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   43874   clinical trials with a EudraCT protocol, of which   7293   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.

    Number of Participants With Complete Thrombotic Microangiopathy (TMA) Response at Week 26 [1]
    End point description
    TMA response required the following: 1) Normalization of platelet count without transfusion support during the prior 7 days. 2) Normalization of LDH. 3) Improvement in glomerular filtration rate (eGFR) of >= 30% compared to baseline. Participants must meet each TMA criterion at 2 separate assessments obtained at least 24 hours apart, and any measurement in between. The Modified Intent-to-Treat Analysis Set included all randomized participants, excluding participants who enrolled prior to availability of ST-HUS and ADAMTS13 central laboratory results and were subsequently found to be ineligible after randomization.

    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: Due to early termination of study, no hypothesis testing for purpose of treatment comparisons was performed due to small sample size.

    Time to Complete TMA Response
    End point description
    The Kaplan-Meier estimate of time to event of complete TMA response is reported. TMA response required the following: 1) Normalization of platelet count without transfusion support during the prior 7 days. 2) Normalization of LDH. 3) Improvement in eGFR of >= 30% compared to baseline. Participants must meet each TMA criterion at 2 separate assessments obtained at least 24 hours apart, and any measurement in between. Participants who did not have a response were censored at the date of last visit or study discontinuation at the time when the analysis was performed. The Modified Intent-to-Treat Analysis Set included all randomized participants, excluding participants who enrolled prior to availability of ST-HUS and ADAMTS13 central laboratory results and were subsequently found to be ineligible after randomization. 99999 signifies too few participants experienced the event to estimate the time to event median and upper limit of 95% CI.

    Number of Participants With Renal Response at Week 26
    End point description
    Renal response is improvement in eGFR of >= 30% compared to baseline. If a participant is on dialysis ≤5 days prior to the date of eGFR assessment, the eGFR will be set to 10 milliliter/minute/1.73 meter square (mL/min/1.73 m^2) for that assessment. If a participant is on dialysis during the entire 26 week randomized Treatment Period, or through early discontinuation of study drug, then the change in eGFR was not calculated. The Modified Intent-to-Treat Analysis Set included all randomized participants, excluding participants who enrolled prior to availability of ST-HUS and ADAMTS13 central laboratory results and were subsequently found to be ineligible after randomization.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    10 Nov 2021
    The primary driver for this amendment was to allow for participants to be randomized based on local laboratory assessments (with the exception of the ST HUS screen and ADAMTS13 activity tests, which had to have been performed at the central laboratory) and allow for participants to be randomized prior to the availability of the ST-HUS screen and ADAMTS13 activity tests to align with current practice patterns for management of TMA participants. Additional changes were to update and clarify the TMA eligibility criteria, expand the window to assess eligibility for laboratory assessments to include ≤ 14 days prior to the Screening Period, define the estimands corresponding to the primary and key secondary endpoints according to ICH E9 (R1) addendum on estimands and sensitivity analysis in clinical trials, add additional endpoints to assess loss of TMA response, changes in hematological and renal response parameters, and survival, elevate changes in patient-reported outcomes as measured by FACIT-Fatigue to a secondary endpoint, update the efficacy analyses to be based on the modified Intent-to-Treat analysis set, and add COVID-19 risk assessment language.

    Interruptions (globally)

    Were there any global interruptions to the trial? No

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Planned interim analysis for sample size re-estimation and primary analysis as specified in PA2 were not conducted due to early termination of study. No hypothesis testing for purpose of treatment comparisons was performed due to small sample size.
