  • Impaired kidney function as judged by the investigator and/or creatinine clearance <50 mL/min and/or serum creatinine > 1.4 mg/dL
  • Participation in another interventional clinical study involving an investigational compound within 3 months prior to enrolment in this study or participation in another interventional clinical study involving an investigational compound during this study.
  • Subjects who are unable to comply with the requirements of the study or who in the opinion of the investigator should not participate in the study.
  • History or presence of alcohol abuse or drug abuse.
  • Patients with known history for, or presence of, anti-hGH and / or anti-PEG antibodies
