Diogenx SAS raised €27.5 million (US$30.4 million) in a series A round to move a novel therapy for type 1 diabetes into clinical development. The Marseille, France-based company is building on the research of co-founder Patrick Collombat, an expert in beta-cell regeneration, who is based at the Insitute of Biology Valrose and the University Côte d’Azur, in Nice. Its lead drug candidate comprises a recombinant R-spondin protein, which acts on the Wnt/beta-catenin signal pathway to boost replication of endogenous functioning beta-cells.
