About this study
Official title: An Exploratory Pilot Study of Vitamin D Supplementation in Women With DCIS and/or LCIS
The purpose of this study is to determine the safety and usefulness of oral Vitamin D supplementation in subjects with in situ carcinoma. More specifically, this study is being done to (1) understand the effect of Vitamin D supplementation on behavior of breast cancer cells and (2) the development of invasive breast cancer disease.
Read the detailed description
In vitro, calcitriol, the most potent metabolite of vitamin D, inhibits a variety of cellular pathways that promote cell proliferation and survival. Vitamin D has been shown to reduce the growth of breast cancer precursor cells in cell culture studies. In animal models Vitamin D has been shown to prevent the growth and progression of transplanted cell lines MCF710A, which is a model of pre-invasive cancer. Serum Vitamin D level deficiency correlates with an increased risk of breast cancer, and reduced survival of breast cancer patients. Vitamin D is also recognized to have effects on immune cell function and autoimmunity. The safety profile of oral Vitamin D, and its metabolite calcitriol, was well established for moderate term and acute therapy worldwide. Potential additional primary and secondary benefits of vitamin D are a) the suppression of carcinogen-induced transformation or progression of breast epithelium, and b) the enhancement of innate immune defense of pre-invasive breast cancer lesions, and c) its qualification as a combination therapy when combined with other neoadjuvant therapies for DCIS.
Patients who have been diagnosed by core biopsy with carcinoma in situ, ductal or lobular, will be evaluated for vitamin d supplementation. Patients with vitamin d levels less than 50 will be eligible for participation. They will receive a one month (30 days) schedule of vitamin D supplementation and then proceed with the standard of care of surgical excision. Immunohistochemistry studies will be performed on the diagnostic core biopsy and the surgical specimen to evaluate the impact of vitamin d supplementation on: the proliferative index-ki67, proliferative marker- PCNA, proteins of the autophagy pathway (LC3B, ATG7), her2 localization, and levels of PMCA2 - calcium efflux channel.

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 100,000 IU followed by 4000 IU orally once daily for 30 days.
| Study group | Role | What they receive |
|---|---|---|
| Vitamin D3 | Experimental | Patients will be dispensed cholecalciferol, 32 capsules/bottle of 1cap/4000 IU PO QD on Day 1 visit to take home. Bottle must be labeled with instructions on how to take the drug and the assigned patient ID number. Patients will be instructed to take 1 capsule per day, with water, for 29 days using the dispensed study bottle. They will be instructed to stop taking their daily vitamin D3 dose after 30 days of treatment. A study drug diary will be provided at Day 1 visit and patients will be instructed to complete the study drug diary daily from Day 2 to Day 30. Patient's report of vitamin-D3 intake from the diary must be reconciled against the number of capsules returned at Day 30 visit. Receives: Drug: Cholecalciferol |
What is being measured
The primary outcome is the main question the study is designed to answer.
Ki 67 Measured
The proliferation index measured by Ki67 will be described for both baseline (pre) and surgical (post) vitamin D supplementation. A paired t-test or the non-parametric Wilcoxon signed-rank test will be used when appropriate to compare patients' outcome between baseline and after-treatment.
Measured: 28 days +/- 3 days from Day 1 of treatment
Secondary outcomes (4)
Levels of Proteins of the Autophagy Pathway, LC3B
Descriptive statistics (N, mean, median, Min, Max, STD for continuous variables, and N, proportion for categorical variables) will be used to summarize patients' demographics as well as lab results. . A paired t-test or the non-parametric Wilcoxon signed-rank test will be used when appropriate to compare patients' outcome between baseline and after-treatment. A p-value of <0.05 will be considered statistically significant.
Measured: 28 days +/- 3 days from Day 1 of treatment
Levels of Proteins of the Autophagy Pathway, ATG7
Descriptive statistics (N, mean, median, Min, Max, STD for continuous variables, and N, proportion for categorical variables) will be used to summarize patients' demographics as well as lab results. . A paired t-test or the non-parametric Wilcoxon signed-rank test will be used when appropriate to compare patients' outcome between baseline and after-treatment. A p-value of <0.05 will be considered statistically significant.
Measured: 28 days +/- 3 days from Day 1 of treatment

A p-value of <0.05 will be considered statistically significant.
Measured: 28 days +/- 3 days from Day 1 of treatment

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Cholecalciferol in people with Breast Cancer, run by Inova Health Care Services 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 10 inclusion and 9 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: stopped early, as of the sponsor's last update on 16 Dec 2020. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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 16 Dec 2020). 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?
Ki 67 Measured (time frame: 28 days +/- 3 days from Day 1 of treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02936999, which also lists 32 linked publications.
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 16 Dec 2020.
