Intravenous (IV) caspofungin acetate 50 mg/day. Participants with esophageal candidiasis will be treated for at least 7 days and for at least 72 hours after symptoms resolve for a maximum of 28 days; participants with invasive candidiasis will have a 70 mg loading dose on study day 1 and will be treated for at least 14 days after the last positive culture of Candida from the blood or other normally sterile body site for a maximum of 60 days; these participants should also have improvement in clinical and radiographic signs of disease for at least 48 hours before completion of the study therapy.
Number of Participants With One or More Drug-related Serious Adverse Events
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.
Time frame: 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)
Number of Participants With One or More Drug-related Adverse Events
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.
Time frame: 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)
Number of Participants Who Discontinued Due to a Drug-related Adverse Event
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.
Time frame: 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)

Number of Participants With Favorable Overall Response for Esophageal Candidiasis or Invasive Candidiasis
Efficacy response for esophageal candidiasis was based on clinical and endoscopic criteria; favorable responses included complete and partial improvement in symptoms and endoscopic lesions. Efficacy response for invasive candidiasis was based on microbiological and clinical assessments; favorable responses required both favorable microbiological response (i.e., eradication or presumptive eradication based on symptoms, physical exam, and non-invasive tests) and complete or partial clinical response.
Time frame: First dose of study drug through up to 60 days of therapy (maximum 28 days of study drug for esophageal candidiasis, 60 days for invasive candidiasis; mean treatment duration of 14 days)
