February 25, 2021 updated by: Xinhua Hospital, Shanghai Jiao Tong University School of Medicine

A Study of Bumetanide for the Treatment of Children With Autism Spectrum Disorder：a Randomized Double-blind Placebo-controlled Trial

The investigators are going to carry out a randomized double-blind placebo-controlled trial to study the efficiency and mechanism of bumetanide on the treatment of children with Autism Spectrum Disorder.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In consideration of the increasing number of autistic children and poor intervention effect in China, it is an urgent to find some effective medicine. Some studies have reported bumetanide, a classic diuretic, could improve autistic behaviors in both animal model and humans; while the efficiency of bumetanide on Chinese autistic chilren is unkonwn and the underlying mechanisms remain unfolding. The investigators aim at investigating whether bumetanide would improve the clinical symptoms in Chinese children with autism within a safe dosage and further study the physiological mechanism beneath.The investigators will regularly assess the participants' autism-related symptoms during medication, as well as the adverse effects of each patient. The investigators will carry out genome-wide association analysis (GWAS) from blood sample, related metabolites in nervous system and compare the concentration of the neurotransmitter in autistic brain before and after 3 months' treatmeat,and also will collect the EEG signal in autistic chilldren when the participants performing certain tasks before and after 3 months' treatment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Childhood Autism Rating Scale(CARS)
Time Frame: Day 0 and Day 90
CARS is a behaviour-rating scale used to assess the presence and severity of the symptoms of autism spectrum disorder
Day 0 and Day 90

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Clinical Global Impressions Scale (CGI)
Time Frame: Day 0 and Day 90
CGI is a scale used to assess the severity of the illness and the global improvement of the patient under intervention
