Chronic pain symptoms are very common among U.S. Military Veterans and have a profound negative impact on mental health symptoms and quality of life, in addition to increasing risk for suicidal ideation and suicidal behaviors. There are currently extremely few safe and effective pharmacological treatments for chronic pain disorders, and the clinical need to develop new therapeutics for pain has never been more urgent. Fueled by the worsening opioid crisis and further exacerbated by the COVID-19 pandemic, opioid and other drug overdose deaths have climbed to staggeringly high levels. The rapid development of medications for the management of chronic pain conditions that are safe, well-tolerated, efficacious and non-addicting is thus of paramount importance. The two neurosteroid candidates to be investigated in this trial are naturally occurring molecules enriched in human brain and potentially ideal candidates for safe and effective chronic pain treatment.
Veterans, 18-65 years of age with chronic low back pain.
Based on medical history and medical records, have low back pain (Thoracic Vertebrae 6 or below) present on most days for the preceding 6 months or longer, and fulfill all disease diagnostic criteria (please see disease diagnostic criteria below).
Have a weekly mean of 24-hour average pain score 4 at baseline.
Negative pregnancy test if female. Sexually active subjects are required to use a medically acceptable form of birth control if they are of childbearing potential and could become pregnant during the study. A medically acceptable form of birth control includes non-hormonal intrauterine devices, surgical sterilization, or double barrier methods (e.g. diaphragm with contraceptive jelly, condom with contraceptive foam, cervical caps with contraceptive jelly). Sexual abstinence with agreement to continue abstinence or to use a medically acceptable method of contraception (as listed above) should sexual activity occur is permissible.
Unstable medical or neurological illness, including seizures, renal impairment or cerebral vascular accident (CVA).
Use of oral contraceptives or other hormonal supplements-this is out of caution, as it is unknown if the study medications would impact the efficacy of hormonal contraception.
Significant suicidal or homicidal ideation that necessitates intervention.
Daily use of long or short-acting narcotic medications (PRN use will be considered).
