First seen Nov 01, 2025 · Last updated May 15, 2026 · Updated 31 times

Summary

This study tested a combination of two drugs, ZEN003694 and talazoparib, in people with triple-negative breast cancer who do not have BRCA gene mutations. The goal was to see if the combination could shrink tumors or slow the disease. The trial was terminated early, so results are limited.
