Inclusion Criteria

Male and female patients aged >= 18 years at the time of signing the informed consent.

Female patients must be non-lactating and at no risk for pregnancy for one of the following reasons:

- Postmenopausal for at least 1 year

- Post-hysterectomy and/or post-bilateral ovariectomy

- If of childbearing potential, having a negative urine or serum human chorionic gonadotropin (hCG) pregnancy test at screening and be using a highly effective method of birth control throughout the course of the study. Reliable sexual abstinence throughout the course of the study is acceptable as a highly effective method of birth control for the purposes of this study.

Patients who fall into one of the following 5 subgroups:

a) Patients with proven, probable or possible invasive aspergillosis who have renal impairment, defined as calculated [Table 10] creatinine clearance (CLcr) < 50 ml/min at

enrollment who require primary therapy.

NB: Patients fulfilling the criteria for â??possibleâ?? invasive aspergillosis who also have renal impairment will be eligible for enrollment; however, diagnostic tests to confirm the invasive aspergillosis as â??probableâ?? or â??provenâ?? by culture, histology/cytology or galactomannan (GM) antigen must be completed within 7 days after the first administration of study medication.

OR

b) Patients meeting EORTC/MSG definition [Appendix 1] of proven or culture positive probable IFD caused by rare molds, yeasts, or dimorphic fungi (i.e. fungal pathogens other than Aspergillus fumigatus or Candida species) whether renally impaired or not who require primary therapy for their IFD at the time of enrollment as defined in the body of the protocol.

OR

c) Patients who have zygomycosis and require primary therapy are eligible for enrollment.

Patients from the double-blinded WSA-CS-004 who had cultures positive for zygomycosis

may discontinue blinded study drug and instead roll-over into WSA-CS-003 to complete primary therapy.

OR

d) Patients meeting EORTC/MSG definition [Appendix 1] of proven or culture positive probable IFD caused by rare molds, yeasts, or dimorphic fungi (i.e. fungal pathogens other than Aspergillus fumigatus or Candida species) who are refractory to current treatment

defined as:

• clear documentation of progression of disease

NB radiological progression only in association with WBC recovery is not

Acceptable

or

• failure to improve clinically despite currently receiving at least 7 days of standard

antifungal regimen

Prior to enrolling patients that fall into this category, please contact the Medical Monitor for

approval.

OR

e) Patients meeting EORTC/MSG definition [Appendix 1] of proven or culture positive

probable IFD caused by rare molds, yeasts, or dimorphic fungi (i.e. fungal pathogens

other than Aspergillus fumigatus or Candida species) who are intolerant to current

treatment defined as:

• doubling of serum creatinine value to higher than the upper limit of normal

(ULN) within 48 hours

or

• serum creatinine > 2.0 mg/ml and current treatment with polyene or IV

voriconazole

or

• other significant drug-related adverse reaction(s) to the current antifungal agent,

resulting in discontinuation of the treatment, e.g. persistence of visu

Exclusion Criteria

Women who are pregnant or breastfeeding.

2. Known history of allergy, hypersensitivity, or any serious reaction to the azole class of

antifungals or to any component of the study medication.

3. Patients at high risk for QT/QTc prolongation such as:

- Baseline prolongation of QTcF 500 msec

- Risk factors for Torsade de Pointes (e.g. uncompensated heart failure, abnormal

potassium or magnesium levels that cannot be corrected, any unstable cardiac condition

during the last 30 days, or a family history of long QT syndrome);

- The use of concomitant medications that prolong the QT/QTc interval (See Table 5 for

examples).

4. Patients with evidence of hepatic dysfunction with any of the following abnormalities at the

time of enrollment (may be re-checked using local laboratory):

• Total bilirubin 3 x upper limit of normal (ULN) OR

• Alanine transaminase or aspartate transaminase 5 x ULN OR

• Patients with known cirrhosis or chronic hepatic failure

5. Concomitant use of sirolimus, astemizole, cisapride, rifampin/rifampicin, rifabutin, ergot

alkaloids, long acting barbiturates, ritonavir, efavirenz, carbamazepine, pimozide, quinidine,

neostigmine, terfenadine, ketoconazole, valproic acid or St. Johnâ??s Wort in the 5 days prior to

first administration of study medication.

6. Patients with either chronic aspergillosis, aspergilloma or allergic bronchopulmonary

aspergillosis (ABPA).

7. Microbiological findings (e.g. virological) or other potential conditions that are temporally

related and suggest a different etiology for the clinical features in the absence of evidence of

systemic fungal infection.

8. Advanced human immunodeficiency virus (HIV) infection with CD4 count 75 or

uncontrolled acquired immunodeficiency syndrome-defining condition.

9. Any known or suspected condition of the patient that may jeopardize adherence to the

protocol requirements or impede the accurate measurement of efficacy (e.g. neutropenia not

expected to resolve or patients with fungal endocarditis).

10. Patients with a concomitant medical condition that, in the opinion of the investigator, may be

an unacceptable additional risk to the patient should he/she participate in the study.

11. Patients previously enrolled in a phase III study with ISA (NB patients may be transferred

from study WSA-CS-004 if mycology identifies zygomycetes which is not expected to be

susceptible to voriconazole).

12. Treatment with any investigational drug in any clinical trial 30 days prior to the first

administration of study medication except open label protocols.

13. Patients who are unlikely to survive 30 days.

14. Patients with a body weight 40 kg.

15. Patients who need primary therapy for invasive aspergillosis who have been administered

more than 4 cumulative days of itraconazole, voriconazole, or posaconazole, for any reason,

within the 7 days prior to the first administration of study medication.

• Patients with applicable host factors who develop new evidence of IFD while on

prophylactic therapy, for at least 14 days, with either an amphotericin B product or an

echinocandin, will be eligible for enrollment.

• Prior use of fluconazole of any duration and any reason will
