    Time frame: Baseline, safety follow-up (up to 42 months)

    EORTC QLQ-C30 was a 30-question tool used to assess the overall quality of life (QoL) in cancer participants. It consisted of 15 domains: 1 global health status (GHS) scale, 5 functional scales (Physical, role, cognitive, emotional, social), and 9 symptom scales/items (Fatigue, nausea and vomiting, pain, dyspnea, sleep disturbance, appetite loss, constipation, diarrhea, financial impact). The EORTC QLQ-C30 GHS/QoL score ranged from 0 to 100; High score indicated better GHS/QoL. Score 0 represents: very poor physical condition and QoL. Score 100 represents: excellent overall physical condition and QoL.

  39. Combined Therapy (Tepotinib + Osimertinib): Change From Baseline in Health-Related Quality of Life as Assessed by Non-Small Cell Lung Cancer Symptom Assessment Questionnaire (NSCLC-SAQ) at Safety Follow-up (42 Months)

    Time frame: Baseline, safety follow-up (up to 42 months)

    NSCLC-SAQ was a question tool used to assess the overall quality of life (QoL) in cancer participants. It consisted of 5 domains: cough, pain, dyspnea, fatigue, and appetite. The NSCLC-SAQ score ranged from 0 to 20; High score indicated more severe NSCLC-related symptomatology. mains: cough, pain, dyspnea, fatigue, and appetite.

  40. Combined Therapy (Tepotinib + Osimertinib): Area Under the Plasma Concentration-Time Curve From Time Zero to the Last Sampling Time (AUC0-t) of Tepotinib and Its Metabolites (MSC2571109A, MSC2571107A), Osimertinib and Its Metabolite AZD5104

    Time frame: Predose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 hours after tepotinib and Osimertinib administration at Day 1 of Cycle 1 and Day 15 of Cycle 1 (each Cycle is of 21 days) ]

    Area under the plasma concentration versus time curve from time zero to the last sampling time t at which the concentration was at or above the lower limit of quantification (LLQ). AUC0-t was calculated according to the mixed log-linear trapezoidal rule.

  41. Combined Therapy (Tepotinib + Osimertinib): Maximum Observed Plasma Concentration (Cmax) of Tepotinib and Its Metabolites (MSC2571109A, MSC2571107A), Osimertinib and Its Metabolite AZD5104

    Time frame: Predose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 hours after tepotinib and Osimertinib administration at Day 1 of Cycle 1 and Day 15 of Cycle 1 (each Cycle is of 21 days) ]

    Cmax was obtained directly from the concentration versus time curve.

  42. Combined Therapy (Tepotinib + Osimertinib): Time to Reach Maximum Observed Plasma Concentration (Tmax) of Tepotinib and Its Metabolites (MSC2571109A, MSC2571107A), Osimertinib and Its Metabolite AZD5104

    Time frame: Predose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 hours after tepotinib and Osimertinib administration at Day 1 of Cycle 1 and Day 15 of Cycle 1 (each Cycle is of 21 days) ]

    Tmax was obtained directly from the concentration versus time curve.

  43. Combined Therapy (Tepotinib + Osimertinib): Apparent Total Body Clearance (CL/f) of Tepotinib and Its Metabolites (MSC2571109A, MSC2571107A), Osimertinib and Its Metabolite AZD5104

    Time frame: Predose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 hours after tepotinib and Osimertinib administration at Day 1 of Cycle 1 and Day 15 of Cycle 1 (each Cycle is of 21 days) ]

    CL/f was a measure of the rate at which a drug was metabolized or eliminated by normal biological processes. CL/f was calculated as Dose/AUC0-inf, where AUC0-inf was estimated by determining the total area under the curve of the concentration versus time curve extrapolated to infinity. AUC0-inf was calculated as AUC0-t + Clast pred/Lambda Z, where Clast pred was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration was at or above the lower limit of quantification (LLQ) and Lambda Z was the apparent terminal rate constant determined from the terminal slope of the log-transformed plasma concentration curve.

  44. Combined Therapy (Tepotinib + Osimertinib): Apparent Volume Of Distribution (Vz/F) of of Tepotinib and Its Metabolites (MSC2571109A, MSC2571107A), Osimertinib and Its Metabolite AZD5104

    Time frame: Predose, 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, and 24 hours after tepotinib and Osimertinib administration at Day 1 of Cycle 1 and Day 15 of Cycle 1 (each Cycle is of 21 days) ]

    Vz/f: the distribution of a study drug between plasma and the rest of the body after oral dosing. For single dose Vz/f = Dose/(AUC0-inf*Lambda Z), where AUC0-inf = (AUC0-t + Clast pred/Lambda Z). Clastpred was the calculated plasma concentration at the last sampling time point at which the measured plasma concentration was at or above the LLQ and Lambda Z = the apparent terminal rate constant determined from the terminal slope of the log-transformed plasma concentration curve.

  45. Percentage of Participants With Resistant Mutations of the Epidermal Growth Factor Receptor (EGFR) Gene or Other Pathways as Assessed in Circulating Tumor Deoxyribonucleic Acid (ctDNA)

    Time frame: From Day 1 of Cycle 3 up to end of treatment (14 days after last dose, approximately assessed up to 35.6 months) (each Cycle is for 21 days)

    Percentage of participants with resistant mutations of the EGFR gene or other pathways as assessed in ctDNA were reported.
