Inclusion criteria
Inclusion criteria: 1. Have a histologically or cytologically-documented, advanced metastatic and/or unresectable) solid tumor that is incurable and for which prior standard systemic therapy has failed in one of the following cohorts: Cohort A Triple-Negative Breast Cancer (TNBC) Cohort B Ovarian Cancer Cohort C Gastric Cancer Cohort D Colorectal Cancer Cohort E Glioblastoma (GBM) Cohort F Biliary Tract Cancer (BTC) (intrahepatic, extrahepatic cholangiocarcinoma and gall bladder cancer; excludes Ampulla of Vater) Cohort G Pancreatic Cancer (ductal adenocarcinoma) 2. Participants must have fulfilled cohort-specific requirements regarding prior (line of therapy) treatments. 3. Participants must have progressed on or since the last treatment. 4. Have measurable disease per RECIST 1.1 (RANO for the GBM cohort) as assessed by the local site investigator/radiology and confirmed by BICR. Lesions situated in a previously irradiated area are considered measurable if progression has been shown in such lesions. 5. Have provided a PD-L1 evaluable archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides. Newly obtained biopsies are preferred to archived tissue. Fine-needle aspiration biopsies are not acceptable. 6. Participants are at least 18 years of age; male or female for gastric cancer, GBM, TNBC, CRC, BTC, and pancreatic cancer cohorts; female only for ovarian cancer. 7. Life expectancy of 12 weeks or more. 8. Male participants are eligible to participate if they agree to the following during the intervention period and for at least 7 days after the last dose of lenvatinib: a. Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent OR b. Must agree to use contraception unless confirmed to be azoospermic (vasectomized or secondary to medical cause) as detailed below: - Agree to use a male condom plus partner use of an additional contraceptive method when having penile-vaginal intercourse with a WOCBP who is not currently pregnant. - 7 days after lenvatinib is stopped, if the participant is on pembrolizumab only, no male contraception measures are needed. 9. A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least 1 of the following conditions applies: - Is not a woman of childbearing potential (WOCBP) OR - Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1% per year), with low user dependency, or be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis), during the intervention period and for at least 120 days post pembrolizumab or 30 days post lenvatinib, whichever occurs last. The investigator should evaluate the potential for contraceptive method failure (ie, noncompliance, recently initiated) in relationship to the first dose of study intervention - A WOCBP must have a negative highly sensitive pregnancy test (urine or serum as required by local regulations) within 24 hours before the first dose of study intervention. - If a urine test cannot be confirmed as negative (eg, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive. 10. The participant (o

Has pre-existing =Grade 3 gastrointestinal (GI) or nongastrointestinal fistula. 12. 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 coinhibitory T-cell receptor (eg, CTLA-4, OX-40, CD137). 13. Has received prior systemic anticancer therapy including investigational agents within 4 weeks before study treatment start. 14. Has not recovered adequately from the toxicity and/or complications from the intervention if participant received major surgical intervention before starting study treatment. 15. Has received prior radiotherapy within 2 weeks of start of study treatment. 16. Has received a live vaccine within 30 days before the first dose of study intervention. 17. Has known intolerance to lenvatinib (and/or any of the excipients). 18. Has participated or is currently participating in a study of an investigational agent or has used an investigational device within 4 weeks before the first dose of study intervention. 19. Has urine protein =1 g/24h. Participants with proteinuria >1+ on urine dipstick testing will undergo 24-hour urine collection for quantitative assessment of proteinuria. 20. Has prolongation of QTc interval (calculated using Fridericia's formula) to >480 ms. 21. Has left ventricular ejection fraction (LVEF) <55% as determined by multigated acquisition scan (MUGA) or echocardiogram (ECHO). 22. 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 intervention. 23. Has known active CNS metastases and/or carcinomatous meningitis. 24. Has tumors involving the brain stem. 25. Has severe hypersensitivity (=Grade 3) to pembrolizumab and/or any of its excipients. 26.

| Main Objective: 1. To evaluate objective response rate (ORR) of pembrolizumab (MK-3475) in combination with lenvatinib (MK-7902) per tumor cohort based on Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST 1.1) by investigator assessments in initial cohorts and blinded independent central review (BICR) in cohorts that expand combining the initial and expansion cohorts (Cohorts A-F). In Cohort G, RECIST 1.1 by BICR will be utilized in all participants (for participants with glioblastoma [GBM], response will be assessed based on Response Assessment in Neuro-Oncology [RANO] criteria) 2. To assess safety and tolerability of treatment with pembrolizumab in combination with lenvatinib per tumor cohort assessed by the percentage of adverse events (AEs) 3.

To evaluate disease control rate (DCR), duration of response (DOR) and progression-free survival (PFS) of pembrolizumab in combination with lenvatinib per tumor cohort based on RECIST 1.1 (RANO for GBM) by investigator assessments in initial cohorts and BICR in cohorts that expand combining the initial and expansion cohorts (Cohorts A-F).
