Should l Buy CLDI?
Calidi Biotherapeutics will present new data at the American Association of Cancer Research, AACR, annual meeting in San Diego, California on April 21 2026. The Company showcased new data on CLD-401, a systemically delivered oncolytic virus that is designed to express high levels of IL-15 superagonist only in the tumor microenvironment, currently in IND-enabling studies. The Company expects to file an IND for CLD-401 by the end of 2026. Data at AACR detailed the immune changes in the TME induced by CLD-401 including the recruitment and activation of NK, NK-T, and gamma delta (gammadelta) T-cells that lead to a therapeutic response in the immunocompetent animal models. In addition to IL-15 SA delivery with CLD-401, the RedTail platform has also been shown to enable in situ expression of tumor-targeted T cell engagers, as demonstrated in a separate AACR presentation focused on the CLD-501 program

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.
