About this study
Alcohol is one of most common harmful substance, and alcohol intake brings great burden on health worldwide. Excess alcohol intake may lead to alcohol-related brain injuries and cognitive impairment. Although both nerve growth factor and antioxidative treatment were effective to relieve alcohol-related injuries in central nervous system in the preclinical studies, there is no relevant clinical trial about their efficacy and safety on patients. Since nerve growth factor and one of the antioxidative medication, edaravone, have been used in some neural diseases in clinical trials, we tend to evaluate the efficacy and safety of nerve growth factor, or edaravone on alcohol-induced brain injuries. The study is a randomized-controlled study and the patients will be assigned into one of the following three groups randomly: (1) regular treatment (combination of vitamin B1, B6, C, E and mecobalamine) with nerve growth factor for 2 weeks and subsequently regular treatment for 6 months; (2) regular treatment (RT) with edaravone for 2 weeks and subsequently RT for 6 months; (3) RT alone for 6 months. The patients will be followed up for 6 months. Cognitive functions, recurrence of alcohol dependence, duration of abstention, alcohol intake, craving for alcohol and other psychological assessments will be recorded and compared among the 3 treatment groups and the efficacy of nerve growth factor or edaravone will be evaluated in our study.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Alcohol is one of most common harmful substance, and alcohol intake brings great burden on health worldwide. Excess alcohol intake may lead to alcohol-related brain injuries and cognitive impairment. Although both nerve growth factor and antioxidative treatment were effective to relieve alcohol-related injuries in central nervous system in the preclinical studies, there is no relevant clinical trial about their efficacy and safety on patients. Since nerve growth factor and one of the antioxidative medication, edaravone, have been used in some neural diseases in clinical trials, we tend to evaluate the efficacy and safety of nerve growth factor, or edaravone on alcohol-induced brain injuries. The study is a randomized-controlled study and the patients will be assigned into one of the following three groups randomly: (1) regular treatment (combination of vitamin B1, B6, C, E and mecobalamine) with nerve growth factor for 2 weeks and subsequently regular treatment for 6 months; (2) regular treatment (RT) with edaravone for 2 weeks and subsequently RT for 6 months; (3) RT alone for 6 months. The patients will be followed up for 6 months. Cognitive functions, recurrence of alcohol dependence, duration of abstention, alcohol intake, craving for alcohol and other psychological assessments will be recorded and compared among the 3 treatment groups and the efficacy of nerve growth factor or edaravone will be evaluated in our study.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Nerve Growth Factor, Edaravone and Combination of vitamin B1, B6, C, E and mecobalamine in people with Alcohol-induced Brain Injury, run by Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 27 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ying Peng, MD, PhD (+86-13380051581, pengy2@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Cognitive improvement (time frame: 2 weeks). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03968042, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Oct 2020; AzTrials last refreshed its copy on 7 Nov 2026.
