Summary

The goal of this trial is to learn if KQB548 works to treat patients with advanced solid malignancies with a KRAS G12D mutation. It will also learn about the safety of KQB548. The main questions it aims to answer are: * What is the safe dose of KQB548? * Does KQB548 decrease the size of the tumor? * What happens to KQB548 in the body?
