About

It is a phase III trial to explore the efficacy and safety of metronomic chemotherapy with Capecitabine versus intermittent Capecitabine as maintenance therapy following first-line Capecitabine plus Docetaxel chemotherapy in treatment of HER2-negative metastatic breast cancer(mBC).

Enrollment: 280 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

• Previously untreated first-line chemotherapy.
• Patients with at least one measurable lesion according to RECIST criteria at study entry.
• Documented ER/PgR status.
• Prior hormone therapy for metastatic disease is allowed but must stop before study entry.
• KPS>70.
