A new policy paper released on 2 November 2025 sets out the MHRA’s proposals on overhauling and transforming the UK regulation of rare therapies.
The intention is for a “bold new rulebook for rare therapies” to be published in 2026. Rare therapies is defined as medicinal products intended to treat rare diseases, specifically, conditions with a prevalence of no more than 5 in 10,000. The Medicines and Healthcare products Regulatory Agency (MHRA)’s press release on the matter provides the concerning statistic that, while ≈3.5 million people in UK are affected by rare diseases (equivalent to one child in every classroom), and many more if carers are taken into account, only 5% of rare diseases have approved treatment. An intention of the reform is therefore to shorten the time for development of therapies for such conditions from initial discovery through to the stage of delivery to patients.
The MHRA aims to position the UK as a global leader in developing, regulating, and integrating rare therapies into healthcare. This policy paper outlines a new regulatory framework designed to accelerate access to innovative treatments for rare diseases while maintaining safety and evidence standards.
The initiative is supported by the newly formed Rare Disease Consortium, a collaborative effort made up of various different stakeholders including the MHRA, NICE, DHSC, NHS England, as well as patients and their representatives, academia and research institutions and industry.
A draft of the framework is anticipated to be available by Spring 2026, with external review in the first half of the year. A public consultation will also be conducted in 2026.Continue Reading Rewriting the Rulebook: MHRA’s Vision for Rare Disease Therapies
