Gemcitabine With or Without WX-671 in Treating Patients With Locally Advanced Pancreatic Cancer That Cannot Be Removed By Surgery

Pancreatic Cancer Clinical Trial

Official title: A Randomized, Open Label, Phase II Proof of Concept Study of WX-671 in Combination With Gemcitabine vs.Gemcitabine Alone in Patients With Locally Advanced, Non Resectable Pancreatic Cancer in Order to Evaluate the Anti-Tumor Activity of the Combination Therapy

Status Completed

Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. WX-671 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving gemcitabine together with WX-671 may kill more tumor cells.

PURPOSE: This randomized phase II trial is studying how well gemcitabine works when given together with WX-671 or when given alone in treating patients with locally advanced pancreatic cancer that cannot be removed by surgery.

Clinical Trial Description

OBJECTIVES:

Primary

• Assess the antitumor activity of two different doses of anti-uPA serine protease inhibitor WX-671 when given in combination with gemcitabine hydrochloride in patients with locally advanced unresectable pancreatic cancer.

• Compare the efficacy, in terms of response rate, progression-free survival, time to first metastasis, overall survival, and tumor and uPA system-related markers, of these regimens in these patients.

• Compare the safety, in terms of vital signs, ECG, biochemistry, hematology (including coagulation), and adverse events, of these regimens.

OUTLINE: This is an open-label, randomized, multicenter study. Patients are randomized to 1 of 3 treatment arms.

• Arm I: Patients receive of oral anti-uPA serine protease inhibitor WX-671 once daily in weeks 1-8 (weeks 1-4 of each subsequent course) and gemcitabine hydrochloride IV over 30 minutes once weekly in weeks 1-7 (weeks 1-3 of each subsequent course) of course 1. All subsequent courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

• Arm II: Patients receive oral anti-uPA serine protease inhibitor WX-671 (at a lower dose than in arm I) once daily in weeks 1-8 (weeks 1-4 of each subsequent course) and gemcitabine hydrochloride IV over 30 minutes once weekly in weeks 1-7 (weeks 1-3 of each subsequent course) of course 1. All subsequent courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

• Arm III: Patients receive gemcitabine hydrochloride IV over 30 minutes once weekly in weeks 1-7 (weeks 1-3 of each subsequent course) of course 1. All subsequent courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. ;
