CXCR1/2 inhibitor plus enzalutamide for abiraterone-resistant metastatic prostate cancer

Official title: A Phase 2, Single-Arm Study of the CXCR1/2 Inhibitor SX-682 Plus Enzalutamide in Men with Abiraterone-Resistant Metastatic Castration Resistant Prostate Cancer (mCRPC)

Funded at Syntrix Biosystems, INC. · NIH-11370143 · Data updated 2026-11-12

A phase 2 study tests whether adding SX-682 to enzalutamide helps men with advanced prostate cancer that no longer responds to abiraterone.

Who could benefit from this research

Could help

American men with metastatic castration-resistant prostate cancer who progressed on abiraterone therapy and are geschikte for combined SX-682 and enzalutamide treatment.

Less likely to help

Patients whose cancer does not respond to CXCR1/2 inhibition or who experience intolerable side effects may not benefit.

What this research studies

This study investigates whether combining a CXCR1/2 inhibitor (SX-682) with enzalutamide can extend benefits for men whose metastatic castration-resistant prostate cancer has progressed after abiraterone therapy. It uses a single-arm design to evaluate safety and preliminary effectiveness in the target population. Participants would receive the oral SX-682 alongside ongoing enzalutamide, with regular monitoring for responses and adverse events. The goal is to find a treatment option that works differently from current AR-targeted therapies to delay disease progression and improve survival. Results could inform future trials and potential new standards of care for this patient group.

Why it matters

Potential benefit: If successful, the combination could provide longer disease control and improved survival for men with abiraterone-resistant mCRPC.

How similar studies have gone: Prior data support targeting CXCR1/2 in prostate cancer, but this exact combination is early-stage, making results uncertain but promising.
