What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Subjects With Global Response of Success at End of Treatment
Time Frame: End of treatment (EOT) = Day 5 up to Day 42
Number of subjects with clinician assessed global response of success; defined as cure (resolution of signs and symptoms of Candida infection) or improvement (significant but incomplete resolution of signs and symptoms of Candida infection) on the clinical response in conjunction with eradication (follow up negative culture result for Candida species [spp]) or presumed eradication (follow up culture was not available and clinical outcome defined as success) on the microbiological response.
End of treatment (EOT) = Day 5 up to Day 42

Secondary Outcome Measures
