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 ).

    Clinical Trial Results:
    Phase II, single arm, multicenter trial to determine the efficacy and safety of CTL019 in pediatric patients with relapsed and refractory B-cell acute lymphoblastic leukemia. 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
    To evaluate the efficacy of tisagenlecleucel therapy from all manufacturing facilities as measured by overall remission rate (ORR) during the 3 months after tisagenlecleucel administration, which includes complete remission (CR) and CR with incomplete blood count recovery (CRi) as determined by Independent Review Committee (IRC) assessment.
    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.

    Recruitment
    Recruitment details
    98 patients were enrolled & 80 patients were infused in this study: 79 in the Main Cohort and 1 in Cohort 1. No patients were infused in Cohort 2. "Enrolled" means all eligibility criteria were met & apheresis was accepted by the manufacturing facility. Patients could discontinue the trial after enrollment and prior to tisagenlecleucel infusion.

    Pre-assignment
    Screening details
    This study was conducted in 11 countries with 23 sites.

    Notes
    [1] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.
    Justification: This number is explaining the participants who entered the study but were not infused - a requirement to be considered as truly participating in the study.

    [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: There is a statistical analysis done comparing the one group to fixed values of threshold, but the EudraCT system gave an error message when this was presented, stating that there has to be at least 2 comparison groups for a statistical analysis to be provided. So, the statistical analysis was removed.

    End point description
    The PedsQL questionnaire was for patients ≥ 8-years-old who achieved BOR as CR or CRi within 3 months and the questionnaire was on emotional, social, school, physical, and psychosocial health. Scores are transformed on a scale from 0 to 100, with the sum of all the items over the number of items answered on all the scales. Higher scores on the PedsQL questionnaire for these subscales indicate consistent improvement of health-related quality of life (HRQol).

    Effects of CTL019 therapy on Patient Reported Outcomes as measured by EQ-5D questionnaire
    End point description
    Results from the EQ-5D questionnaire is for number of participants who achieved CR or CRi at month 60. The EQ-5D descriptive system comprises 5 dimensions: mobility, self-care, usual activities, pain & discomfort, anxiety & depression. Respondents are asked to choose the statement in each dimension that best describes their health status on the day surveyed. Their responses are coded as a number (1, 2, or 3) that corresponds to the respective level of severity: 1 indicates no problems, 2 some problems, and 3 severe problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the 5 dimensions. This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the 5 dimensions can be combined into a 5-digit number that describes the patient’s health state. The scores are then normalized to a value from 0-100 where higher scores = better HRQOL & fewer problems or symptoms.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    04 Feb 2015
    The window between informed consent and tisagenlecleucel infusion was widened from 8 weeks to 16 weeks. - Included additional safety information to address FDA requirements for CRS, deaths, follow-up after live birth. - Updated secondary endpoints to include expression of tisagenlecleucel in blood and bone marrow by flow cytometry and some exploratory endpoints - Updated study design diagram with extended windows from ICF to infusion. - Updated vital signs follow-up post tisagenlecleucel infusion. - Changed age at Screening from 2 years at initial diagnosis to 3 years at Screening. - Added an additional inclusion criteria to confirm patient met local institutional criteria for leukapheresis. - Added resource utilization to capture hospitalizations. Added PROs.
    22 May 2015
    - Modified to include that the FAS should contain at least 50 patients < 18 years (of which 10 patients should be < 10-years-old). The total number of planned patient enrolment was increased accordingly to approximately 78. - Upgraded MRD by PCR from secondary to key secondary endpoint, based on its relevance as a surrogate marker correlated with clinical benefit in p-ALL. - Upgraded CRS, safety monitoring, and PROs endpoints from exploratory to secondary endpoints. - Added derivation of a score to predict CRS as a secondary objective. - Changed Day 28 tumor assessment window from ±7 days to ±4 days. - Additional analyses had been included to assess the response at Day 28±4 days, impact of Baseline tumor burden on response, etc. - Extended healthcare resource utilization collection visits. - Removed PedsQL questionnaire collection in children ages 5 to 7 years.
    13 Apr 2016
    - Expanded target tisagenlecleucel dose range for patients > 50 kg and defined allowable dose ranges. - Extended the allowance of more than 10 patients ≥ 18 years old. - Updated the CRS algorithm and management guidelines (including the use of siltuximab). - Updated pediatric ALL efficacy guidelines. - Updated the AESI list to include: febrile neutropenia, infections, transient neuropsychiatric events, and hematopoietic cytopenias lasting ≥ 28 days.
    14 Jun 2016
    - Updated the definition of the primary efficacy endpoint. Based on published data with tisagenlecleucel, clinical trial experience thus far, and based upon discussions with FDA, the post infusion follow-up duration for assessing the primary objective of ORR for each patient was changed from 6 months to 3 months. - Added the EU manufacturing facility as an additional manufacturing facility and increase the enrolment target to allow up to 14 patients treated with tisagenlecleucel from this facility. - Defined two new key efficacy endpoints to allow evaluation of ORR and MRD-negative ORR only for tisagenlecleucel manufactured at the US facility.
    04 Apr 2017
    - Enrolled 5 additional Japanese patients in the study to include at least 3 additional patients infused with tisagenlecleucel manufactured from the US facility. - Provided a modified CRS management algorithm for Japanese patients as anti-IL6 drugs other than tocilizumab are not available in Japan.
    21 Mar 2019
    - Additional 20 patients to be screened in the two cohorts and at least 15 of them to be treated with tisagenlecleucel - (1) pediatric ALL patients who are very high risk at the time of first relapse; (2) relapse within 6 months of an allogeneic HSCT. This recruitment was limited to the US sites. - Changed CRS grading scale to Lee et al 2014 and updated the CRS management algorithm.
    26 Oct 2020
    - Terminate the enrollment into Cohorts 1 and 2 as patient enrollment was low subsequently, due to availability of alternative treatment options. One patient was treated in Cohort 1 and no patient was enrolled or treated in Cohort 2. A notification was sent to FDA on 26-Jun-2020 to communicate the decision to terminate patient enrollment to these two cohorts. - Change the follow-up requirement to determine the outcome of a pregnancy. This additional safety monitoring was not due to any new safety concern, but a precautionary measure. - Add the requirement for pregnancy testing at all study visits. - Clarify the requirements for laboratory testing (to include RCL testing) in the case of secondary malignancies and specify that blood samples for RCL testing were to be stored beyond Month 12, as long as all samples through Month 12 were negative.
