About this study

Official title: A Phase I Prevention Trial of ACTIVIN Grape Seed Extract as an Aromatase Inhibitor In Healthy Postmenopausal Women at Risk for Breast Cancer

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of IH636 grape seed extract may prevent breast cancer.

PURPOSE: This phase I trial is studying the side effects and best dose of IH636 grape seed extract in preventing breast cancer in postmenopausal women at risk of developing breast cancer.

Read the detailed description

OBJECTIVES:

  • Determine the efficacy of IH636 grape seed proanthocyanidin extract, in terms of suppression of estrogen biosynthesis, in healthy post-menopausal women at high risk of developing breast cancer.
  • Determine the safety and tolerability of this dietary supplement, in terms of symptoms and changes in markers of bone and lipid metabolism and in markers of nonspecific adrenal suppression, in these participants.
  • Determine, preliminarily, an optimum biologic dose of this dietary supplement, as defined by suppression of serum estradiol, in these participants.
  • Determine a minimum duration of use of this dietary supplement to achieve aromatase inhibition in these participants.

OUTLINE: This is a pilot, dose-finding, placebo-controlled study.

Participants receive oral placebo once or twice daily on days -14 to 0. Participants then receive oral IH636 grape seed proanthocyanidin extract once or twice daily on days 1-85. Treatment continues in the absence of toxicity.

Cohorts of 6 participants receive one of four dose levels of IH636 grape seed proanthocyanidin extract up to an established safe dose.

PROJECTED ACCRUAL: A total of 24 participants will be accrued for this study within 12 months.

What is being measured

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

  1. Estrogen suppression as measured by serum estradiol, estrone, estrone sulfate, and sex hormone binding globulin

    Measured: at 1, 2, 4, 8, and 12 weeks

Secondary outcomes (5)
  1. Androgenic effects as measured by serum testosterone, androstenedione, dehydroepiandrosterone (DHEA), and dehydroepiandrosterone sulfate (DHEAS)

    Measured: at 1, 2, 4, 8, and 12 weeks

  2. Lipid effects as measured by total cholesterol, LDL, HDL, and triglycerides

    Measured: at 12 weeks

  3. Bone metabolic effects as measured by bone-specific alkaline phosphatase and N-telopeptides

    Measured: at 12 weeks

  4. Insulin regulatory effects as measured by insulin-like growth factor 1 (IGF1) and insulin-like growth factor-binding protein 3 (IGFBP3)

    Measured: at 12 weeks

  5. Pharmacokinetics as measured by procyanidins

    Measured: before and after first dose and then at 1, 2, 4, 8, and 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing IH636 grape seed proanthocyanidin extract in people with Breast Cancer, run by City of Hope Medical Center 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?

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: finished, as of the sponsor's last update on 8 Jun 2015. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Estrogen suppression as measured by serum estradiol, estrone, estrone sulfate, and sex hormone binding globulin (time frame: at 1, 2, 4, 8, and 12 weeks). 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 8 Jun 2015.
