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.

Two new advice pilots to improve clinical trials in Europe 

The Accelerating Clinical Trials in the EU (ACT EU) initiative is today launching two advice pilots aimed at improving the quality of applications for clinical trials, the foundation for the development of safe and effective medicines in Europe.

ACT EU is a collaboration between the European Medicines Agency (EMA), the Heads of Medicines Agencies (HMA) in the Member States and the European Commission (EC), which seeks to transform how clinical trials are initiated, designed, and run.

The first pilot offers developers of medicinal products scientific advice on clinical trials and on requirements for marketing authorisation applications (MAA). Assessors of clinical trials are not consistently involved in scientific advice procedures for MAAs, and vice versa. In this pilot programme, the Scientific Advice Working Party (SAWP), coordinated by EMA, and the Clinical Trials Coordination Group (CTCG), managed by HMA, will be the bodies assessing incoming requests of a scientific nature. The SAWP is responsible for advice on marketing authorisation applications and the Member States represented at CTCG oversee clinical trial applications (CTA). This pilot consolidates the views of these two groups to minimise avoidable divergences. It is the first time that both entities are providing joint scientific advice on clinical trials.

The second pilot is coordinated by the CTCG and provides technical and regulatory support on the dossier of a CTA prior to its submission through the Clinical Trials Information System. Before this pilot, applicants could only receive technical and regulatory support at national level from the Member State evaluating the application. The pre-CTA pilot will provide consolidated views of the Member States concerned on pre-submission topics. The scope of this pilot covers a number of areas such as advice on regulatory aspects of low interventional clinical trial status and submission of trials with decentralised elements or complex designs, to name a few.

Starting today, developers of medicinal products who wish to receive advice on the requirements for a MAA or a CTA may apply to these pilots. The duration of both pilots will be evaluated over time based on data and feedback collected from applicants. All this information will inform a possible change of scope and a final decision from the ACT EU steering group on how to optimise clinical trial support in the future.

By strengthening the coordination of the European medicines regulatory network, these advice pilots offer applicants additional support to enhance the quality of their applications for marketing and/or clinical trial authorisation.

Guidance for applicants: pre-CTA advice pilot

Guidance for applicants: SAWP CTCG pilot on scientific advice

Simultaneous National Scientific Advice (SNSA)

SNSA is intended to be used in situations where an applicant wishes to obtain national scientific advice from more than one NCA at the same time. The format is intended to enhance the quality and consistency of such advice. Following endorsement by the Heads of Medicine Agencies (HMA), phase 2 of the SNSA pilot will run for a two-year period until the end of 2024.

In conjunction with the ACT-EU initiative, this phase of the SNSA pilot will have a specific focus on scientific advice to facilitate clinical trials (CT) within Europe. It will facilitate sponsors / developers to obtain clinical trial-related national scientific advice from National Competent Authorities (NCA) in Member States (MS) where they intend to perform clinical trials. The experience gained during the SNSA pilot will be used to further develop the process and the provision of clinical trial-related advice as part of ACT EU Priority Action 7 (ACT EU PA7).

The following are examples of scenarios where developers may choose to seek SNSA:

• In preparation for clinical trials (CT) applications to be performed in more than one MS. Where during the SNSA the involved NCAs agree that the questions raised would benefit from discussions at the Clinical Trial Coordination Group (CTCG) level, it is also possible to obtain CTCG-coordinated clinical trial expert feedback as part of the SNSA procedure.
• Prior to applying for funding grants to support non-commercial clinical trials (academic researchers).
• To inform the early-stage development of innovative products for which clinical trials are planned, e.g. phase I/II clinical trials, especially where there is limited existing regulatory guidance. EMA scientific advice should continue to be used for scientific advice related to the suitability of the proposed clinical development to support a centralized marketing authorisation application.
• Prior to clinical trials intended to facilitate repurposing of authorised medicinal products e.g. to support new innovative therapeutic indications.

More detailed information on how to apply for SNSA and additional documents and information can be found at Heads of Medicines Agencies: EU-Innovation Network (EU-IN) (hma.eu) (search for SNSA).

In order to clarify the scope of scientific advice activities, ACT EU mapped information on voluntary procedures available within the European medicines regulatory network: Accelerating Clinical Trials in the EU (ACT EU) | European Medicines Agency (europa.eu) (look at PA 7).

Decentralised Clinical Trials (EU DCT)

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.

CTCG Best practice Seasonal Vaccines for sponsor

CTCG has set up a new best practice on submission and handling of clinical trial applications concerning seasonal vaccines clinical trials. This guide considers special conditions relevant for clinical trials on seasonal vaccines due to the dependence of trial start in relation to expected infection waves or seasonality, as sponsors have only very limited timeframes available to manufacture and fully characterize clinical trial batches after the relevant strains have been communicated. The document provides instructions for sponsors on modified timelines for submission and procedural steps concerning such trials.

CTIS Guidance

• Best practice guide naming of documents in CTIS | pdf
  CTCG has set up a best practice for the naming of documents in CTIS. The purpose of this naming convention is to provide a harmonised structured overview of the documents in the clinical trial application dossier, in alignment with the document types referred to in the sections of CTR annex I and II. This guide provides instructions on how to use the naming of documents in CTIS and on the use of the EU trial number within documents. CTCG accepts that the CT numbers within the documents uploaded into the system do not include the last 2 digits, so that they do not need to be changed for re-submission. Any feedback on this best practice guide for naming of documents can be sent here.

Complex Clinical Trials

• 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.

Clinical Trial Safety

• QnA on Safety Addendum V2 clarifies topics in addition to section 7 of QnA in EudraLex Vol10, regarding Annual safety report, safety relevant notifications, reference safety information and request for information send within the ‘adhoc’ workflow which is used for supervison of CTs.
• CTCG’s developed a Simplified template of Annual Safety Report, March 2025.
  Non-commercial sponsors conducting a single clinical trial on IMPs with a MAH in any of the EU/EEA member states and where the SmPC is used as RSI submitting this simplified ASR based on the ICH-E2F may be appropriate. This template gives detailed instructions on what information is expected and what may be omitted in this setting. The simplified ASR should always be written in English.

Other Guidance and Q&A Documents

• CTCG jointly issues a new recommendation paper on principles of Good Laboratory Practices (GLP) for clinical trial applications under the EU Clinical Trials Regulation (Regulation (EU) No 536/2014), together with relevant EMA and EC working groups and parties. The aim is to provide transparency on the requirements and to clarify the expected level of information on the GLP status to include in the Clinical Trial Application in support of this.
