What this research studies

You would be randomly assigned to one of three groups: one neurosteroid, the other neurosteroid, or a placebo, and neither you nor the staff would know which you get. The trial is double-blind and uses an adaptive design that can adjust group assignments as results come in to focus on the best options. Doctors will monitor your pain levels, side effects, and overall safety over the treatment period and collect health information and possibly blood samples. The work builds on earlier findings that one neurosteroid (pregnenolone) helped chronic low back pain and that another (DHEA) shows promise.

Who could benefit from this research

Good fit: Ideal candidates are U.S. military veterans with persistent chronic low back pain who meet the trial's medical and safety criteria and can attend clinic visits at the study site.

Not a fit: People without chronic low back pain, with pain caused by conditions not targeted in the trial, or with medical contraindications to neurosteroids may not benefit from this research.

Why it matters

Potential benefit: If successful, this could offer veterans a safer, non-addictive medication option to reduce chronic low back pain.

How similar studies have performed: Prior randomized work reported that pregnenolone at a high dose reduced chronic low back pain, and early data for DHEA are promising, but larger trials are still needed.
