简要总结

This is a randomized, double-blinded, placebo-controlled dose-response efficacy study of oral (Z)-endoxifen in premenopausal women with measurable breast density. There will be 5 in-clinic visits (Screening, Day 1, Months 1, 3 and 6) and 3 self-report visits (Months 2, 4 and 5). Standard of care mammograms will be used for the screening mammogram as well as the 24-month follow up visit.

入选标准

  • Premenopausal women (defined as having at least one menstruation during the prior 12 months; women with an intrauterine device are considered premenopausal if <52 years)
  • Women of childbearing potential using a highly effective method of birth control* throughout the study period and willing to comply with monthly pregnancy testing
  • Screening mammogram performed within 3 month of study inclusion
  • Mammographic density assessed as BI-RADS® score B, C, or D
  • Must have given written informed consent before any study-related activities are carried out and must be able to understand the full nature and purpose of the trial, including possible risks and adverse effects

排除标准

  • Mammographic BI-RADS® malignancy code ≥3 at baseline mammography
  • Any previous diagnosis of breast cancer, including carcinoma in situ, or any other cancer (non-melanoma skin cancer and in situ cancer of the cervix are not exclusion criteria)
  • A history of breast surgery, e.g., reduction or enlargement, which might affect mammographic density measurements
  • Current medical conditions:
  • APC (activated protein C) resistance, an inherited coagulation disorder
  • Systolic pressure higher than 160 mm Hg or diastolic higher than 100 mm Hg
  • Cataract(s)
  • Uncontrolled diabetes (defined as HbA1c >50 mmol/mol)
  • Abnormal lab values deemed clinically significant by Investigator
  • Women who have an increased risk of venous thrombosis due to immobilization, e.g., using wheelchair
  • Agents that have the potential to decrease endoxifen levels through increased metabolic clearance:
  • Certain anti-epileptic therapies (carbamazepine, fenytoin, fenobarbital, lamotrigine)
  • Certain antibiotics (rifamycins)
  • St John's wort (in Swedish: johannesört)
  • Certain HIV medications (efavirenz, ritonavir)
  • Lactating, pregnant, or plan to become pregnant in the next year
  • History of thromboembolic disease such as embolus, deep vein thrombosis, stroke, TIA (transient ischemic attack) or myocardial infarction
  • Allergy to endoxifen or any of its components
  • Previous treatment with an anti-oestrogen, including experimental drug studies (e.g., Karma CREME, Karisma-1 or Karisma-2)
  • Prescribed and regular use of anticoagulants (defined as substances included in group B01A in the ATC-system)
  • Participation in another investigational clinical trial in the last 6 months
  • Not willing or able to understand the study information and/or informed consent
