Safety, Efficacy, and Pharmacokinetics of Amphotericin B Lipid Complex

Safety, Efficacy, and Pharmacokinetics of Amphotericin B Lipid Complex at 10 mg/kg/d for 7 Days or 5.0 mg/kg/d for 14 Days as Induction Therapy for Disseminated Cryptococcosis in Patients With HIV

The purpose of this study is to determine if initial therapy with ABLC at 10/mg/kg/d for 7 days are at least effective as ABLC at 5.0 mg/kg/d X 14 days as induction treatment of patients with disseminated cryptococcosis and HIV.

This is a randomized, open label, prospective study of ABLC at 5.0 and 10.0 mg/kg/d for treatment of patients with cryptococcal meningitis. Patients will be randomly assigned in a 1:1 ratio to receive 5.0 or 10.0 mg/kg/d of ABLC as induction therapy for cryptococcal meningitis. Patients receiving 10 mg/kg/d doses will be treated with ABLC for 7 days whereas patients receiving ABLC at 5.0 mg/kg/d will receive 14 days of ABLC therapy. After completion of induction therapy subjects will receive long-term fluconazole maintenance therapy at the discretion of the treating physician. The study will be conducted at the Washington Hospital Center
