Regado Biosciences, Inc. Continues to Expand Its Patent Portfolio By Announcing Issuance of a New Patent for Its Product Candidates, the REG1 and REG2 Anticoagulation Systems

BASKING RIDGE, N.J., May 25 /PRNewswire/ -- Regado Biosciences, Inc., a privately held company leading the development of antithrombotic aptamers with active control agents, today announced issuance of another key patent related to their proprietary technology.  This new patent includes coverage for RB007, the modulator or active control component of Regado's innovative product candidates, the REG1 and REG2 anticoagulation systems.  The allowed claims in U.S. Patent No. 7,723,315 broadly cover modulators that are capable of binding to certain blood coagulation Factor IX/IXa inhibiting aptamers and include both composition of matter and methods of use claims.  The term for this patent extends to April 2025.

ABOUT REGADO BIOSCIENCES

Regado Biosciences is pioneering a new therapeutic technology with the creation and development of two-component drug systems.  Each system comprises a nuclease-stabilized RNA aptamer that can be controlled directly by its specific and complementary oligonucleotide active control agent.  This technology is being applied to injectable antithrombotics (including anticoagulants and antiplatelet agents) in the acute and sub-acute care setting, a multi-billion dollar market in need of therapeutics with improved safety profiles and a greater degree of therapeutic control.  Regado's technology is designed to give physicians the ability to actively and directly control each system's therapeutic effect providing a safe and unique approach to personalized medicine.

ABOUT REG1 and REG2  

Regado's lead program, the anticoagulant system REG1, consists of two parenteral agents both administered by IV bolus, the first being a potent highly selective Factor IXa inhibitor (RB006) and the second being its complementary active control agent (RB007).  RB007 can be used to selectively completely or partially reverse the anticoagulant effect of RB006.  REG1, presently in phase 2b clinical trial, is intended for application in arterial thrombosis applications, initially in Acute Coronary Syndrome patients undergoing Percutaneous Coronary Intervention.  REG2, Regado's second product candidate, consists of a subcutaneously administered depot formulation of RB006 paired with the IV bolus formulation of RB007.  REG2 recently completed single escalating dose phase 1 clinical testing (the first successful subcutaneous application of an aptamer in humans) and is planned to be studied in a multiple escalating dose clinical trial later in 2010.  It is intended for use in venous thrombosis indications such as venous thromboembolism (VTE) prophylaxis in patients undergoing abdominal surgery.  Information pertaining to Regado's clinical programs may be obtained at www.clinicaltrials.gov.

ABOUT APTAMERS

RB006 is a member of a class of compounds called aptamers.  Aptamers are single stranded oligonucleotides that adopt a specific conformation enabling direct, specific inhibition of the targeted protein.  A key unique feature of aptamers derives from the fact that they are formed from nucleic acids.  As such, their pharmacologic activity can be controlled by a matched, complementary oligonucleotide active control agent (the Watson-Crick base pair complement of a fraction of the agent to be controlled), which can bind to the aptamer, removing it from its target and reversing it biologic effects.
