Clinical Trial Summary

This study is open to adults with different types of advanced cancer. People can take part if previous treatment was not successful, or no treatment exists.

The purpose of this study is to find the highest dose of a medicine called BI 1703880 that people with advanced cancer can tolerate when taken together with ezabenlimab. BI 1703880 and ezabenlimab are medicines that may help the immune system fight cancer. In this study, BI 1703880 is given to people for the first time.

Participants get BI 1703880 and ezabenlimab as infusions into a vein. During the first 6 weeks, they get BI 1703880 once a week. Later, they get BI 1703880 every 3 weeks. After the first 3 weeks, they get ezabenlimab in addition every 3 weeks.

Participants can get BI 1703880 for up to 1 year and ezabenlimab for up to 2 years as long as they benefit from treatment and can tolerate it. During this time, they visit the study site regularly. At these visits, the doctors check participants' health and take note of any unwanted effects.

Eligibility

Inclusion Criteria:

• Histologically or cytologically confirmed diagnosis of an advanced, unresectable and/or metastatic or relapsed/refractory solid tumour. Patient must have at least one measurable lesion (according to Response Criteria in Solid Tumours (RECIST 1.1)).

• Patient must have exhausted or refused established treatment options for the malignant disease, or is not eligible for established treatment options.

• Has a lesion amenable to pre-treatment and on-treatment biopsy and patient consents to both biopsies.

• Medically fit and willing to undergo all mandatory trial procedures.

• Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1.

• Adequate organ function or bone marrow reserve as demonstrated at screening by the following laboratory values:

• Absolute neutrophil count = 1.5x10^9/L (= 1.5x10^3/µL, = 1500/mm3); platelet count = 100x10^9/L (= 100x10^3/µL, = 100x10^3/mm3), without the use of hematopoietic growth factors within 4 weeks of start of trial medication

• Haemoglobin = 90 g/L (= 9.0 g/dL, = 5.6 mmol/L)

• Estimated glomerular filtration rate (eGFR) =60 ml/min/1.73m^2 (as determined by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula)

• Aspartate transaminase (AST) and alanine transaminase (ALT) = 3 x ULN if no demonstrable liver metastases, or otherwise = 5 x ULN if transaminase elevation is attributable to liver metastases.

• Total bilirubin = 1.5 x ULN, except for patients with Gilbert's syndrome: total bilirubin = 3.0 x ULN or direct bilirubin = 1.5 x ULN

• partial thromboplastin time (PTT) / activated partial thromboplastin time (aPTT) <1.5 x ULN

• Patients =18 years of age or over the legal age of consent in countries where that is greater than 18 years at the time of signature of the informed consent form (ICF).

• Signed and dated written ICF in accordance with International Council for Harmonisation- Good Clinical Practice (ICH-GCP) and local legislation, obtained before performing any protocol related procedures that are not part of normal standard of practice care. Note: If a patient declines to participate in the voluntary biobanking component of the trial, he/she will not be excluded from other aspects of the trial.

Further inclusion criteria apply

Exclusion Criteria:

• Any investigational or antitumour treatment within 4 weeks or 5 half-life periods prior to the first treatment whichever is shorter.

• Prior STING agonist therapy.

• Prior intolerability of a anti-programmed cell death protein 1 (PD-1) or anti-programmed cell death ligand 1 (PD-L1) therapy.

• History of allergy or hypersensitivity to study agent components.

• Immunosuppressive therapies including, but not limited to, systemic corticosteroids at doses exceeding >10 mg/day of prednisone or equivalent, and tumour necrosis factor-alpha blockers.

• Persistent toxicity from previous treatments (including immune related Adverse Events (irAEs)) that has not resolved to Grade =1, except for alopecia, xerostomia, and immunotherapy related endocrinopathies.

• Evidence of active, non-treatment related autoimmune disease, except for endocrinopathies.

• History or complication of pneumonitis or interstitial lung disease within the last 12 months, or any prior pneumonitis related to immunotherapy.
