A Study to Test How Different Doses of BI 1703880 in Combination With Ezabenlimab Are Tolerated in People With Different Types of Advanced Cancer (Solid Tumours)

Официальное название

Phase Ia, First in Human Open Label Dose Escalation Trial Evaluating Intravenous BI 1703880 in Combination With Intravenous Ezabenlimab for Treatment of Advanced Solid Tumours

Обзор

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.

• 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.
