- Event-Free Survival (EFS) [ Time Frame: Randomization to disease recurrence/progression or death from any cause (estimated as up to 7 years) ]EFS by Investigator Assessment in the Primary Analysis Population
- EFS [ Time Frame: Randomization to disease recurrence/progression or death from any cause (estimated as up to 7 years) ]EFS by investigator assessment in the overall population
- Overall Survival (OS) [ Time Frame: Randomization to death from any cause (estimated as up to 9 years)] ]OS
- EFS [ Time Frame: Randomization to disease recurrence/progression or death from any cause (estimated as up to 7 years)] ]EFS by blinded independent central review (BICR)
- Time to Distant Disease Recurrence in the Central Nervous System (CNS) [ Time Frame: Randomization to disease recurrence/progression or death from any cause (estimated as up to 7 years) ]Time to distant disease recurrence in the CNS by investigator assessment and BICR
- Progression Free Survival on the Next Line of Treatment (PFS2) [ Time Frame: Randomization to disease progression on the next line of treatment or death from any cause (estimated as up to 9 years) ]PFS2 by investigator assessment
- Positive Predictive Value (PPV) of Local Lab Tests Compared to Central Lab Test to Detect Rearranged during Transfection (RET) Gene Fusion [ Time Frame: Baseline ]PPV of local lab tests compared to central lab test to detect RET gene fusion
- Mean Change from Baseline over Time in NSCLC Symptoms [ Time Frame: Baseline to treatment discontinuation (estimated as up to 3 years) ]NSCLC symptoms will be measured using the 7-item NSCLC Symptom Assessment Questionnaire (NSCLC-SAQ). The NSCLC-SAQ measures the severity/frequency of the following core symptoms: Cough, pain, dyspnea, fatigue, and appetite. Raw scores range from 0 to 4 and the total score ranges from 0-20. Higher scores represent worse symptoms.
- Mean Change from Baseline over Time in Physical Function [ Time Frame: Baseline to treatment discontinuation (estimated as up to 3 years) ]Physical function will be measured by the 5 physical function items in the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30) (also known as the EORTC IL 19 questionnaire). Raw scores range from 0-20. Higher scores indicate worst function.
