Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
A total of 185 participants were enrolled in the study, and 153 were not treated, because they no longer met study criteria, withdrew consent, or were alternate participants who were no longer needed. The remaining 32 participants received treatment.

  Description
Voriconazole, 200 BID (EM) Participants with functional CYP2C19 alleles (EM) received voriconazole, 400 mg, twice daily (BID) on Day 1, then 200 mg BID on Days 2 and 3. Voriconazole dose was given at least 1 hour after a meal.
Atazanavir/Ritonavir, 300/100 QD (EM) EM participants received atazanavir/ritonavir, 300/100 mg once daily (QD), on Days 11 through 20. Atazanavir/ritonavir dose was administered in the morning within 5 minutes of completing a light meal.

Atazanavir/ritonavir dose was administered in the morning within 5 minutes of completing a light meal, and 1 hour before voriconazole morning dose.
Voriconazole, 50 mg BID (PM) Participants who were poor metabolizers of CYP2C19 (PM)received voriconazole, 100 mg BID, on Day 1 then 50 mg BID on Days 2 and 3. Voriconazole dose was given at least 1 hour after a meal.
Atanazivir/Ritonavir, 300/100 QD + Voriconazole, 50 BID (PM) PM participants received atazanavir/ritonavir, 300/100 mg QD, plus voriconazole, 100 mg BID, on Day 21, then 50 mg BID on Days 22-30.
Atazanavir/Ritonavir, 300/100 QD (PM) PM participants received atazanavir/ritonavir, 300/100 mg QD, on Days 11 through 20. Atazanavir/ritonavir dose was administered in the morning within 5 minutes of completing a light meal.
