Results from the phase Bismuth Subcitrate Potassium I portion (n?=?9) demonstrated that the regimen was well tolerated and resulted in an ORR of 33%, including 1 complete response [49]. Discussion Recent clinical data indicate that em nab /em -paclitaxel is effective and safe across all stages of breast cancer. The results from trials in the neoadjuvant setting for early-stage TNBC Bismuth Subcitrate Potassium or HER2-positive breast cancer were particularly encouraging. In TNBC, em nab /em -paclitaxel monotherapy or in combination with other agents resulted in pCR rates ranging from 10.5 to 62%. In the phase III neoadjuvant GeparSepto trial, the largest difference in pCR was identified for patients with TNBC ( em nab /em -paclitaxel, 48.2% vs paclitaxel, 26.3%; em P /em ? ?0.001), supporting the clinical benefit of em nab /em -paclitaxel in early-stage TNBC [11]. The unmet need for the treatment of Bismuth Subcitrate Potassium TNBC lends greater importance to these findings. Patients with early-stage HER2-positive breast cancer also benefited from em nab /em -paclitaxel treatment. Neoadjuvant em nab /em -paclitaxel combined with trastuzumab and carboplatin, anthracycline, or vinorelbine demonstrated pCR rates in the breast and lymph nodes ranging from 45 to 49%, which is comparable to those observed for other current neoadjuvant therapies [50]. In addition, neoadjuvant em nab /em -paclitaxel resulted in breast-conserving surgery in 71 to 77.5% of patients with early-stage breast cancer. In the phase III CALGB 40502 study, patients with MBC treated with first-line em nab /em -paclitaxel plus bevacizumab achieved a median PFS of approximately 9?months and a median OS of 23.5?months [30]. For reference, patients with MBC who received em nab /em -paclitaxel 260?mg/m2 q3w as first- or later-line therapy in a phase III trial demonstrated a median time to tumor progression of 5.3?months and a median OS of 15.0?months [5]. Neither PFS nor OS for the em nab /em -paclitaxel plus bevacizumab arm of the CALGB 40502 trial was significantly different from that of the paclitaxel plus bevacizumab arm [30].
