This phase II trial tests whether hypofractionated intensity modulated radiation therapy with chemotherapy (carboplatin and paclitaxel) and immunotherapy (durvalumab) works to shrink tumors in patients with stage III non-small cell lung cancer. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more cancer cells and have fewer side effects. Chemotherapy drugs, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Durvalumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Giving a higher daily radiation dose delivered over fewer treatments with chemotherapy and immunotherapy may improve shrinkage of tumors and overall survival in patients with non-small cell lung cancer.

PRIMARY OBJECTIVE:
I. To compare locoregional control (freedom from intrathoracic tumor progression) between hypofractionated intensity modulated radiation therapy (IMRT) versus (vs.) standard fractionated radiation therapy (RT).
SECONDARY OBJECTIVES:
I. To compare the acute and late toxicities of hypofractionated vs. standard-fractionated IMRT concurrent with carboplatin and paclitaxel.
II. To compare progression free survival between hypofractionated IMRT vs. standard fractionated RT.
III. To compare overall survival from time of diagnosis to time of death between hypofractionated IMRT vs. standard RT.
IV. To compare the effect of the treatment regimen on the subject’s quality of quality of life before, during and after treatment. (Quality of Life)
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients undergo standard fractionated RT once daily (QD) for 5 days per week (Monday through Friday) and receive paclitaxel intravenously (IV) over 1 hour and carboplatin IV over 30 minutes once weekly (QIW) for 6 weeks in the absence of disease progression or unacceptable toxicity. After radiation therapy, patients receive durvalumab IV every 4 weeks for 12 months in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) scan, positron emission tomography (PET) scan and blood sample collection throughout the study.
ARM II: Patients undergo hypofractionated IMRT QD for 5 days per week (Monday through Friday) and receive paclitaxel IV over 1 hour and carboplatin IV over 30 minutes QIW for 5 weeks in the absence of disease or unacceptable toxicity. After radiation therapy, patients receive durvalumab IV every 4 weeks for 12 months in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan, PET scan and blood sample collection throughout the study.
After completion of study treatment, patients are followed every 6 months for 5 years.
