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   43845   clinical trials with a EudraCT protocol, of which   7282   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 characterise the tolerability of Modufolin in Stage IV CRC patients in 1st or 2nd line treatment in terms of toxicity during eight (8) weeks of treatment with one (1) of four (4) dose levels of Modufolin in the treatment arms.
    Protection of trial subjects
    The study protocol and amendments were submitted to ethics committees and/or to competent authorities for approval before patients were recruited, in accordance with the International Council of Harmonisation guidelines, the applicable European Directives and local legal requirements. The study was conducted in compliance with the protocol, regulatory requirements, good clinical practice and the ethical principles of the latest revision of the Declaration of Helsinki as adopted by the World Medical Association. All patients received written and verbal information regarding the study, which emphasised that participation in the study was voluntary and that the patient could withdraw from the study at any time and for any reason. All patients were given the opportunity to ask questions about the study and were given sufficient time to decide whether to participate in the study. Before performing any study-related procedures, the informed consent form was signed and personally dated by the patient and by the person who conducted the informed consent discussion.

    Amendment
    08 Jul 2014
    Amendment to the study protocol and IB based on input from the Swedish regulatory authority MPA. Changes were made to the study rationale, design as well as safety evaluation and reporting.
    21 Jan 2015
    Inclusion of Denmark and Norway. Introduction om Arm #3 (Irinotecan treatment). Removal of arfolitixorin dose 120 mg/m2 in Treatment Arm #1. Addition of explorative endpoint tissue sample for gene expression.
    17 Jun 2015
    Introduced a sub-study, the Follow-up Study, which would allow the continued treatment with arfolitixorin in those patients who did not show either clinical or radiological signs of disease progression after completing the study treatment in the initial 8 week treatment (i.e., Main Study). Further adaptation of the method for assigning patients to treatment to ensure that patients deemed fit for at least one of the chemotherapies in the treatment arms could enrol even if unfit for the other treatment arms in the study. Changes in the eligibility criteria for enrolment in the Main Study, such as changes to align with the adaptation of the method for allocation of patients to treatments, and to allow patients in other than first line settings.
    22 Apr 2016
    Introduced new treatment cohorts with higher arfolitixorin doses (i.e., 120 and 240 mg/m2) with the aim to acquire information critical for the design of planned next clinical study with arfolitixorin in the intended indication. Adaptation of the requirements needed to ensure that data collected was satisfactory for a suitable assessment of the tolerability of arfolitixorin in the combination with the chemotherapies given. The assessment of dU levels was re-classified as an exploratory endpoint (previously secondary efficacy endpoint).
    03 Oct 2016
    Introduced a new chemotherapy infusion regimen and a treatment arm including bevacizumab. The primary endpoint was updated to clarify that, not only the number of patients who had their chemotherapy dose adjusted due to related toxicity, but also the actual number of dose adjustments made would be assessed. Greece was also included for recruitment of patients in several clinical sites. The eligibility criteria for enrolment in the Main Study were updated in alignment with introduction of the new treatment arms and applicable clinical practice. The contact information for the new Coordinating Investigator, as notified separately (15-Jun-2016), was updated.
    05 Jul 2017
    Introduced new treatment cohorts in Treatment Arm #5 leading to administration of up to three (3) doses of the IMP: 60 mg/m2, 120 mg/m2 and 240 mg/m2 instead of only receiving arfolitixorin at the SP2D.
    23 Nov 2017
    Up to 10 new patients were planned to be included in each of Treatment Arm #4 and #6, respectively. All new patients added received arfolitixorin at the SP2D. Addition of a tumour biomarker blood sample collection for patients in Treatment Arm #4 and #6, respectively. Addition of nine (9) patients at the SP2D in Treatment Arm #5.
    19 Jul 2018
    Included the expansion of Cohort #18 (Treatment Arm #4) and the cohort(s) in the Treatment Arm #6 with additional 10 patients in each treatment regimen, i.e. 20 new patients in the clinical study. With this amendment the Sponsor aimed to obtain more data on the safety, tolerability, and efficacy. Included the statement that the amended study protocol is in accordance with the then newly enforced General Data Protection Regulation (GDPR).
    22 Nov 2019
    Changes were made to the eligibility (exclusion criteria #2 and #16) for enrolment in the Main Study. Change to the secondary objective regarding evaluation of tumour response and disease progression.
