Brief Summary

The purpose of this study is to assess the effect of multiple doses of isavuconazole on the pharmacokinetics (PK) of tacrolimus after single dose administration.

Detailed Description

Subjects will receive a single dose of tacrolimus on Day 1 followed by a 15 day wash-out period (time from tacrolimus dosing to isavuconazole dosing).

On Days 16 and 17, isavuconazole will be dosed three times daily (TID). TID doses will be administered 8 hours apart. On Days 18 through 28 isavuconazole will be administered once daily (QD). All subjects will be administered a single dose of tacrolimus on Day 20. A follow up visit will occur approximately 7 days after the last dose of isavuconazole. Blood samples for pharmacokinetics will be collected throughout the study.
