Summary
The goal of this clinical trial is to compare pregnenolone and placebo (a placebo is a
look-alike substance that contains no active drug) in Operation Enduring Freedom/Operation
Iraqi Freedom/Operation New Dawn (OEF/OIF/OND)-Era Veterans with a history of chronic
Traumatic Brain Injury (TBI). The main questions it aims to answer are:
- Does pregnenolone improve psychological health, overall physical function, cognition,
symptoms of PTSD, and pain more than placebo over the 8-week study period, and what is
the most effective dose of the drug that is safe and well-tolerated?
- What are the biological effects of pregnenolone, and how do pregnenolone and other
molecules change over the course of treatment? (and do pregnenolone and other molecules
predict clinical improvement?)
Participants who are eligible and consent to participate in the study will:
- be randomized in a 1:1 ratio to take pregnenolone or placebo
- be given pregnenolone or placebo to take each day at home
- will participate in 6 visits over 11 weeks for tests, exams and procedures that are for
study purposes (each visit will last 1.5 - 3 hours)
- be evaluated at each visit to determine if there are any bad reactions to the study drug
and if study participation is still appropriate
- be financially compensated for their visit time and travel cost
