What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Part 1: Maximum Observed Plasma Concentration (Cmax) of Lazertinib | Cmax is defined as maximum observed plasma concentration of lazertinib. | Pre dose up to 168 hours post dose on Day 1 | 
| Part 2: Maximum Observed Plasma Concentration (Cmax) of Lazertinib | Cmax is defined as maximum observed plasma concentration of lazertinib. | Pre dose up to 168 hours post dose on Day 1 | 
| Part 1: Area Under the Plasma Concentration-time Curve from Time 0 to 72 Hours (h) (AUC[0-72h]) of Lazertinib | AUC(0-72h) is the area under the plasma concentration-time curve from time 0 to 72 hours. | Pre dose up to 72 hours post dose on Day 1 | 
| Part 2: Area Under the Plasma Concentration-time Curve from Time 0 to 72h (AUC[0-72h]) of Lazertinib | AUC(0-72h) is the area under the plasma concentration-time curve from time 0 to 72 hours. | Pre dose up to 72 hours post dose on Day 1 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Adverse Events (AEs) | An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non-investigational) product. An AE does not necessarily have a causal relationship with the intervention. | Up to 8 Weeks | 
| Number of Participants With Serious Adverse Events (SAEs) | A SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. | Up to 8 Weeks | 
| Number of Participants With AEs by Severity | An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non-investigational) product. Number of participants with AEs by severity will be reported. Severity will be graded according to the National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Severity scale ranges from grade 1 to 5, where Grade 1= mild, Grade 2= moderate, Grade 3= severe, Grade 4= life-threatening and Grade 5= death related to adverse event. | Up to 8 Weeks | 
| Number of Participants With Change From Baseline in Clinical Laboratory Test Values | Number of participants with change from baseline in clinical laboratory test values (including hematology and serum chemistry) will be reported. | Up to 8 Weeks | 
| Number of Participants With Change From Baseline in 12-lead Electrocardiograms (ECGs) | Number of participants with change from baseline in 12-lead ECGs will be reported. | Up to 8 Weeks | 
| Number of Participants With Change From Baseline in Vital Signs | Number of participants with change from baselines in vital signs (including temperature [oral], pulse rate, and blood pressure) will be reported. | Up to 8 Weeks | 
| Number of Participants With Change From Baseline in Physical Examination | Number of participants with change from baseline in physical examination (including height and body weight) will be reported. | Up to 8 Weeks |
