Pembrolizumab With and Without Radiotherapy for Non-Small Cell Lung Cancer

Diagnosis/Condition for Entry into the Trial

Histologically or cytologically confirmed non-small cell lung cancer, performed on a biopsy that occurred within the last 60 days.
Positron Emission Tomography (PET)-CT within the last 30 days showing radiographic stage I to IIIa lung cancer (mediastinal staging biopsy is allowed but not required).
Documentation that the patient is a candidate for surgical resection of their lung cancer by an American Board of Thoracic Surgery-certified surgeon.
Measurable disease as defined by RECIST v1.1.
Adequate tissue specimens for correlative biomarker analysis. The patient should be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion. Newly-obtained is defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on Day 1. 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 Principal Investigator.
Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
Resolution of all acute toxic effects of prior chemotherapy, radiotherapy or surgical procedures to NCI CTCAE Version 4.0 grade 1.

Inclusion Criteria:

Be willing and able to provide written informed consent/assent for the trial.
Be at least 18 years of age on day of signing informed consent.

Demonstrate adequate organ function as defined below. All screening labs should be performed within 10 days of treatment initiation.

System Laboratory Value Hematological Absolute neutrophil count (ANC) greater than or equal to 1,500 /microliter (mcL) Platelets greater than or equal to 100,000 / mcL Hemoglobin greater than or equal to 9 g/dL or ≥5.6 mmol/L without transfusion or erythropoietin (EPO) dependency (within 7 days of assessment)

Renal Serum creatinine OR Measured or calculated creatinine clearance (GFR can also be used in place of creatinine or CrCl) less than or equal to 1.5 X upper limit of normal (ULN) OR

Greater than or equal to 60 mL/min for subject with creatinine levels greater than 1.5 X institutional ULN Hepatic Serum total bilirubin Less than or equal to 1.5 X ULN aspartate aminotransferase (AST)/serum glutamic-oxaloacetic transaminase (SGOT), alanine aminotransferase (ALT)/serum glutamic-pyruvic transaminase (SGPT) Less than or equal to 2.5 X ULN

Coagulation International Normalized Ratio (INR) or Prothrombin Time (PT)

Activated Partial Thromboplastin Time (aPTT) Less than or equal to 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 Less than or equal to 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

Creatinine clearance should be calculated per institutional standard.

Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

Female subjects of childbearing potential must be willing to use an adequate method of contraception for the course of the study through 120 days after the last dose of study medication.

Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.

Male subjects of childbearing potential must 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.

Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.

Exclusion Criteria:

Is ineligible for an operation based on medical or oncologic contraindications to surgery.
Has history of non-infectious pneumonitis/interstitial lung disease that required steroids, or has current pneumonitis/interstitial lung disease.
Has evidence of interstitial lung disease.
Has an active second malignancy, i.e. patient known to have potentially fatal cancer present for which he/she may be (but not necessarily) currently receiving treatment. Patients with a history of malignancy that has been completely treated, with no evidence of that cancer currently, are permitted to enroll in the trial if curative therapy has been completed, such as basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.
Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment.
Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment.
Has a known history of active Bacillus Tuberculosis (TB)
Hypersensitivity to pembrolizumab or any of its excipients.
Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or who has not recovered (i.e., Less than or equal to Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.

Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1 or who has not recovered (i.e., less than or equal to Grade 1 or at baseline) from adverse events due to a previously administered agent.

Note: Subjects with less than or equal to Grade 2 neuropathy are an exception to this criterion and may qualify for the study.
Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
Has 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 (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
Has an active infection requiring systemic 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.
Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment.
Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.
Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).
Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (HCV) (e.g., HCV RNA [qualitative] is detected).
Has received a live vaccine or live-attenuated vaccine within 30 days prior to the first dose of the study drug. Administration of killed vaccines is allowed.
