About this study
Official title: Alendronate Prevents Microarchitectural Deterioration of Trabecular Bone in Early Postmenopausal
The purpose of this study is to evaluate the changes in bone structure as determined by magnetic resonance imaging measurements among early postmenopausal women after 24 months of treatment with alendronate, 70 mg once a week as compared to placebo
Read the detailed description
This is a randomized, double-blind, 24-month study. Fifty-five postmenopausal women, age range of 45-65 years, with low bone density will be recruited, with half of the subjects receiving alendronate + 2800 IU of vitamin D once weekly, the other half receiving placebo + 2800 IU of vitamin D once weekly. All study subjects will receive supplemental calcium 1000 mg/day + Vitamin D 400 IU/day. Measurements of microarchitecture will be made in the wrist, ankle, and hip, and the changes in trabecular bone will be assessed at 0, 12 and 24 months. Markers of bone turnover and bone mineral density (BMD) will be used to characterize the cohort and postmenopausal changes in bone turnover and density.

What is being measured
The primary outcome is the main question the study is designed to answer.
Mean % Change From Baseline in Trabecular Number (Tb.N) by HR-pQCT
Trabecular number is a three-dimensional measure of the mean inter-trabecular distance; the primary micro-architectural feature measured by high-resolution CT imaging. The parameter was calculated from scans of the distal radius and distal tibia at baseline, 12, and 24 months. The percent change from baseline over these time periods was calculated as the primary outcome measure indicating the micro-architectural status of trabecular bone.
Measured: Baseline, 24 months

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing alendronate sodium in people with Osteopenia and Osteoporosis, run by University of California, San Francisco 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 4 inclusion and 12 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 14 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 10 Aug 2011). 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?
Mean % Change From Baseline in Trabecular Number (Tb.N) by HR-pQCT (time frame: Baseline, 24 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 14 Aug 2013; AzTrials last refreshed its copy on 7 Nov 2026.
