Sumario:Fosmanogepix is a first-in-class antifungal currently in Phase 2 clinical trials for the treatment of invasive fungal infections caused by Candida, Aspergillus and rare molds. Fosmanogepix is the N-phosphonooxymethylene prodrug of manogepix, an inhibitor of the fungal enzyme Gwt1. Manogepix demonstrates broad spectrum in vitro activity against yeasts and molds, including difficult to treat pathogens. Because of its novel mechanism of action, manogepix retains potency against many resistant strains including echinocandin-resistant Candida and azole-resistant Aspergillus. Manogepix is also active against pathogens that demonstrate intrinsic resistance to other drug classes, such as Scedosporium, Lomentospora prolificans, and Fusarium with variable activity against Mucorales. Fosmanogepix demonstrates significant in vivo efficacy in mouse and rabbit disseminated infection models due to C. albicans, C. glabrata, C. auris, C. tropicalis, Coccidioides immitis, and F. solani as well as pulmonary infection models of A. fumigatus, A. flavus, S. prolificans, S. apiospermum and Rhizopus arrhizus. Clinical trials demonstrated high oral bioavailability (>90%), enabling switching between fosmanogepix intravenous and oral formulations without compromising blood levels. Favorable drug-drug interaction, tolerability, and wide tissue distribution profiles are observed making fosmanogepix an attractive option for the treatment of invasive fungal infections. This systematic review summarizes the findings of published data on fosmanogepix.
