The Need for EU Legal Representation in Clinical Trials

Any biopharmaceutical company that plans to conduct clinical trials in the EU and doesn’t have a registered office in the European Economic Area (EEA), needs to use the services of a Legal Representative. This provision, first established in 2001, aims to ensure that the EU offers an attractive and favorable atmosphere for carrying out clinical research on a large scale, with high public transparency and safety standards for the clinical trial participants. If you are a Sponsor who is interested in conducting clinical trials in the EU then, according to the EU Clinical Trials Regulation No 536/2014 (CTR), you need to appoint a Legal Representative with an established office in the EEA.

In case trial-related legal proceedings are initiated within the EU/EEA, a Legal Representative acts as the agent of a Sponsor. It is important to note that a Legal Representative does not accept any of the legal rights and responsibilities of the Sponsor. Its role is to act as a liaison between the Sponsor and the competent EU entities and to perform the activities that are specified in the Letter of Authorization.

The Main Services Provided by the Legal Representative

  • To help the Sponsor understand the EU legal requirements.
  • To maintain direct contact with the regulatory authorities. 
  • To be accountable for patient safety, to investigate fraud, or other non-compliance matters that are under the jurisdiction of the EU courts.

The Logistics of Legal Representation

  • The Sponsor may select only one Legal Representative for a specified trial.
  • The Legal Representative can be located in any EU member state, regardless of the member state(s) in which the trial will be conducted.
  • A Letter of Authorization must be initiated on the Sponsor’s letterhead, which includes a declaration by the Legal Representative for the assumed role.
  • A Letter of Authorization must be included in the initial submission dossier to a Competent Authority or Ethics Committee.
  • The Sponsor may appoint different Legal Representatives for different trials.

Responsibilities of the Legal Representative

  • To assist the Sponsor in understanding the EU regulatory provisions.
  • To devise a tailored solution that ensures compliance with EU regulations.
  • To stay up to date on newly issued legal regulations and to communicate them to the Sponsor in a timely manner.
  • To assist in coordinating site inspections that assure compliance with the International Conference of Harmonization (ICH) and Good Clinical Practice (GCP).
