Diurnal is a clinical stage specialty pharmaceutical company focused on diseases of the endocrine system. Its two lead candidates are targeted at rare diseases with unmet medical need, with the aim of building a long-term ‘Adrenal Franchise’. Following successful completion of a Phase III trial, Infacort has been submitted to the European regulator for final approval. Meanwhile, management is establishing the appropriate commercial infrastructure in readiness for launch of Infacort and Chronocort in 2018 and 2020, respectively. Diurnal is also in the process of expanding its portfolio of products in the endocrine area.

• Strategy: Diurnal’s strategic goal is to create a valuable ‘Adrenal Franchise’ that can treat patients with chronic cortisol deficiency diseases from birth through to old age. Once Infacort and Chronocort are established in EU and the US, the long-term vision is to expand the product offering to other related conditions.
• Results: Reported operating losses of -£12.1m (-£7.0m) largely reflect the increased investment in R&D. This fell through the cashflow statement leaving the company with net cash at the end of June of £16.4m, which was ahead of forecasts (£13.2m).
• Commercialisation plans: Ahead of regulatory approval by the EMA for Infacort, management has started to establish the relevant commercial infrastructure with the appointment of key global marketing support in Europe and Israel. Diurnal will utilise this infrastructure for subsequent products.
• Risks: There is a risk with all drugs in development that they might fail clinical trials or not be approved by the regulators. However, Diurnal is unusually low risk because its products are formulation variants of well-established drugs. Also, assessment of the Infacort registration dossier by the EMA is well advanced.
• Investment summary: Diurnal is focusing on diseases of the endocrine system. Infacort, a cortisol replacement therapy designed for children and babies, is the first product Diurnal will bring to the market. It will be followed by Chronocort for adults. The cortisol replacement market is for conditions that need life-long treatments, and has a potential value of $3.5bn.
