Pierre Fabre Laboratories and RedRidge Bio (“RedRidge”) today announced an exclusive R&D collaboration and license agreement to identify and develop biparatopic antibody (BPA) drug candidates against multiple targets. In line with Pierre Fabre Laboratories’ innovation strategy, the partnership’s therapeutic focus will be on precision oncology as well as dermatology and rare diseases.  
Under the terms of the agreement, RedRidge will provide its capabilities to engineer, screen and characterize BPAs against an undisclosed portfolio of jointly nominated targets, while Pierre Fabre Laboratories will provide their drug development expertise to help drive two co-development programs through clinical development. RedRidge will hold exclusive commercial rights in the United States, Canada, and Japan for both programs, while Pierre Fabre Laboratories will hold exclusive rest-of-world rights. In addition, Pierre Fabre Laboratories will hold exclusive worldwide rights for a third program after a hand-off by RedRidge at a preclinical stage. 

Financial terms of the agreement are not disclosed but include investment participation by Pierre Fabre Laboratories in RedRidge’s Series A financing that will be announced separately, as well as upfront, milestone and future sales royalty payments in addition to funded research payments for Pierre Fabre Laboratories’ worldwide program. RedRidge and Pierre Fabre Laboratories will share R&D costs for the co-development programs.

About RedRidge Bio

RedRidge Bio was incubated by Versant Ventures and the firm’s Ridgeline Discovery Engine in Basel Switzerland.  RedRidge is an R&D company focused on the discovery and development of biparatopic antibodies for best-in-class efficacy. Biparatopic antibodies are multispecific therapeutic proteins that engage distinct epitopes on the same molecular target, which can offer myriad benefits compared to conventional antibodies, including superior functional antagonism, more efficient internalization, and fit-for-purpose agonism.  With its leading platform that systematically elucidates desired candidates by leveraging high-throughput and big data, the company is developing a pipeline of therapeutic candidates in oncology and autoimmunity on both a fully proprietary basis and with its co-development partner, Pierre Fabre Laboratories.
