Introduction

Assays used in clinical trials vary widely in complexity and regulatory status.. They may be fully developed and marketed as in vitro diagnostic medical devices (IVDs), including companion diagnostics (CDx), that clearly fall within the scope of the EU In Vitro Diagnostic Regulation (IVDR) and/or the UK Medical Devices Regulations 2002 (UK MDR). Alternatively, they may be bespoke assays created specifically for use in a given clinical trial or in connection with an investigational medicinal product (IMP).

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 February and early March 2026 from the the United Kingdom, and European Union.

February 2026 saw a period of substantial regulatory activity across both the UK and EU, particularly in relation to AI governance, medical technologies, and data protection. In the UK, the policy landscape continued to evolve with initiatives affecting the regulation of medical devices, clinical research, and AI deployment. Key developments included the Medicines and Healthcare products Regulatory Agency’s (MHRA) consultation on the indefinite recognition of CE-marked medical devices, record levels of medical device testing, and the Prescription Medicines Code of Practice Authority’s (PMCPA) revised guidance on the use of social media. AI remained a major focus in the UK, with the UK government’s response to the consultation on the AI Management Essentials tool, increased industry involvement in the UK AI Security Institute’s alignment program, and feedback relating to governmental research on AI adoption across UK businesses. Additional international collaboration efforts included UK engagement at the India AI Impact Summit and an expanded science and technology partnership with Japan, as well as the launch of the first-ever AI Strategy for UK Research and Innovation.

On 16 December 2025, the European Commission published its Proposal for a Regulation establishing a framework of measures for strengthening the EU’s biotechnology and biomanufacturing sectors, particularly in the area of health (the “European Biotech Act” or the “Proposal”). The Proposal is ambitious in scope: it amends several major pieces of EU health legislation, including the Clinical Trials Regulation (“CTR”), the Veterinary Medicines Regulation, the Food Law Regulation and the Substances of Human Origin Regulation (“SoHO”), while also introducing a new framework for EU strategic projects, AI-enabled biotechnology, and biodefence.

On 10 March 2026, the European Data Protection Board (“EDPB”) and the European Data Protection Supervisor (“EDPS”) adopted Joint Opinion 3/2026 on the Proposal (the “Joint Opinion”). While broadly supportive of the Proposal’s objectives, the EDPB and EDPS identified a number of significant data protection concerns, and issued recommendations. Although not legally binding, the Joint Opinion carries significant weight as it reflects the views of the EU’s primary data protection authorities and will directly shape the legislative debate ahead.

In this blog we examine the key data protection implications of the Proposal and the Joint Opinion for pharma and life sciences companies.

Growth in UK clinical trials

The UK’s ambition to strengthen its position as a leading destination for global clinical research is beginning to show results. According to a recent MHRA publication, clinical trial applications submitted between January and November 2025 were 9% higher than during the same period in 2024, with particularly notable increases in:

  • Trials in healthy volunteers (+16%)
  • First‑in‑human studies (+5%)
  • Trials being run in the UK for the first time (+7%)

The publication notes that “growth was strongest in early and innovative research, where speed and expert regulatory support can make or break decisions on where companies invest.”

On 2 July, 2025, the European Commission published its EU Life Sciences Strategy (the ‘Strategy’), setting out a roadmap to position the European Union (EU) as a global leader in life sciences by 2030.

For pharmaceutical, MedTech, and biotech companies, the Strategy may, at least in theory, represent a positive shift towards a more innovation-driven environment for research and development (R&D) and market access in life sciences. This will, however, depend, to a great extent, on the practical impact and implementation of the other policy and legislative initiatives in the EU (e.g., the reform of the EU pharmaceutical legislation (see our latest blog), Biotech Act, Critical Medicines Act (see our blog)).

The Strategy presents concrete EU level actions to address long-standing challenges in life sciences in the EU, such as regulatory fragmentation across EU Member States, as well as the barriers to multi-country clinical trials and to the market access of advanced therapies and novel technologies.

A new Life Science Coordination Group within the European Commission will oversee the implementation of the Strategy and ensure that EU policies are consistent and supportive of innovation.

This blog highlights key elements of the Strategy of relevance to pharmaceutical, MedTech, and biotech companies.

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.

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 28 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.”

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.

On 21 October 2024, the Medicines and Healthcare products Regulatory Agency (MHRA) announced that the UK will be the first country in the world to introduce a tailored framework for the manufacture of innovative medicines at or close to the location where a patient receives care.

A new statutory instrument was laid before the UK parliament to amend the Human Medicines Regulations 2012 and the Medicines for Human Use (Clinical Trials) Regulations 2004, to provide a new regulatory framework to support the manufacture and supply of these innovative products. This includes:

  1. products with a very short shelf life and highly personalised medicines that mean they have to be manufactured close to the place where they are administered; known as Point of Care, or POC, products. This often applies to advanced therapy medicinal products (ATMPs), but could also be technologies such as 3D printing.
  2. products that are manufactured in a self-contained modular unit, to enable deployment from that site to other locations; known as Module Manufacture, or MM, products.

This new framework follows a consultation in 2021, discussed in a previous blog post. The consultation received overwhelming support, and 91% of responders agreed with the need for a new regulatory framework. At present, there is no specific framework that covers decentralised manufacturing of medicines in the UK, but as products become more innovative, and more personalised to the patient, the need for change has increased. At present, any on-site manufacturing has to rely on the hospital having obtained the necessary licences and having put in place the required quality, safety and traceability standards under the general framework. This leads to practical – and contractual – difficulties between the company and hospital sites.

The new framework seeks to provide the necessary regulatory oversight to ensure that POC and MM products have appropriate quality, safety, and efficacy attributes, whilst allowing increasing numbers of patients to benefit from these innovative products. According to the MHRA, the proposed regulation ensures that POC and MM products can be more easily made in or near a hospital setting and can get to the patients who need them safely and more quickly.
