Albumin-Bound Paclitaxel Combined With Antiangiogenic Agents in First-line Treatment of Relapsed or Metastatic TNBC

This is a prospective, randomized, open-label clinical study. 128 patients with relapsed or metastatic triple-negative breast cancer (TNBC) who had not been systematically treated are going to be enrolled and randomly assigned to 3 groups. Group A: albumin-bound paclitaxel (260mg/m2, intravenous infusion, once every 3 weeks). Group B: albumin-bound paclitaxel (260mg/m2, intravenous infusion, once every 3 weeks)+ apatinib mesylate tablet (500 mg, orally, once daily, every 3 weeks). Group C: albumin-bound paclitaxel (260mg/m2, intravenous infusion, once every 3 weeks) + bevacizumab (7.5mg/kg, intravenous infusion, once every 3 weeks). The dosages of therapeutic drugs are allowed to be adjusted appropriately according to the toxic reaction of the patients. Patients in three groups continued to take medication until disease progression/death/toxicity was intolerable/the patient or investigator decided to discontinue the medication. The primary endpoint is progression-free survival (PFS). Secondary endpoints are objective response rate (ORR), clinical benefit rate (CBR, complete response (CR)+ partial response (PR) + stable disease (SD, \> 6 months)), overall survival (OS), adverse events (AE), and potential predictive biomarker parameters related to treatment response (VEGF-A expression level) in peripheral blood.
