IH636 Grape Seed Extract in Preventing Breast Cancer in Postmenopausal Women at Risk of Developing Breast Cancer
This study is currently recruiting participants.
Verified by National Cancer Institute (NCI), April 2007

Sponsor: Beckman Research Institute
Collaborator: National Cancer Institute (NCI)
Information provided by: National Cancer Institute (NCI)
ClinicalTrials.gov Identifier: NCT00100893
  Purpose

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.


Condition Intervention Phase
Breast Cancer
Dietary Supplement: IH636 grape seed proanthocyanidin extract
Phase I

Study Type: Interventional
Study Design: Prevention, Placebo Control
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

Primary Outcome Measures:
  • Estrogen suppression as measured by serum estradiol, estrone, estrone sulfate, and sex hormone binding globulin at 1, 2, 4, 8, and 12 weeks [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Androgenic effects as measured by serum testosterone, androstenedione, dehydroepiandrosterone (DHEA), and dehydroepiandrosterone sulfate (DHEAS) at 1, 2, 4, 8, and 12 weeks [ Designated as safety issue: No ]
  • Lipid effects as measured by total cholesterol, LDL, HDL, and triglycerides at 12 weeks [ Designated as safety issue: No ]
  • Bone metabolic effects as measured by bone-specific alkaline phosphatase and N-telopeptides at 12 weeks [ Designated as safety issue: No ]
  • Insulin regulatory effects as measured by insulin-like growth factor 1 (IGF1) and insulin-like growth factor-binding protein 3 (IGFBP3) at 12 weeks [ Designated as safety issue: No ]
  • Pharmacokinetics as measured by procyanidins before and after first dose and then at 1, 2, 4, 8, and 12 weeks [ Designated as safety issue: No ]

Estimated Enrollment: 24
Study Start Date: January 2005

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.
