Detailed Description
This study is a multicenter, randomized, open-label, positive-drug parallel-controlled phase II trial. The primary aim of this study was to compare the safety, efficacy, and pharmacokinetics of a dose-dense regimen of bi-weekly WH002 followed by bi-weekly epirubicin and cyclophosphamide (ddWH002-ddEC) versus bi-weekly Paclitaxel® followed by bi-weekly EC (ddP-ddEC) as neoadjuvant treatment in women with HER2-negative high-risk early-stage and locally advanced breast cancer. Patients randomly assigned to ddP-ddEC received premedication with oral prednisolone (12 and 6 hours before paclitaxel), IV dexchlorpheniramine, and cimetidine or ranitidine (30 minutes before paclitaxel). Whereas all of these premedication was not required in the ddWH002-ddEC group before receiving WH002.
Eligible subjects are those with biopsy-confirmed, HER2-negative breast cancer as verified by the research center, and whose tumor staging, as determined by imaging, falls into the categories of early high-risk (T1c-2, N1; T2, N0) or locally advanced (T1c-2, N2-3; T3-4, N0-3). Upon fulfilling all inclusion and exclusion criteria, participants will be randomized in a 1:1 ratio to either the WH002 followed by EC group (Group A) or the Paclitaxel® followed by EC group (Group B).Stratified randomization between the two groups based on tumor molecular subtypes:
- Luminal type (HER2-negative, ER or progesterone receptor positive),
- Triple-negative (HER2-negative, ER and progesterone receptor negative).
