FREMONT, Calif.--(BUSINESS WIRE)--ARYx Therapeutics Inc. (NASDAQ:ARYX), a biopharmaceutical company, announced today that the database for the EmbraceAC study has been locked and the study remains on schedule, with the efficacy and safety results to be available during the week of July 6, 2009. The study was designed to compare its oral anticoagulation therapy, tecarfarin (previously ATI-5923), against the leading anticoagulant agent, warfarin. The purpose of the trial is to evaluate whether tecarfarin is superior to warfarin in its ability to maintain patients within a target therapeutic range of the level of anticoagulation as measured by INR (International Normalized Ratio). Based upon recent interactions with the U. S. Food and Drug Administration (FDA), ARYx believes this trial could be positioned as one of the required registration studies for tecarfarin.
