Kairos Pharma Ltd. (NYSE American: KAPA) has released a comprehensive update on its clinical progress and 2026 outlook through a shareholder letter from CEO John Yu, M.D. The clinical-stage biopharmaceutical company reported significant interim results from its Phase 2 trial evaluating ENV105 in combination with apalutamide for advanced metastatic prostate cancer. The data revealed an impressive 86% clinical benefit rate among treated patients, accompanied by durable progression-free survival and no observed dose-limiting toxicities.
The positive safety and efficacy findings, which were presented at the European Society for Medical Oncologists Meeting, indicate that ENV105 may enhance the effectiveness of standard care while maintaining strong tolerability profiles. This combination approach addresses a critical need in oncology by potentially extending treatment efficacy for patients with advanced prostate cancer who often face limited options as their disease progresses. The company continues to actively recruit patients for the trial, with enrollment expected to reach 100 participants across leading cancer centers throughout the United States.
ENV105 represents a novel therapeutic approach in cancer treatment, functioning as an antibody that specifically targets CD105, a protein identified as a key driver of resistance to various cancer treatments. The elevation of CD105 in response to standard therapy frequently results in treatment resistance and disease relapse, creating significant challenges in long-term cancer management. By targeting CD105, ENV105 aims to reverse drug resistance and restore the effectiveness of standard therapies across multiple cancer types, potentially transforming treatment paradigms for patients with limited options.
Beyond the prostate cancer program, Kairos Pharma is advancing ENV105 in a Phase 1 trial for lung cancer, addressing additional significant unmet medical needs in oncology. The company's strategic focus on utilizing structural biology to overcome drug resistance and immune suppression in cancer positions it at the forefront of innovative cancer therapeutic development.

The implications of these clinical developments extend beyond immediate patient benefit to potentially reshape treatment approaches for resistant cancers. The demonstrated combination of efficacy and safety in the Phase 2 trial suggests ENV105 could become an important component in the prostate cancer treatment arsenal, particularly for patients who have developed resistance to standard therapies. The ongoing expansion of clinical trials across multiple cancer types further underscores the platform's potential broad applicability in addressing treatment resistance mechanisms that affect numerous oncology indications.
