Testing the Safety of Adding Either Monalizumab (IPH2201) or Oleclumab (MEDI9447) to Durvalumab (MEDI4736) Plus Standard Radiation Therapy for Locally Advanced Non-small Cell Lung Cancer (NSCLC), ARCHON-1 Trial

Inclusion Criteria

• Pathologic (cytological or histological) proof of diagnosis of stage II-III (American Joint Committee on Cancer [AJCC] 8th edition [ed.]) unresectable or inoperable, non-metastatic non-small cell lung cancer (NSCLC) within 60 days prior to registration, with no liver or renal end organ damage, as determined by normal laboratory values noted below. Locally recurrent, N1-N3 disease following surgery without prior radiation therapy is eligible. Patients with N1 to N3 and undetectable primary lung tumors (T0) are eligible
• Pathological diagnosis of PD-L1 high expressing tumors (>= 50%) within 60 days prior to registration (using Dako 22C3 immunohistochemistry [IHC] antibody or the Ventana SP263 antibody platforms) performed at a Clinical Laboratory Improvement Act (CLIA)-certified lab
• Appropriate stage for study entry based on the following diagnostic workup:
• History/physical examination within 30 days prior to registration;
• Positron emission tomography (PET)/computed tomography (CT) scan for staging within 30 days prior to registration (note: if CT portion of PET/CT scan is not of diagnostic quality, then a separate CT scan with contrast is required);
• Magnetic resonance imaging (MRI) scan of the brain with contrast; if medically contraindicated, then CT scan of the brain with contrast (unless medically contraindicated) is acceptable, within 30 days prior to registration;
• Sufficient lung function with forced expiratory volume in 1 second (FEV1) >= 0.8 liter or >= 35% predicted and carbon monoxide diffusing capability (DLCO) >= 40% with or without bronchodilator within 30 days prior to registration;
• Patients who meet the criterion above without oxygen (O2), but who need acute (started within 10 days prior to registration) supplemental oxygen due to tumor-caused obstruction/hypoxia are eligible, provided the amount of the O2 needed has been stable
• Age ≥ 18
• Minimum body weight >= 40 kg
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-2 within 30 days prior to registration
• Absolute neutrophil count (ANC) >= 1500 cells/mm^3 (within 30 days prior to registration)
• Lymphocyte count >= 500 cells/mm^3 (within 30 days prior to registration)
• Platelet count >= 100, 000 cells/mm^3 (within 30 days prior to registration)
• Hemoglobin >= 9.0 g/dL (within 30 days prior to registration) (Note: The use of transfusion or other intervention to achieve hemoglobin [Hgb] >= 9.0 g/dl is acceptable)
• Creatinine clearance >= 40 mL/min by the Cockcroft-Gault (C-G) equation
• Total bilirubin = = 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses > 1 year ago, had chemotherapy-induced menopause with last menses > 1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy)
• Patients who are human immunodeficiency virus (HIV) positive may participate IF they meet the following eligibility requirements:
• They must be stable on their anti-retroviral regimen, and they must be healthy from an HIV perspective
• They must have a CD4 count of greater than 250 cells/mcL
• They must not be receiving prophylactic therapy for an opportunistic infection
• The patient or a legally authorized representative must provide study-specific informed consent prior to study entry

Exclusion Criteria

• Definitive clinical or radiologic evidence of metastatic disease
• Prior invasive malignancy (except those with a negligible risk of metastasis or death and with expected curative outcome [such as adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, localized prostate cancer treated surgically with curative intent, or ductal carcinoma in situ treated surgically with curative intent] or undergoing active surveillance per standard-of-care management [e.g., chronic lymphocytic
