(Nasdaq: TELK) and Genaissance Pharmaceuticals, Inc. (Nasdaq: GNSC) announced today that they have successfully completed a collaboration that involved the identification of compounds that exhibit activity against several novel gene variants, or haplotypes, of the estrogen receptor. Telik has acquired an exclusive right to license this joint intellectual property for further development and intends to seek partnerships with companies that have significant expertise in women's health. Both Telik and Genaissance will share in revenues derived from any licenses. "Genaissance successfully applied its advanced HAP(tm) Technology to discover certain estrogen receptor gene variants that may influence the efficacy and side effect profiles of drugs for estrogen-related diseases such as breast cancer and osteoporosis," said Michael M. Wick, M.D., Ph.D., Telik's chairman and chief executive officer. "By applying our TRAP drug discovery technology, we were able to identify several small molecules that have shown high affinity for certain variants that could enable the development of new drugs that can either target or avoid specific receptor variants for safer and more effective therapy." "Telik's TRAP chemogenomic drug discovery technology is well-suited to lead identification in the post-genomic era of drug discovery," said Gualberto Ruaño, Ph.D., M.D., chief executive officer of Genaissance. "Its speed and efficiency in lead identification are key attributes that contributed to the success of our collaboration." Telik, Inc. of South San Francisco, California, is a biopharmaceutical company working to discover, develop and commercialize small molecule drugs to treat serious diseases for which there is significant demand for new therapies. The company's most advanced development programs are for the treatment of cancer and diabetes. Telik's product candidates were all discovered using its proprietary technology known as TRAP, which enables the rapid and efficient discovery of small molecule drug candidates.
