• Women \<50 years old would be considered post-menopausal if they have been amenorrhoic for 12 months or more following cessation of exogenous hormonal treatments with luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution
• Women ≥50 years old would be considered post-menopausal if they have been amenorrhoic for 12 months or more following cessation of all exogenous hormonal treatments, radiation-induced oophorectomy with last menses \>1 year ago, chemotherapy-induced menopause with \>1 year interval since last menses, or surgical sterilization (bilateral oophorectomy or hysterectomy)
• Women of childbearing potential (WOCBP) and male patients with partners of childbearing potential must agree to always use a highly effective form of contraception according to the Clinical Trials Facilitation and Coordination Group during the treatment phase of this study and for at least 90 days after the last dose durvalumab or 6 months after the last dose of chemotherapy, whichever occurs last

Exclusion criteria

• Mixed small cell and NSCLC histology
• Neuroendocrine tumor
• Distant metastases
• Malignant pleural effusion or pericardial effusion
• Acute superior vena cava obstruction
• Receipt of prior or current cancer treatment for NSCLC, including but not limited to, surgical resection, radiation therapy, investigational agents, chemotherapy, and monoclonal antibodies (mAbs). Exception: Prior surgical resection of limited metachronous NSCLC (i.e., stage I or II) is permitted.
• Receipt of live attenuated vaccine within 30 days prior to the start of therapy. Note: Patients, if enrolled, should not receive live vaccine during treatment phase and up to 30 days end of treatment
• Major surgical procedure (as defined by the Investigator) within 28 days prior start of treatment.
• Prior exposure to immune-mediated therapy, including but not limited to, other anti-CTLA-4, anti-PD-1, anti-PD-L1 (including durvalumab), and anti-PD-L2 antibodies, including therapeutic anticancer vaccines
• Current use of ongoing long-term immunosuppressive medication. The following are exceptions to this criterion
• Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection)
• Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent
• Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)
• History of allogeneic organ transplantation
• Active or prior documented autoimmune or inflammatory disorders including inflammatory bowel disease \[e.g., colitis or Crohn's disease\], diverticulitis \[with the exception of diverticulosis\], systemic lupus erythematosus, Sarcoidosis syndrome, Wegener syndrome \[granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.\]). The following are exceptions to this criterion:
• Patients with vitiligo or alopecia
• Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement
• Any chronic skin condition that does not require systemic therapy
• Patients without active disease in the last 5 years at randomization may be included but only after consultation with the local study physician
• Patients with celiac disease controlled by diet alone
• Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, ILD, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs, or compromise the ability of the patient to give written informed consent
• Patients with oxygen dependence
• Acute inflammation of mediastinal lymph nodes/mediastinal lymphadenopathy in the context of active pneumoconiosis, sarcoidosis or tuberculosis
• History of another primary malignancy, except for
• Basal cell carcinoma of the skin
• Second malignancy diagnosed \> 2 years prior to NSCLC diagnosis if after curative treatment without persistence or progression at baseline. Patients with a previous history of radiation therapy are eligible provided field overlap is minimal and the risk of toxicity to tissues in the overlapping region(s) is deemed to be acceptable by treating radiation oncologist.
