Official title
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
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
