On March 1, 2024, the Food and Drug Administration approved amivantamab-vmjw with carboplatin and pemetrexed for the first-line treatment of 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.
The FDA also granted traditional approval to amivantamab-vmjw for adult patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy. FDA previously granted accelerated approval for this indication.
Full prescribing information for amivantamab-vmjw will be posted here.
Efficacy was evaluated in PAPILLON (NCT04538664), a randomized, open-label multicenter trial of 308 patients with EGFR exon 20 insertion mutations. Patients were randomized 1:1 to receive amivantamab-vmjw with carboplatin and pemetrexed or carboplatin and pemetrexed.
The major efficacy outcome measure was progression-free survival (PFS) as assessed by blinded independent central review (BICR), with overall survival (OS) as a key secondary outcome measure. Amivantamab-vmjw plus carboplatin and pemetrexed demonstrated a statistically significant improvement in PFS compared with carboplatin and pemetrexed with a hazard ratio of 0.40 (95% CI: 0.30, 0.53; p-value<0.0001). The median PFS was 11.4 months (95% CI: 9.8, 13.7) and 6.7 months (95% CI: 5.6, 7.3) in the respective arms.
While OS results were immature at the current analysis, with 44% of pre-specified deaths for the final analysis reported, no trend towards a detriment was observed.
The most common adverse reactions (≥20%) were rash, nail toxicity, stomatitis, infusion-related reaction, fatigue, edema, constipation, decreased appetite, nausea, COVID-19, diarrhea, and vomiting.
The recommended amivantamab-vmjw dose is based on body weight. See the prescribing information for specific dosage information.
