Phase 1 Study of AO-252 for Advanced Solid Tumors

This study is testing a new oral drug called AO-252 in adults with advanced solid tumors, including those with brain metastases. AO-252 is a targeted therapy that works by blocking TACC3 PPI. To join, you must have a solid tumor with a specific genetic change (TP53 mutation/loss) and have already received at least one other treatment. The main goals are to find out how safe AO-252 is, what side effects it might cause, and to determine the best dose for future studies. Researchers will also look for early signs of whether the drug is effective against cancer. This study plans to enroll 86 participants, but its current status is unclear.

Study design
