About this study

Official title: A Multiple-Center, Randomized, Double-Blind Study of Comparison of Paliperidone and Risperidone for Treatment of Patirnts With Methamphetamine-Associated Psychosis

Methamphetamine-associated psychosis (MAP) has been considered a pharmacological or environmental pathogen model of schizophrenia (SCZ) due in part to similarities in clinical presentation (i.e. paranoia, hallucinations, disorganized speech, and negative symptoms), response to treatment (e.g.neuroleptics),and pathologic mechanisms (e.g. central dopaminergic neurotransmission) of both conditions. Both paliperidone and risperidone are second generation antipsychotics,but have same pharmacological effects of antipsychotic treatment and paliperidone may have more efficacy and safty.This study was designed to examine the acute efficacy, safety, and tolerability of paliperidone and risperidone for patients with MAP.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing paliperidone and Risperidone in people with Methamphetamine Dependence, run by Wei Hao at 1 site in China.

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 5 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 4 Feb 2015. 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 China. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 severity of psychosis (time frame: up to 4 weeks. participants will be followed for the duration of hospital stay). 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 NCT01822730, 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 4 Feb 2015.
