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. |
