Group Intervention Description Amphotericin B deoxycholate amphotericin B deoxycholate Infants received amphotericin B deoxycholate (CAB) at a dose of 1.0 mg/kg per day by intravenous infusion for a minimum of 21 days to a maximum of 28 days for infants without end-organ dissemination or for a maximum of 42 days for infants with end-organ dissemination. Micafungin micafungin Infants received micafungin at a dose of 10 mg/kg per day by intravenous infusion for a minimum of 21 days to a maximum of 28 days for infants without end-organ dissemination or for a maximum of 42 days for infants with end-organ dissemination.
- Primary Outcome Measures
Name Time Method Fungal-free Survival One week after the last dose of study drug (maximum of 49 days) Fungal-free survival was assessed by an independent data review panel (DRP). Fungal-free survival is defined as the percentage of participants alive at one week following the last dose of study drug with a mycological response of eradication and no requirement for alternative systemic antifungal therapy for continued treatment.
Eradication was defined as culture or histologically documented absence of the infecting Candida species from all positive normally sterile sites during therapy, documented by 2 negative samples, drawn at least 24 hours apart, or for Candida meningitis and/or candiduria, 1 negative culture.
- Secondary Outcome Measures
Name Time Method Percentage of Participants With Emergent Fungal Infections Up to 30 days after the last dose of study drug (maximum of 72 days) An emergent fungal infection is defined as
* An invasive fungal infection which is detected at any time during the study that is a non-Candida organism, or
* An invasive fungal infection which is detected during the treatment or post-treatment period with a Candida species identified other than those detected at Baseline. If this occurred within 96 hours of the first dose of study drug, the infection was considered part of the final diagnosis of enrolling infection and not an emergent infection.Time to Mycological Clearance of Invasive Candidiasis From first dose up to 30 days after the last dose of study drug (maximum of 72 days) Time to mycological clearance of invasive candidiasis is defined as the time from first dose to the day of mycological eradication for baseline invasive candidiasis infection.
Eradication was defined as a culture or histologically documented absence of the infecting Candida species from all positive normally sterile sites during therapy, documented by 2 negative samples, drawn at least 24 hours apart, or for for Candida meningitis and/or candiduria, 1 negative culture.
Infants without eradication during the treatment period and who survived were censored at one day after the end of treatment. Infants without eradication who died before completing the treatment period or were lost to follow-up during the treatment were censored at their death or last contact day.Clinical Response at the End of Study Drug Therapy Baseline and end of study drug therapy; maximum of 42 days Clinical response assessments were based on the following definitions and assessed by the DRP:
* Complete Response: Resolution of all attributable signs related to fungal infection, if present at baseline.
* Partial Response: Improvement in attributable signs related to the fungal infection, if present at baseline.
* Stabilization: Minor improvement or no change in attributable signs related to the fungal infection, if present at baseline, and infant continued on therapy without deterioration.
* Progression: Deterioration in attributable signs related to the fungal infection, if present at baseline; or if death occurred presumably related to a fungal infection.Mycological Response at End of Study Drug Therapy End of study drug therapy; maximum of 42 days Mycological response assessments were based on the following definitions and assessed by the DRP:
* Eradication: Culture or histologically documented absence of the infecting Candida species from all positive normally sterile sites during therapy, documented by 2 negative samples, drawn at least 24 h apart; for Candida meningitis and/or candiduria, 1 negative culture.
* Persistence: Continued isolation or histological documentation from a normally sterile site.Fungal-free Survival at End of Study Drug Therapy in Infants With End-organ Dissemination The end of study drug therapy; maximum of 42 days Fungal-free survival was assessed by an independent data review panel (DRP). Fungal-free survival is defined as the percentage of participants alive at the end of study drug therapy with a mycological response of eradication based upon the DRP assessment and no requirement for alternative systemic antifungal therapy for continued treatment.
Percentage of Participants With Recurrent Fungal Infections Up to 30 days after the last dose of study drug (maximum of 72 days) A recurrent infection is defined as a systemic fungal infection in an infant with eradication at the end of study drug therapy, who developed positive blood cultures or a mycologically confirmed deep-seated Candida infection, with the same species as the enrolling infection.
Time to Positive Clinical Response From first dose up to 30 days after the last dose of study drug (maximum of 72 days) Time to a positive clinical response is defined as the time from the first dose to the day during the treatment period that a positive clinical response (defined as a complete response or partial response) is observed for the first time, assessed by the Investigator.
Complete Response is defined as the resolution of all attributable signs related to fungal infection, if present at baseline and Partial Response is defined as improvement in attributable signs related to the fungal infection, if present at baseline.
Infants without positive responses and who survived were censored at one day post the end of treatment. Infants without positive responses who died before completing the treatment period, or were lost to follow-up during the treatment were censored at their death or last contact day.Fungal-free Survival One Week After Last Dose of Study Drug in Infants With End-organ Dissemination One week after the last dose of study drug (maximum of 49 days) Fungal-free survival was assessed by an independent data review panel (DRP). Fungal-free survival is defined as the percentage of participants alive one week after last dose of study drug with a mycological response of eradication based upon the DRP assessment and no requirement for alternative systemic antifungal therapy for continued treatment.
Clinical Response One Week After Last Dose of Study Drug Baseline and one week after the last dose of study drug (maximum of 49 days) Clinical response assessments were based on the following definitions and assessed by the DRP:
* Complete Response: Resolution of all attributable signs related to fungal infection, if present at baseline.
* Partial Response: Improvement in attributable signs related to the fungal infection, if present at baseline.
* Stabilization: Minor improvement or no change in attributable signs related to the fungal infection, if present at baseline, and infant continued on therapy without deterioration.
* Progression: Deterioration in attributable signs related to the fungal infection, if present at baseline; or if death occurred presumably related to a fungal infection.Mycological Response One Week After Last Dose of Study Drug One week after the last dose of study drug (maximum of 49 days) Mycological response assessments were based on the following definitions and assessed by the DRP:
* Eradication: Culture or histologically documented absence of the infecting Candida species from all positive normally sterile sites during therapy, documented by 2 negative samples, drawn at least 24 h apart; for Candida meningitis and/or candiduria, 1 negative culture.
* Persistence: Continued isolation or histological documentation from a normally sterile site.Follow-up Status for Infants With End-organ Assessments Baseline and 30 days after the last dose of study drug (maximum of 72 days) End-organ dissemination was assessed through abdominal ultrasound and/or computed tomography (CT), echocardiogram, head imaging and retinal exam. Each specific finding, documented by 1 of these techniques, was evaluated as follows:
* Improvement: Improvement in size, number or density of identified lesions. Complete response was not expected but may have been documented.
* Stabilization: Minor improvement or no change in size, number or density of identified lesions.
* Worsening: Increase in size or number of identified lesions.Plasma Micafungin Concentration 15 minutes post intravenous infusion (IV), 4-8 hours post IV and 15-24 hours post IV
