  • Score of 15 or greater on the HAM-D (17) at the end of the baseline period(s) (i.e., at randomization no more than 20% less than entry enrollment criteria).

Who cannot join

  • Patients will be excluded from the study if they meet any of the following criteria:
  • Women who are pregnant, intending to become pregnant in the next month or breast-feeding.
  • Treatment with any of the following therapies within the specified interval prior to baseline: Fluoxetine - 4 weeks; Investigational compounds 4 weeks; MAOIs 1 week; Other antidepressants 1 week.
  • Contraindication or history of hypersensitivity to mifepristone as well as cortisol, and CRH.
  • Clinically significant organ system disease where mifepristone would be contraindicated or interfere with medical treatment.
  • Have evidence of any disorder that represents a contraindication to the use of mifepristone (such as adrenal disease or a condition requiring chronic corticosteroid administration).
Show all 22Show fewer
  • History of Addison's Disease, Cushing's Disease, insulin dependent diabetes, or other uncompensated endocrine conditions.
  • Evidence of infection, severe liver, respiratory, or renal disease.
  • Have clinically significant cardiovascular disease, e.g., angina, valve disease, arrhythmia, cardiac failure.
  • Anemia (hemoglobin less than 10 g/dL or hematocrit less than 30%)
  • Have a known clotting defect or are receiving anticoagulants.
  • Rapid cycling in the last year (defined as greater than 6 episodes).
  • History of porphyrias.
  • Clinically significant abnormalities in physical exam, ECG, or laboratory assessments.
  • History of any disease which, in the investigator's opinion may confound the results of the study or pose an additional risk, including but not limited to, history of organic mental disorder, seizures, or mental retardation.
  • Substance dependence that is not in sustained full remission (DSM-IV definition)
  • Other principal psychiatric diagnosis judged by the investigator to dominate the clinical presentation. In particular, patients with depressive symptoms more than 2 years in duration should be carefully evaluated to determine whether another psychiatric diagnosis exists which could interfere with efficacy and safety measurements.
  • History of nonresponse to greater than four trials of antidepressants for the current episode (not including mood stabilizers) will exclude subjects.
  • Known hypersensitivity to CRH, hydrocortisone, metyrapone, or mifepristone.
  • Women who are pregnant or breast-feeding.
  • Clinically significant organ system disease where mifepristone would be contraindicated or interfere with medical treatment.
  • History of prophyrias.

About this study

Official title: Antiglucocorticoid Therapy in Bipolar Depression With Mifepristone (RU486)

Bipolar Depression is a severe illness with high rates of psychiatric comorbidity and increased mortality related to suicide and medical illness. Hypothalamic pituitary axis (HPA) hyperactivity are found in bipolar disorder related to depression and mixed states. Patients with bipolar disorder also have cognitive difficulties and endocrine disturbances may contribute to such dysfunction. Antiglucorticoid therapies are novel treatments of mood disorder. Preliminary data in psychotic depression suggesting that mifepristone (RU-486), a glucocorticoid receptor antagonist, has antidepressant and salutary cognitive effects in a matter of days. In this study we examine the effects of mifepristone in severe bipolar depression in a parallel, double blind placebo controlled experiment. Bipolar subjects maintained on either lithium or valproate, after washout or prior antidepressants have a detailed neuroendocrine assessment. Patients approximately or almost 75 will receive eight days of mifepristone versus placebo after which patients are blindly crossed over to the opposite arm. Patients and a group of matched controls approximately or almost 35 will be compared with neuroendocrine, cognitive, and neurophysiologic testing to fully characterize their phenotype and explore biomarkers of response. It is hypothesized that stigmata of HPA axis hyperactivity and cognitive impairment will be predictive of response to antiglucocorticoid therapy with mifepristone.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Mifepristone in people with Bipolar Disorder, run by National Institute of Mental Health (NIMH) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00043654, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jul 2017.
