Amivantamab, also known as JNJ-61186372, is an anti-EGFR-MET bispecific antibody, derived from Chinese hamster ovary cells, approved for the treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy. Patients with NSCLC often develop resistance to drugs that target EGFR and MET individually, so amivantamab was developed to attack both targets, reducing the chance of resistance developing. Amivantamab was found to be more effective than the EGFR inhibitor erlotinib or the MET inhibitor crizotinib in vivo. Patients with NSCLC with exon 20 insertion mutations in EGFR do not respond to tyrosine kinase inhibitors, and were generally treated with platinum-based therapy.
 
Amivantamab was granted FDA approval on 21 May 2021, followed by the approval by the EMA on 9 December 2021 12 and Health Canada on 30 March 2022. On December 17, 2025, the U.S. FDA approved the subcutaneous formulation, across all existing and expanded indications of amivantamab, including its use as a first-line, chemotherapy-free combination regimen with lazertinib.
