Outcome results

Primary

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

Population: Full Analysis Set (FAS) consisted of participants who received \>=1 dose of study drug; had \>=1 post-baseline observation for the analysis endpoint; and had baseline data. For analysis, participants in the FAS were categorized into 3 subgroups by osteoporosis therapy received at baseline: Recent/Current, Other therapy, and Treatment Naïve

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

Population: Per Protocol Population consisted of FAS but excluded participants who had important deviations from protocol or did not complete study on study drug. For analysis, participants in Per Protocol Population were categorized into 3 subgroups by osteoporosis therapy received at baseline: Recent/Current, Other therapy, and Treatment Naïve.
