Experimental: Part D: Outside of Korea
Participants from outside of Korea with progressive disease and on prior epidermal growth factor receptor (EGFR) Tyrosine kinase inhibitor (TKI) therapy will receive recommended phase 2 doses based on safety, tolerability, efficacy and pharmacokinetics (PK) of Lazertinib.

Drug: Lazertinib
Participants will receive Lazertinib tablets once daily.

- Part D: Number of Participants with Adverse Event as a Measure of Safety and Tolerability [ Time Frame: Up to 2 years ]An adverse event is any untoward medical event that occurs in a participants administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.
- Part D: Plasma Concentration of Lazertinib After Administration of Single Dose (SD) [ Time Frame: Up to 2 years ]Plasma Concentration of Lazertinib after administration of single dose will be evaluated.
- Part D: Plasma Concentration of Lazertinib After Administration of Multiple Dose (MD) [ Time Frame: Up to 2 years ]Plasma Concentration of Lazertinib after administration of multiple dose will be evaluated.
- Part D: Plasma Concentration of Lazertinib Metabolites (M6 and M7) After Administration of Single and Multiple Dose [ Time Frame: Up to 2 years ]Plasma Concentration of Lazertinib metabolites (M6 and M7) after administration of single and multiple dose will be evaluated.
- Part D: Overall Response Rate (ORR) [ Time Frame: Up to 2 years ]ORR is defined as the percentage of participants who have at least one confirmed Partial response (PR) or Complete response (CR) (according to Response Evaluation Criteria in Solid Tumors [RECIST] 1.1) prior to disease progression or recurrence. CR is defined when all target lesions (TLs) and non-target lesions (NTLs) present at baseline have disappeared (with the exception of lymph nodes which must be less than (<)10 millimeters (mm) to be considered non-pathological) and no new lesions have developed since baseline. PR is defined when the sum of diameters of the TLs has decreased by 30 percent (%) or more compared to baseline (with no evidence of progression) and the NTLs are at least stable with no evidence of new lesions.
- Part D: Duration of Response (DoR) [ Time Frame: Up to 2 years ]DoR is defined as the time from the date of first documented responses until date of documented progression or death whichever comes first.
- Part D: Disease Control Rate (DCR) [ Time Frame: Up to 2 years ]DCR is defined as the percentage of participants with a best overall, extracranial and intracranial response of CR, PR or Stable Disease (SD). CR is defined as disappearance of all target lesions since baseline. Any pathological lymph nodes selected as target lesions must have a reduction in short axis to < 10 mm. PR is defined as At least a 30% decrease in the sum of the diameters of TL, taking as reference the baseline sum of diameters. SD is defined as Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm for extracranial and intracranial lesion, respectively.
- Part D: Tumor Shrinkage [ Time Frame: Up to 2 years ]Tumor shrinkage is measured at each visit by the percentage change in the sum of the diameters of target lesions compared to baseline measured as greater than or equal to (>=) 10 mm in the longest lesion diameter with computed tomography (CT) or magnetic resonance imaging (MRI).
- Part D: Progression Free Survival (PFS) [ Time Frame: Up to 2 years ]PFS is defined as the time from first dosing date until documented disease progression or death from any cause whichever occur first based on investigator assessment using RECIST 1.1. PD is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm for extracranial and intracranial lesion, respectively.
- Part D: Overall Survival (OS) [ Time Frame: Up to 2 years ]OS is defined as the interval between the date of first dose and the date of participants death due to any cause.

- Male participants who have not undergone a vasectomy must agree to use barrier contraception that is, condoms, and refrain from donating sperm until 3 months after last drug is taken
- During the study, and for 3 months after receiving the last dose of study drug, female participants must agree not to donate eggs (ova, oocytes) and male participants must agree not to donate sperm for the purposes of assisted reproduction
- In Part D: Participants outside Korea with histologically or cytologically (that is, using pleural effusion, ascites) confirmed Non-Small Cell Lung Cancer (NSCLC) with previously diagnosed epidermal growth factor receptor single activating mutation positive (EGFRm+), and who have had progressive disease on prior epidermal growth factor receptor- Tyrosine kinase inhibitor (EGFR-TKI) therapy
- Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1 with no deterioration over the previous 2 weeks and a minimum life expectancy of 3 months
Exclusion Criteria:
- An unapproved investigational product from another clinical study within 30 days of the first dose of study treatment
- Treatment with an EGFR TKIs (example: erlotinib or gefitinib) within 8 days or approximately 5x half-life, whichever is the longer, of the first dose of study treatment or other investigational products within approved indication of marketed product (if sufficient wash-out time has not occurred due to schedule or PK properties, an alternative appropriate wash-out time based on known duration of time to reversibility of drug related adverse events could be agreed upon by sponsor and the Investigator)
- Any cytotoxic chemotherapy or other anticancer drugs for the treatment of advanced NSCLC from a previous treatment regimen within 14 days of the first dose of study treatment
