  13. History or evidence of QT prolongation or clinically significant QT prolongation (QTcF > 450 msec) at screening, or other significant ECG findings at screening that may place the subject at increased risk by participating in the study

  14. Treatment with any type of insulin (injected or inhaled) for > 6 consecutive days within 6 months prior to screening or any insulin therapy within 12 weeks prior to screening

  15. Treated with peroxisome proliferator-activated receptor-gamma agonists (thiazolidinediones [TZDs]), incretin therapy (GLP-1 agonists). or amylin mimetics within 12 weeks prior to screening
