Prothrombin time and activated partial thromboplastin time ≤1.5×ULN *Hepatitis* A locally performed hepatitis B (HBV) test is required during screening. Patients who are HBV surface antigen positive are eligible if they have received HBV anti-viral therapy for at least 4 weeks and have undetectable HBV viral load before study entry (ICF signature). Patients should remain on anti-viral therapy throughout study treatment and follow local guidelines for HBV anti-viral therapy post completion of study treatments. A locally performed hepatitis C (HCV) test is required during screening. Patients with history of HCV infection are eligible if HCV viral load is undetectable at screening.

Patients with previously treated brain metastases may participate provided they are radiologically stable, i.e., without evidence of progression for at least 4 weeks confirmed during screening.

Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment and is allowed. Has an active infection requiring systemic therapy Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the study, interfere with the patient's participation for the full duration of the study, or is not in the best interest of the patient to participate, in the opinion of the treating investigator Has a known psychiatric or substance abuse disorder that would interfere with the patient's ability to cooperate with the requirements of the study History of hypersensitivity to any component of cetuximab or to compounds of similar biological or chemical composition of nanrilkefusp alfa and/or the excipients contained in the study drug formulations
