Studying Chemotherapy With or Without Panitumumab for Unresectable, Locally Advanced, or Metastatic Pancreatic Cancer Without KRAS Mutations

This phase III trial compares the effect of adding panitumumab to standard chemotherapy (with nanoliposomal Irinotecan, leucovorin, and 5-fluorouracil \[5-FU\] or irinotecan, leucovorin, and 5-FU or nab-paclitaxel and gemcitabine) versus standard chemotherapy alone in treating patients with KRAS wild type (WT) pancreatic ductal adenocarcinoma that cannot be removed by sugery (unresectable) or that has spread to nearby tissue or lymph nodes (locally advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). Panitumumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Chemotherapy drugs, such as nanoliposomal irinotecan, leucovorin, 5-FU, irinotecan, nab-paclitaxel and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Adding panitumumab to standard chemotherapy may be effective in treating patients with unresectable, locally advanced, or metastatic KRAS WT pancreatic ductal adenocarcinoma.
