To Evaluate the Effect of Glibenclamide in Reducing Brain Edema of TBI

November 24, 2021 updated by: Guangzhi Shi, Beijing Tiantan Hospital

Evaluation of Safety and Efficacy of Glibenclamide in the Treatment of Severe Traumatic Brain Injury

Brain edema is one of the main mechanisms of secondary brain injury and one factor in the prognosis of traumatic brain injury . The clinical study of glibenclamide in the treatment of brain edema after traumatic brain injury is designed to evaluate whether glibenclamide treatment can improve the blood NSE and S100β levels of severe traumatic brain injury , so order to explore the efficacy and adverse effects of this drug in the treatment of traumatic brain injury .

Detailed Description

Traumatic brain injury has high morbidity,disability and mortality ; worldwide, more than 50 million new cases , mainly low and middle-income countries.The annual incidence of craniocerebral trauma in China is (55 - 64) / 100000 , with 770 - 890 thousand new cases,causing nearly 100000 deaths and hundreds of thousands of disabilities , which is a serious public safety problem .Injury mechanisms after traumatic brain injury include primary and secondary brain injury and have a lack of effective treatment .Brain edema is one of the main mechanisms of secondary brain injury and one factor in the prognosis of traumatic brain injury .In recent years , the Sur1-Trpm4 channel was found to play an important role in the onset of brain edema , with increased expression in traumatic brain injury , ischemic stroke , and ischemic and hypoxic encephalopathy , and the specific inhibitor glibenclamide can reduce brain edema .A clinical study of glibenclamide in the treatment of brain edema after traumatic brain injury to evaluate whether glibenclamide treatment can improve the blood NSE and S100β levels of severe traumatic brain injury , so order to explore the efficacy and adverse effects of this drug in the treatment of traumatic brain injury .

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
