Use of High Dose Radiation Followed by Chemotherapy and Radiation to Treat Locally Advanced NSCLC

This study's primary objective is to assess the efficacy of a treatment regimen involving Stereotactic Body Radiation Therapy (SBRT) delivered to the primary tumor followed by concurrent mediastinal chemoradiation by evaluating the proportion of subjects with locally-advanced non-small cell lung cancer (NSCLC) stage II/III who are alive and progression free at 12 months, and to compare to relevant historical controls. Additionally, the treatment regimen will be evaluated based on progression free survival, overall survival, radiologic clinical complete response rate following completion of therapy, objective response rate as defined by RECIST v 1.1, local and locoregional control, patterns of failure, and quality of life. Safety objectives include the rate of grade 2+ radiation pneumonitis and grade 3+ pulmonary events. Exploratory objectives include differential expression of cytokines and chemokines associated with radiation therapy will be determined.
