Trial Information

A Clinical Trial to Assess the Efficacy of a Supplemental Formula Targeting Breast Health in Beneficially Altering Urinary Estrogen Metabolites Levels in Both Pre- and Post-menopausal Women


The active botanical constituents in femMED Breast Health Formula contain lignans, compounds
with anti-estrogenic activity, that have been shown to exert an estrogenic effect during the
follicular phase [i.e. when estrogen is low] and an antiestrogenic effect in the luteal
phase of a female menstrual cycle. These are plant-derived chemicals that can act as weak
mimics of estrogen in the body. Overall these compounds have been found to be helpful in
stabilizing the natural cyclical fluctuation of estrogen levels.

The trial will be a double-blind, placebo-controlled parallel study in which 100 subjects
will be recruited to one of two arms of the study: one arm will consist of pre-menopausal
women; another will consist of post-menopausal women. Each arm of the study will be carried
out concurrently and in one phase, with no washout period. The placebo assignment will be
randomized within each arm of the study.

Subjects in each arm of the study will follow the same protocol. Urine and blood samples
will be collected from each group at both the first and last visit, and subjects will
receive a month's supply of treatment or placebo at the first visit, which they will consume
on a daily basis until their second lab visit 28 days later. Urine samples will be analyzed
for the following estrogen metabolites: 2-OH-estrone and 16-α OH-estrone. Blood samples
would be collected and assessed for levels of enterolactone. Pre and post-supplementation
results will be assesses for any differences by statistical comparison.


Inclusion Criteria:



- 18 years of age or older

- Healthy

- Willing to collect urine samples and to have blood drawn

- Post-menopausal and have not taken hormone replacement therapy (HRT) in the past year
(48 subjects)

- Pre-menopausal (48 subjects)

Exclusion Criteria:

- Diagnosed with any major illness(e.g. cancer)

- Diabetes, thyroid disease, atypical hyperplasia, fibrocystic breast disease, family
history of ovarian cancer, a history of "migraines with aura"

- Women taking blood thinner or thyroid medication (including warfarin)

- Known allergy to any of the any of the study ingredients

- Pregnancy or lactation

- Regular consumption in the previous 3 months of any other natural health products
(NHPs) or pharmaceutical containing ingredients with a similar effect on estrogen
metabolism as those included in the femMED Breast Health treatment

- Family history of breast cancer risk

- Post-menopausal women on HRT

- Pre-menopausal women taking hormonal contraceptives (oral contraceptives, the patch
etc.)

- All other forms of estrogen, progesterone and/or androgens (i.e. testosterone
therapy)

Type of Study:

Interventional

Study Design:

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Prevention

Outcome Measure:

2-OH Hydroxy Estrone: 16-alpha-OH Estrone

Outcome Description:

2-OHE:16α-OHE1 (2:16 ratio) - 2:16 ratios less than 2.0 indicate increasing long-term risk for breast, cervical, and other estrogen sensitive cancers. Urine samples will be analyzed for the following estrogen metabolites: 2-OH-estrone and 16-α OH-estrone.

Outcome Time Frame:

Day 0, Day 28

Safety Issue:

No
