Study summary

High bone turnover with the bone resorption exceeding bone formation is a major mechanism of postmenopausal osteoporosis. Therefore, inhibition of bone resorption is a rational approach for the prevention. The Objective of the current study was to determine the short-term efficacy of once-weekly low dose alendronate in the prevention of bone loss in early postmenopausal Korean women with moderate bone loss via bone turnover markers.

This study was a 12-week, randomized, double-blind clinical trial compared the effects of placebo with alendronate 20 mg once weekly. All subjects received supplemental calcium 600 mg and vitamin D 400 IU daily. Fifty two postmenopausal women (the ages between 50-65 year) with lumbar spine BMD at least 2.0 SD below the peak young adult mean were recruited at Eulji University Hospital, Daejeon, Korea. BMD was measured by DXA at baseline and serum alkaline phosphatase, osteocalcin and C-terminal telopeptide of type I collagen was measured at baseline and 12 weeks after treatment.

  • Placebo comparator
    Alendronate, Placebo

    All subjects were given 600 mg of calcium and 400 IU of vitamin D supplements. The subjects were randomized to receive weekly alendronate 20 mg (n = 31) or placebo (n = 32).

    Drug: Alendronate

Interventions

  • DrugAlendronate

    Take two tablets (alendronate 10 mg) once weekly with a full glass of plain water in the morning after an overnight fast and to refrain from lying down or taking any other beverage or food for at least 1 h thereafter

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 5, 2014, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
