AmoyDx<sup>®</sup> Pan Lung Cancer PCR Panel Approved in Japan as a Companion Diagnostic for LUMAKRAS<sup>®</sup> (Sotorasib)

TOKYO and XIAMEN, November 14th, 2022 -- 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 Amgen’s LUMAKRAS® (sotorasib), for patients with KRAS G12C-mutated, unresectable, advanced and/or recurrent non-small-cell lung cancer (NSCLC) that has progressed after systemic anticancer therapy .

The AmoyDx® PLC Panel is based on polymerase chain reaction (PCR) technology and can simultaneously evaluate the presence of 11 driver genes (EGFR/ ALK/ ROS1/ KRAS/ BRAF/ HER2/ RET/ MET exon 14 skipping/ NTRK1/ NTRK2/ NTRK3 genes) when all genes on the panel are approved as companion diagnostics. The AmoyDx® PLC Panel has received approval for six driver genes (EGFR, ALK, ROS1, BRAF, MET exon 14 skipping, and KRAS G12C) for twelve 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 KRAS G12C positive NSCLC patients for treatment with sotorasib, 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.

About LUMAKRAS® /LUMYKRAS® (sotorasib):
LUMAKRAS®/LUMYKRAS® is an orally available KRASG12C inhibitor. It has demonstrated a positive benefit-risk profile with rapid, deep and durable anticancer activity in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring the KRAS G12C mutation with a once daily oral formulation*1. Amgen is progressing the largest and broadest global KRASG12C inhibitor development program with unparalleled speed and exploring more than 10 sotorasib combination regimens with clinical trial sites spanning five continents. To date, over 6,500 patients around the world have received LUMAKRAS®/LUMYKRAS® through the clinical development program and commercial use. In May 2021, LUMAKRAS® was the first KRASG12C inhibitor to receive regulatory approval, anywhere in the world, with its approval in the U.S., under accelerated approval.
