Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with unresectable, locally advanced or metastatic TNBC who meet specific treatment history criteria.

Probably not a fit

Patients with early-stage triple-negative breast cancer or those who have not received prior systemic therapy for advanced disease may not benefit from this study.

What this trial studies

This clinical study aims to evaluate the safety and tolerability of sacituzumab govitecan-hziy (SG) administered at an alternative dose and schedule in patients with advanced triple-negative breast cancer (TNBC). The study consists of two phases: Phase 1 focuses on assessing the preliminary safety, tolerability, pharmacokinetics, and efficacy of SG, while Phase 2 will further investigate these aspects in a larger cohort. The primary objectives include measuring the objective response rate and progression-free survival among participants.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced triple-negative breast cancer who have limited therapeutic alternatives.

How similar studies have gone: Other studies have shown promise with similar approaches in treating advanced triple-negative breast cancer, but this specific dosing schedule is novel.
