Coley Pharmaceutical Group Receives $3.0 Million Milestone Payment from GlaxoSmithKline

WELLESLEY, Mass., Oct. 26  /PRNewswire-FirstCall/ -- Coley Pharmaceutical Group, Inc. (NASDAQ:COLY), today announced that the company has received a $3.0 million milestone payment from GlaxoSmithKline (GSK) associated with the initiation of GSK's Phase III clinical trial in non-small cell lung cancer (NSCLC) of an immunotherapeutic cancer vaccine containing Coley's VaxImmune(TM) vaccine adjuvant.

In June 2007, GSK announced the launch of the largest Phase III clinical trial in lung cancer to evaluate the MAGE-A3 Antigen-Specific Cancer Immunotherapeutic (MAGE-A3 ASCI) in patients with early stage, completely resected NSCLC.  VaxImmune is one of the components of MAGE-A3 ASCI, intended to increase an anti-tumor immune response.  The randomized, double-blind, and placebo-controlled Phase III clinical trial, known as the MAGRIT trial (MAGE- A3 as Adjuvant Non-Small Cell Lung Cancer Immunotherapy) will target enrollment of about 2,270 patients with stage IB, II or IIIA resectable NSCLC. The primary endpoint of the trial is disease-free survival.  The $3 million development milestone was triggered by the initiation of this Phase III trial.

VaxImmune is Coley's proprietary TLR9 agonist designed to induce both an enhanced antibody response and a potent killer T cell immune response when used in conjunction with vaccines in order to achieve and sustain a clinical response without compromising safety.  Coley has granted GSK worldwide licenses for the use of VaxImmune in GSK's vaccines in development for certain cancers and infectious diseases.
