LEAP-005: This Phase II trial is trying to determine how safe and effective a combination therapy (with pembrolizumab and lenvatinib) is in treating patients with select advanced cancersA Multicenter, Open-label Phase 2 Study of Lenvatinib (E7080/MK-7902) Plus Pembrolizumab (MK-3475) in Previously Treated Subjects With Selected Solid Tumors

Exclusion

• Has radiographic evidence of encasement or invasion of a major blood vessel or of intratumoral cavitation. Participants with portal vein invasion (Vp4), inferior vena cava, or cardiac involvement based on imaging in the BTC cohort are not eligible for enrollment
• Has clinical significant hemoptysis or tumor bleeding within 2 weeks prior to the first dose of study treatment
• Has significant cardiovascular impairment within 12 months of the first dose of study treatment, such as history of congestive heart failure greater than New York Heart Association (NYHA) Class II, unstable angina, myocardial infarction or cerebrovascular accident (CVA), or cardiac arrhythmia associated with hemodynamic instability
• Has a history of arterial thromboembolism within 12 months of start of study treatment
• Has a known additional malignancy that is progressing or has required active treatment within the past 3 years.
• Has a serious nonhealing wound, ulcer or bone fracture
• Has had major surgery within 3 weeks prior to first dose of study interventions
• Has biologic response modifiers therapy (e.g. granulocyte colony-stimulating factor) within 4 weeks before study entry
• Has preexisting ≥Grade 3 gastrointestinal (GI) or non-gastrointestinal fistula
• Has received prior therapy with lenvatinib, an anti-PD-1, anti-PD-L1, or anti PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g. cytotoxic T-lymphocyte-associated protein 4 [CTLA-4], Tumor necrosis factor receptor superfamily, member 4 [OX 40], tumor necrosis factor receptor superfamily member 9 [CD137])
• Has received prior systemic anti-cancer therapy including investigational agents within 4 weeks prior to study treatment start
• If participant received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment
• Has received prior radiotherapy within 2 weeks of start of study treatment. Participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis. A 1-week washout is permitted for palliative radiation (≤2 weeks of radiotherapy) to non-central nervous system (CNS) disease
• Has received a live vaccine within 30 days prior to the first dose of study treatment
• Has known intolerance to lenvatinib (and/or any of the excipients)
• 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
• Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior the first dose of study treatment
• Has known active CNS metastases and/or carcinomatous meningitis
• Has tumors involving the brain stem
• Has severe hypersensitivity (≥Grade 3) to pembrolizumab and/or any of its excipients
• Has an active autoimmune disease that has required systemic treatment in past 2 years
• Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis
• Has an active infection requiring systemic therapy
• Has a known history of human immunodeficiency virus (HIV) infection
• Has a known history of hepatitis B or known active hepatitis C virus infection
• Has a known history of active tuberculosis (TB; Bacillus tuberculosis)
• Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of study treatment
• Has had an allogenic tissue/solid organ transplant (large organ transplants, stem-cell transplant requiring chronic immunosuppressant therapy necessary to prevent graft rejection)

For GBM Participants:

• Has carcinomatous meningitis
• Has recurrent tumor greater than 6 cm in maximum diameter
• Has tumor primarily localized to the brainstem or spinal cord
• Has presence of multifocal tumor, diffuse leptomeningeal or extracranial disease
• Has evidence of intratumoral or peritumoral hemorrhage on baseline magnetic resonance imaging (MRI) scan other than those that are grade ≤ 1 and either post-operative or stable on at least 2 consecutive MRI scans
• Has received Optune® TTFields within 2 weeks of study intervention
