Overview
Brief Summary
The purpose of this study is to determine the effect of isavuconazole at steady state on the pharmacokinetics of midazolam in healthy adult subjects.
Detailed Description
Subjects will check-in on Day -1 and remain confined to the study center until the completion of study procedures on Day 14. Subjects will return to the study center for an outpatient follow-up visit on Day 21. Blood and urine samples will be taken at various times during the study.
Subjects will receive a single dose of oral midazolam syrup on Day 1. On Days 3 and 4, isavuconazole will be dosed orally three times daily (TID). On Days 5 through 13, isavuconazole will be dosed orally once daily (QD). A single dose of oral midazolam syrup will be administered on Day 12.
