Company Profile

Founded in 2004, Diurnal Group plc is a European, UK-headquartered specialty pharmaceutical company dedicated to developing products for the life-long treatment of chronic endocrine conditions.

We are committed to addressing major unmet clinical and patient needs in hormone replacement, initially by developing and marketing products for the rare diseases Congenital Adrenal Hyperplasia (CAH) and Adrenal Insufficiency (AI).

Through our extensive knowledge, experience and persistence we have created a specialised pipeline of product opportunities for the treatment of hypogonadism, hypothyroidism and other endocrine disorders.

Diurnal’s expertise and innovative research activities focus on circadian-based endocrinology (mimicking the body’s natural hormone levels), which has yielded novel product candidates being trialled in patients prior to the submission of a marketing authorisation application.

Diurnal Group plc (Company Number: 09846650) is registered in England & Wales. Registered office: Cardiff Medicentre, Heath Park, Cardiff CF14 4UJ, UK.
