Phase II Trial of Lenvatinib-Pembrolizumab Maintenance Therapy in Patients With Advanced Unresectable Pancreatic Cancer

Trial ID: NCT04887805

Interventional - Phase 2 - Active, not recruiting

This phase II trial studies the effects of lenvatinib and pembrolizumab maintenance therapy in treating patients with pancreatic cancer that has spread to other places in the body (advanced) and cannot be removed by surgery (unresectable). Lenvatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving lenvatinib and pembrolizumab may be effective as a maintenance therapy in patients with pancreatic cancer.
