  • •15. Patient has any condition or in any situation which, in the investigator’s opinion, puts the patient at significant risk, could confound study results, or may interfere significantly with the patient’s participation in the study
  • •*In the event that lab value is above the specified threshold, it can be repeated. If repeat value is within specified range, patient can continue
