A Study of Bonviva (Ibandronate) Once Monthly in Post-Menopausal Women With Osteopenia

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)

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.

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.

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.

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.

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.

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].
