TODO - Metastatic triple-negative breast cancer lacks a standard therapeutic strategy and represents an unmet need for novel therapies. We conducted a phase II study to evaluate the weekly paclitaxel/carboplatin/bevacizumab combination. Forty-six patients were enrolled and 7 (15.2%) complete and 23 (50%) partial responses were observed for an objective response rate of 65.2% with tolerable toxicity. The combination merits further clinical evaluation. Background: Triple-negative breast cancer (TNBC) lacks a standard targeted therapeutic strategy and is treated with conventional cytotoxic agents. Because of the sensitivity of TNBC to platinum compounds and the synergistic effect of bevacizumab with paclitaxel we investigated the efficacy and toxicity of weekly paclitaxel and carboplatin in combination with bevacizumab as first-line treatment in metastatic TNBC. Patients and Methods: This phase II study followed the Simon's 2-stage optimal design. Paclitaxel (90 mg/m 2 ) and carboplatin (2 area under the curve) were administered on days 1, 8, and 15 every 4 weeks, preceded by bevacizumab 10 mg/kg on days 1 and 15. The primary end point was the objective response rate (ORR). The null hypothesis that the ORR is ≤ 40% could be rejected if the number of objective responses was ≥ 23 among 46 evaluable patients. Results: A total of 46 patients were enrolled. Seven (15.2%) complete and 23 (50%) partial responses were observed for an ORR of 65.2% (95% confidence interval, 52.9%-80.4%). The median progression-free survival was 10.3 months, the median overall survival 25.7 months, and the median duration of response 18.2 months. Neutropenia Grade III and IV was experienced by 13 (28.3%) and 6 (13.04%) patients, respectively. One patient developed an uneventful Grade IV thrombocytopenia. There was 1 toxic death due to febrile neutropenia. Other Grade III toxicities included anemia (n = 2), neurotoxicity (n = 2), thrombocytopenia (n = 1), and diarrhea (n = 1). No serious bevacizumab-related toxicities were observed. Conclusion: The study achieved its primary end point by showing clinical activity for weekly paclitaxel with carboplatin and bevacizumab combination. This regimen merits further evaluation in this setting. © 2017 Elsevier Inc.
