Study Description

Brief Summary:

The purpose of this study is to evaluate the tolerability and safety of paliperidone ER (extended-release) in doses between 3 milligrams per day and 12 milligrams per day in the treatment of patients with schizophrenia or schizoaffective disorder and liver disease.

Condition or disease	Intervention/treatment	Phase
Schizophrenia; Schizoaffective Disorder; Psychotic Disorders	Drug: Treatment as usual (TAU), Paliperidone ER	Phase 4

Detailed Description:

Patients with schizophrenia or schizoaffective disorder commonly have other conditions that may affect the liver, such as alcohol abuse and/or chronic liver infections (hepatitis). Although single-dose studies in patients with liver disease are conducted to test the safety of medications, there is less information about the safety of treatment with medications for schizophrenia in this at-risk population of patients with schizophrenia or schizoaffective disorder and liver disease. This 9-week study is open-label (both patient and investigators know what study drug and dose of study drug the patient is taking) and has 2 phases. During Phase 1, which lasts 4 weeks, patients will continue to take whatever medication they are already taking for schizophrenia (TAU, or treatment as usual). During the first week of Phase 2, patients will receive decreasing doses of TAU and increasing doses of paliperidone ER. For the rest of Phase 2, which lasts 4 more weeks, patients will take paliperidone ER in doses between 3 mg/day and 12 mg/day, as prescribed by the study doctor. This study will evaluate adverse events and will use several scales and tests to measure the effectiveness of paliperidone ER in patients with an established diagnosis of schizophrenia or schizoaffective disorder and liver disease. Study assessments include the PANSS (Positive and Negative Symptom Scale for Schizophrenia), CGI (Clinical Global Impression scale), MSQ (Medication Satisfaction Questionnaire), sleep VAS (Visual Analog Scale), SF-36 (Short Form 36 Health Survey), and PSP (Personal and Social Performance Scale). Each assessment will be performed at least two times during the course of the study, but some assessments will be done more frequently. Visits are scheduled every 1 to two weeks during the 9 week study.

The hypothesis is that paliperidone ER can be used safely in patients with schizophrenia or schizoaffective disorder who also have identified liver disease. During Phase 1 of the study, patients will continue to take whatever medication they are already taking for schizophrenia (TAU, or treatment as usual) for 4 weeks. For the first week of Phase 2, patients will receive decreasing doses of TAU. During Phase 2, patients will take paliperidone ER in doses between 3 milligrams per day and 12 milligrams per day by mouth for 5 weeks.

Outcome Measures

Primary Outcome Measures :

1. The Difference in the Incidence of Any Adverse Events When Patients Switch Their Antipsychotic From Treatment as Usual (TAU) to Paliperidone ER [ Time Frame: Day 1 - Day 62 ]
   Adverse Event summary for both serious adverse events and other adverse events. Please see the Clinical Study Report Synopsis for results on this primary outcome measure or the AE section for a detailed breakdown of each adverse event preferred term in both categories.

Secondary Outcome Measures :

1. Positive and Negative Symptoms of Schizophrenia (PANSS) Change From Baseline [ Time Frame: Day 1 - Day 62 ]
   The PANSS is a 30-item scale (range 30-210) 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 (1="Absent", 2="Minimal", 3="Mild", 4="Moderate", 5="Moderate/Severe", 6="Severe", 7="Extreme").The PANSS total score consists of the sum of all 30 PANSS items. Higher scores indicate more severe neuropsychiatric symptoms of schizophrenia.
2. Clinical Global Impression of Severity (CGI-S) Change From Baseline [ Time Frame: Day 1 - Day 62 ]
   The CGI-S (range 1-7) is a standardized, clinician-rated assessment to rate the severity of illness of the patient. The clinician assessed the severity of illness using the following categories: 1 = normal, 2 = borderline ill, 3 = mildly ill, 4 = moderately ill, 5 = markedly ill, 6 = severely ill, 7 = among the most extremely ill. The minimum score is 1 and maximum score is 7, with higher scores indicating more severe illness.
3. Personal and Social Performance Score (PSP) Change From Baseline [ Time Frame: Day 1 - Day 62 ]
   The PSP (range 1-100) is a validated clinician-rated assessment of functioning. Four areas of functioning (socially useful activities, personal/social relationships, self-care, disturbing/aggressive behaviors) are assessed on a 6-point scale (0=absent to 5=very severe). A transformed score from 1 to 100 is generated from the raw score based on the clinical interpretation of the scores generated in the 4 areas of functioning, with a higher transformed score indicating better function.
