treatment period and for at least 120 days (corresponding to time needed to
eliminate any study treatments) after the last dose of study treatment.
9. Have provided archival tumor tissue sample or newly obtained core or excisional biopsy
of the tumor lesion.
Note: Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides.

Note: If submitting unstained cut slides, newly cut slides should be submitted to the
testing laboratory within 14 days from the date slides are cut.
10. Have adequately controlled blood pressure (BP) with or without antihypertensive
medications, defined as BP =150/90 mm Hg at Screening and no change in
antihypertensive medications within 1 week before the first dose of study treatment.

an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g.,
CTLA-4, OX 40, CD137) in the last 6 months (6 months are calculated from the last dose
until study initiation).
6. Has received prior systemic anti-cancer therapy mAb, chemotherapy or targeted small
molecule therapy within 4 weeks prior to the planned first dose of the study,
including investigational agents within 4 weeks. For tyrosine kinase inhibitors (TKIs)
and hormonal therapy a shorter interval of 5 half-lives is allowed between prior
therapy and study treatment initiation.
Note: Participants must have recovered from all AEs due to previous therapies to
=Grade 1 or baseline. Participants with =Grade 2 neuropathy may be eligible.
Note: If the participant received major surgery, they must have recovered adequately
from the toxicity and/or complications from the intervention prior to starting study
treatment. Do not administer lenvatinib for at least 2 weeks following major surgery
and until adequate wound healing.
7. Has received prior radiotherapy within 2 weeks of start of study treatment.
Participants must have recovered from all radiation-related toxicities, and not have
had radiation pneumonitis.

non-infectious pneumonitis.
9. Has a history of active tumor bleeding one month before study enrollment.
10. Has received a live vaccine within 30 days prior to the first dose of study drug.
Examples of live vaccines include, but are not limited to, the following: measles,
mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus
Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection
are generally killed virus vaccines and are allowed; however, intranasal influenza
vaccines (e.g., FluMist®) are live attenuated vaccines and are not allowed. Note: mRNA
vaccination for SARS-CoV-2 is not an exclusion.
11. Is currently participating in or has participated in a study of an investigational
agent or has used an investigational device within 4 weeks prior to the first dose of
study treatment. (Note: subjects who participated in local TTF study #0412-08 [A
prospective, multi-center trial of NovoTTF-100A together with temozolomide (TMZ)
compared to TMZ alone in patients with newly diagnosed glioblastoma (GBM)] and are in
follow-up may be eligible for the current study). Note: Participants who have entered
the follow-up phase of an investigational study may participate as long as it has been
4 weeks after the last dose of the previous investigational agent.
12. Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy
(in dosing exceeding 2 mg daily dexamethasone equivalent) or any other form of
immunosuppressive therapy within 7 days prior to the first dose of study drug.
Note: The use of physiologic doses of corticosteroids is allowed.
13. Has a known active second/additional malignancy that is progressing or has required
active treatment within the past 5 years Note: Exceptions include basal cell carcinoma
of the skin, squamous cell carcinoma of the skin, or carcinoma in situ or carcinoma in
situ (e.g. breast carcinoma, cervical cancer in situ) that have undergone potentially
curative therapy.
14. Has severe hypersensitivity (=Grade 3) to pembrolizumab and/or lenvatinib and/or any
of their excipients.
15. Has an active autoimmune disease that has required systemic treatment in the past 2
years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive
drugs).
Note: Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid
replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a
form of systemic treatment.
16. Has an active infection requiring systemic therapy.
17. Has a history of (non-infectious) pneumonitis that required steroids or current
pneumonitis.
18. Has a known history of human immunodeficiency virus (HIV 1/2 antibodies).
19. Has a known history of hepatitis B (defined as hepatitis B surface antigen [HBsAg]
reactive) or known active hepatitis C virus (defined as detected qualitative HCV RNA)
infection.
Note: no testing for hepatitis B and hepatitis C is required unless a known history of
infectious hepatitis is reported.
20. The participant has a known history of active Bacillus Tuberculosis (TB).
21. Has a history or current evidence of any condition, therapy, or laboratory abnormality
that might confound the results of the study, interfere with the subject's
participation for the full duration of the study, or is not in the best interest of
the subject to participate, in the opinion of the treating investigator.
22. Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial.
23. Has had an active allogenic tissue/solid organ transplant.
24. Has uncontrolled blood pressure (Systolic BP>150 mmHg or diastolic BP>90 mmHg) despite
an optimized regimen of antihypertensive medication during 7 days prior to starting
study treatment, or the participant has adequately-controlled blood pressure but has
had a change in antihypertensive medications within 7 days before the first dose of
study treatment.
25. Has clinically significant electrolyte abnormalities that have not been corrected.
26. Has significant cardiovascular impairment: history of congestive heart failure greater
than New York Heart Association (NYHA) Class II, unstable angina, myocardial
infarction (MI) or cerebrovascular accident (CVA) within 6 months of the first dose of
study drug, or cardiac arrhythmia associated with hemodynamic instability requiring
medical treatment at Screening.
27. Has bleeding or thrombotic disorders, radiographic evidence of major blood vessel
invasion/infiltration, or is at risk for severe hemorrhage.
Note: The degree of tumor invasion/infiltration of major blood vessels (e.g. carotid
artery) should be considered because of the potential risk of severe hemorrhage
associated with tumor shrinkage/necrosis following lenvatinib therapy.
28. Has >1+ proteinuria on urine dipstick testing unless a 24-hour urine collection for
quantitative assessment indicates that the urine protein is <1 g/24 hours.
29. Has prolongation of QTc interval to >480 ms.
