This study is open to adults with schizophrenia who took part in a previous CONNEX study (study 1346-0011, 1346-0012, or 1346-0013). The purpose of this study is to find out how well people with schizophrenia can tolerate a medicine called BI 425809 in the long term. Participants take BI 425809 as tablets once a day for 1 year. In addition, all participants take their normal medication for schizophrenia. Participants are in the study for a little more than 1 year. During this time, they visit the study site about 13 times and get about 9 phone calls from the study team. The doctors collect information on any health problems of the participants.
