A Study to Determine if the Drug, Pyrvinium Pamoate, is Safe and Tolerable in Patients With Pancreatic Cancer

PRIMARY OBJECTIVE: I. To determine the safety and tolerability of pyrvinium pamoate (PP), dosed orally, in patients with pancreatic ductal adenocarcinoma (PDAC) that are surgical candidates. SECONDARY OBJECTIVE: I. Assessment of PP's pharmacokinetic and pharmacodynamic (PK/PD) profile and bioavailability in humans. OUTLINE: This is a dose-escalation study. Patients receive pyrvinium pamoate orally (PO) once daily (QD) for 3 days in the absence of disease progression or unacceptable toxicity. Patients then undergo standard of care surgery. After completion of study treatment, patients are followed up for 30 days and then every week for up to 4 weeks.
