About this trial
The goal of this clinical trial is to find out if FX-111 is safe enough to permit further studies in adult male participants with metastatic castration-resistant prostate cancer (mCRPC). It will also study the drug's pharmacokinetics (how the body breaks down FX-111) and how well FX-111 treats mCRPC. The main questions it aims to answer are:
What are the side effects of FX-111?
Does FX-111 work to reduce or prevent progression of mCRPC?
The study doctor will oversee participants' treatment with FX-111 and ask about any side effects. Participants will take FX-111 every day by mouth and will have regular physical and laboratory examinations to check health and tumor status.
Eligibility criteria
Qualifiers
Confirmed adenocarcinoma of the prostate.
PSA levels ≥ 2 ng/mL at screening visit.
Progressing PSA, defined as two consecutive increases in the most recent PSA measurements taken at least 1 week apart.
Progressed on Androgen Deprivation Therapy (ADT) and at least one prior potent Androgen Receptor (AR) pathway inhibitor given in castration-sensitive prostate cancer setting or approved for castration-resistant prostate cancer (eg, apalutamide, darolutamide, abiraterone, enzalutamide).
Disqualifiers
Predominance of small cell carcinoma of the prostate/neuroendocrine prostate cancer in most recent tumor biopsy.
Participants with brain metastases that require ongoing treatment with radiation or high-dose steroids.
Not recovered from side effects of prior surgery or cancer treatments.
