In brief

This early phase I trial studies the effect of pembrolizumab and lenvatinib in treating patients with gastroesophageal adenocarcinoma that has spread to other places in the body (advanced/metastatic) or cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Lenvatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and lenvatinib may kill more tumor cells.

• Male and female subjects who are at least 18 years of age on day of signing informed consent with histologically and cytologically documented diagnosis as gastric or gastroesophageal adenocarcinoma
• Has a documented, previously treated, advanced (unresectable and/or metastatic) gastroesophageal adenocarcinoma that is incurable and for which prior first-line or later-line standard of care (SOC) treatments have failed. Prior neoadjuvant or adjuvant therapy included in initial treatment may not be considered first- or later-line SOC treatment unless such treatments were completed less than 12 months prior to the current tumor recurrence
• Has submitted an evaluable tissue sample for biomarker analysis from a newly obtained irradiated. The tumor tissue submitted for analysis must be from a single tumor tissue specimen and of sufficient quantity and quality to allow biomarker study (see laboratory manual). A "newly obtained" tumor specimen, defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on day 1, for biomarker characterization will be required for enrollment of all subjects. Tissue from tumor progressing at a site of prior radiation (at least 6 weeks interval after last radiation) may be allowed for biomarker characterization upon agreement from Merck. Subjects for whom newly-obtained samples cannot be provided (e.g., inaccessible or subject safety concern) may submit an archived specimen only upon agreement from the Merck
• Has measurable disease based on RECIST 1.1 as assessed by the Investigator. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions

• Creatinine clearance should be calculated per institutional standard
• Total bilirubin < 1.5 x ULN OR direct bilirubin =< ULN for subjects with total bilirubin levels > 1.5 x ULN (specimens must be collected within 5 days prior to the start of study treatment)
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]) =< 2.5 x ULN OR =< 5 x ULN for subjects with liver metastases (specimens must be collected within 5 days prior to the start of study treatment)
• Albumin >= 2.5 mg/dL (specimens must be collected within 5 days prior to the start of study treatment)
• International normalized ratio (INR) or prothrombin time (PT) activated partial thromboplastin time (aPTT) =< 1.5 x ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants (specimens must be collected within 5 days prior to the start of study treatment)
• Male subjects are eligible to participate if they agree to the following during the intervention period and for at least 30 days after the last dose of lenvatinib
• 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
• 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 women of child birth potential (WOCBP) who is not currently pregnant. Note: Men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal intercourse or use a male condom during each episode of penile-vaginal penetration.
• Please note that 30 days after lenvatinib is stopped, if the subject is on pembrolizumab only, no male contraception measures are needed
• A female subject is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies:
• Is not a WOCBP OR
• Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of < 1% per year) and has a low user dependency, or is abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis), as described in Appendix 12.8 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 (i.e., noncompliance, recently initiated) in relationship to the first dose of study intervention

You may not qualify if…

• Is currently participating in or has participated in a study of an investigational agent or used an investigational device within 4 weeks prior to the first dose of study treatment.
• Note: Subjects who have entered the follow-up phase of an investigational trial may participate as long as it has been 4 weeks after the last dose of the previous investigational agent
• Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment

• Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are radiological 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 the first dose of trial treatment. This exception does not include carcinomatous meningitis which is excluded regardless of clinical stability
• 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). 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
