Coley Pharmaceutical Group Grants Dynavax License for Commercialization of HEPLISAV(TM)

WELLESLEY, Mass. and BERKELEY, Calif., June 28 (HSMN NewsFeed) -- Coley Pharmaceutical Group, Inc. (Nasdaq: COLY ) and Dynavax Technologies Corporation (Nasdaq: DVAX ) today announced they have entered into a license agreement relating to certain TLR Therapeutics(TM) patents from Coley.

Under the terms of the agreement, Dynavax receives a non-exclusive license under Coley's immunostimulatory oligonucleotide patent estate for the commercialization of HEPLISAV(TM), a hepatitis B prophylactic vaccine, currently in Phase 3 clinical trials. Coley will receive a $5.0 million up- front payment. Coley is also eligible to receive up to an additional $5.0 million upon regulatory approvals of HEPLISAV, as well as royalty payments for any future sales of HEPLISAV.

About HEPLISAV and Hepatitis B

HEPLISAV is currently being evaluated in a Phase 3 clinical trial in Canada and in Europe. The multi-center trial, known as PHAST (Phase 3 HeplisAv Short-regimen Trial), is comparing a two-dose regimen of HEPLISAV administered at 0 and 1 month to the conventional three-dose regimen of Engerix-BŪ. The enrollment target of the study is approximately 2,000 subjects, ages 11 to 55 years. Dynavax expects to submit a BLA in 2008 for approval of the product with a database of approximately 4,000 patients

In several previous clinical studies, HEPLISAV has been shown to provide seroprotection against hepatitis B faster and with fewer doses than conventional hepatitis B vaccines. Additionally, HEPLISAV has provided 100% seroprotection in all subjects who have received the full regimen, including those who are difficult-to-immunize.

About Coley's TLR Therapeutics(TM)

Coley's TLR Therapeutics are a new class of investigational drug candidates that target certain immune cells through Toll-like receptors. The patents licensed today to Dynavax relate to Coley's Toll-like receptor 9(TLR9) agonist technology that induce enhanced antigen-specific antibody and T-cell immune responses when used in combination with vaccines. Coley's TLR9 agonist drug candidate has been included in approximately 35 clinical trials of vaccines in development for use in various cancer indications, infectious diseases and biowarfare defense. The most advanced clinical program with Coley's TLR9 agonist vaccine adjuvant candidate is a planned Phase III clinical trial under the direction of GlaxoSmithKline (GSK) as part of a treatment for resectable, early stage lung cancer.
