Actual date on which the first participant was enrolled.

This clinical trial aims to test a new treatment called JAB-30355 for adults who have advanced solid tumors with a specific genetic change known as the TP53 Y220C mutation. This mutation can make cancer more difficult to treat, so finding effective treatments is important. The study's goal is to see if JAB-30355 is safe and can help fight these types of tumors. It is hoped that this research will lead to better treatment options for patients with these challenging cancers. The study is divided into two parts. In the first part, called the Dose Escalation Phase, participants receive increasing doses of JAB-30355 to find the highest dose that can be safely given. This part helps to assess the safety and how well participants tolerate the treatment. In the second part, the Dose Expansion Phase, more participants will receive JAB-30355 at the doses deemed safe to further investigate its effects and benefits. Results are measured by observing the treatment's impact on the tumors and any side effects experienced by the participants.
