About
There is no standard second line treatment in malignant pleural mesothelioma (MPM). Pembrolizumab has shown to be active in in small phase II studies in MPM. Its activity however, is limited, with a response rate up to 20%. Since the arrival of nivolumab plus ipilimumab as first line standard of care treatment in mesothelioma, no treatment options are investigated in this group of patients in the second line. So, there is a need for new treatment combinations with drugs that might exhibit a synergistic interaction with pembrolizumab.
Full description
There is no standard second line treatment in malignant pleural mesothelioma (MPM). Pembrolizumab has shown to be active in in small phase II studies in MPM. Its activity however, is limited, with a response rate up to 20%. So, there is a need for new treatment combinations with drugs that might exhibit a synergistic interaction with pembrolizumab. The mechanisms of actions of lenvatinib, which has a broad spectrum of activities, predicts many synergistic interactions with PD-1 blocking. The aim of this study is to characterize the potential clinical activity, toxicity and biomarkers of outcome of pembrolizumab - lenvatinib in patients with recurrent MPM.

Inclusion criteria
Histologically or cytologically diagnosed malignant pleural mesothelioma, age at least 18 years
Progressive disease after at least 1 and maximal 2 prior systemic treatment lines:
Measurable disease. At least one measurable lesion according to Modified RECIST 1.1 for pleural mesothelioma. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions
WHO-ECOG performance status of 0 to 1. Evaluation of ECOG is to be performed within 7 days prior to date of allocation
Adequate organ function
Ability to understand the study and give signed informed consent (or legally acceptable representative if applicable) prior to beginning of protocol specific procedures including the approval of the thoracoscopy or transthoracic pleural biopsy before the first treatment cycle and an optional biopsy before the third treatment cycle
No presence of clinically relevant treatment-related toxicity from previous chemotherapy, targeted therapy and/or radiotherapy. Note: Participates must have recovered from all AEs due to previous therapies to ≤Grade 1 or baseline. Participants with ≤2 neuropathy may be eligible
No active uncontrolled infection, severe cardiac dysfunction (i.e. unstable angina, history of myocardial infarction within the past 12 months prior to screening, congestive heart failure > NYHA II, serious cardiac arrhythmia), unstable peptic ulcer, unstable diabetes mellitus or other seriously disabling condition
Adequately controlled blood pressure (BP) with or without antihypertensive medications, defined as BP ≤150/90 mmHg at screening ad no change in hypertensive medication within 1 week before the cycle 1/day1.
No prior therapy with an anti-PD-1, anti-PD-L1, or anti PD L2 agent or with another agent agents direct to another stimulatory or co-inhibitory T-cell receptor (eg CTLA-4, OC-40, CD137) or TKI or antibody targeting angiogenesis in the first cohort. Patients who have been treated with autologous tumor cell vaccination (eg. Dendritic cell-based immunotherapy) will be eligible in the first cohort. (First cohort is closed).
No concomitant administration to any other experimental drugs under investigation ≤ 4 weeks prior to first admission of pembrolizumab- lenvatinib
No prior radiotherapy within 2 weeks before start of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids as therapy for radiation induced toxicities. A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-CNS disease.
No major injuries and/or surgery within the past 4 weeks prior to first study dose with incomplete wound healing
