ABSTRACT

Many targeted therapies to treat genetic mutations in non–small cell lung cancer (NSCLC) have been developed. Amivantamab
(Rybrevant), a bispecific antibody targeting the epidermal growth factor receptor (EGFR) and mesenchymal-epithelial transition factor, was approved by the US Food and Drug Administration in 2021 for the treatment of adult patients with locally advanced or metastatic NSCLC EGFR exon 20 insertions, whose disease progressed on or after platinum-based chemotherapy. Amivantamab is administered intravenously weekly for 4 weeks, then every 2 weeks starting at Week 5, as 1,050 mg (body weight [BW]
< 80 kg) or 1,400 mg (BW 80 kg), with the first dose split over 2 days. Infusion-related reactions (IRRs) are common with amivantamab and may present as chills, dyspnea, nausea, chest discomfort, and vomiting. To aid in the prevention, diagnosis, and treatment of IRRs, we evaluated infusion duration, IRR timing, and IRR severity in this post hoc analysis of patients who received amivantamab in CHRYSALIS. Infusion duration decreased over time, with a median infusion time at Cycle 1 Day 1 (C1D1) of 4.70 hours (1,050 mg) and 5.08 hours (1,400 mg), decreasing to 2.20 and 2.25 hours, respectively, by C1D22. Of the 273 IRRs, 98% occurred on C1D1 or C1D2, with median onset and time to resolution of 60 minutes. Most IRRs occurred during the infusion, were low grade, and were manageable with intervention strategies or treatment modifications. Advanced practitioners are critical in preventing, diagnosing, and managing IRRs, including educating patients and families, accurately administering infusions, prescribing premedications, and closely monitoring for IRRs.
