Study Endpoints

Primary Endpoints

The primary objective of this study is to evaluate the safety of continued once-daily dosing with 100 mg ALX1-11 in postmenopausal osteoporotic women who participated in TOP and OLES clinical trials.
Throughout the study period of approximately 18 months.
To evaluate the safety of continued dosing with ALX1-11, up to a maximum of 24 months, in postmenopausal osteoporotic women who participated in Protocol ALX1-11-93001 (TOP).
24 months of treatment
Compare effects of 18 months of treatment with ALX1-11/placebo on the incidence of new and/or worsened thoracic and lumbar vertebral fractures in postmenopausal women with osteoporosis receiving calcium and vitamin D3 supplements
At Month 18
Efficacy was assessed as percent change from baseline in BMD, BMC, and BMA at the lumbar spine, total hip, femoral neck and whole body (excluding the head) using DXA.
12 months of treatment

Secondary Endpoints

The secondary objective is to evaluate the continued efficacy of once-daily treatment with ALX1-11 for maintaining increases in bone mineral density (BMD).
Throughout the study period of approximately 18 months.
To evaluate the continued efficacy of once-daily treatment with ALX1-11 for maintaining increases in BMD and other measures of bone quality and strength.
24 months of treatment
Incidences of vertebral fractures at Month 12; hip and wrist fractures; and other clinical fractures.
