Calidi Biotherapeutics Granted U.S. Patent for Proprietary Therapeutic Delivery Platform, Strengthening Company's Intellectual Property Position in Immunotherapy

Calidi Biotherapeutics, Inc., a clinical-stage biotechnology company pioneering the development of stem cell-based delivery of oncolytic viruses, has been granted a new patent (No. US 11,285,194, Combination immunotherapy approach for treatment of cancer) by the U.S. Patent and Trademark Office (USPTO) related to its proprietary SuperNova (SNV) technology platform. The enhanced oncolytic virotherapy delivery platform was designed to provide and improve therapeutic treatments for multiple cancer indications. Calidi's product candidates are in the early stages of development and have not yet been approved by the U.S. Food and Drug Administration (FDA).

The SNV platform is composed of allogeneic, adipose-derived mesenchymal stem cells (AD-MSC) loaded with an oncolytic agent, such as the vaccinia virus, and is anticipated to be used in combination with various immunotherapy agents, including blocking antibodies. The SNV platform is designed to shield oncolytic viral payloads from the immune system, thereby efficiently delivering immuno-oncology therapy directly to tumor sites.

"Calidi's Supernova platform has been developed through years of research in stem cell delivery and potentiation of oncolytic viruses and has the potential to revolutionize the treatment of solid tumors," said Allan J. Camaisa, CEO and Chairman of Calidi. "The addition of this patent further strengthens our intellectual property position and solidifies the opportunity to use our platform technology in advancing therapeutic discovery and development through the FDA approval process."

The Calidi approach aims to induce a durable anti-tumor immune response. In pre-clinical studies, Calidi's SNV platform-based product candidates have been shown to shield the oncolytic viruses from destruction by the patient's immune system, supporting efficient viral replication within the stem cells prior to delivery to tumor sites. Once there, the viral payload selectively destroys tumor cells and stimulates the patient's immune system to attack the tumor.

"Our outstanding team of doctors and scientists have invested years of intensive research and groundbreaking work to develop Calidi's SNV platform technology," said Boris Minev, M.D., President, Medical and Scientific Affairs at Calidi, and a patent inventor. "This patent represents the culmination of their impressive expertise, dedication, and passion, and will help the company continue to advance its novel discovery programs."
