Patient View

This study evaluates bethanechol's impact on R0 resection rates in pancreatic adenocarcinoma when combined with gemcitabine and nab-paclitaxel. Participants must have pancreatic ductal adenocarcinoma and meet specific criteria. Bethanechol is administered orally, while gemcitabine and nab-paclitaxel follow a set chemotherapy schedule. The study also explores genomic biomarkers and tumor growth reduction.

Patient Parameters

Program Overview

The primary objective of this study is to assess the impact of bethanechol therapy on R0 resection rates. The safety objective will be assessment of the safety and tolerability of bethanechol in combination with gemcitabine and nab-paclitaxel. The exploratory objective will be to evaluate genomic biomarkers associated with parasympathetic stimulation in pancreatic cancer, and the ability to reduce tumor growth rate.

Description

The purpose of this study is to determine whether the drug, bethanechol, could potentially be used in combination with chemotherapy regimen gemcitabine and nab-paclitaxel and surgery to decrease the chance of the cancer coming back after it is removed. Animal models have shown that treatment with bethanechol can inhibit cancer growth and spread. The chemotherapy regimen nab-paclitaxel for use in combination with gemcitabine to treat patients with metastatic pancreatic cancer is FDA approved. Although bethanechol is FDA approved, in this study its use is experimental. The aim of the study is to show that the medication is easy to tolerate and that it shows signs of slowing cancer cell growth. The investigators hypothesize that treatment with bethanechol will alter nerve conduction within tumors by stimulating the parasympathetic nervous system and reduce tumor proliferation, decrease CD44+ expression in cancer cells, decrease tumor growth rate resulting in an improved R0 resection rate.
