I. To determine the prostate-specific antigen (PSA) response that is a 50% or more reduction from the baseline.
I. To determine the overall response as determined by the Prostate Cancer Working Group 2 criteria (PCWG2).
II. To evaluate the progression-free survival (PFS) and overall survival of CRPC patients treated with PDMX1001/niclosamide (niclosamide), abiraterone (abiraterone acetate) and prednisone.
III. To assess the toxicity of PDMX1001/niclosamide, abiraterone and prednisone given in combination.
IV. To evaluate molecular correlatives for patient response and outcomes through the analysis of patient baseline tumor specimens (diagnostic biopsy) along with serial blood specimens.
Patients receive abiraterone acetate orally (PO) once a day (QD), niclosamide PO twice a day (BID) and prednisone PO BID. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 3 months.

Experimental: Treatment (abiraterone acetate, niclosamide, prednisone)
Patients receive abiraterone acetate PO QD, niclosamide PO BID and prednisone PO BID. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.
Drug: Abiraterone Acetate
- PSA response rate [ Time Frame: Up to 2 years ]Percent of patients achieving greater than or equal to 50% PSA declines following initiation of treatment
- Incidence of dose limiting toxicity defined as any grade III non-hematologic toxicity not reversible to grade II or less within 96 hours, or any grade IV toxicity [ Time Frame: 4 weeks ]Graded according to National Cancer Institute Common Terminology Criteria for Adverse Events 4.0. Adverse events and adverse events of grade 3 or higher will be listed for each patient and summarized by body system in a frequency table.
- Overall response as determined by PCWG2 criteria [ Time Frame: From the time measurement criteria are met for complete response/partial response (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented, assessed up to 2 years ]
- Overall survival [ Time Frame: Up to 2 years ]Will be estimated using the product-limit method of Kaplan and Meier; medians and 95% confidence intervals will be computed.
- PFS [ Time Frame: Up to 2 years ]Will be estimated using the product-limit method of Kaplan and Meier; medians and 95% confidence intervals will be computed. Will be compared with the historic control of abiraterone alone.
