The reforms were developed through a series of stakeholder workshops, seeking the views of a wide range of organisations and individuals from across the clinical research sector, including patient representatives.
A public consultation took place in January to March 2022, to which over 2,000 responses were received, and the Government response was published in March 2023.
The New clinical trials draft legislation (Medicines for Human Use (Clinical Trials) (Amendment) Regulations 2024) was laid in Parliament on 12 December 2024 to:
- address the research sector’s need for a more efficient, streamlined and adaptable regulatory framework for clinical trials.
- make the UK a more attractive place for innovators to conduct important research and to help to get potentially life-changing new treatments to patients and the NHS as quickly as possible.
Here is a link to the statement made in parliament by Baroness Merron on 12 Dec 2024 concerning laying of the Medicines for Human Use (Clinical Trials) (Amendment) Regulations 2024 before Parliament.
The New UK clinical trials regulations (The Medicines for Human Use (Clinical Trials) (Amendment) Regulations 2025) were signed into law on 11 April 2025.
A 12-month roll-out began on 11 April 2025 to deliver the most significant update to UK clinical trials regulation in two decades – with the aim of:1
- strengthening patient safety,
- accelerating approvals,
- enabling innovation and
- helping more people benefit from taking part in vital research.1
The new legislation will take full effect from 10 April 2026 following a 12-month implementation period to ensure readiness, aims to reduce unnecessary administrative burdens on trial sponsors without compromising patient safety.
Post-publication note:
The new clinical trial regulations came into force on 28 April 2026. The date was changed due to a technical issue during the final processing of the Clinical Trial Statutory Instrument (SI) within the digital legislation platform, which meant the SI needed to be re-signed on 28 April 2025.
The reforms will1:
- Put patients and their safety are at the focus of all clinical trials and bring the benefits of clinical trials to everyone.
- Cut duplication and unnecessary delays, while maintaining robust oversight of the safety of trials.
- Create a proportionate and flexible regulatory environment, reducing bureaucracy for lower-risk trials.
- Cement the UK as a destination for international trials.
- Provide a framework that is streamlined, agile and responsive to innovation.
By reducing red tape and simplifying approvals, the new framework supports the Prime Minister’s target to reduce the time from application to first participant from 250 to 150 days. It will speed up research and reduce the time it takes for promising treatments to reach patients, without compromising on safety.1
The Combined Review – a system that lets researchers apply for ethics and regulatory approval in one go – and notification scheme for some clinical trial initial applications and amendments will now be written into law as part of the changes.1
The key reforms to UK CTR proposed in the December 2024 draft legislation have been fully implemented in the final version of the amendment regulations and include:7
- Risk-proportionate Regulation:
- Regulatory requirements now align with the risk level of clinical trials.
- Low-risk trials can receive faster approval through automatic authorisation without comprising patient safety.7
- Streamlined Approval Process:
- A combined review process integrates regulatory and ethics committee approvals, leading to a single UK decision for decision for clinical trials.
- This aims to reduce duplication and unnecessary delays while maintaining robust oversight of trial safety.7
- Enhanced Transparency Requirements:
- New legal obligations mandate the registration of clinical trials in public registry and the publication of trial results within 12 months of the trail’s conclusion.
- This initiative aims to build public trust in research by improving access to information about ongoing studies.7
The following key elements have also been confirmed in the final amendment regulations:7
- Notification Scheme for Low-Risk Trials:
- A notification scheme has been introduced for lower-risk clinical trials, enabling sponsors to notify the MHRA about eligible trials where the risk to participant is similar to standard medical care.
- This streamlined process facilitates faster initiation of these trials without compromising safety.7
- Extended Archiving Period:
- The regulations now require the archiving of trial master files for 25 years, an extension from the previous 5-year requirement.
- This change ensures long-term accessibility to trial data for future reference and analysis.7
- Sunset Period for Trials Approvals:
- Clinical trial approvals will now lapse after a proposed sunset period of two years if no participants have been enrolled.
- This measure encourages timely initiation of trials and optimises resources allocation.7

| Currently used term(s) | New term(s) or definitions as per the new regulations | Notes |
|---|---|---|
| Amendment | Modification From 28 April 2026, modifications will be categorised as: i) ‘substantial modifications’, ii) ‘modification of an important detail’ or iii) ‘minor modifications’. | The term ‘modification’ is already used by the EU countries to describe changes to clinical trials of investigational medicinal products (CTIMPs). This change will make sure there is better alignment between the UK and the international research community. |
| Non-investigational medicinal product Notifiable trial and Public registry. | The new regulations introduce these new definitions | |
| Authorised health care professional | Healthcare professional | The new regulations say that chief investigators and investigators should be a health care professional as defined in the amended legislation. |
| Subject | Participant | Terminology update in line with the new regulations |
| Trial site | Trial location | Terminology update in line with the new regulations |
Yes, alongside the regulations, the MHRA and HRA has published guidance to embed meaningful public involvement in clinical trials and increase the diversity of people taking part in research trials. This will ensure that research findings can improve everyone’s care, helping address health inequalities.

As per regulation 20 of the Clinical Trials Regulations, a clinical trial approval may be modified by:
- the trial’s sponsor,
- the licensing authority, or the ethics committee.

What are the categories of modifications to a clinical trials authorisation approval
Modifications to a clinical trial approval can be categorised into:
Substantial modifications categorised as Route A or Route B
i) Route A substantial modifications
- These are likely to have a substantial impact on the safety or rights of the participants or on the reliability or robustness of the data generated in the trial
- Approval to make substantial modifications must be received from the licensing authority and ethics committee before implementation.
- The exception to this is for substantial modifications that relate to urgent safety measures.
- When considering implementing substantial modifications, sponsors should assess whether such modifications alter the original clinical trial approval to the extent that it should be considered a new clinical trial.
- If this is the case, a new application for clinical trial approval should be submitted.
ii) Route B substantial modifications
- These are defined in regulation 11B of the Clinical Trial Regulations and the examples section of this guidance.
- Note that the ethics committee does not provide automatic approval for Route B substantial modifications
Modifications of an important detail
- These do not significantly impact the safety or rights of the participants but the authorities need to be aware of them for administrative or oversight purposes.
- Instructions for notifying the authorities about a modification of an important detail are provided on completion of the modification tool.
Minor modifications
- These may be implemented at any time and without informing the licensing authority or ethics committee at the point of implementation (however, other approvals may be required, which can be determined using the modification tool).
- The sponsor must keep records of any modifications implemented and, if requested, make them available to the licensing authority or ethics committee.
Source: MHRA
It is the sponsor’s responsibility to determine the modification type, using a risk-based approach, whether a modification is substantial, minor or a modification of an important detail.
Source: MHRA
The MHRA is also expanding its current risk proportionate approach to include the review of modifications to approved clinical trial applications.
- Once implemented under the new regulations, substantial modifications which meet pre-defined criteria will be eligible for automatic approval from the MHRA through the Route B substantial modification process.
- This process will need to be followed by everyone submitting an eligible modification to a clinical trial.
- Draft guidance supporting the Medicines for Human Use (Clinical Trials) (Amendment) Regulations 2025 is available in this post and in more detail on the Clinical Trials Hub.
- The section on modifying a clinical trial covers the Route B substantial modifications criteria.
Source: MHRA
To ensure a smooth transition into the new Clinical Trials Regulations, the MHRA will be testing the Route B substantial modification process over the coming months and invite you to get involved.
The MHRA is opening a pilot for Route B substantial modifications from 1 October 2025 until 31 March 2026, and encourages you to sign up to take part. More information is available on this MHRA page.
By joining the pilot, you will gain early insight into how the new process works and help the MHRA shape it, so it’s ready to support the new regulations from 28 April 2026.
