Study Details

Study Description

Brief Summary

This study is designed as two sequential trials. The first is a phase I open label trial to evaluate the safety and tolerability of MAT2203. The maximal tolerated and non-toxic daily dose,will then be moved forward into a multi-day safety trial. The Phase II trial will investigate toxicity and early fungicidal activity (EFA) of MAT2203 with flucytosine.

Condition or Disease Intervention/Treatment Phase
Phase 1/Phase 2

Detailed Description

Cryptococcal meningitis has emerged as one of the most frequent and deadly opportunistic infections in HIV patients. Historically, amphotericin B (AMB) has been considered the "gold standard" in antifungal treatments due to its broad spectrum of activity and lack of emergence of resistance. However, the use of AMB is limited by side effects, including nephrotoxicity, anemia, and infusion-related reactions. MAT2203 or encochleated oral amphotericin B (cAMB) is a lipid nano-crystal formulation designed for targeted oral delivery of the antifungal drug AMB for treatment of fungal and parasitic infections.
