Study Endpoints
Primary Endpoints
Number of Participants With a Significant Drug-related Adverse Experience
1-4 weeks for esophageal candidiasis, 2-8 weeks for invasive candidiasis, 2-12 weeks for aspergillosis

A significant drug-related adverse experience was defined as a serious drug-related adverse experience or a drug-related adverse experience leading to study therapy discontinuation.

Number of Participants With One or More Drug-related Serious Adverse Events
First dose of study drug through 14 days post therapy (maximum 28 days of study drug for esophageal candidiasis, 60 days for invasive candidiasis; mean treatment duration of 14 days)

A serious adverse event is one that results in death, disability/incapacity, or hospitalization or is life threatening, a congenital anomaly or birth defect, cancer, an overdose, or otherwise jeopardizes the patient and may require medical intervention. A drug-related adverse event is a determination by the investigator physician that the study drug caused the event based on exposure, time course, likely cause, dechallenge (event resolved/improved when drug was discontinued), rechallenge (event resolved/improved when drug was re-introduced), and consistency with the drug profile.

Any clinical or laboratory serious drug-related adverse experience during the study drug therapy period plus 14 days posttherapy.
during the study drug therapy period plus 14 days posttherapy
Plasma drug-level observed in children 3 to 24 months of age is similar to the levels observed in adults.
