What researchers measure

Primary outcomes

  1. Number of Participants With Serum 25-hydroxyvitamin D >=50 ng/mL at Week 26

    Serum samples to measure serum 25-hydroxyvitamin D \[25(OH)D\] will be collected at specific visits during the treatment phase of the study.

    Time frame: Week 26

Secondary outcomes

  1. Mean Percent Change From Baseline of Bone Resorption Marker of Serum Beta-CrossLaps at Week 26

    Serum samples for Beta-CrossLaps (β-CTx) will be collected at specific visits during the treatment phase of the study.

    Time frame: Baseline and Week 26

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2011 to primary completion in Dec 2012, 13 months.

Results were first posted in Jan 2014, 1 year 1 month after primary completion.

Of 49 industry-sponsored phase 3 interventional studies under Osteoporosis, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 43. This study's 13 months is below that.

Counting every sponsor, half of 58 studies reached it within 26 months; a quarter within 19 and three quarters within 44.

How these figures are worked out, and which studies are left out of them.

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 Apr 22, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
