Inclusion Criteria:

  • Signed and dated written informed consent in accordance with ICH Harmonized Tripartite Guideline for Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial.

  • Established schizophrenia (as per DSM-5) with the following clinical features:

    • Outpatient, with no hospitalization for worsening of schizophrenia within 3 months prior to randomization
    • Psychiatrically stable without symptom exacerbation within 3 months prior to randomization
    • PANSS score ≤ 5 on positive items P1, P3-P7 and ≤ 4 on positive item P2 at Visit 1, and confirmed at Visit 2
  • Patients must be on stable antipsychotic treatment, and current antipsychotic and concomitant psychotropic medications must meet the criteria below:

    • Patients may take up to 2 antipsychotics (typical and/or atypical), except for clozapine
    • Patients must be stable on current antipsychotics and concomitant psychotropic medications (e.g. anticholinergics, antiepileptics, lithium and allowed antidepressants) for at least 3 months prior to randomization and be on current dose for at least 30 days prior to randomization ---Patients on Long-Acting Injectable (LAI) antipsychotics should be on the same medication and dose for at least 3 months prior to randomization
  • Women of childbearing potential (WOCBP)2 must be ready and able to use highly effective methods of birth control per Non-Clinical Safety Studies for the Conduct of Human Clinical Trials and Marketing Authorization for Pharmaceuticals (ICH M3 (R2)) that result in a low failure rate of less than 1% per year when used consistently and correctly. Such methods should be used throughout the trial, and for a period of at least 35 days after last trial drug intake, and the patient must agree to periodic pregnancy testing during participation in the trial.
  • Patients must demonstrate their ability to properly use the computerized cognitive training (CCT) device and program, as well as be compliant with CCT run-in (defined as completing at least 2 hours per week for two weeks, totalling 4 hours CCT, during the screening period).
  • Patients must be able to comply with all protocol procedures including the at-home CCT exercises, in the investigator's opinion.
  • Patients must have a study partner who will preferably be consistent throughout the study. It is recommended that the study partner should interact (in-person or telephone) with the subject at least 2 times a week.

Exclusion Criteria:

  • Patients who have a categorical diagnosis of another current major psychiatric disorder on the Mini-International Neuropsychiatric Interview (M.I.N.I.).
  • Diseases of the central nervous system (CNS) that may impact the assessment of the cognitive tests as per investigator's opinion.
  • A movement disorder due to antipsychotic treatment not currently controlled with anti- EPS treatment or another movement disorder (e.g. Parkinson´s disease).
  • Patients with a history of participating in any formal cognitive remediation program for 10 or more training sessions.
  • Patients who were treated with any of the following medications within the last 6 months prior to randomization:

    • Bitopertin, BI 409306, encenicline or other investigational drug testing effects on cognition in schizophrenia
    • Clozapine (atypical antipsychotic medication)
    • Sarcosine, cycloserine, serine and glycine
    • Stimulants (e.g. methylphenidate, dextroamphetamine, modafinil)
    • 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.

  • Any of the following, in the judgment of the investigator:

    • Clinically significant finding of the physical examination, vital signs (including blood pressure (BP) and pulse rate (PR)), ECG or laboratory value (as measured by the central laboratory) that would jeopardize the patient's safety while participating in the trial or their capability to participate in the trial.
    • Symptomatic/unstable/uncontrolled or clinically relevant concomitant disease or any other clinical condition that would jeopardize the patient's safety while participating in the trial or capability to participate in the trial.
    • Significant or unstable physical condition that may require change in medication or hospitalization that would impact cognitive function, or planned elective surgery requiring general anesthesia during the study period.
    • Patients for which cognitive or other impairment (including severe hearing impairment) or symptom severity compromises the ability to perform the CCT or assessments related to cognitive outcome measures.
  • Severe renal impairment defined as an eGFR < 30mL/min/1.73m² in the Visit 1 central lab report.

Note: Patients testing positive for cannabis on urine drug screen at Visit 1 may be re-tested once if there is a reasonable explanation and expectation that the patient will not test positive again on re-test, and at the discretion of the investigator.
  • Patients who are not fluent in the language of the batteries/questionnaires which will be used in the country.
  • Patient who did not make an effortful attempt to complete the cognition battery at Visit 1 in the clinical judgement of the investigator.
  • Patients that previously received treatment in any study with BI 425809.
