About this study

Official title: The SOURCE Study: Schizophrenia Outcomes-utilization, Relapse, and Clinical Evaluation: a Prospective 2-year Observational Study of Patients With Schizophrenia Who Initiate Treatment With Injectable Risperidone Long-acting Microspheres (RISPERDAL CONSTA)

The purpose of this study is to examine treatment practices of adult schizophrenia patients by their own doctors, and to assess patient outcomes when treated with long-acting risperidone injection over a two-year period of observation.

Read the detailed description

This is a 2-year, prospective (a study in which the patients are identified and then followed forward in time for the outcome of the study), multi-center (at multiple sites), longitudinal (study that involves repeated observations of the same outcomes in the same people over long periods of time), observational study (study in which the investigators/ physicians observe the patients and measure their outcomes) in adults with schizophrenia (mental disorder characterized by a breakdown of thought processes and by poor emotional responsiveness). Physicians will determine the appropriate treatment for their patients, according to their usual practice. Patients starting treatment with long-acting risperidone injection (an antipsychotic medication) and meeting all the study criteria will be enrolled in the study. They will receive a dose of 25, 37.5 or 50 mg of risperidone every 2 weeks by intramuscular injection, and continue their treatment for schizophrenia according to usual care by their physicians. Patients will be asked questions at baseline and every three months for a period of two years to assess: efficacy of the medication, how well the patient is functioning, use of healthcare resources (eg, emergency room visits and hospitalizations) patient work status, quality of life and patient satisfaction with the medicine. Safety will be monitored throughout the study duration of 2 years.

What is being measured

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

  1. Change from baseline to 24 months in Clinical Global Impression of Severity (CGI-S) scores

    The CGI-S is a 7-point scale ranging from 1 to 7 (normal, not at all ill to among the most severely ill patients), which measures disease severity in psychiatric patients. The scale is completed by physician.

    Measured: Baseline (Month 0) to 24 months

  2. Clinical Global Impression of Change (CGI-C) scores during 24 months

    The CGI-C is a 7-point scale ranging from 1 to 7 (very much improved to very much worse), which is used to rate the change in the patient's illness compared to baseline. The scale assesses the patient's improvement over time. The scale is completed by physician.

    Measured: 24 months

  3. Change from baseline to 24 months in Global Assessment of Function (GAF) scores

    GAF is completed by the physician. GAF is a single item rating of the patient's psychological, social, and occupational functioning on a hypothetical continuum of mental health-illness. Respondents are asked to rate the subject's lowest level of functioning in the last week. GAF scores range from 0 to 100. (0 = Inadequate information, 1 = Persistent danger of severely hurting self or others and 100 = Superior functioning in a wide range of activities).

    Measured: Baseline to 24 months

  4. Change from baseline to 24 months in Personal and Social Performance (PSP) scores

    The PSP Scale is completed by the physician. PSP is a rating of a patient's level of functioning during the past month in 4 areas: (a) socially useful activities (including work and study); (b) personal and social relationships; (c) self-care; and (d) disturbing and aggressive behaviors. Scores range from 1 to 100. (1= Lack of autonomy in basic functioning and 100 = Excellent functioning in all 4 main areas).

    Measured: Baseline to 24 months

  5. Change from baseline to 24 months in Strauss-Carpenter Levels of Function (LOF) scores

    The Strauss-Carpenter LOF is completed by the physician. It consists of 9 items that can be grouped into 4 subscales: symptoms (absence of symptoms and recent hospitalizations), social contacts (frequency and quality of social contacts), work (quantity and quality of useful work), and function (ability to meet basic needs, fullness of life, and overall level of function). Each item is rated on a scale of 0 (worst functioning) to 4 (best functioning).

    Measured: Baseline to 24 months

Secondary outcomes (3)
  1. Change from baseline to 24 months in Quality of Life Assessment: Medical Outcomes Survey Short Form (SF-36) scores

    Patients completed the SF-36. The survey includes 36 items and evaluates health status in the past 4 weeks, in 8 different areas, which can be broadly summarized as physical health (physical functioning [PF], role-physical [RP], bodily pain [BP] and general health [GH]) and mental health (vitality [VT], social functioning [SF], role-emotional [RE], and mental health [MH]). In addition, the SF-36 evaluates health status in 2 broadly-defined areas, mental health and physical health. Higher scores represent better health status.

    Measured: Baseline to 24 months

  2. Change from baseline to 24 months in patient satisfaction with antipsychotic medication

    Patients are asked a single question to evaluate patient satisfaction with their current Anti psychotic medication. The question is, "The way I feel about my current antipsychotic is:" and used a 7-point response scale from 1 to 7 (extremely dissatisfied to extremely satisfy).

    Measured: Baseline to 24 months

  3. Change from baseline to 24 months in healthcare resource utilization

    Healthcare resource utilization including dates of hospitalizations (inpatient), emergency room (ER) visits, and outpatient visits, consultations with specialists and general practitioners. Relapse rates (from psychiatric hospitalizations, suicidal behavior or homicidal behavior) are also captured as resource utilization.

    Measured: Baseline to 24 months

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00246194, which also lists 3 linked publications.

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.
