A Study of Narmafotinib Given in Combination With Modified FOLFIRINOX in Patients With Metastatic Pancreatic Cancer

This study is testing narmafotinib, a type of drug called a focal adhesion kinase (FAK) inhibitor, when it is given in combination with 4 chemotherapy drugs in a regimen called FOLFIRINOX, to patients who have pancreatic cancer which has metastasised (spread). The study is being run in 2 parts. Part A will test increasing dose levels of narmafotinib in at least 3 people per dose at up to 4 dose levels to assess safety. Part B will test 2 of the dose levels from Part A in 20 people per dose, to select the best dose to take forward into future studies. Participants will take narmafotinib as oral capsules every day. They will also receive mFOLFIRINOX chemotherapy on Day 1 and and Day 15 of 28-day cycles.
