RecruitingPhase 2Drug trialA Study of Nuzefatide Pevedotin (BT5528) in Patients With Metastatic Pancreatic Ductal Adenocarcinoma (PDAC)This is a Phase 2 study for nuzefatide pevedotin (BT5528) in adults with a specific type of pancreatic cancer called metastatic pancreatic ductal adenocarcinoma (PDAC) that has spread and worsened after one previous treatment. The drug, nuzefatide pevedotin (nuzefatide), is designed to find a specific protein called EphA2. The main aims of the study are to see how well the drug works against the tumor (efficacy), what side effects it may have (safety), and how the body processes it (pharmacokinetics). All participants in this study will receive nuzefatide, and both they and their doctors will know what is being administered (single-arm, open-label). The trial will take place at several different medical centers.
