• Preclinical models have demonstrated the ability to resist oncolytic virus inactivation by human serum and target diverse tumor types
• Novel therapeutic approach allows for ease of administration, increased cost-effectiveness, and the ability to reach a broad patient population
• Systemic enveloped solution builds upon Calidi’s years of experience in effectively using cells to protect oncolytic viruses from being neutralized by the patient’s immune system

SAN DIEGO / Feb 12, 2024 / Business Wire / Calidi Biotherapeutics, Inc. (NYSEAM: CLDI) (“Calidi”), a clinical-stage biotechnology company developing a new generation of targeted immunotherapies, today announced an upcoming presentation to provide details on the development of the Company’s systemic enveloped oncolytic virotherapy platform which has the potential to provide a universal treatment for a broad range of advanced tumor types. Stephen Thesing, Chief Business Officer of Calidi, will be presenting at the Biocom Global Life Science Partnering & Investor Conference on February 28, 2024 at 3:00 p.m. PT, to discuss the Company’s newly announced systemic enveloped oncolytic virotherapy program targeting all tumor types, including advanced metastatic disease, and provide an update on the clinical development progress of Calidi’s CLD-101 (NeuroNova) and CLD-201 (SuperNova) programs.

Calidi's systemic enveloped virotherapy program, ImmunoNova, leverages extensive experience in utilizing cells to protect, potentiate and deliver virotherapies. Utilizing an engineered and enveloped vaccinia virus, ImmunoNova shows promising potential in targeting advanced metastatic disease across the body, while maintaining survival in the bloodstream. Preclinical models have demonstrated ImmunoNova's efficacy in transforming tumor immune microenvironments and eradicating distant and diverse tumors. In addition, the program exhibits synergistic potential with other immunotherapies, including cell therapies, enhancing its ability to attack and eliminate disseminated solid tumors.

“Calidi's groundbreaking systemic enveloped virotherapy holds immense promise in revolutionizing the treatment landscape for cancer patients with advanced solid tumors. By priming the tumor microenvironment, our therapy empowers immune cells, activates the immune system, and ultimately eliminates tumors,” said Allan Camaisa, CEO and Chairman of the Board of Calidi Biotherapeutics. “We are encouraged by the promising preclinical data from our new program and while continuing to advance our existing clinical pipeline to fight cancer on all fronts.”
