A Phase 4 study testing Olanzapine, Amisulpride and Risperidone in people with Schizophrenia and Schizophrenia and Disorders With Psychotic Features, run by Technical University of Munich at 1 site in Germany.
Trial summary
The main objective of the trial is to evaluate, how long an antipsychotic relapse-prevention should be continued and to which time a patient with schizophrenia is protected enough, so that a withdrawal or reduction of the medication seems appropriate. Relapse is defined as primary outcome. Read more about this study

Read the detailed description
The main objective of the trial is to evaluate for the first time, how long an antipsychotic relapse-prevention should be continued and to which time a patient is protected enough, so that a guided withdrawal or reduction of the medication seems appropriate. Relapse is defined as primary outcome. We include patients with schizophrenia or schizoaffective disorder in remission for at least 3 years under a stable antipsychotic medication.

| Study group | Role | What they receive |
|---|---|---|
| Intervention | Experimental | Intervention group: guided discontinuation or dose-reduction of the current antipsychotic medication. The antipsychotic drug used before study start will be discontinued gradually under medical surveillance. The process of discontinuation depends on the physicians judgement und should be guided be the participants needs and clinical status. This approach was already used before in another study ("gradual discontinuation", Wunderink et al., 2007). We assume that the dose can be reduced by approximately 1/6 of the starting dose every two weeks. If long acting antipsychotics are applied, there is no need for a gradual discontinuation due to their long half life. Receives: Drug: Olanzapine; Drug: Amisulpride; Drug: Risperidone; Drug: Haloperidol; Drug: Quetiapine; Drug: Perphenazine; Drug: Sulpiride; Drug: bromperidol; Drug: Zuclopenthixol; Drug: Thioridazine; Drug: Paliperidone; Drug: Ziprasidone; Drug: Benperidol; Drug: Fluspirilene; Drug: Pimozide; Drug: Perazine; Drug: Fluphenazine; Drug: Flupentixole; Drug: Sertindole |
| Control | Active comparator | The participants receive the same antipsychotic drugs, they have received before the start of the study, without changing the dose or the application form. Study medication is, with exception of Clozapin, every oral or depot neuroleptic drug approved for the treatment of schizophrenia in Germany.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Olanzapine, Amisulpride and Risperidone in people with Schizophrenia and Schizophrenia and Disorders With Psychotic Features, run by Technical University of Munich at 1 site in Germany.
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 8 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 11 Oct 2018. 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 Germany. 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?
Relapse (time frame: Every 2 weeks up to 26 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 11 Oct 2018.
