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 ).

    General information about the trial
    Main objective of the trial
    The primary objective of the research project is to determine the change in the psoriasis area and severity index (ΔPASI) during 16 weeks of treatment with a dipeptidyl peptidase-4 inhibitor (Januvia®, 100mg daily) in psoriasis patients with type 2 diabetes. This will be compared to the ΔPASI in psoriasis patients with type 2 diabetes during 16 weeks of treatment with a comparator (Diamicron®, 80mg to 320mg daily).
    Protection of trial subjects
    If a participant’s plasma glycated haemoglobin level (HbA1c) was above 64mmol/mol eight weeks after commencing one of the study IMPs insulin therapy was used to improve glycaemic control. The Summary of Product Characteristics (SPC) states that the dose of Januvia® is 100mg once daily (using tablets for oral ingestion). For research participants with moderate kidney disease (CrCl < 50 ml/min or eGFR < 50 ml/min/1.73m2), the Summary of Product Characteristics (SPC) states that the dose of Januvia® is 50mg once daily (using tablets for oral ingestion). In keeping with this all participants with an eGFR < 50ml/min/1.73m2 who were due to receive Januvia® would receive 50mg once daily. The dose of Diamicron® to be used in the study (80mg per day initially and increasing to 320mg per day in successive steps) is consistent with the doses stated in the SPC for the marketed product. In the case of the development of a condition that was expected to continue indefinitely, the investigator referred, in a timely fashion, the research participant for appropriate treatment. In this case, the investigator ensured that an initial diagnosis had been made and that appropriate treatment of the condition had commenced. The sponsor monitored the progress of all clinical investigations being conducted. In case of any damage or injury occurring to a patient in association with the investigational medicinal product or their participation in the study, the sponsor had insurance which covered the liability of the sponsor, the investigator and other persons involved in the study in compliance with the laws of Ireland. All investigators were qualified and practicing physicians and were thus insured by the clinical indemnity scheme.
    Background therapy
    Topical or systemic treatment for psoriasis
    Evidence for comparator
    Sitagliptin, a DPP-4 inhibitor, is an oral glucose-lowering agent approved for the treatment of type 2 diabetes mellitus. DPP-4 inhibitors prevent the degradation of insulin secretagogues such as glucagon-like peptide-1 thereby ameliorating hyperglycaemia without causing hypoglycaemia. DPP-4 inhibition may have systemic anti-inflammatory effects and a reduction in serum C-reactive protein. This randomised controlled trial assessed the effects of the DPP-4 inhibitor sitagliptin and a comparator diabetes agent, the sulphonylurea, gliclazide, on psoriasis severity psychological morbidity, cardiovascular disease risk factor profiles and immune parameters.

    Recruitment
    Recruitment details
    Potentially eligible research participants were identified through a patient databases and review of healthcare records in St Vincent’s University Hospital and Adelaide and Meath Hospital. Participants were recruited by the investigators/qualified designee during clinic or by invitation letter. Consenting was done by PILs and consent forms.

    Pre-assignment
    Screening details
    Screening performed during screening visit. 89 candidates were assessed for eligibility of whom 68 did not meet inclusion criteria and 1 declined to participate.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    23 Jan 2014
    A substantial amendment to change the trial from an open label to a double blind trial was submitted to and approved by the regulatory authority the HPRA. On the advice of the sponsor representative and Co-ordinating Investigator for this study, it was decided the study should focus on the efficacy of the IMP; safety data would no longer be analysed as an endpoint. A secondary efficacy endpoint of ‘Change in psoriasis area and severity index after 32 weeks of treatment’ was added. This was omitted in error from the original protocol.We changed from Diamicron MR 30mg tablets to Diamicron 80mg tablets which are comparable as stated in the SmPC for Diamicron MR. The reason for changing the formulation was to avoid potentially costly and time consuming dissolution analysis which would be required if a modified release tablet rather than a normal release tablet was overencapsulated. These amendments were made prior to enrollment of participants.
    08 Jan 2015
    An amendment changed the inclusion criteria specifying that a potentially suitable participant should have a glycated haemoglobin (HbA1c) between 6.5% and 8.5% (48mmol/mol and 69mmol/mol) to between 6.5% and 9.5% (48mmol/mol and 80mmol/mol) to enhance recruitment. This amendment was made during the trial and approved by the HPRA.

    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.
    This study did not recruit the planned number of patients needed to achieve its primary end-point (n=40). Given this limitation, there are no significant differences in improvements in psoriasis severity between sitagliptin and gliclazide.
