Brief Summary

Anxiety and depression symptoms occur at high rates in Veteran populations and can significantly impact function, compromising the ability to work and to successfully form and maintain valued relationships. Several other symptoms commonly occur with anxiety and depression, including poor sleep quality and chronic pain. Since all these symptoms frequently occur together, they may have a common underlying biological basis. A single medication that could effectively treat all these symptoms would be ideal. Converging data suggest that pregnenolone is a promising pharmacological agent for treating multiple psychiatric symptoms and functional impairment. The investigators thus propose to conduct a clinical trial of pregnenolone in Veterans with anxiety and depression symptoms. Pregnenolone has minimal side effects, and the prior research demonstrates that pregnenolone is well-tolerated by Veterans. Treatment with pregnenolone could thus be an efficacious new therapeutic for Veterans experiencing depression, anxiety, poor sleep quality and chronic pain conditions.

Outcome Measures

Primary Outcomes (1)

  • The World Health Organization disability assessment schedule II (WHODAS-2)

    The WHODAS-II is an instrument developed by the World Health Organization to assess behavioral limitations and restrictions regarding participation in specific activity domains experienced by an individual independent of their medical diagnosis. The conceptual frame of reference of this instrument is the International Classification of Functioning, Disability, and Health (ICF). Specifically, the instrument is a 36-item, generic, multidimensional questionnaire designed to evaluate the functioning of the individual in six activity domains (i.e., understanding and communicating, getting around, self-care, getting along with people, life activities, and participation in society). The 12-item WHODAS 2.0 score range from 12 to 60, where higher scores indicate higher disability or loss of function.

    Change from baseline at 10 weeks

Secondary Outcomes (3)

  • Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS)

    Change from baseline at 10 weeks

  • Brief Pain Inventory, Second Edition (BPI-II)

  • Pittsburgh Sleep Quality Index (PSQI)

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Veterans enrolled for care at the Durham VAHCS
  • Veterans who score a minimum score of 20 or higher (moderate symptoms) on the PHQ-ADS (Kroenke et al 2017)
  • Oral pregnenolone could reduce the effectiveness of oral contraceptives, thus women will be required to use a medically and study-approved contraceptive or otherwise not be of child-bearing potential. Birth control methods must be non-hormonal
  • No anticipated need to alter psychiatric medications for duration of study involvement
  • Ability to participate fully in the informed consent process

You may not qualify if:

  • History of allergy to PREG
  • Medical disorders that may preclude safe administration of PREG or exacerbate mental or physical health symptoms
  • PTSD diagnosis, as per the PCL-5, scores of 38 or higher
  • Current suicidal or homicidal ideation necessitating clinical intervention or representing an imminent concern
  • Prior attempts or suicidal ideation that does not require clinical intervention or represent an imminent concern is permitted
  • Serious unstable medical illness, such as history of cerebrovascular accident, prostate, uterine or breast cancer, others (at the discretion of the PI and medical oversight team)
  • Benzodiazepine or opioid use
  • Current diagnosis of bipolar disorder, schizophrenia or other psychotic disorder, or cognitive disorder due to a general medical condition other than mild TBI (assessed at screening)
  • Initiation or change in psychotherapy within 3 months of randomization (i.e., psychotherapy must be stable for 3 months prior to study start
  • Due to lack of safety data in pregnant and breast-feeding women, female participants who are pregnant or breast-feeding will be excluded
  • As indicated by the DSM-5, moderate or severe Substance Use Disorders (excluding caffeine and tobacco) within 1 month of study entry
