Eligibility Inclusion Criteria:

- Diagnosis of osteopenia for women (BMD T-scores between -1.0 and - 2.5 SD at the lumbar spine, the femoral neck or total hip)

- Body Mass Index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >45 kg (99 lbs).

- Have at least 3 vertebral bodies in the L1-L4 region and one femoral neck site that are accessible by DXA.

Exclusion Criteria:

- Evidence or history of any underlying condition, other than primary osteopenia, that affect bone metabolism (eg, hyperparathyroidism, hypoparathyroidism).

- Subjects with pre-existing periodontal/dental disease or those who have undergone invasive dental procedures (eg, tooth extraction, oral surgery) within 60 days prior to Day -1.

- If QTcF exceeds 455 msec, the ECG should be repeated two more times and the average of the three QTcF values should be used to determine the subject's eligibility.

Secondary Percentage change from baseline (average of Day -1 and Day 1 prior to infusion of RN564) in serum PINP, NTX, CTX, bone specific alkaline phosphatase and osteocalcin over time inclusive of 85 days. Days -1, 1, 2, 3, 4, 5, 8, 15, 22, 29, 36, 43, 57 and 85 No
Secondary Percentage change from baseline in lumbar spine, total hip, femoral neck and distal radius BMD at Day 85. Day -1 and 85 No
Secondary PK/PD model describing the relationship between RN564 PK parameter estimates/concentrations and changes in pharmacodynamic endpoints. Duration of the study No
