Tests identify genetic mutations that can affect patient response to certain cancer drugs.
Roche and DxS Ltd. have signed an exclusive distribution agreement for the DxS TheraScreen K-RAS Mutation Test and TheraScreen EGFR 29 Mutation Test. The tests are intended, when considered with other clinically relevant factors, to aid doctors in identifying suitable patients likely to benefit from a specific cancer therapy based on their mutation status.
Under the terms of the agreement, Roche is granted exclusive world-wide distribution rights for the K-RAS Test, which has CE Mark certification in Europe. For the EGFR test, which also has CE Mark certification, Roche is granted exclusive distribution rights for all global markets except the United States, Canada, Mexico, and Hong Kong.
The TheraScreen K-RAS Mutation Test was the first clinically validated, CE-Mark certified companion diagnostic for tumor-specific mutations in patients with colorectal cancer. In addition, some drugs used to treat colorectal and other cancers are only indicated for patients who have a non-mutated (or “wild-type”) K-RAS gene. The test detects seven mutations in codons 12 and 13 of the K-RAS oncogene, which are frequently found in many cancer types. These mutations are common in colorectal cancer, pancreatic cancer, lung adenocarcinoma, gall bladder cancer, bile duct cancer and thyroid cancer.
The TheraScreen EGFR 29 Test is designed to enable detection of 29 of the most common somatic mutations in the EGFR gene and detects mutations with greater sensitivity than sequencing. Recent studies in non-small cell lung cancer have shown that some patients carry somatic mutations in the epidermal growth factor receptor (EGFR) gene. These mutations may correlate with responsiveness to the EGFR tyrosine kinase inhibitors, with some mutations having a sensitizing effect and others being linked to resistance. Ongoing trials in metastatic NSCLC are investigating whether such a test could aid doctors in selecting lung cancer patients suitable for first line treatment with EGFR tyrosine kinase inhibitors, such as Tarceva, in the future.
DxS is a UK-based personalized medicine company providing molecular diagnostics to aid doctors and drug companies in selecting therapies for patients. DxS offers products, technology and services to the healthcare industry to enable the delivery of safe and effective medicines. Working predominantly in the field of cancer, DxS has a range of companion diagnostic and research kits that detect mutations in oncogenes associated with cancer drug response. The TheraScreen® range of CE Mark certified diagnostic products includes kits that detect mutations in the EGFR and K-RAS genes. Tumor mutation products are available for research use for EGFR, RAS, RAF, BCR-ABL and other genes that show a correlation between patient mutation status and drug response. DxS also provides a genetic analysis service to support clinical development. For more information, visit http://www.dxsdiagnostics.com.
