STX is a commercial-stage company delivering specialty products that address patients’ unmet medical needs, with an initial focus on treating iron deficiency (ID). Feraccru®/Accrufer® has been approved by the regulators in both Europe and the US. For various reasons, STX has been unable to secure a commercial partner for Accrufer in the US. Consequently, the board is now considering an STX-led launch option, thereby retaining all the US profits. Financial modelling shows the logic of this option, but it would necessitate financing the working capital requirements covering the next two years in the region of £25m-£30m.
