About this study
Official title: A Randomized, Multicenter, Double-Blind, Non-inferiority Study of Paliperidone Palmitate 3 Month and 1 Month Formulations for the Treatment of Subjects With Schizophrenia
The purpose of this study is to demonstrate that a paliperidone palmitate 3 month formulation (PP3M) is as effective as the paliperidone palmitate 1 month formulation (PP1M) in the treatment of patients with schizophrenia who have been stabilized on PP1M.
Read the detailed description
This is a randomized (the study drug is assigned by chance), double blind (neither physician nor patient knows the treatment that the patient receives), parallel group (each group of patients will be treated at the same time), multicenter non-inferiority (the effect of the new treatment is not worse than that of the comparison treatment) study. A new formulation of paliperidone palmitate with a 3-month injection interval (PP3M) is being tested for use as maintenance treatment for subjects with schizophrenia who have been first stabilized on paliperidone palmitate with a 1-month injection interval (PP1M). The study consists of 3 phases: a screening/washout/tolerability phase (up to 21 days); a 17-week open-label (all people know the identity of the intervention) stabilization phase (referred to as the Open-label Phase) and a 48-week fixed dose, randomized, double-blind controlled phase (referred to as the Double-blind Phase). After completion of the Screening Phase, all patients will receive PP1M in the Open-label Phase. During this time, flexible dosing will occur at Weeks 5 and 9. At Week 13 patients are to receive the dose of PP1M that was administered at Week 9. Patients who are clinically stable at the end of the Open-label Phase will enter the Double-blind Phase and will be randomly assigned in a 1:1 ratio to receive fixed doses of PP3M or PP1M.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants Without Relapse at Week 48 During the Double-Blind Phase
Relapse defined as: Psychiatric hospitalization;participant had an increase of 25 percent in total PANSS score from randomization for 2 consecutive assessments separated by 3-7 days if score at randomization was greater than (>) 40; had a 10 point increase in total PANSS score from randomization for 2 consecutive assessments separated by 3-7 days if score at randomization was less than or equal to (<=) 40; deliberate self-injury or exhibited violent behavior resulting in suicide, clinically significant injury;suicidal or homicidal ideation and aggressive behavior;For PANSS items-had a score of greater than or equal to (>=) 5 after randomization for 2 consecutive assessments separated by 3-7 days on any of above items if maximum score for these above PANSS items was <=3 at randomization; had a score of >=6 after randomization for 2 consecutive assessments separated by 3-7 days on any of above items if maximum score for these above PANSS items was 4 at randomization.
Measured: Up to 48 weeks
Secondary outcomes (6)
Change From Double-Blind (DB) Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 48
The neuropsychiatric symptoms of schizophrenia were assessed by means of the 30-item Positive and Negative Syndrome Scale (PANSS). The PANSS provides a total score (sum of the scores of all 30 items) ranging from 30 to 210, higher scores indicate more severe neuropsychiatric symptoms of schizophrenia. Scores for 3 subscales, that is, for positive subscale (sum of the scores of all 7 items) and negative subscale (sum of the scores of all 7 items) ranges from 7 (absent) to 49 (extreme psychopathology), and for the general psychopathology subscale (sum of the scores of all 16 items) score ranges from 16 (absent) to 112 (extreme psychopathology).
Measured: DB Baseline (Week 17) and 48 week or DB Endpoint
Change From DB Baseline in Clinical Global Impression Severity (CGI-S) Scale Score at Week 48
The Clinical Global Impression Severity (CGI-S) rating scale is a 7 point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill participants". Higher scores indicate worsening.
Measured: DB Baseline (Week 17) and 48 week or DB Endpoint
Change From DB Baseline in Personal and Social Performance (PSP) Total Score at Week 48
The Personal and Social Performance (PSP) scale assesses degree of a participant's dysfunction within 4 domains of behavior: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behavior. Score ranges from 1 to 100. Participants with a score of 71 to 100 have mild degree of difficulty; from 31 to 70, varying degrees of disability; less than or equal to 30, functioning so poorly as to require intensive supervision.
Measured: DB Baseline (Week 17) and 48 week or DB Endpoint
Percentage of Participants Who Met the Criteria for Symptomatic Remission Based on Andreasen Criteria
Symptomatic remission criterion was defined as having a simultaneous score of mild or less on all selected PANSS items (P1, P2, P3, N1, N4, N6, G5, and G9). Symptomatic remission was defined for the last 6 months of the Double-blind Phase as meeting the remission criterion during the 6 months prior to the End of study visit during the Double-blind Phase, with one excursion allowed.
Measured: Weeks 41 to 65
Change From Baseline in Positive and Negative Syndrome Subscales Score at Week 48
The neuropsychiatric symptoms of schizophrenia were assessed by means of the 30-item Positive and Negative Syndrome Scale (PANSS). The PANSS provides a total score (sum of the scores of all 30 items) ranging from 30 to 210, higher scores indicate more severe neuropsychiatric symptoms of schizophrenia. Scores for 3 subscales, that is, for positive subscale (sum of the scores of all 7 items) and negative subscale (sum of the scores of all 7 items) ranges from 7 (absent) to 49 (extreme psychopathology), and for the general psychopathology subscale (sum of the scores of all 16 items) score ranges from 16 (absent) to 112 (extreme psychopathology).
Measured: DB Baseline (Week 17) and 48 week or DB Endpoint
Change From Baseline in Marder Factor Subscale Score at Week 48
5 PANSS Marder factor scores (positive symptoms [range:8 to 56], negative symptoms [range: 7 to 49], disorganized thoughts [range: 7 to 49], uncontrolled hostility/excitement [range: 4 to 28], and anxiety/depression [range: 4 to 28]) were examined to gain insight into the symptoms affected by treatment with the study drug. Negative change from baseline in subscales score for positive symptoms, negative symptoms, disorganized thoughts, uncontrolled hostility/excitement, and anxiety/depression indicates improvement in various symptoms of schizophrenia.
Measured: DB Baseline (Week 17) and 48 week or DB Endpoint

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 2 May 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants Without Relapse at Week 48 During the Double-Blind Phase (time frame: Up to 48 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01515423, which also lists 7 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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 May 2016.
