Clinical Trial Summary

This is a study in adults from Asia with different types of advanced cancer (solid tumours). People can join the study if they have cancer of the stomach, large bowel and rectum, pancreas, liver, head and neck or non-small cell lung cancer. This is a study for people for whom previous treatment was not successful or no treatment exists. People can participate if their tumour has the B7-H6 marker. The purpose of this study is to find the highest dose of BI 765049 that people with advanced cancer can tolerate when taken (alone and) together with ezabenlimab. Another purpose is to check whether BI 765049 taken (alone and) together with ezabenlimab can make tumours shrink. Both medicines may help the immune system fight cancer. Participants can stay in the study up to 3 years, as long as they can tolerate it and can benefit from it. During this time, they visit the study site about every 3 weeks. At the study site they get BI 765049 alone or in combination with ezabenlimab as an infusion into a vein. BI 765049 is given in 3-week cycles, ezabenlimab is given once every 3 weeks. The doctors check the health of the participants and note any health problems that could have been caused by BI 765049 or ezabenlimab. Doctors regularly check the size of the tumour and check whether it has spread to other parts of the body.

• At least one evaluable target lesion as defined per response evaluation criteria in solid tumors (RECIST v1.1), outside of the central nervous system (CNS), separate from any lesion(s) identified for tumour biopsy. Tumour lesions that have been irradiated =28 days before the start of treatment, and have subsequently had documented progression, may be chosen as target lesions only in the absence of measurable lesions that have not been irradiated.
• Further inclusion criteria apply

Exclusion Criteria:

• History of a major surgery within 28 days prior to first dose of BI 765049 (major according to the Investigator's assessment).
• Presence of other active invasive cancers other than the one treated in this trial within 3 years prior to screening, except for appropriately treated basal cell carcinoma of the skin, in situ carcinoma of the uterine cervix, or other local tumours considered cured by local treatment.
• Known leptomeningeal disease or spinal cord compression due to disease.
• Require anticoagulant treatment which cannot be safely interrupted, if medically needed for a study procedure (e.g., biopsy) based on the opinion of the Investigator.
• Any of the following laboratory evidence of hepatitis virus infection. Test results obtained in routine diagnostics are acceptable for screening if done within 14 days before the ICF2 date: positive results of hepatitis B surface (HBs) antigen, presence of hepatitis B core (HBc) antibody together with hepatitis B virus (HBV)-DNA and presence of hepatitis C-RNA
• Infection requiring systemic antimicrobial, antiviral, antiparasitic, or antifungal therapy at the start of treatment in the trial unless otherwise stipulated.
• Patients with history of human immunodeficiency virus (HIV) infection who meet one or more of the following criteria: cluster of differentiation 4 (CD4)+ count <350 cells/µL, viral load >400 copies/µL, not receiving antiretroviral therapy, receiving established antiretroviral therapy for less than four weeks prior to the start of study treatment, and history of AIDS-defining opportunistic infections within 12 months prior to start of study treatment. Patients with a history of HIV who do not meet any of the criteria above are eligible to participate, but the patient must be under the care of a HIV/Infectious Diseases specialist, or a HIV/Infectious Diseases specialist must be consulted prior to inclusion.
• Previous treatment history: previous treatment in this trial or another trial with a B7-H6 targeting agent, treatment with a systemic anti-cancer therapy or investigational drug within 21 days or 5 half-lives (whichever is shorter) of the first administration of BI 765049, and treatment with extensive field radiotherapy including whole brain irradiation within14 days prior to first administration of BI 765049.
