Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

ABCD treatment

Arm Description

In this single-arm research, patients were treated with ABCD 3.0-4.0 mg/kg/d (subject to adjustment, maximum dose not exceeding 6.0 mg/kg/d) combined with flucytosine 100 mg/kg/d for induction therapy of cryptococcal meningitis. The course of induction therapy is at least four weeks. Then, patients were treated with Fluconazole (400-600 mg/d) ± flucytosine (100 mg/kg/d) for consolidation therapy for at least 6 weeks.

Outcomes

Primary Outcome Measures

Complete response: live during the observation period, patients with cryptococcus meningitis all the clinical signs and symptoms disappeared, a significant reduction in the cerebrospinal fluid cryptococcal antigen test results and/or CSF cryptococcus training and/or ink staining (two consecutive tests, one week interval) results overcast, and abnormal head MRI/CT (if exist in baseline) improved or stable. Partial response: patient survival during the observation period, cryptococcal meningitis clinical signs and symptoms improved, all the significant reduction in the cerebrospinal fluid cryptococcal antigen test results and/or CSF cryptococcus training and/or ink staining (two consecutive tests, one week interval) results overcast, and abnormal head MRI/CT (if exist in baseline) improved or stable.

Proportion of patients with complete or partial response at 10 weeks
Complete response: live during the observation period, patients with cryptococcus meningitis all the clinical signs and symptoms disappeared, a significant reduction in the cerebrospinal fluid cryptococcal antigen test results and/or CSF cryptococcus training and/or ink staining (two consecutive tests, one week interval) results overcast, and abnormal head MRI/CT (if exist in baseline) improved or stable. Partial response: patient survival during the observation period, cryptococcal meningitis clinical signs and symptoms improved, all the significant reduction in the cerebrospinal fluid cryptococcal antigen test results and/or CSF cryptococcus training and/or ink staining (two consecutive tests, one week interval) results overcast, and abnormal head MRI/CT (if exist in baseline) improved or stable.
Proportion of patients with complete or partial response at the end of consolidation therapy
Complete response: live during the observation period, patients with cryptococcus meningitis all the clinical signs and symptoms disappeared, a significant reduction in the cerebrospinal fluid cryptococcal antigen test results and/or CSF cryptococcus training and/or ink staining (two consecutive tests, one week interval) results overcast, and abnormal head MRI/CT (if exist in baseline) improved or stable. Partial response: patient survival during the observation period, cryptococcal meningitis clinical signs and symptoms improved, all the significant reduction in the cerebrospinal fluid cryptococcal antigen test results and/or CSF cryptococcus training and/or ink staining (two consecutive tests, one week interval) results overcast, and abnormal head MRI/CT (if exist in baseline) improved or stable.

Brief Summary
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.
Detailed Description
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.
