Ideal candidates include adults aged 18 and older with metastatic or inoperable locally advanced breast cancer who meet specific eligibility criteria.

Probably not a fit

Patients with early-stage breast cancer or those who have already received multiple lines of treatment may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the efficacy and safety of various treatment combinations in patients with metastatic or locally advanced breast cancer. It consists of two stages, with four cohorts focusing on different patient populations based on their previous treatments and tumor characteristics. Participants will receive treatments such as Capecitabine, Atezolizumab, and others, depending on their cohort classification. The study aims to determine the best therapeutic strategies for these challenging cases of breast cancer.

Why it matters

Potential benefit: If successful, this study could provide new effective treatment options for patients with advanced breast cancer.

How similar studies have gone: Other studies have shown promise with similar treatment combinations in advanced breast cancer, indicating potential for success in this approach.
