Brief Summary
In this study we will measure the concentration of the drug called voriconazole which is used to fight infections caused by fungus in children who usually are cancer patients and have their immune system down. Since we know the dose in adults, and we think we know the matching doses in the young patients ages 2 to 12 years old, we will compare the amount of drug that goes into the system with what we know works in adults. We give the drug by a needle directly into the blood, then few days later we stop that and give the drug by mouth. Meanwhile, we draw a little bit of blood at certain times to measure the drug in it.

Outcome Measures
Primary Outcomes (6)
Area Under the Curve Over Dosing Interval at Steady State (AUC12,ss) Following IV Administration
AUC12,ss = Area under the plasma concentration-time profile from time zero (predose) to twelve hours at steady-state. AUC12,ss was obtained by the Linear/Log trapezoidal method.
Day 7 (up to Day 20 or more) at predose, 60 and 138 minutes, 4, 6, 8 and 12 hours postdose
Peak Plasma Concentration at Steady State (Cmax,ss) Following IV Administration
Day 7 (up to Day 20 or more) at predose, 60 and 138 minutes, 4, 6, 8 and 12 hours postdose
Time to Reach Cmax (Tmax) Following IV Administration
Day 7 (up to Day 20 or more) at predose, 60 and 138 minutes, 4, 6, 8 and 12 hours postdose
AUC12,ss Following Oral Administration
AUC12,ss = Area under the plasma concentration-time profile from time zero (predose) to twelve hours at steady-state. AUC12,ss was obtained by the Linear/Log trapezoidal method.
Day 7 (or later) predose, 1, 2, 4, 6, 8 and 12 hours postdose
Cmax,ss Following Oral Administration
Day 7 (or later) predose, 1, 2, 4, 6, 8 and 12 hours postdose
Tmax Following Oral Administration
Day 7 (or later) predose, 1, 2, 4, 6, 8 and 12 hours postdose
Secondary Outcomes (10)
AUC12 Following IV Loading Dose
Day 1 predose, 60 and 138 minutes, 4, 6, 8 and 12 hours postdose
Cmax Following an IV Loading Dose
Day 1 predose, 60 and 138 minutes, 4, 6, 8 and 12 hours postdose
Tmax Following an IV Loading Dose
Day 1 predose, 60 and 138 minutes, 4, 6, 8 and 12 hours postdose
Trough Concentrations (Cmin)
Day 7 (up to Day 20 or more) for IV; Day 7 (or later) for oral at predose
AUC12,ss of N-oxide Voriconazole Metabolite (UK-121, 265) Following IV Administration
Days 1 and 7 (up to Day 20 or more) predose, 60 and 138 minutes, 4, 6, 8 and 12 hours postdose
- +5 more secondary outcomes
Study Arms (1)
Children aged 2 to <12 years
EXPERIMENTALImmunocompromised children aged 2 to \<12 years who are at high risk for systemic fungal infection.
Interventions
Study Days 1 to 7: IV voriconazole 7 mg/kg q12h. Study Days 8 to 14: Oral voriconazole (POS) 200 mg q12h Notes: 1. If unable to switch to oral medication on Day 8, subjects can continue with IV treatment up to Day 20 before switching to oral dose. 2. Only morning oral dose will be given on Day 14 (or the seventh day of oral dosing if IV regimen is extended). However, if clinically indicated, voriconazole treatment may be continued up to Day 30. (IV = Intravenous; POS = Powder for oral suspension)
Eligibility Criteria
You may qualify if:
- Male or female from 2 to \<12 years of age.
- Require treatment for the prevention of systemic fungal infection.
- Expected to develop neutropenia (ANC \<500 cells/μL) lasting more than 10 days following chemotherapy.
- Anticipated to live for more than 3 months.
You may not qualify if:
- Evidence of any clinically significant liver or renal function or other abnormalities such as cardiac arrhythmia, hypokalemia, hypomagnesemia or hypocalcemia.
- Documented bacterial or viral infection not responding to appropriate treatment.
- Hypersensitivity to or severe intolerance of azole antifungal agents.
- Receiving other azoles or drugs that is are prohibited in the voriconazole label or associated.
