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   44335   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 ).

    General information about the trial
    Main objective of the trial
    To demonstrate that KSI-301 5 mg is non-inferior to aflibercept 2 mg with respect to mean change in best corrected visual acuity (BCVA) from Day 1 to Year 1 (average of Weeks 48 and 52).
    Protection of trial subjects
    The study followed the ethical principles derived from the Declaration of Helsinki and the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines. All local regulatory requirements pertinent to safety of trial subjects were followed during the conduct of the trial. At the Investigator's discretion, treatment with pan-retinal photocoagulation laser.

    Recruitment
    Recruitment details
    Participants were recruited based on physician referral at 75 medical centers between September 2020 and January 2022. The first participant was enrolled on 30 September 2020 and the last on 31 January 2022.

    Pre-assignment
    Screening details
    Of 689 screened participants, 459 met eligibility criteria and were randomized to treatment. Two randomized subjects in KSI-301 arm never received treatment, so do not have reason for not completing treatment. Each participant contributed only one study eye to this study.

    Blinding implementation details
    For masking purposes, sham injections will be administered at every monthly visit if an active treatment is not administered. To preserve masking, two investigators are required for this study. The masked Investigator will be responsible for the examinations and safety assessments. The unmasked Investigator will perform the injections and post-treatment assessments.

    Mean Change in BCVA
    End point description
    Mean change in best-corrected visual acuity (BCVA) from baseline to the average of Weeks 60 and 64 (using Early Treatment Diabetic Retinopathy Study (ETDRS) Letters). Best Corrected Visual Acuity (BCVA) was measured on the Early Treatment Diabetic Retinopathy Study (ETDRS) chart at a starting distance of 4 meters. The BCVA letter score ranges from 0 to 100 (best score), and a gain in BCVA letter score from baseline indicates an improvement in visual acuity.

    Adverse event reporting additional description
    One subject randomized to KSI-301 treatment arm received incorrect treatment of Aflibercept, so was included in the Aflibercept treatment arm for safety analyses. Therefore, for adverse event reporting, there are 228 subjects in KSI-301 treatment arm and 229 subjects in Aflibercept treatment arm.

    Date
    Amendment
    15 Mar 2022
    Changes from Version 1.0 (original protocol) include the following: •The timing for evaluation of the primary objective was extended by 12weeks, from the average of Weeks 48 and 52 to the average of Weeks60 and 64. •The disease activity criteria were adjusted and simplified to remove subjectivity and allow for more uniform application of the criteria across all study subjects, as well as to account for patients with persistent retinal oedema that is not worsening.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
