Bioavailability of a novel sustained-release pellet formulation of 5-flucytosine in healthy-fed participants for use in patients with cryptococcal meningitis.

ABSTRACT: Cryptococcal meningoencephalitis (CM) is an opportunistic fungal infection and a major cause of death among people living with human immunodeficiency virus in sub-Saharan Africa. 5-flucytosine (5-FC) is a unique, brain-permeable antifungal agent used to reduce mortality from CM and to prevent disease in individuals carrying cryptococcal antigen. 5-FC has a short plasma half-life, requiring 6-hourly oral dosing with an immediate-release (IR) formulation, a significant challenge in hospital and outpatient settings, risking a lack of compliance. We recently reported the relative bioavailability in fasting conditions of a sustained release (SR) oral pellet formulation of 5-FC. In this phase I study, we assessed the safety and pharmacokinetic profiles of the new 5-FC SR formulation in a single
