About
This phase II trial studies how well pembrolizumab works in treating patients with epidermal growth factor receptor (EGFR) mutant non-small cell lung cancer that have not received prior tyrosine kinase inhibitor therapy and has spread to other places in the body. Monoclonal antibodies, such as pembrolizumab, may block growth in different ways by targeting certain cells.
Full description
PRIMARY OBJECTIVES:
I. Determine efficacy (objective response rate (ORR)) of front-line pembrolizumab for metastatic EGFR mutation positive programmed cell death 1 ligand 1 (PD-L1)+ (> 1% by immunohistochemistry [IHC]) non-small cell lung cancer (NSCLC).
SECONDARY OBJECTIVES:
I. Determine safety (adverse event tabulation and grading) of front-line pembrolizumab for metastatic EGFR mutation positive PD-L1+ (> 1% by IHC) NSCLC.
II. Determine efficacy (progression free survival (PFS), overall survival (OS)) of front-line pembrolizumab for metastatic EGFR mutation positive PD-L1+ (>1% by IHC) NSCLC.
III. Determine ORR, PFS and OS of subsequent EGFR tyrosine kinase inhibitor (TKI) therapy in patients with EGFR-sensitizing mutation after pembrolizumab.
TERTIARY OBJECTIVE:
I. Analyze tumor tissue biomarkers for potential correlation with response.
OUTLINE:
Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 3 weeks for up to 35 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for up at 3 and 6 months, and then every 9 weeks thereafter.

-
Albumin >= 2.5 mg/dL
-
International Normalized Ratio (INR) or Prothrombin Time (PT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants
-
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
-
Have provided tissue for PD-L1 biomarker analysis from a newly obtained formalin fixed tumor tissue from a biopsy of a tumor lesion not previously irradiated; the tissue sample must be received and evaluated by the study site prior to start of treatment; fine needle aspirates are not acceptable; needle or excisional biopsies, or resected tissue is required
-
Have a PD-L1 positive (either strongly or weakly) tumor as determined by the IHC 22C3 pharmDx test at the study site; if a patient's initial tumor specimen is not classified as PD-L1 positive by the central laboratory, a newly obtained specimen (different from the sample previously submitted) may be submitted for testing; if the newer specimen is classified as PD-L1 positive by the study site, the patient meets this eligibility criterion
-
Have resolution of toxic effect(s) of the most recent prior chemotherapy to grade 1 or less (except alopecia); if subject received major surgery or radiation therapy of > 30 Gy, they must have recovered from the toxicity and/or complications from the intervention
-
Female subject of childbearing potential has a negative urine or serum pregnancy test; if the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required; the serum pregnancy test must be negative for the subject to be eligible
-
Female subjects may be enrolled in the trial if they are:
- of non-childbearing potential which is defined as:
- of childbearing potential who are willing to use either 2 adequate barrier methods or a barrier method plus a hormonal method of contraception to prevent pregnancy, or to abstain from heterosexual activity throughout the trial, starting with the screening visit (visit 1) through 120 days after the last dose of MK-3475 (pembrolizumab)
-
Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy

- Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator
- Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
