ClinicalTrials.gov Identifier:	NCT00791349

Purpose

The purpose of this study is to assess the cardiovascular safety of paliperidone in patients with schizophrenia or schizoaffective disorder, with particular attention to the length of the QT/QTc interval, to measure and review other electrocardiogram (ECG) parameters, such as QRS and PR intervals, to explore the relationship between the pharmacokinetics of paliperidone and ECG parameters of interest, and to explore the safety and tolerability of paliperidone

Primary Outcome Measures:

To assess the cardiovascular safety of paliperidone in schizophrenic or schizoaffective patients, with particular attention to the length of the QT/QTc interval. Other ECG parameters, such as QRS and PR intervals, will also be carefully measured

Secondary Outcome Measures:

To explore the relationship between the pharmacokinetics of paliperidone and ECG parameters of interest, and to explore the safety and tolerability of paliperidone

Estimated Enrollment:	100
Study Start Date:	February 2005
Study Completion Date:	May 2005

Detailed Description:

This is a multicenter, placebo- and positive-controlled, randomized study consisting of 3 periods: a screening period of up to 14 days (including a 5-day washout period), a double-blind period of 10 days (including the treatment phase [Days 1 to 8] and the posttreatment phase [Days 9 and 10]), and an end-of-study evaluation.

Eligible patients will be randomly assigned to treatment with either paliperidone or moxifloxacin. Patients randomly assigned to receive paliperidone will receive placebo on Day 1, paliperidone 4 mg on Day 2, paliperidone 6 mg on Day 3, and paliperidone 8 mg on Days 4 through 8. Patients assigned to receive moxifloxacin will receive placebo on Days 1 through 7 and moxifloxacin 400 mg on Day 8. The moxifloxacin treatment group will provide a concurrent active control to confirm that the study is adequate to detect a drug effect (i.e., assay sensitivity) on QTc interval. Baseline ECGs will be recorded on the last day of the washout period (Day 1). Serial time matched 12 lead ECG triplicate readings will be recorded on Days 1, 2, 3, 4, 5 (predose), 8, 9, and 10. This study is being conducted to thoroughly assess potential QT/QTc interval changes following administration of paliperidone. The results from this safety study, along with the ECG results from all paliperidone clinical studies, will be used in the evaluation of the cardiovascular safety of paliperidone.

Paliperidone IR orally once daily: 4 mg on Day 2, 6 mg on Day 3, and 8 mg on Days 4 through 8; Active control: a single oral dose of moxifloxacin 400 mg on Day 8

Eligibility

Ages Eligible for Study:	18 Years to 50 Years

Criteria

Inclusion Criteria:

Patients must have a diagnosis of schizophrenia or schizoaffective disorder as defined by DSM-IV criteria, with no exacerbation of psychosis for at least 3 months prior to screening
Patients must have a normal 12-lead ECG at screening and on Day -1, including: Normal sinus rhythm (heart rate between 50 and 100 beats per minute)
QTcB interval < = 430 msec for men, < = 450 msec for women
QRS interval <110 msec, PR interval < 200 msec
Patients must weigh > = 50 kg ( > = 110 lb), with a body mass index > = 18 and < = 35 kg/m2
Female patients must be postmenopausal (for at least 1 year), surgically sterile, or practicing an effective non-hormonal method of birth control (e.g., intrauterine device, double-barrier method, male partner sterilization, abstinence) before entry and throughout the study
Must have a negative serum beta human chorionic gonadotropin pregnancy test at screening
And must have a negative urine pregnancy test within 24 hours before Day 1 of the randomization period

Exclusion Criteria:

Patient meets DSM-IV criteria for psychoactive substance dependence in the 3 months prior to screening
Patient is at risk for suicidal or violent behavior, as judged by the investigator: Patient has a clinically significant abnormality on ECG at screening or on Day -1 of the study
Patient has a heart rhythm disturbance that is known or suggested by history or that is demonstrated on ECG at screening
Patient has a blood pressure outside of the normal range (supine systolic blood pressure <90 or >140 mmHg and/or diastolic blood pressure <60 or > 90 mmHg)
Patient has unusual T-wave morphology in a majority of leads of the ECG (such as bifid T waves, low T waves) or prominent U waves at screening: Patient has a history of additional risk factors for torsade de pointes, such as heart failure, hypokalemia, family history of known long QT interval syndrome, or sudden unexplained death at a young age ( < = 40 years) in a first-degree relative (i.e., biological parent, sibling, or offspring)
Patient has a relevant history of any significant and/or unstable cardiovascular, respiratory (including bronchial asthma), neurologic (including seizures or significant cerebrovascular disease), renal, hepatic, endocrine, immunologic, ophthalmologic, hematological, or other systemic disease
