Vitamin D, Diet and Activity Study
A study testing Vitamin D in people with Breast Cancer and Obesity, run by Fred Hutchinson Cancer Center at 1 site in United States.
Trial summary
Experimental and human data suggests that vitamin D could protect against breast cancer. Overweight/obese individuals are at increased risk of low vitamin D levels. Vitamin D may reduce production of fat tissue, thereby reducing weight gain, which would result in lower levels of adipose-derived hormones and other… Read more about this study

About this study
Official title: Vitamin D, Weight Loss, and Breast Cancer Biomarkers
Experimental and human data suggests that vitamin D could protect against breast cancer. Overweight/obese individuals are at increased risk of low vitamin D levels. Vitamin D may reduce production of fat tissue, thereby reducing weight gain, which would result in lower levels of adipose-derived hormones and other breast cancer risk factors.The purpose of this study is to test the effect of vitamin D supplementation on the response to a weight loss (diet + exercise) intervention and select breast cancer risk factors in overweight and obese postmenopausal women with low blood vitamin D levels.
Read the detailed description
Objective: To test the incremental effect of vitamin D supplementation (2000 IU/day) in 228 overweight and obese postmenopausal women with low blood vitamin D levels on response to a weight loss (diet + exercise) intervention in a double-blind placebo-controlled clinical trial.
Primary Aim:
- Determine the effects of 12-months vitamin D supplementation vs. placebo on weight loss in women following a weight loss diet and exercise program.
Secondary Aims:
- Determine the effects of 12-months vitamin D vs. placebo on blood biomarkers associated with increased breast cancer risk (insulin, glucose, CRP).
- Test 12-months vitamin D effects on muscle strength as measured by 1RM leg press and bench press in women undergoing weight loss.
- Test the effect of 12-month vitamin D supplementation on effects on quality of life (QOL) in women undergoing weight loss.
Additional Aims:
- In a 50% subset of women, test the effect of 12-month vitamin D supplementation vs. placebo on breast epithelial cell cytomorphology (quantified by the Masood cytology index) obtained through random periareolar fine needle aspiration (RPFNA).
- Collect subcutaneous abdominal fat aspirations in the 50% subsample of women.
OUTLINE: This is a randomized study. Participants are stratified according to body mass index (< 30 vs ≥ 30) and RPFNA-consent. All participants will receive a 6-month weight loss intervention (prescribed weight loss goal of 10% of initial body weight) followed by 6 months' maintenance therapy.
Baseline, 6-, and 12-month measurements will include weight, BMI, waist and hip circumference, serum 25-hydroxyvitamin D, fasting blood samples, and questionnaires on details of diet especially items containing vitamin D, physical activity levels, sun exposure including clothing and sunscreen habits, dietary supplement and vitamin use, and medications.

Questions about this trial
What is this clinical trial studying?
A study testing Vitamin D in people with Breast Cancer and Obesity, run by Fred Hutchinson Cancer Center 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 8 inclusion and 18 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 7 Aug 2013. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Compare the effects of a 1-year one year Vitamin D supplementation vs placebo, on weight loss in postmenopausal women following a weight loss diet and exercise program. (time frame: One Year). 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 NCT01240213, which also lists 4 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 7 Aug 2013.
