Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who have suffered a moderate to severe TBI within 48 hours of enrollment.

Probably not a fit

Patients with a history of neurodegenerative diseases or recent neurosurgery may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to evaluate the safety and efficacy of Angiotensin (1-7) in individuals who have experienced moderate to severe traumatic brain injury (TBI). Participants will receive daily injections of the drug for 21 days, undergo MRI scans, and complete cognitive assessments to measure improvements in mental functioning and physical signs of brain damage. The study will compare two different doses of Angiotensin (1-7) against a placebo to determine its effectiveness and safety profile.

Why it matters

Potential benefit: If successful, this treatment could improve cognitive recovery and overall outcomes for patients with traumatic brain injuries.

How similar studies have gone: While the use of Angiotensin (1-7) in this context is novel, similar studies targeting the renin-angiotensin system have shown promise in other conditions.

* Enrollment within 48 hours of TBI.

Exclusion Criteria:

* Time of injury cannot be determined.
* Neurosurgery within the last 30 days.
* History of neurodegenerative disease or disorder including dementia, Parkinson's disease, multiple sclerosis, seizure disorder, or brain tumors that would impact cognitive testing.
