Laborértékek

• Any clinically significant (at the discretion of the Investigator) abnormalities in laboratory test results. Total bilirubin value up to 1.5 times the upper normal limit of normal can be acceptable if associated with normal conjugated bilirubin value (unless the participant has documented Gilbert's Syndrome).
• Abnormal cardiac conditions and ECG:
