What this trial studies

This study aims to evaluate the efficacy and safety of a combination of capecitabine and cyclophosphamide (XC) compared to the physician's choice of treatment as maintenance therapy for patients with advanced breast cancer who have achieved disease control after salvage treatment. The trial will involve female participants aged 18 and older with confirmed recurrent or metastatic breast cancer. Patients must have at least one measurable lesion and demonstrate adequate organ function to be eligible for the study.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18 and older with advanced breast cancer who have achieved disease control after previous treatments.

Not a fit: Patients with central nervous system metastasis or those who are pregnant or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective maintenance therapy option for patients with advanced breast cancer.

How similar studies have performed: While there have been various studies on maintenance therapies for breast cancer, the specific combination of capecitabine and cyclophosphamide as maintenance therapy is relatively novel.
