Inclusion Criteria

4.1.1 Ambulatory postmenopausal women, age = 55 to = 90 years at randomization. Postmenopausal status is defined as no vaginal bleeding or spotting for 12 consecutive months prior to screening.
4.1.2 Subject meets at least one of the following BMD and fracture criteria
BMD T-score = -2.50 at the total hip or femoral neck AND EITHER at least one moderate (SQ2) or severe (SQ3) vertebral
fracture OR at least 2 mild (SQ1) vertebral fractures
or
BMD T-score = -2.00 at the total hip or femoral neck AND EITHER at least 2 moderate (SQ2) or severe (SQ3) vertebral fractures OR a fracture of the proximal femur that occurred within 3 to 24 months prior to randomization
BMD T-scores at the time of screening will be assessed by the central imaging vendor based on DXA scans and using data for Caucasian women from the National Health and Nutritional Examination Survey (NHANES) 1998.
Vertebral fractures at the time of screening will be assessed by the
central imaging vendor based on lateral spine x-rays.
History of proximal femur fracture will be assessed by the principal
investigator based on discharge summary, radiology report, or
comparable documentation of type and date of fracture.
4.1.3 At least one hip is evaluable by DXA, as assessed by the principal investigator
4.1.4 Subject has provided informed consent
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 150
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 3850

-more than 1 dose received within 5 years prior to randomization
-IV ibandronate or IV pamidronate:
-any dose received within 12 months prior to randomization

-History of metabolic or bone disease (except osteoporosis) that may interfere with the interpretation of the results, such as sclerosteosis, Paget’s disease, osteomalacia, osteogenesis imperfecta, osteopetrosis, ankylosing spondylitis, Cushing’s disease, hyperprolactinemia, and malabsorption syndrome
-History of solid organ or bone marrow transplants
-Vitamin D insufficiency, vitamin D levels < 20 ng/mL as assessed by the central laboratory.
-Current hyper- or hypocalcemia, defined as albumin-adjusted serum calcium outside the normal range, as assessed by the central laboratory. Serum calcium levels may be retested once in case of an elevated serum calcium level within 1.1x the upper limit of normal as assessed by the central laboratory.
-Current, uncontrolled hyper- or hypothyroidism, defined as thyroidstimulating hormone outside of the normal range, per subject report or chart review
-Current, uncontrolled hyper- or hypoparathyroidism, defined as PTH outside the normal range, per subject report or chart review
-Possible diagnosis of multiple myeloma or related lymphoproliferative disorder, as assessed by serum protein electrophoresis performed by the local laboratory
-Exclusion criteria related to contraindications or possible signs of intolerance to ALN; contraindications and potential signs of intolerance for ALN therapy include:
•Hypocalcemia
• Abnormalities of the esophagus, which delay esophageal emptying such as stricture or achalasia
• Inability to stand or sit upright for at least 30 minutes
• Hypersensitivity to ALN or other constituents of ALN tablets
• Pregnancy and lactation

-General
• Subject is currently enrolled in another investigational device or drug study, or less than 30 days since ending another investigational device or drug study(s), or re
