Study Summary

GTI-4419-203 will be an open-label, multi-center study to evaluate GC4419 (avasopasem manganese) administered intravenous (IV) for the reduction of radiation induced esophagitis in subjects receiving chemoradiotherapy for unresectable Stage 3A/3B or post-operative Stage 2B Non-Small Cell Lung Cancer (NSCLC) or Small Cell Lung Cancer (SCLC) treatable with chemoradiotherapy.

Primary Outcome

Those subjects in the primary efficacy population that experience acute radiation esophagitis (Grade \>/=2; NCI CTCAE version 5) through the end of chemoradiotherapy for NSCLC or SCLC when treated with avasopasem. NCI CTCAE Grading: Grade 1: asymptomatic; clinical or diagnostic observations only; intervention not indicated Grade 2: symptomatic; altered eating/swallowing; oral supplements indicated Grade 3: severely altered eating/swallowing; tube feeding, total parental nutrition (TPN) or hosp
