The Deferasirox-AmBisome Therapy for Mucormycosis (DEFEAT Mucor) Study

2014-07-23 21:30:26 | BioPortfolio

Summary

The purpose of this study is to determine if the addition of the medication, deferasirox, to standard antifungal therapy for the infection, mucormycosis, is safe and effective

Description

Because of its extremely high morbidity and mortality, it is imperative to look for new antifungal therapies to treat mucormycosis. The agents of mucormycosis are exquisitely sensitive to iron availability, and we and others have demonstrated that iron chelation therapy improves the survival of rodents with mucormycosis. Deferasirox (Exjade) is the first orally bioavailable iron chelator approved for use in the United States (US) by the Food and Drug Administration (FDA), with an indication for treatment of iron overload from chronic transfusions. In clinical studies, deferasirox has been well tolerated and effective in iron-overloaded patients.

Although the safety and efficacy of deferasirox have been extensively evaluated in iron-overloaded patients, there are minimal data in non-iron-overloaded patients or in infected patients. Therefore, the safety and efficacy of deferasirox in patients with mucormycosis is unclear, and confirming safety in the current study, at the currently planned dose, is required to lay the groundwork for a future phase III clinical trial.

This is a prospective, phase II, randomized, double-blinded, placebo-controlled study of liposomal amphotericin B (LAmB; AmBisome) plus deferasirox vs. LAmB plus placebo for mucormycosis infection. Twenty patients with proven or probable mucormycosis (except for isolated skin infection) by consensus EORTC/MSG criteria, who have received less than 14 days of antifungal therapy for mucormycosis, and who have had radiographic imaging by CT or MRI within the past 72 hours that shows evidence of infection, will be randomized to receive LAmB plus deferasirox or placebo (n = 10 per arm), with randomization stratified by study site.

The primary objective is to determine the safety and tolerability of adjunctive deferasirox therapy in patients being treated with LAmB for mucormycosis, and to obtain exploratory data on the efficacy of the iron chelation treatment. The exploratory efficacy endpoint will be the global response rate (composite of clinical and radiographic response) at end of study drug administration, as determined by a blinded adjudication committee.

Medical and Biotech [MESH] Definitions

A genus of zygomycetous fungi of the family Mucoraceae, order Mucorales. It is primarily saprophytic, but may cause MUCORMYCOSIS in man from spores germinating in the lungs.

An order of zygomycetous fungi, usually saprophytic, causing damage to food in storage, but which may cause respiratory infection or MUCORMYCOSIS in persons suffering from other debilitating diseases.

Infection in humans and animals caused by fungi in the class Zygomycetes. It includes MUCORMYCOSIS and entomophthoramycosis. The latter is a tropical infection of subcutaneous tissue or paranasal sinuses caused by fungi in the order Entomophthorales. Phycomycosis, closely related to zygomycosis, describes infection with members of Phycomycetes, an obsolete classification.

Infection in humans and animals caused by any fungus in the order Mucorales (e.g., Absidia, Mucor, Rhizopus etc.) There are many clinical types associated with infection of the central nervous system, lung, gastrointestinal tract, skin, orbit and paranasal sinuses. In humans, it usually occurs as an opportunistic infection in patients with a chronic debilitating disease, particularly uncontrolled diabetes, or who are receiving immunosuppressive agents.
