Absorption Systems Publishes CellPort Technologies Study with FDA -- Confirms the Drug Transporters Involved in Disposition of Statin Drugs

Share Article

Absorption Systems utilized its proprietary CellPort Technologies platform in a collaborative study with scientists at the FDA. The results, published online ahead of print in the journal Drug Metabolism and Disposition, demonstrate the ability of CellPort Technologies to predict or explain certain potentially harmful drug-drug interactions.

Absorption Systems today announced the results of another study demonstrating the unique power of the company’s CellPort Technologies® platform to predict the potential for pharmacokinetic drug-drug interactions.

The study, published online in Drug Metabolism and Disposition – one of the leading journals in the field of drug metabolism and pharmacokinetics – examined several statin drugs, which are widely used to lower cholesterol. Using Absorption Systems’ proprietary technology, company scientists, in collaboration with a colleague at the FDA, confirmed what had previously been suspected regarding which drug transporters are responsible for eliminating the drugs from the body. Such results can be important for predicting and understanding drug-drug interactions and toxicity.

CellPort Technologies is a suite of preclinical in vitro test systems designed to provide definitive data regarding interactions between new drugs under investigation and specific transport proteins that have been identified by the FDA as key mediators of drug safety. Absorption Systems scientists used a novel approach to create a panel of human cell lines in which the expression of one efflux transporter at a time is knocked down. It then becomes a simple process of elimination to determine, in a very unambiguous way, which efflux transporter(s) is/are sites of interaction.

“We were very excited to collaborate with the FDA on this research project, especially since the agency helped fund the development of these tools through Phase I and Phase II SBIR grants” said Patrick M. Dentinger, President and CEO of Absorption Systems. “This study demonstrates CellPort’s unique ability to predict or explain potentially harmful drug-drug interactions.”

The collaborative study with the FDA was another demonstration of the power of this approach to explain certain clinical drug-drug interactions. Going forward, drug developers are increasingly utilizing tools such as CellPort proactively to anticipate and avoid such interactions before they occur.

The complete manuscript is available online at http://dmd.aspetjournals.org/content/early/2011/03/29/dmd.111.038075.full.pdf+html and will be in print in Drug Metabolism and Disposition, which is published by the American Society for Pharmacology and Experimental Therapeutics, in the coming months.
