April 25, 2025 updated by: Janssen-Cilag Ltd.

A 52-Week, Open-Label, Prospective, Multicenter, International Study of a Transition to the Paliperidone Palmitate 3-Month Formulation In Patients With Schizophrenia Previously Stabilized on the Paliperidone Palmitate 1-Month Formulation

The purpose of this study is to estimate the proportion of participants fulfilling criteria for symptomatic remission following a transition to 12 months treatment with flexible-dose paliperidone palmitate 3 month formulation (PP3M) in participants with schizophrenia previously adequately treated with paliperidone palmitate 1 month formulation (PP1M) for at least 4 months.

Detailed Description

This is an international, multicenter (study conducted at multiple sites) study designed to estimate remission rates and assess treatment response, tolerability, and patterns of use of Paliperidone Palmitate 3-Month Formulation (PP3M) in a diverse population of participants with schizophrenia. The study will consist of a screening phase (Day -7 to Day 1), a 52-week, open-label, flexible-dose PP3M treatment phase and a follow up safety assessment 3 months ( +/-14 days ) after the month 12 visit or early discontinuation. Participants' Safety will be monitored throughout the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving Symptomatic Remission Based on Positive and Negative Syndrome Scale (PANSS)
Time Frame: Month 12
The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self). The PANSS provides a total score and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each item scored on a scale of 1 (absent), 2 (minimal), 3 (mild), 4 (moderate), 5 (moderately severe), 6 (severe) and 7 (extreme). The total score ranges from 30 to 210 and higher score indicates greater severity. Symptomatic remission is defined as achieving intensity level of mild or moderate on PANSS scale by all 8 items as the determinants for symptomatic remission: delusions, unusual thought content, hallucinatory behavior, conceptual disorganization, mannerisms/posturing, blunted affect, social withdrawal, lack of spontaneity.
Month 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving Symptomatic Remission Based on Positive and Negative Syndrome Scale (PANSS) at Month 6, 9 and 12
Time Frame: Month 6, Month 9 , and Month 12
PANSS is a 30-item scale to assess neuropsychiatric symptoms of schizophrenia. PANSS provides a total score and scores for 3 subscales, positive subscale (7 items), negative subscale (7 items), and general psychopathology subscale (16 items), each item scored on a scale of 1 (absent), 2 (minimal), 3 (mild), 4 (moderate), 5 (moderately severe), 6 (severe) and 7 (extreme). Total score ranges from 30 to 210 and higher score indicates greater severity. Symptomatic remission is defined as achieving intensity level of mild or moderate on PANSS scale by all 8 items as the determinants for symptomatic remission: delusions, unusual thought content, hallucinatory behavior, conceptual disorganization, mannerisms/posturing, blunted affect, social withdrawal, lack of spontaneity with the achieved intensity level maintained for at least 6 months.
Month 6, Month 9 , and Month 12
Time to Symptomatic Remission
Time Frame: Up to Month 12
Time to Symptomatic Remission will be reported. Symptomatic remission is defined as achieving intensity level of mild or moderate on PANSS scale by all 8 items as the determinants for symptomatic remission: delusions, unusual thought content, hallucinatory behavior, conceptual disorganization, mannerisms/posturing, blunted affect, social withdrawal, lack of spontaneity with the achieved intensity level maintained for at least 6 months.
Up to Month 12
Percentage of Participants who Meet the Remission Severity Criteria
Time Frame: Up to Month 12
Remission severity criteria that is, a score of mild or less [less than or equal to 3] on all selected PANSS items [P1, P2, P3, N1, N4, N6, G5, and G9]) at each time point.
Up to Month 12
Non-Inferiority of Change in PANSS Total Score From Baseline to Month 12 last-observation-carried-forward (LOCF)
Time Frame: Up to Month 12
Maintained efficacy will be investigated using the Schuirmann's test to test the change at last-observation-carried-forward (LOCF) endpoint in total PANSS score at endpoint versus baseline with a non-inferiority margin of 5 points on the PANSS scale.
Up to Month 12
The proportion of subjects with PANSS response
Time Frame: Up to Month 12
The PANSS is a 30-item scale to assess the neuropsychiatric symptoms of schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self). The PANSS provides a total score and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items), each item scored on a scale of 1 (absent), 2 (minimal), 3 (mild), 4 (moderate), 5 (moderately severe), 6 (severe) and 7 (extreme). The total score ranges from 30 to 210 and higher score indicates greater severity.
