Brief Summary

This study is open to adults with small cell lung cancer and other neuroendocrine cancers. The study is in people with advanced cancer for whom previous treatment was not successful or no standard treatment exists. The purpose of this study is to find out how a medicine called BI 764532 gets distributed in the body and in tumours. Participants get BI 764532 when starting treatment. In the first weeks, doctors check how BI 764532 is taken up in tumours by means of an imaging method. If there is benefit for the participants and if they can tolerate it, the treatment is given up to the maximum duration of the study. During this time, participants visit the study site regularly. The total number of visits depends on how they respond to and tolerate the treatment. Doctors record any unwanted effects and regularly check the general health of the participants.

• Subjects with brain metastases are eligible provided they meet the following criteria:
• radiotherapy or surgery for brain metastases was completed at least 2 weeks prior to the first administration of BI 764532,
• patient is off steroids for at least 7 days (physiologic doses of steroids are permitted), and the patient is off anti-epileptic drugs for at least 7 days or on stable doses of anti-epileptic drugs for malignant CNS disease.

You may not qualify if:

• Previous or concomitant malignancies other than the one treated in this trial within the last 2 years except:
• effectively treated non-melanoma skin cancers
• effectively treated carcinoma in situ of the cervix
• effectively treated ductal carcinoma in situ
• other effectively treated malignancy that is considered cured by local treatment
• Major injuries and/or surgery or bone fracture within 28 days of first dose BI 764532, or planned surgical procedures
• Known leptomeningeal disease or spinal cord compression due to metastatic disease
• Anticoagulant treatment that cannot be safely interrupted based on opinion of the investigator if medically needed
• Active infection that requires medical therapy or other clinically significant intervention
• Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection within 2 weeks prior to study entry (confirmed via polymerase chain reaction (PCR) test or other applicable test as per local requirements) or suspected SARS-CoV-2 infection as per physician assessment, or close contact (within 1 week) with an individual with confirmed SARS-CoV-2 infection
• Any of the following known laboratory evidence of hepatitis virus infection:
• Positive results of hepatitis B surface (HBs) antigen
• Presence of hepatitis B core (HBc) antibody together with hepatitis B virus DNA (HBV-DNA)
