Clinical Study of ABCD in the Treatment of Cryptococcal Meningitis

Clinical Study of Amphotericin B Colloidal Dispersion (ABCD) in the Treatment of Cryptococcal Meningitis

To evaluate the efficacy and safety of ABCD in the treatment of cryptococcal meningitis in non-HIV patients at week 4, the end of induction therapy, week 10 and the end of consolidation therapy.

This study is a multi-center, single-arm clinical study. The objective is to evaluate the efficacy and safety of ABCD in the treatment of cryptococcal meningitis in non-HIV patients. Qualified subjects shall receive cryptococcus induction therapy with ABCD combined with flucytosine for at least 4 weeks, or termination of treatment early at the investigator's discretion. Efficacy and safety are followed up at week 4 (day 28), the end of induction therapy, week 10 (day 70) and the end of consolidation therapy.

• Patients with impaired renal function (renal function index blood creatinine (Cr) is more than 2 times higher than ULN, or 24-hour urine creatinine clearance rate （Ccr） is less than 50ml/min), or patients requiring/undergoing hemodialysis or peritoneal dialysis;
