Clinical Trial Summary

In a population of patients suffering from schizophrenia being treated for an episode of clinical destabilization and followed for a period of twelve months, the main objective is to evaluate the proportion of patients achieving functional remission and its relationship to clinical remission.

Description:

Prospective, national, noninterventional study. One year follow up with three evaluation dates (D0, D180 and D360). The participation of a subject in this study will in no way impact the regular care of the subject or any benefits they are otherwise entitled to. All treatment decisions will be made at the discretion of the participating physician, in accordance with his clinical practice and with approved local prescribing information. Only data available from clinical practice will be collected. Evaluation methods: patient history and clinical examination, clinical global impression (CGI): Improvement in CGI, social performance evaluation [functional remission of general schizophrenia (FROGS scale)], clinical remission evaluation: 8 items of the Positive and negative syndrome (PANSS) Scale, psychosocial remission evaluation (PSP scale), current insight evaluation: insight scale for psychosis, subjective well being under neuroleptic treatment (SWN scale), health condition [Euro quality of life - 5 Dimensions (EQ-5D)]; Judgment Criteria: functional remission is defined as an overall score of greater than or equal to (>=) 57 on the FROGS scale, functional response is defined as improvement of >= 7 points on the FROGS scale. Safety evaluation: no tolerance analysis will be performed, adverse event (AE) and serious adverse event (SAE) with J&J products will be collected and transmitted according to J&J timelines/process.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Clinical Remission	Defined by the absence of a score greater than (>) 3 on the Positive and Negative Syndrome Scale (PANSS) 8 item scale at two consecutive evaluations (D0 and D180 or D180 and D360). The PANSS 8 items allows to evaluate the clinical remission, defined by a score less than or equal to (=<) 3 on each eight items during a six month minimum period. Each of the 8 PANSS items must be scored from 1 (not at all) to 7 (extremely). More the score is high, more the severity rate of the symptom is high.	1 year Follow up
Primary	Functional Remission	Defined by Functional Remission of General Schizophrenia (FROGS) scale global score and its relationship with clinical remission. FROGS scale: The "Functional Remission of General Schizophrenia" (FROGS) is a 19 items scale gathered in five fields ("Daily life", "Activities", "Adaptation Quality", "relational Life", "Health and treatment") used to evaluate the functional remission in schizophrenia. The 19 items must be scored from 1(not done) to 5 (perfectly done). The total score is 19 to 95. More the score is high, better the functioning abilities are is high.	1 year Follow up
Secondary	Functional Response	Defined as improvement from baseline of greater than or equal to (>=) 7 points on the FROGS scale. FROGS scale: The "Functional Remission of General Schizophrenia" (FROGS) is a 19 items scale gathered in five fields ("Daily life", "Activities", "Adaptation Quality", "relational Life", "Health and treatment") used to evaluate the functional remission in schizophrenia. The 19 items must be scored from 1(not done) to 5 (perfectly done). The total score is 19 to 95. More the score is high, better the functioning abilities are is high.	1 year Follow up
Secondary	Satisfactory Level of Functioning	Defined by the absence of an item less than (<) 3 on the FROGS scale. FROGS scale: The "Functional Remission of General Schizophrenia" (FROGS) is a 19 items scale gathered in five fields ("Daily life", "Activities", "Adaptation Quality", "relational Life", "Health and treatment") used to evaluate the functional remission in schizophrenia. The 19 items must be scored from 1(not done) to 5 (perfectly done). The total score is 19 to 95. More the score is high, better the functioning abilities are is high.	1 year Follow up
Secondary	Predictive Clinical Characteristics	Search for clinical variables predicting an improvement in social performance.	1 year Follow up
Secondary	Threshold Score	Determine a threshold score to define functional remission, satisfactory functioning and optimal functioning on the Mini FROGS scale. Mini FROGS: 4 of the 19 items of FROGS, also scored from 1 (not done) to 5 (perfectly done), the total score is 4 to 20. More the score is high, better the functioning abilities are high.	1 year Follow up
