• Presented preclinical data at the American Society of Clinical Oncology (ASCO) on CLD-401 demonstrating biological efficacy IL-15 superagonist delivery to metastatic tumor sites and reduced immune clearance through engineered CD55 membrane expression; IND filing expected by the end of 2026
• Received FDA Fast Track Designation for CLD-201, a first-in-class stem-cell loaded intratumoral viral therapy for the treatment of patients with soft tissue sarcoma
• Raised $4.6 million gross proceeds through a warrant inducement offering with existing investors that further strengthens the company’s balance sheet and extends its runway
  

SAN DIEGO, Aug. 08, 2025 (GLOBE NEWSWIRE) -- Calidi Biotherapeutics Inc. (NYSE American: CLDI) (“Calidi”), a clinical-stage biotechnology company pioneering the development of targeted therapies with the potential to deliver genetic medicines to distal sites of disease, today reported its second quarter 2025 operating and financial results and reviewed recent business highlights.

“We are extremely excited about the progress at Calidi,” said Eric Poma, PhD, CEO of Calidi Biotherapeutics. “We believe our RedTail platform, with its ability to protect virus from immune clearance and induce tumor lysis and the delivery of potent therapeutic genetic medicines to metastatic sites through systemic administration, will be a substantial breakthrough in the field of oncolytic viruses and tumor-targeted gene therapies. We look forward to leveraging our scientific, operational and capital markets experience to continue building on Calidi’s strong platforms.”

Second Quarter 2025 and Recent Corporate Developments

• Presented new preclinical data surrounding CLD-401, the first lead compound from Calidi’s proprietary RedTail platform, at the American Society for Clinical Oncology (ASCO) on May 30^th in Chicago, IL., demonstrating enhanced biological efficacy in syngeneic tumor models through the delivery of IL15 superagonist to metastatic tumors sites after systemic administration. Calidi also demonstrated the engineered expression of CD55 on the enveloped virus, allowing the virus to avoid immune clearance and enabling systemic administration. The systemic administration of the CD55-expressing enveloped virus allows Calidi to target metastatic disease patients with high unmet need.
• Raised $4.6 million in gross proceeds from a warrant inducement offering with existing investors despite a challenging financing environment for the biotech industry, increasing the total gross proceeds raised in all offerings in 2025 to $15.7 million.
• Granted Fast Track Designation to CLD-201 by the U.S. Food and Drug Administration (FDA) for the treatment of patients with soft tissue sarcoma.  CLD-201 is a first-in-class stem cell loaded intratumoral oncolytic viral therapy that has demonstrated significant advantages over current intratumoral oncolytic viral approaches. An IND for a Phase 1 study was successfully opened for CLD-201 in Q1-2025.
