About this trial

The aim of this study is to investigate the effect of romosozumab on bone cells during early and late phases of treatment.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Female aged > 45 years

> 36 since last spontaneous menses

> 36 months since hysterectomy, plus serum FSH > 40 units / liter if < 60 years

Disqualifiers

renal disease (stage 4 CKD)

elevated blood PTH (intact PTH > 77 pg/ml).

serum 25-OH vitamin D < 20 ng/ml

major psychiatric disease that in the opinion of the investigator would preclude the subject from providing adequate informed consent or completing the protocol procedures.

Trial outcomes

Primary outcomes

1

Osteoblast progenitor cell numbers

The investigators are testing the mechanistic hypothesis that romosozumab treatment increases osteoblast progenitor cell numbers at early, but not late, treatment time points.

Time frame
3-6 weeks (early) versus 6-8 months (late)
