Inclusion Criteria

Panel A: Is undergoing treatment for possible, probable, or proven invasive fungal infection (IFI) known or suspected to be cause by fungal pathogens against which POS has demonstrated activity (which can include candidiasis)

Panel B: has an investigator-assessed diagnosis of possible, probable, or proven IFI known or suspected to be cause by fungal pathogens against which POS has demonstrated activity (and cannot include candidiasis)

Has a central line (eg, central venous catheter, peripherally-inserted central catheter) in place or planned to be in place before beginning IV study intervention

Has a body weight of ≥500 g

The participant (or legally acceptable representative) has provided documented informed consent for the study.

Exclusion Criteria

Has received POS within 30 days before Day 1

Has enrolled previously in the current study and been discontinued

Has QTc prolongation at screening >500 msec

Has significant liver dysfunction

Is hemodynamically unstable, exhibits hemodynamic compromise, or is not expected to survive at least 5 days

Has cystic fibrosis, pulmonary sarcoidosis, aspergilloma, or allergic bronchopulmonary aspergillosis.

Has a known hereditary problem of galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption

Has known or suspected active COVID-19 infection

Has a known hypersensitivity or other serious adverse reaction to any azole antifungal therapy, or to any other ingredient of the study intervention used

Has any known history of torsade de pointes, unstable cardiac arrhythmia or proarrhythmic conditions, a history of recent myocardial infarction, congenital or acquired QT interval (QT) prolongation, or cardiomyopathy in the context of cardiac failure within 90 days of first dose of study intervention

Has received any listed prohibited medications within the specified timeframes before the start of study intervention

Has a known hereditary problem of galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption (Panel B)
