Primary Outcome Measures:
  • Serological response (evaluated by approved diagnostic serological tests [cryptococcosis, coccidiomycosis, and histoplasmosis]) at Weeks 2, 8, 12, and end of therapy. [ Time Frame: Weeks 2, 8, 12, and end of therapy ] [ Designated as safety issue: No ]
  • 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. [ Time Frame: Weeks 1, 2, 4, 8, 12 and end of therapy ] [ Designated as safety issue: No ]
  • 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. [ Time Frame: Weeks 2, 8, 12, and end of therapy ] [ Designated as safety issue: No ]
  • Mycological response (evaluated by the presences of fungal pathogen by relevant specimen [microscopy or histopathology]) at Weeks 2, 8, 12, and end of therapy. [ Time Frame: Weeks 2, 8, 12, and end of therapy ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Global response to treatment (incorporating clinical, mycological, radiological, and serological responses as applicable) at end of therapy/Week 16. [ Time Frame: End of therapy or Week 16 ] [ Designated as safety issue: No ]
  • Change from baseline in laboratory parameters at Weeks 1, 2, 4, 8, 12, end of therapy, Week 16, and follow-up. [ Time Frame: Weeks 1, 2, 4, 8, 12, end of therapy, Week 16, and follow-up ] [ Designated as safety issue: Yes ]
  • Change from baseline in electrocardiogram at Week 1 and end of therapy. [ Time Frame: Week 1 and end of therapy ] [ Designated as safety issue: Yes ]
  • Incidence of adverse events at Weeks 1, 2, 4, 8, 12, end of therapy, Week 16, and follow-up. [ Time Frame: Weeks 1, 2, 4, 8, 12, end of therapy, Week 16, and follow-up ] [ Designated as safety issue: Yes ]
  • Visual safety testing at Weeks 1, 8, 12, end of therapy, Week 16, and follow-up. [ Time Frame: Weeks 1, 8, 12, end of therapy, Week 16, and follow-up ] [ Designated as safety issue: Yes ]

Enrollment: 7
Study Start Date: April 2003
Study Completion Date: May 2004
Arms Assigned Interventions
Experimental: A Drug: Voriconazole
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.
