We aimed to evaluate the efficacy of weekly nab-paclitaxel compared with the standard regimen of docetaxel plus carboplatin, both with trastuzumab and pertuzumab, as neoadjuvant therapies for patients with HER2-positive breast cancer. Between Sept 20, 2020, and March 1, 2023, 689 eligible patients were randomly assigned. All 689 patients were Asian women. 669 patients received at least one dose of the study treatment and were included in the full analysis set (332 in the nab-paclitaxel group and 337 in the docetaxel plus carboplatin group). Median age of the patients was 50 years (IQR 43-55). Median follow-up time was 26 months (IQR 19-32). 220 (66·3%) patients in the nab-paclitaxel group had a pathological complete response, compared with 194 (57·6%) in the docetaxel plus carboplatin group (combined odds ratio 1·54; stratified p=0·011). 100 (30%) patients in the nab-paclitaxel group and 128 (38%) in the docetaxel plus carboplatin group had grade 3-4 adverse events. The most common grade 3-4 adverse events were nausea (22 [7%] in the nab-paclitaxel group vs 76 [23%] in the docetaxel plus carboplatin group), diarrhoea (25 [8%] vs 55 [16%]), and neuropathy (43 [13%] vs eight [2%]). No treatment-related deaths were reported in either group. These findings might suggest a potential advantage of nab-paclitaxel combined with trastuzumab and pertuzumab compared with the standard regimen in neoadjuvant therapy for patients with HER2-positive early breast cancer, suggesting that this new combination might establish a new standard for neoadjuvant treatment in this patient population.
