Primary Outcome Measures:
  • To assess the safety and tolerability of anidulafungin when used to treat children with invasive candidiasis, including candidemia. [ Time Frame: Duration of the trial ]

Secondary Outcome Measures:
  • To assess rates of relapse at the Week 2 and Week 6 FU visits [ Time Frame: Week 2 and Week 6 FU visits ]
  • To assess all-cause mortality during study therapy and follow-up visits [ Time Frame: EOIVT, EOT, Week 2 and Week 6 FU visits ]
  • To explore pharmacokinetic parameters of anidulafungin in children aged 1 month to <2 years following IV infusion of anidulafungin (area under curve over dosing interval (AUC24) and peak concentration (Cmax)); [ Time Frame: Day 1 - Day 2 ]
  • To assess the efficacy of anidulafungin, as measured by global response, at the following time points: EOIVT, EOT, 2-week FU visit and 6-week FU visit [ Time Frame: EOIVT, EOT, Week 2 and Week 6 FU visits ]
  • To explore the exposure-response (safety and efficacy endpoints) relationship of anidulafungin using a nonlinear mixed effects approach as appropriate, including exploring the association between PK-PD index (eg, AUC/MIC) and efficacy endpoints; [ Time Frame: Day 1 - Day 9, at specified collection time points ]
  • To assess rates of new infection at the Week 2 and Week 6 FU visits [ Time Frame: Week 2 and Week 6 FU visits ]
  • • To explore pharmacokinetic parameters of polysorbate 80 following IV infusion of anidulafungin (AUC24 and Cmax) [ Time Frame: Day 1 - Day 9, at specified collection times ]

Estimated Enrollment: 60
Actual Study Start Date: February 27, 2009
Estimated Study Completion Date: June 12, 2019
Estimated Primary Completion Date: June 12, 2019 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Anidulafungin IV
All subjects meeting screening criteria will receive IV anidulafungin.
Drug: Anidulafungin

Day 1: loading dose of 3 mg/kg (not to exceed 200 mg) Day 2 onwards: maintain a dose of 1.5 mg/kg (not to exceed 100 mg). Minimum total treatment duration is 14 days. Minimum IV anidulafungin treatment duration is 10 days for subjects with microbiologically confirmed ICC and 5 days for subjects at risk of candidiasis; followed by oral fluconazole 6-12 mg/kg/day (not to exceed 800mg/day).

Maximum treatment duration with anidulafungin is 35 days.

Other Name: Eraxis
Drug: Fluconazole
Subjects may be switched to oral fluconazole [6-12 mg/kg/day (not to exceed 800mg/day] provided they meet specified criteria. Maximum total treatment duration is 49 days.
Other Name: Diflucan

Detailed Description:
Prospective, open label study to assess the pharmacokinetics, safety & efficacy of anidulafungin when used to treat children (aged 1 month - < 18 years) with invasive candidiasis, including candidemia (ICC). To participate in the study, at the time of enrollment subjects must (1) have either a confirmed diagnosis of ICC or mycological evidence highly suggestive of Candida sp or (2) in infants 1 month to < 2 years only, be at high risk of candidiasis. All subjects meeting screening criteria receive IV anidulafungin. Subjects will be stratified by age (1 month - < 2 years; 2 years - < 5 years; 5 years - < 18 years). Subjects may be switched to oral fluconazole, provided that the pre-specified criteria are met. Subjects with microbiologically confirmed ICC must have a minimum total treatment duration of 14 days. The maximum allowed treatment duration of anidulafungin is 35 days; the maximum total treatment duration for the study is 49 days. At selected centers, anidulafungin pharmacokinetics will be assessed in the first 6 subjects age 1 month - < 2 years to confirm the recommended dosage regimen. A population PK-PD analysis will be performed in all other enrolled subjects. Subjects will be followed for safety through 6 week FU visit. Efficacy for subjects with confirmed ICC will be assessed at EOIVT, EOT, 2-week FU and 6-week FU visits.

Ages Eligible for Study:   1 Month to 17 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subject must be either (1) at high risk for candidiasis (1 month - < 2 years ONLY) or (2) have a definitive diagnosis of invasive candidiasis/candidemia (ICC) (All age groups)
  • Male and female patients from 1 month to less than 18 years of age.

Exclusion Criteria:

  • Any patients with allergy to the drug; and any pregnant female or lactating.
  • Failed previous antifungal therapy or expected to live < 3 days.
  • Patients with documented or suspected Candida meningitis.
