Study Summary
This trial is testing whether a medicine called BI 425809 improves learning and memory in people with schizophrenia. People with schizophrenia have difficulty with mental functioning, such as memory and attention. The trial will last 8 months and involve 14 visits to the study site.
Who is the study for?
Adults aged 18-50 with schizophrenia, stable on current antipsychotic treatment (except clozapine), and experiencing functional impairment in daily activities can join. They must not have been hospitalized for worsening schizophrenia recently, use effective birth control if applicable, and have a study partner who meets regularly.Check my eligibility
What is being tested?
The trial tests Iclepertin's effect on cognitive functions like learning and memory in people with schizophrenia over 26 weeks. Participants are randomly assigned to receive either Iclepertin or a placebo alongside their standard medication while undergoing regular mental ability assessments.See study design
What are the potential side effects?
While the specific side effects of Iclepertin are not listed here, participants will be monitored for any unwanted effects throughout the study. Common drug-related side effects could include nausea, headaches, dizziness or sleep disturbances.

Other Research
Common treatments for schizophrenia primarily involve antipsychotic medications, which are divided into typical and atypical antipsychotics. Typical antipsychotics, such as haloperidol, primarily work by blocking dopamine D2 receptors, which helps reduce positive symptoms like hallucinations and delusions.
Atypical antipsychotics, such as clozapine and risperidone, also target dopamine receptors but additionally affect serotonin receptors, which can help with both positive and negative symptoms. The importance of these mechanisms lies in their ability to manage the core symptoms of schizophrenia, thereby improving patients' quality of life.
Cognitive enhancers like Iclepertin, which are being studied for their potential to improve learning and memory, represent a novel approach that could address cognitive deficits in schizophrenia, an area not adequately targeted by traditional antipsychotics.
