The MHRA’s proposed rare disease therapies regulatory framework (“the Proposed Framework”) represents an ambitious attempt to redesign medicines regulation around the realities of rare disease development.

On 21 May 2026, the MHRA launched its consultation on the Proposed Framework, representing a significant step in the UK’s ambition to become a global leader in the development of therapies for rare diseases.

The initiative reflects the scale of unmet need: around 1 in 17 people will be affected by a rare disease during their lifetime, equating to over 3.5 million people in the UK, yet only around 5% of rare diseases have an approved treatment.

The consultation acknowledges that traditional regulatory approaches, designed for common diseases with large patient populations and well‑established trial paradigms, are often unsuitable for rare disease therapies.  Against this backdrop, the Proposed Framework aims to enable earlier patient access to promising therapies, reduce development burden, and incentivise innovation, while maintaining the UK’s standards of safety, quality and efficacy.

The MHRA requests responses from industry, patient organisations and other stakeholders. The consultation closes on 30 July 2026.

On 22 March 2018, the European General Court handed down its judgment in Case T-80/16 Shire Pharmaceuticals Ireland v EMA.  Shire had sought annulment of the EMA’s decision refusing to validate its 2015 application for designation of its medicinal product Indursulfase-IT as an orphan medicinal product for the treatment of Hunter Syndrome. This decision is particularly important for innovator companies who invest in R&D for rare diseases, and will likely have an impact on incentivizing this type of research.

Background

In 2001, a Shire product containing the active substance idursulfase was designated as an orphan medicinal product for the treatment of Hunter Syndrome. This was followed in 2007 by the grant of a marketing authorisation for the medicinal product Elaprase, containing the active substance idursulfase, and administered as a solution for intravenous infusion. In parallel, Shire started developing another medicinal product containing the same active substance. However this product, Idursulfase-IT, could be delivered intrathecally, whereas Elaprase did not cross the blood-brain barrier. Intrathecal administration of the new product allowed treatment of cognitive disorders associated with a severe form of Hunter Syndrome.Continue Reading Shire v EMA: European General Court provides clarification for designation of orphan medicinal products
