  • Presence of one or more of the following signs and symptoms of acute fungal infection within the prior 48 hours to initiation of study treatment:
  • Fever defined as oral temperature greater than or equal to 38 degrees C (100.4 degrees F); rectal or core temperature greater than or equal to 38.6 degrees C (101.4 degrees F), or axillary temperature greater than or equal to 37.5 degrees Celsius (99.5 degrees F). Hypothermia defined as rectal or core temperature less than 36.0 degrees C (96.8 degrees F).

  • Localized signs and symptoms of inflammation (swelling, heat, erythema or purulence at a site infected with Candida spp.).
  • Patient is classified in one of following categories based on previous antifungal treatment: received less than 48 hours of previous systemic antifungal therapy and no more than a single dose of echinocandin therapy prior to study entry; intolerant to infusion related toxicities of amphotericin B preparations despite appropriate supportive measures or serum creatinine increased by >1.5 mg/dl while receiving conventional or lipid amphotericin B therapy; or lack of clinical response and/or persistent positive blood culture after at least seven days of systemic antifungal treatment with a polyene or fluconazole at an adequate dose.
