Clinical Trials Coordination Group (CTCG)


CTCG Introduction/Overview/Mandate

The CTCG is an HMA working group of experts in the classification, assessment and oversight of clinical trials from National Agencies.

The objective of CTCG is to contribute to increasing the attractiveness of the EU/EEA for clinical trials by harmonisation and optimisation of the regulatory environment while assuring the protection of rights, safety and wellbeing of the subjects and the generation of robust data.

Early clinical trials are the first contact of regulators with innovation. CTCG will monitor these trends and evolutions in clinical trials and will develop and publish guidance documents.

The EU Decentralised Clinical Trials (EU DCT) project | pdf

  • Since March 2022, the Clinical Trials Coordination Group (CTCG) is responsible for the project management of the EU Decentralised Clinical Trials (EU DCT) project.
    The EU DCT project is part of the priority actions conducted in the context of the Accelerating Clinical Trials in the EU (ACT EU), which started at the same time as the launch of the Clinical Trials Information System (CTIS) and the implementation of the Clinical Trials Regulation (EU) No 536/2014 (CTR).
    The DCT project represents a broad collaboration across the European Medicines Regulatory Network with a cross-disciplinary project group including amongst others clinical trial authorisation experts, ethical experts and Good Clinical Practice (GCP) inspectors across Member States.
    It aims to provide a harmonised and transparent approach for the use of DCT elements in clinical trials. To this end, a Recommendation paper on the use of DCT elements in clinical trials is planned to be published by the end of 2022.


  • Best Practice Guide for Sponsors of document naming in CTIS | pdf
    In order to simplify the re-submission process to CTIS CTCG accepts that the CT numbers within the documents uploaded into the system are shortened concerning the last 2 digits which only show how often the sponsor created previous submissions and re-submitted the applications.
    In case of a decision letter the full number including the last 2 digits will be reflected.
    If the full number is reflected in the documents and a re-submission takes place, there is no expectation that these numbers are immediately corrected within the documents during the ongoing procedure. This can be done at a later stage when the documentation is updated during a SM procedure.
  • Complex clinical trials (CCTs) – Questions and answers
    The European Commission, EMA and CTCG have jointly issued new "Complex Clinical Trials - Questions and Answers" document for which “Recommendation Paper on the Initiation and Conduct of Complex Clinical Trials” issued in 2019 by the former CTFG has served as a basis. This document provides clarification or additional information and lays out certain considerations regarding scientific aspects, planning and set - up, submission for obtaining CT authorization (CTA), conduct, reporting and transparency, analysis and interpretation of Complex Clinical Trials (CCTs) under the EU Clinical Trials Regulation 536/2014 (CTR) and EU In Vitro Diagnostic Medical Devices Regulation 2017/746 (IVDR), as well as their use in submissions for marketing authorization.

    The changes are as follows:
    • after the relevant systemic exposure to the medicinal product has ended for exposure to other types of genotoxicants than aneugenic compounds, the duration for applying highly effective contraception measures for women of childbearing potential, has been extended from 1 month to 6 months (one folliculogenesis cycle).
    • the need for informing participants to seek advice about donation and cryopreservation of germ cells in line with this guidance prior treatment if applicable, has been added to the section on the need for sexual counseling of study subjects, e.g. in adolescents, which should be reflected in the protocol.

    SAFE CT - Safety Assessment Cooperation and Facilitated Conduct of Clinical Trials

    Safety Assessment Cooperation and Facilitated Conduct of Clinical Trials (SAFE CT) | pdf

    The new Clinical Trial Regulation EU No. 536/2014 and Implementing regulation (IR) which came into force on 31 Jan 2022 introduced the concept of safety cooperation and work-sharing among Member States (MSs)

    Joint Action (JA) 12 of the EU4Health Safety Assessment Cooperation and Facilitated Conduct of Clinical Trials or SAFE CT supports these new concepts through provision of additional resources and expertise necessary to implement the new regulation.

    The goal of this JA is to establish and maintain cooperation in safety data assessment in clinical trials via building capacities and performing training activities in the participating MSs. The experience gained during the JA will be used to update and improve the procedures on cooperation and training in safety surveillance in clinical trials.

    The project is currently in grant management phase and will run for 36 months (with a retrospective start date from 01/05/2022 to 30/04/2025).


    First Annual SAFE CT Safety Assessor Event

    The first Annual SAFE-CT Safety Assessor Event was held in Amsterdam at the offices of the EMA on 30-31 January. The event included plenary sessions from external experts in medicines regulation and pharmacovigilance as well as in paediatric oncology and in paediatric clinical trials in addition to workshops on Annual Safety Report (ASR) and Suspected Unexpected Serious Adverse Reaction Report (SUSAR) assessment. The event was attended by 52 participants from 26 countries and it was the first of 3 such events planned for the lifecycle of the Joint Action, the focus of which is the exchange of experience and knowledge and the fostering of cooperation in safety assessment across the network. Further information on the event is highlighted in the 13th edition of the 'Clinical Trials highlights' newsletter.
