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 outcome is the efficacy of the intervention ascertained by the DARC Count, which is the number of apoptosing retinal cells visualised 4 hours after the ANX776 injection in patients with Glaucoma, Age-related Macular Degeneration (AMD), Optic Neuritis (ON), Down's syndrome and in Healthy volunteers.
    Protection of trial subjects
    The trial was conducted in compliance with the approved protocol, UCL CCTU Standard Operating Procedures, the Declaration of Helsinki (2008), the principles of Good Clinical Practice (GCP) as laid down by the Commission Directive 2005/28/EC with implementation in national legislation in the UK by Statutory Instrument 2004/1031 and subsequent amendments, the Human Tissue (Quality and Safety for Human Application) Regulations 2007, the UK Data Protection Act, and the National Health Service (NHS) Research Governance Framework for Health and Social Care (RGF). The following protocol pre-defined reasons for stopping the trial early for a participant were in place: unacceptable toxicity or adverse event; inter-current illness that prevents further treatment; any change in the participant’s condition that in the clinician’s opinion justifies the discontinuation of the trial. Participants were under no obligation to enter the trial and they could withdraw consent or assent / withdrawal of consent by the legal representative for Down’s syndrome participants at any time during the trial, without having to give a reason, and without their clinical care being affected.

    Recruitment
    Recruitment details
    Participants for the glaucoma, AMD, optic neuritis and healthy volunteer groups were recruited through designated participant identification centres and REC approved advertisements. Participants in the Down’s syndrome arm were recruited from two pre-existing cohorts in the Cambridge Intellectual and Developmental Disabilities Research Group.

    Pre-assignment
    Screening details
    Eligibility criteria for all groups were those aged 18 years or above, with clear optical media in the studied eye, refractive error not higher than spherical equivalent of 10 D and women of childbearing potential identified as not pregnant.

    Primary outcome
    End point description
    Raw DARC counts are taken from imaging of each eligible eye using an automated process built on an algorithm which was developed blind to disease group to ensure an objective measure which is comparable across groups. The cSLO images were background subtracted and standardised before a template matching approach was applied using a 50*50 pixel ‘ideal spot’ template to identify spot candidates. Once identified, spot candidates will be extracted from each cSLO image and spot morphology recorded. An exploratory technique was undertaken to validate an algorithm for differentiating ‘true’ DARC spots amongst candidates. The resulting DARC spots were summed for each eye to yield a ‘weighted’ DARC count. Analysis will be repeated using the ‘weighted’ DARC count produced using the algorithm as exploratory outcome.

    End point title
    Exploratory analysis - weighted DARC counts [16]
    End point description
    An exploratory technique was undertaken to validate an algorithm for differentiating ‘true’ DARC spots amongst candidates. Spot candidate populations were gated to exclude non-DARC spot objects and artefacts based on spot area (> 10 pixels and < 1000 pixels in size), standard deviation (standardised intensity units > 0.5) and solidity (measure of roundness/ overall concavity) < 0.75). The resulting DARC spots were summed for each eye to yield a ‘weighted’ DARC count.

    Notes
    [16] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: At present, data are available for the Glaucoma participants and Healthy volunteers only. The same technique will be used to obtain the weighted DARC counts in all the other groups.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    30 Nov 2016
    Protocol updated to v3.0 with the following: removal of the Down’s syndrome group and a reduction of the sample size accordingly by 20; general participant exclusion criterion in relation to contraception and pregnancy amended for consistency; inclusion of a table of additional pre-clinical data for DARC; clarifications throughout.
    03 Jan 2017
    Extension of the expiry date of the IMP (ANX776) until 30 June 2017 based on new stability testing data. Updated IMPD.
    20 Apr 2017
    Protocol updated to v4.0 with the following: re-inclusion of a subgroup of 20 participants with Down’s syndrome. This subgroup was originally approved by the MHRA but was removed as the REC requested further scientific and ethical rationale for the inclusion of this subgroup. The rationale is provided in the protocol.
    01 Jun 2017
    Details: Protocol updated to v9.0 with the following: REC requested changes in relation to the inclusion of the participants with Down’s syndrome subgroup; general inclusion criteria edited to remove requirement for best corrected visual acuity equal to 6/24 or better at qualification and to state women of childbearing potential must agree to a pregnancy test instead of consent; removal of the exclusion criteria for age-related macular degeneration subgroup relating to the presence of ocular conditions with increased risk of choroidal neovascularisation. Only those with choroidal neovascularisation will be excluded; removal of the single exclusion criteria for the optic neuritis subgroup; clarifications throughout.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
