Brief Summary

This is a study in people between 16 and 30 years of age who have a specific type of mental illness called attenuated psychosis syndrome (APS). The purpose of this study is to find out whether BI 409306 helps reduce the symptoms of APS.

Participants are in the study for 1 year and 2 months. During this time, they visit the study site about 15 times and get about 10 phone calls. Participants are put into 2 groups by chance. They get either BI 409306 or placebo. Placebo tablets look like BI 409306 tablets but do not contain any medicine. Participants take a BI 409306 or placebo tablet two times a day.

During the study, participants answer questions in interviews and complete questionnaires so the doctors can check whether the APS symptoms change. The doctors also check the general health of the participants.

BI 409306BI 409306Patients meeting Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) diagnostic criteria for attenuated psychosis syndrome (APS) per the Structured Interview for Psychosis-Risk Syndromes (SIPS) took 50 milligrams BI 409306, as a film-coated tablet, orally twice a day at approximately the same time every day in the morning and in the evening (approximately 12 hours apart) with or without food for 52 weeks.
PlaceboPlaceboPatients meeting Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) diagnostic criteria for attenuated psychosis syndrome (APS) per the Structured Interview for Psychosis-Risk Syndromes (SIPS) took placebo matching 50 milligrams BI 409306, as a film-coated tablet, orally twice a day at approximately the same time every day in the morning and in the evening (approximately 12 hours apart) with or without food for 52 weeks.
Primary Outcome Measures
NameTimeMethod
Incidence of Remission From Attenuated Psychosis Syndrome (APS) Within a 52-week TimeframeUp to 52 weeks.

Incidence of remission from attenuated psychosis syndrome (APS) within a 52-week timeframe. The incidence rate per patient-years of remission from attenuated psychosis syndrome (APS) is reported. Remission from APS is defined as a score of \<3 on all of the five Positive Symptom items of the Scale of Prodromal Symptoms (SOPS) and maintained until the end of treatment. The SOPS provides a 6-point scale (minimum of 0 and maximum of 6, higher score indicating worse symptoms) to quantitatively rate the severity of five attenuated positive symptoms. incidence rate = number of events/total time at risk \[patient-years\].

Secondary Outcome Measures
NameTimeMethod
Incidence of First Episode of PsychosisUp to 52 weeks.

Incidence of first episode of psychosis. The incidence rate per patient-years of psychosis is reported, psychosis is defined as one or more positive Scale of Prodromal Symptoms (SOPS) symptoms rated a 6 AND either a symptom is seriously disorganizing or dangerous OR one of the symptoms above occurred at least one hour per day at an average frequency of four days/week over the past month. OR a new prescription or increase in dose of an ongoing antipsychotic medication. The SOPS provides a 6-point scale (minimum of 0 and maximum of 6, higher score indicating worse symptoms) to quantitatively rate the severity of five attenuated positive symptoms.

Change From Baseline in Everyday Functional Capacity as Measured by Schizophrenia Cognition Rating Scale (SCoRS) Total Score After 24 and 52 Weeks of TreatmentBaseline, week 24 and week 52.

Change from baseline (Day -28 to -7) in everyday functional capacity as measured by Schizophrenia Cognition Rating Scale (SCoRS) total score after 24 and 52 weeks of treatment. 20-item assessment of cognitive deficits and the degree to which they affect day-to-day functions. Each of the 20 items of the SCoRS is rated on a 4-point scale (minimum of 1 and maximum of 4). Higher ratings reflect a greater degree of impairment. The composite score will be the sum of the 20 items (minimum of 20 and maximum of 80). Data analyzed using the restricted maximum likelihood (REML) mixed effects model with repeated measurements (MMRM) including fixed, categorical effects of treatment, visit, treatment by visit interaction, baseline North American Prodromal Longitudinal Study (NAPLS) risk score, baseline use of antipsychotic medication and continuous fixed covariates of baseline score and baseline-by-visit interaction.

Change From Baseline in the Tablet Based Brief Assessment of Cognition (BAC App) Composite T Score After 52 Weeks of TreatmentBaseline and week 52.

Change from baseline (Day -28 to -7) in the tablet based Brief Assessment of Cognition (BAC App) composite T score after 52 weeks of treatment. The BAC consists of five tests assessing multiple domains of cognitive function: Verbal Memory, Digit Sequencing, Semantic and Letter Fluency, Symbol Coding, and Tower of London. A composite T score that is calculated using the five standardized scaled sub-test scores was generated (averages five of the standardized scaled sub-test scores, token motor test score not included), larger T-score indicates better cognition. Data analyzed using the REML MMRM including fixed, categorical effects of treatment, visit, treatment by visit interaction, baseline North American Prodromal Longitudinal Study (NAPLS) risk score, baseline use of antipsychotic medication and continuous fixed covariates of baseline score and baseline-by-visit interaction. T-scores in the general population have a mean of 50 and standard deviation of 10.

Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Positive Items Score, Negative Items Score, and Total Score After 52 Weeks of TreatmentBaseline and week 52.

Change from baseline (Day -28 to -7) in Positive and Negative Syndrome Scale (PANSS) positive items score, negative items score, and total score after 52 weeks of treatment. The PANSS positive and negative symptom scales each have 7 items, and the General Psychopathology Scale (not reported) has 16 items. The patient is rated from 1 to 7 on the 30 different items based on the interview, as well as reports from an informant when possible. Total score is the sum of the score of the 30 items (minimum 30, maximum 210), subtotal are the sum of either the positive or negative scales (minimum 7, maximum 49), lower scores represent an improvement in schizophrenia symptoms. Data analyzed using the REML MMRM including fixed, categorical effects of treatment, visit, treatment by visit interaction, baseline NAPLS risk score, baseline use of antipsychotic medication and continuous fixed covariates of baseline score and baseline-by-visit interaction.
