About

The efficacy and safety of the use of pembrolizumab in combination with lenvatinib.

Full description

In this study, if combination therapy with lenvatinib and pembrolizumab in patients with gastric cancer is judged to be effective, a prospective treatment regimen can be expected for a larger number of participating subjects.

The anticipated disadvantages include any adverse events associated with lenvatinib and pembrolizumab. To minimize the risk and disadvantages of adverse events, the data center together with the Data and Safety Monitoring Committee will monitor any adverse events in the present trial to determine whether or not they are within the expected range. These bodies will also conduct a thorough examination in the event that serious or unexpected adverse events occur, and adopt an appropriate system to take any necessary actions.
