On December 13, 2023 Calidi Biotherapeutics, Inc. (NYSE American: CLDI or "Calidi"), a clinical-stage biotechnology company developing a new generation of targeted immunotherapies, reported three presentations on Calidi’s NeuroNova (NNV) and SuperNova (SNV) allogeneic stem cell-based virotherapy platforms at the upcoming 8th Oncolytic Virotherapy Summit to be held December 12-14, 2023 in Boston, Mass (Press release, Calidi Biotherapeutics, DEC 13, 2023, View Source [SID1234638548]). During presentations at the summit, Jana Portnow, M.D., principal investigator, professor in the Department of Medical Oncology & Therapeutics Research and co-director of the Brain Tumor Program at City of Hope Comprehensive Cancer Center, will present the clinical trial design and safety of a Phase 1 study opened in June 2023, using multiple doses of Calidi’s NeuroNova administered intracerebrally, to recurrent high grade glioma patients. Antonio F. Santidrian PharmD, Ph.D., Chief Scientific Officer and Boris R. Minev, M.D., President, Medical & Scientific Affairs, will present updates on the company’s targeted immunotherapies, leveraging allogeneic stem cells to target tumors and deliver anti-cancer payloads in the form of cancer-killing viruses.

"Our cell-based virotherapeutics are designed to target tumors directly and to help the immune system recognize and attack distant tumor sites," said Boris R. Minev. M.D, President, Medical & Scientific Affairs of Calidi Biotherapeutics. "We are testing this approach in high-grade glioma and anticipate initiating a new clinical trial in several difficult-to-treat advanced solid tumors in the second half of 2024."

The company has four clinical and preclinical programs utilizing different viruses and different types of allogeneic stem cells to overcome the inactivation of Calidi’s virotherapies by the patients’ immune system. This unique approach utilizes specially selected viruses to kill tumor cells and modify the tumor microenvironment, thus enabling the release of tumor antigens. Subsequently, the antigen-presenting cells are able to induce potent antitumor immune responses to detect, attack, and destroy metastatic tumor sites.

Updates to be presented at the upcoming 8th Oncolytic Virotherapy Summit include:

Progress in Recurrent High Grade Glioma (HGG) Trial. Calidi’s collaborator: City of Hope Comprehensive Cancer Center dosed the first patient in June 2023 in a Phase 1 clinical trial of NeuroNova (NNV2) and has dosed 6 patients to-date. Dr. Portnow will present an initial update on this trial. Of note, Calidi holds an exclusive worldwide licensing agreement with City of Hope and the University of Chicago for patents covering the NSC-CRAd-S-pk7 technology (NeuroNova).
Plans to Commence a Dose Escalation Trial in Newly Diagnosed HGG in 1H 2024. Calidi plans to commence a Phase 1b/2 clinical trial for NeuroNova (NNV1) in collaboration with Northwestern University during the first half of 2024. The Phase 1b dose escalation lead portion of this anticipated trial will explore the final dosing regimen for NNV1, including the feasibility of repeated dosing.
Plans to File IND Application for Clinical Trial Initiation in Advanced Solid Tumors in 2H 2024. SuperNova (SNV1) is the company’s first internally developed preclinical product candidate utilizing the SuperNova Delivery Platform. The company plans to file its IND application for the clinical development of CLD-201 to enable the initiation of a Phase 1 clinical trial for SNV1 during the second half of 2024.
Systemic Programs for Metastatic Solid Tumors. Calidi is currently engaged in early discovery research involving its next generation cell-based virotherapies. The company’s research is focused on engineered oncolytic vaccinia virus to increase the tumor specificity and oncolytic potency with improved systemic anti-tumor immunity.
