Why this trial?

As pancreatic cancers in general, also pancreatic ductal adenocarcinoma (PDAC), the most common form of pancreatic cancer, has a very poor prognosis and rising incidence. Only 15 to 20 percent of PDAC tumours that have not metastasized at diagnosis, are deemed resectable. For patients with a resectable tumour, upfront surgery is the standard of care followed by adjuvant chemotherapy which offers the best chance of curation. Nevertheless, the 5-year overall survival of these PDAC patients is approximately 20% and almost 50% relapses within the first year after surgery. Clearly, there is a need to reduce the number of relapses which will improve the overall survival of PDAC patients.

Why this drug?

Research shows that the time period between diagnosis and surgery represents a window of opportunity for therapy aiming at reducing recurrence. Pancreatic disease recurrence appears to be stimulated by perioperative psychological and surgical stress. Psychological stress is mediated by catecholamines (noradrenalin and adrenalin) and beta-adrenergic signalling, while surgical stress is mediated by prostaglandins synthesised by cyclo-oxygenase 2 (COX2) enzymes, which are typically overexpressed in pancreatic tumour cells.

Many studies indicate that the mechanisms of catecholamines and prostaglandins play an important role in the progression of PDAC, PDAC cell invasion and proliferation, and tumour metastasis. Perioperative co-administration of the beta-blocker propranolol and the COX2-inhibitor etodolac in patients with locally advanced or metastatic pancreatic cancer, showed that overall survival increased with 7 months.

Therefore, the perioperative co-administration of propranolol and etodolac may also contribute to reducing recurrence of newly diagnosed resectable PDAC.

Trial design

This is a phase II, randomised, two-armed, double-blinded, single-centre trial of a combination therapy of propranolol and etodolac in 80 patients with resectable cancer of the pancreatic head planned for elective pancreatoduodenectomy.

The primary objective is to study the safety, feasibility and efficacy data of perioperative propranolol and etodolac in these patients. Eligible patients will be randomised between a daily intake of placebo from 10 days before surgery to 14 days after surgery, or daily intake of 2 doses of 400mg etodolac from 10 days before surgery to 14 days after surgery and 2 doses of 20mg propranolol daily during the 10 days before the operation, 2 doses of 40mg propranolol on the day of surgery and one week after, and 2 doses of 20mg propranolol the second week after the operation. The total duration of treatment is 25 days and the follow-up will be 24 months.
