Assigned Interventions
Experimental: 1

Children from 2 to 17 years who have possible, probable or proven invasive aspergillosis, or other rare mold infection (eg, Scedosporium and Fusarium).
Drug: Voriconazole

All subjects will receive voriconazole for a minimum of 6 weeks and a maximum of 12 weeks. All subjects must receive intravenous (IV) voriconazole for the first week of therapy.

Group 1: Subjects 2 to 11 years old and subjects 12 to 14 years old with low body weight (<50 kg) will receive 9 mg/kg IV every 12 hours (q12h) on day 1, then 8 mg/kg IV q12h starting day 2. If there is a significant clinical improvement after the first week of IV therapy, subjects may be switched to the step-down oral regimen (9 mg/kg PO q12h with a maximum dose of 350 mg PO q12h) at the discretion of the investigator.

Group 2: Subjects 12 to 17 years old (excluding 12-14-year-olds weighing <50 kg) will receive 6 mg/kg IV q12h on day 1, then 4 mg/kg IV q12h starting day 2. Similar to Group 1, subjects may be switched to the step-down oral regimen (200 mg PO q12h) at the discretion of the investigator. Oral voriconazole can be administered as tablet or oral suspension.
