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   43881   clinical trials with a EudraCT protocol, of which   7295   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.

    General information about the trial
    Main objective of the trial
    The main objective of this study was to determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D), define and describe toxicities, and characterized the pharmacokinetics of orally (PO) administered ixazomib in conjunction with block 1 re-induction chemotherapy in children with relapsed/refractory acute lymphoblastic leukaemia (ALL) or lymphoblastic lymphoma (LLy).

Participants from evaluable response set who were evaluable for safety. Evaluable response set: all participants enrolled and received all or part of protocol therapy, are under follow-up for a sufficient period to evaluate disease at end of one treatment cycle or meet definition of progressive disease.

    TEAEs are defined as any AEs that occurred or worsened during the on-treatment period. TEAEs were graded using National Cancer Institute (NCI) CTCAE Version 5.0. SAEs are generally defined in this Phase 1 study as all Grade 3 and 4 events both unexpected and expected that are possibly, probably, or definitely related to Ixazomib or the chemotherapy backbone, excluding hematologic toxicities unless the event meets the criteria for a DLT.

    End point description
    Adjusted Rsq describes the goodness of fit for the terminal phase slope (log concentration vs time, used to then calculate the half-life). Evaluable response set included all participants enrolled and who received all or part of protocol therapy and are under follow-up for a sufficient period to evaluate the disease at the end of the one treatment cycle or meet the definition of progressive disease. 99999 indicates geometric coefficient of variation was not estimable for one participant.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    19 Dec 2019
    The primary purpose of the amendment 1 was to make following changes: • Dose Modification for Intrathecal Methotrexate/Triple Intrathecal Therapy toxicities: Mercaptopurine dose adjustments made to allow for genotype variations in either TPMT or NUDT15 • Dose Modification for Intermediate-Dose Methotrexate toxicities: Added subsection 4.7.7.5 to provide guidance in the event of excess extravasation of fluids into tissues (third spacing) • Clinical and Laboratory Studies: Added neurological exam to be performed prior to each Ixazomib dosing • Bone Marrow Response Criteria for participants with leukemia: amended response definitions to replace CRp category with CRi and divide the CR category to include CR MRD-.
    16 Sep 2020
    The primary purpose of the amendment 2 was to make following changes: • Exclusion criteria: updated the list of excluded CYP3A4 agents • Treatment program: under Block 1, 2, and Maintenance Block, revised timing of Leucovorin for Down syndrome Participants to be received at hours 24 and 30 after intrathecal methotrexate (IT MTX) or intrathecal triple therapy (ITT) • Dose Limiting Toxicity: changed platelet criteria for hematological toxicity definition to platelet ≥ 20,000/μL, platelet infusion independent and length of evaluation time to 49 days.
    11 May 2021
    The primary purpose of the amendment 3 was to make following changes: • Inclusion criteria: clarify the definition of what chemotherapy regimens and drugs and dosages (i.e. maintenance therapy drugs) are allowed prior to enrollment and what length of washout is required for the drugs and biologics • Treatment program: added clarification to allow for flexibility in the timing of chemotherapy administration, including the timing of Day 29 IT therapy, allowing for up to 72 hours flexibility for scheduling or other issues.
