Eligibility
Inclusion criteria
Inclusion criteria: - Participant must have newly diagnosed histologically or cytologically confirmed, locally advanced or metastatic non-small cell lung cancer (NSCLC) that is treatment naive and not amenable to curative therapy including surgical resection or chemoradiation - The tumor harbors exon 19 deletions (Exon 19del) or Exon 21 L858R substitution, as detected by an food and drug administration (FDA)-approved or other validated test 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) in accordance with site standard of care - Mandatory submission of unstained tissue from tumor (in a quantity sufficient to allow for central analysis of EGFR mutation status and blood (for circulating tumor deoxyribonucleic acid [ctDNA], digital droplet polymerase chain reaction [ddPCR], and pharmacogenomic analysis) - Any toxicities from prior anticancer therapy must have resolved to common terminology criteria for adverse events (CTCAE) Grade 1 or baseline level - Participant must have at least 1 measurable lesion, according to response evaluation criteria in solid tumors (RECIST) v1.1 that has not been previously irradiated. Measurable lesions should not have been biopsied during screening, but if only 1 non-irradiated measurable lesion exists, it may undergo a diagnostic biopsy and be acceptable as a target lesion, provided the baseline tumor assessment scans are performed at least 14 days after the biopsy
Exclusion criteria
Exclusion criteria: - Participant has received any prior systemic treatment at any time for locally advanced Stage III or metastatic Stage IV disease (adjuvant or neoadjuvant therapy for Stage I or II disease is allowed, if administered more than 12 months prior to the development of locally advanced or metastatic disease) - Participant has an active or past medical history of leptomeningeal disease -Participant with untreated spinal cord compression. A participant that has been definitively treated with surgery or radiation and has a stable neurological status for at least 2 weeks prior to randomization is eligible provided they are off corticosteroid treatment or receiving low-dose corticosteroid treatment less than or equal to (<=) 10 milligrams per day (mg/day) prednisone or equivalent - Participant has an active or past medical history of interstitial lung disease (ILD)/pneumonitis, including drug-induced or radiation ILD/pneumonitis - Participant has known allergy, hypersensitivity, or intolerance to the excipients used in formulation of amivantamab, lazertinib, or osimertinib, or any contraindication to the use of osimertinib - Participant has symptomatic brain metastases. A participant with asymptomatic or previously treated and stable brain metastases may participate in this study
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| efficacy Progression-Free Survival (PFS) According to RECIST v1.1 by Blinded Independent Central Review (BICR) Up to approximately 42 months PFS is defined as the time from randomization until the date of objective disease progression or death, whichever occured first, based on BICR using response evaluation criteria in solid tumors (RECIST) v1.1. | — |
Secondary
| Measure | Time frame |
|---|---|
| efficacy Overall Survival (OS) Up to approximately 60 months (time from the date of randomization until the date of death due to any cause) Overall Survival is defined as the time from the date of randomization to the date of participant's death due to any cause. efficacy Objective Response Rate (ORR) Up to approximately 42 months ORR is defined as the percentage of participants who achieve either a complete response (CR) or partial response (PR) as defined by BICR using RECIST v1.1 criteria efficacy Duration of Response (DOR) Up to approximately 42 months DOR is defined as the time from the date of first documented response (CR or PR) until the date of documented progression or death, whichever comes first, only for participants who achieve CR or PR as determined by the investigator using RECIST v1.1 criteria. efficacy Progression-Free Survival After First Subsequent Therapy (PFS2) Up to approximately 42 months The PFS2 is defined as the time from randomization until the date of second objective disease progression, after initiation of subsequent anticancer therapy, based on investigator assessment (after that used for PFS) or death, whichever comes first. efficacy Time to Symptomatic Progression (TTSP) Up to approximately 42 months TTSP is defined as the time from randomization to documentation in the electronic case report form (eCRF) of any of the following (whichever occurs earlier): onset of new symptoms or symptom worsening that is considered by the investigator to be related to lung cancer and requires either a change in anticancer treatment and/or clinical intervention to manage symptoms. efficacy Intracranial PFS Up to approximately 42 months Intracranial PFS is defined as the time from randomization until the date of objective intracranial disease progression or death, whichever comes first, based on BICR using RECIST v1.1. safety Incidence and Severity of Adverse Events (AEs) Up to approximately 60 months Incidence and severity of treatment em | — |
