Calidi Biotherapeutics Inc. announced new data on its lead therapeutic candidate, CLD-401, at the 2025 Society of Immunotherapy for Cancer $(SITC)$ Annual Meeting. CLD-401, developed using Calidi's RedTail platform, is a tumor-tropic oncolytic virus designed for systemic administration that selectively replicates in tumor cells, induces immune priming at the tumor site, and expresses high levels of IL-15 superagonist in the tumor microenvironment. According to the company, preclinical syngeneic models demonstrated targeted delivery and expression of IL-15 superagonist in tumors with minimal systemic exposure. The latest results were presented at SITC 2025. Calidi is currently conducting IND-enabling studies for CLD-401 and anticipates submitting an Investigational New Drug (IND) application by the end of 2026.
