Exploratory
• To describe the effect of 6 months of treatment with HCP-administered romosozumab with PFS versus subject self-administered romosozumab with AI/Pen SC QM in postmenopausal women with osteoporosis on bone turnover markers (BTMs)

E.4 | Principal exclusion criteria |
Disease-Related
• History of ONJ and/or AFF
• History of metabolic or bone disease (except osteoporosis) that may interfere with the interpretation of the results, such as sclerosteosis, Paget’s disease, rheumatoid arthritis, osteomalacia, osteogenesis imperfecta, osteopetrosis, ankylosing spondylitis, Cushing’s disease, hyperprolactinemia, and malabsorption syndrome

• Vitamin D insufficiency [defined as serum 25 (OH) vitamin D levels < 20 ng/mL], as determined by the central laboratory. Vitamin D repletion will be permitted and subjects may be rescreened.
• Current hyperthyroidism (unless well controlled on stable antithyroid therapy) by subject report or by chart review, per principal investigator evaluation
• Current clinical hypothyroidism (unless well controlled on stable thyroid replacement therapy) by subject report or by chart review, per principal investigator evaluation
• Current, uncontrolled hyper- or hypoparathyroidism, defined as PTH outside the normal range, per subject medical history. Uncontrolled hyperparathyroidism is defined as: parathyroid hormone (PTH) outside the normal range in subjects with concurrent hypercalcemia; or PTH values > 20% above the upper limit of normal (ULN) in normocalcemic subjects.
• 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

Hepatitis status will be evaluated by testing for hepatitis B surface antigen (HepBsAg), total hepatitis B core antibody (HepBcAb) and hepatitis C antibody by the central laboratory at initial screening. Polymerase chain reaction (PCR) should be performed to confirm active disease only if total HepBcAb is positive and HepBsAg is negative or if C antibody is positive.
