A Study Comparing CO-1.01 With Gemcitabine as First Line Therapy in Patients With Metastatic Pancreatic Adenocarcinoma (LEAP)

Metastatic Pancreatic Adenocarcinoma Clinical Trial

Official title: A Phase II Randomized, Open-Label, Multicenter Study Comparing CO-1.01 With Gemcitabine as First-Line Therapy in Patients With Metastatic Pancreatic Adenocarcinoma

Status Completed

Clinical Trial Summary

The purpose of this study is to determine whether CO-1.01 is safe and effective in the treatment of patients with metastatic pancreatic cancer and low hENT1 expression compared with gemcitabine.

Clinical Trial Description

Pancreatic cancer is a very serious form of cancer. The majority of patients present with unresectable disease, and the condition is often not diagnosed until the cancer is relatively advanced. The standard first-line treatment for patients with unresectable pancreatic cancer is gemcitabine monotherapy. Unfortunately many of these patients fail to derive benefit from this treatment. No clinical or molecular marker has been established to predict benefit from gemcitabine therapy, so patients are treated empirically until evidence of disease progression or worsening performance status.

The potential for human equilibrative nucleoside transporter-1 (hENT1) expression to predict survival in gemcitabine-treated patients has been studied, and data suggest that patients with low levels of tumor cell hENT1 expression derive less benefit from gemcitabine treatment than patients with high levels of tumor cell hENT1 expression. These data support the hypothesis to be tested in this study that patients with pancreatic tumors expressing low levels of hENT1 will derive minimal benefit from gemcitabine, but will receive benefit from CO-1.01 (gemcitabine elaidate) which enters tumor cells in a hENT1-independent fashion. ;
