About

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.
