Atlantic Research Group Successfully Completes Work on Phase III Randomized, Multi-Center Clinical Trial Facilitating Lev Pharmaceuticals' BLA Submission.

STAUNTON, Va. -- Atlantic Research Group ("ARG") played a critical role in the BLA submission made to the U.S. Food and Drug Administration (FDA) by Lev Pharmaceuticals.

Lev Pharmaceuticals submitted a BLA to the FDA on July 31, 2007, after the completion of the pivotal U.S. Phase III trial of C1 inhibitor for the treatment of hereditary angioedema (HAE), to be marketed as Cinryze(TM). Lev relied on ARG's experienced staff and TrialVista(TM), ARG's recently launched Clinical Trial Management System (CTMS), to assist in the timely completion of the clinical trial.

"ARG was instrumental in helping Lev Pharmaceuticals meet timelines for our BLA submission to the FDA. Their dedicated, thorough work, management of multiple vendors, efficient monitoring teams and TrialVista(TM) CTMS implementation were critical assets for Lev Pharmaceuticals as we prepared for this filing," said Jason Bablak, Lev's Vice President of Regulatory Affairs & Product Development.

Lyle Camblos, ARG Managing Partner said, "This is an exciting time for HAE patients in the United States and we are excited to have been a part of the management of the clinical trial and subsequent BLA submission of Cinryze(TM)."

ARG also continues to assist Lev Pharmaceuticals' with roll-over studies being conducted until FDA approval for Cinryze(TM) is received.
