Kairos Pharma Ltd. (NYSE American: KAPA) announced positive interim efficacy data from its ongoing Phase 2 trial evaluating ENV-105 in combination with apalutamide in patients with metastatic castration-resistant prostate cancer (mCRPC). The analysis revealed a statistically significant difference in progression-free survival (PFS), with a median PFS of 17.7 months for patients receiving ENV-105 plus apalutamide compared to two months for those receiving apalutamide alone (P=0.0008). This marked improvement suggests that ENV-105, an antibody targeting CD105, may effectively reverse drug resistance and restore the effectiveness of standard therapies.
In response to these findings, Kairos Pharma has modified the Phase 2 protocol to enroll patients earlier in disease progression. Patients who experience a PSA increase following upfront treatment with an androgen signaling inhibitor will now be randomized to receive either enzalutamide alone or enzalutamide in combination with ENV-105. According to the company, this change is intended to expand the eligible patient population and facilitate enrollment, with completion of the Phase 2 trial targeted in or before the fourth quarter of 2027.

Based in Los Angeles, California, Kairos Pharma is at the forefront of oncology therapeutics, utilizing structural biology to overcome drug resistance and immune suppression in cancer. The company's lead candidate, ENV-105, targets CD105—a protein identified as a key driver of resistance and disease relapse in response to standard therapy. By targeting CD105, ENV-105 aims to reverse drug resistance and restore the effectiveness of standard therapies across multiple cancer types.

The significance of these interim results extends beyond Kairos Pharma. Prostate cancer remains a leading cause of cancer death among men, and metastatic castration-resistant prostate cancer is particularly challenging to treat due to resistance to conventional androgen deprivation therapies. The substantial PFS benefit observed with ENV-105 plus apalutamide could represent a new treatment paradigm for patients who have become resistant to standard therapies. If the Phase 2 trial continues to demonstrate such efficacy, ENV-105 could become a valuable addition to the treatment landscape, potentially improving outcomes for a large patient population.
For investors, the positive interim data and protocol amendment signal progress in Kairos Pharma's clinical development program. The company's focus on addressing drug resistance through CD105 targeting differentiates it in the competitive oncology space.
