• History of (noninfectious) pneumonitis that required systemic steroids or current pneumonitis/interstitial lung disease.
• Radiographic evidence of intratumoral caviations, encasement, or invasion of a major blood vessel. Additionally, the degree of proximity to major blood vessels should be considered for exclusion because of the potential risk of severe hemorrhage associated with tumor shrinkage/necrosis after lenvatinib-therapy. (In the chest, major blood vessels include the main pulmonary artery, the left and right pulmonary arteries, the 4 major pulmonary veins, the superior or inferior vena cava, and the aorta).
• Known history of an additional malignancy, except if the participant has undergone potentially curative therapy with no evidence of that disease recurrence for at least 3 years since initiation of that therapy. Note: The time requirement also does not apply to participants who underwent successful definitive resection of basal cell carcinoma of the skin, superficial bladder cancer, squamous cell carcinoma of the skin, in situ cervical cancer, or other in situ cancers.
• 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 allowed.
• Known history of human immunodeficiency virus (HIV) infection. HIV testing is not required unless mandated by the local health authority.
• Known history of Hepatitis B or active Hepatitis C. No testing for Hepatitis B or Hepatitis C is required unless mandated by the local health authority.
• History of a gastrointestinal condition or procedure that in the opinion of the investigator may affect oral drug absorption.
• Known history of active tuberculosis.
• Active infection requiring systemic therapy.
• Has preexisting ≥Grade 3 gastrointestinal or non-gastrointestinal fistula.
• Has preexisting ≥Grade 3 gastrointestinal or non-gastrointestinal fistula

Laborértékek

• A WOCBP who has a positive urine pregnancy test within 24 hours prior to randomization or treatment allocation. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
• Has a prolongation of QTc interval (calculated using Fridericia's formula) of >480 msecl.
• Left ventricular ejection fraction (LVEF) below the institutional (or local laboratory) normal range as determined by multigated acquisition scan (MUGA) or echocardiogram (ECHO).

• Histologically or cytologically confirmed diagnosis of Stage IV (American Joint Committee on Cancer [AJCC], version 8 or current version), nonsquamous NSCLC.
• Confirmation that Epidermal Growth Factor Receptor (EGFR), ALK Receptor Tyrosine Kinase (ALK), or ROS1 Receptor Tyrosine Kinase (ROS1)-directed therapy is not indicated as primary treatment (documentation of absence of tumor-activating EGFR mutations AND absence of ALK and ROS1 gene rearrangements OR presence of a Kirsten Rat Sarcoma (KRAS) gene mutation).
• Have measurable disease based on RECIST 1.1. Note: Lesions that appear measurable, but are situated in a previously irradiated area, can be considered measurable (eligible for selection as target lesions) if they have shown documented growth since the completion of radiation.
• Provided an archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion (not previously irradiated).
• Life expectancy of at least 3 months.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 within 7 days prior to the first dose of study intervention but before randomization.
• Contraceptive use by men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. If the contraception requirements in the local label for any of the study interventions is more stringent than the requirements above, the local label requirements are to be followed.
• Male participants must agree for at least 7 days after the last dose of lenvatinib/matching placebo and up to 180 days after the last dose of chemotherapeutic agents to:
  • Refrain from donating sperm PLUS either:
  • Be abstinence 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 azoopsermic (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 woman of childbearing 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.
  • Note: 7 days after lenvatinib/matching placebo is stopped, if the participant is on pembrolizumab only and is greater than 180 days post chemotherapy, no male contraception measures are needed.
• Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
• Female participant 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

• Adequately controlled blood pressure (BP) with or without antihypertensive medications, defined as BP ≤150/90 mm Hg and no change in antihypertensive medications within 1 week prior to randomization. Note: Participants must not have a history of uncontrolled or poorly-controlled hypertension, defined as >150/90 mm Hg for >4 weeks despite standard medical management.
