Phylogica and Opsona enter into drug discovery collaboration

Dublin, Ireland - 15 March, 2006

Opsona Therapeutics (Dublin, Ireland) and Phylogica (Perth, Australia; ASX:PYC) announce a drug discovery collaboration using Phylogica’s Phylomer® peptide libraries to discover new drugs for targeting inflammatory diseases. 

“Phylomers® are a novel and exciting approach to targeting these inflammatory pathways,” said Dr Heffernan, CEO of Opsona Therapeutics. “We are very pleased to be working with a key player in drug discovery such as Phylogica, whose skills complement our development capabilities”. 

In the agreement with Opsona the relevant Phylomer® compounds will be licensed and developed by Opsona, and Phylogica will share in the revenue stream. Phylogica may receive upfront, milestone and royalty payments under the terms of the agreement.

The collaboration will look at certain Toll-like Receptors (TLRs) and also signalling pathways in T-egulatory cells, which are each applicable for the treatment of a number of inflammatory diseases including asthma, autoimmune diseases and atopic dermatitis.  Similar to the TNF receptor inhibitor drugs that are a billion-dollar market for Rheumatoid Arthritis, TLR receptors and T-regulatory cells hold great promise for treatment of inflammatory diseases and have not yet been fully explored. 

“We are looking forward to working with this global drug development team to discover a new class of Phylomer® drugs that will target Toll-like Receptors and other inflammatory associated pathways” said Dr Stewart Washer, CEO of Phylogica. “Opsona is fast becoming as a world leader in this field, and we are pleased to be collaborating using their exciting technology and expertise. We envisage this will be a very successful collaboration”.
