Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 55 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • Subjects will meet DSM-IV diagnostic criteria for schizophreniform disorder, schizophrenia, schizoaffective disorder or (non-affective) psychotic disorder, NOS. Subjects with schizophreniform disorder or psychotic disorder, NOS, will be diagnostically reevaluated (recontacted if no longer involved in the study) after a minimum of six months of psychotic symptoms in order to determine whether diagnostic criteria for schizophrenia or schizoaffective disorder have been met.
  • Subjects will be between 18 and 55 years of age, inclusive.
  • Subjects will be able to fully participate in the informed consent process, or have a legal guardian able to participate in the informed consent process.
  • Present score on at least one PANSS psychosis items (P1, P2, P3, P5 or P6) > 4(moderately severe) and CGI Severity score > 4 (moderate).
  • Female patients of childbearing potential must be using a medically accepted means of contraception

Who cannot join

  • Current active substance use disorder diagnosis or a history of cocaine abuse or dependence;
  • Female patients who are either pregnant or nursing;
  • Known history of mental retardation, seizure disorder, or a clinically significant head injury (prolonged loss of consciousness, neurological sequelae, or demonstrated structural brain injury);
  • Non-English speaking (mastery of English insufficient to participate in study evaluation procedures);
  • Serious, unstable medical illness;
  • Known hypersensitivity to any study medication;
Show all 11Show fewer
  • Medical contraindication to any element of the study procedure;
  • Current symptoms which present serious risk of danger to self or others;
  • Participation in a clinical trial of an investigational drug within 30 days of study entry;
  • Current severity of psychiatric symptoms contraindicates a delay in initiation of antipsychotic medication treatment until functional imaging studies and neuropsychological testing have been completed;
  • Baseline QTc interval of > 450 msec.

About this study

Official title: A Randomized Double-blind Trial of Aripiprazole and Risperidone in Schizophrenia: An Evaluation of Neuroimaging, Neuropsychological, and Pharmacogenomic Markers of Differential Treatment Response

This study is being conducted to find a way to predict how individual schizophrenic patients will respond if they are treated with different types of antipsychotic drugs. This could help doctors prescribe the medication that will work best for each individual.

Read the detailed description

The primary objective of the proposed research project is to identify a practical method of predicting differential antipsychotic drug treatment response in patients with schizophrenia. In particular, we will examine differential response to two antipsychotic drugs, aripiprazole and risperidone, that have contrasting pharmacologic activity at D2-type dopamine receptors, i.e., partial agonism vs. antagonism, respectively. A number of candidate predictors will be examined, including neuroimaging parameters (regional neuroanatomical and metabolic variations, fallypride binding to D2-like receptors), neuropsychological testing, clinical features, laboratory measures, and genetic studies.

Secondary objectives include: (1) extension of our previous efforts to characterize abnormalities in cortico-striato-thalamic circuits in unmedicated schizophrenics using PET and MR imaging; and, (2) examination of the role of omega-3 fatty acid activity in schizophrenics as a predictor of dopaminergic activity.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AripiprazoleDrug

    Also called Abilify

    Target dose = 15mg by mouth per day for 16 weeks. The dosage will be titrated in accordance with the treating physician's clinical judgment, generally reaching full dosage within one week of initiation. The dosage may be increased as clinically indicated, by the treating physician. Any deviation from these target dosing schedules must be reviewed and approved by the principal investigator, generally prior to the adjustment unless clinical circumstances require more immediate adjustment (in which case the treating physician should consult with the principal investigator as soon as is practically possible).

  • RisperidoneDrug

    Also called Risperdal

    Target Dose = 2mg by mouth per day for 16 weeks. The dosage will be titrated in accordance with the treating physician's clinical judgment, generally reaching full dosage within one week of initiation. The dosage may be increased as clinically indicated, by the treating physician. Any deviation from these target dosing schedules must be reviewed and approved by the principal investigator, generally prior to the adjustment unless clinical circumstances require more immediate adjustment (in which case the treating physician should consult with the principal investigator as soon as is practically possible).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pre and Post Treatment PET and MRI Imaging

    Measured: At baseline and 16 weeks

  2. QTc Measurement

    Information regarding the Outcome Measure being a Primary or Secondary, is unavailable.

Secondary outcomes (1)
  1. Assessment of Pretreatment and Posttreatment Psychiatric Rating Scales to Include PANSS and CGI

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Aripiprazole and Risperidone in people with Schizophrenia, run by Kettering Health Network at 1 site 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 5 inclusion and 11 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: stopped early, as of the sponsor's last update on 28 Jul 2020. 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 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. 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?

Yes. Results are posted in the registry (first posted 14 Dec 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Pre and Post Treatment PET and MRI Imaging (time frame: At baseline and 16 weeks). The study lists 2 primary outcomes in all. 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 28 Jul 2020.
