Item 1.01. Material Agreements.
On October 1, 2025, the board of directors (the “Board”) of Kairos Pharma, Ltd., a Delaware Corporation (“Kairos” or the “Company”), approved the entry of Kairos and its wholly-owned subsidiary, Enviro Therapeutics, Inc. (“Enviro”), into a novation agreement (the “Cedars Novation Agreement”) with Cedars-Sinai Medical Center (“Cedars”). The Cedars Novation Agreement was entered into on October 1, 2025, but effective as of April 17, 2025 and was entered into in order to transfer the exclusive license of two patents from Enviro, as the original licensee, to Kairos, as the new licensee. As the new licensee of the two patents, Kairos accepted and assumed all obligations and liabilities that may arise under the exclusive license agreements from Enviro and Enviro is relived of all of its liabilities and obligations under the license agreements. The two patents subject to the Novation Agreement include the “Exclusive License Agreement to the Compositions and Methods for Treating Diseases and Conditions by Depletion of Mitochondrial or Genomic DNA from Circulation and for Detection of Mitochondrial or Genomic DNA,” originally dated June 2, 2025, as amended to date; and the “Exclusive License Agreement to Sensitization of Tumors to Therapies Through Endoglin Antagonism,” originally dated June 2, 2021, as amended to date.
In addition, on October 1, 2025, the Board approved the Company’s entry into a novation agreement (the “Tracon Novation Agreement”) with Tracon Pharmaceuticals, Inc. (the “Tracon”) and Enviro pursuant to which Enviro’s rights and obligations in the license and supply agreement between Tracon, Enviro and Kairos, originally dated May 21, 2021, as amended to date (the “Tracon License Agreement”), were transferred to Kairos and Enviro was relieved of any further liabilities or obligations under the license and supply agreement. Under the Tracon License Agreement, Tracon had granted Enviro exclusive access to its TRC105 and CD105 technologies, which Kairos has now assumed pursuant to the Tracon Novation Agreement.
The foregoing summary of the Cedars Novation Agreement and the Tracon Novation Agreement do not purport to be complete and are qualified in their entirety by reference to the full text of such agreements, which are attached hereto as Exhibits 10.1 and 10.2 and are incorporated by reference herein.

Kairos Pharma to Present Positive Safety and Efficacy Data from Phase 2 Prostate Cancer Trial at ESMO 2025
Los Angeles, CA — October 7, 2025 — Kairos Pharma, Ltd. (NYSE American: KAPA), a clinical-stage biopharmaceutical company dedicated to addressing resistance to current cancer therapeutics, today announced that it has been selected to present at the European Society for Medical Oncology (ESMO) Congress. Kairos’s presentation, titled, “Preliminary safety and clinical activity from a Phase 2 study of apalutamide and carotuximab in advanced, castration-resistant prostate cancer” will take place in Berlin, Germany on October 17–21, 2025.
Prostate cancer remains one of the most diagnosed cancers in men, with over a million new cases annually in the U.S. alone. Resistance to androgen-targeted therapies represents a major clinical challenge in patients with metastatic castration-resistant prostate cancer (mCRPC).
The presentation will highlight results from an interim analysis of the randomized Phase 2 trial evaluating ENV105 (carotuximab), a first-in-class CD105 antagonist. The trial is enrolling 100 men at Cedars-Sinai Medical Center, City of Hope, and Huntsman Cancer Institute at the University of Utah with mCRPC who had progressed on prior hormone therapies. Patients are randomized to receive apalutamide in the presence or absence of ENV105.
“The data we will be presenting at the 2025 ESMO Congress demonstrates encouraging safety and early efficacy findings from our Phase 2 trial,” said Neil Bhowmick, PhD, Kairos Pharma CSO. “This is an important venue for us to share the therapeutic potential of ENV105 for patients with few remaining treatment options after hormone therapy resistance develops.”

Kairos Pharma is a biopharmaceutical company advancing a pipeline of targeted therapies for cancer patients with high unmet medical needs. Our mission is to bring safe, effective, and science-driven solutions that improve the efficacy of existing standard of care to the most challenging forms of cancer.
