Outcome results

Primary

Number of Subjects With of Acute Radiation Esophagitis (Defined as Grade >/= 2; NCI CTCAE Version 5) Through the End of Chemoradiotherapy for Non-Small Cell Lung (NSCLC) or Small Cell Lung Cancer (SCLC) When Avasopasem Was Added.

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 hospitalization Grade 4: life-threatening consequences; urgent operative intervention indicated Grade 5: death

Time frame: From the first radiation therapy fraction through the end of the study treatment period, which is estimated to be 6 weeks.

Population: Primary Efficacy Population included all subjects who received at lease 1 dose of GC4419 (avasopasem manganese) and either completed their radiation therapy or discontinued their radiation therapy early but were known to have had acute radiation esophagitis.
