Trial of Combination Antifungal Therapy (Vori+Mica vs. Vori+Placebo) in Invasive Aspergillosis

Inclusion Criteria: 1. The patient or legally authorized representative has signed an informed consent/assent. Assent will be obtained as required by the UAMS IRB. 2. The patient has a diagnosis of proven or probable invasive aspergillosis and with positive Aspergillus GM index (≥0.5 ng/ml) provide the patient is not receiving antibiotics, such as piperacillin-tazobactam, that are known to cause false positive GMI 3. The patient is 18 years of age or older. Exclusion Criteria: 1. The patient is being treated with an unlicensed investigational drug for aspergillosis. 2. The patient has been administered an antifungal agent (voriconazole, itraconazole, posaconazole, caspofungin, micafungin, anidulafungin, amphotericin B, or lipid formulation of amphotericin B) for \> 7 days immediately prior to randomization for treatment of the Probable, or Proven invasive aspergillosis for which the patient is being enrolled. 3. Patient has invasive aspergillosis but with negative Aspergillus GM index. 4. The patient is pregnant or lactating. If the patient is female and of childbearing potential, the patient must have a negative pregnancy test and avoid becoming pregnant while receiving study drug. A pregnancy test should be performed within 14 days prior to the first dose of study drug. 5. The patient has alkaline phosphatase, ALT, AST or total bilirubin greater than five times the upper limit of normal. 6. The patient has hepatic cirrhosis. 7. Patients with creatinine \> 3 will be enrolled only if able to receive oral voriconazole (specify oral loading dose is 6 mg/kg PO Q 12 hours for 24 hours) then oral maintenance 200 mg PO q 12 hours). 8. The patient is on artificial ventilation, and unlikely to be extubated within 24 hours of study entry. 9. The patient has a history of allergy, hypersensitivity, or any serious reaction to the azole or echinocandin class of antifungal agents. 10. The patient has previously enrolled into this study. 11. The patient has a concomitant medical condition, which in the opinion of the Investigator may create an unacceptable additional risk. 12. The patient has an active microbiologically-documented deep infection due to a non-Aspergillus mold. 13. The patient has a life expectancy of less than seven days.
