Voriconazole With or Without Interferon Gamma in Treating Patients With Aspergillosis or Other Fungal Infections
RATIONALE: Antifungals such as voriconazole may be effective in controlling fungal infections. Combining voriconazole with interferon gamma may be more effective than voriconazole alone in treating fungal infections.
PURPOSE: Randomized phase II trial to compare the effectiveness of voriconazole with or without interferon gamma in treating patients who have aspergillosis or other fungal infections.
Unspecified Adult Solid Tumor, Protocol Specific
Biological: recombinant interferon gamma
|Study Design:||Allocation: Randomized
Primary Purpose: Supportive Care
|Official Title:||A Prospective, Randomized, Double-Blind, Multicenter Pilot Study Of The Safety And Efficacy Of Interferon Gamma- 1b (IFN-y 1b) Plus Voriconazole Versus Placebo Plus Voriconazole In The Treatment Of Invasive Aspergillosis And Other Filamentous Fungal Infections|
|Study Start Date:||August 2003|
|Study Completion Date:||January 2005|
- Determine the safety profile of voriconazole and interferon gamma in patients with invasive aspergillosis or other filamentous fungal infections.
- Compare the efficacy and possible heterogeneity in efficacy of voriconazole with or without interferon gamma across different patient sub-populations, in terms of designing a larger phase II or pivotal phase III study.
- Determine the time to partial or complete response and rate of response (at weeks 6 and 12 or at end of treatment and follow-up) in patients receiving interferon gamma.
- Compare the proportion of patients with at least a two-fold reduction in the galactomannan antigenemia titer at 6 and 12 weeks or at end of treatment with these regimens.
- Determine surrogate immunologic markers for response to interferon gamma, functional integrity and anti-fungal activity of phagocytic cells (neutrophils, monocytes, and macrophages), and nonphagocytic effector cells (natural killer and T cells) in these patients.
OUTLINE: This is a randomized, double-blind, multicenter, pilot study. Patients are stratified according to age (under 18 vs 18 and over) and absolute neutrophil count (less than 500/mm^3 vs at least 500/mm^3). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive voriconazole (IV over 80-120 minutes for the first 3 doses and orally every 12 hours for subsequent doses) 3 times per week and interferon gamma subcutaneously (SC) 3 times per week.
- Arm II: Patients receive voriconazole as in arm I and placebo SC 3 times per week.
In both arms, treatment continues for 12 weeks in the absence of disease progression or unacceptable toxicity.
Patients are followed at 4 weeks.
PROJECTED ACCRUAL: A total of 88 patients (44 per treatment arm) will be accrued for this study.
