Zogenix and Battelle to Present Positive, New Data Demonstrating Value of Needle-Free Injection for Biologics

DosePro Studies to be Presented at 2013 AAPS National Biotechnology Conference


Zogenix, Inc. (Nasdaq:ZGNX) and Battelle Memorial Institute today announced new data supporting the value of the DosePro® needle-free injection technology in the delivery of biologics. The positive, new data will be presented in four poster presentations, including two posters co-authored by MedImmune, LLC, the worldwide biologics research and development arm of AstraZeneca plc, and Zogenix; and two posters co-authored by Battelle and Zogenix, at the 2013 American Association of Pharmaceutical Scientists (AAPS) National Biotechnology Conference, May 20-22, 2013 in San Diego.

The data presented in these posters show that the DosePro technology is compatible with monoclonal antibodies formulations and a range of biologic formulation viscosities which are challenging to deliver via standard autoinjector technologies. The studies found that injection of these formulations were within the acceptable criteria for injection time and peak pressure and that there were no changes in molecular integrity, observable tertiary structure, purity or potency following injection. The data also show that needle-free technology such as DosePro has the potential to positively impact patient acceptance of self-injectable therapies, leading to greater adoption and adherence of subcutaneously administered biologics.

John Turanin, Vice President and General Manager, DosePro Technology, at Zogenix, commented, "This new data represents an important step in addressing the need for delivery technology for biologics by demonstrating DosePro's compatibility with the viscous formulations and the impact of needle-free delivery on patient confidence. We believe the AAPS National Biotechnology Conference will be an excellent forum to introduce the DosePro system to potential biopharmaceutical partners looking for innovative delivery technology solutions for their current and future self-injection therapies."

The four posters to be presented at the AAPS National Biotechnology Conference include:

  • In Vitro Integrity of Two Recombinant Human Monoclonal Antibodies after Instantaneous Injection by DosePro® Delivery Technology; Poster# M1012
  • Injection Performance Assessment of Monoclonal Antibody Formulation Viscosity mimics Using an Instantaneous Injection Technology; Poster# M1013
  • Adoption, Adherence, and Preferences Regarding Injectable Drug Delivery by Patients with Rheumatoid Arthritis: Results of a Research Survey; Poster# T2010
  • Devices for Delivery of Viscous Protein Formulations and their Impact on Protein Structure; Poster# T2012

Battelle will feature the DosePro system at its booth (#413) at the AAPS National Biotechnology Conference. For more information on licensing opportunities using the DosePro platform contact Battelle at 1-800-201-2011 or

About DosePro®

The DosePro system is a first-in-class, easy-to-use drug delivery system designed for self-administration of a pre-filled, single dose of sterile liquid drug, subcutaneously, without a needle. The platform is currently used by Zogenix's first commercial product, SUMAVEL DosePro®. The Company believes that DosePro offers several benefits to patients compared to other subcutaneous needle-based delivery methods, and that it has the potential to become a preferred delivery option for patients and physicians. These benefits include less anxiety or fear due to the lack of a needle, easier disposal without the need for a sharps container, no risk of needle stick injury or contamination, an easy-to-use three step administration process, no need to fill the device prior to use, reliable performance, discreet use and portability. In several clinical trials and market research studies, DosePro has been shown to be preferred by patients over conventional needle-based systems.
