Primary Outcome Measures :
  1. Progression-free Survival (PFS) [ Time Frame: 30 months ]
    Defined as time from randomization until disease progression or death from any cause, whichever occurs first.


Secondary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: 30 Months ]
    Defined as time from date of randomization to date of death due to any cause.

  2. Adverse Events [ Time Frame: 30 Months ]
    Defined as number of patients with treatment emergent AEs

  3. Objective Response Rate (ORR) [ Time Frame: 30 Months ]
    Defined as the percent of patients documented to have a confirmed CR or PR.

  4. Duration of Response (DOR) [ Time Frame: 30 Months ]
    Defined as the time from date of the first documentation of objective tumor response (CR or PR) to the first documentation of either Progression of Disease (PD) or death due to any cause, whichever occurs first.

  5. 1-year Survival Rate [ Time Frame: 30 Months ]
  6. Plasma PK Parameters of MRTX849 (and metabolites, if applicable) [ Time Frame: 30 Months ]
    Blood plasma concentrations

  7. Patient Reported Outcomes (PROs) [ Time Frame: 30 Months ]
    To be assessed by Lung Cancer Symptom Scale (LCSS).

  8. Quality of LIfe Assessment [ Time Frame: 30 Months ]
    To be assessed by European Quality of Life Five Dimensions Questionnaire (EQ-5D-5L).
