Brief summary

A proof of concept clinical trial to assess the synergism of curcumin (CURC) and ursolic acid (UA). Before further testing within formal cancer clinical trials, we must (1) evaluate the bioavailability and safety, (2) confirm the presence of metabolites in the target organ, and (3) validate the appropriate mechanism of effect

Detailed description

Once a subject is identified that may meet eligibility criteria, the physician and/or study investigators will be alerted to the potential candidate and will introduce the study to the patient at their standard of care (SOC) appointment or via telephone. Patients will be given the option for enrollment and if they agree, informed consent will be discussed and obtained provided they meet all inclusion/exclusion criteria. Following informed consent, subjects will be assigned to one of the following cohorts: Cohort 1: • Ursolic Acid (150 mg) BID (twice a day) Cohort 2: • Curcumin (600 mg) BID Cohort 3: • Ursolic Acid (150 mg) and Curcumin (600 mg) BID The study team aim to enroll 10 subjects who will complete the study into each cohort for a total of 30 completers. Subjects will be enrolled on a rolling basis with the first ten subjects assigned to Cohort 1, the next ten subjects assigned to Cohort 2, and the last 10 subjects assigned to Cohort 3.

Design outcomes

Primary

MeasureTime frameDescription
Number, frequency, duration, and relation of toxicity eventsBaseline to 8 weeksSafety will be compared to evaluate the number, frequency, duration, and relation of toxicity events to CURC/UA combination, as defined by the Common Terminology Criteria for Adverse Events (CTCAE) v 4.03.
Peak serum concentrationBaseline to 8 weeksDose response curve representing the pharmacokinetic parameter peak serum concentration (Cmax) of ursolic acid, curcumin, and their metabolites will be graphed.
Time to reach peak serum concentrationBaseline to 8 weeksThe pharmacokinetic parameter, the area under the curve (Tmax) representing the time it takes to reach Cmax of ursolic acid, curcumin, and their metabolites will be graphed.
Half-lifeBaseline to 8 weeksThe pharmacokinetic parameter, half-life of ursolic acid, curcumin, and their metabolites will be graphed.

Secondary

MeasureTime frameDescription
Levels of UA, CURC, and metabolites in prostate tissueBaseline to 8 weeksIdentify the presence and levels of UA, CURC and their metabolites in prostate tissue using HPLC.
Immunohistochemistry measurementBaseline to 8 weeksImmunohistochemistry of proportion of nuclear p65 NFkB staining before and after prostatectomy on FFPE samples will be completed.
