Study Summary

This trial is testing a new drug, ZEN003694, in combination with an existing drug, Talazoparib, in patients with Triple-Negative Breast Cancer (TNBC) who do not have BRCA1 or BRCA2 mutations. The trial has two parts: a dose escalation part to find the best dose of the new drug, and a Simon 2-Stage design part to test how well the combination works. There are three expansion cohorts testing different aspects of the combination.
