A Phase II Trial of TPI 287 in Patients Advanced, Unresectable Pancreatic Cancer

Overview

The primary objective of the study is to assess the activity of TPI 287 as single agent therapy for patients with advanced, unresectable pancreatic cancer after failure of gemcitabine-containing therapy. Activity of TPI 287 will be determined by the 6-month survival rate.

Detailed Description

This is a multicenter, open-label, single arm Phase 2 study in patients with advanced, unresectable pancreatic cancer who have received prior gemcitabine-based chemotherapy for their disease. Patients will receive TPI 287 administered as a 60-minute (± 10 min) IV infusion. The primary endpoint of the trial will be the 6-month survival rate. Additional efficacy endpoints will be response rate, duration of response and stable disease, and 6-month progression free survival. Responses will be assessed by reduction in radiographically measurable disease as defined by the RECIST criteria. Time to worsening of clinical status will be based on reductions in pain and/or analgesic use and changes in tumor markers (CA 19-9) will also be followed. Patients will remain on study until tumor progression or death, unacceptable toxicity, withdrawal of consent or discontinuation based on Investigator discretion. Patients will be followed for survival for up to 1 year after enrollment on the study.

Interventions

  • Drug: TPI 287
    • Intravenous dose of 125 mg/m2 TPI 287 on Day 1, Day 8, and Day 15 in a repeating 28 day cycle.
