Angiotensin (1-7) for Traumatic Brain Injury (ANGel T Trial)

Phase 1 & 2
Recruiting
Led By Bellal Joseph, MD
Research Sponsored by University of Arizona
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Moderate or severe traumatic brain injury (TBI) defined as Glasgow Coma Scale (GCS) score on trauma presentation of 12 or less. In general: Moderate TBI will be defined as loss of consciousness between 30 minutes and 24 hours and GCS between 9 and 12. Severe TBI will be defined as loss of consciousness > 24 hours and GCS ≤ 9.
Age 18 years or older at time of enrollment.
Timeline
Screening 3 weeks
Treatment Varies
Follow Up enrollment to 21 days, enrollment to 90 days

Summary

This trial aims to test the safety and effectiveness of the drug Angiotensin (1-7) in treating people with moderate to severe traumatic brain injury (TBI). Participants will receive a once

Who is the study for?
This trial is for adults who've had a moderate to severe traumatic brain injury (TBI) with a Glasgow Coma Scale score of 12 or less. They must be enrolled within 48 hours of the injury and have a CT scan confirming an acute intracranial lesion. Consent from the participant or representative is required.
What is being tested?
The trial tests Angiotensin (1-7)'s safety and effectiveness in improving mental function and reducing physical signs of TBI damage. It involves daily injections for 21 days, blood samples, two MRI scans, tasks, and questionnaires to assess brain function.
What are the potential side effects?
Potential side effects are not specified but will be monitored through health assessments during treatment with Angiotensin (1-7), comparing it against a saline placebo.
