Testing the Addition of an Investigational Anti-Cancer Drug, ASTX660 (Tolinapant), to a Usual Chemotherapy Treatment (Eribulin) for Treatment of Advanced Triple Negative Breast Cancer

• Status: WITHDRAWN
• Trial end date: 2027-05-17

Summary

This phase I/Ib trial tests the safety, side effects, best dose, and effectiveness of ASTX660 (tolinapant) in combination with eribulin mesylate (eribulin) in treating patients with triple negative breast cancer that cannot be removed by surgery (unresectable) or that has spread to nearby tissues or lymph nodes (locally advanced) or to other places in the body (metastatic). Tolinapant may stop the growth of tumor cells by blocking proteins, such as XIAP and cIAP1, needed for tumor cell survival. Chemotherapy drugs, such as eribulin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving tolinapant in combination with eribulin may be safe, tolerable, and/or effective in treating patients with unresectable, locally advanced, or metastatic triple negative breast cancer.
