As exceptions, hormone replacement therapy in female subjects and supplementation therapy with thyroxin, iron, calcium, folate and vitamin B12 at recommended doses is allowed. Vitamin D supplementation at doses of 20 µg/day or less is also allowed. The use of other vitamins, nutritional supplements and herbal products, at recommended doses, may be allowed at the investigator's discretion. Occasional use of paracetamol for pain is allowed.
• Any clinically significant abnormalities in screening laboratory test results, vital signs or physical examination findings that might influence the results of the study or cause a health risk for the subject if he/she takes part in the study.
• Estimated glomerular filtration rate (eGFR) below 60 ml/min/1,73 m2

  • Notable resting bradycardia (heart rate (HR) below 45 beats per minute (bpm)) or tachycardia (HR above 100 bpm);
  • Screening or baseline ECG with QRS and/or T wave judged to be unfavourable for a consistently accurate QT measurement (e.g., neuromuscular artifact that cannot be readily eliminated, arrhythmias, indistinct QRS onset, low amplitude T wave, merged T- and U-waves, prominent U waves);
  • Evidence of atrial fibrillation, atrial flutter, complete bundle branch block, Wolf-Parkinson-White syndrome, or cardiac pacemaker.
• History or evidence of current clinically significant, potentially unstable cardiovascular, pulmonary, renal, hepatic, gastrointestinal, haematological, metabolic-endocrine or urogenital disorder.

Personal or first-degree family history of congenital long QT syndrome or sudden death of a first-degree relative suspected to be due to long QT syndrome will also exclude the subject.
