Janssen Lung Cancer Therapy Approved
FDA has approved a Janssen Pharmaceutical NDA for Rybrevant (amivantamab-vmjw) for treating adult patients with non-small cell lung cancer whose tumors have specific types of genetic mutations — epidermal growth factor receptor (EGFR) exon 20 insertion mutations. The agency also approved Guardant Health’s Guardant360 CDx as a companion diagnostic for determining patient eligibility for the therapy.
Approval was based on data from 81 patients with non-small cell lung cancer and EGFR exon 20 insertion mutations whose disease had progressed on or after platinum-based chemotherapy. “In the trial population in which all patients received Rybrevant, the overall response rate was 40%,” an FDA release says. “The median duration of response was 11.1 months, with 63% of patients having a duration of response of six months or more.”
