About

This study tests regorafenib as a single agent in the treatment of metastatic pancreatic cancer patients who have progressed after prior chemotherapy with gemcitabine. The prognosis for these patients is particularly grim, no other standard treatment options exist, and novel approaches are desperately needed.

Full description

This is a single arm, single stage Phase II study designed to evaluate progression free survival (PFS) in patients with metastatic pancreatic cancer who have failed at least one prior line of therapy and treatment with gemcitabine. This study is open at the Levine Cancer Institute (LCI). A total of 32 patients will be enrolled over a two years. Following informed consent and eligibility check, all patients will start oral regorafenib therapy (120 mg daily for 3 weeks on / 1 week off; 28 day cycle) with a built-in dose escalation to 160mg after the first cycle as tolerated, and will continue therapy until progression or patient withdrawal. Patients will undergo radiological staging after the first two cycles of regorafenib therapy. Patients with progressive disease will be removed from the study. Patients who have at least stable disease will continue regorafenib therapy, at the Investigator's discretion, and will be radiologically restaged bimonthly.
