What this trial studies

This Phase 1, open-label trial gives single oral doses of HRS-5041-103 to men with metastatic castration-resistant prostate cancer to characterize safety, tolerability, pharmacokinetics and preliminary anti-tumor activity. Participants must have adequate bone marrow, liver and other organ function and must not receive other anti-cancer treatments close to dosing. Key exclusions include uncontrolled hypertension, recent chemotherapy/targeted therapy/immunotherapy or active gastrointestinal conditions that affect oral absorption. The trial is sponsored by Atridia Pty Ltd and is recruiting at three clinical sites in Australia.

Who should consider this trial

Good fit: Men with metastatic castration-resistant prostate cancer who have adequate organ function, can swallow oral medication, and who have not received recent anti-cancer therapies would be the ideal candidates.

Not a fit: Patients with uncontrolled hypertension, active gastrointestinal disease affecting drug absorption, recent chemotherapy or immunotherapy within four weeks, or known allergy to the drug may not be eligible or benefit from participation.

Why it matters

Potential benefit: If successful, HRS-5041-103 could become a new oral treatment option that slows disease progression for men with metastatic castration-resistant prostate cancer.

How similar studies have performed: HRS-5041-103 appears to be an early-phase, relatively novel investigational drug with limited public clinical data, although other oral agents have shown benefit in later-phase trials for advanced prostate cancer.
