AmoyDx® Pan Lung Cancer PCR Panel  Approved in Japan as a Companion Diagnostic for selpercatinib RET fusion positive NSCLC

TOKYO and XIAMEN, March 27th, 2023 -- 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 for RET fusion-positive non-small cell lung cancer (“NSCLC”), for selpercatinib capsules 40 mg and 80 mg.  

The AmoyDx® PLC Panel is based on polymerase chain reaction (PCR) technology and can simultaneously evaluate the presence of activation alterations in 11 driver genes (EGFR/ ALK/ ROS1/ KRAS/ BRAF/ HER2/ RET/ MET/ NTRK1/ NTRK2/ NTRK3 genes) when all genes on the panel are approved as companion diagnostics. The AmoyDx® PLC Panel has received approval for the identification of activating alterations in seven driver genes (EGFR, ALK, ROS1, BRAF, MET exon 14 skipping, KRAS, and RET) for twelve (12) associated targeted therapies in NSCLC. With its high sensitivity and short turnaround time, the AmoyDx® PLC Panel is expected to be an important clinical diagnostic in guiding treatment opportunities for NSCLC patients.

 “With this approval, the AmoyDx® PLC Panel can now be used to identify RET fusion-positive NSCLC patients for treatment with selpercatinib, thereby expanding their therapeutic options. We look forward to developing and commercializing additional, new therapy options for Japanese patients,” said Kenji Iwakabe, President and Chief Executive Officer of Riken Genesis, Li-Mou Zheng, Ph.D., Founder and Chief Executive Officer of AmoyDx and Wenn Sun, Ph.D., Founder and President of PREMIA.
