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   44334   clinical trials with a EudraCT protocol, of which   7366   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 ).

    Cardiac index (CI) is a hemodynamic parameter that relates the cardiac output (CO) from left ventricle in one minute to body surface area (BSA), thus relating heart performance to the body size of the subject. It was measured by RHC. Full analysis set included all randomised subjects, irrespective of whether they received any study treatment.

    		 Part A: Change in CI Measured by RHC at 0.5, 1, 2, 3, 4 and 5 Hours During 6 Hour IV Infusion
    End point description
    CI is a hemodynamic parameter that relates the CO from left ventricle in one minute to BSA, thus relating heart performance to the body size of the subject. It was measured by RHC. Full analysis set included all randomised subjects, irrespective of whether they received any study treatment.

    End point description
    PCWP estimated the left atrial pressure and was the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch. PCWP was assessed by 2 successive measurements at least 10 minutes apart. RAP is the blood pressure in the right atrium of the heart. Change in PCWP, RAP, PAS/PAD at 0.5, 1, 2, 3, 4, 5 and 6 hours during the 6-hour IV infusion was reported in this endpoint. All the parameters were measured by RHC. Full analysis set included all randomised subjects, irrespective of whether they received any study treatment. All subjects reported under 'Number of Subjects Analysed' contributed data to the table but may not have evaluable data for every row. Here, ‘Number of Subjects Analysed’ signifies number of subjects evaluable for this endpoint.

    		 Part A: Change in Pulmonary Vascular Resistance (PVR) Measured by RHC at 0.5, 1, 2, 3, 4, 5 and 6 Hours
    End point description
    PVR is the resistance against blood flow from the pulmonary artery to the left atrium. Change in PVR measured by RHC at 0.5, 1, 2, 3, 4, 5 and 6 hours during the 6 hour IV infusion was reported in this endpoint. Full analysis set included all randomised subjects, irrespective of whether they received any study treatment. All subjects reported under 'Number of Subjects Analysed' contributed data to the table but may not have evaluable data for every row. Here, ‘Number of Subjects Analysed’ signifies number of subjects evaluable for this endpoint.

    End point description
    SBP, DBP and MAP were measured in a supine or seated position after subject had at least 5 minutes of rest. MAP is the average pressure of the blood circulating through a subject's arteries during the cardiac cycle. MAP was derived by using the following formula: DBP + 1/3(SBP-DBP). Full analysis set included all randomised subjects, irrespective of whether they received any study treatment.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    09 Mar 2021
    Updates to the exclusion criteria. Prolonged the screening period for Part A to 21 days prior to and including Day 1 (Days - 21 to 1).
    19 Oct 2021
    Updates to provide additional guidance for IV administration and interruption procedures, and selection and monitoring of the infusion site. For exclusion criteria, new criterion was added for conditions that in the opinion of the Investigator may have increased the risk of infusion site reactions (ISRs) and/or compromised subject assessment of the ISRs. Revised reasons in which the study must have been terminated and those that may have terminated the study for clarity. Added safety related criteria for stopping study treatment. Provided further clarification for dose escalation stopping criteria.
    26 Apr 2022
    Modified eligibility criteria that were not safety related. Added organic-anion-transporting polypeptide (OATP) genotype assessment to the exploratory objectives.

    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 was terminated early due to a business decision that was not due to any safety concerns. The number of subjects was smaller than originally planned and only summary statistics were therefore generated for primary and secondary endpoints.
