Vitamin D and Physical Activity on Bone Health
United States191 participantsStarted 2011-08
Plain-language summary
This research will examine the effectiveness of vitamin D or placebo (the placebo is a tablet that looks like Vitamin D study drug, but has no Vitamin D study drug in it), with and without physical activity (walking and progressive resistance exercise), in treating bone loss in women who have undergone treatment for breast cancer. The investigators would also like to find out if the physical activity program improves cardiovascular fitness, energy expenditure, muscular strength, muscle mass, and balance. One hundred five (105) subjects are expected to take part in this study. The investigators don't know if bone loss in breast cancer survivors should be treated differently than bone loss in other women.

Inclusion Criteria:
* Must be female and have a primary diagnosis of Stage I, II, or III hormone-receptor positive breast cancer.
* Women must be postmenopausal at time of enrollment.
* Must provide informed consent.
* Must be willing to discontinue use of calcium and/or vitamin D supplements.
* Participants must have an ionized serum calcium level within normal limits (1.19-1.29mmol/L) and a total corrected serum calcium of \< 10.6 mg/dl.
* Participants must be slightly vitamin D deficient (serum vitamin D level \<32ng/ml)
* Must have a functional capacity rating of ≤ 2 on the Eastern Cooperative Oncology Group (ECOG) performance status when assessed at baseline.132
* Must have the approval of their treating physician (or physician's nurse practitioner or physician's assistant) to participate in sub-maximal physiological fitness testing and a low to moderate home-based walking and progressive resistance exercise program and to receive the 24-week supplementation of vitamin D.
* Must be less than five years from the diagnosis of breast cancer and must be within 12 months of starting treatment with aromatase inhibitors (AI) in accordance with American Society of Clinical Oncology (ASCO) guidelines.
Exclusion Criteria:
* Subjects with life-threatening conditions that would preclude them from breast cancer treatment including chronic cardiac failure, which is unstable despite medication use, uncontrolled hypertension, uncontrolled diabetes mellitus, or unstable coronary arter…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Measure the amount of bone loss in non-metastatic breast cancer patients receiving a high dose vitamin D therapy along with a structured home-based walking and progressive resistance exercise program.
