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   44334   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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.1.1.1Medical condition in easily understood language
    In Ulcerative Colitis the lining of the colon becomes inflamed and develops tiny open sores that produce pus and mucous. This causes abdominal discomfort and frequent emptying of the colon (diarrhoea)

    E.2 Objective of the trial
    E.2.1Main objective of the trial

    E.2.2Secondary objectives of the trial
    The secondary objectives are:
    1. To evaluate the long-term effect of ABX464 on clinical remission;
    2. To evaluate the long-term effect of ABX464 on endoscopic remission;
    3. To evaluate the long-term effect of ABX464 on clinical response;
    4. To evaluate the long-term effect of ABX464 on endoscopic improvement;
    5. To evaluate the long-term effect of ABX464 on inflammatory markers (C-reactive protein (CRP), calprotectin);
    6. To evaluate the safety profile of ABX464;
    7. To evaluate the effect of ABX464 on miR-124 expression in total blood at every timepoint defined in the schedule of assessment.

    Echocardiography objective:
    8. To evaluate the effect of ABX464 on cardiac function as assessed through echocardiograms.


    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Subjects who previously completed the ABX464-102 or ABX464-104 clinical studies;
    2. Subjects should be in endoscopic improvement with a rectal bleeding sub-score = 0 point at the end of treatment period in the previous study (ABX464-102 or ABX464-104). Endoscopic improvement is defined as: a Mayo endoscopic sub score of ≤1 ;
    3. Subjects able and willing to comply with study visits and procedures;
    4. Subjects must understand, sign and date the written voluntary informed consent form at the visit prior to any protocol-specific procedures;
    5. Women of childbearing potential and men receiving the study treatment and their partners must agree to continue a highly effective contraceptive method during the study and for 6 months (180 days) after end of study or early termination. Women must be surgically sterile or if of childbearing potential must use a highly effective contraceptive method. Women of childbearing potential (WOCBP) will enter the study after confirmed menstrual period and a negative pregnancy test. Highly effective methods of contraception include true abstinence, intrauterine device (IUD) or hormonal contraception aiming at inhibition of ovulation, intrauterine hormone releasing system, bilateral tubal ligation, vasectomized partner. True abstinence is defined when this is in line with the preferred and usual lifestyle of the subject. In each case of delayed menstrual period (over one month between menstruations) confirmation of absence of pregnancy is required. This recommendation also applies to WOCBP with infrequent or irregular menstrual cycle. Female and male subjects must not be planning pregnancy during the trial and for 6 months post completion of their participation in the trial. In addition, male subjects should use condom during the trial and for 6 months (180 days) post completion of their participation in the study. Male subjects must not donate sperm as long as contraception is required. For the purpose of this protocol, a woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. Finally, a man is considered fertile after puberty unless permanently sterile by bilateral orchidectomy;
    6. Subjects should be affiliated to a social security regimen (for French sites only).
    E.4Principal exclusion criteria
    1. Subjects who have developed any major illness/condition or evidence of an unstable clinical condition (except UC) that, in the investigator's judgment, will substantially increase the risk to the participant if he or she participates in the study;
    2. Subjects with any other severe acute or chronic medical or psychiatric condition or laboratory or electrocardiogram (ECG) abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study;
    3. Subjects who are participating or plan to participate in other investigational studies (other than induction study) during the study.
