Tel Aviv, Israel and Fremont, California - November 29, 2011 – Compugen Ltd. (NASDAQ: CGEN) and DiscoveRx Corporation announced today that they have entered into a collaborative partnership for the purpose of commercializingnovel 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.
The two companies recently completed a pilot project whereby the DiscoveRx technologies were applied to analyze the Compugen designed peptides with a small subset of GPCR targets. This pilot resulted in promising initial results for a number of library peptides that were shown to modulate specific GPCR targets, thus demonstrating both the library’s potential as a reservoir of therapeutically relevant peptides, as well as the ability of DiscoveRx’s functional GPCR assays to identify novel peptide/GPCR target interactions.
Dr. Pyare Khanna, CEO of DiscoveRx Corp., stated, “We see this collaboration as a unique opportunity to address a key drug target class through a combination of DiscoveRx’s most comprehensive and market leading GPCR cell based assay platforms, and Compugen’s leading predictive capability for peptide discovery.Based on these synergistic competitive advantages, and the demonstrated success of the recently completed pilot program, we believe that via this partnership, pharmaceutical and biotech companies will be able to gain access to novel peptides for both research and product development purposes. DiscoveRx will continue to innovate in the field of GPCR drug discovery, and is pleased to now bring to the industry, together with Compugen, novel solutions in this key area of high industry interest and need.”
“Compugen is very enthusiastic regarding this collaboration with DiscoveRx, one of the leading companies in the GPCR screening field, for the commercialization of Compugen-designed molecules from our GPCR peptide library," said Anat Cohen-Dayag, Ph.D., Compugen's President and CEO.
Dr. Cohen-Dayag continued, "As previously disclosed, Compugen is focusing its discovery and development efforts towards addressing unmet medical needs in our focus areas of oncology and immunology through the use of novel protein and antibody therapeutics.However, as part of the development and validation activities associated with establishing our broadly applicable predictive discovery capabilities, a number of very promising discoveries were made that have significant potential in other areas.Therefore, in recent months, we have been in various discussions for arrangements with other organizations to advance certain of these earlier discoveries, including a number related to potential peptide therapeutics, largely without the need for further Compugen financial resources, such as this very promising collaboration with DiscoveRx being announced today.”
About Compugen’s GPCR Peptide LibraryThe more than 900 peptide molecules in Compugen’s GPCR peptide library were predicted through the use of Compugen’s GPCR Peptide Ligand Discovery Platform.The initial validation activities for this platform resulted in the predictive discovery of a number of novel peptides that were subsequently shown to have therapeutic potential in disease animal models of cardiovascular, fibrotic and inflammatory conditions.Further enhancements and extensions during, and subsequent to, the initial validation, have resulted in the current platform, which relies on a series of sequential computational biology models and machine learning capabilities for the prediction and selection of product candidates. The platform incorporates a proprietary model of the “peptidome”, an in silico prediction of putative human peptides, which includes thousands of novel predicted human peptide sequences, based on predicting cleavage sites in precursor proteins. The discovery platform utilizes proprietary machine-learning algorithms to analyze this peptidome and to identify peptides likely to activate GPCRs.
About DiscoveRx’s PathHunter Platform and GPCR related Technologies DiscoveRx’s innovative approach to GPCR signaling assay development, using a simple, homogeneous, chemiluminescent, read-out based on β-galactosidase-based enzyme fragment complementation (EFC), is core to the success of many drug discovery programs. The emerging field of GPCR drug discovery is necessitating the analysis of GPCRs using multiple assay approaches. From the traditional second messenger signaling assays to the novel, universal β-arrestin recruitment assays for known and orphan GPCRs to the next generation platforms for studying GPCR internalisation and heterodimerisation, DiscoveRx is addressing current and emerging drug discovery needs through innovative GPCR assays and profiling services and by offering more than one signaling assay platform for a single GPCR target (www.discoverx.com/gpcrs).
Compugen is a leading therapeutic product candidate discovery company, currently focused on biologics-based therapy to address important unmet needs in the fields of immunology and oncology, either for Compugen or its partners. Unlike traditional high throughput trial and error experimental based drug candidate discovery, Compugen’s discovery efforts are based on systematic and continuously improving in silico (by computer) product candidate prediction and selection followed by experimental validation, with selected product candidates being advanced in its Pipeline Program to the pre-IND stage. Compugen’s in silico predictive models utilize a broad and continuously growing infrastructure of proprietary scientific understandings and predictive platforms, algorithms, machine learning systems and other computational biology capabilities.The Company’s business model primarily involves collaborations covering the further development and commercialization of Compugen-discovered product candidates and various forms of “discovery on demand” arrangements, in both cases providing Compugen with potential milestone payments and royalties on product sales or other forms of revenue sharing. In 2002, Compugen established an affiliate, Evogene Ltd. (www.evogene.com) (TASE: EVGN.TA), to utilize certain of the Company's in silico predictive discovery capabilities in agricultural biotechnology.
