Study Design

Endpoint classification safety study
Intervention model single group assignment
Masking open label
Primary purpose treatment
muscadine plus grape skin extract
Phase I: Dose escalation starts at 500mg pills given by mouth once daily for 28 days per cycle Phase II: to be determined after maximum tolerated dose in Phase I is established

Primary Outcomes

(Phase I) Maximum Tolerated Dose
time frame: Approximately 7 months to reach MTD
(Phase II) Define the effects of placebo and two different daily doses of Muscadine Plus on PSA doubling time
time frame: Up to 3 years

Secondary Outcomes

(Phase I)Number of Participants with Adverse Events as a Measure of Safety and Tolerability
time frame: Up to 3 years
(Phase II) To estimate other measures of PSA kinetics
time frame: Up to 3 years

Eligibility Criteria

Male participants at least 18 years old.

Inclusion Criteria: - Histologically or cytologically confirmed adenocarcinoma of the prostate. - Undergone definitive treatment (surgery, surgery with radiation therapy, cryotherapy, radiation therapy or brachytherapy) for the primary prostate tumor. - Rising PSA on a minimum of 3 time points (including screening psa) within the 12 months prior to study initiation. - > 18 years of age. - Life expectancy of greater than 6 months. - ECOG performance status 0, 1 or 2. - Testosterone level of ≥1.5 ng/mL at screening. - Adequate kidney, liver and bone marrow function - Agrees to abstain from other commercially available MP products while participating in this study. - Subject's use of other dietary/herbal supplements (e.g. saw palmetto, selenium, etc) has been stable for at least 2 months prior to screening and the subject agrees not to stop or change the dose(s) while participating in the study. - Signed a written informed consent document and agrees to comply with requirements of the study. Exclusion Criteria: - Known radiographic evidence of metastatic disease, except for presence of positive lymph nodes from the surgical pathology. Pelvic/intraperitoneal lymph nodes less than 2.0 cm maybe considered nonspecific and the patient would be eligible - Receipt of any therapies that modulate testosterone levels (e.g., androgen ablative/anti-androgen therapy, 5 alpha reductase inhibitors) for a minimum of 6 months prior to study - Prior or concomitant treatment with experimental drugs, high dose steroids, or any other cancer treatment within 4 weeks prior to the first dose of the study product - Consumption of Muscadine Plus over the past 2 months - Known allergy to muscadine grapes or ellagic acid - Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements - Negative PSA doubling time (1 time point may be excluded per 3e inclusion criteria)
