Gradalis, Inc. is a late-stage biotechnology company based in Carrollton, Texas, focused on immunotherapies for cancer. Its lead program, Vigil, is a cellular immunotherapy that uses a patient’s tumor antigens to guide the immune system in recognizing and attacking cancer cells, and has shown positive survival signals in prior studies of solid tumors. The company’s proprietary bi-shRNA platform underpins Vigil and aims to modulate immune pathways to enhance anti-tumor responses across multiple cancer types. Gradalis is advancing a Phase 3 registration study in ovarian cancer, signaling progression toward potential approval for a key indication. In January 2026, the company appointed Steven D. Weinstein as chief executive officer, reflecting leadership change as it pursues late-stage development.
