NMPA approves LungCure CDx, a NGS-based companion diagnostic, to guide sunvozertinib use in EGFR exon 20 insertion mutation–positive NSCLC. This marks the first NMPA approval of a co-developed NGS-based companion diagnostic in China. LungCure CDx detects EGFR, MET, ERBB2, KRAS, BRAF, PIK3CA, ALK, ROS1, and RET mutations in NSCLC, aiding targeted therapy selection. Sunvozertinib received NMPA approval for advanced NSCLC with EGFR exon 20 insertion mutations, supported by phase 2 WO-KONH6 trial results. The drug also holds FDA breakthrough therapy designations for relapsed/refractory and frontline NSCLC with EGFR exon 20 insertion mutations.
