Patients may not have a known or confirmed history of pneumonitis Evidence of current pneumonitis Participants with evidence of pneumonitis on scans at screening will be excluded Patients excluded with any prior treatment of pneumonitis requiring corticosteroids. Pneumonitis and history of pneumonitis. History of pneumonitis History and/or confirmed pneumonitis Patient is confirmed to have actively symptomatic pneumonitis Patients with a history of pneumonitis History of pneumonitis History of pneumonitis within the last 5 years History of pneumonitis within the last 5 years History of pneumonitis Prior history of radiation pneumonitis Known prior history of interstitial pneumonitis, including clinically significant radiation pneumonitis (i.e. affecting activities of daily living or requiring therapeutic intervention) History of pneumonitis or active lung infection History of pneumonitis A history of drug-induced pneumonitis or hypersensitivity pneumonitis from prior ALK TKI therapy Pneumonitis within the last 5 years History of or ongoing drug-induced pneumonitis Patients with active pneumonitis TREATMENT SCREENING: Active pneumonitis Active or prior history of pneumonitis that required corticosteroids Has known history of, or any evidence of active, non-infectious pneumonitis; history of radiation pneumonitis is allowed provided that it is not active and no corticosteroids were required for pneumonitis management Patients with active sepsis or pneumonitis Known history or ongoing diagnosis of pneumonitis Patient has documented pneumonitis which is active and requiring treatment History of acute pneumonitis. Presence of active pneumonitis Pneumonitis that requires oral or IV steroids; Current pneumonitis or history of pneumonitis requiring steroids Ongoing drug-induced pneumonitis Have a history or the presence at baseline of pulmonary interstitial disease, drug-related pneumonitis, or radiation pneumonitis. Participant has history of interstitial lung disease (ILD) OR a history of pneumonitis that has required oral or IV steroids. Participants whose pneumonitis was solely as a result of radiation therapy for their NSCLC would not be excluded from the study unless they received oral/IV steroids to manage the pneumonitis. Subjects with pneumonitis or at risk of pneumonitis; History of drug-induced pneumonitis Ongoing drug-induced pneumonitis History of pneumonitis attributed to an EGFR inhibitor; history of radiation pneumonitis is allowed provided steroid administration for pneumonitis was not required Ongoing active pneumonitis Ongoing drug-induced pneumonitis History of pneumonitis within the last 5 years Diagnosis of diffuse radiation pneumonitis History of pneumonitis
