About RxBiologics

RxBiologics is part of the RxCelerate group of companies. RxCelerate, was founded in 2013, with a vision to provide a bespoke high quality outsourced drug discovery and development platform. In 2018, RxCelerate made the decision to collaborate with Jonny Finlay, an experienced biotech antibody engineer, and invest in building from first principles a world-leading biologics antibody discovery platform to generate lead antibodies with the desired drug like properties from the beginning.
