About this study
Official title: Effects of High-Dose Vitamin D on Circulating Vitamin D Levels and Breast Density in Postmenopausal Women at High Risk for Breast Cancer Development
This is a phase II study which will enroll 20 postmenopausal women who are at high risk for breast cancer development. The goal is to determine whether a one-year intervention of high-dose vitamin D at 2 different doses (20,000 IU weekly or 30,000 IU weekly) will increase circulating blood levels of vitamin D and to obtain preliminary data on the biologic effects of vitamin D for breast cancer prevention.
Read the detailed description
Participants will receive oral vitamin D3, cholecalciferol 20,000 IU or 30,000 IU weekly. Before beginning the intervention, the participants will have a general physical exam including a clinical breast exam and anthropometric measures, a morning blood draw (for analysis of 25(OH)D, 1,25(OH)D, parathyroid hormone (PTH), insulin-like growth factor (IGF)-I, insulin-like growth factor-binding protein 3 (IGFBP-3), estradiol, estrone, testosterone, and sex hormone-binding globulin (SHBG) at baseline, 6 months, and 12 months) and a bilateral mammogram (at baseline and 12 months). Participants will also complete a baseline questionnaire, collecting data on demographic information and breast cancer risk factors. In addition, we will be collecting data on vitamin D sources from diet and sunlight exposure using a validated questionnaire administered at baseline and 12 months.
For follow-up visits, the participant will be seen at the study site at months 3, 6, 9, and 12. During these visits, drug will be dispensed, adherence ascertained, and adverse events will also be assessed. In addition, blood (serum calcium, albumin, creatinine) and urine (urine calcium, creatinine) will be collected to monitor for toxicity. A 24-hour urine collection will be conducted at baseline and 12 months to assess for hypercalciuria. After the 1 year intervention, all participants will have a complete physical exam including clinical breast exam, a bilateral mammogram, blood draw, and complete a follow-up questionnaire.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CholecalciferolDrug
Also called Vitamin D3
Cholecalciferol is a vitamin D3. Vitamin D is important for the absorption of calcium from the stomach and for the functioning of calcium in the body. Cholecalciferol is used to treat or prevent many conditions caused by a lack of vitamin D.
Cholecalciferol will be available in gel capsule form at 10,000 IU (0.25 mg cholecalciferol) each.
Placebo capsuleDrug
Also called Placebo
Matching placebo capsules
| Study group | Role | What they receive |
|---|---|---|

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Cholecalciferol in people with Breast Cancer, run by Columbia University 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?
The sponsor lists 12 inclusion and 5 exclusion criteria. 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 27 Sep 2017. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 27 Sep 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Change in Serum 25(OH)D (time frame: Baseline to 1 year). 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 27 Sep 2017.
