Summary

This study will investigate the efficacy and safety of the combination of pembrolizumab and lenvatinib in PD-L1 positive patients with TKI-resistant EGFR-mutated advanced NSCLC.

Description

Tyrosine Kinase Inhibitors (TKIs) are the standard front-line treatment for patients with EGFR sensitive mutations. Even though patients have a better response rate and longer PFS comparing to chemotherapy, drug resistance have been an inevitable issue associated with these drugs. The standard of subsequent treatment for TKI resistance at present is chemotherapy (platinum doublet chemotherapy), which shows limited benefit with ORR 20-30% and PFS nearly 4 months. Therefore, it is essential to develop the novel therapies.

Immune checkpoint therapy, which is based on negative regulatory mechanisms and targeted enhancement of the anti-tumor immune response, is a novel and important therapeutic strategy for lung cancer, especially for those patients with PD-1/PD-L1 positive advanced NSCLC. VEGF signaling regulates immune suppression by promoting the expansion of suppressive immune cell populations. Therefore, modulation of VEGF-mediated immune suppression could potentially augment the immunotherapeutic activity of immune checkpoint inhibitors. Lenvatinib is a multitargeted TKI with anti-tumor activity via inhibiting VEGFR 1-3, FGFR 1-4 and PDGFR. It modulates the cancer immunity associated with a decrease in the population of immunosuppressive tumor-associated macrophages and an increase in interferon-γ-producing CD8+ T cells. The combination of immune check point inhibitors (PD-1/PD-L1 inhibitors) and lenvatinib could be a promising strategy to improve the immunotherapy outcome in lung cancer patients.

Eligibility

Yes No Not Sure

Inclusion Criteria

Have a histologically or cytologically confirmed stage IV NSCLC by American Joint Committee on Cancer Version 8
Have confirmation with sensitizing EGFR mutations, either DEL19 or L858R
Have undergone failure 1-2 prior EGFR-TKI (Osimertinib exposure required for T790M+)
Have measurable disease based on RECIST 1.1, as determined by the local site
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
Tumor tissue that demonstrates PD-L1 expression in ≥1% of tumor cells (TPS ≥1%) as
assessed by IHC 22C3 pharmDx
Note: Assessment of PD-L1 expression must be made from provided archival tumor tissue sample or newly obtained core or excisional biopsy of a tumor lesion not previously irradiated. (A fine-needle aspirate, frozen sample, plastic embedded sample, cell block, clot, bone, bone marrow, cytologic specimen, or decalcified or formalin-fixed sample that was frozen at any point will not be acceptable for analysis). Formalin-fixed, paraffin-embedded tissue blocks are preferred to slides. Newly obtained biopsies are preferred to archived tissue

Exclusion Criteria

Has known untreated central nervous system 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: repeat imaging should be performed during study screening), clinically stable, and without requirement of steroid treatment for at least 14 days before first dose of study intervention
Has clinically significant hemoptysis (at least 0.5 teaspoon of bright red blood) or tumor bleeding within 2 weeks before the first dose of study intervention
Bleeding or thrombotic disorders or subjects at risk for severe hemorrhage. The degree of tumor invasion/infiltration of major blood vessels should be considered because of the potential risk of severe hemorrhage associated with tumor shrinkage/necrosis after lenvatinib therapy
Has a 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 for no evidence of disease for at least 3 years does not apply to the NSCLC for which a participant is enrolled in the study. 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
Has an active autoimmune disease that has required systemic treatment in the past 2
years (ie, with the 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 and is
allowed
Has had an allogeneic tissue/solid organ transplant
Has a known history of human immunodeficiency virus (HIV) infection; HIV testing is not required unless mandated by the local health authority
Has a history of (noninfectious) pneumonitis that required systemic steroids or current pneumonitis/interstitial lung disease
Has a known history of hepatitis B (defined as hepatitis B surface antigen [HBsAg] reactive or hepatitis B virus [HBV]-DNA detected) or known active hepatitis C virus (HCV, defined as HCV-RNA [qualitative] detected or HCV antibody reactive, if HCV-RNA is not the local SOC) infection
Note: No testing for hepatitis B and hepatitis C is required unless mandated by the local health authority
Has a history of a gastrointestinal condition or procedure that in the opinion of the
investigator may affect oral study drug absorption
Has significant cardiovascular impairment within 12 months of the first dose of study intervention, such as a history of congestive heart failure greater than New York Heart Association Class II, unstable angina, myocardial infarction, cerebrovascular accident (CVA)/stroke, or cardiac arrhythmia associated with hemodynamic instability
Has not recovered adequately from any toxicity and/or complications from major surgery before starting therapy
Has a known history of active tuberculosis (TB)
Has an active infection requiring systemic therapy
Has a known psychiatric or substance abuse disorder that would interfere with the participant's cooperation for the requirements of the study
Previously had a severe hypersensitivity reaction to treatment with an mAb or has a known sensitivity or intolerance to any component of lenvatinib or pembrolizumab
WOCBP who has a positive urine pregnancy test within 72 hours before the first dose of study intervention. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
Note: In the event that 72 hours have elapsed between the screening pregnancy test and the first dose of study intervention, another pregnancy test (urine or serum) must be performed and must be negative for the participant to start receiving study intervention
Is pregnant or breastfeeding or expecting to conceive or father children within the
projected duration of the study, starting with the screening visit through 120
days after the last dose of study intervention
Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (eg, FluMist®) are live attenuated vaccines and are not allowed
