The United Kingdom's exit from the European Union created unprecedented regulatory challenges for its medicines approval landscape. In response, the Medicines and Healthcare products Regulatory Agency (MHRA) pioneered a revolutionary framework—the International Recognition Procedure (IRP)—implemented on January 1, 2024. This innovative procedure replaces the EC Decision Reliance Procedure (ECDRP) and Mutual Recognition/Decentralised Reliance Procedure (MRDCRP), establishing the UK as a global regulatory partner while accelerating patient access to critical therapies 14. By leveraging approvals from trusted international regulators, the IRP enables MHRA to conduct targeted assessments that reduce duplication, conserve resources, and bring life-saving medicines to UK patients in record time—often shaving months or even years off traditional approval timelines 39.
The IRP is a reliance-based pathway allowing MHRA to recognize prior approvals from designated "Reference Regulators" (RRs) when authorizing medicines for the UK market. To qualify, products must be the "same product"—defined as having identical qualitative/quantitative composition (active substances and excipients), identical pharmaceutical form, and originating from the same company or licensee 1. This procedure covers most marketing authorization applications (MAAs), including:
New chemical/biological substances (Regulation 50)
Generic, hybrid, and biosimilar applications (Regulations 51-53B)
New fixed combination products (Regulation 55) 14
Excluded categories include traditional herbal registrations, homeopathic products, and bibliographic applications (Regulation 54), which retain separate national review pathways 1.
The IRP recognizes approvals from regulators demonstrating rigorous scientific standards and robust oversight frameworks. The current RR list includes:
Table: MHRA's Recognized Reference Regulators
| Country/Jurisdiction | Regulatory Authority | |
|---|---|---|
| Australia | Therapeutic Goods Administration (TGA) | |
| Canada | Health Canada | |
| Switzerland | SwissMedic | |
| Singapore | Health Sciences Authority (HSA) | |
| Japan | Pharmaceuticals and Medical Devices Agency (PMDA) | |
| United States | Food and Drug Administration (FDA) | |
| European Union/EEA | European Medicines Agency (EMA) and EU Member State Competent Authorities | 13 |
Notably, approvals through the Access Consortium (even without MHRA participation) qualify if one consortium member is designated as the RR 1.
Designed for recent approvals, Recognition A offers a streamlined 60-calendar-day timetable (from validation) with no clock stops. Key eligibility requirements:
RR approval granted within previous 2 years
Identical manufacturing process to RR-approved product
Evidence of GMP compliance at submission 13
This route suits products without complex risk profiles or manufacturing changes. However, if major objections arise during assessment, MHRA may convert the application to Recognition B 1.
For products with greater complexity or older approvals, Recognition B extends the timeline to 110 calendar days to accommodate deeper assessment. Eligibility includes:
RR approval within previous 10 years (exceptions possible)
Any of 24 specified criteria, such as:
Conditional/exceptional approvals
New manufacturing sites not assessed by RR
First-in-class active substances
Real-world data in pivotal studies
Advanced therapy medicinal products (ATMPs) 14
The procedure includes a mandatory clock stop at Day 70, allowing applicants up to 60 days to address issues. Unresolved major objections at Day 110 trigger conversion to the national 210-day procedure 15.
Table: Comparison of IRP Recognition Routes
| Feature | Recognition A | Recognition B |
|---|---|---|
| Timeline | 60 calendar days | 110 calendar days |
| Clock Stop | Not permitted | At Day 70 (60-day response window) |
| RR Approval Age | ≤2 years | ≤10 years (exceptions possible) |
| Key Use Cases | Straightforward applications identical to RR-approved product | Complex cases (e.g., conditional approvals, manufacturing changes, novel therapies) |
| Failure Pathway | Convert to Recognition B | Convert to 210-day national procedure |
The IRP extends beyond initial approvals to cover post-authorization activities:
Line extensions (new indications/dosage forms)
Type IB and Type II variations
Renewals 13
Products initially approved via national or MRDCRP routes may transition to IRP for lifecycle management, demonstrating the procedure's operational flexibility 5.
Applicants must navigate critical preparatory steps:
Eligibility Determination: Submit an online eligibility form six weeks pre-submission to confirm suitability for Route A or B 14.
Documentation Alignment: Compile RR assessment reports and ensure Module 1 meets UK-specific requirements (other modules may follow EU eCTD format) 4.
GMP Compliance: Provide evidence of GMP certification for all manufacturing sites 1.
Portal: Applications via MHRA's Human Medicines Portal
Fees: £10,368–£96,552 depending on application type (vs. £102,300–£139,296 for national NAS applications) 4
Timeline Alignment: Recognition B submissions must align with Commission on Human Medicines (CHM) meeting dates for new active substances 1
Third-Party Applications: Possible if applicants demonstrate capability to meet UK legal obligations (e.g., pharmacovigilance) 5.
Withdrawn RR Products: Withdrawal from an RR market doesn't automatically impact UK approval but requires MHRA notification 4.
Nitrosamine Assessment: Must be completed pre-approval 4.
The IRP’s most transformative outcome is dramatically compressed approval timelines:
Route A: Average 57 days for established medicines vs. 558 days via national procedures
Route B: Average 90–110 days for NAS vs. 252+ days nationally 5.
Real-world examples like Amgen’s denosumab (Xgeva®) pre-filled syringe demonstrate this efficiency—approved via IRP just 30 days after EMA submission 4.
MHRA's operational data reveals exceptional IRP efficiency:
Type IB Variations: 97% approved within statutory time (avg. 5–8 days)
Type II Variations: 95% approved on time (avg. 21–37 days)
Initial MAAs: 100% of IRP routes met statutory timelines 35.
Cost Reduction: Saves £1–2 million per drug by avoiding redundant trials/assessments 9.
Resource Optimization: Frees MHRA capacity for innovative products without international approvals.
Investor Appeal: Positions UK as a priority launch market post-Brexit 3.
The IRP excludes:
Bibliographic applications (Article 54)
Herbal/homeopathic products
Emergency approvals 14
Products with non-identical formulations or divergent manufacturing processes versus the RR-approved product typically require national procedures 9.
Until the Windsor Framework implementation (January 1, 2025), EU Centralized Procedure products can only be authorized in Great Britain (England, Scotland, Wales), creating temporary market fragmentation 14.
Guideline Misalignment: Applications citing non-MHRA-adopted guidelines risk rejection 1.
Complex Products: ATMPs, plasma derivatives, and devices without CE/UKCA marks often trigger Recognition B or national assessments 1.
In August 2025, WHO designated MHRA a WHO-Listed Authority (WLA), affirming its alignment with global regulatory benchmarks 7. This status enables low/middle-income countries to rely on MHRA approvals—accelerating global medicine access while cementing the UK’s leadership in regulatory science 7.
AI-Enhanced Assessments: MHRA is piloting AI tools to expedite data review in IRP applications.
Procedure Expansion: Potential inclusion of medical devices and novel diagnostics under reliance pathways.
International Harmonization: Collaboration with WLAs to develop common submission standards 79.
Early Engagement: Use MHRA’s pre-submission advice service (presubmission@mhra.gov.uk) 5.
RR Selection: Prioritize regulators with identical product formulations and recent approvals.
Contingency Planning: Prepare for Route B conversion by preemptively addressing complex criteria (e.g., RMP, GMP) 45.
In a pivotal move on 7th March 2023, MHRA's advisory group unveiled plans to revolutionize medical device regulation, proposing to "build on current product recognition routes from the EU and rapidly explore building a UK product regulation equivalence route for approvals to include other trusted jurisdictions such as the US" [1]. This initiative directly parallels the medicines-focused IRP, extending the recognition philosophy to the £24bn UK medical technology sector.
As articulated by WHO [3], regulatory recognition constitutes:
"the routine acceptance by the National Regulatory Authority (NRA) in one jurisdiction of the regulatory decision of another NRA... Recognition indicates that evidence of conformity with regulatory requirements of country A is sufficient to meet requirements of country B."
This mirrors IRP's core principle but introduces unique complexities for devices due to divergent global classification systems and approval pathways.
May 2023: Chancellor's announcement confirming consultation on international device recognition by October 2023 [2]
Current (2025): EU CE mark acceptance continues until 2030 [4,5]
Post-2030: Potential indefinite CE mark recognition to ensure supply chain stability for 500,000+ devices
Table: Medical Device Recognition Framework Evolution
| Timeline | EU Recognition | Expansion Plans |
|---|---|---|
| 2021-2030 | Full CE mark acceptance | Transition period |
| Post-2025 | Conditional continuation | Consultation outcome dependent |
| Future State | Possible indefinite recognition | Multi-jurisdictional equivalence (US, Canada, etc.) |
Australia's TGA: Accepts devices approved in EU, US (non-510k exempt), Canada, Japan [6]
Singapore's HSA: Recognizes EU, US, Australian, Canadian, Japanese approvals [7]
Common Gap: Both exclude 510(k)-exempt devices - a critical consideration for MHRA
Key challenges emerge regarding US authorizations:
510(k)-Exempt Devices: Potential misalignment with UK classification (e.g., Class I non-sterile devices)
Predicate Device Reliance: MHRA's proposed "beyond EU" approach [8] may conflict with FDA's historical comparison model
Mitigation Strategy: Enhanced post-market surveillance and real-world evidence requirements could bridge regulatory differences
Patient Access: Accelerated availability of 15,000+ US-approved devices
Industry Advantages:
30% reduction in time-to-market for innovative HealthTech
Single regulatory submission for UK/US/EU markets
£150m+ annual industry savings in duplication costs
UK Sovereignty: Parallel development of UKCA route for domestically developed devices
October 2023 Consultation: Framework design for multi-jurisdictional recognition
2024-2026: Phased implementation beginning with highest-risk devices
2027 Onward: Full operationalization with AI-powered assessment of overseas data
The International Recognition Procedure for medicines and its emerging counterpart for medical devices represent complementary pillars of the UK's post-Brexit regulatory vision. By extending recognition to trusted jurisdictions like the US while maintaining EU alignment until at least 2030, MHRA creates a hybrid model that balances:
Patient safety through scientifically rigorous assessments
Market stability via extended CE mark acceptance
Innovation acceleration via US/global pathway integration
Sovereign capability through parallel UKCA development
For medical devices specifically, the October 2023 consultation will determine whether Britain becomes the world's first jurisdiction to successfully integrate EU, US and Commonwealth approval pathways into a single coherent framework. This positions the UK not merely as a regulatory follower, but as a global orchestrator of 21st century medical technology regulation.
