Major Depressive DisorderPhase 3NCT00146523
An International Study of the Safety and Tolerability of Corlux for Psychotic Symptoms in Psychotic Major Depression
A Phase 3 study testing Mifepristone in people with Major Depressive Disorder, run by Corcept Therapeutics at 19 sites in 4 countries.
Trial summary
Corlux (mifepristone) is a new medication that modulates the body's use of a hormone called cortisol. Under normal conditions, cortisol and other hormones are created by the body in response to physical and emotional stress, triggering a healthy stress response. Read more about this study

About this study
Official title: An International, Double-Blind, Placebo-Controlled, Study of the Efficacy and Safety of CORLUX™ (Mifepristone) vs. Placebo in the Treatment of Psychotic Symptoms in Patients With Psychotic Major Depression (PMD)
Corlux (mifepristone) is a new medication that modulates the body's use of a hormone called cortisol. Under normal conditions, cortisol and other hormones are created by the body in response to physical and emotional stress, triggering a healthy stress response. People who suffer from psychotic major depression may have unusually high levels of cortisol circulating within them or abnormal patterns of cortisol levels, overloading the stress response mechanism and causing symptoms of psychosis such as delusional thoughts or hallucinations. If Corlux can keep the body's cortisol receptors from being overloaded, the stress response system may return to normal function, which may result in improvement of symptoms. The purpose of this 56 day study is to learn the safety and effectiveness of Corlux in patients who have been diagnosed with psychotic major depression (PMD).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Mifepristone in people with Major Depressive Disorder, run by Corcept Therapeutics at 19 sites in 4 countries.
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 3 inclusion and 3 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 15 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 19 sites in Croatia, Serbia and Montenegro, Bulgaria, Romania. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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.
What does the primary outcome measure?
The change in a measure of psychosis (time frame: screening and on Days 0, 7, 14, 28, 42, and 56). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00146523, which also lists 4 linked publications.
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 15 Feb 2012; AzTrials last refreshed its copy on 8 Nov 2026.
