Guardant360® CDx is the first blood-based companion diagnostic to be approved in Japan for the detection of EGFR exon 20 insertion mutations
TOKYO, Aug. 30, 2024 /PRNewswire/ -- Guardant Health Japan Corp. (HQ: Minato-ku, Tokyo/ Representative Director: Mika Takaki), a leading precision oncology company, today announced that the Ministry of Health, Labour and Welfare (MHLW) in Japan has approved Guardant360® CDx as a companion diagnostic to identify EGFR exon 20 insertion mutations in patients with inoperable or recurrent non-small cell lung cancer (NSCLC) for consideration of treatment with amivantamab-vmjw combined with chemotherapy. This approval makes the Guardant360 CDx comprehensive genomic profiling panel the first blood-based companion diagnostic to be approved in Japan for the detection of EGFR exon 20 insertion mutations. Janssen Pharmaceutical K.K. (HQ: Chiyoda-ku, Tokyo/ Representative Director: Shuhei Sekiguchi), a Johnson & Johnson company, is currently seeking regulatory approval for the use of amivantamab-vmjw, a precision medicine, in Japan.

Lung cancer is one of the most prevalent and deadly cancers globally, with non-small cell lung cancer (NSCLC) representing approximately 80-85% of all lung cancer cases.1,2 In Japan, more than 136,000 cases of lung cancer were newly diagnosed in 2022.3 In a retrospective analysis, the Guardant360 test identified EGFR exon 20 insertion mutations in 2.4% of East Asian patients with NSCLC, including those from Japan.4 This regulatory approval of the test gives patients in Japan with inoperable or recurrent NSCLC harbouring EGFR exon 20 insertion mutations a greater opportunity to access targeted treatment options, such as amivantamab-vmjw combined with chemotherapy.
Guardant360 CDx was approved by MHLW in March 2022 for comprehensive genomic profiling in patients with advanced solid tumours. The test examines 74 cancer-related genes and is approved as a companion diagnostic for multiple cancer drugs approved in Japan.

About Guardant360® CDx
Guardant360® CDx is a liquid biopsy test that uses next generation sequencing to analyse circulating tumour DNA (ctDNA), which is produced when tumours shed small pieces of their genetic material into the bloodstream. The test provides comprehensive genomic profiling results from a simple blood draw, helping oncologists move beyond the limitations of tissue biopsies to obtain clinically relevant information in time to match patients to the optimal personalised treatment.
