Complying with the Clinical Trials Regulation: Guidance for sponsors

As part of the new Regulation, sponsors have new requirements to comply with. Sponsors should use the resources listed below to comply with the Regulation, which includes using CTIS. 

Transition period ends 31 January 2025

There has been a transition period for clinical trial sponsors to fully comply with the new regulation. This transition period ends on 31 January 2025. This means that all clinical trials approved under the previous Directive must now be recorded in CTIS. 

Support for implementing the CTR

Sponsors can consult the resources published by the HPRA, the HMA and the European Commission. For CTIS resources, see the CTIS section below.

HPRA guide to conducting clinical trials in Ireland

The HPRA has compiled regulatory requirements for sponsors into a guidance document. Sponsors should use this document to help them comply with requirements for topics including:

  • safety reporting
  • supervision
  • archiving
  • appeals
  • good clinical practice (GCP) inspections 

HMA resources

The HMA's Clinical Trials Coordination Group has published guidance documents and templates, such as cover letter templates for initial applications and substantial modifications. You can view and download these documents on the HMA CTCG resources page.

European Commission resources

Eudralex Volume 10 contains guidance documents for sponsors. A number of documents in Volume 10 were updated to bring them in line with the CTR. Additionally, new documents were published to cover new aspects introduced by the CTR. View the resources on the Eudralex Volume 10 page

Extra support for non-commercial sponsors (ACT EU)

The ACT EU initiative aims to address problems that make it challenging for non-commercial sponsors, such as academic sponsors, to run clinical trials, especially across multiple countries. ACT EU will propose practical and harmonised solutions to help these sponsors conduct trials more easily throughout the EU.
