THX Pharma, the trade name of Theranexus, is a biotechnology company based in Lyon, Auvergne-Rhône-Alpes, focused on therapies for rare neurological diseases. Its lead candidate TX01 targets Niemann-Pick type C disease and Gaucher disease and is planned for commercialization in Europe with Exeltis and in the United States, Canada, and Australia. A second program, Batten-1, targets juvenile Batten disease and could become the first approved therapy for that condition, while the company maintains a platform based on antisense oligonucleotides developed in collaboration with research laboratories to address rare neurological disorders. The firm operates in the biotech sector with a strategy that includes partnerships and licensing to bring treatments to regional markets. In early 2026, Theranexus announced an asset sale transferring Batten-1 worldwide and TX01 rights in the United States and Canada to Biocodex, and the company is listed on Euronext Growth Paris.
