Summary

This trial is for people with schizophrenia who have taken part in previous studies. The purpose is to see if they can tolerate a medicine called BI 425809 in the long term. They take it once a day for a year, plus their normal medication. They have 13 visits and 9 phone calls with the study team.

Who is the study for?
This trial is for adults with schizophrenia who previously participated in a CONNEX study. They must be clinically stable, use effective birth control if applicable, and have a regular caregiver or partner to interact with them. People can't join if they've had repeated positive drug screens, developed conditions other than schizophrenia that would interfere with the trial, or shown severe suicidal behavior recently.
What is being tested?
The study tests the long-term safety of Iclepertin tablets taken daily for one year by people with schizophrenia while continuing their normal medication. Participants will visit the study site approximately 13 times and receive around 9 calls from researchers over slightly more than a year.
What are the potential side effects?
While specific side effects are not listed here, participants' health problems will be monitored throughout the study to assess how well they tolerate Iclepertin over an extended period.
