Recruiting at 7 sites Phase 1 Metastatic Castration Resistant Prostate Cancer

Metastatic Castration Resistant Prostate Cancer study: FX-111

Official title A Study in Patients With Metastatic Castration-Resistant Prostate Cancer

ClinicalTrials.gov ID: NCT07719361

What this study is testing

What is FX-111?

FX-111 is an investigational oral medicine being studied as a potential treatment for metastatic castration-resistant prostate cancer.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study wants to see if FX‑111 is safe and how the body processes it, and whether it can slow the cancer’s growth.
Who it's for
Adult men whose prostate cancer has spread and stopped responding to hormone treatment.
What's involved
Participants will take FX‑111 by mouth every day and attend regular check‑ups, including physical exams and blood tests, to monitor side effects and tumor status.
Time commitment
The trial lasts several months, with scheduled visits for medication, health checks, and lab work throughout the study period.
