About

Participants will be randomized to either Mifepristone 600mg once daily for seven days or Placebo tablet once daily for seven days. Rating scales, vital signs, cortisol levels will be collected for evaluation.

Full description

Mifepristone is an antagonist of type II glucocorticoid (GR-II) receptors, which has shown safety, efficacy, and good tolerability in the treatment of psychotic major depression (PMD). Like BPD, Hypothalamic-pituitary-adrenal (HPA) axis hyper-responsiveness appears to play a role in PMD pathophysiology. Belanoff et al. (2002) hypothesized that mifepristone causes a normalizing "resetting" of HPA axis rhythm, accounting for its efficacy in PMD. Mifepristone produces a marked (2- to 3- fold) compensatory increase in central cortisol levels via its antagonism of GR-II receptors. This consequent central cortisol elevation may then be able to counteract abnormally heightened corticotrophin-releasing hormone (CRH) activity via enhanced negative feedback mechanisms.

This is a proof of principle study of mifepristone in the treatment of individuals with BPD and histories of childhood abuse, which aims to translate neurobiological research concerning HPA axis abnormalities in BPD into a novel clinical intervention for patients. This project will also explore an innovative approach to the structure of pharmacotherapy for BPD. Specifically, we will employ the circumscribed (finite) drug administration period used in prior studies of mifepristone in neuropsychiatric illness, which differs from the current clinical practice of indefinite daily usage of medications. We hypothesize that mifepristone will beneficially impact stress response neurobiology and consequently ameliorate associated BPD symptoms.

Inclusion criteria

18-64 years of age at study entry
Female or Male
Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) diagnosis of borderline personality disorder (confirmed by SCID II) with history of abuse prior to the age of 18.
Able to provide informed consent
Inpatient or outpatient
Clinical stability as defined by:
- Subjects must not have experienced an exacerbation of their illness within 4 weeks prior to randomization, leading to an intensification of psychiatric care in the opinion of the principal investigator. Examples of intensification of care include, but are not limited to: inpatient hospitalization, day/partial hospitalization, outpatient crisis management, or psychiatric treatment in an emergency room AND
- Psychotropic treatment stability for at least 2 weeks prior to randomization (no change in dosing or addition of any new psychotropic medication)
Female subjects of childbearing potential must test negative for pregnancy at screening visit and agree to use the double-barrier method, as defined by 2 physical barriers such as a condom, diaphragm, or cervical occlusive cap, coupled with an additional barrier such as spermicidal foam, gel, film, cream or suppository for the duration of the study. Subjects having undergone a hysterectomy or bilateral oophorectomy or other form of female sterilization or patients having been medically confirmed to be post-menopausal, would not require any other method of contraception.
Minimum severity of a total score > 3 on the The Clinical Global Impression severity (CGI-S)
Must agree not to consume tonic water and grapefruit or grapefruit product for 3 days prior to beginning medication and until the final study visit

Exclusion criteria
