GeoVax Labs, Inc. has entered into an exclusive worldwide license agreement with Emory University for intellectual property covering the use of Gedeptin in combination with immune checkpoint inhibitors. The licensed technology supports the use of gene-directed enzyme prodrug therapy to enhance the anti-tumor activity of checkpoint blockade, which could potentially convert immunologically 'cold' tumors into more responsive targets.
The exclusive license provides GeoVax with global rights to patent applications and associated know-how covering the combination of Gedeptin with immune checkpoint inhibitors within a defined field of use. This intellectual property estate is intended to support GeoVax's current and planned clinical programs evaluating Gedeptin in combination with ICIs, including its recently announced neoadjuvant strategy in head and neck cancer and ongoing evaluation of additional solid tumor indications.
David A. Dodd, Chairman and Chief Executive Officer of GeoVax, stated that as checkpoint inhibitors continue to move earlier in treatment paradigms, including first-line and neoadjuvant settings, Gedeptin's localized tumor-debulking and immune-sensitizing mechanism may provide an important opportunity to enhance and extend immune checkpoint inhibitor efficacy. The company has previously reported encouraging clinical and translational data demonstrating that Gedeptin's intratumoral delivery approach can induce localized tumor cell death while promoting immune activation within the tumor microenvironment.
GeoVax has previously announced plans to evaluate Gedeptin in combination with immune checkpoint inhibitors in a Phase 2 neoadjuvant clinical trial in head and neck squamous cell carcinoma, as well as preclinical assessments in additional solid tumor settings. The Emory license provides a strengthened intellectual property foundation to support these efforts and potential future partnerships. The company continues to evaluate strategic collaboration opportunities related to both the clinical development and potential commercialization of Gedeptin-based combination therapies.
Gedeptin is a gene-directed enzyme prodrug therapy delivered intratumorally using a non-replicating viral vector encoding purine nucleoside phosphorylase. Following administration of a systemically delivered prodrug, the encoded enzyme converts the prodrug into a cytotoxic agent directly within the tumor microenvironment. This localized approach is designed to selectively destroy tumor cells while promoting immune recognition and minimizing systemic toxicity. Gedeptin has received Orphan Drug Designation for oral and pharyngeal cancers.

The company's priority program is GEO-MVA, a Modified Vaccinia Ankara-based vaccine targeting Mpox and smallpox, which is advancing under an expedited regulatory pathway with plans to initiate a pivotal Phase 3 clinical trial in the second half of 2026.
