Brief summary

This randomized phase II trial studies pomegranate-extract pill in preventing tumor growth in patients with prostate cancer that is limited to a certain part of the body (localized), who have chosen observation as their treatment plan. The use of pomegranate-extract pill may slow disease progression in patients with localized prostate cancer.

Detailed description

PRIMARY OBJECTIVES: I. To determine the effect of pomegranate fruit extract (PFE) 1000 mg, taken daily for 1 year, on the plasma levels of insulin-like growth factor (IGF-1) from baseline to end of study (52 weeks) in participants undergoing active surveillance (AS) for early stage prostate cancer. SECONDARY OBJECTIVES: I. To assess compliance with a once daily oral administration of PFE versus placebo over a 52-week period of time. II. To assess the toxicity of PFE vs. placebo when taken daily for 52 weeks (+/- 1 week). III. To compare and correlate the effect of 52 weeks of daily dosing with PFE vs placebo on the end of study biopsy results including the presence or absence of tumor, the extent of tumor and Gleason scores. IV. To compare and correlate the modulation of the following biomarkers with response to PFE versus placebo in three areas of interest: tissue from a completely benign biopsy core, tumor tissue from a positive core, and normal tissue adjacent to tumor from a positive core; plasma: insulin-like growth factor 1/IGF binding protein 3 ratio (IGF-1/IGFBP-3 ratio); prostate tissue (normal and abnormal): apoptosis (CASPASE 3), Ki-67, 8OHdG, IGF-1R, androgen receptor, IGF-1, IGFBP-3, prostate specific antigen (PSA). V. Measure PFE constituents/metabolites in plasma and urine for evidence of accumulation (trough levels): ellagic acid, dimethyl ellagic acid, dimethyl ellagic acid glucuronide (DMEAG), urolithin A, urolithin A-glucuronide, urolithin B and urolithin B-glucuronide. VI. Measure PSA doubling time (PSA DT) in serum, using the calculation provided on the Memorial Sloan Kettering Cancer Center website. VII. To assess the feasibility of cancer chemoprevention trials in a population of men undergoing active surveillance for prostate cancer. VIII. Measurement of serum testosterone. OUTLINE: Patients are randomized to 1 of 2 groups. GROUP I: Patients receive pomegranate-extract pill orally (PO) once daily (QD) for 52 weeks (+/- 1 week). GROUP II: Patients receive placebo PO QD for 52 weeks (+/- 1 week).

Design outcomes

Primary

MeasureTime frameDescription
Change in Plasma IGF-1 From Baseline to Post-TreatmentBaseline to 12 monthsThe primary endpoint for modulation of intermediate endpoint biomarkers will be the change in the plasma levels of IGF-1 by a quantitative assay (ELISA) from pre-study to post-treatment. The difference between these time points for the placebo group and the pomegranate fruit extract (PFE) group will be tested using a two-sample t-test with normalizing transformation if necessary or Wilcoxon rank-sum test.

Secondary

MeasureTime frameDescription
Incidence of Adverse Events Graded Per Common Terminology Criteria for Adverse Events (CTCAE)Up to 1 yearPatient toxicity throughout the study will be summarized in several ways; the presence or absence of any toxicity, worst CTCAE grade, and strongest investigator-defined relationship will all be examined and characterized by treatment arm, and analyzed appropriately (Wilcoxon rank-sum for ordinal data, Fisher's exact test for dichotomous data, and log rank test for time to event data).
Change in Plasma Biomarker Levels From Baseline: IGFBP-3Week 13, Week 26, Week 39, Week 52Differences between the groups will be examined for the change from baseline with the appropriate tests; for dichotomous data Fisher's exact test will be used, for ordinal data Wilcoxon rank-sum test will be used, and for continuous data, and a two-sample t-test with normalizing transformation if necessary or Wilcoxon rank-sum test will be used.
Change in Plasma Biomarker Levels From Baseline: IGF-1/GFBP-3Week 13, Week 26, Week 39, Week 52Differences between the groups will be examined for the change from baseline with the appropriate tests; for dichotomous data Fisher's exact test will be used, for ordinal data Wilcoxon rank-sum test will be used, and for continuous data, and a two-sample t-test with normalizing transformation if necessary or Wilcoxon rank-sum test will be used.
Change in Total Serum Prostate Specific Antigen (PSA) From BaselineUp to 1 year
Change in Serum Testosteroneup to 1 year
Prostate Specific Antigen Doubling Time (PSA DT)up to 52 WeeksPSA DT will be determined from PSA values obtained during study participation (baseline and weeks 13, 26, 39 and 52). The secondary endpoint of PSA DT is based on the value at study completion (week 52 or at point of early termination). However, PSA DT will be determined starting at week 26 (the earliest time point with 3 values) and week 39 and recorded. PSA doubling time is a measure based on the slope of the PSA at multiple time points. If the slope is relatively flat, the predicted doubling time could be far beyond the length of the actual study. As such, the value is not limited to the time frame over which data is collected from the participant.

Change in Tissue Biomarker Levels: 8OHdG

Compare and correlate biomarker modulation in response to PFE versus placebo in three areas of interest: tissue from a completely benign biopsy core (benign in results), tumor tissue from a positive core (tumor in results), and normal tissue adjacent to tumor from a positive core (adjacent in results). Measurements for each are per nuclear (Nuc in results), cytoplasmic (Cyt in results), and cellular (Cell in results) basis. Differences between the groups will be examined for the change from baseline with the appropriate tests; for dichotomous data Fisher's exact test will be used, for ordinal data Wilcoxon rank-sum test will be used, and for continuous data, and a two-sample t-test with normalizing transformation if necessary or Wilcoxon rank-sum test will be used.

Time frame: Baseline to Week 52

Population: The number analyzed depends on the identification and recovery of relevant tissue type (benign, adjacent, tumor).

Differences between the groups will be examined for the change from baseline with the appropriate tests; for dichotomous data Fisher's exact test will be used, for ordinal data Wilcoxon rank-sum test will be used, and for continuous data, and a two-sample t-test with normalizing transformation if necessary or Wilcoxon rank-sum test will be used.

Time frame: Baseline to Week 52

Population: The number analyzed depends on the identification and recovery of relevant tissue type (benign, adjacent, tumor).

Compliance: Number of Participants Who Took Study Drug Per Protocol

Summarized by treatment arm with descriptive statistics, and tested for imbalance using Wilcoxon rank-sum test. Reported for each visit per protocol at Week 13, Week 26, Week 39, and Week 52 (end of study).

Time frame: Up to 1 year

Population: One participant has no compliance values for weeks 26 and 39.

Incidence of Adverse Events Graded Per Common Terminology Criteria for Adverse Events (CTCAE)

Patient toxicity throughout the study will be summarized in several ways; the presence or absence of any toxicity, worst CTCAE grade, and strongest investigator-defined relationship will all be examined and characterized by treatment arm, and analyzed appropriately (Wilcoxon rank-sum for ordinal data, Fisher's exact test for dichotomous data, and log rank test for time to event data).

Time frame: Up to 1 year

Prostate Specific Antigen Doubling Time (PSA DT)

PSA DT will be determined from PSA values obtained during study participation (baseline and weeks 13, 26, 39 and 52). The secondary endpoint of PSA DT is based on the value at study completion (week 52 or at point of early termination). However, PSA DT will be determined starting at week 26 (the earliest time point with 3 values) and week 39 and recorded. PSA doubling time is a measure based on the slope of the PSA at multiple time points. If the slope is relatively flat, the predicted doubling time could be far beyond the length of the actual study. As such, the value is not limited to the time frame over which data is collected from the participant.

Time frame: up to 52 Weeks

Population: One of the participant's PSA values were 'non-detectable', therefore PSA observations could not be calculated for that participant.
