Participants with hepatic impairment will be classified at screening based on Child-Pugh score. Classification will be repeated at check-in and should not be significantly different |
|
|
|
|
If the hepatic function classification for the participant is not similar at the 2 |
|
|
|
|
timepoints, enrollment of the participant into a hepatic category group will be at the |
|
|
|
|
discretion of the investigator, in consultation with the sponsor's medical monitor. The |
|
|
|
|
enrollment group will be based on the results at screening |
|
|
|
|
Participants eligible for Group 4 (normal hepatic function) should be in good health |
|
|
|
|
as determined by no clinically significant findings in the medical history, physical |
|
|
|
|
examination, vital signs, 12-lead ECGs, or laboratory examinations at screening or |
|
|
|
|
check-in |
|
|
|
|
Participants eligible for Groups 1 through 3 may have medical findings consistent with |
|
|
|
|
their degree of hepatic dysfunction, as determined by medical history, physical |
|
|
|
|
examination, vital signs, 12-lead ECGs, and clinical laboratory examinations at |
|
|
|
|
screening and check-in. Participants with abnormal findings considered not clinically |
|
|
|
|
significant by the investigator are eligible |

pacemaker)
|
|
|
|

included at the discretion of the investigator
