Editorial: Global Regulatory Initiatives Deliver Accelerated Approval of the First Bispecific Therapeutic Monoclonal Antibody for Advanced Non-Small Cell Lung Cancer (NSCLC).

The coronavirus disease 2019 (COVID-19) pandemic has affected the number of completed clinical trials, particularly in oncology. Between 80-85% of all lung cancers are non-small cell lung cancer (NSCLC), and of these, between 2-3% have an EGFR exon 20 insertion, which is associated with increased cell proliferation, metastasis, and a lack of response to chemotherapy and epidermal growth factor receptor (EGFR) inhibitors. Until this year, there were no available targeted therapies for advanced NSCLC with this genetic subtype. However, in May 2021, the US Food and Drug Administration (FDA) granted accelerated approval for amivantamab-vmjw (Rybrevant®), a bispecific monoclonal antibody, targeting activating and resistant EGFR and MET mutations and amplifications. This FDA approval was for adult patients with locally advanced metastatic NSCLC, with disease progression on or following platinum-based chemotherapy. The FDA also approved the Guardant360® companion diagnostic, a next-generation sequencing platform for circulating tumor DNA (ctDNA), which is a liquid biopsy assay. In 2019, Project Orbis was launched by the FDA Oncology Center of Excellence as a global collaborative review program to facilitate rapid global access for patients to innovative cancer therapies. This Editorial aims to highlight how global regulatory initiatives from the FDA have delivered accelerated approval of the first bispecific therapeutic monoclonal antibody, amivantamab-vmjw (Rybrevant®), and a companion diagnostic for patients with advanced NSCLC with an EGFR exon 20 insertion.
