Detailed Description
This is a phase Ⅲ, double-blind, randomized, parallel-controlled, multicenter equivalence study to compare the efficacy and safety of SYSA1901 + trastuzumab + docetaxel vs. Perjeta® + trastuzumab + docetaxel in the patients with early-stage or locally advanced HER2-positive and HR-negative breast cancer with a primary tumor > 2 cm. The eligible patients will be randomized to treatment group (SYSA1901 + Trastuzumab + Docetaxel) or control group (Perjeta® + Trastuzumab + Docetaxel) at 1:1 ratio. The stratification factor is disease category (early-stage vs. locally advanced).
The primary endpoint is total pCR (tpCR). Secondary efficacy endpoints include breast pCR (bpCR), objective response rate (ORR),pharmacokinetic (PK) and immunogenicity.
