A Study of Amivantamab in Participants With Advanced or Metastatic Solid Tumors Including Epidermal Growth Factor Receptor (EGFR)-Mutated Non-Small Cell Lung Cancer

Inclusion Criteria:

Participant must have histologically or cytologically confirmed, locally advanced or metastatic, non-small cell lung cancer (NSCLC). Additional Cohort specific disease requirements include: Cohorts 1 and 3: epidermal growth factor receptor (EGFR) exon 19 deletion (Exon19del) or Exon 21 L858R mutation; Cohort 2: EGFR Exon 20ins mutation EGFR Exon19del or Exon 21 L858R mutation (Cohort 1 and 3) or EGFR Exon 20 insertion mutation (Cohort 2) must have been identified as determined by Food and Drug Administration (FDA) approved or other validated test of either circulating tumor deoxyribonucleic acid (ctDNA) or tumor tissue in a clinical laboratory improvement amendments (CLIA) certified laboratory (sites in the United states [US]) or an accredited local laboratory (sites outside of the US). A copy of the initial test report documenting the EGFR mutation must be included in the participant records and a deidentified copy must also be submitted to the sponsor
Have at least 1 measurable lesion, according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. If the only target lesion has been previously irradiated, it must show signs of disease progression since radiation was completed
May have a prior or concurrent second malignancy (other than the disease under study) which natural history or treatment is unlikely to interfere with any study endpoints of safety or the efficacy of the study treatment(s)
Have adequate organ (renal, hepatic, hematological, coagulation and cardiac) functions
Participant must have eastern cooperative oncology group (ECOG) status of 0 or 1
A female participant must agree not to donate eggs (ova, oocytes) or freeze for future use for the purposes of assisted reproduction during the study and for a period of 6 months after receiving the last dose of study treatment. Female participants should consider preservation of eggs prior to study treatment as anti-cancer treatments may impair fertility

Exclusion Criteria:

Participant has a medical history of interstitial lung disease (ILD), including drug induced ILD or radiation pneumonitis
Participant has a history of hypersensitivity to any excipients of the investigational products to be used in their enrollment cohort
Participant has received a live or live attenuated vaccine within 3 months before Cycle 1 Day 1. The seasonal influenza vaccine and non-live vaccines against Coronavirus disease 19 (COVID-19) are not exclusionary
Cohorts 1, 3, and 4 (regimens potentially including lazertinib): Participant is currently receiving medications or herbal supplements known to be potent Cytochrome (CYP3A4/5) inducers and is unable to stop use for an appropriate washout period prior to Cycle 1 Day 1
Other clinically active liver disease of infectious origin
Participant has a history of clinically significant cardiovascular disease including, but not limited to: a. diagnosis of deep vein thrombosis or pulmonary embolism within 1 month prior to the first dose of study treatment(s), or any of the following within 6 months prior to the first dose of study treatment(s): myocardial infarction, unstable angina, stroke, transient ischemic attack, coronary/peripheral artery bypass graft, or any acute coronary syndrome. Clinically non-significant thrombosis, such as non-obstructive catheter-associated clots, are not exclusionary. b. prolonged corrected QT interval by Fridericia (QTcF) interval greater than (>) 480 milliseconds (msec) or clinically significant cardiac arrhythmia or electrophysiologic disease (example, placement of implantable cardioverter defibrillator or atrial fibrillation with uncontrolled rate).c. uncontrolled (persistent) hypertension: systolic blood pressure >160 millimetre(s) of mercury (mmHg); diastolic blood pressure >100 mmHg. d. Congestive heart failure defined as NYHA class III-IV or hospitalization for congestive heart failure (CHF) (any New York Heart Association [NYHA] class) within 6 months of treatment initiation at Cycle 1/day 1 (C1D1). e. pericarditis/clinically significant pericardial effusion. f. myocarditis. g. baseline left ventricular ejection fraction (LVEF) below the institution's lower limit of normal at screening, as assessed by echocardiogram or multigated acquisition (MUGA) scan
Participant has symptomatic brain metastases. A participant with asymptomatic or previously treated and stable brain metastases may participate in this study. Participants who have received definitive radiation or surgical treatment for symptomatic or unstable brain metastases and have been clinically stable and asymptomatic for at least 2 weeks before Screening are eligible, provided they have been either off corticosteroid treatment or are receiving low-dose corticosteroid treatment (less than or equal to [<=] 10 milligrams per day [mg/day] prednisone or equivalent) for at least 2 weeks prior to treatment allocation
