Eribulin Mesylate as Second-Line Therapy for Locally Advanced, Unresectable, or Metastatic Pancreatic Cancer Patients

PRIMARY OBJECTIVE: I. To determine the objective response (complete and partial) to E7389 in patients with locally advanced, unresectable, or metastatic pancreatic adenocarcinoma that progressed after prior gemcitabine hydrochloride-based therapy. SECONDARY OBJECTIVE: I. To determine the antitumor activity of E7389, in terms of median survival, 1-year survival rate, response or stable disease duration, toxicity, and time to disease progression, in these patients. OUTLINE: This is an open-label, multicenter study. Patients receive eribulin mesylate IV on days 1 and 8. Treatment repeats every 3 weeks in the absence of disease progression or unacceptable toxicity. After completion of study treatment, all patients are followed at 4 weeks. Patients with complete response, partial response, or stable disease are followed every 3 months.
