KQB548-101

Details and patient eligibility

About

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?

Enrollment: 78 estimated patients

Sex: All
