Primary Outcome(s)

Primary end point(s): During the overall study period (12-month double-blind ALN-controlled study period followed by the open label ALN study period)
• Subject incidence of clinical fracture (nonvertebral fracture and clinical vertebral fracture) at primary analysis
• Subject incidence of new vertebral fracture through Month 24

Main Objective: For the overall study period (12-month double-blind alendronate [ALN]-controlled study period

• To assess the effect of AMG 785 treatment for 12 months followed by ALN treatment compared with ALN treatment alone on the subject incidence of new vertebral fracture in women with PMO

Secondary Objective: To assess the effect of AMG 785 treatment for 12 months followed by ALN treatment compared with ALN treatment alone on:
• Subject incidence of fractures (all fractures [nonvertebral fractures and new vertebral fractures], new or worsening vertebral fracture, nonvertebral fracture, major nonvertebral fracture [pelvis, distal femur, proximal tibia, ribs, proximal humerus, forearm, and hip], hip fracture, and multiple new or worsening vertebral fracture)
• Percent changes in Dual energy X-ray Absorptiometry (DXA) bone mineral density (BMD) at the lumbar spine, total hip, and femoral neck
To assess the effect of AMG 785 treatment for 12 months compared with ALN treatment on:
• Subject incidence of fractures (clinical fracture [nonvertebral fracture and clinical vertebral fracture], new vertebral fracture, all fractures [nonvertebral fractures and new vertebral fractures])
