Pregnenolone Trial for Depression in Bipolar Disorders or Recurrent Major Depressive Disorder With Substance Abuse

The purpose of this research is to determine if pregnenolone supplement is associated with a reduction in substance use and craving in patients with recurrent major depressive disorder or bipolar disorder and substance abuse/dependence. This research also wants to explore if pregnenolone supplements are associated with improvement in psychiatric symptoms and memory, which are often negatively affected in these patients. It is hypothesized that patients receiving pregnenolone supplements would show greater improvements in mood symptoms and memory, and crave substances less than the patients receiving placebo.

About this study

Seventy five - (75) outpatients meeting the inclusion and exclusion criteria will be enrolled after completing an IRB-approved informed consent process. Baseline evaluation will include a medical and psychiatric history, structured clinical interview for DSM-IV (SCID), mood assessment with the Hamilton Rating Scale for Depression (HRSD, 17-item version), Inventory of Depressive Symptomatology-Self Report (IDS-SR) (Rush et al., 1996), Hamilton Rating Scale for Anxiety (HRSA), Young Mania Rating Scale (YMRS), and, and cognitive assessment with the Rey Auditory Verbal Learning Test (RAVLT), Stroop Test Color Trails, Wechsler Test of Adult Reading and the Brief Visual Memory Test-Revised (BVMT-R) will be performed. Substance use (days/week) of use, urine drug screens and time to relapse will be monitored. Craving for substances will be monitored with visual analogue scales. Pregnenolone or placebo will be initiated at one capsule/day (50 mg/d if active medication). Pregnenolone and the placebo will be obtained from Abrams Pharmacy, which has ensured the potency (the supplier uses GMP pharmaceutical standards). Participants will return for reassessment every 2 weeks for 8 weeks with the HRSD, IDS-SR, YMRS, ISS, and a neurocognitive battery (e.g. RAVLT, Stroop Test and Trails B). Side effects will be monitored with the PRD-III Somatic Symptom Scale (Thase et al., 1996). At week 4 subjects who not having significant side effects and have not had a 50% reduction in HRSD scores will have the dosage increased to two capsules per day (100 mg/d if active medication). Participants will be paid $30 at weeks 2, 4, and 8. Participants who respond favorably will, at completion, have the option of continuing this over-the-counter supplement if they so choose with their physician's knowledge and approval.

Primary outcomes

  1. For the primary outcome measure, we will analyze both between group differences in change from baseline but also response rates.

  2. Paired T tests will be used to compare outcome measures of HRSD, IDS-SR, HRSA, YMRS, RAVLT, Stroop, Trails B, and PRD III from baseline to exit.

  3. All participants returning for at least one post baseline assessment will be used.

  4. In the case of early withdrawal from the study, the last visit will be used for the exit scores (last observation carried forward).
