Update on commercial pre-launch activities for Infacort

Appoints industry-leading outsourced commercial services providers to support potential product launch in late 2017

Diurnal Group plc (AIM: DNL), the specialty pharmaceutical company targeting patient needs in chronic endocrine (hormonal) diseases, announces significant progress in its commercial pre-launch activities following its first market authorisation submission for Infacort to the European Medicines Agency (EMA) in December 2016, for which the Company anticipates market authorisation in late 2017.

As previously stated, Diurnal's ambition is to market Infacort® itself in major European territories, thereby retaining the full commercial value of the product. Consistent with this strategy, Diurnal has signed a service agreement with Ashfield Healthcare ('Ashfield'), part of UDG Healthcare plc (LSE: UDG), to support the Company in building sales and medical infrastructure in major European territories. Ashfield is a respected global contract sales organisation that will focus in the next 12 months on establishing a Europe wide network of medical liaison staff to prepare the Company for the anticipated launch of Infacort® in 2018.

In addition, Diurnal has also signed an agreement with Sharp Packaging Services ('Sharp'), a global leader in contract packaging for the pharmaceutical and biotechnology industries, which is also part of UDG Healthcare, to bring expertise to ensure our Infacort® supply chain is managed by an internationally recognised expert business.

Together, these agreements provide the foundation for Diurnal's supply chain to deliver the commercial product to Europe and other territories worldwide.

Dr Martin Whitaker, CEO of Diurnal, commented:

'Following the submission of our regulatory application for Infacort to the EMA and its subsequent validation, we are focussed on pre-launch activities for this product in Europe. We are confident that the agreements announced today with Ashfield and Sharp, both leading providers of outsourced commercialisation services to the pharmaceutical industry, will help ensure the prompt and effective market introduction of Infacort following its anticipated approval in Europe, another key step in realising our ambition of becoming the world's leading specialty pharma company in endocrinology.'

Notes to Editors

About Adrenal Insufficiency

Adrenal Insufficiency (AI) is a condition characterised by deficiency in cortisol, an essential hormone in regulating metabolism and the response to stress. AI has been identified as a rare disease in Europe where there are estimated to be approximately 4,000 sufferers younger than the age of six. Currently there are no licensed hydrocortisone preparations in Europe specifically designed to treat these young patients. These children are often administered compounded adult tablets or other unlicensed products. Poor control of disease can result in precocious puberty in young children, virilisation in girls and chronic fatigue leading to a poor quality of life in adulthood resulting in increased morbidity and mortality.

About Infacort

Infacort represents the first preparation of hydrocortisone specifically designed for use in children suffering from AI. It is a patented, immediate-release, oral, paediatric formulation of hydrocortisone that allows for age-appropriate dosing in children. This therapeutic approach has the potential to help young patients less than six year of age suffering from diseases due to cortisol deficiency including adrenal insufficiency and congenital adrenal hyperplasia. AI requires life-long treatment and Diurnal's novel approach to product development has the potential to significantly improve these young patients' lives. The European Medicines Agency has already approved a Paediatric Investigation Plan (EMEA-001283-PIP01-12) for Infacort, which sets out the regulatory pathway to market authorisation via the Paediatric Use Marketing Authorisation (PUMA) route.
