Hedgehog Inhibition for Pancreatic Ductal Adenocarcinoma (PDAC) in the Preoperative Setting (HIPPoS) — HIPPoS  

Pancreatic Ductal Adenocarcinoma Clinical Trial

Official title: Proof of Mechanism Study of an Oral Hedgehog Inhibitor (GDC-0449) in Patients With Resectable Pancreatic Ductal Adenocarcinoma in the Pre-operative Window Period

Status Terminated

Clinical Trial Summary

This clinical trial is looking at the effect of a new drug called GDC-0449 in patients with cancer of the pancreas. Laboratory studies have shown that this drug blocks a process in pancreatic cells thought to be involved in cancer development and spread. This process is called the 'Hedgehog signalling pathway'. As yet, it is unclear whether blocking hedgehog signalling will directly affect the tumour cells themselves or the surrounding normal tissue. Understanding this distinction will help improve treatment strategies for pancreatic cancer. Patients will be offered to participate in this research study if they have localised pancreatic cancer that can be removed by surgery. In the period between diagnosis and surgery the investigators do not normally treat patients, however in this trial the investigators will ask patients to take GDC-0449 during the approximately two weeks until the day of surgery. All patients that enter this study will have undergone a diagnostic biopsy of the pancreatic tumour and the investigators will collect a second sample of the tumour at surgery. The main question of this study is whether the investigators can detect a change in hedgehog signalling in the normal tumour surrounding tissue. Furthermore the investigators will look very carefully whether this treatment is safe for patients. All problems before and after surgery will be carefully documented and the investigators have defined strict rules to stop the study if the investigators observe serious problems.
