Asuragen Forms Alliance With Life Technologies To Develop And Distribute Diagnostic Test For Chronic Myeloid Leukemia

Asuragen, Inc. (Asuragen), a fully integrated RNA-based therapeutic and diagnostics company, has entered into an exclusive agreement with Life Technologies Corporation ( Life Technologies) to develop and distribute worldwide an in-vitro diagnostic test intended to aid clinicians in the monitoring and treatment of individuals afflicted with chronic myeloid leukemia (CML).

As part of the agreement, Asuragen will pursue CE marked-IVD registration in Europe and regulatory clearance in the US. The diagnostic test will then be distributed by Life Technologies and run exclusively on the Applied Biosystems 7500 Fast Dx Real-Time PCR Instrument, which originally received 510(k) clearance from the FDA in late 2008 in conjunction with the Center for Disease Controls H5N1 assay.

Asuragen’s in-vitro diagnostic test, a BCR/ ABL1 assay, will simultaneously detect and quantify BCR/ABL1 fusion transcripts (b2a2, b3a2, and e1a2) in a single reaction. The BCR-ABL1 fusion gene arises from a specific chromosome translocation, known as the Philadelphia chromosome or t(9:22).

The resulting BCR/ABL1 fusion transcripts are present in approximately 95% of CML and 25-30% of acute lymphoblastic leukemia cases. If present, the expression level of the fusion transcript or its ratio to a reference transcript may be used to monitor disease progress. Monitoring the level of BCR/ABL1 may be helpful for both prognosis and management of Gleevec, Sutent and Sprycell kinase therapies in patients with leukemia disease.

Rollie Carlson, president of Asuragen, said: “Our development of a BCR/ABL1 test leverages both our expertise in molecular diagnostics development and our proprietary Armored RNA technology. With streamlined multiplex workflow and inclusion of Armored RNA controls in the kit, the assay will have both broad target coverage and dynamic range, while offering unmatched standardization for both internal and external assay calibration.

“We are pleased to partner with Life Technologies, and believe their strong molecular instrumentation offerings and broad commercialization capabilities will lead to adoption of this test throughout the world.”

Asuragen’s BCR/ABL1 assay will have the advantage of both detecting and quantifying e1a2, b2a2 and b3a2 fusion transcripts in a single reaction. Streamlined reagent formulation, multiplex assay format and inclusion of Armored RNA Quant external calibrators improve the workflow and increase the number of specimens that can be tested per run.

Co-detection of ABL1 and inclusion of an exogenous Armored RNA Quant process control enable reporting of BCR/ABL1 to ABL1 ratio for standardization to the International Scale as well as reporting of absolute BCR/ABL1 copy number.
