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   43396   clinical trials with a EudraCT protocol, of which   7179   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.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    A patient will be eligible to participate in this study if ALL the following criteria are met:
    1. Adult (≥ 18 years old) men or women hospitalized or not hospitalized, diagnosed
    for SARS-CoV-2 infection by PCR (within 48 hours prior to randomization), with at least one associated risk factor. Considered risk factors are:
    • Age ≥ 65 years
    • Obesity defined as BMI ≥ 30
    • Recent history of uncontrolled High Blood Pressure (SBP > 150 mm Hg & DBP >100 mm Hg) according to investigator
    • Treated diabetes (type I or II)
    • History of ischemic cardiovascular disease
    2. Symptomatic patients must present at least 1 of the following symptoms at enrollment: fever or perceived fever (for more than 24 hours, headache, sore throat, dry cough, fatigue, chest pain or choking sensation (with no associated respiratory distress), myalgia, anosmia, ageusia or gastro-intestinal symptoms.
    3. Patients with pulse oximetry arterial saturation (SpO2) ≥ 92 % on room air at
    4. Patients with the following hematological and biochemical laboratory parameters obtained within 7 days prior to D0:
    • Hemoglobin > 9.0 g dL-1
    • Absolute Neutrophil Count ≥ 1000 mm-3;
    • Platelets ≥ 100,000 mm-3;
    • Creatinine clearance ≥ 50 mL min-1 by the Cockcroft-Gault formula
    • Total serum bilirubin < 2 x ULN
    • Alkaline phosphatase< 2 x ULN, AST (SGOT) and ALT (SGPT) < 3 x ULN;
    5. Women of childbearing potential and men receiving the study treatment and their partners must agree to use a highly effective contraceptive method during the study and for 6 months (180 days) after end of study or early termination. Contraception should be in place at least 2 weeks prior to enrolment. 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 patient. In each case of delayed menstrual period (over one month between menstruation) confirmation of absence of pregnancy is required. This recommendation also applies to WOCBP with infrequent or irregular menstrual cycle. Female and male patients must not be planning pregnancy during the trial and for 6 months post completion of their participation in the trial. In addition, male patients should use condom during the trial and for 6 months (180 days) post completion of their participation in the study. Male patients 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 sterilisation 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. However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient. Finally a man is considered fertile after puberty unless permanently sterile by bilateral orchidectomy.
    6. Patients must understand, sign and date the written voluntary informed consent form at the visit prior to any protocol-specific procedures.
    7. Patients able and willing to comply with study visits and procedures as per protocol.
    8. Patients should be affiliated to a social security regimen (for French sites only).
    E.4Principal exclusion criteria
    Patients who meet any of the following exclusion criteria will be excluded from the study:
    1. Patients with moderate or severe acute respiratory failure or requiring non-invasive ventilation or oxygen or with SpO2 < 92% or tachypnea (respiratory rate ≥ 30 breaths/min).
    2. Patients treated with immunosuppressors and/or immunomodulators (cf. Appendix #2).
    3. Engrafted patients (organ and/or hematopoietic stem cells).
    4. Patients with uncontrolled auto-immune disease.
    5. Patients with known or suspected active (i.e. not controlled) bacterial, viral
    (excluding COVID-19) or fungal infections.
    6. Patients with preexisting, severe and not controlled organ failure.
    7. History or active malignancy requiring chemotherapy or radiation therapy (excluding 2 years disease free survivor patients).
    8. Pregnant or breast-feeding women.
    9. Illicit drug or alcohol abuse or dependence that may compromise the patient's safety or adherence to the study protocol.
    10. Use of any investigational or non-registered product within 3 months or within 5 half-lives preceding baseline, whichever is longer.
    11. Hypersensitivity to ABX464 and/or its excipients.
    12. Any condition, which in the opinion of the investigator, could compromise the patient's safety or adherence to the study protocol.
