RASKET KIT is the Japan’s first IVD test kit which can detect mutations in exon 2 (codon 12, 13), exon 3 (codon 59, 61), and exon 4 (codon 117,146) in both KRAS and NRAS genes in a single assay. MBL obtained CE mark approval in June, 2014 to market the product in Europe, and regulatory approval in Japan on January 27, 2015, as stated above.
The research group consisting of nine medical institutions in Japan carried out a comprehensive genetic analysis (BREAC trial) to identify potential new biomarkers of various mutations outside of KRAS exon 2 which correlate with poor therapeutic effects of anti-EGFR treatment on unresectable, advanced, recurrent colorectal cancer. Based on the results and findings from the BREAC trial and other studies, G&G Science and the multicenter study group led by Dr. Atsushi Ohtsu (Director of Exploratory Oncology Research & Clinical Trial Center), Dr. Katsuya Tsuchihara (Chief of Division of Translational Research, Exploratory Oncology Research & Clinical Trial Center), and Dr. Takayuki Yoshino (Chief of Department of Gastrointestinal Oncology, Hospital East) developed RASKET KIT which can simultaneously detect those newly found RAS mutations. The research and development was supported by strategic SME/venture development grant funding (2011) from the Japan Science and Technology Agency’s A-STEP program.
‘‘None of existing diagnostic kits could simultaneously detect multiple RAS gene mutations. RASKET KIT helps clinicians correctly select candidate patients for anti-EGFR antibody treatment and thus provide more appropriate and individualized treatments.’’ said Dr. Takayuki Yoshino, the principal investigator of the clinical evaluation trial for RASKET KIT.
