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   43865   clinical trials with a EudraCT protocol, of which   7286   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.

    General information about the trial
    Main objective of the trial
    To demonstrate that the oral therapy with Cloricromene hydrochloride (Proendotel ®) capsules 100m admistered 3 time daily via oral route for 24 months, is superior to placebo in the arrest of progression of non-proliferative retinopathy in patients with diabetes of type I and II (insulin or non-insulin dependent)
    Protection of trial subjects
    The protocol complied with the ethical principles for medical research and recommendations adopted by the 18th World Medical Assembly (Helsinki, 1964) and its amendments (52nd WMA General Assembly, Edinburgh, Scotland, October 2000, and clarifications by the WMA General Assembly, Washington 2002). The protocol also complied with the laws and regulations applicable in Italy. This study was conducted according to globally accepted standards of good clinical practice ed in the ICH E6 Guideline for Good Clinical Practice, 1 May 1996.

    Pre-assignment
    Screening details
    Patients underwent an initial screening visit in which candidate patients for the study were selected, a 2- to 7-day run-in period, where patients had any non-permitted medications withdrawn prior to study entry and study entry criteria were checked, and a 24-month treatment period with the assigned study drug (active treatment).

    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: Due to the low sample size reached and consequently the lack of statistical power, the statistical methods were modified to descriptive analysis for all endpoints and safety data.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    02 Nov 2004
    Deletion of fluorescein angiography at visit 3 (month 6); Fluorescein angiography to be performed only in the most seriously affected eye, in case of bilateral affection; Centralized reading of fundus color photography, fluorescein angiography and OCT at AIBILI (Association for Innovation and Biomedical research on Light and Image) – Coimbra (Portugal); Best corrected visual acuity measured in both eyes at visit 1, and only in the affected eye in case of monolateral affection; demographic data to be collected in the run-in period Carton boxes were provided containing 40 blisters with 15 capsules each, instead of 60 blisters with 10 capsules each Specification that the interim analysis would be done “to assess consistency of progression rates in the Chloricromene and placebo groups with planned estimations”
    27 Sep 2007
    Change in selection criteria, to facilitate patients’ enrolment: exclusion criterion “history of focal photocoagulation for diabetic macular edema in the study eye” modified as follows: “history of photocoagulation for diabetic macular edema in the study eye except focal photocoagulation at least 6 months before”. This change had no impact on the primary end-point “progression of retinopathy”; Prolongation of the study timelines with study end postponed until December 2010, due to slow enrolment rate
    30 Nov 2008
    Anticipation of closure in study activities, due to slow enrolment rate, with study end established in May 2009.

    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.
    Due to the low sample size reached and consequently the lack of statistical power, the statistical methods were modified to descriptive analysis for all endpoints and safety data.
