This clinical trial is focused on studying treatments for advanced solid tumors, which are types of cancer that have spread beyond their original location. The study involves two medications: BI-1808 and pembrolizumab. BI-1808 is a new treatment being tested, and it is a type of medication known as a monoclonal antibody, which is designed to target specific proteins in the body. Pembrolizumab, also known by its brand name KEYTRUDA, is an existing cancer treatment that helps the immune system fight cancer cells.
The purpose of the study is to evaluate the safety and tolerability of BI-1808 when used alone and in combination with pembrolizumab. Participants will receive these treatments through an intravenous infusion, which means the medication is given directly into a vein. The study will be conducted in phases, starting with testing BI-1808 by itself and then in combination with pembrolizumab. Researchers aim to find the most suitable dose that can be safely given to patients.
Throughout the study, participants will be monitored for any side effects or adverse reactions to the treatments. The study will also look at how the body processes BI-1808 and how it interacts with the immune system. This research is important for understanding how these treatments can be used to help people with advanced cancers and to determine the best way to use them in future treatments.
