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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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)
Secondary outcomes (3)
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.
Measured: 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.
Measured: 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.
Measured: 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)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing caspofungin acetate in people with Fungal Infection, run by Merck Sharp & Dohme LLC.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 28 May 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With One or More Drug-related Serious Adverse Events (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)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00635648, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Mar 2017.
