• Subject has evidence of any of the following:

1. Current, uncontrolled hyper- or hypothyroidism. Uncontrolled hyperthyroidism is defined as thyroid-stimulating hormone (TSH) and thyroxine (T4) outside of the normal range. Uncontrolled hypothyroidism is defined as TSH >10

2. Current, uncontrolled hyperparathyroidism or history of hypoparathyroidism. Uncontrolled hyperparathyroidism is defined as PTH outside the normal range in subjects with concurrent hypercalcemia or PTH values >20 % above upper limit of normal (ULN) in normocalcemic subjects

3. Current hypercalcemia or hypocalcemia, defined as albumin-adjusted serum calcium outside the normal range, as assessed by the central laboratory at the time of Screening. Albumin-adjusted serum calcium levels may be retested once in case of an elevated albumin-adjusted serum calcium level within 1.1xULN of the laboratory's reference ranges

4. Subject has =3xULN of any of the following: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), or >ULN total bilirubin (=1.5xULN total bilirubin if known Gilbert's syndrome). If subject has elevations only in total bilirubin that are >ULN and <1.5xULN, fractionate bilirubin to identify possible undiagnosed Gilbert's syndrome (ie, direct bilirubin <35 %)

Primary	Incidence of treatment-emergent adverse events (TEAEs)	An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
