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.

- Dose escalation (Part A) - Monotherapy and combination therapy: Number of patients experiencing Dose limiting toxicities (DLTs) during the Maximum tolerated dose (MTD) evaluation period for BI 1823911 in monotherapy and in each combination [ Time Frame: up to 28 days ]DLTs are graded according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
- Dose confirmation (Part B) and expansion (Part C) - Monotherapy and combination therapy: Objective response (OR) defined as best overall response (BOR) of confirmed complete response (CR) or confirmed partial response (PR) [ Time Frame: up to 39 months ]
BOR is determined according to Response Evaluation Criteria in Solid Tumours (RECIST) version 1.1.
BOR will consider all tumour assessments from first treatment administration until the earliest of disease progression, death, or last evaluable tumour assessment before start of subsequent anti-cancer therapy, loss to follow-up, or withdrawal of consent.
- Dose escalation (Part A) - Monotherapy and combination therapy: Number of patients experiencing DLTs during all treatment cycles for BI 1823911 in monotherapy and in each combination [ Time Frame: up to 39 months ]
- Dose confirmation (Part B) and expansion (Part C) - Monotherapy and combination therapy: Objective response (OR) [ Time Frame: up to 39 months ]
OR is defined as best overall response (BOR) of complete response (CR) or partial response (PR), both regardless of confirmation.
BOR is determined according to RECIST version 1.1. BOR will consider all tumour assessments from first treatment administration until the earliest of disease progression, death, or last evaluable tumour assessment before start of subsequent anti-cancer therapy, loss to follow-up, or withdrawal of consent.
- Dose confirmation (Part B) and expansion (Part C) - Monotherapy and combination therapy: Duration of OR [ Time Frame: up to 39 months ]Duration of OR is defined as the time from first documented CR or PR until disease progression or death (whichever occurs first) among patients with OR.
- Dose confirmation (Part B) and expansion (Part C) - Monotherapy and combination therapy: Tumour shrinkage (in millimetres) [ Time Frame: up to 39 months ]Tumour shrinkage is defined as the difference between the minimum post-baseline sum of diameters of target lesions (longest for non-nodal lesions, short axis for nodal lesions) and the baseline sum of longest diameters of the same set of target lesions.
- Dose confirmation (Part B) and expansion (Part C) - Monotherapy and combination therapy: Progression-free survival (PFS) rate [ Time Frame: at month 6 ]PFS is defined as the time from first treatment administration until tumour progression according to RECIST version 1.1 or death from any cause, whichever occurs earlier.
- All study parts: Number of patients with adverse events during the on-treatment period [ Time Frame: up to 39 months ]
- All study parts, BI 1823911: Maximum concentration (Cmax) [ Time Frame: up to 24 hours ]
- All study parts, BI 1823911: Steady state concentration (Css) [ Time Frame: up to 24 hours ]
- All study parts, BI 1823911: Area under the plasma concentration-time curve from time zero to time t (AUCτ) [ Time Frame: up to 24 hours ]
- All study parts, BI 1823911: Area under the plasma concentration-time curve at steady state (AUCss) [ Time Frame: up to 24 hours ]
- All study parts, BI 1701963: Maximum concentration (Cmax) [ Time Frame: up to 24 hours ]
- All study parts, BI 1701963: Steady state concentration (Css) [ Time Frame: up to 24 hours ]
