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

Welcome to the latest installment of Arnold & Porter’s Virtual and Digital Health Digest. This digest covers key virtual and digital health regulatory and public policy developments during September and early October 2025 from the the United Kingdom, and European Union.

This month, the EU and UK have been actively processing the future of AI development and regulation in life sciences and health care through a combination of legislative initiatives, opportunities for stakeholder engagement, and investment in infrastructure. In the EU, the European Commission has published draft guidance on reporting serious AI incidents under the AI Act, and the European Medicines Agency has initiated a stakeholder survey to define AI priorities in medicines regulation. In the UK, the UK government has announced a National Commission on the Regulation of AI in Healthcare and a new AIR-SP cloud platform. These developments signal a shift from theoretical regulation to practical implementation. There have also been two important decisions from the Court of Justice of the European Union refining the legal boundaries of digital health services and data protection.Continue Reading Virtual and Digital Health Digest – October 2025

On 8 September 2025, the European Commission published a call for evidence on “the targeted revision of the EU rules for medical devices and in vitro diagnostics”. This is part of the Commission’s on-going “targeted evaluation” of the Medical Devices Regulation (MDR) and the In Vitro Diagnostics Regulation (IVDR), with the aim of identifying methods to tackle critical issues experienced throughout the industry caused by the regulations.Continue Reading European Commission’s call for evidence on the revision of the MDR/IVDR

On 31 July 2025, the UK government published a statement of policy intent, setting out its initial thinking on an Early Access Service (EAS) for innovative medical devices. The intention is for this to first focus on innovative diagnostic devices, particularly those supporting the NHS’s most urgent needs and financial sustainability in the NHS.  It is hoped this will lead to quick market access of such devices, by addressing challenges associated with generating sufficient evidence to obtain regulatory approval.Continue Reading UK proposes Early Access Service for innovative medical devices

The UK government has published its response to the recent consultation on the UK Medical Devices Regulations. As highlighted throughout the process to date, the focus is on improving regulatory scrutiny and oversight of medical devices and IVDs in the UK. Changes are aimed at closer alignment with international best practice and to ensure that Great Britain has risk proportionate regulations. Changes are not intended to introduce the EU Medical Devices Regulations into UK law, although there are of course similarities, which has been welcomed by those responding to the consultation.

There were four key areas under consultation: (1) International reliance, (2) UKCA marking, (3) IVD devices, and (4) Assimilated EU law. We have set out a summary on each of these below.Continue Reading UK Medical Devices Regulations: further changes afoot

On 13 June 2025, the European Commission launched the first phase of a pilot project under its COMBINE programme (the pilot project), aiming to streamline the authorisation process for combined studies involving both clinical trials of medicinal products and performance studies of in vitro diagnostic medical devices (IVD) (referred to as combined studies below).

The pilot project represents a significant step towards addressing the complex and fragmented regulatory landscape that sponsors currently face when submitting applications for combined studies across multiple EU countries. Although its practical effectiveness remains to be seen, the pilot project represents a positive development that should facilitate the approval of combined studies in the EU.

The pilot project is the first initiative under the COMBINE programme, with additional projects planned to launch in the coming years.Continue Reading European Commission launches COMBINE pilot to streamline approval of studies involving medicinal products and in vitro diagnostic medical devices

The current EU regulatory landscape for biotechnology is widely viewed as insufficient to be able to exploit the full potential of such technologies. Regulatory hurdles exist at EU and Member State level, and this is thought to have driven investment into other regions.

To help tackle this problem, the introduction of a new EU Biotech Act (the Act) has been proposed by the Commission to encourage innovation in areas such as health technology assessment and clinical trials. A simpler regulatory landscape, with no reduction to safety standards, will be a central aim of the Act.

However, it was announced on 20 March 2025 that the Act has been delayed until the third quarter of 2026 (initially due in the last quarter of 2025). As such, it remains to be seen what shape the Act will take, including whether any changes will be limited to setting out general guidelines, or whether it will take the form of a binding legal instrument, imposing specific measures to which Member States and EU institutions must adhere. Various studies and papers have been developed following the announcement of the proposed Act, and it is hoped that as these are finalised, they will provide further insight into what we can expect.Continue Reading EU Biotech Act– what we know so far

On 11 April 2025, the MHRA announced  that the much anticipated changes to the clinical trial rules in the UK, the Medicines for Human Use (Clinical Trials) (Amendment) Regulations 2024 (the new Regulations), have been signed into law.

In January, we posted a detailed blog on the upcoming changes to the UK law governing clinical trials, noting that this had been described as the “biggest overhaul of the clinical trial regulations in 20 years”, and is intended to cement the UK as a world-class destination for conducting international clinical trials, to “support [a] more streamlined and flexible regulation of clinical trials, removing unnecessary administrative burdens on trial sponsors, whilst protecting the interests of trial participants.”

The new Regulations will come into effect on 10 April 2026, following a 12 month roll out period. The MHRA states in its announcement that it is “committed to implementing a flexible and risk-proportionate regulation of clinical trials, which accelerates patient access to potentially life-saving medicines without compromising safety.”Continue Reading Recent updates on reform of UK clinical trial landscape

We recently published this Advisory for our US clients, but thought it may be a useful reminder for UK and EU teams given the number of updates in this area.

We are sure that you are aware that the European Union (EU) medical devices framework has been subject to significant changes over recent years. However, implementation of the new rules has been problematic since the beginning, as both the industry and the EU institutions, national authorities, and notified bodies have found it difficult to adapt to the stricter and demanding new legal requirements. There are ongoing delays in companies obtaining CE marks under the new regime, criticism that the rules are stifling innovation, and concerns about the impact on patients.

Given the calls for change, criticism, and ongoing consultations, this Advisory sets out the current status of developments and what is important to know when seeking to do business in the EU.Continue Reading EU Medical Devices Legislation: What You Need To Know Given Latest Developments and Ongoing Challenges

2025 promises to be a year of further advancements in the UK’s life sciences sector and one important area of on-going development is the regulation of clinical trials.

After some delay, the much anticipated Medicines for Human Use (Clinical Trials) (Amendment) Regulations 2024 (the new Regulations) were laid before Parliament on 12 December 2024, intended to amend the current UK framework governing clinical trials. This has been described as the “biggest overhaul of the clinical trial regulations in 20 years”, and is intended to cement the UK as a worldclass destination for conducting international clinical trials, to “support [a] more streamlined and flexible regulation of clinical trials, removing unnecessary administrative burdens on trial sponsors, whilst protecting the interests of trial participants.”

Key changes proposed by the new Regulations are discussed below. While certain regulatory requirements will be set out in the legislation, the aim is to move away from a “one-size-fits-all” approach, allowing for a more proactive response to innovation. This is in line with the new streamlined notification scheme for lowest risk clinical trials, which the MHRA introduced in October 2023, as discussed in our previous blog post. As such, the new Regulations have been described as “as future-proof as possible and […] responsive to different types of trials and innovative ways of carrying out trials.”

The new Regulation will be debated in Parliament in early 2025 and, after a 12 month implementation period, the aim is for the new Regulations to come into force in early 2026. In addition, guidance, which is already under development, will be used for specific details, rather than the new Regulations being too granular and prescriptive. The aim is for the guidance to become ‘live’ in January 2026, to coincide with the new Regulations.  Continue Reading New Year Update: incoming changes to UK regulation of clinical trials
