• RTNova, an innovative systemic antitumor enveloped virotherapy, unlocks new possibilities in cancer therapy
• RTNova addresses challenges posed by untargetable and untreatable metastatic diseases, offering a potential transformative solution with wide-ranging applications

SAN DIEGO, Oct. 24, 2024 (GLOBE NEWSWIRE) --  Calidi Biotherapeutics Inc. (NYSE American: CLDI) (“Calidi”), a clinical-stage biotechnology company developing a new generation of targeted antitumor virotherapies and viral vectors, will present data supporting RTNova (CLD-400), the company’s systemic antitumor virotherapy platform, at the International Oncolytic Virotherapy Conference (IOVC) in Rotterdam, Netherlands, October 27-30, 2024, and at Immuno US 2024 in San Diego, October 28-30, 2024. In addition, a poster will be presented at the Society for Immunotherapy of Cancer (SITC) Annual Meeting in Houston, November 6-10, 2024.

Leading the presentations will be Antonio F. Santidrian, Ph.D., Calidi’s Chief Scientific Officer, and Duong H. Nguyen, Ph.D., Calidi’s Senior Director of Translational Research and Innovation. Dr. Santidrian and Dr. Nguyen have been instrumental in advancing the development of Calidi’s RTNova platform.

RTNova is a systemic treatment designed for reduced elimination by the humoral immune system. It targets multiple tumor sites, killing tumor cells while altering the tumor immune microenvironment. This novel therapeutic approach not only facilitates easier administration but also broadens the potential patient population who can benefit from this treatment.

“RTNova represents a groundbreaking advancement in cancer therapy, offering a systemic approach that enables us to target and treat metastatic tumors that were previously untouchable,” said Dr. Santidrian. “RTNova’s ability to fundamentally change the tumor microenvironment while delivering therapeutic viruses to multiple tumor sites has the potential to unlock new possibilities for patients facing some of the most challenging cancers. Ultimately, we believe RTNova has the potential to transform how we address previously untreatable metastatic diseases.”
