Menarini-Silicon Biosystems to Acquire CELLSEARCH® CTC System

Only FDA-Cleared CTC test to join Company’s Portfolio of Diagnostics

Bologna, Italy and San Diego, CA, Dec 20, 2016 - Menarini-Silicon Biosystems today announced they have signed an agreement to purchase all the assets and relevant business related to the CELLSEARCH® Circulating Tumor Cell (CTC) system from Janssen Diagnostics, LLC.  CELLSEARCH® is used to help manage patients with metastatic breast, prostate, and colorectal cancers.  It is the only FDA-cleared CTC test, and has also been approved by China’s FDA for use in monitoring breast cancer patients. Financial details were not disclosed.

CELLSEARCH® system will join Menarini-Silicon Biosystems’ family of advanced diagnostics, which includes the Company’s flagship DEPArray™ System.  DEPArray™ is a rare-cell detection and isolation technology that is used globally in a number of therapeutic areas, including oncology.  With both DEPArray™ and CELLSEARCH® in its portfolio, Menarini-Silicon Biosystems will be able to provide CTC detection on an FDA-cleared platform, and give oncologists and researchers access to unparalleled molecular characterization capabilities.  Together, the two technologies provide a unique opportunity to advance next-generation, personalized medicine strategies.

“We are excited to welcome CELLSEARCH® to the Menarini-Silicon Biosystems portfolio,” commented Lucia Aleotti, Chairman of Menarini Group and Giuseppe Giorgini, CEO, Menarini-Silicon Biosystems.  “The combined capabilities of CELLSEARCH® together with our DEPArray™ System will enhance our potential to enable meaningful advances in the field of personalized medicine.” 

Under terms of the agreement, when the closing will occur, Menarini-Silicon Biosystems will seek to retain many of the Janssen Diagnostics employees in roles dedicated to CTCs, and assume operation of Janssen Diagnostics’ CLIA-certified laboratory in Huntingdon Valley, Pennsylvania. The two companies will work closely to transition the business across the many global markets where CELLSEARCH® is available.
