Design outcomes

Primary

MeasureTime frame
Main Objective: Evaluation of treatment efficacy by comparing the percentage change in bone density and selected parameters of bone quality and bone metabolism from the "Screening" day to the "End of Study" day between two groups of patients (with or without vitamin K2 supplementation);Secondary Objective: • Comparison of the percentage change of selected new markers of bone turnover (sclerostin, DKK-1) and sarcopenia parameters from the day of "Screening" to the day of "End of Study" between two groups of patients (with or without vitamin K2 supplementation) • Comparison of frequency and type of adverse reactions (tolerability), aortic calcifications (safety) and clinical fractures between two groups of patients • Comparison of adherence to therapy between two groups of patients;Primary end point(s): Stabilized bone density;Timepoint(s) of evaluation of this end point: 52 weeks

Secondary

MeasureTime frame
Secondary end point(s): Preventing the formation of vertebral body fractures;Timepoint(s) of evaluation of this end point: 52 weeks
