Kairos Pharma to Present Positive Safety and Efficacy Data from Phase 2 Prostate Cancer Trial at ESMO 2025

Kairos Pharma, Ltd. (NYSE: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."
