His scoring was six based on the Naranjo adverse drug reaction probability scale, indicating a probable drug reaction to amivantamab.Īmivantamab (30% Relative Risk) is safer and controllable compared with poziotinib, and only mild keratosis appeared on the face in amivantamab-treated BA/F3-bearing NOG mice models. In subsequent recurrences, the pus culture and sensitivity did not reveal any pathogens and each time, the skin lesions responded to recombinant human epidermal growth factor gel, compound polymyxin b ointment and kangfuxin liquid. He received 22 more injections of amivantamab, and the rash appeared basically similar to the initial manifestation after about a week of each infusion. He was treated with kangfuxin liquid, compound polymyxin b ointment, compound neomycin ointment and recombinant human epidermal growth factor gel without systemic steroids and continued amivantamab treatment. His haemogram, renal and liver function tests, absolute eosinophil count and peripheral smear analysis were within normal limits. aureus infection, with sensitivity to amoxicillin, gentamicin and tetracycline. The pulse, blood, pressure, respiratory rate, temperature, lymph nodes were normal. ![]() The cutaneous adverse events were grade 3 in severity. Erosive erythema was seen on the perianal area. Dermatological examination showed purulent crusts on the scalp, scattered erythematous papules on the face, legs and scrotum along with scattered crusts on the face. He complained of skin pain but without any accompanying constitutional symptoms like fever, breathlessness, facial oedema, jaundice, etc. He began to develop facial skin lesions that gradually extended to the scalp, buttocks and lower limbs after three weeks of treatment. The dosage of amivantamab was 1050 mg weekly for the first four weeks, and then every two weeks thereafter. ![]() His genetic testing showed epidermal growth factor receptor (EGFR) exon 20 insertion mutations and hence was treated with amivantamab (JNJ61186372)-targeted therapy. 2 We report a case of adverse cutaneous reaction following amivantamab treatment.Ī 53-year-old man without a history of skin disease was diagnosed as right lung adenocarcinoma with multiple mediastinal lymph node metastases. 1 Acting on both targets provides amivantamab an “avidity effect,” which is superior to poziotinib or cetuximab in terms of therapeutic efficacy. Amivantamab is a bispecific monoclonal antibody that targets both EGFR and mesenchymal-epithelial transition factor. This resistance is mediated by multiple mechanisms, which include secondary EGFR mutation and activation of the c-mesenchymal-epithelial transition factor pathway. Activating EGFR mutations render resistance to treatment with EGFR tyrosine kinase inhibitors. The Food and Drug Administration (FDA) granted accelerated approval to amivantamab for adult patients with locally advanced or metastatic non-small cell lung cancer with epidermal growth factor receptor (EGFR) exon 20 insertion mutations, whose disease has progressed on or after platinum-based chemotherapy.
