Koronis Pharmaceuticals Raises $20 Million

Jun 28, 2007, 01:00 ET from Koronis Pharmaceuticals, Inc.

    SEATTLE, June 28 /PRNewswire/ -- Koronis Pharmaceuticals, Inc., today
 announced the closing of a $20 million Series D financing to further the
 development of antiviral therapeutics based on Viral Decay
 Acceleration(TM). The financing was led by Pacific Horizon Ventures and
 joined by Asset Management Company.
     The Series D financing will support Phase 2a proof-of-concept studies
 for the Company's lead product candidate, KP-1461, a novel, oral
 small-molecule therapeutic that works through Viral Decay Acceleration(TM)
 (VDA) for the treatment of human immunodeficiency virus (HIV) infection.
 The first of two planned Phase 2a trials is now underway, and the Company
 targets completion of the trials in 2008.
     "The Phase 2a trials are designed to confirm the therapeutic effect of
 VDA and validate KP-1461 as an anti-HIV drug suitable for late-stage
 clinical development," said Donald Elmer, Pacific Horizon Ventures managing
 partner and interim CEO of Koronis. "As a novel drug mechanism against
 serious viral infections, VDA is an approach that has the potential to
 significantly change the current treatment paradigm."
     "KP-1461 has demonstrated the potential to ablate HIV infection in
 vitro and was generally safe and well tolerated in Phase 1 trials," said
 Stephen Becker, M.D., Chief Medical Officer of Koronis. "We look forward to
 the advancement of these trials at clinical sites throughout the country
 and are hopeful results will support the positive findings demonstrated in
 preclinical studies."
     About Viral Decay Acceleration(TM)
     VDA is a novel therapeutic mechanism with application against HIV and
 other viral infections. VDA increases the virus' naturally high mutation
 rate, causing an accumulation of mutations within the viral genome. This
 leads to impaired viral function and collapse of the viral population.
 Unlike conventional antiretroviral agents, KP-1461's action does not
 directly inhibit viral enzymes, a feature which may significantly limit the
 virus' ability to develop resistance against the drug.
