    Clinical Trial Regulation and CTIS

    ​​CTIS will be the single entry point for submitting clinical trial information in the EU and the European Economic Area (EEA). CTIS will contain a Sponsor workspace for clinical trial sponsors and the organisations that work with them, an Authority workspace for EU Member States, EEA countries and the European Commission, and a public website.

    • The Sponsor secure workspace will assist clinical trial sponsors in preparing and compiling the clinical trial application and related documents to submit for assessment.
    • The Authority secure workspace will support the activities of EU Member States, EEA countries and the European Commission in assessing and overseeing clinical trials.
    • Through the public website, members of the public can access detailed information on all clinical trials conducted in the EU and the EEA once trials start to be submitted and approved in CTIS.

    ​EU Member States and EEA countries will assess and supervise clinical trials in CTIS, while EMA maintains and develops CTIS. The European Commission ensures the correct interpretation and implementation of the Clinical Trials Regulation.

    How clinical trials will be processed in CTIS

    Clinical trial sponsors who want to gain regulatory approval for a clinical trial in one or more EU Member States and EEA countries will submit a single clinical trial application form and supporting dossier through CTIS. The submission of the single clinical trials application form and supporting dossier will also include the public registration of the clin​ical trial.

    CTIS will support the day-to-day business processes of EU Member States, EEA countries and sponsors throughout the lifecycle of a clinical trial. It will provide regulatory oversight of clinical trials and tools for supervision and monitoring.

    How to register for CTIS

    Clinical trial sponsors that want to use CTIS must ensure their users have an EMA account. Users that have already an EMA account, for example to use Eudravigilance or the substances, products, organisations and referentials database (SPOR) do not need to create a new account. Users that do not have an EMA account can register via EMA Account Management.

    Clinical trial sponsors may need to complete additional registration steps based on the user management approach they choose for CTIS. The organisation-centric approach allows for the management of users by an administrator at the organisation level rather than at the level of an individual trial. It is intended for organisations that will run several trials in CTIS. To make use of the organisation-centric approach, organisations must ensure they are registered in EMA's Organisation Management System (OMS), and they must register a CTIS High Level Administrator via EMA Account Management.

    How to prepare for CTIS

    Clinical trial sponsors can consult the CTIS Sponsor Handbook for guidance on how to prepare for CTIS.

    In addition, clinical trial sponsors can use the CTIS online training programme. The guide to the CTIS training material catalogue, which can be found on the training programme page on the EMA website, provides an overview of the training programme.​
