- Brief Summary
This is a study in adults with schizophrenia. The study tests whether a medicine called BI 425809 together with brain training improves mental abilities.
Participants take study medication once a day for 12 weeks. At the start of the study, the participants are put into 2 groups. It is decided by chance who gets into which group. One group gets BI 425809 tablets every day. The other group gets placebo tablets every day. Placebo tablets look like the BI 425809 tablets, but contain no medicine. During the study, all participants do brain training using a computer.
The doctors regularly test mental abilities of the participants. The results of the mental ability tests are compared between the groups. The doctors also check the general health of the patients.

- Tricyclic antidepressants
-
Patients receiving any other investigational drug (other than a potential cognitive enhancing drug) within 30 days or 6 half-lives (whichever is longer) prior to randomization. For investigational LAI antipsychotics, the last injection must be at least 3 months or two administration cycles (i.e. 6 months if administration is every 3 months) prior to randomization, whichever is longer.
-
Patients who have participated in a clinical trial with repeated assessments (i.e. a single assessment is not exclusionary) with the MATRICS Consensus Cognitive Battery (MCCB) within the last 6 months prior to randomization.
-
Patients who required a change in ongoing benzodiazepine or sleep medication dose or regimen within the last 30 days prior to randomization.
-
Patients with known active infection with SARS-CoV-2 within the last 30 days prior to randomization.

- Primary Outcome Measures
Name Time Method Change From Baseline in Neurocognitive Function as Measured by the Neurocognitive Composite Score of the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) After 12 Weeks of Treatment At screening (28 days prior to first drug drug administration), at baseline and at Weeks 6 and 12 after first drug administration. MCCB neurocognitive composite T-score assesses 6 cognitive domains, including speed of processing, attention vigilance, working memory, verbal learning, visual learning, reasoning and problem solving. MCCB neurocognitive T-scores in the general population have a mean of 50 and standard deviation of 10. A higher T-score indicates better cognition. Change from baseline in MCCB neurocognitive composite T-score at Week 12 was modelled based on a restricted maximum likelihood (REML) based approach using a mixed model with repeated measurements (MMRM) which included the following fixed effects: categorical factor of planned treatment, visit (screening, baseline, week 6 and Week 12), planned treatment by visit interaction, continuous covariate of baseline value, baseline by visit interaction, categorical factor of age group, and continuous covariate of change from screening to baseline value. The Least Squares Mean (95 % Confidence Interval) at Week 12 is reported.
- Secondary Outcome Measures
Name Time Method Change From Baseline in Cognitive Function as Measured by the Overall MCCB Composite T Score (Including Social Cognition) After 12 Weeks of Treatment At screening (28 days prior to first drug drug administration), at baseline and at Weeks 6 and 12 after first drug administration. MCCB cognitive score comprises 10 tests, which assess 7 cognitive domains, including speed of processing, attention vigilance, working memory, verbal learning, visual learning, reasoning and problem solving, and social cognition. MCCB cognitive T-scores in the general population have a mean of 50 and standard deviation of 10. A higher T-score indicates better cognition. Change from baseline in MCCB overall composite T-score was modelled using a restricted maximum likelihood (REML) based approach using a mixed model with repeated measurements (MMRM) which included the following fixed effects: categorical factor of planned treatment, visit (screening, baseline, week 6 and Week 12), planned treatment by visit interaction, continuous covariate of baseline value, baseline by visit interaction, categorical factor of age group, and continuous covariate of change from screening to baseline value. The Least Squares Mean (95 % Confidence Interval) at Week 12 is reported.
Percentage of Patients With Any Adverse Event (AE) and With Serious Adverse Events (SAEs) From first dose of study drug administration until four weeks after the last dose of study drug administration, up to 16 weeks. Percentage of patients with any Adverse Event (AE) and with serious adverse events (SAEs) is reported.
Percentages were rounded to one decimal place.Change From Baseline in the Effect of Cognitive Deficit on Day-to-day Functioning as Measured by SCoRS Total Score After 12 Weeks of Treatment At baseline and at 12 weeks after first drug administration. Schizophrenia Cognition Rating Scale (SCoRS) is a 20-item interview-based assessment of cognitive deficits and the degree to which they affect day-to-day functioning. Each item is rated on a 4-point scale. SCoRS total score is between 20 and 80 where higher score values represent greater degree of impairment in day-to-day functions due to cognitive deficits. The composite score was the average of non-missing responses. If five or more of the 20 items were missing, the composite score was missing for that participant at the visit.
Change from baseline in SCoRS total score after 12 weeks of treatment was modelled using an Analysis of Covariance (ANCOVA) which included the following fixed effects: categorical factor of planned treatment, continuous covariate of baseline value, categorical factor of age group.Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score After 12 Weeks of Treatment At baseline and at Weeks 6 and 12 after first drug administration. PANSS was used to evaluate broad psychopathology associated with schizophrenia disease state. The PANSS has 30 items. Each is rated from 1 to 7 points. The total factor score is the summation of the actual points for each item, leading the total score ranging from 30 to 210; a higher score indicates a worse disease condition.
Change from baseline in PANNS total score after 12 weeks of treatment was modelled based on a restricted maximum likelihood (REML) based approach using a mixed model with repeated measurements (MMRM) which included the following fixed effects: categorical factor of planned treatment, visit (baseline, Week 6 and Week 12), planned treatment by visit interaction, continuous covariate of baseline value, baseline by visit interaction, categorical factor of age group. The Least Squares Mean (95 % Confidence Interval) at Week 12 is reported.
