About this study

Official title: Glibenclamide in Aneurysmatic Subarachnoid Hemorrhage: A Prospective and Randomized Study

A randomized, double-blind and prospective trial meant to evaluate the use of Glibenclamide on acute aneurysmatic subarachnoid hemorrhage. Patients will allocated randomly in two groups, one for 05 mg daily intake of glibenclamide for 21 days and another for control with placebo. General clinical data and late cognitive status will be accessed in both groups.

Read the detailed description

GASH is a double blind, prospective and randomized clinical trial centered on the University of Sao Paulo General Hospital. Patients will be recruited from neurological/neurosurgical intensive care units. Appropriate ethics and regulatory approvals will be sought for all subjects, according to the International Conference on Harmonization guidelines for good clinical practice (ICH GCP). Investigators will obtain informed written consent from all patients or their legal representative. Recruitment will take place between 2018 and 2019.

Patients will be randomly assigned (1:1) to receive either glibenclamide 5mg or placebo. Coded boxes containing either 21 similar tablets of glibenclamide 5mg or placebo will be assigned a number. A computer-generated randomization code will be used to randomize patients by blocks of ten (five glibenclamide, five placebo). Each box will be identified by a code number specific and subsequently selected for distribution in ascending numerical order. Patients will start treatment as soon as possible within 96 h of the ictus, with a daily dose till the 21° day after the bleed. Trial medication consisted of one tablet a day, given orally or via a nasogastric tube. Aneurysm treatment, either by microsurgery or embolization, will be performed as soon as possible, according with the standard of care for the recruiting center. Nimodipine 60mg, every four hours, will be started on admission and continued till the 21° day after the ictus, in all patients as standard of care.

Patient's demographics, medical history and relevant investigation results will be collected. The severity of the hemorrhage will be clinically assessed by World Federation of Neurosurgical Societies grading scale and radiologically using the modified Fischer scale. At 6 months of follow up patients will be interviewed with modified Rankin scale (mRS) questionnaire (a scale that measures degree of incapacity/ dependence and mortality after neurological events) by a nurse or a physician with no knowledge of treatment allocation. Psychologists will evaluate quality of life and cognitive performance using the "short-form health survey questionnaire" (SF-36) and neuropsychological tests. The main hypothesis is that, once compared with standard of care, glibenclamide 5mg will provide better clinical outcome and additionally will decrease mortality and improve quality of life and cognitive performance after 6 months.

Sample size: It was estimated the sample size of 50 randomized patients to give 90% power at the 5% significance level (two-sided) to detect a treatment effect equivalent to an absolute increase of 7% in the proportion of patients with a favorable outcome (30-day mortality rate after subarachnoid hemorrhage approaches 50% and 25% of survivors present some degree of neurological morbidity25). This calculation was based on an ordinal analysis of the 6-month mRS (the primary outcome) assuming that the treatment effect follows a proportional odds model.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Modified Rankin Scale (early)

    Evaluate patients life quality and morbidity, from 1 to 6 ('no symptoms' to 'Death')

    Measured: To be measured on the 21th day of medication/control, when happens the end of intervention

  2. Short-Form Healthy Survey Questionnaire (SF-36)

    Cognitive assessment and quality of Life measured by 11 questions that leads to a quantification scale called Raw Scale (RS). The RS identify 8 domains with a calculable score from 0 (worst) to 100 (best): Functional capacity; Limitation by physical aspects; Pain; General health; Vitality; Social aspects; Emotional aspects and Mental health.

    Measured: To be executed 6 months after the end of intervention

  3. Modified Rankin Scale (late)

    Evaluate patients life quality and morbidity, from 1 to 6 ('no symptoms' to 'Death')

    Measured: To be measured 6 months after the end of intervention and compared with the early result

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Glibenclamide in people with Subarachnoid Hemorrhage, Aneurysmal, run by University of Sao Paulo General Hospital at 1 site in Brazil.

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 2 inclusion and 8 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 26 Jun 2018. 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 Brazil. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

What does the primary outcome measure?

Modified Rankin Scale (early) (time frame: To be measured on the 21th day of medication/control, when happens the end of intervention). The study lists 3 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 NCT03569540, which also lists 1 linked publication.

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.
