d) the following cardiovascular diseases - history of congestive heart failure (chf) of grade 3 or higher or heart arrhythmia requiring treatment according to the new york heart association classification (nyha) criteria history of unstable angina or myocardial infarction experienced within six months prior to the first administration of clinical trial drugs e) test results of known human immunodeficiency virus (anti-hiv ab) are positive patients with hepatitis b (hbv) surface antigen (hbsag) positive, hepatitis c antibody (anti-hcv) positive, and other clinically active infectious liver disease, e.g. patients with a history of hcv, can be registered if antiviral therapy is completed and subsequently recorded in a document that hcv rna is below the minimum quantitative limit. in the case of hbsag positive, in the case of a negative polymerase chain reaction to hbv dna g) intractable nausea and vomiting, gastrointestinal diseases, patients who cannot be taken orally, and absorption disorders that are deemed to interfere with the absorption of lazertinib \* however, if a colonectomy is performed and does not involve clinically meaningful absorption disorders according to the researcher's judgment, research registration is possible h) a known history of hypersensitivity in clinical trial drugs i) clinically significant chronic infection or major medical or mental illness j) in a case where it is determined based on the researcher's judgment that the patient should not participate in the clinical trial because the patient is unlikely to be able to comply with the clinical trial procedures, restrictions and requirements 3. heart and clinical laboratory test criteria: 1. any of the following heart criteria: based on qtc levels measured by electrocardiogram (ecg) equipment during screening, qt interval (qtc) correction average \> 470 msec as long as the clinical significance of rhythm, conduction, or form on the ecg during the break. for example, full left angle blocking, 3 degree heart blocking, 2 degree heart blocking, pr interval \> 250 msec all factors that increase the risk of qtc extension or arrhythmia, such as heart failure, hypokalemia, congenital qt extension syndrome, combination medication known to extend the qt interval, qt extension syndrome, or family history of unexplained sudden death under the age of 40. 2. inadequate bone marrow reserve or organ function identified by the following experimental figures: anc \<1.0 x 109/l platelet count \<100 x 109/l hemoglobin \<80 g/l * alanine amino transferase (alt) \> 5 x uln * aspartic acid amino transferase (ast) \> 5 x uln total bilirubin \> 3 x uln if the serum level exceeds 1.5 x uln, the estimated cleaning rate measured using the institutional standard method (e.g., the value calculated by the cockcroft \& gault equation) is less than 45ml/min
