What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 520 participants in total. It began in 2022-11-11 with a primary completion date of 2027-08-17.

Brief Summary

The purpose of this study is to assess the anti-tumor activity and safety of amivantamab which will be administered as a co-formulation with recombinant human hyaluronidase PH20 (rHuPH20) (subcutaneous co-formulation \[SC-CF\]) in combination treatment (all cohorts except Cohort 4) and to characterize the safety of amivantamab SC-CF (Cohort 4).

Eligibility Criteria

Inclusion Criteria: * Participant must have histologically or cytologically confirmed, locally advanced or metastatic, non-small cell lung cancer (NSCLC) that is not amenable to curative therapy including surgical resection or chemoradiation. Additional Cohort specific disease requirements include: Cohorts 1, 3, 3b, 5, 6 and 7: epidermal growth factor receptor (EGFR) exon 19 deletion (Exon19del) or Exon 21 L858R mutation; Cohort 2: EGFR Exon 20ins mutation. Cohorts 1,5,and6: Participant should not have received any prior systemic therapy for locally advanced or metastatic NSCLC. Cohort 2: Participant should not have received any prior systemic therapy for locally advanced or metastatic NSCLC. Cohorts 3and3b: Participant must have progressed on or after osimertinib monotherapy as the most recent line of treatment. Osimertinib must have been administered as either the first-line treatment for locally advanced or metastatic disease or in the second-line setting after prior treatment with first- or second-generation EGFR tyrosine kinase inhibitor (TKI) as a monotherapy. Cohort 4: Participants need to currently be on an amivantamab IV Q2W regimen (1,050 mg or 1,400 mg depending on weight) for at least 8 weeks, as part of standard of care, an expanded access program, or as a rollover from a long-term extension, without any amivantamab dose reduction. Cohort 7: Participants must have progressed on or after the combination of amivantamab and lazertinib as the most recent line of treatment. The combination of amivantamab and lazertinib must have been administered as the first-line treatment for locally advanced or metastatic disease. Cohort 2, 3, 3b, and 7 only: Squamous NSCLC are excluded. EGFR mutation 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 * All cohorts except Cohort 4: Participants must 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 If only 1 non-irradiated measurable lesion exists, which undergoes a biopsy and is acceptable as a target lesion, the baseline tumor assessment scans should be performed at least 14 days after the biopsy * 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 * Cohort 6: Must be eligible for, and agree to comply with, the use of prophylactic anticoagulation with a direct oral anticoagulant or a low molecular weight heparin during the first 4 months of study treatment * A 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. Participants with child bearing potential 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 * For all cohorts (with 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) All cohorts: 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) All cohorts (with regimens potentially including lazertinib): Participant has a significant genetic predisposition to venous thromboembolic events (VTE; such as Factor V Leiden); c) All cohorts (with regimens potentially including lazertinib): Participant has a prior history of VTE and is not on appropriate therapeutic anticoagulation as per NCCN or local guidelines; d) 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); e) uncontrolled (persistent) hypertension: systolic blood pressure \>160 millimeter(s) of mercury (mmHg); diastolic blood pressure \>100 mmHg; f) 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); g) pericarditis/clinically significant pericardial effusion; h) myocarditis; i) 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
