Official Title: “An Open Label, Non-Comparative, Multi-Center Phase III Trial of the Efficacy, Safety, and Toleration of Extended Voriconazole in the Treatment of Invasive Fungal Infections”

Voriconazole is a new drug developed to treat fungal infections. As of March 1999, the drug had been studied in more than 1,900 healthy volunteers or patients with fungal infections.

This study will test extended use of voriconazole in patients with serious fungal infections for which there are no approved therapies, and in patients who did not improve with or could not tolerate standard therapy. It will evaluate the drug's safety, effectiveness, and toleration in these patients.

Patients previous enrolled in protocol 99-C-0094 who improved with voriconazole treatment are eligible for this study. Before beginning treatment, patients will have a physical examination, including blood and urine tests, and an eye examination. They may also have X-ray or CT imaging.

Voriconazole will then be given twice a day either by infusion into a vein or by tablets taken by mouth for up to 12 weeks. Patients will be examined at weeks 4, 8 and 12 of the study and one week after treatment stops. Blood and urine samples will be collected at each visit. An eye examination will be done at the end of the treatment period and at other visits if vision problems develop.

Voriconazole is active against fungal infections and may produce fewer side effects than standard therapy.

Study Type: Interventional

Study Design: Treatment, Efficacy Study

The objective of this study is to evaluate the efficacy, safety and toleration of voriconazole in the treatment of systemic or invasive fungal infections due to fungal pathogens for which there is no licensed therapy or that are unresponsive or intolerant to treatment with approved systemic antifungal agents. This trial is an extension of the Phase III multicenter, open label study investigating the utilization of voriconazole for the treatment of systemic or invasive fungal infections. Enrollment is targeted for 100 patients to be recruited from multiple centers. The patient population will consist of patients with proven deeply invasive fungal infection for which there is no licensed therapy or if the patient is failing or intolerant to treatment with approved systemic antifungal agents and currently on the voriconazole (99-C-0094) protocol. Voriconazole will be administered intravenously at 3-4 mg/kg q 12 hours or orally at 200-300 mg BID. Efficacy will be evaluated by clinical, radiological and microbiological response.

Intervention(s) in this Clinical Trial
