Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   42758   clinical trials with a EudraCT protocol, of which   7042   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System

    General information about the trial
    Main objective of the trial
    The primary objective is to restore adrenal function in patients with recent onset autoimmune Addison's disease. This study will answer the following questions: In people with new-onset autoimmune Addison’s disease will the therapeutic regimen of rituximab and ACTH allow improvement or recovery of adrenal function?
    Protection of trial subjects
    Rituximab infusion can be associated with transient adverse reactions in 50% of people including rash, flushing, shivers, fever, runny nose, hypotension, hypertension. Premedication with methylprednisolone, paracetamol and piriton will be given to minimise the risk of reactions. ACTH injections will be self administered subcutaneously every other day for the first 12 weeks, going to twice a week during week 12-16 and once weekly weeks 16-20. There is frequently itchiness and discomfort over the injection site that lasts for 48-72hrs. Bruising and swelling may also occur. Two education sessions about the best technique for avoiding pain and bruising at the injection sites will be given.

    Change in peripheral B lymphocyte count at 72 weeks.
    End point description
    Change in peripheral B lymphocyte count at 72 weeks. CD19+ population expressed as a percentage of parent lymphocyte population. 10,000 lymphocyte events counted twice for each measurement. Complete depletion was judged as CD19+ <0.1% of lymphocytes. 12/13 patients achieved CD19+ lymphocyte counts measured as 0.0 or 0.1% of the parent population following treatment with rituximab. These included NCL06 who achieved the highest peak cortisol post-intervention and NCL08 who achieved the secondary outcome measure of a rise in cortisol of 100nmol/L post-intervention. In most patients, counts remained low for several months (minimum 12 - maximum 48 depleted weeks), with CD19+ population counts measured as 0.0 - 0.2% of parent population across several major outcome visits. Resurgence (>0.05%) of parent population) was detectable in all patients by the end of study and occurred after a mean period of 48 week (SEM 3.84).
