Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   44334   clinical trials with a EudraCT protocol, of which   7366   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    Clinical Trial Results:
    A single-arm, open-label, Phase II study of sabatolimab in combination with azacitidine and venetoclax in adult participants with high or very high-risk myelodysplastic syndrome (MDS) as per IPSS-R criteria. Due to EudraCT system limitations, which EMA is aware of, data using 999 as data points in this record are not an accurate representation of the clinical trial results.

    General information about the trial
    Main objective of the trial
    Safety run-in (Cohort 1 and Cohort 2 of Part 1): To determine whether sabatolimab is safe when added to azacitidine + venetoclax in participants with high or very high risk MDS per IPSS-R criteria. Cohort 2 of Safety run-in (Part 1) and Expansion (Part 2): To determine the complete remission (CR) rate of sabatolimab in combination with azacitidine and venetoclax in participants with high or very high risk MDS as per IPSS-R criteria treated with sabatolimab at 800 mg Q4W.
    Protection of trial subjects
    The study was in compliance with the ethical principles derived from the Declaration of Helsinki and the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines. All the local regulatory requirements pertinent to safety of trial subjects were also followed during the conduct of the trial.

    Date
    Amendment
    17 May 2021
    The purpose of this amendment was to address Health Authorities’ requests (from Belgium and France) to specify that women of childbearing potential using a hormonal contraception should add a barrier method, as stated in the venetoclax SmPC, and to add a cross-reference to venetoclax local label in the prohibited medication section. Additionally, preliminary results of the first cohort of the safety run-in of CMBG453C12201 study were included. The pharmaceutical dose form and route of administration terms for azacitidine were updated to be in alignment with other sabatolimab protocols.
    06 Oct 2021
    The purpose of this amendment was to clarify DLT criteria to specify that prolonged cytopenias beyond Day 42 from the start of a study treatment cycle should be considered DLTs and to clarify language around intercurrent events in the estimand section as well as analysis of duration of response. Additionally, language around COVID-19 vaccines and time frame for SAE follow-up reporting was added.

    Interruptions (globally)
    Were there any global interruptions to the trial? No
