Exclusion criteria

Exclusion Criteria:

  • History of or current clinically significant medical illness including (but not limited to) cardiac arrhythmias or other cardiac disease, hematologic disease, coagulation disorders (including any abnormal bleeding or blood dyscrasias), lipid abnormalities, significant pulmonary disease, including bronchospastic respiratory disease and interstitial lung disease, diabetes mellitus (with the exception of history of gestational diabetes), hepatic insufficiency, inflammation bowel disease/Crohn's disease, thyroid disease, neurologic or psychiatric disease, infection, or any other illness that the investigator considers should exclude the participant or that could interfere with the interpretation of the study results
  • History of stomach or intestinal surgery or resection, including cholecystectomy, that would potentially alter absorption or excretion of orally administered drugs
  • History of malignancy within 5 years before screening
  • Use of any prescription or nonprescription medication (including vitamins and herbal supplements), except for paracetamol, ibuprofen, and stable hormone replacement therapy (in postmenopausal female participants only) within 14 days before the first dose of study intervention is scheduled until completion of the study

What researchers measure

Primary outcomes

  1. Part 1: Maximum Observed Plasma Concentration (Cmax) of Lazertinib

    Cmax is defined as maximum observed plasma concentration of lazertinib.

    Time frame: Pre dose up to 168 hours post dose on Day 1

  2. Part 2: Maximum Observed Plasma Concentration (Cmax) of Lazertinib

    Cmax is defined as maximum observed plasma concentration of lazertinib.

    Time frame: Pre dose up to 168 hours post dose on Day 1

  3. 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.

    Time frame: Pre dose up to 72 hours post dose on Day 1

  4. 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.

    Time frame: Pre dose up to 72 hours post dose on Day 1

Secondary outcomes

  1. 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.

    Time frame: Up to 8 Weeks

  2. 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.

    Time frame: Up to 8 Weeks

  3. 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.

    Time frame: Up to 8 Weeks

  4. 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.

    Time frame: Up to 8 Weeks

  5. 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.

    Time frame: Up to 8 Weeks

  6. 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.

    Time frame: Up to 8 Weeks

  7. 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.

    Time frame: Up to 8 Weeks
