Trial summary

The primary objective of this study is to demonstrate the bioequivalence, with respect to risperidone and its active moiety, of a single oral dose of risperidone given as a 4 mg orally-disintegrating tablet and as a 4 mg conventional RISPERDAL tablet. In addition, their tolerability and safety will be documented. Read more about this study

About this study

Official title: A Bioequivalence Study Comparing a Single Oral Intake of a 4mg Orally-disintegrating Tablet With a 4mg Conventional Risperdal Tablet in Patients With Schizophrenia

The primary objective of this study is to demonstrate the bioequivalence, with respect to risperidone and its active moiety, of a single oral dose of risperidone given as a 4 mg orally-disintegrating tablet and as a 4 mg conventional RISPERDAL tablet. In addition, their tolerability and safety will be documented.

Read the detailed description

This is a single-center, open, randomized, 2-way crossover bioequivalence study in 40 subjects with schizophrenia or schizoaffective disorder. The study will consist of 2 treatment periods, 5 days per period. The subjects will receive a single 4 mg RISPERDAL conventional tablet in period 1 and a single 4 mg orally-disintegrating tablet in period 2; or the orally disintegrating tablet in period 1 and conventional tablet in period 2. A washout period of at least 10 days between Day 1 of Period 1 and Day 1 of Period 2 will separate the 2 treatments. In both treatment periods plasma concentrations of the drug will be measured. Serial blood collections will be made beginning at 0 hour (immediately before study drug administration) and continuing up to 96 hours after study drug administration in each period. Safety will be evaluated throughout the study using physical examinations, electrocardiogram recordings (ECG), clinical laboratory testing (hematology, serum chemistry, urinalysis), vital signs measurements, pregnancy testing, drug screening, and monitoring of adverse events. The study will be approximately 6 weeks long (including the screening period). Subjects will enter the study facility 3 days before the first administration of study medication on Day 1 of the first period. They will remain at the facility until all study-related procedures are completed on Day 5 of the second study period, a period of approximately 18 days. 4 mg risperidone (either conventional tablet or orally-disintegrating tablet), single dose, oral intake

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing risperidone in people with Schizophrenia and Schizoaffective Disorders, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..

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 7 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 26 Apr 2010. Status can change between updates, so confirm with the study contact before making plans.

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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

PK parameters (Cmax and AUC) for active moiety, 9-OH-risperidone and risperidone. 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 26 Apr 2010; AzTrials last refreshed its copy on 30 Oct 2026.
