Outcome Measures

Primary Outcomes (1)

  • Change in Percent of Breast Epithelial Cells With Ki-67 Immunocytochemical Expression

    Change over the course of study in the percent of breast epithelial cells expressing the proliferation marker Ki- 67/MIB-1 in hyperplastic benign breast tissue acquired by random periareolar fine needle aspiration pre-study and post-study.

    12 months

Secondary Outcomes (2)

  • Change in Gene Expression

    12 months

  • Breast Cancer Prevention Trial (BCPT) Symptom Checklist

    12 months

Study Arms (2)

flaxseed lignan, SDG

EXPERIMENTAL

Secoisolariciresinol diglycoside

Drug: secoisolariciresinol

Placebo

PLACEBO COMPARATOR

Matched Placebo

Drug: Placebo

Interventions

The placebo contains same filler materials as commercially available Brevail® but without active SDG.

Placebo

1 capsule daily of secoisolariciresinol diglycoside (SDG)50mg

Also known as: SDG
flaxseed lignan, SDG

Eligibility Criteria

Age21 Years - 49 Years
Sexfemale
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may not qualify if:

  • Candidates are ineligible for tissue screening if they meet any of the following conditions:
  • Consumption of systemic antibiotics during the 3 weeks prior to baseline RPFNA. Systemic antibiotics reduce intestinal bacteria and thus the ability to convert SECO to ENL.
  • Consumption of supplements containing SDG (flaxseed or sesame seed) during the 3 weeks prior to baseline RPFNA. ( Consumption of foods containing flaxseed or sesame seed are OK.)
  • Use of any selective estrogen receptor modulator or aromatase inhibitor (tamoxifen, raloxifene, arzoxifene, acolbifene, anastrozole, exemestane, letrozole) within the previous 6 months.
  • Currently enrolled on an interventional investigational study.
  • Bilateral breast implants.
  • Invasive breast cancer or other invasive cancer diagnosis within five years.
  • Metastatic malignancy of any kind.excluding Hodgkin's or non-Hodgkin's lymphoma.
  • Current anticoagulant use.
  • Consumption of coumadin, fish oil, or other anticoagulants during the 3 weeks prior to baseline RPFNA.
  • Any other condition or intercurrent illness that in the opinion of the investigator makes the subject a poor candidate for RPFNA or the trial.
  • RPFNA performed in the follicular portion (day 1-10) of the menstrual cycle. Note that day 1 is defined as the first day of bleeding.
  • RPFNA specimen exhibits hyperplasia +/- atypia (Masood score of ≥13) with ≥500 cells on the cytology slide.
  • Ki-67 ≥2% positivity (≥500 cells).
  • Willing to continue without oral contraceptives throughout the duration of the study participation (12 months). Non-oral contraceptives are permissible. If heterosexually active, must be agreeable to use some non-hormonal form of contraception during the trial or husband or partner must have had a vasectomy. (Safety of SDG during pregnancy has not been documented).
