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   43973   clinical trials with a EudraCT protocol, of which   7311   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.

    • To assess the general safety and tolerability of E4 compared to placebo when administered to patients with confirmed SARS-CoV-2 infection who are hospitalized with moderate COVID-19 (i.e. not on high flow oxygen or mechanical ventilation).
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Postmenopausal women who have not used HRT (including oral, transdermal, topical, or vaginal preparations) within 1 year prior to study start. Menopause is defined as women who have at least 12 months of spontaneous amenorrhea without another medical cause.

    2. Patients with SARS-CoV-2 infection confirmed by a nationally accepted RT-PCR and moderate COVID-19.
    Patients with a strong clinical suspicion of moderate COVID-19 and a positive point-of-care test for viral infection can also be entered while the result of a nationally accepted RT-PCR assay is awaited; if the RT-PCR assay result is negative, the treatment must be stopped and the patient must be discontinued from the study.

    The definition of moderate COVID-19 is:
    i. Positive testing by standard RT-PCR assay.
    ii. Symptoms of moderate illness with COVID-19, which could include any symptom of mild illness (including fever, cough, anosmia, dysgeusia, sore throat, malaise, headache, muscle pain, gastrointestinal symptoms) or shortness of breath with exertion.
    iii. Clinical signs suggestive of moderate illness with COVID-19, such as respiratory rate ≥20 breaths per minute, heart rate ≥90 beats per minute.
    iv. No clinical signs indicative of severe or critical illness (i.e. need for ventilation or ICU admission).
    3. Hospitalized.
    4. Clinical Frailty Score ≤5.
    5. World Health Organization (WHO) Ordinal Scale for Clinical Improvement score of 4 or 5.
    6. Able to provide IC.
    7. Able to comply with the study procedures as defined in the protocol.
    E.4Principal exclusion criteria
    1. Males currently receiving estrogen-based hormonal therapy.
    2. Current participation in another interventional clinical trial.

    9. Presence or history (including suspected diagnosis) of estrogen-sensitive tumors (e.g endometrial cancer)
    10. Patients with endometrial hyperplasia.
    11. Patients with severe hypoxemia at risk of endotracheal intubation.
    12. Immunocompromised patients
    13. History of stroke, acute coronary syndromes, or angina pectoris.
    14. Presence or history of arterial or venous thrombosis/
    thromboembolia (including deep vein thrombosis and pulmonary
    15. Patients with any condition, including findings in the patients' medical history or in the screening study assessments that in the opinion of the Investigator, constitute a risk or a contraindication for the participation of the patient into the study or that could interfere with the study objectives, conduct or evaluation, including patients with suspected genital cancer or suspected breast cancer and patients with increased risk of development of venous thrombosis/ thromboembolia for reasons other than COVID 19 disease.
    16. Use of zanamivir or oseltamivir within 1 week prior to randomization.
    17. Patients who have received prior investigational or off-label agents for COVID-19. (Note: use of antivirals and corticosteroids is allowed if part of SoC).

    E.5 End points
    E.5.1Primary end point(s)
    The primary endpoint for this trial is the improvement in COVID-19 between the placebo and E4 groups measured by the percentage of patients recovered at Day 28. Recovery will be defined as reaching a score of ≤3 on the WHO (0-10) scale.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Day 28 (±2 days) or 7 days (±2 days) after the last dose of study drug if treatment is stopped prior to Day 21.
    E.5.2Secondary end point(s)
    1. The percentage of patients reaching a score of WHO ordinal scales (0-10) of ≥6 at 28 days.
    2. The improvement in time to recovery between the placebo and E4 groups (≤3 on the WHO (0-10) scale).
    3. Changes in viral load between the E4 and placebo groups.
    E.5.2.1Timepoint(s) of evaluation of this end point
    • WHO Ordinal Scale for Clinical Improvement score will be recorded daily at the same time each day (±3 hours) at Screening, on Treatment Days 1−21 whilst the patient is hospitalized and at the End of Treatment and End of Study visits.
    • Oropharyngeal swabs for viral load assessment will be taken on Treatment Day 1 (immediately before taking the dose of study drug), on Days 3, 7, and 14 when the patient is in hospital, and at the End of Treatment visit.
