Anastrozole and Letrozole
NCT00762294 · View on ClinicalTrials.gov ↗
Study Summary
Aromatase Inhibitors (AI) are effective for secondary prevention of breast cancer and may soon replace tamoxifen as first-line therapy in the treatment of hormone-sensitive breast cancer. However, because these medications produce a marked reduction in serum estrogen levels, this is likely to result in an increased rate of bone loss and risk of developing osteoporosis and fractures in postmenopausal women treated with these agents. Indeed, substantial bone loss has been reported in several large clinical trials of AIs. Osteoporosis drugs are available that could prevent this loss, but they have frequent side effects and are expensive. Thus, treating all women receiving AIs might not be the most appropriate and cost-effective approach. A better approach might be to select women at highest risk of bone loss and only treat them with antiresorptive agents. The proposed pilot study will evaluate women who receive anastrozole or letrozole therapy, are receiving adequate amounts of calcium and vitamin D and have baseline normal or moderately low bone mass in order to determine if early changes in bone turnover markers correlate with bone loss at one year. If data from this pilot protocol support our hypothesis, then we would propose a larger trial to confirm it. The ultimate aim is to predict which women are at higher risk of bone loss and therefore treat them earlier with bone-sparing agents, while those with lower risk could be monitored on conservative therapy.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00762294
The ClinicalTrials.gov registry entry for NCT00762294 describes a study currently listed as completed. It is categorized as an unspecified phase, 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 25 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is UConn Health, which has 176 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Breast Cancer appearing as the primary indexed condition, and to 0 interventions. 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: NCT00762294 reports 1 study location spanning 1 distinct geographic area — top geographies include Connecticut. 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.
