Testing ACE-232 for advanced prostate cancer treatment

A Phase 1 Study to Assess the Safety, Pharmacokinetics, Pharmacodynamics, and Preliminary Efficacy of ACE-232 in Patients With Metastatic Castration-Resistant Prostate Cancer (CRPC)

Phase 1 Interventional Acerand Therapeutics Limited · NCT06801236

This study is testing a new treatment called ACE-232 to see if it is safe and effective for people with advanced prostate cancer that has not responded to other therapies.

What this trial studies

This open-label, phase 1 study evaluates the safety and tolerability of ACE-232 in patients with metastatic castration-resistant prostate cancer (mCRPC). It consists of two parts: Phase 1A focuses on dose escalation to determine the maximum tolerated dose, while Phase 1B treats patients with AR gene alterations at different dose levels to establish the recommended Phase 2 dose. The study also assesses pharmacokinetics and pharmacodynamics to understand the drug's effects better.

Who should consider this trial

Good fit: Ideal candidates include men with metastatic castration-resistant prostate cancer who have undergone prior treatments and are suitable for investigational therapies.

Not a fit: Patients with spinal cord compression, known brain metastases, or those currently receiving other anti-cancer treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with difficult-to-treat mCRPC.

How similar studies have performed: Other studies have shown promise with similar approaches in treating advanced prostate cancer, but this specific treatment is novel.
