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   44343   clinical trials with a EudraCT protocol, of which   7372   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 is to study safety and tolerability of IBsolvMIR® in comparison to Heparin, in combination with standard immunosuppressive therapy in islet transplantation.
    Protection of trial subjects
    Transplantations performed according to Nordic Network of Clinical Islet Transplantation SOPs. These include close monitoring of the vital signs of the patient, including ultrasound examination of possible bleeding after transplantation. DMC safety meetings were held once the 2 first patients received the IBsolvMIR treatment. Each time the DMC held a safety meeting, the data (safety data from start of IMP/comparator treatment until at least the follow-up on Day 7), needed to be reviewed by the DMC before the next patient could be included. The DMC monitored SAEs on a regular basis. When an SAE occurred, the members of the DMC were notified via e-mail/eCRF alert. The DMC chairman then considered the need for an additional DMC meeting. In case of a suspected unexpected serious adverse reaction (SUSAR) related to IBsolvMIR, the DMC chairman always scheduled an extra meeting before the study could commence.

    Interruptions (globally)

    Were there any global interruptions to the trial? Yes
    Date
    Interruption
    Restart date
    05 Apr 2022
    As planned according to the DMC charter, inclusion was paused after two patients were treated until the DMC-meeting was held. The DMC concluded there was no emerging safety concerns and recommend that the study proceed according to the current protocol.

    SAE Renal impairment (Seriousness criterion: Prolonged hospitalisation); No ad hoc DMC meeting according to chairman. Rational for the decision: Acute rise in creatinine was secondary to tacrolimus toxicity (levels 16 and 15) compounded by spironolactone exposure. Spironolactone stopped. Creatinine now recovered. Does not seem at all related to study drug. No further action required.

    SAE hepatic bleeding; inclusion interruption until DMC meeting. DMC recommendation: The DMC voting members recommend the sponsor to advise the participating centres to implement the method using avitene powder for tract closure if practically possible. The DMC members do not recommend the sponsor to halt the trial if such method is not implemented at all centres but consider the risk of a definitive discontinuation of the trial if another bleeding event occurs within the context of such a small trial.

    SAE hepatic bleeding; The DMC conclude that it is difficult to definitively assign the causality of the current event of hepatic bleeding to the trial treatment IBsolvMIR. However, the current event is the second hepatic bleeding in the trial treatment group consisting of in total only six patients. Given the anticoagulating properties of the study treatment, it is likely but not proven that IBSolvMIR contributed to the severity of the event. The DMC can therefore not support a continuation of the trial under the current protocol and recommend the sponsor to discontinue the trial. If the protocol is amended to mitigate the risk of bleeding events, the Sponsor/group of participating investigators are encouraged to seek the opinion of the DMC for the sufficiency of these safety measures. 13 May 2024, the sponsor decided that the protocol would not be amended to mitigate the risk of bleeding and that the causality with study treatment would not be further investigated. The patient enrolment difficulties contributed to the decision.

    Limitations and caveats

    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Since the inter-individual variation was high, the sample size small, and the control group only consisted of a single patient, no firm conclusions can be drawn based on biomarker data.
