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   43865   clinical trials with a EudraCT protocol, of which   7286   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    Recruitment
    Recruitment details
    Participants took part in the study at 65 investigative sites in 12 countries.

    Pre-assignment
    Screening details
    The original planned enrollment was 1062 participants across 3 treatment arms. With Protocol Amendment 05 the Epacadostat + Pembrolizumab (E+P) arm was dropped, and the planned sample size was reduced to a total of 148 participants randomized into the 2 remaining arms. 233 participants were randomized and 228 participants received study treatment.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    17 Jul 2017
    Updates to SoA; Serotonin syndrome; clarity to DMC review
    17 Oct 2017
    Dose modification and toxicity management guidelines for myocarditis. Melatonin and propofol removed from exclusion criteria and from the list of prohibited medications.
    01 May 2018
    Amended from a Phase 3 to a Phase 2 design, with ORR as the primary endpoint and PFS, OS, DOR as secondary endpoints due data from the Phase 3 KEYNOTE-252/ECHO-301. Removed Pembro + Epa arm, reduced number of patients to be enrolled to 148 and removed interim analysis.
    04 Mar 2019
    Data from the final analysis of KEYNOTE-715/ECHO-306 (data cutoff: 13-DEC-2018) indicated that the study did not meet the prespecified endpoint of improvement in objective response rate (ORR) for the combination of pembrolizumab plus epacadostat plus chemotherapy compared with pembrolizumab plus chemotherapy plus placebo. Based upon these data from the final analysis, the Sponsor and MSD implemented this Amendment 06 to direct that all epacadostat and placebo administration stop and to reflect that the study is no longer blinded. The study remained open so participants still on study will have continued access to pembrolizumab.
