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 BDM 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) verterbral fracture OR at least 2 mild (SQ1) vertebral fractures
or
BDM T-score = -2.00 at the total hip r femoral nec AND EITHER at least 2 moderate (SQ2) or severe (SQ3) vertebral fractures OR a fracture of the proximal femur that occured within 3 to 24 months prior to randomization
BDM T-score 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 discharged 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

Exclusion Criteria

Strontium ranelate,or fluoride (for osteoporosis): more than 1 month of cumulative use within 5 years prior to randomization
IV bisphosphonates
•Zoledronic acid:-any dose received within 3 years prior to randomization-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-more than 3 years of cumulative use, unless last dose received = 5 years prior to randomization
Oral bisphosphonates:•More than 3 years of cumulative use, unless last dose received = 5
years prior to randomization•Any dose received within 3 months prior to randomization
•More than 1 month of cumulative use between 3 and 12 months prior to
randomization. Denosumab or any cathepsin K inhibitor,such as odanacatib:any dose
received within 18 months prior to randomization
Teriparatide or any PTH analogs:•any dose received within 3 months prior to randomization
•more than 1 month of cumulative use between 3 and 12 months prior
to randomization
Systemic oral or transdermal estrogen or SERMs:more than 1 month of
cumulative use within 6 months prior to randomization
Hormonal ablation therapy: more than 1 month of cumulative use within 6 months prior to randomization
Tibolone, cinacalcet or calcitonin:any dose received within 3 months
prior to randomization
Systemic glucocorticosteroids: = 5 mg prednisone equivalent per day for
more than 14 days within 3 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
-25(OH) 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 ULN as assessed by the central laboratory.
Current, uncontrolled hyper- or hypothyroidism, per subject report or
chart review. Uncontrolled hyperthyroidism is defined as TSH and T4
outside the normal range. Uncontrolled hypothyroidism is defined as
TSH>10.Current, uncontrolled hyperparathyroidism or history of
hypoparathyroidism, per subject report or chart review. Uncontrolled
hyperparathyroidism is defined as: PTH outside the normal range in
subjects with concurrent hypercalcemia; or PTH values >20% above the
ULN in normocalcemic subjects
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 min•Hypersensitivity to ALN or other constituents of ALN tablets•Pregnancy and lactation•Other contraindications to ALN based on the country-specific product
insert applicable to the specific study center•Significantly impaired renal function.
