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

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.
