Compugen Ltd. (NASDAQ: CGEN) and DiscoveRx Corporation announced today that they have entered into a collaborative partnership for the purpose of commercializing novel Compugen designed peptides to be matched with specific G protein-coupled receptor (“GPCR”) targets utilizing DiscoveRx GPCR related technologies. The new agreement follows a successful pilot program between the two companies.
Under the terms of the collaboration, DiscoveRx will utilize its PathHunter Platform as well as its extensive suite of additional proprietary cell based GPCR assays and related technologies to match individual peptides in the Compugen GPCR targeted peptide library with specific GPCR drug targets of interest to DiscoveRx’s pharmaceutical company clients and others. Following these activities, peptides of interest will be available for licensing from Compugen under milestone and royalty bearing agreements. The parties have agreed to a revenue sharing financial model providing different pre-arranged sharing percentages for each category of revenue anticipated by the collaboration.
The peptides in Compugen’s GPCR targeted library were predicted through the use of Compugen’s GPCR Peptide Ligand Discovery Platform. During the initial validation activities for this platform, three predicted peptides, CGEN-856, CGEN-855 and CGEN-25009, were subsequently shown to have therapeutic potential in disease animal models of cardiovascular, fibrotic and inflammatory conditions. In addition, Compugen has recently announced that the Pulmonary Fibrosis Foundation will fund further studies to evaluate the potential of CGEN-25009 for treating lung fibrosis.
This successful initial validation of the GPCR peptide platform, and subsequent enhancements and extensions of the platform prompted Compugen to utilize it to predict and synthesize a GPCR targeted peptide library, currently containing more than 900 peptides predicted to have a high likelihood of modulating GPCR targets. The analysis of this unique peptide library with DiscoveRx’s PathHunter Platform and broad range of GPCR assays and related technologies is the basis for this collaboration. The GPCR family of membrane protein receptors is the largest family of known drug targets, and an estimated 40% of prescription drugs currently available are thought to modulate GPCRs. Furthermore, newly discovered GPCR peptide ligands in the past have shown a high probability of being successfully developed into new drugs.
