An Open Label, Non-Comparative, Multicenter, Phase III Trial of the Efficacy, Safety and Toleration of Voriconazole in the Primary or Secondary Treatment of Invasive Fungal Infections

Phase 3

Completed

• Conditions: Mycoses

• Registration Number: NCT00001757
• Lead Sponsor: National Institute of Allergy and Infectious Diseases (NIAID)

Brief Summary

Invasive fungal infections are often life-threatening in persons with immunocompromise. Persons with prolonged neutropenia secondary to cytotoxic chemotherapies are at high risk for these infections. Patients undergoing bone marrow transplantation, receiving prolonged corticosteroid or other immunosuppressive therapies, and persons with HIV infection and AIDS are also at risk. With the use of currently approved antifungal therapy, many of these infections may still be associated with a high mortality. Amphotericin B in its conventional form, is the current standard treatment for most life-threatening fungal infections. Because of its nephrotoxicity and other adverse effects, alternatives to conventional amphotericin B have been sought. Alternated agents include three lipid formulations of amphotericin B, fluconazole, itraconazole. Although all of these agents are associated with a decrease in adverse effects, their efficacy in most life-threatening fungal infections has not been shown to be equivalent to conventional amphotericin B.

Voriconazole is an investigational antifungal drug currently being brought to phase III trials in the US. This azole has been shown active against many fungal pathogens in vitro. In animal models and early human trials this new agent has been shown to be effective against aspergillosis. It has been shown to be well-tolerated and is available in an intravenous and oral formulation.

This is a non-comparative, open label study to evaluate the efficacy, safety and toleration of voriconazole in the treatment of invasive fungal infections. This agent will be used as primary therapy in those fungal infections in which no antifungal agent is currently approved or in patients unable to tolerate the approved agent. Voriconazole will also be used as a secondary treatment in those patients who have failed therapy with the primary approved agent or are unable to tolerate that agent or have unacceptable toxicity.
