MAT2203 is an orally administered lipid nanocrystal formulation of amphotericin B, which has been shown to be safe and effective against other fungal infections. We sought to compare the efficacy of MAT2203 to liposomal amphotericin B (LAMB) treatment in a neutropenic mouse model of IM due to\n                      <jats:italic>Rhizopus arrhizus<\/jats:italic>\n                      var.\n                      <jats:italic>delemar<\/jats:italic>\n                      or\n                      <jats:italic>Mucor circinelloides f. jenssenii<\/jats:italic>\n                      DI15-131.
