Multicenter Phase II Study of Apatinib in Patients With Advanced Breast Cancer(CABC006)

Phase 2

Completed

• Conditions: Breast Cancer
• Interventions: Drug: Apatinib

• Registration Number: NCT02878057
• Lead Sponsor: Peking University Cancer Hospital & Institute

Brief Summary

The treatment of the patients with recurrent and metastatic breast cancer remains a major problem. There is still a lack of effective targeted therapy for Her-2 negative breast cancer.Based on the present researches on the anti-angiogenesis drugs in advanced breast cancer, the investigators believe that it is necessary to further explore the efficacy and safety of apatinib in advanced breast cancer.

Detailed Description

With the comprehensive treatment of breast cancer wildly used in the clinical practice, the life quality of the patients with breast cancer has been improved greatly, and the survival of the patients has been extended as well. However, the treatment of the patients with recurrent and metastatic breast cancer remains a major problem. There is still a lack of effective targeted therapy for Her-2 negative breast cancer.

Based on the present researches on the anti-angiogenesis drugs in advanced breast cancer, the investigators believe that it is necessary to further explore the efficacy and safety of apatinib in advanced breast cancer. The aim of this research is to evaluate the progression-free survival (PFS) of the patients with HER-2 negative advanced breast cancer with chest wall metastasis in the treatment of apatinib.
