Kairos Pharma reports positive interim Phase 2 data for ENV-105 in prostate cancer
Kairos Pharma said interim Phase 2 data showed a statistically significant difference in progression-free survival for patients treated with ENV-105 plus apalutamide compared with apalutamide alone. The company also modified the trial protocol to enroll patients earlier in disease progression, with completion targeted in or before the fourth quarter of 2027.
Key points
- Median progression-free survival was 17.7 months with ENV-105 plus apalutamide versus 2 months with apalutamide alone (P=0.0008).
- The modified protocol enrolls patients after a PSA increase following upfront androgen signaling inhibitor treatment, randomized to enzalutamide alone or with ENV-105.
- Kairos Pharma targets completing the Phase 2 trial in or before the fourth quarter of 2027.
