- •11.Have been treated with growth hormone, insulin-like growth factor 1, or anabolic steroids in the 6 months prior to Screening, or long-term treatment (> 3 months) at any time.
- •12.Have had regular long-term treatment ( > 1 month) with oral corticosteroids (low-dose ongoing inhaled steroid for asthma, or intranasal steroids, are acceptable) prior to Screening
- •13.Have ever had prior cervicomedullary decompression surgery.
- •14.Have had a fracture of the long bones or spine within 6 months prior to Screening.
- •15.Have aspartate aminotransferase, alanine aminotransferase, or total bilirubin > 2 × the upper limit of normal at Screening (except for subjects with a known history of Gilbert’s syndrome or transient indirect hyperbilirubinemia).
