Eligibility Criteria
-----------------
Inclusion Criteria: Must be healthy on the basis of medical history performed at screening and physical examination and vital signs (pulse rate and body temperature) performed at screening and admission to the study site Participants must be healthy on the basis of clinical laboratory tests performed at screening. If the results of the serum chemistry or hematology panel are outside the normal reference ranges, the participant may be included only if the investigator judges the abnormalities or deviations from normal to be not clinically significant. This determination must be recorded in the participant's source documents and initialed by the investigator Body mass index (BMI) between 18.0 and 30.0 kilogram per meter square (kg/m^2, inclusive (BMI = weight/height^2), and body weight not less than 50 kg at screening Blood pressure at screening and admission to the study site (after the participant supine for 5 minutes) between 90 and 140 millimeter of Mercury (mmHg) systolic, inclusive; and no higher than 90 mmHg diastolic at screening A 12-lead electrocardiogram (ECG) consistent with normal cardiac conduction and function, including: Sinus rhythm, Pulse rate between 45 and 100 beats per minute (bpm), corrected QT (QTc) interval less than or equal to (<=) 450 millisecond (msec), QRS interval of less than (<)120 msec, PR interval <210 msec Exclusion Criteria: History of infection suspected or confirmed to be related to Coronavirus disease 2019 (COVID-19) within 4 weeks before intake of study drug Participant has known allergies, hypersensitivity, or intolerance to lazertinib or any of its excipients Participant has a positive test for hepatitis A antibody immunoglobulin M (IgM), hepatitis B surface antigen (HBsAg), hepatitis B (anti-HBc or anti-HBs), or hepatitis C (anti-HCV) antibodies positive at screening. Hepatitis B surface antibody positivity is not exclusionary if participant can provide evidence of Hepatitis B vaccination Participant who plans to father a child while enrolled in the study or within 6 months after study drug administration Exposure to radiation for professional or medical reasons with the exception of up to 2 standard diagnostic radiographs (example, [dental X-rays, plain chest X-ray]) within 1 year before study drug administration on Study Day 1. Participants cannot have participated in a radiolabeled drug study within 12 months prior to dosing if the dose was higher than 0.1 megabecquerel (MBq)

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Observed Plasma Concentration (Cmax) of 14C-lazertinib | Cmax is defined as maximum observed plasma concentration. | Up to 99 days | 
| Time to Reach Maximum Observed Plasma Concentration (Tmax) of 14C-lazertinib | Tmax is defined time to reach the maximum observed concentration. | Up to 99 days | 
| Area Under the Plasma Concentration-time Curve from Time Zero to Time of Last Quantifiable Concentration (AUC [0-last]) of 14C-lazertinib | AUC (0-last) is defined as area under the plasma concentration-time curve from time 0 to the time of last observed quantifiable concentration. | Up to 99 days | 
| Area Under the Plasma Concentration-time Curve from Time Zero to Infinity (AUC [0-infinity]) of 14C-lazertinib | AUC (0-infinity) is defined as area under the plasma concentration-time curve from time 0 to infinity, calculated as the sum of AUC(0-last)+C(last)/ lambda(z), where C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant. | Up to 99 days | 
| Elimination Half-life (t1/2) of 14C-lazertinib | Elimination half-life associated with the terminal slope lambda(z) of the semilogarithmic drug concentration-time curve, calculated as 0.693/lambda(z). | Up to 99 days | 
| Apparent Terminal Elimination Rate Constant (Lambda[z]) | Lambda(z) is defined as apparent terminal elimination rate constant, estimated by linear regression using the terminal log-linear phase of the log transformed concentration vs time data. | Up to 99 days | 
| Total Apparent Clearance (CL/F) of 14C-lazertinib | Clearance is a quantitative measure of the rate at which a drug substance is removed from the body, calculated as dose/AUC (0-infinity). | Up to 99 days |
