Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is an open-label (all people know identity of intervention), randomized (the study drug is assigned by chance), multicenter (conducted in more than 1 center), and exploratory study in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality) or schizoaffective disorder (mixed psychiatric disorder relating to complex psychotic state that has features of both schizophrenia and mood disorder). Duration of this study will be 24 months. Study assessment visits will be conducted at Screening, Baseline, Week 2, every 4 weeks till Week 22, at Week 28, every 12 weeks till Week 88 and at Week 104. All eligible participants will receive either risperidone long acting injection 25 milligram (mg) intramuscularly (into the muscle) along with their current oral medication (atypical antipsychotic - risperidone, quetiapine, olanzapine) or only their current oral medication. Efficacy will be evaluated primarily by Positive and Negative Syndromes Scale (PANSS), time to relapse and Social and Occupational Functioning Assessment Scale (SOFAS). Participants's safety will be evaluated throughout the study mainly by Abnormal Involuntary Movement Scale (AIMS), Barnes Akathisia Rating Scale (BARS), and Simpson Angus Scale (SAS).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 104 or Last Reported Visit (LRV)
Time Frame: Baseline, Week 104 or LRV
The PANSS provides a total score (sum of the scores of all 30 items) and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme). The PANSS total score consists of the sum of all 30 PANSS items and ranges from 30 to 210. Higher scores indicate worsening.
Baseline, Week 104 or LRV
Time to Relapse
Time Frame: Week 10 (post-stability) up to Week 104 or LRV
Time to relapse was calculated from the start of the maintenance phase to date of relapse according to Csernansky: "Psychiatric hospitalization; increased level of psychiatric care from start of maintenance period and 25 percent increase in total PANSS score from first maintenance visit, or 10 points increase where PANSS at start of maintenance period was 40 or less; deliberate self-injury, suicidal or homicidal ideation; violent to others; property damage; or substantial clinical deterioration, defined as Clinical Global Impression of Change (CGI-C) score of 6 (much worse)".
Week 10 (post-stability) up to Week 104 or LRV
Change From Baseline in Social and Occupational Functioning Assessment Scale (SOFAS) at Week 104 or LRV
Time Frame: Baseline, Week 104 or LRV
The SOFAS focused exclusively on participants' level of social and occupational functioning. The SOFAS is a 100 point single item scale that rates functioning of a participant. The scale values range from 1=most impaired to 100=healthiest individual. The scale also includes a rating point of 0=missing information.
Baseline, Week 104 or LRV

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Calgary Depression Symptom Scale (CDSS) Score at Week 104 or LRV
Time Frame: Baseline, Week 104 or LRV
Co-morbid depressive symptoms are evaluated by change in CDSS Score which was developed to assess symptoms of depression in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self). It consists of 9 items, each scored from 0 (absent) to 3 (severe). The total score is a sum of the scores of each item and may range from 0 to 27. Higher score more severe pathology. Data presented here represents the change from baseline to endpoint.
Baseline, Week 104 or LRV
Change From Baseline in Young Mania Rating Scale (YMRS) at Week 104 or LRV
Time Frame: Baseline, Week 104 or LRV
Co-morbid symptoms of mania are evaluated by change in YMRS Score which is an 11-item scale to assess symptoms of mania, Four items are rated on a scale from 0 (symptom not present) to 8 (symptom extremely severe). The remaining items are rated on a scale from 0 (symptom not present) to 4 (symptom extremely severe). The YMRS total score ranges from 0 (the least) to 60 (the worst).
Baseline, Week 104 or LRV
Change From Baseline Hamilton Anxiety Scale (HAM-A) Total Score at Week 104 or LRV
Time Frame: Baseline, Week 104 or LRV
The HAM-A is a 14-item scale designed to measure anxiety in individuals. Each question reflects a symptom of anxiety and physical as well as mental symptoms are represented. The answers range from 0 which signifies a complete lack of that symptom to 4, which indicates a very severe show of anxiety with that symptom. Total score ranges from 0 to 56. Lower score indicates less affected.
Baseline, Week 104 or LRV
Percentage of Participants With Relapse
Time Frame: Week 10 (post-stability) up to Week 104 or LRV
Relapse was defined according to Csernansky: "Psychiatric hospitalization; increased level of psychiatric care from start of maintenance period and 25 percent increase in total PANSS score from first maintenance visit, or 10 points increase where PANSS at start of maintenance period was 40 or less; deliberate self-injury, suicidal or homicidal ideation; violent to others; property damage; or substantial clinical deterioration, defined as CGI-C score of 6 (much worse)".
Week 10 (post-stability) up to Week 104 or LRV
Number of Participants With Cognitive Assessment Using Trail A
Time Frame: Week -2, 104 or LRV
Cognitive assessments were done using Trail test A which measured variety of functions, including motor speed, visual scanning, attention and visual motor integration. Participants must connect numbered circles in a variety of orders.
Week -2, 104 or LRV
Number of Participants With Cognitive Assessments Using Trail B
Time Frame: Week -2, 104 or LRV
Cognitive assessments were done using Trail test B, which measured variety of functions, including motor speed, visual scanning, attention and visual motor integration. In Trail B, 2 sets of circles contain numbers and letters, and the participant must connect them in alternating order. Trail B is also a measure of executive functions as it requires planning and decision-making.
Week -2, 104 or LRV
Total Words Score Over Time
Time Frame: Baseline, Week 104 or LRV
Controlled Word Association Test (COWAT) was used to assess verbal fluency. Participants are given 3 different letters of the alphabet and asked to say as many words beginning with each letter within a controlled time. Participants are then asked to identify as many words as possible in 3 different categories (animals, fruits and vegetables) within a specified period of time. The total score is a sum of all three categories scores. The total score ranges from 0-90, the higher the score the higher the verbal fluency.
Baseline, Week 104 or LRV
Change From Baseline in Drug Attitude Inventory (DAI-10) Score at Week 104 or LRV
Time Frame: Up to Week 104 or LRV
The DAI, a 10-item scale to assess how the attitude of schizophrenia participants toward their medications may affect compliance. Respondents indicate 'true' or 'false' for each item. An overall calculated score ranged from -10 to 10, where a positive score indicated a positive subjective response (compliant), a negative score indicated non-compliance. Change: score at observation minus score at baseline.
Up to Week 104 or LRV
Change From Baseline in Standardized Mental Component Scale Score in Short Form 36 (SF-36) at Week 104 or LRV
Time Frame: Up to Week 104 or LRV
The SF-36 is a survey of participant health. It calculates two standardized scales: the standardized mental component scale and the standardized physical component scale. The standardized scales are calculated as weighted sums of the 8 scores, which are: vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, and mental health. Each item is scored on a 0-100 range; and standardized mental component scale score is calculated as weighted average of individual item scores on a 0-100 range, where 100 signify highest level of functioning. The change from baseline in mental component scale score was reported.
Up to Week 104 or LRV

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Barnes Akathisia Rating Scale (BARS) Global Clinical Assessment
Time Frame: Baseline, Week 104 or LRV
The BARS evaluates akathisia (feeling of restlessness) associated with the use of antipsychotic medications, including an objective and a subjective component plus a global impression. Components are rated on a scale of 0 (normal or absence of restlessness)-3 (intense restlessness) and 0 (absent)-5 (severe akathisia) for the global clinical assessment. Number of participants in each global clinical assessment scale are reported.
Baseline, Week 104 or LRV
Simpson Angus Scale (SAS)
Time Frame: Baseline, Week 104 or LRV
The SAS is a 10-item scale used to measure the symptoms of parkinsonism (slow movements) or parkinsonian side-effects related to the use of antipsychotic medications. The 10 items are rated on a 5-point scale (0=complete absence, 4=extreme presence) after a brief neurological examination and observation of the participants' gait (slow, shuffling walk). Total score is sum of individual item scores (range 0 to 40); higher score indicates more affected.
Baseline, Week 104 or LRV
Abnormal Involuntary Movement Scale (AIMS)
Time Frame: Baseline, Week 104 or LRV
The AIMS is a 12-item scale to provide a numeric measure to the observed abnormal movements in different parts of the body. Information is collected after a brief neurological examination and is scored on a 5-point scale (0=none, 4=severe). Ten items are scored in a 5-point scale (0 = none/normal, 4 = severe) which evaluates abnormal movements in three main anatomic areas (orofacial area, extremities, and trunk). Two items are yes/no questions regarding dental status. Total scores range from 0 to 42 with higher values indicating more severity.
