Trial Outcomes & Findings for Evaluation of Effectiveness and Safety of Flexible-dose Paliperidone Extended Release in Patients With Schizoaffective Disorder. (NCT NCT00412373)

NCT ID: NCT00412373

Last Updated: 2014-05-09

Results Overview

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 that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of the sum of all 30 PANSS items. Higher scores indicate worsening.

Participant Flow

391 subjects were enrolled in the study. There were 80 screen fails (did not meet inclusion/exclusion criteria). 311 subjects were randomized. 309 subjects were included in the Safety Analysis Set (randomized and took at least one dose of study drug). 304 subjects were included in the Intent-to-Treat analysis set (had baseline/postbase PANSS).

Placebo
A placebo control was used to establish the frequency and magnitude of changes in clinical endpoints that could occur in the absence of active treatment.
Paliperidone Extended-Release (ER)
Paliperidone (9-hydroxy-risperidone, R076477) is an atypical antipsychotic agent approved for the treatment of schizophrenia and is in development for the treatment of bipolar disorder and schizoaffective disorder. Paliperidone is a monoaminergic antagonist that exhibits the characteristic dopamine type 2 (D2) and serotonin (5-hydroxytryptamine \[5-HT\]) type 2A (5HT2A) antagonism of the newer, or second-generation, antipsychotic drugs. Paliperidone is available in an oral formulation using extended-release (ER).

PRIMARY outcome

Timeframe: Baseline

Population: The Intent-to-Treat population included all randomly assigned subjects who received at least 1 dose of study medication (or any portion of a dose) and had both baseline and at least 1 postbaseline PANSS assessment.

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 that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of the sum of all 30 PANSS items. Higher scores indicate worsening.

Clinician-rated scale that evaluates depressed mood as well as the vegetative and cognitive symptoms of depression. The items are rated on either a 5-point (0 to 4) or a 3-point (0 to 2) scale. The 5-point scale uses a rating of 0 (absent), 1 (doubtful to mild), 2 (mild to moderate), 3 (moderate to severe), and 4 (very severe). Higher scores indicate worsening. The responses are summed to yield the HAM-D-21 score that ranges from 0-63.

Paliperidone (9-hydroxy-risperidone, R076477) is an atypical antipsychotic agent approved for the treatment of schizophrenia and is in development for the treatment of bipolar disorder and schizoaffective disorder. Paliperidone is a monoaminergic antagonist that exhibits the characteristic dopamine type 2 (D2) and serotonin (5-hydroxytryptamine \[5-HT\]) type 2A (5HT2A) antagonism of the newer, or second-generation, antipsychotic drugs. Paliperidone is available in an oral formulation using extended-release (ER).

Higher scores indicate worsening. The responses are summed to yield the YMRS total score, which ranges from 0 to 60.
