Clinical Trial of BI 425809 Effect on Cognition and Functional Capacity in Schizophrenia (CONNEX-3)
Study Details
Study Description
Brief Summary
This study is open to adults with schizophrenia. Schizophrenia can affect the way a person thinks, their memory and their mental functioning. Examples include struggling to remember things, or to read a book or pay attention to a movie. Some people have difficulty calculating the right change or planning a trip so that they arrive on time. The purpose of this study is to find out whether a medicine called BI 425809 improves learning and memory in people with schizophrenia.
Participants are put into two groups randomly, which means by chance. One group takes BI 425809 tablets and the other group takes placebo tablets. Placebo tablets look like BI 425809 tablets but do not contain any medicine. Participants take a tablet once a day for 26 weeks. In addition, all participants take their normal medication for schizophrenia.
During this time, doctors regularly test learning and memory of the participants by use of questionnaires, interviews, and computer tests. The results of the mental ability tests are compared between the groups.
Participants are in the study for about 8 months and visit the study site about 14 times. During this time, doctors regularly check participants' health and take note of any unwanted effects.

Outcome Measures
Primary Outcome Measures
- Change from baseline in overall composite T-score of the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) consensus cognitive battery (MCCB) [After 26 weeks of treatment]
MCCB 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
Secondary Outcome Measures
- Change from baseline in the Schizophrenia Cognition Rating Scale (SCoRS) interviewer total score [After 26 weeks of treatment]
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. Higher ratings reflect a greater degree of impairment.
- Change from baseline to Week 26 in the adjusted total time in the Virtual Reality Functional Capacity Assessment Tool (VRFCAT) [Up to week 26]
- Change from baseline to Week 26 in the T-score of the number of correct responses on Tower of London [Up to week 26]
- Change from screening visit 1a to Week 24 in Patient Reported Experience of Cognitive Impairment in Schizophrenia (PRECIS) total score [Up to week 24]
PRECIS is a patient reported outcome (PRO) for recording patients' subjective experience of Cognitive Impairment Associated with Schizophrenia (CIAS). The questionnaire contains 28 items covering 6 domains: Memory (6 items), communication (4 items), self-control (3 items), executive function (4 items), attention (6 items), and sharp thinking (3 items). Two additional items assess the overall degree of bother associated with all domains. Questions are answered via a 5-category Likert scale, with higher scores corresponding to worse patient experience. The Total Score is derived by calculating the simple average score of the first 26 items.
