Sensei Biotherapeutics Announces Clinical Trial Collaboration Agreement with AstraZeneca for Two Phase 2 Studies of SNS-301

Sensei Biotherapeutics, Inc., a clinical-stage biopharmaceutical company developing precision immuno-oncology therapies, announced a clinical trial collaboration with AstraZeneca to evaluate the safety, tolerability and preliminary activity of AstraZeneca’s IMFINZI (durvalumab), a human monoclonal antibody directed against programmed death-ligand 1 (PD-L1), in combination with SNS-301. SNS-301, Sensei’s first-in-class immunotherapy candidate, is a therapeutic cancer vaccine utilizing a bacteriophage viral vector targeting aspartate β-hydroxylase (ASPH), a novel embryonic antigen.

Under the terms of the agreement, AstraZeneca and Sensei will collaborate to evaluate the combination of SNS-301 and IMFINZI® in patients with locally advanced head and neck cancer in the neoadjuvant setting in conjunction with TPF chemotherapy prior to surgical resection and in ASPH+ patients with various locally advanced unresectable or metastatic/recurrent solid tumors. AstraZeneca will supply IMFINZI for these clinical studies and Sensei will sponsor and fund the Phase 2 studies. AstraZeneca and Sensei will each retain full worldwide rights to their respective molecules.

“We are extremely pleased to collaborate with AstraZeneca, a leader in the cancer immunotherapy field. SNS-301 targets a novel mechanism to activate and direct ASPH-specific T-cells to tumors. We believe that when combined with IMFINZI, SNS-301 has the potential to deepen and broaden the overall immune-mediated response,” said John Celebi, President and Chief Executive Officer of Sensei Biotherapeutics. “This clinical collaboration strengthens our position as pioneers of precision oncology therapeutics by focusing on improved clinical outcomes for ASPH-positive patients through novel clinical combinations.”
