Examples
Worked examples
- Is an instance
A Phase III trial of an investigational medicinal product across multiple Irish hospital sites is reviewed by NREC-CT, in a coordinated procedure with the HPRA, rather than by each hospital's local ethics committee.
- Is an instance
A clinical investigation of an implantable medical device, run to generate data for a future regulatory submission, is reviewed by NREC-MD as a regulated device study.
Counter-examples
Looks similar, but isn't
- Not an instance
A retrospective observational chart review at an HSE-funded hospital, involving no investigational medicinal product or device, is not a Regulated Clinical Trial and is instead reviewed by the local HSE Research Ethics Committee, not the NREC.
Editorial commentary
The National Office for Research Ethics Committees (NREC) is the statutory body in Ireland responsible for establishing, resourcing, and administering the National Research Ethics Committees that provide ethical review for legally regulated categories of health research. It was established in 2020 as a business unit of the Health Research Board (HRB), which supports its operational and strategic work, and its statutory function derives from the European Union (Clinical Trials on Medicinal Products for Human Use) (National Research Ethics Committees) Regulations 2022, implementing Ireland’s obligations under the EU Clinical Trials Regulation (Regulation (EU) No 536/2014) and parallel medical-device legislation.
What the National Office actually does
The National Office does not itself review protocols. Its role is to constitute, staff, and support a small number of National Research Ethics Committees (NRECs), each with a defined regulated scope:
- NREC-CT — clinical trials of investigational medicinal products for human use, regulated under the EU Clinical Trials Regulation.
- NREC-MD — clinical investigations of medical devices.
- NICB-REC — the National Irish COVID-19 Biobank.
- NREC COVID-19 — a committee stood up specifically for COVID-19-related research.
For studies within their regulated scope, these committees issue a single national ethics opinion for the whole of Ireland, replacing what would otherwise be separate reviews by multiple local committees. The National Office works closely with the Health Products Regulatory Authority (HPRA), Ireland’s competent authority for medicines and devices, so that the scientific/regulatory assessment (HPRA) and the ethics opinion (NREC) proceed on a coordinated, parallel timeline rather than as two disconnected approval tracks.
Operational definition: when a study needs NREC review
A study is in NREC scope, rather than local Research Ethics Committee scope, when it meets both of the following:
- It is legally a Regulated Clinical Trial of a medicinal product under the EU Clinical Trials Regulation, or a regulated clinical investigation of a medical device under the applicable EU medical-devices framework (or falls within one of the other committees’ defined remits, such as the national COVID-19 biobank).
- Ethical approval for that specific regulated activity in Ireland is being sought as a single national opinion, not a per-site or per-institution one.
Everything outside that narrow, legally defined scope, most observational research, most social-science and public-health research, and research conducted within Ireland’s public health system that isn’t a regulated trial or device investigation, is reviewed by local ethics committees, most commonly a HSE or Hospital Research Ethics Committee, or a university/institutional Research Ethics Committee (REC).
Worked examples
Example 1 — NREC-CT applies. A pharmaceutical sponsor plans a Phase III randomised controlled trial of an investigational drug across several Irish hospital sites. Because this is a Regulated Clinical Trial under EU Regulation 536/2014, the sponsor submits in parallel to the HPRA (scientific/regulatory assessment) and to NREC-CT (single national ethics opinion), rather than seeking separate ethical approval from each participating hospital’s local REC.
Example 2 — NREC-MD applies. A medical-device manufacturer needs to run a clinical investigation of an implantable device to generate performance data ahead of a regulatory submission. Because this is a regulated device clinical investigation, ethical review sits with NREC-MD, again coordinated with HPRA rather than with a local hospital committee.
Counter-example
An academic research team at an Irish HSE-funded hospital wants to run a retrospective observational chart review of patient outcomes, with no investigational medicinal product or device involved. This is not a Regulated Clinical Trial or regulated device investigation, so it does not fall to the NREC — it is reviewed by the relevant HSE Research Ethics Committee (or an equivalent local/institutional REC), which is a separate, broader-remit body from the National Office and its NRECs.
NREC vs. HSE Research Ethics Committees
These two are easy to conflate because both operate within the Irish public research-governance landscape, but their scope, legal basis, and institutional home are distinct:
- Legal basis: NREC’s committees exist under the EU Clinical Trials Regulation and the 2022 National Research Ethics Committees Regulations, giving them a narrow, statutorily defined remit. HSE Research Ethics Committees operate under the HSE’s own research-governance framework and cover the much broader run of health research conducted in or through the public health system.
- Host organisation: the National Office is hosted by the Health Research Board (HRB), a state agency independent of the HSE; HSE RECs are constituted by the Health Service Executive and individual HSE-funded hospitals.
- What they review: NREC committees review only regulated clinical trials of medicinal products, regulated device clinical investigations, and the specific COVID-19-related remits above. HSE RECs review the far larger volume of non-regulated health research, observational studies, audits, most academic clinical research, taking place within the HSE system.
- Number of opinions: a study in NREC scope gets one national ethics opinion covering all Irish sites; a study reviewed by an HSE REC is approved through the relevant local or hospital-group committee.
In short: NREC is Ireland’s single, statutory, EU-regulation-driven ethics review pathway for regulated clinical trials and device studies; HSE RECs are the broader, locally constituted review bodies for the rest of Ireland’s public-system health research. A researcher unsure which applies should check whether their study is legally a Regulated Clinical Trial or regulated device clinical investigation — if so, NREC applies; if not, a local HSE/Hospital REC is the relevant body.

"description": "The NREC (National Office for Research Ethics Committees) is the statutory Irish body, hosted by the Health Research Board (HRB) since 2020, that establishes and administers Ireland's National Research Ethics Committees for legally regulated research: clinical trials of investigational medicinal products (NREC-CT) and clinical investigations of medical devices (NREC-MD), plus committees stood up for specific national needs such as the National Irish COVID-19 Biobank (NICB-REC) and COVID-19 research (NREC COVID-19). A study falls under NREC review, rather than a local HSE, hospital, or university Research Ethics Committee, when it is a Regulated Clinical Trial under the EU Clinical Trials Regulation (536/2014) or a regulated medical-device clinical investigation, in which case a single national ethics opinion from the relevant NREC is required, issued in a coordinated procedure alongside the scientific/regulatory assessment carried out by the Health Products Regulatory Authority (HPRA). Outside that regulated scope, most observational studies, most academic health and social-care research, and research within the HSE and HSE-funded hospitals, ethical review remains the responsibility of local HSE and Hospital Research Ethics Committees, not the NREC.",
