First seen Nov 01, 2025 · Last updated May 16, 2026 · Updated 26 times

Summary

This study tests whether a combination of two drugs, talazoparib and temozolomide, can shrink advanced rare cancers or stop them from growing. The trial includes 14 adults with rare solid tumors that have not responded to standard treatments. Talazoparib blocks a protein that helps cancer cells repair their DNA, while temozolomide damages cancer cell DNA directly, aiming to kill the cells together.
