Vitamin D and Physical Activity on Bone Health
NCT01419730 · View on ClinicalTrials.gov ↗
Study 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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01419730
The ClinicalTrials.gov registry entry for NCT01419730 describes a study currently listed as active not recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 191 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Rochester, which has 437 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Physical Fitness appearing as the primary indexed condition, and to 2 interventions — of which Physical Activity is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01419730 reports 1 study location spanning 1 distinct geographic area — top geographies include New York. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
