About Gradalis, Inc.
Gradalis is a clinical-stage biotechnology company advancing Vigil®, a Phase 3–ready, personalized immunotherapy built on its proprietary bi-shRNA platform. Vigil harnesses the patient’s own tumor clonal neoantigens - without requiring new targets for each indication - to activate the immune system and deliver durable antitumor responses. In the Phase 2 VITAL trial, Vigil demonstrated a statistically significant and clinically meaningful overall survival benefit in ovarian cancer patients who are homologous recombination proficient (HRP, which includes BRCA wild type) and have high clonal tumor mutation burden (cTMB-H). The FDA granted Regenerative Medicine Advanced Therapy (RMAT) designation to Vigil on the basis of these results. HRP status occurs in many solid tumor indications, and combined with cTMB, enables Gradalis to identify the right patients for its therapy. Early clinical experience has shown signs of efficacy across several different solid tumors of high unmet need, underscoring Vigil’s potential for broad use and long-term value creation.
