Primary Outcome Measures:
  • Success at End of Trial (EOT) - Success is defined as: The definition of success is (criteria a, b, c and d must be satisfied): a. i) Absence of all clinical signs and symptoms present at baseline and absence of any new signs and symptoms that may be [ Time Frame: Through 4 weeks ]

Secondary Outcome Measures:
  • Efficacy at the 2nd and 4th week after the end of therapy [ Time Frame: Through 4th week ]
  • Safety of the 2 mg/kg/day regimen [ Time Frame: Through 4 weeks ]

Estimated Enrollment: 39

Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
AmBisome® 2 mg/kg/day in a unique daily IV administration
Drug: AmBisome
Patients will receive 2mg/kg/day IV daily administration of AmBisome® over 30-60 minutes as a reaction to signs/symptoms and positive Candida culture

Detailed Description:
Subjects will be enrolled to receive intravenously AmBisome® at 2 mg/kg/day for a maximum of 4 weeks. Treatment will be discontinued in case of failure, adverse events precluding treatment or success. In case of success AmBisome® at 2 mg/kg/day should be administered for at least 5 days after the complete resolution of all clinical findings of an active infection or for at least 8 days after the last positive blood culture or culture from a normally sterile site. It is not recommended to declare failure (and therefore change treatment) before giving at least 5 days of antifungal therapy. Failures in patients given less than 5 days of treatment should be well documented (e.g. persistent positive cultures despite catheter removal, clinical deterioration in absence of any explanation other than the fungal infection). Follow-up evaluations will be conducted at 2 and 4 weeks after the end of AmBisome® therapy. At end of treatment (time point for success or failure) patients may be shifted to oral (not intravenous) antifungals at the discretion of the local investigator, once a complete response has been achieved, if secondary prophylaxis is deemed necessary.
