TOKYO and XIAMEN, July 23, 2025 - Riken Genesis Co., Ltd., Amoy Diagnostics Co., Ltd. (“AmoyDx”), and Precision Medicine Asia Co., Ltd. (“PREMIA”) today announced that the Japanese Ministry of Health, Labour and Welfare (MHLW) has approved the AmoyDx® Pan Lung Cancer PCR Panel (the “AmoyDx® PLC Panel”) as a companion diagnostic (CDx) for indication of Amivantamab plus Lazertinib combination therapy in Japan.
The combination therapy of Amivantamab and Lazertinib is recommended as a treatment for patients with unresectable advanced or recurrent non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutant tumors. Amivantamab and Lazertinib, marketed by Johnson & Johnson under licensed rights, are approved in combination therapy for these patients.
Developed using cutting-edge PCR technology, the AmoyDx® PLC Panel enables the simultaneous detection of activating alterations in 11 key driver genes: EGFR, ALK, ROS1, KRAS, BRAF, HER2, RET, MET, NTRK1, NTRK2, and NTRK3. It also identifies actionable mutations in seven of these genes (EGFR, ALK, ROS1, BRAF, MET exon 14 skipping, KRAS, and RET) that are directly associated with 17 targeted therapies for NSCLC. This approval marks a significant advancement in precision oncology, offering rapid and sensitive mutation detection that can substantially improve patient outcomes.
“With this approval, the AmoyDx® PLC Panel can now be used as a CDx to identify patients with unresectable, advanced, or recurrent NSCLC harboring EGFR mutation who may benefit from treatment with Amivantamab plus Lazertinib combination therapy, thereby expanding their therapeutic options,” said Yuko Oi, President and CEO of Riken Genesis; Li-Mou Zheng, Ph.D., Founder and Chairman of AmoyDx; and Tatsuya Ikeda, President and CEO of PREMIA.
