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   44313   clinical trials with a EudraCT protocol, of which   7357   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 ).

    General information about the trial
    Main objective of the trial
    The principal question is to establish whether a single 500mg dose of RTX, when administered together with a short 12 month course of 'conventional' anti-thyroid drug (ATD), is likely to result in a meaningful improvement in the proportion of young people with Graves' hyperthyroidism entering disease remission.
    Protection of trial subjects
    None
    Background therapy
    None
    Evidence for comparator
    Young people with Graves' hyperthyroidism are managed with anti-thyroid drugs (ATD) initially but only 25% of young patients remit after a two-year course. Novel approaches to management are needed and B lymphocyte depletion with Rituximab (RTX) has shown promise in adults with Graves' hyperthyroidism. The aim of this trial is to establish whether a single dose of RTX, administered with a short course of ATD therapy, is likely to improve remission rates in young people with Graves' hyperthyroidism. 27 subjects with newly-diagnosed Graves' hyperthyroidism aged 12 to 20 years will receive a single dose of 500mg RTX within 6 weeks of commencing ATD. ATD will be stopped 12 months post RTX. Thyroid function tests, immunological markers including thyroid stimulating hormone receptor (TSHR) and peroxidase antibodies, serum immunoglobulin levels and peripheral blood lymphocyte subset analysis (including B cells [CD19]+ and class Switch memory B cells [CD27+ IgD-]) will be measured throughout the trial. The primary end-point will be the proportion of patients who are in remission off ATD 2 years post RTX. 40% or more patients in remission at 2 years following a single dose of RTX and a 12 month course of ATD would constitute a clinically meaningful improvement in outcome, above that normally observed, that would provide the foundation for a definitive trial.

    Recruitment
    Recruitment details
    The recruitment period ran from 4 November 2016 and 8 August 2018, at nine NHS hospital sites in the United Kingdom. Sites were in Birmingham (Paediatric), Leeds (Paediatric and Adult), Newcastle upon Tyne (Paediatric and Adult), Sheffield (Paediatric and Adult) and Southampton (Paediatric) in England, and Edinburgh (Adult) in Scotland.

    Pre-assignment
    Screening details
    The pre-screening assessment comprises: • Patient has excess TH concentration: elevated FT3 and/or free thyroxine • Suppressed TSH level • Elevated TRAb, including TBII ± raised TPO antibody titre • Patient (12-20 years, inclusive) has not received ATD for longer than 6 weeks at time of RTX treatment

    The Rituximab infusion will be prepared by the respective pharmacy department or according to local trust policy as per section 6.6 of the SmPC for “MabThera 500mg Concentrate for Solution for Infusion”. Each participant will receive a single dose of 500mg of Rituximab administered as an intravenous infusion at visit 1.

    CBZ is the first choice ATD in this trial but in the event of significant side-effects with CBZ (other than liver dysfunction) then participants can be switched to PTU. The increased risk of liver dysfunction with PTU will be discussed with participants and their families prior to commencing this treatment. Whilst on PTU, liver function tests should be checked at each clinic visit and PTU stopped immediately if the ALT or bilirubin are 2X outside the upper limit of the local reference range. If participants cannot tolerate or be treated with either CBZ or PTU during the first 12 months post-RTX, other potential means of maintaining a euthyroid state can be discussed with the trial management team.

    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: Statistical analysis cannot be entered, as the EudraCT report does not allow data entry for single-arm trials. The number of subjects in remission 2 years after a single dose of Rituximab and a 12-month course of ATD is 13. The proportion of subjects in remission is 0.481 (13/27); 90% lower one-sided confidence interval (0.345, 1.00). As the number of patients in remission, 13, exceeds the critical number, 9 (A'Hern design), the null hypothesis that the remission rate is ≤ 20% is rejected.
