| Schizoaffective Disorder | Drug: Placebo Drug: paliperidone palmitate | Phase 3 |
Schizoaffective disorder is a chronic illness and generally requires life-long treatment. To date however, no medication has been evaluated in the maintenance treatment of schizoaffective disorder. This is a randomized (study drug assigned by chance), double-blind (neither physician nor patient knows the name of the assigned drug), placebo-controlled, parallel-group, multicenter study to evaluate the efficacy and safety of paliperidone palmitate, as monotherapy or as an adjunct to mood stabilizers or antidepressants, relative to placebo in delaying the time to relapse in patients with schizoaffective disorder. This study explores the use of paliperidone palmitate either as monotherapy or as an adjunct to mood stabilizers or antidepressants (MS/AD) because both treatment approaches are commonly used in the clinical management of schizoaffective disorder. Patients with acute symptoms of schizoaffective disorder will be enrolled. The study will consist of 4 periods: an up to 7 days screening/tolerability period, a 13-week open-label flexible dose lead-in period, a 12-week open-label fixed dose stabilization period, and a 15 months double-blind relapse prevention period. Patients without previous exposure to paliperidone ER (Invega), paliperidone palmitate (Invega Sustenna), risperidone, or RISPERDAL CONSTA will be given 4 to 6 days of paliperidone ER 6mg/day for tolerability testing. Patients can continue their current antipsychotic regimen through Day -1 (the day before the start of the study period). During the open-label periods, all patients will be treated with paliperidone palmitate. An initial loading dose of 234 mg (150 mg eq.) of paliperidone palmitate will be given by deltoid injection followed by 156 mg (100 mg eq.) deltoid injection on Day 8. Starting on Day 36, injections may be administered in either the deltoid muscle or the gluteal muscle. Doses at Days 36, 64 and 92 may be increased or decreased within the range of 78 mg (50 mg eq.) and 234 mg (150 mg. eq.) as clinically indicated. Dose will be fixed (at Day 92 dose) during the 12-week stabilization period. Patients who meet pre-determined stabilization criteria will be eligible to enter the double-blind relapse prevention period and will be randomly assigned to either receive paliperidone palmitate (at the Day 92 dose) or placebo treatment. Patients will have intramuscular (i.m.) study drug injection and efficay and saftety evaluations performed every 4 weeks throughout the study. Efficacy will be evaluated during the study using a relapse assessment, the Positive and Negative Symptom Scale (PANSS), the Clinical Global Impression of Severity for Schizoaffective Disorder (CGI-S-SCA), the Personal and Social Performance Scale (PSP), the Young Mania Rating Scale (YMRS), and the Hamilton Rating Scale for Depression (HAM-D). Safety will be assessed throughout the study by monitoring of adverse events, clinical laboratory tests, electrocardiograms (ECGs), vital sign measurements (temperature, pulse, and blood pressure), weight, and the monitoring of extrapyramidal symptoms using the Extrapyramidal Symptom Rating Scale-Abbreviated (ESRS-A). Suicidality will be assessed by the Columbia Suicide Severity Rating Scale (C-SSRS). A 10 milliliter pharmacogenomic blood sample (sample for DNA research) will be collected from patients who give separate written informed consent for this part of the study. Participation in pharmacogenomic research is optional. Blood samples will be taken from patients being treated with lithium or valproate for the measurement of blood lithium or valproate levels. Approximately 52 mL (31 mL for patients who are not receiving lithium or valproate) of whole blood will be collected during the study. All patients will receive paliperidone palmitate 78, 117, 156, 234 mg (50, 75, 100, or 150 mg eq.) monthly by i.m. injection for the the first 25 weeks of the study (open-label periods). During the 15-month double-blind relapse prevention period, one half of the patients will be randomized to paliperidone palmitate treatment (50, 75, 100, or 150 mg eq. monthly i.m. injection) and the other half of the patients will be randomized to monthly placebo injection.

Primary Outcome Measures :
- Double-blind: Percentage of Participants Who Experienced Relapse [ Time Frame: Day 1 up to Month 15 of double blind relapse prevention period ]Relapse was defined as first occurrence of any 1 of following:psychiatric hospitalization due to worsening symptoms; any intervention employed to avert imminent hospitalization due to worsening symptoms or need for additional antipsychotic,antidepressants/mood stabilizing medication; deliberate self-injury,suicidal/homicidal ideation that is clinically significant as determined by investigator,or violent behavior resulting in clinically significant injury to another person or property damage; worsening of any 1 or more of 8 selected positive and negative syndrome scale(PANSS) items to a score of greater than or equal to (>= 6) after randomization(if the score for the corresponding item was less than or equal to [<=] 4 at randomization); worsening of certain other measures in specific ways at 2 consecutive visits. Relapse by subgroup of participants on monotherapy,adjunctive therapy to antidepressants/mood stabilizers,participants with psychotic symptoms/mood symptoms was examined.
Secondary Outcome Measures :
- Double-blind: Change From Baseline in Personal and Social Performance (PSP) Total Score at Week 64 (Total Mixed Model Repeated Measures [MMRM] Analysis of Covariance [ANCOVA]) [ Time Frame: Baseline and Week 64 of double blind relapse prevention period ]The PSP scale was designed to assess the degree of dysfunction a participant exhibits during a month prior to any visit within 4 domains of behavior: a) socially useful activities, b) personal and social relationships, c) self-care, and d) disturbing and aggressive behavior, each rated on 6-point scale (1=absent to 6=very severe). Total transformed score from 1 to 100 is generated from raw score based on clinical interpretation of scores generated in 4 areas of functioning. A score lying between 71 and 100 indicated a good functioning; one between 31 and 70 indicated varying degrees of difficulty, and a score of <=30 indicated functioning so poor that participant required intensive supervision.
- Open-label: Change From Baseline in Personal and Social Performance (PSP) Total Score at Endpoint [ Time Frame: Baseline and Endpoint (Week 13/LOCF) in Open-label (OL) Lead-in period, Endpoint (Week 25/LOCF) in open-label stabilization period ]The PSP scale was designed to assess the degree of dysfunction a participant exhibits during a month prior to any visit within 4 domains of behavior: a) socially useful activities, b) personal and social relationships, c) self-care, and d) disturbing and aggressive behavior, each rated on 6-point scale (1=absent to 6=very severe). Total transformed score from 1 to 100 is generated from raw score based on clinical interpretation of scores generated in 4 areas of functioning.

Total transformed score from 1 to 100 is generated from raw score based on clinical interpretation of scores generated in 4 areas of functioning. A score lying between 71 and 100 indicated a good functioning; one between 31 and 70 indicated varying degrees of difficulty, and a score of <=30 indicated functioning so poor that participant required intensive supervision.
- Double-blind: Number of Participants With Personal and Social Performance (PSP) Categorical Scores [ Time Frame: Baseline and Endpoint (Week 64/LOCF) in DB period ]The PSP scale was designed to assess the degree of dysfunction a participant exhibits during a month prior to any visit within 4 domains of behavior: a) socially useful activities, b) personal and social relationships, c) self-care, and d) disturbing and aggressive behavior, each rated on 6-point scale (1=absent to 6=very severe). Total transformed score from 1 to 100 is generated from raw score based on clinical interpretation of scores generated in 4 areas of functioning. Number of participants in each specific category; good functioning (PSP total score >70), variable functioning (PSP total score between 31 and 70), and poor functioning (PSP total score <=30) were assessed.
- Open-label: Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Endpoint [ Time Frame: Baseline and Endpoint (Week 13/LOCF) in OL Lead-in period, Endpoint (Week 25/LOCF) in open-label stabilization period ]The PANSS is a 30-item scale 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 and ranges from 30 to 210. Higher scores indicate worsening.

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 and ranges from 30 to 210. Higher scores indicate worsening.
- Open-label: Change From Baseline in Hamilton Rating Scale for Depression (HAM-D-21) Total Score at Endpoint [ Time Frame: Baseline and Endpoint (Week 13/LOCF) in OL Lead-in period, Endpoint (Week 25/LOCF) in open-label stabilization period ]The HAM-D-21 is a 21-item, clinician-rated scale to evaluate depressed mood as well as the vegetative and cognitive symptoms of depression. The items are rated on a 5-point (0 to 4) scale. The 5-point scale items use a rating of 0 (absent), 1 (doubtful to mild), 2 (mild to moderate), 3 (moderate to severe), and 4 (very severe). A rating of 4 is usually reserved for extreme symptoms. The responses for all 21 items are summed to yield the HAM-D-21 total score that ranges from 0-63.

- Open-label: Change From Baseline in Young Mania Rating Scale (YMRS) Total Score at Endpoint [ Time Frame: Baseline and Endpoint (Week 13/LOCF) in OL Lead-in period, Endpoint (Week 25/LOCF) in open-label stabilization period ]The YMRS was designed to measure the severity of manic symptoms, to gauge the effect of treatment on mania severity, and to detect a return of manic symptoms (for example relapse or recurrence). YMRS is a checklist of 11 items that are ranked on a scale of 0 to 4 or 0 to 8. Seven of the items (elevated mood, increased motor activity, sexual interest, sleep, language-thought disorder, appearance, and insight) are ranked 0 to 4 and have descriptors associated with each severity level (that is, 0, 1, 2, 3, 4). Four of the items (irritability, speech, content, and disruptive-aggressive behavior) are scored 0 to 8 and have descriptors for every other increment (that is, 0, 2, 4, 6, 8). The item score is based on participant's report of his or her condition and clinician's behavioral observations during the interview, with emphasis on the latter. Higher scores indicate worsening. Responses are summed to yield YMRS total score ranging from 0 to 60.
