- Low bone mineral density (BMD), defined as a BMD T-score between -1.0 and -2.5 at the lumbar spine (L1-L4) and/or femoral neck
- Weight ≤ 98 kg (216 lb) and/or height ≤ 196 cm (77 in)
- 25-hydroxyvitamin D ≥ 20 ng/mL at screening
- Willing and able to take ≥ 500 mg calcium and ≥ 400 IU (but ≤ 1,000 IU) vitamin D daily
Exclusion
- Osteoporosis, defined as a BMD T-score ≤ -2.5 at the lumbar spine or femoral neck
- History of vertebral fracture, or fragility fracture of the wrist, humerus, hip or pelvis
- Diagnosed with any condition that will affect bone metabolism
- Subjects with fewer than 2 evaluable vertebrae; metal in forearms bilaterally that would not allow for at least one evaluable forearm
- Administration of the following medications within 6 months before study drug administration. This includes all routes of administration, for example intranasal and topical skin patches, unless otherwise noted:
- Hormone replacement therapy \[(eg, estrogen, estrogen-like compounds such as raloxifene). Infrequent use of estrogen vaginal creams (\< 3 times per week) is allowed.\]
- Calcitonin
- Parathyroid hormone (or any derivative)
- Glucocorticosteroids (inhaled or topical corticosteroids administered more than 2 weeks before the enrollment date are allowed)
- Anabolic steroids
- Calcitriol, and available analogues
- Administration of daily, weekly, or monthly bisphosphonates (BP) unless meeting the following criteria:
- \< 2 weeks of BP use requires a 2-month washout period
- 2 weeks to 3 months of BP use requires a 9-month washout period
- 3 to 6 months of BP use requires a 1-year washout period
- \> 6 months of BP use requires a 3-year washout period;
- Greatly differing levels of physical activity or constant levels of intense physical exercise during the 6 months before study drug administration
- Known sensitivity to mammalian-derived drug preparations
- Known to be hepatitis B surface antigen, hepatitis C virus or human Immunodeficiency virus (HIV) positive or a known diagnosis of acquired immunodeficiency syndrome (AIDS)
- Any organic or psychiatric disorder, which, in the opinion of the investigator, poses a risk to subject safety and may prevent the subject from completing the study or interfere with the interpretation of the study results
- Unavailable for follow-up assessment or any concerns for subject's compliance with the protocol procedures
- Any other condition that might reduce the chance of obtaining data required by the protocol or that might compromise the ability to give truly informed consent
- History or evidence of a clinically significant disorder, condition or disease that, in the opinion of the Investigator or Amgen physician would pose a risk to subject safety or interfere with the study evaluation, procedures or completion
- Clinically significant abnormality during the screening physical examination, electrocardiogram (ECG) or laboratory evaluation
- Participation in another clinical study within 4 weeks of screening or within 5 times the half-life of the investigational agent in the other clinical study, if known
- Has donated or lost 400 mL or more of blood or plasma within 8 weeks of study drug administration
- Previous AMG 785 exposure
