Abbott and Dharmacon Inc. has announced that a collaboration to develop new therapeutic agents based on a gene silencing technology of RNA interference (RNAi). The research could extend drug discovery efforts for the two companies into disease targets, where traditional discovery technologies have not been successful.
During the collaboration, Abbott and Dharmacon will work to identify therapeutic siRNAs for multiple therapeutic areas, initially focusing on oncology. Dharmacon's industry-leading proprietary siRNA chemistries, its innovative smart selection and smart pool technologies and its specificity-enhancing design modifications will be used to optimize siRNAs for therapeutic use. Abbott will manage the drug discovery and development process and will be responsible for commercialization of products that result from the collaboration.
"Joining forces with RNAi, pioneer Dharmacon to develop drug candidates that harness the clinical potential of this revolutionary technology are very exciting," said Stephen Fesik, Divisional VP, Cancer Research, Abbott. "The collaboration fits our strategy to extend Abbott's portfolio with novel therapies in areas of high unmet need.
By combining our drug discovery and development expertise with Dharmacon's continuing advances in understanding the fundamentals of siRNA-based gene silencing, we will be able to explore targets that everyone knows exist, but have not been able to successfully create drugs to address. The flexibility and selectivity of siRNA therapeutics should provide promising approaches that are not easily achievable with small molecules or antibodies."
"We are very pleased to be working with a therapeutic development partner with the broad experience and proven track record of bringing innovative new drugs to market as we embark on an ambitious collaboration to develop novel drug therapies using RNAi," said William S. Marshall, VP of Technology and Business Development for Fisher Biosciences. "Dharmacon has long been committed to leadership in the RNAi field, and we believe that the major advances we have achieved in the past few years will be especially valuable in our drug development efforts with Abbott."
RNA interference, commonly referred to as RNAi, is a mechanism that cells use for selectively silencing gene expression and decreasing the amount of specific proteins inside the cell. This process is mediated by small, naturally-occurring double-stranded RNA molecules. However, it can be induced by adding chemically-synthesized, short-interfering RNAs (siRNAs) to the cell. siRNAs can be made that silence most cellular genes by altering the RNA sequence to match the corresponding gene sequence. This has exciting therapeutic potential since it provides a new way of targeting known disease-causing genes, including those for which small-molecule drugs have not been found.
