Evaluation of efficacy and safety of pembrolizumab in combination with lenvatinib in patients with recurrent, persistent, metastatic or locally advanced vulva cancer.
Full description
A multicenter, single-arm phase II, open-label study, to evaluate the efficacy and safety of pembrolizumab 400 mg Q6W in combination with lenvatinib 20 mg QD in patients with recurrent, persistent, metastatic or locally advanced VSCC not amenable to salvage surgery or definitive (chemo)radiation.

Inclusion criteria
Signed written informed consent obtained prior to initiation of any study-specific procedures and treatment as confirmation of the patients awareness and willingness to comply with the study requirements.
Female patients who are at least 18 years of age on the day signing informed consent
Histologically confirmed locally advanced, recurrent, persistent and/or metastatic VSCC not amenable for salvage surgery or definitive (chemo)radiation (additive palliative radiotherapy for symptom control is allowed)
≤2 previous lines of chemotherapy for recurrent or metastatic disease
Measurable disease (investigator assessed RECIST 1.1). Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
Have an eastern cooperative oncology group (ECOG) performance status of 0-1. Evaluation of ECOG is to be performed within 7 days prior to the first dose of study intervention.
No pregnancy (as documented by a positive beta-human chorionic gonadotropin [ß-hCG] or human chorionic gonadotropin [hCG]) test with a minimum sensitivity of 25 IU/L or equivalent units of ß-hCG [or hCG]), no breastfeeding, and at least one of the following conditions applies:
A WOCBP should not become pregnant during the treatment and for at least four months.
Available archival tumor tissue sample and/or newly obtained core or excisional biopsy of a tumor lesion ideally not previously irradiated. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides.
Adequate organ function as defined in Table 3 of study protocol. Specimens must be collected within 10 days prior to the start of study treatment.
Exclusion criteria
Non squamous cell histology
Contraindications regarding treatment with pembrolizumab:
allergy or hypersensitivity to pembrolizumab or one of the components.
Contraindications regarding treatment with lenvatinib: allergy or hypersensitivity to lenvatinib or one of the components or:
Bradyarrhythmia
Arterial dissection/aneurysm
Long QT Syndrome
Significant cardiovascular impairment: history of congestive heart failure greater than New York Heart Association (NYHA) Class II, unstable angina, myocardial infarction or stroke within 12 months of the first dose of study drug, or cardiac arrhythmia requiring medical treatment at screening.
History or evidence of major thrombotic (e.g. symptomatic pulmonary embolism) or hemorrhagic disorders within 6 months prior to day 1, cycle 1. The degree of tumor invasion/infiltration of major blood vessels (e.g. carotid artery) should be considered because of the potential risk of severe haemorrhage associated with tumor shrinkage/necrosis following lenvatinib therapy.
Allogenic tissue/solid organ transplant.
Diagnosis of immunodeficiency
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). 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 and is allowed.
History of a second malignancy, unless potentially curative treatment has been completed with no evidence of malignancy for 2 years (time requirement does not apply for definitively treated early endometrial cancer (FIGO IA/B), in-situ carcinomas [e.g. breast, cervix, bladder], or basal or squamous cell carcinoma of the skin).
Gastrointestinal malabsorption, gastrointestinal anastomosis, or any other condition that might affect the absorption of lenvatinib.
Active CNS metastases and/or carcinomatous meningitis. Patients with previously treated brain metastases may participate provided they are radiologically stable, i.e. without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study intervention.
History of (non-infectious) pneumonitis/interstitial lung disease that required steroids or has current pneumonitis/interstitial lung disease.
Active infection requiring systematic therapy.
Has active hemoptysis within 3 weeks prior to the first dose of study intervention or tumor bleeding within 2 weeks prior randomization.
Known history of Human Immunodeficiency Virus (HIV) infection
History of Hepatitis B (defined as Hepatitis B surface antigen [HBsAg] reactive) or known active Hepatitis C virus (defined as HCV RNA [qualitative] is detected) infection.
Known history of active TB (Bacillus tuberculosis).
Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
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.
Pregnancy
Breastfeeding Prior/ Concomitant Therapy
Prior therapy with 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).
Systemic use of corticosteroids or immunosuppressive drugs within 7 days prior start of study treatment (see EC 11.)
Note: Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster, yellow fever, rabies, BCG, and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed as other killed vaccines, if done at least 2 weeks prior the first dose of study drug; however, intranasal influenza vaccines (e.g. FluMist®) are live attenuated vaccines and are not allowed.
Antiarrhythmics of classes Ia and III and other QT-interval prolongation drugs
Prior systemic anti-cancer therapy including investigational agents within 4 weeks [could consider shorter interval for kinase inhibitors or other short half-life drugs] prior to allocation.
Prior radiotherapy within 2 weeks of start of study intervention. Patients must have recovered from 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-CNS disease.
Not recovered adequately from any toxicity from other anticancer 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.
Administration of a live, attenuated vaccine within 30 days prior first dose of study drug. Diagnostic Assessments
Uncontrolled blood pressure (Systolic BP >140 mmHg or diastolic BP >90 mmHg) in spite of an optimized regimen of antihypertensive medication.
Change of anti-HTN (hypertension) medical regimen within 1 week prior to randomization
Prolongation of corrected QT interval (QTc interval) >480 ms
Left ventricular ejection fraction (LVEF) below the institutional normal range as determined by multigated acquisition scan (MUGA) or echocardiogram (ECHO).
Electrolyte abnormalities that have not been corrected.
Subjects having >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. Prior/Concurrent Study Experience
Prior enrolment on a clinical study evaluating pembrolizumab and lenvatinib for a carcinoma, regardless of treatment received.
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 intervention. Note: Patients 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.
