(NYSE American: CLDI) ("Calidi" or the "Company"), a biotechnology company pioneering the development of targeted genetic medicines, reported it will present new data at the American Association of Cancer Research (AACR) (Free AACR Whitepaper) annual meeting in San Diego, California from April 17-22, 2026. The Company will showcase new data on CLD-401, a systemically delivered oncolytic virus that is designed to express high levels of IL-15 superagonist ("IL-15 SA") only in the tumor microenvironment ("TME"), currently in IND-enabling studies.

CLD-401 is the lead candidate from the Company’s RedTail platform, a systemically delivered virotherapy platform designed to selectively target tumors, remodel the TME, and enable high-level expression of therapeutic genetic payloads directly within the tumor. CLD-401 is engineered to express high levels of IL-15 SA, a known T- and NK-cell activator, in the TME. Data at AACR (Free AACR Whitepaper) will detail the pattern of CLD-401 mediated-IL-15 SA expression and the subsequent immune changes in the TME, leading to a robust therapeutic response. The Company expects to file an IND for CLD-401 by the end of 2026.
"We continue to advance the RedTail platform and its breakthrough capabilities through our lead asset, CLD-401," said Eric Poma, PhD, Chief Executive Officer of Calidi. "We expect to file an IND for CLD-401 by end of 2026 and enter the clinic shortly thereafter."
"The data we will present at AACR (Free AACR Whitepaper) will characterize the pharmacokinetic pattern of IL-15 SA expression and resulting changes in the TME" said Antonio F. Santidrian, PhD, Chief Scientific Officer and Head of Technical Operations at Calidi. "The ability of CLD-401 to induce high levels of IL15-SA expression in the TME but not systemically may dramatically alter the therapeutic window of cytokine treatment."
The Company continues to expand the functionality of the RedTail platform and is also actively pursuing strategic partnerships to accelerate clinical development and broaden the impact of its RedTail platform.
