Established in 2004, Avivia is a specialized pharmaceutical development company engaged in CRO service activities, drug repositioning, repurposing and reformulation. Over the past ten years, the company has built a solid reputation recognized for its R&D flexibility and ‘out-of-the-box’ approach towards complex and challenging analytical and pharmaceutical development projects. Today, we are the preferred partner for many big pharma, specialty pharma, generic drug companies and smaller drug development firms. We operate a hybrid business model combining CRO service activities (both full development programs as well as stand-alone services) with internal product programs aimed at the development of value-added products. Our offices and state-of-the-art laboratories are located in Nijmegen, The Netherlands, in close proximity to the German and Belgian borders.
