Clinical Trial Summary

This 2 arm study will evaluate the efficacy and safety of oral Bonviva 150mg once monthly compared with placebo in post-menopausal women with osteopenia. Patients will be randomized to receive either Bonviva 150mg po monthly, or placebo monthly. The anticipated time on study treatment is 1-2 years, and the target sample size is 100-500 individuals.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Relative Change From Baseline in Mean Bone Mineral Density (BMD) of the Lumbar Spine (L2 to L4) at Month 12	BMD was measured by a single dual-energy x-ray absorptiometry (DEXA) scan of the lumbar spine at the time of screening and at Month 12. A BMD measurement was considered unsuitable in case of detection of a fracture, an osteoarthritic process, or a scanning artifact that could not be removed to such a degree that accurate measurement of BMD would be considered jeopardized by the central reading center. The change in BMD was defined as the relative difference between the last individual measurement available at 12 months and Baseline, using the following formula: Relative change = 100 x (BMD at 1 year - BMD at baseline) / (BMD at baseline)	Baseline and Month 12	No
Secondary	Absolute Change From Baseline in Mean Lumbar Spine BMD at Month 12	BMD was measured by a single dual-energy x-ray absorptiometry (DEXA) scan of the lumbar spine at the time of screening and at Month 12. A BMD measurement was considered unsuitable in case of detection of a fracture, an osteoarthritic process, or a scanning artifact that could not be removed to such a degree that accurate measurement of BMD would be considered jeopardized by the central reading center. The absolute change from Baseline in mean BMD of the lumbar spine (L2-L4) was measured as g/cm^2 and summarized using descriptive statistics.	Baseline and Month 12	No
Secondary	Relative Change From Baseline in Mean Proximal Femur BMD at Month 12	BMD was measured by a single DEXA scan of the proximal femur at the time of screening and at Month 12. The relative (%) change from Baseline in BMD of the proximal femur (total hip, trochanter, femoral neck) at Month 12 was summarized using descriptive statistics. BMD of fractured bones that could impact the scan area were not taken into account.	Baseline and Month 12	No
Secondary	Absolute Change From Baseline in BMD of the Proximal Femur at Month 12	BMD was measured by a single DEXA scan of the proximal femur at the time of screening and at Month 12. The absolute change from baseline in BMD of the proximal femur (total hip, trochanter, femoral neck) at Month 12 was summarized using descriptive statistics. BMD of fractured bones that could impact the scan area were not taken into account.	Baseline and Month 12	No
Secondary	Relative Change From Baseline in Serum C-telopeptide Crosslinks of Type 1 Collagen (CTX)	Fasting blood samples were collected from participants for analysis of serum CTX (sCTX), which is a biochemical marker of bone resorption. Relative change from baseline of sCTX after 3, 6, and 12 months of treatment was summarized using descriptive statistics.	Baseline and 3, 6 and 12 months	No
Secondary	Absolute Change From Baseline in sCTX	Fasting blood samples were collected from participants for analysis of sCTX, which is a biochemical marker of bone resorption. Absolute change from baseline of sCTX after 3, 6, and 12 months of treatment was summarized using descriptive statistics.	Baseline and 3, 6, 12 months	No
Secondary	Percentage of Responders	Percent responders were defined as follows: Participants with a) lumbar spine (LS) BMD, equal to or above Baseline at Month 12 b) proximal femur BMD, equal to or above Baseline at Month 12 c) Both lumbar spine and proximal femur BMD, equal or above Baseline at Month 12. BMD of the lumbar spine was defined as the BMD of at least two vertebrae (L2-L4) that were not fractured and not affected by an osteoarthritic process, or a scanning artifact that could not be removed to such a degree that accurate measurement of BMD would be considered jeopardized by the central reading center. Proximal femur included total hip, trochanter and femoral neck sites.	Up to 12 months	No
Secondary	Number of Participants With Any Adverse Events (AEs) and Serious Adverse Events (SAEs)	An AE is any untoward medical occurrence in a participant who is administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. A serious adverse event is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect.	Up to 15 days after end of study treatment (Approximately 2 years)	No
Secondary	Number of Participants With Marked Laboratory Abnormalities	Blood for laboratory tests was taken at screening and immediately before participants received their monthly study medication at months 3, 6, and 12. The laboratory tests included: Hematology [white blood cells (WBCs), platelets, hematocrit, and hemoglobin] and Chemistry [albumin, creatinine, blood urea nitrogen (BUN), alanine aminotransferase (ALT), total calcium, 25-hydroxy vitamin D, phosphate, magnesium, sodium, potassium, and chloride].	Screening up to 12 months	No
