Calidi Biotherapeutics presented new data at the American Association of Cancer Research, AACR, annual meeting in San Diego, California on April 19, 2026. The Company demonstrated new data on its approach of simultaneously activating T-cells while inducing the expression of T-cell engagers specifically in situ in the tumor microenvironment, TME. RedTail is Calidi's systemically delivered virotherapy platform designed to selectively target tumors, remodel the TME, and enable high-level expression of therapeutic genetic payloads directly at the tumor site while limiting peripheral exposure. CLD-401, the lead candidate derived from the RedTail platform, is engineered to express high levels of IL-15 superagonist, a known CD8 T-cell, NK cell, and gamma delta T-cell activator, in the TME. The Company expects to file an IND for CLD-401 by the end of 2026.

About CLDI
Calidi Biotherapeutics, Inc. is a clinical-stage immuno-oncology company. The Company is developing proprietary allogeneic stem cell-based and enveloped virus platforms to potentiate and deliver oncolytic viruses (vaccinia virus and adenovirus) and, potentially, other molecules to cancer patients. It is focused on developing two proprietary stem cell-based platforms and one enveloped vaccinia virus platform designed to protect the oncolytic virus, whether natural or engineered, from neutralization by the patient’s immune defenses, allowing for greater infection of the tumor cells and leading to a potential improvement in the antitumor activity of oncolytic viruses over traditional naked oncolytic virus therapies. Its product candidates include the CLD-101 product for high grade glioma (HGG), CLD-101 product for Recurrent HGG, CLD-201 product for solid tumors, CLD-301 (AAA) for multiple indications and CLD-400 (RTNova) for certain lung cancer and metastatic solid tumors.
