A Phase I Study of Neoadjuvant Chemotherapy With Nab-Paclitaxel, Doxorubicin, and Cyclophosphamide in Patients With Stage II to III Breast Cancer

Micro-Abstract We investigated a novel combinatorial approach using old drugs doxorubicin, cyclophosphamide and nab-paclitaxel in the neoadjuvant setting. Patients were enrolled in Alabama and Utah in a standard 3+3 phase I design. The clinical response rate was 100%; the pathologic complete response (pCR) was over 56%. All 10 patients with triple negative disease (TNBC) achieved pCR (100%). Toxicities were as expected for chemotherapy. This approach warrants further studies in TNBC.
