Announced demonstrated ability to deliver transient gene therapy (payload) to tumors using systemic antitumor virotherapy platform Filed IND in March 2025 for CLD-201 company sponsored Phase 1 trial to treat multiple solid tumors Commencement of recruitment for Phase 1 trial in patients with newly diagnosed high-grade glioma at Northwestern University hospital 14 patients enrolled in Phase 1 trial conducted by City of Hope to treat recurrent high-grade glioma SAN DIEGO, March 31, 2025 (GLOBE NEWSWIRE) -- Calidi Biotherapeutics Inc. (NYSE American: CLDI) (“Calidi”), a clinical-stage biotechnology company developing a new generation of targeted immunotherapies, today reported its fourth quarter and full-year 2024 operating and financial results and reviewed recent business highlights. “Calidi continues to make great progress on all three of our platforms; our systemic asset CLD-400 proved it can deliver a gene therapy payload to targeted tumors, we filed an IND for our solid tumor asset CLD-201, and our CLD-101 program treating high-grade glioma is advancing in two Phase 1 trials,” said Allan Camaisa, CEO and Chairman of the Board of Calidi Biotherapeutics. “We think our multi-modal mechanism of action is a game changer in treating multiple deadly cancers, including metastatic cancer and lung cancer, solid tumors and high-grade glioma.” Fourth Quarter 2024 and Recent Corporate Developments New data showed that a single dose of a tumor-selective triple knockout (“3KO”) RT virus genetically engineered to encode a specific immune-boosting payload (undisclosed) increased the antitumor immune response. These increased shifts in immune composition, driven by virotherapy encoding a payload, ultimately led to complete eradication of certain tested tumors in the preclinical model. In March 2025, Calidi filed an IND for a company sponsored, open label dose escalation trial of CLD-201 in adult patients with solid tumors, specifically with the indications of breast cancer, head & neck squamous cell carcinoma, and soft tissue sarcoma. In February 2025, Northwestern University hospital started recruiting for the CLD-101 Phase 1 clinical trial in patients with newly diagnosed high-grade glioma, an aggressive and often fatal form of brain cancer. This physician-led and NCI sponsored clinical trial, led by prominent experts Dr. Maciej Lesniak and Dr. Roger Stupp, builds on the promising results from a prior Phase 1 trial involving 12 patients treated with a single dose of CLD-101 published in the prestigious journal The Lancet Oncology. City of Hope and Calidi announced the 14th patient treated in a physician-sponsored Phase 1 trial assessing the safety and feasibility of a multi-dosing regimen to treat recurrent high-grade glioma. This program has secured $12 million award from the California Institute for Regenerative Medicine (CIRM) to support this groundbreaking study.
