Summary
Brief summary (as posted)
This phase I trial studies the side effects and best dose of bosentan and how well it works when given together with gemcitabine and nab-paclitaxel for the treatment of pancreatic cancer that cannot be removed by surgery (unresectable). Bosentan may block the hormone endothelin and prevent the growth and spread of pancreatic cancer. Drugs used in chemotherapy, such as gemcitabine and nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving bosentan with chemotherapy (gemcitabine and nab-paclitaxel) may work better in treating patients with pancreatic cancer compared to chemotherapy alone.
