About this study
Official title: Magnesium Sulfate for Neuroprotection After Brain Trauma
The purpose of the study is to determine whether magnesium sulfate, given within 8 hours of a moderate or severe traumatic brain injury improves survival, decreases the number of people developing seizures, improves the survivors' mental and psychological functioning, including the ability to return to daily life, live independently, and return to work or school.
Read the detailed description
The purpose of the study is to determine if treating head-injured patients with magnesium sulfate will improve medical, mental, and psychological recovery. In particular, the study will assess each patient's ability to return to daily life, live independently, and return to work or school as done before the head injury occurred. The study will also assess magnesium sulfate's ability to reduce the risk of developing seizures (epilepsy) as well as to improve survival rates after a traumatic brain injury. Patients on the study are assigned randomly (by chance) to either the magnesium sulfate group or the group which gets a placebo. This means they have an equal chance of being in either group. Before the first dose is given, two teaspoons worth of blood are drawn from a vein in the arm. The first dose of magnesium sulfate is 1meq/kg given intravenously within 8 hours of injury. Then a five day continuous intravenous infusion of magnesium sulfate 0.24meq/kg per hour is begun. Daily magnesium levels are checked and the dose changed in order to keep the Magnesium blood level at approximately 4meq/L. If the person does not receive magnesium sulfate, he receives a placebo which looks just like magnesium sulfate but contains no active medication. If the person leaves the hospital before the five days are over, the magnesium or placebo is stopped. Patients on the study will receive a brief exam in person or over the phone at one and three months after the injury to determine whether they have had any seizures and to evaluate how they are functioning and recovering from their head injury. Each evaluation will last about one hour. At six months after the injury, they will have full neuropsychological and psychosocial evaluations done at Harborview. These tests will take about five hours to complete and include tests of vocabulary, problem solving, and coordination. There will be questions about how the injury has affected the way they feel and interact socially. For example, there will be questions about their ability to work, manage personal affairs, what their moods are like, and how anger is handled.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing magnesium sulfate in people with Brain Injuries and Head Injury, run by University of Washington at 1 site in United States.
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 1 inclusion and 6 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: finished, as of the sponsor's last update on 28 Oct 2011. 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 United States. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00004730, 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.
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 28 Oct 2011.
