About this study

Official title: The Efficacy and Safety of Risperidone in Adolescents With Schizophrenia: a Comparison of Two Dose Ranges of Risperidone

A clinical study to compare the safety and effectiveness of two different dose ranges of risperidone solution in the treatment of adolescents with a diagnosis of schizophrenia.

Read the detailed description

This is a clinical study of an investigational drug called risperidone in the treatment of schizophrenia in adolescents. Initially children (age 2 to 12 yrs) and schizophreniform subjects were also allowed but excluded following protocol amendment.

The study will include approximately 260 patients aged 13 to 17 years with a diagnosis of schizophrenia. Subjects will be randomly assigned to one of two groups on enrollment and will be given risperidone as an oral solution each day for 8 weeks at doses within one of two dose different ranges, according to the assigned study group.

Initially the two dose range were 0.15-0.4 mg/day and 1.5-4mg/day but were changed in protocol amendment to evaluate the maximum tolerated dose with a minimum of 3.5mg/day and maximum of 6mg/day (resp. 0.35 and 0.6mg/day in low dose treatment arm) Risperidone lower dose (0.35-0.6 mg/day [subjects >=50kg] or 0.007-0.012 mg/kg/day [subjects <50 kg]) as 0.1 mg/mL oral solution or risperidone higher dose (3.5-6 mg/day [subjects >=50 kg] or 0.07-0.12 mg/kg/day [subjects <50 kg]) as 1 mg/mL oral solution for 8 weeks. Daily dose can be given all at once or through 2 administrations (in morning and evening); the dose is increased based on efficacy and tolerability.

What participants receive

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

What is being measured

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

  1. Change in total PANSS (Positive and Negative Syndrome Scale for Schizophrenia) from baseline to the 8-week endpoint

Secondary outcomes (1)
  1. Change from baseline in PANSS subscale scores and Clinical Global Impression (CGI-S and CGI-I) scores, number of subjects achieving a clinical response (at least 20% improvement in total PANSS), safety, tolerability and pharmacokinetics.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Risperidone in people with Schizophrenia, 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 5 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 8 Jun 2011. 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 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?

Change in total PANSS (Positive and Negative Syndrome Scale for Schizophrenia) from baseline to the 8-week endpoint. 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 NCT00034749, 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 8 Jun 2011.
