>>HAYWARD, Calif., Dec. 13 /PRNewswire-FirstCall/ -- Aradigm Corporation (Nasdaq: ARDM - News) today announced that it has entered into an agreement with Defence R&D Canada for the aerosolized delivery of liposomal-encapsulated ciprofloxacin to develop a treatment and prophylaxis for serious respiratory infections, including, but not limited to, bioterror-related inhalation anthrax. The drug will be delivered by Aradigm's AERx® technology platform.
Under the terms of the contract, Defence R&D Canada (DRDC) is funding Aradigm's product and formulation development work and initial pre-clinical studies, with work scheduled to begin in January 2005. Stemming from this agreement, Aradigm will hold the intellectual property associated with the inhalation of liposomal ciprofloxacin, an anti-infective agent used in multiple disease states.
"We are pleased to be in partnership with DRDC and that they recognize the delivery benefits of the AERx System in this area of great international importance," said Dr. Bryan Lawlis, President and Chief Executive Officer of Aradigm. "This agreement is intended to build upon the proof-of-principle work already completed successfully by DRDC. The goal of DRDC and Aradigm is to complete pre-clinical studies next year and move as rapidly as possible into human safety studies. With these agreements, Aradigm now owns a proprietary and potentially efficacious formulation of an anti-infective for the treatment of a wide range of respiratory diseases with significant commercial potential."
In addition to the DRDC contract, Aradigm has been granted an exclusive worldwide license by Inex Pharmaceuticals Corporation to their intellectual property relating to the manufacturing of liposomal ciprofloxacin.
"Encapsulation of ciprofloxacin in liposomes results in a liquid formulation that can be readily aerosolized and delivered efficiently to the lung as well as dramatically increasing the residence time of the ciprofloxacin within the lung," said Dr. Stephen Farr, Aradigm's Chief Scientific Officer. "For local infections of the lung, our goal is to develop liposomes that release the ciprofloxacin at a sustained rate to enhance the killing of pathogens. Beyond the initial technical development, the contract enables Aradigm to evaluate the efficacy of inhaled liposomal ciprofloxacin in established animal models of respiratory infections. Data from these studies may provide the opportunity to proceed into human studies for the treatment of respiratory infections such as those prevalent in patients with cystic fibrosis."<<
