- Key Exclusion Criteria
Excluded Medications at Enrollment
- Medications that are known to interact with POS or FLU and that may lead to serious or life threatening side effects within 7 days prior to initiating study drug;
- Medications known to lower the serum concentration/efficacy of azole antifungals within 7 days prior to study drug start;
- Prior investigational drug use or biologic product administration within 30 days before study drug start;
- Prior antifungal treatment for the current episode of infection with a total cumulative dose of >=8 g of any azole, >=4 mg/kg of amphotericin B deoxycholate, or >=20 mg/kg of lipid amphotericin B;
Antiretrovirals that are substrates of CYP3A4 administered to HIV-positive subjects, as it is not currently known how POS or FLU may affect such drugs or the potential to cause adverse reactions.

- Excluded Baseline Laboratory Studies
- Moderate or severe liver dysfunction (aspartate aminotransferase (AST) or alanine aminotransferase (ALT) > 5 times upper limit of normal (ULN)) or a total bilirubin level or direct bilirubin > 3 times ULN plus ALT or AST >2 times ULN (Hy's Rule);
- Moderate or severe renal dysfunction (creatinine clearance (CrCl) <20 mL/min) or dialysis required or expected to be required within the study period;
Electrocardiogram (ECG) with a prolonged QTc interval by manual reading: QTc >450 msec for males and QTc >470 msec for females.
- General Exclusion Criteria
- Prior enrollment in this study or other POS studies;
- Failed treatment with FLU or POS at any time in the past;
- History of hypersensitivity or idiosyncratic reactions to azole drug therapy;

Experimentální: Posaconazole
Eligible subjects will be stratified at Baseline by disease site (skeletal, lung, or soft tissue) and by immune status (immunocompromised or non-immunocompromised) and will then be randomly assigned to receive Posaconazole 400 mg orally (PO) (oral suspension 40 mg/mL) administered twice daily with meals or oral nutritional supplements for 12 months.

Treatment-emergent adverse events are defined as new events that occur following subject entry into the study or events that worsen following study entry state. Treatment-related adverse events are defined as new events that occur following subject entry into the study or events that worsen following study entry state and are judged by the investigator to be possibly, probably or definitely related to study medication. |

Severity grading was based on Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0.
This is a descriptive terminology which can be utilized for Adverse Event (AE) reporting.
A grading (severity) scale is provided for each AE term.
CTCAE displays Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild AE; Grade 2 Moderate AE; Grade 3 Severe AE; Grade 4 Life-threatening or disabling AE; Grade 5 Death related to AE.
