Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • Men only
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Documented disease progression while on placebo in the GUP-0205-1 or GUP-0205-1XX study (a ≥100% increase over baseline serum PSA with a minimum increase of 1.0 ng/mL.
  • Willingness and ability to sign an informed consent document.
  • Agreement with complete abstinence from other commercially available pomegranate products during the course of the study.
  • Use of dietary/herbal supplements (e.g., saw palmetto, selenium, etc) are acceptable provided the dose has been stable for at least 2 months prior to screening and the subject agrees not to change/stop during the course of the study.
  • Performance status 0 or 1 on the ECOG scale at time of entry into this extension Study.

Who cannot join

  • Significant concomitant medical or psychiatric condition that, in the opinion of the investigator, would make the subject a poor protocol candidate.
  • Hormonal therapy, with the exception of neoadjuvant androgen deprivation therapy (ADT) prior to or concurrent with primary therapy. Subjects who underwent neoadjuvant ADT cannot have a serum testosterone of ≤150 ng/mL at study entry.
  • Concomitant or antecedent hormonal therapy for rising serum PSA after initial therapy of prostate cancer.
  • Subjects unable or unwilling to comply with protocol requirements.
  • Prior treatment with experimental drugs, high dose steroids, or with any other cancer treatment within 4 weeks prior to the first dose of study product and for the duration of the study.
  • Serum PSA >7.0 ng/mL (assessed at termination of the double-blind study or ET of the double-blind extension GUP-0205-1XX); at any PSA level, the subject will be excluded if determined by the investigator that the subject's continued participation would not be in their best interest).

  • Serum PSA doubling time <13 weeks (assessed at termination of the double-blind study or ET of the double-blind extension GUP-0205-1XX)).
  • Evidence of metastatic disease on physical examination or on CT or bone scan.
  • Use of finasteride, dutasteride at any point since primary therapy or during the study.
  • Clinically significant abnormal laboratory value greater than 2 times the upper limit of normal (>2XULN).

About this study

Official title: An Open-label Extension Study of the Effects of Pomegranate Extract on Rising Prostate-specific Antigen Levels in Men Following Primary Therapy for Prostate Cancer.

This study is an open-label extension to the double-blind GUP-0205-1 and double-blind extension GUP-0205-1XX studies. High concentrations of anti-oxidants in pomegranate seeds present a potential strategy to delay clinical prostate cancer progression and prolong the interval from treatment failure to hormonal ablation. Eligible male subjects were previously assigned to the placebo group in the double-blind core study or the double-blind extension study and were diagnosed with disease progression while on placebo treatment. Upon satisfying all entry criteria, the subjects will receive open-label pomegranate extract for up to 48 months in the absence of further disease progression or intolerable toxicity.

Read the detailed description

This study is an open-label extension to the double-blind GUP-0205-1 and double-blind extension GUP-0205-1XX studies. Eligible male subjects, i.e.,men who had rising PSA levels following primary therapy for localized prostate cancer, were previously assigned to the placebo group in the double-blind study or the double-blind extension and were diagnosed with disease progression while on placebo treatment. Upon satisfying all entry criteria, the subjects will receive open-label pomegranate extract for up to 48 months in the absence of further disease progression or intolerable toxicity.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The within-subject difference between the PSA doubling time from the end of double-blind placebo treatment to the end of open-label pomegranate extract treatment.

    Measured: 12 months

Secondary outcomes (1)
  1. The effect of treatments on response rates for positive PSA doubling times (greater than 150% baseline), and for negative post-treatment PSA doubling time (i.e., declining PSA), and for changes in absolute PSA values.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing pomegranate liquid extract in people with Prostate Cancer, run by Roll International Corporation at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 16 Mar 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The within-subject difference between the PSA doubling time from the end of double-blind placebo treatment to the end of open-label pomegranate extract treatment. (time frame: 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2012.
