About this study

Official title: Randomized, Double-blind, Parallel Trial Comparing the Effects of Eltoprazine (Adjunct to Anti-psychotics) With Placebo in Adults With Schizophrenia, in Improving One or More Dimensions of Cognitive Impairment Associated With Schizophrenia

The purpose of this study is to determine if eltoprazine (as an adjunct to anti-psychotic medication) improves one or more aspects of cognitive impairment in adult schizophrenic patients.

Read the detailed description

Schizophrenia is a common and highly disabling psychiatric disorder with population prevalence around 1%. The manifestations of schizophrenia fall into three major domains: 1) "positive" symptoms, such as delusions, hallucinations, and disorganization of behavior; 2) "negative symptoms," including social withdrawal, lack of motivation, and reduced expression of affect; and 3) cognitive dysfunction. Cognitive deficits are seen in most patients with schizophrenia.

Eltoprazine has agonist effects on both 5-HT1A and 5-HT1B receptors, which suggests that this drug may be useful for normalizing prefrontal cognitive abilities, reducing aggression and impulsivity, and improving cognitive function in schizophrenia.

This study will compare the effects of Eltoprazine (as an adjunctive treatment to anti-psychotics) with Placebo in Adults with a DSM IV/DSM IV TR diagnosis of schizophrenia, in potentially improving one or more dimensions of cognitive impairment associated with schizophrenia.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Eltoprazine in people with Cognitive Impairment and Schizophrenia, run by Amarantus BioScience Holdings, Inc. at 6 sites 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 12 inclusion and 13 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 14 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites 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. 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 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.

What does the primary outcome measure?

MATRICS Consensus Cognitive Battery (MCCB) (time frame: At Baseline and every 4 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 14 Apr 2015.
