What this study is about

This trial is testing if talazoparib, a drug that blocks PARP (a protein involved in DNA repair), can help people with advanced cancer who have changes in their DNA repair genes. The goal is to see if this treatment can stop cancer cells from repairing damaged DNA, leading to cell death. It may also help scientists understand how different PARP inhibitors might work together for some patients.
