Outcomes

Primary Outcome Measures

Serological response (evaluated by approved diagnostic serological tests [cryptococcosis, coccidiomycosis, and histoplasmosis]) at Weeks 2, 8, 12, and end of therapy.
Clinical response (evaluated based on change of attributable symptoms, signs, and/or bronchoscopic abnormalities present at baseline, judged by investigators, at Weeks 1, 2, 4, 8, 12, and end of therapy) at Weeks 1, 2, 4, 8, 12, and end of therapy.
Radiological response (evaluated based on all radiological abnormalities [X-ray, computed tomography scan] attributed to fungal infection compared to baseline) at Weeks 2, 8, 12, and end of therapy.
Mycological response (evaluated by the presences of fungal pathogen by relevant specimen [microscopy or histopathology]) at Weeks 2, 8, 12, and end of therapy.

Secondary Outcome Measures

Global response to treatment (incorporating clinical, mycological, radiological, and serological responses as applicable) at end of therapy/Week 16.
Change from baseline in laboratory parameters at Weeks 1, 2, 4, 8, 12, end of therapy, Week 16, and follow-up.
Change from baseline in electrocardiogram at Week 1 and end of therapy.
Incidence of adverse events at Weeks 1, 2, 4, 8, 12, end of therapy, Week 16, and follow-up.
Visual safety testing at Weeks 1, 8, 12, end of therapy, Week 16, and follow-up.

Intervention Type
Drug
Intervention Name(s)
Voriconazole
Intervention Description
Oral or intravenous voriconazole. Oral tablets 400 mg twice daily loading dose on first day, followed by 200 mg twice daily taken at least 1 hour before or after a meal. Oral doses could be increased to a maximum of 300 mg twice daily if there was no clinical improvement after at least 3 days of treatment, no serious adverse events were reported, and clinical chemistry parameters were within the acceptable range for study entry. Intravenous treatment was initiated with a loading dose of 6 mg/kg twice daily for the first day followed by 4 mg/kg twice daily for at least 3 days (maximum infusion rate of 3 mg/kg/hr if administered by peripheral intravenous line). An intravenous loading dose was not required in patients who were restarted after oral treatment. Total duration of therapy (intravenous and oral) was 12 weeks.
