Trial Summary
What is the purpose of this trial?This phase Ib trial is to find out the best dose decitabine/cedazuridine and possible benefits and/or side effects of decitabine/cedazuridine and enzalutamide in treating patients with castrate resistant prostate cancer that has spread to other places in the body (metastatic). Chemotherapy drugs, such as decitabine/cedazuridine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Enzalutamide blocks the use of androgen by the tumor cells. Giving decitabine/cedazuridine together with enzalutamide may reverse or help prevent the acquired therapeutic resistance that is observed when enzalutamide is used alone. Drug resistance occurs when cancer cells stop responding to a chemotherapy that had previously been effective.
Eligibility Criteria
Men over 18 with metastatic castrate resistant prostate cancer, showing disease progression. They must have good performance status (able to carry out daily activities), low testosterone levels if not on androgen deprivation therapy, adequate organ function, and the ability to swallow pills. Prior treatments for prostate cancer are allowed in some phases of the trial. Participants must use contraception.Inclusion Criteria

Participant Groups
The trial is testing the combination of decitabine/cedazuridine with enzalutamide to determine safe dosages and potential benefits or side effects in treating advanced prostate cancer that resists standard treatment. The goal is also to see if this combo can overcome resistance developed against enzalutamide alone.

Experimental Treatment
Group I: Treatment (decitabine and cedazuridine, enzalutamide)Experimental Treatment2 Interventions
Patients receive decitabine and cedazuridine PO QD on either days 1-3, 1-4, or 1-5 and enzalutamide PO QD on days 1-28. Treatments repeat every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity.
