About this study
Official title: Evaluation of Efficacy and Safety of Risperidone in Long-acting Microspheres in Patients With Schizophrenia, Schizophreniform or Schizoaffective Disorders Diagnosed According to the DSM-IV Criteria, After Switching Treatment With Any Antipsychotic Therapy With Long-acting Microspheres of Risperidone
The purpose of this study is to evaluate the efficacy and safety of long acting injectable microspheres of risperidone in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self), schizophreniform or schizoaffective disorders (disorders in which there is a loss of ego boundaries or a gross impairment in reality testing with delusions or prominent hallucinations).
Read the detailed description
This is an open-label (all people know the identity of the intervention), longitudinal (participants are followed over time with continuous or repeated monitoring of risk factors or health-outcomes), non-randomized (a clinical trial in which the participants are not assigned by chance to different treatment groups), single-center study to evaluate the efficacy and safety of long acting microspheres of risperidone in adult participants with schizophrenia, schizophreniform or schizoaffective disorders. The duration of this study will be 12 months and duration of treatment will be 6 months. The study will include 4 visits: Baseline, and 3 follow-up visits including Week 4, 12 and 26. All eligible participants will be treated with risperidone 25 milligram (mg) intramuscular injection (injection of a substance into a muscle) for every two weeks up to 6 months. Participants with persistent symptoms and/or requiring higher doses of antipsychotics (agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect) will be initiated with higher doses of risperidone. Doses will be adjusted according to the response of the treatment. Efficacy and safety of the participants will be primarily evaluated by Positive and Negative Syndromes Scale (PANSS) and Extrapyramidal Symptom Rating Scale (ESRS), respectively. Participants' quality of life and safety will be monitored throughout the study.

What participants receive. In a randomised study each person is assigned to one group by chance.
RisperidoneDrug
Risperidone 25 milligram (mg) will be given as intramuscular injection for every 2 weeks up to 6 months. Participants with persistent symptoms and/or requiring higher doses of antipsychotics will be administered higher doses of risperidone. Doses will be adjusted as per Investigator's discretion.

Receives: Drug: Risperidone |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 26
The PANSS is a 30-item scale designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and poor impulse control. The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of the sum of all 30 PANSS items and ranges from 30 to 210, higher scores indicate worsening. Change at Week 26 score is calculated as Baseline score minus Week 26 score.
Measured: Baseline and Week 26
Secondary outcomes (5)
Clinical Global Impressions (CGI) - Disease Severity Score
The CGI rating scale is a 7-point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill participants", higher scores indicate worsening.
Measured: Baseline and Week 26
Short Form-36 (SF-36) - Quality of Life Score
The SF-36 is a standardized survey evaluating 8 aspects of functional health and well being: vitality, physical function, social function, physical role, emotional role, bodily pain, general health, mental health. Each item is scored on a scale ranging from 0-100 (100=highest level of functioning).
Measured: Baseline and Week 26
Global Assessment of Functioning (GAF) Score
The GAF is a 100-point tool to measure overall psychological, social and occupational functioning of adults. The higher score range (91 to 100) refers to a superior functioning in a wide range of activities, and absence of symptoms. The lower score range (1 to 10) refers to persistent danger of severely hurting self or others; or persistent inability to maintain minimum personal hygiene; or serious suicidal act with clear expectation of death.
Measured: Baseline and Week 26
Patient Satisfaction With Treatment
Participants' were assessed for their satisfaction with the current antipsychotic treatment on a 5-point scale/questionnaire: very good, good, reasonable, moderate or poor.
Measured: Baseline and Week 26
Extrapyramidal Symptom Rating Scale (ESRS) Score
An ESRS scale is used to assess the extrapyramidal symptoms attributable to antipsychotics. It consists of 8 items to assess individual symptoms and each item is assessed from 0 (none, absent) to 4 (severe). The total score is the sum of the 8 item scores, for a total range of 0 (normal) to 32 severe). The items for the assessment of individual symptoms are classified into 4 categories of parkinsonism, akathisia, dystonia and dyskinesia.
Measured: Baseline and Week 26

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Risperidone in people with Schizophrenia and Schizophreniform Disorder, run by Janssen-Cilag Ltd..
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 5 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 14 Aug 2013. 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 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 25 Jul 2013). 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?
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 26 (time frame: Baseline and Week 26). 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 14 Aug 2013; AzTrials last refreshed its copy on 5 Nov 2026.
