A Phase Ia/Ib, Open-label, Multicentre Dose-escalation and Expansion Study to Investigate the Safety, Pharmacokinetics and Preliminary Efficacy of BI 1823911 as a Monotherapy and in Combination With Other Anti-cancer Therapies in Patients With Advanced or Metastatic Solid Tumours Expressing KRAS G12C Mutation

Summary

This study is open to adults with different types of advanced or metastatic cancer (including lung cancer, colorectal cancer, pancreatic cancer, and bile duct cancer). This study is for people for whom previous treatment was not successful or no treatment exists.

People who have a tumour with a KRAS mutation can participate in the study. A KRAS mutation makes tumours grow faster. BI 1823911 and BI 1701963 are medicines that may turn off KRAS, each in a different way. In this study, BI 1823911 is given to people for the first time.

The purpose of this study is to find the highest dose of BI 1823911 that people can tolerate when taken alone and together with BI 1701963. The most suitable dose is used to find out whether BI 1823911 alone and in combination with BI 1701963 can make tumours shrink.

Participants can stay in the study as long as they benefit from treatment and can tolerate it.

During this time, participants take tablets of BI 1823911 alone or in combination with BI 1701963 once a day. The doctors regularly monitor the size of the tumour. Doctors also regularly record any unwanted effects and check participant's health.

Eligibility

Yes No Not Sure

Inclusion Criteria

Pathologically confirmed diagnosis of locally advanced or metastatic solid tumours, e.g. adenocarcinoma of the lung, colorectal cancer, pancreatic cancer or cholangiocarcinoma. Non-small cell lung cancer (NSCLC) patients with mixed histology are eligible if adenocarcinoma is the predominant histology
Documented disease progression despite appropriate prior standard therapies or for whom no standard therapy exists for their tumour type and disease stage
KRAS mutation status: Kirsten rat sarcoma virus homolog (KRAS) glycine-to-cysteine (G12C) mutation in tumour tissue or blood based on previously performed local testing using a validated test
Provision of archival tumour tissue, if available, to confirm retrospectively KRAS G12C mutation status and for biomarker assessment
At least one target lesion that can be measured per Response Evaluation Criteria In Solid Tumours (RECIST) version 1.1 (radiated lesions do not qualify as target lesions). In patients who only have one target lesion, and a biopsy of the lesion is required, the baseline imaging must be performed before the biopsy or at the earliest two weeks after the biopsy
Absolute neutrophil count (ANC) ≥1.5 x 10^9/L (equivalent values: ≥ 1.5 x 10³/μL or ≥ 1500/mm³); hemoglobin ≥9.0 g/dL (equivalent values: ≥ 90 g/L or ≥ 5.6 mmol/L); platelets ≥100 x 10^9/L (equivalent values: ≥ 100 x 10³/μL or ≥ 100 x 10³/mm³) without the use of haematopoietic growth factors
Total bilirubin ≤1.5 times the upper limit of normal (ULN), or ≤4 x ULN for patients who are known to have Gilbert's syndrome
Creatinine ≤1.5 x ULN. If creatinine is >1.5 x ULN, patient is eligible if concurrent creatinine clearance ≥50 mL/min (equivalent value: 0.84mL/s) (measured or calculated by Cockcroft-Gault formula)
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Aspartate transaminase (AST) and alanine transaminase (ALT) ≤3 x ULN, for patients with liver metastases ≤5 x ULN
Age ≥18 years of age, or over the legal age of consent as required by local
Adequate organ function as follows
legislation
Further inclusion criteria apply

Exclusion Criteria

Previous anticancer chemotherapy within 3 weeks of the first administration of trial drug. Previous anticancer hormonal treatment or anticancer immunotherapy within 2 weeks of the first administration of trial drug
Previous treatment with Rat Sarcoma (RAS), Mitogen-activated protein kinase (MAPK) or Son of sevenless 1 (SOS1) targeting agents (only for monotherapy Parts A, B, and C)
Radiotherapy within 2 weeks prior to start of treatment, provided recovery from related toxicity
Major surgery (major according to the investigator's assessment) performed within 4 weeks prior to start of treatment or planned during the projected course of the trial, e.g. hip replacement
Previous treatment with any investigational agent(s) or targeted treatment within 28 days prior to start of treatment or 5 half-lives, whichever is shorter
Known history of hypersensitivity to any of the excipients of BI 1823911 tablets, or any contraindication to Midazolam (for Monotherapy Part B only)
History or presence of cardiovascular abnormalities such as congestive heart failure New York Heart Association (NYHA) classification of ≥3, unstable angina or poorly controlled arrhythmia which are considered clinically relevant by the Investigator. Myocardial infarction within 6 months prior to start of treatment. Uncontrolled hypertension defined as: Blood pressure (BP) measured in a rested and relaxed condition, where systolic BP >=140 mmHg, or diastolic BP >= 90 mmHg, with or without medication
Left ventricular ejection fraction (LVEF) <50%. Further exclusion criteria apply
