BASKING RIDGE, N.J., Nov. 2, 2010 /PRNewswire/ -- Regado Biosciences, Inc., a privately held company leading the development of antithrombotic aptamers with active control agents, announced that Steven L. Zelenkofske, D.O., F.A.C.C., Senior Vice President and Chief Medical Officer, presented an abstract at the American College of Chest Physicians (ACCP) Coagulation and Heart Disease Sessions on November 2, 2010 in Vancouver, BC, Canada.  The abstract is titled "Sustained Inhibition of Factor IXa by Subcutaneous RB006 with Active Reversal: First-in-Human Experience with the REG2 System."

The REG2 system is intended for use in venous thrombosis indications.  This initial Phase 1 study was the first successful subcutaneous application of an aptamer in humans.  It demonstrated that a single subcutaneous injection of RB006 (aka pegnivacogin) resulted in dose-dependent inhibition of Factor IXa with effects that persisted longer than one week after injection. The data is promising for future development of REG2.

The abstract is coauthored by Steven L. Zelenkofske, D.O., Christopher P. Rusconi, Ph.D. and Carolyn M. Darmiento, MS, all from Regado Biosciences; and Richard C. Becker, MD, Duke University School of Medicine, Durham, NC and William Wargin, Ph.D., President of PK-PM Associates, LLC.
