• •Participants with new or progressive brain metastases (active brain metastases) or leptomeningeal disease must not require immediate CNS specific treatment at the time of study registration or anticipated during the first cycle of therapy
• •Participants must not have had prior treatment with cetuximab or another EGFR inhibitor within the last 365 days

• •Leukocytes ≥ 3 x 10\^3/uL (within 14 days prior to registration)
• •Absolute neutrophil count ≥ 1.5 x 10\^3/uL (within 14 days prior to registration)
• •Platelets ≥ 100 x 10\^3/uL (within 14 days prior to registration)
• •Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN) unless history of Gilbert's disease. Participants with history of Gilbert's disease must have total bilirubin ≤ 5 x institutional ULN (within 14 days prior to registration)
• •Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ≤ 3 × institutional ULN with the exception of subjects with documented liver metastases: AST and/or ALT ≤ 5.0 x institutional ULN (within 14 days prior to registration)
• •Participants must have a measured OR calculated creatinine clearance ≥ 30 mL/min using the following Cockcroft-Gault Formula. This specimen must have been drawn and processed within 14 days prior to registration
• •Participants must not have an active or past medical history of interstitial lung disease (ILD)/pneumonitis, including drug-induced or radiation ILD/pneumonitis
• •Participants must not have a history of lung transplantation
• •Participants must not have a history of pulmonary graft versus host disease (GVHD)
• •Participants must have adequate cardiac function. Participants with known history or current symptoms of cardiac disease, must have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, participants must be class 2B or better
• •Participants with a history human immunodeficiency virus (HIV)-infection must be on effective anti-retroviral therapy at registration and have undetectable viral load test on the most recent test results obtained within 6 months prior to registration
• •Participants with a history of chronic hepatitis B virus (HBV) infection must have undetectable HBV viral load while on suppressive therapy on the most recent test results obtained within 6 months prior to registration, if indicated
• •Participants with a history of hepatitis C virus (HCV) infection must have been treated and cured. Participants currently being treated for HCV infection must have undetectable HCV viral load test on the most recent test results obtained within 6 months prior to registration, if indicated
• •Participants must not have an uncontrolled illness, including but not limited to:
• •* Ongoing or active infection (includes infection requiring treatment with antimicrobial therapy \[participants will be required to complete antibiotics 1 week prior to starting study treatment\])
• •* Active bleeding diathesis
• •* Any ophthalmologic condition that is clinically unstable
• •Participants must not have a prior or concurrent malignancy whose natural history or treatment (in the opinion of the treating physician) has the potential to interfere with the safety or efficacy assessment of the investigational regimen
• •Participants must not be pregnant or nursing (nursing includes breast milk fed to an infant by any means, including from the breast, milk expressed by hand, or pumped) due to known toxicities of amivantamab. Individuals who are of reproductive potential must have agreed to use an effective contraceptive method with details provided as a part of the consent process. A person who has had menses at any time in the preceding 12 consecutive months or who has semen likely to contain sperm is considered to be of "reproductive potential." In addition to routine contraceptive methods, "effective contraception" also includes refraining from sexual activity that might result in pregnancy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) including hysterectomy, bilateral oophorectomy, bilateral tubal ligation/occlusion, and vasectomy with testing showing no sperm in the semen. Participants must agree not to donate ova or sperm for the purpose of reproduction during the study and for a minimum of 6 months after receiving the last dose of study treatment. For female participants of childbearing potential, a negative pregnancy test is required within 72 hours prior to registration
• •Participants must be offered the opportunity to participate in specimen banking
