U.S. patent for Celsis IVT's LiverPool products

Celsis International is pleased to announce that the United States Patent and Trademark Office today issued U.S. Patent No. 7,604,929 to Celsis In Vitro Technologies (Celsis IVT). This patent generally covers processes by which the company creates its unique LiverPool(TM) products for drug discovery research.

The pooling process combines primary cells from multiple donors to create large lots with targeted activity levels. The resulting LiverPool product is flexible, customizable and repeatable, enabling scientists to run multiple studies on various compounds or NCEs anywhere in the world, and at any time, which speeds up decision making and reduces the time and cost of drug research.

"Our LiverPool product is a great example of Celsis IVT's pioneering work in developing ADME-Tox products that meet the research needs of our customers, while helping to take costs out of the drug discovery process," said Judy Madden, vice president of strategic development for Celsis. "We're proud that the US Patent Office has recognized our continued innovation and awarded us this patent."

Celsis IVT has been producing LiverPool products for more than five years and they have been incorporated into the standard research protocols of major pharmaceutical companies around the world. Research conducted with LiverPool has documented its efficacy as a research tool in numerous ADME-Tox assays, including metabolic stability and clearance studies.
