Sentinel BioTherapeutics Launches with Novel IL-2 Immunotherapy Platform for Solid Tumors
- RBL LLC announced the launch of Sentinel BioTherapeutics, a clinical-stage company developing innovative immune-priming therapies for solid tumors that typically respond poorly to checkpoint inhibitors.
- The company's platform enables sustained local delivery of interleukin-2 (IL-2) through an allogeneic encapsulated cell-based system to enhance checkpoint inhibitor effectiveness against cancers like ovarian cancer and mesothelioma.
- Phase 1 clinical data presented at the 2025 ASCO Annual Meeting demonstrate dose-dependent increases in CTLA-4 expression on T cells, supporting the therapy's potential as a priming agent for checkpoint inhibition.
- Sentinel's lead program SENT001 holds fast-track designation for PROC and orphan disease designation for mesothelioma, with plans to initiate immune priming clinical trials for peritoneal solid tumors.
