Postmenopausal Osteoporosis
Conditions
Brief summary
The aim of the study is to assess the effect of an antiresorptive medication in combination with standard dose or alternate dose teriparatide. The study extension will evaluate the effect of one-dose of zoledronic acid after the teriparatide/denosumab combination.
Interventions
denosumab subcutaneous injection
teriparatide daily subcutaneous injection
zoledronic acid infusion
