Study of Antivascular Therapy Combined With Chemotherapy Versus Chemotherapy in Adjuvant Therapy of TNBC-BLIS Patients (BCTOP-T-A03)

A Randomized, Open-label Phase III Clinical Trial Comparing Antivascular Therapy Combined With Standard Chemotherapy and Standard Chemotherapy in Adjuvant Therapy for Patients With Triple-Negative Breast Cancer, Basal-like Immunosuppressed Subtype (BCTOP-T-A03)

This is a randomized, open-label phase III clinical trial comparing antivascular therapy combined with standard chemotherapy and standard chemotherapy in adjuvant therapy for patients with triple-negative breast cancer, basal-like/Immune suppressed subtype.

Inclusion Criteria:

• Women aged 18-70 years old;

• Adequate hematological and end-organ function as defined by the following laboratory test results, which need to be completed within 28 days prior to the first study treatment: absolute neutrophil count (ANC) ≥ 1500 cells/μL (no G-CSF support therapy within 2 weeks prior to day 1 of course 1); Platelet count ≥ 75×109/L (no platelet transfusion within 2 weeks before day 1 of course 1); hemoglobin ≥ 9.0 g/dL (no RBC transfusion within 2 weeks before day 1 of course 1); AST, ALT, and alkaline phosphatase ≤ 3 × upper limit of normal (ULN) serum total bilirubin ≤ 1.0 × ULN; serum creatinine ≤ 1ULN and with an endogenous creatinine clearance rate of >50 ml/min (Cockcroft-Gault formula);
