About this study

Official title: A Double-Blind, Randomized, Placebo-Controlled Trial of Artemisinin as an Add-on Therapy to Risperidone in the Treatment of Drug-Naive First-Episode Patients With Schizophrenia

This study will determine the effectiveness of artemisinin plus risperidone in improving symptoms and cognitive disturbances and in Chinese people with schizophrenia. The study addresses the Toxoplasma infection hypothesis of schizophrenia.

Read the detailed description

Evidences of high levels of Toxoplasma gondii antibodies in the serum and the cerebrospinal fluid (CSF) of individuals with schizophrenia have suggested that this organism might be involved in the etiopathogenesis of schizophrenia. The investigators hypothesize that antimicrobial therapy by using an add-on agent together with a well-proven neuroleptic may have favorable effects on a subgroup of schizophrenic patients.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Artemisinin in people with Schizophrenia, run by Beijing HuiLongGuan Hospital 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 5 inclusion and 9 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 12 Jul 2016. 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. 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 Positive and Negative Syndrome Scale (PANSS) (time frame: 10 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 12 Jul 2016.
