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   43227   clinical trials with a EudraCT protocol, of which   7153   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    The objectives of the study are:
    1)To observe the long term safety and efficacy of Coversin over periods in excess of 6 months
    2)To assess the long term patient acceptability of Coversin using the EORTC QLQ-C30 and the EQ-5D-5L instruments
    3)To observe the changes, if any, in the production of anti-drug antibodies (ADA) and whether such antibodies are, or become, neutralising
    4)To assess the effects, if any, on any changes in formulation or drug delivery that may be introduced during the study period
    E.2.2Secondary objectives of the trial
    Not applicable
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1)Patients 18 years and above successfully treated with Coversin under other Akari clinical trial protocols and wish to remain on Coversin at the conclusion of that trial.
    2)On a stable dose of Coversin for at least 2 weeks prior to entering the AK581 long term safety and efficacy surveillance study.
    3)Evidence of sustained total complement inhibition by CH50 assay.
    4)An appropriately qualified clinician is willing to keep the patient under observation and treatment whilst on Coversin and to be named as an investigator in this trial.
    5)Willing to give informed consent .
    E.4Principal exclusion criteria
    1)Patient is unwilling to continue on Coversin.
    2)Patient is unwilling to complete the Quaity of Life instruments and diary card.
    3)Evidence of active meningococcal infection(swab testing not required).
    4)On concurrent treatment with another complement inhibitor.
    5)Any other reason for which, in the opinion of the investigator, it would not be in the interests of the patient to remain on Coversin
    E.5 End points
    E.5.1Primary end point(s)
    Primary Efficacy Endpoints:
    Long term safety of Coversin as assessed by SAEs, AEs, vital signs, immunogenicity assessments, results of appropriate standard laboratory tests (clinical chemistry, haematology, coagulation, urinalysis, and ADA).
    E.5.1.1Timepoint(s) of evaluation of this end point
    3, 6, 9, 12 months and every 6 monthly thereafter
    E.5.2Secondary end point(s)
    Secondary Efficacy Endpoints:
    1)Thrombotic and haemolytic event free survival at 3, 6, 9 and 12months and 6 monthly thereafter from the start of the long term safety and efficacy study.
    2)Reduction in requirement for blood or blood product transfusion compared to pre-Coversin treatment over a similar period if data are available (for complement inhibitor naïve patients).
    3)Reduction in requirement for blood or blood product transfusion compared to pre-Coversin treatment over a similar period (for patients who received treatment with another complement inhibitor before switching to Coversin).
    4)Non-inferiority in requirement for blood or blood product transfusion compared to pre-Coversin treatment over a similar period for patients who received treatment with another complement inhibitor before switching to Coversin. For example there should be no increase in transfusion requests for 3 months post-switch compared to 3 months pre-switch.
    5)Quality of life using the EORTC QLQ-C30 and the EQ-5D-5L instruments at 3, 6, 9 and12 months and at each clinic visit thereafter.
