Brief Summary

In this Phase-II study, the investigators will investigate the efficacy and safety of lenvatinib in combination with pembrolizumab and chemotherapy in patients with malignant pleural mesothelioma.

Detailed Description

This is a single-arm, open-label study to evaluate the efficacy and safety of lenvatinib in combination with pembrolizumab and chemotherapy in patients with malignant pleural mesothelioma. The study will consist of a screening phase, a treatment phase, and a follow-up phase. Patients who meet the Inclusion Criteria, do not meet the Exclusion Criteria, and are judged by the investigator to be eligible for this clinical trial will be included. Subjects who meet all of the criteria listed in Criteria for Administration of Investigational Drugs may continue to receive the investigational drug. If a subject receiving investigational drugs meets any of the criteria listed in Discontinuation Criteria of Investigational Drugs, the subject will be evaluated at the end of the treatment phase (at the time of discontinuation) and moved to the post-observation phase.

5. Patients who are judged by the principal investigator or coinvestigator to have one or more measurable lesions as defined in Modified RECIST by CT or MRI imaging within 28 days prior to enrollment. However, if the measurable lesion is a pleural lesion only and there is a history of pleurodesis (patients who underwent pleurodesis within 14 days prior to enrollment or pleurodesis with Picibanil within 28 days prior to enrollment are excluded), only patients whose measurable lesion was confirmed on imaging after pleurodesis are eligible.

7. Male/female participants who are at least 18 years of age on the day of signing informed consent with histologically confirmed diagnosis of malignant pleural mesothelioma will be enrolled in this study.

8. Have adequate organ function as defined in the following table. All clinical laboratory tests in the screening period should be performed within 10 days prior to the start of study intervention.

Exclusion Criteria

1. Patients with concomitant or pre-existing severe hypersensitivity reactions to other drugs, including antibody preparations

2. A women of childbearing potential who has a positive urine pregnancy test within 72 hours prior to trial registration. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

Note: in the event that 72 hours have elapsed between the screening pregnancy test and the first dose of study treatment, another pregnancy test (urine or serum) must be performed and must be negative in order for subject to start receiving study medication.
