs include Solnerstotug (SNS-101), SNS-102, SNS-103, and SNS-201. Solnerstotug is a conditionally active, human monoclonal IgG1 antibody designed to block the VISTA checkpoint, which acts as a suppressor of T cells by binding the receptor PSGL-1.
