The investigator should evaluate the potential for contraceptive method failure (ie, noncompliance, recently initiated) in relationship to the first dose of study intervention 13. 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; Note: 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; 14. Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures. Exclusion Criteria 1. Patients with vulvar melanomas, sarcomas, vulvar Paget's disease, or basal cell carcinoma; 2. Patients diagnosed with early-stage vulvar cancer that, according to the Investigator, can be treated with upfront curative surgery; 3. Patients who have received any systemic anticancer therapy for vulvar cancer, anti-VEGF therapy, or any systemic investigational anticancer agent including radiotherapy (Cohort A and B); patients who have received any further systemic therapy for advanced disease after progression to a first-line platinum-based chemotherapy (Cohort C); 4. Received a live vaccine or live attenuated within 30 days of planned start of study treatment (Cycle 1/Day 1). Note: The killed virus vaccines (ie seasonal influenza vaccines for injection are allowed); 5. Has preexisting ≥Grade 3 gastrointestinal or non-gastrointestinal fistula; 6. Active infection (any infection requiring systemic treatment); 7. Subjects known to be positive for Human Immunodeficiency Virus (HIV); 8. Patients with known active hepatitis (i.e. Hepatitis B or C) * Active hepatitis B virus (HBV) is defined by a known positive HBV surface antigen (HBsAg) result. Patients with a past or resolved HBV infection (defined as the presence of hepatitis B core antibody and absence of HBsAg) are eligible; * Patients positive for hepatitis C virus (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA; 9. Subjects with a diagnosis of immunodeficiency or who are receiving systemic steroid therapy (dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study medications; 10. Active autoimmune disease that has required systemic treatment in past 2 years (ie, with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment; 11. Patients unable to swallow orally administered medication; 12. Patients receiving any systemic chemotherapy or radiotherapy (except for palliative reasons) within 3 weeks prior to study treatment; 13. Major surgery within 3 weeks of starting study treatment and patients must have recovered from any effects of major surgery; 14. Breast feeding women; 15. Known active CNS metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable, (ie, without evidence of progression) for at least 4 weeks by repeat imaging (Note: The repeat imaging should be performed during study Screening.), clinically stable, and without requirement of steroid treatment for at least 14 days before the first dose of study intervention. Note: Participants with known untreated, asymptomatic brain metastases (ie, no neurological symptoms, no requirement for corticosteroids, no or minimal surrounding edema, and no lesion \>1.5 cm) may participate but will require regular imaging of the brain as a site of disease; 16. Other malignancy unless curatively treated with no evidence of disease for ≥5 years except: adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS), Stage 1, grade 1 endometrial carcinoma 17. Prolongation of QTcF interval to ≥480 msec; 18. LVEF below of the institutional (or local laboratory), normal range, as determinated, by MUGA or ECHO; 19.

Subjects who have not recovered adequately from any toxicity from other anti- cancer treatment regimens and/or complications from major surgery prior to starting therapy. Note: Withhold lenvatinib for at least 1 week prior to elective surgery. Do not administer for at least 2 weeks following major surgery and until adequate wound healing; 21. Significant cardiovascular impairment including: history of congestive heart failure greater than New York Heart Association (NYHA) Class II, unstable angina, myocardial infarction, cerebro vascular accident/stroke, within 12 months of the first dose of study drug, or cardiac arrhythmia associated with hemodynamic instability. Medically controlled arrhytmia would be permitted; 22. Bleeding or thrombotic disorders or subjects at risk for severe hemorrhage. Radiographic evidence of tumor invasion/infiltration of major blood vessels (e.g. carotid artery) or intratumoral cavitation. Note: The degree of major blood vessel should be considered because of the potential risk of severe hemorrhage associated with tumor shrinkage/necrosis following lenvatinib therapy; 23. Radiographic evidence of tumor invasion/infiltration of major blood vessels (e.g. carotid artery) or intratumoral cavitation. Note: The degree of major blood vessel should be considered because of the potential risk of severe hemorrhage associated with tumor shrinkage/necrosis following lenvatinib therapy. 24. History of arterial tromboembolism within 12 months of start the study; 25. Active hemoptysis (bright red blood of at least 0.5 teaspoon) within 3 weeks prior to the first dose of study drug; 26.

GI malabsorption or any other condition that might affect the absorption of Lenvatinib; 28. An allogenic tissue/solid organ transplant; 29. History of (noninfectious) pneumonitis/interstizial lung disease (ILD) that require steroids or current pneumonitis/ interstitial lung disease; 30.
