摘要: PURPOSETo determine the toxicity, pharmacokinetics, response rate, and duration of intravenous (i.v.) administration recombinant, humanized anti-p185HER2 monoclonal antibody (rhuMAb HER2) plus cisplatin (CDDP) in a phase II, open-label, multicenter clinical trial for patients with HER2/neu-overexpressing metastatic breast cancer.PATIENTS AND METHODSThe study population consisted extensively pretreated advanced cancer HER2/neu overexpression disease progression during standard chemotherapy. Patients received loading dose rhuMAb HER2 (250 mg i.v.) on day 0, followed by weekly doses 100 i.v. 9 weeks. CDDP (75 mg/m2) days 1, 29, 57.RESULTSOf 37 assessable response, nine (24.3%) achieved PR, had minor or stable disease, occurred 19 (51.3%). The median was 5.3 months (range, 1.6-18). Grade III IV toxicity observed 22 39 (56%). T...
