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:
    Phase Ib/II, open label study of sabatolimab as a treatment for patients with acute myeloid leukemia and presence of measurable residual disease after allogeneic stem cell transplantation. 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
    For adults only (from the safety run-in part): To determine whether sabatolimab as monotherapy at the two tested dose levels (400 mg and 800 mg Q4W) leads to an unacceptable level of toxicity when administered to adult participants with AML who are in complete remission but are MRD+ post-aHSCT. For adults only (from both safety run-in and expansion parts): To evaluate preliminary efficacy of sabatolimab (at the recommended dose level for expansion) as monotherapy and in combination with azacitidine on prevention of hematologic relapse by assessing the proportion of adult participants with AML and MRD+ post-aHSCT,) who remain with no evidence of hematologic relapse after 6 cycles of study treatment. For adolescents only: To determine whether sabatolimab as monotherapy at the recommended dose level for adults leads to an unacceptable level of toxicity when administered to adolescent participants with AML who are in complete remission but are MRD+ post-aHSCT.
    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.

This was determined by the number of participants with at least one event - All grades.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    16 Apr 2021
    Amendment #1: - In response to a request from health authorities, the list of inclusion and exclusion criteria was revised. The modification includes the addition of required minimum hemoglobin level, as well as restrictions for prior cancer-directed treatment or investigational modalities and for patient with BCR-ABL mutations eligible for post-transplant tyrosine kinase inhibitor therapies; - Clarification was provided on the dose used in cohorts 3-5, to define DLTs and dose modifications handling for sabatolimab by the request of health authorities; - Revisions were made to the visit schedule assessments tables to add/correct the visit windows. additionally, amendment was implemented to differentiate the collection of antineoplastic therapies/medications since discontinuation which was previously included in collection concomitant medication and therapies; - Changes included removal of immunogenicity (IG) sample collection after sabatolimab post-infusion at Cycle 24, as pre-infusion collected sample at this visit was sufficient.
    24 Mar 2022
    Amendment #2: - The restrictive list of inclusion and exclusion criteria was modified per feedback provided by the Principal Investigators to increase the recruitment rate. These changes did not substantially impact the study design or the primary objectives, which included safety and preliminary efficacy assessments. An amended protocol was implemented to include the determination of eligibility for enrollment based on central MRD assay. These modifications allowed for a more comprehensive assessment of patient eligibility during the course of the study.
