Duska Therapeutics Plans 505(b)(2) NDA Filing Route for ATPace(TM)

Fri Apr 25, 2008 8:00am EDT
LA JOLLA, Calif., April 25 /PRNewswire-FirstCall/ -- Duska Therapeutics,
Inc. (OTC Bulletin Board: DSKA) ("Duska" or the "Company"), a biotechnology
company developing medical products based on adenosine 5'-triphosphate (ATP)
and P2 receptor-related technologies, announced today that the Company's
management and clinical and regulatory consultants met on April 16 with
members of the United States Food and Drug Administration (FDA) Division of
Cardiovascular and Renal Products. The purpose of the meeting was to discuss
the appropriate regulatory pathway for filing a marketing application of
ATPace(TM) as an antiarrhythmic drug for the acute termination of paroxysmal
supraventricular tachycardia (PSVT).
    Based on discussions held during the meeting and prior written
communications between Duska and the FDA, the Company believes that the FDA
would consider a New Drug Application (NDA) under section 505(b)(2) for
ATPace(TM) subject to additional clinical data to be furnished by the Company.
The 505(b)(2) NDA relies in part upon relevant published data obtained by
entities other than the Company.
    Dr. James Kuo, Duska's Chairman and CEO, said, "I am pleased to report
that this meeting with the FDA was both positive and constructive. Together
with our CRO, Cato Research, Inc., we have already commenced activities aimed
at the generation of the supplemental data requested by the FDA. The 505(b)(2)
NDA filing provides an expedited route for potential approval of ATPace(TM),"
he added.
    Dr. Amir Pelleg, Duska's President and Chief Scientific Officer, stated,
"It has been our goal to commercialize the first ATP-based drug in the United
States and I believe we are now much closer to attaining that goal as a result
of this meeting. Formulations of ATP, which is the active ingredient in
ATPace(TM), have been used for over 50 years in Europe in the treatment of
PSVT. I am confident that our drug would manifest a safety and efficacy
profile similar to that of the European formulations."
    About ATPace(TM)
    ATPace(TM) is Duska's investigational intravenous pharmaceutical
formulation of ATP for the acute treatment of paroxysmal supraventricular
tachycardia (PSVT). The bradycardic (heart rate slowing) effect of ATP, in
particular its transient blockade of atrio-ventricular nodal conduction, has
been shown in multiple published clinical studies to terminate re-entrant PSVT
involving the atrio-ventricular node.
    About PSVT
    PSVT (paroxysmal supraventricular tachycardia) is a rapid regular heart
rate originating in the atria.  It has been estimated that there are 89,000
new cases per year in the United States alone. PSVT is one of the most common
cardiac arrhythmias.
    About Duska Therapeutics, Inc.
    Duska Therapeutics, Inc., based in La Jolla, California, is an emerging
biotechnology company that is focused on the development of therapeutic,
medical device and diagnostic products related to adenosine 5'-triphosphate
(ATP) and cell-surface P2 receptors (P2R). Duska owns or has exclusive license
rights to a number of proprietary products, four of which are currently in
