The UK’s Medicines and Healthcare products Regulatory Agency (“MHRA”) is seeking industry feedback on its new draft guideline on individual messenger ribonucleic acid (“mRNA”) cancer immunotherapies (the “Draft Guidance”).  Building on the success of mRNA vaccine technology in response to the Covid-19 pandemic, the technology is now being adapted to target diseases such as cancer.  The MHRA aims to provide a streamlined robust regulatory framework for the approval of such personalised mRNA-based cancer vaccines without compromising safety.

The Draft Guidance covers the regulatory classification of these novel cancer treatments, product design and manufacture, non-clinical and clinical development, pharmacovigilance and the distribution of information to the wider public.  Notably, the MHRA explicitly acknowledges that the regulatory and scientific principles discussed in the Draft Guidance could broadly apply to other disease indications or technologies that could benefit from personalisation or individualisation.  Therefore, industry should be aware that the scope of the Draft Guidance may be extended in the future beyond mRNA cancer immunotherapies that use lipid nanoparticle delivery systems to other delivery systems and disease areas.  Manufacturers, developers, patient organisations and other stakeholders have until 31 March 2025 to comment on the Draft Guidance.

We explore some of the interesting regulatory considerations arising from the Draft Guidance below.

Regulatory Classification

The classification of a medicinal product is key to determining what requirements and guidelines apply to the development, manufacture and delivery of that product.  For example, advanced therapy medicinal products (“ATMPs”) have specific Good Manufacturing Practice (“GMP”) requirements (see e.g., ‘Guidelines on Good Manufacturing Practice specific to Advanced Therapy Medicinal Products’), strict traceability requirements and additional pharmacovigilance requirements.

Currently, individual mRNA cancer immunotherapies are classified under the Human Medicines Regulations 2012 (as amended) (“HMRs”) as ATMPs and are sub-classified as gene therapies.  However, current mRNA therapies do not fit neatly under the ‘gene therapy’ umbrella because, unlike conventional gene therapies, which are designed to edit a person’s genome to treat or cure a disease, mRNA therapies do not involve integration into the host genome.

The Draft Guidance reveals that “a new ATMP sub-classification for nucleic acids that do not edit the patient’s genome is being considered.”  A practical advantage of a new sub-classification would be the opportunity to create bespoke and risk proportionate requirements and guidelines for mRNA therapies.  This would avoid overburdensome risk mitigations for these products as compared to similar products such as COVID-19 vaccines.

The Draft Guidance also predicts that mRNA therapies could be chemically synthesised (i.e., not manufactured by biotechnology).  Such therapies would fall outside the scope of the current definition of a gene therapy as they would not be a biological product.  The MHRA is considering the classification of relevant chemically synthesised mRNA therapies as ATMPs.Continue Reading MHRA Consultation on Individualised mRNA Cancer Immunotherapies – Unique opportunity for a streamlined risk based regulatory framework?

Last month we provided an update on the UK Government’s draft post-market surveillance statutory instrument (“PMS SI”) and the UK Medicines and Healthcare products Regulatory Agency’s (“MHRA’s”) intention to run a further public consultation on proposed changes to pre-market medical device regulation under an upcoming statutory instrument (“Pre-Market SI”).

On 14 November 2024, the MHRA launched a consultation on proposed pre-market regulatory changes for medical devices and in vitro diagnostic (“IVD”) devices (the “Consultation”).  The MHRA intends to incorporate the feedback from the Consultation in drafting the Pre-Market SI.

The Consultation, which is open until 5 January 2025, addresses four areas of the future regulatory framework for medical devices in Great Britain (“GB”):

  1. International Reliance Scheme
  2. UK Conformity Assessment (“UKCA”) Marking
  3. In Vitro Diagnostic Devices
  4. Assimilated EU Law

It builds on the MHRA’s previous consultation in November 2021 (see our update here) and the responses to that consultation.

In the Ministerial Foreword to the Consultation, the Government makes clear that its reforms to the regulatory framework for medical devices in GB are focused on improving “timely access to high-quality healthcare”.  However, the Government recognises that this aim must be balanced with ensuring confidence in the safety and effectiveness of “groundbreaking medical devices”.

We discuss the four areas of the Consultation below.Continue Reading MHRA Consults on New UK Pre-Market Medical Device Measures

On 21 October 2024, the UK Government laid the draft Post-market Surveillance statutory instrument (“PMS SI”) before Parliament (see the UK Medicines and Healthcare products Regulatory Agency’s (“MHRA’s”) press release here).  Once implemented, the PMS SI will further amend the UK’s Medical Devices Regulations 2002 (“UK MDRs”) by introducing new vigilance requirements for medical devices already on the Great Britain (“GB”) market.  The proposed updates to the UK MDRs seek to bring it into greater alignment with the EU’s Medical Devices Regulation 2017/745 (“EU MDR”) and In Vitro Diagnostic Medical Devices Regulation 2017/746 (“EU IVDR”), whilst also taking advantage of certain opportunities resulting from the UK’s withdrawal from the EU to build on and diverge from this legislation.

The long-awaited draft PMS SI follows the Government’s response in June 2022 to the MHRA’s 2021 consultation on the future regulation of medical devices in the UK.  In January 2024, the Government published its ‘Roadmap towards the future regulatory framework for medical devices’, which set out the intended timeframe for delivery of the future regulatory framework. 

Since the Government’s response in June 2022, reform of the regulatory framework for medical devices has suffered several delays as a result of various factors, including (i) the extension of the transitional periods under the EU MDR and EU IVDR (see our update here) and knock-on impact on UK strategy, (ii) the UK proposals to adopt a new international recognition procedure for device approvals (see our update here), and (iii) a change of government.

The draft PMS SI represents the new Government’s first step in updating the UK’s legal framework for medical devices.  Subject to the PMS SI’s passage through Parliament, the final version is expected to come into force in the summer of 2025.

What are the Key Changes?

Post-market surveillance (“PMS”) requires manufacturers to monitor the safety of a medical device after it has been released on the market, and, where necessary, take appropriate action to prevent or reduce the risk of an identified safety issue.  The current UK MDRs contain high-level provisions relating to PMS, which are supplemented by MHRA guidance (which is based on European Commission MEDDEV guidance applicable to the now repealed EU Medical Devices Directive 93/42/EEC).

The Government hopes the draft PMS SI will improve patient safety by introducing more stringent and clearer PMS requirements for both CE marked devices and UKCA marked devices that are placed on the market or put into service in GB.  To that end, the draft PMS SI introduces the following:Continue Reading UK’s Medical Device Post-market Surveillance Statutory Instrument Laid Before Parliament – What are the Key Changes for Medical Device Regulation?
