6. Acromegaly

7. Current hyperparathyroidism or hypoparathyroidism by medical record.

8. Current hyperthyroidism or hypothyroidism (allowed if having normal hormone level on thyroid hormone replacement therapy or 5.5μIU/mL<thyroid-stimulating hormone (TSH) level≤10.0μIU/mL, but the serum thyroxine (T4) is within the normal range.

2. Oral bisphosphonates, allowed if patients had the following conditions :

• Cumulative use> 3 months but <3 years: ≥ 6 months before the last medication was taken from the screening visit;
