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 ).

    General information about the trial
    Main objective of the trial
    The primary objective is to evaluate the efficacy of FDA-277 combined with standard of care on reducing the SARS-CoV-2 viral load.
    Protection of trial subjects
    All patients could be treated for symptoms due to SARS-CoV-2 infection as per standard of care recommendation: • In mild clinical conditions: o Acetaminophen 500 mg 1-4 times daily for control of fever and as an analgesic. o Non-steroidal anti-inflammatory drugs in the doses indicated as per their fact sheet. o Symptomatic treatment. o Adequate hydration. • In moderate clinical conditions: o Only in the case of suspected bacterial co-infection/superinfection antibiotic treatment will be introduced with: o Amoxicillin/Clavulanic Acid 875 mg/125 mg every 8 hours for 7 days. o Alternatively, levofloxacin 500 mg every 12 hours on the first day and 500 mg every 24 hours for 4 days [thereafter]. o Symptomatic treatment. o Adequate hydration. o BRONCHODILATORS: If required, they were preferably administered in pressurized cartridge with individual holding chamber (spacer), to avoid aerosol generation: salbutamol, 100 mcg/inhalation plus Ipratropium Bromide 20 mcg/inhalation: 2 inhalations every 4-6 hours; inhaled corticosteroids: only used in patients with bronchial asthma or COPD. o SYSTEMIC CORTICOSTEROIDS: Use in outpatients without the need for oxygen therapy is not recommended. Its use could be counterproductive in patients who do not require oxygen therapy. They were exclusively recommended at low doses in patients requiring oxygen therapy. o ANTITHROMBOTIC PROPHYLAXIS: Low molecular weight heparin at prophylactic doses for patients immobilized or with risk factors: Enoxaparin 4,000 IU (40 mg) subcutaneously once daily. If creatinine clearance is observed at 15-30 mL/min, enoxaparin 2000 IU (20 mg) could be administered subcutaneously once daily. Enoxaparin was not recommended if creatinine clearance was less than 15 mL/min. Bemiparin could be used as an alternative. In all cases, home isolation was required, according to the rules applicable at the time of study

    Reporting group description
    		 This analysis population consist of all patients included in the “all randomized patient population” who have not violated the protocol so that it may affect the assessment of the effect of the study drug on the primary endpoint, ie, without major protocol deviations. The criteria for identifying major protocol deviations were reviewed prior to the start of the analysis and unblinding of treatment and was described in the analysis plan. 180 patients were randomized. Seven patients were excluded from the data set due to protocol deviation (placebo group 4; domperidone gropu 3). The set population was 173 patients.

    		 Change in ORF1ab viral load (Ct) Day4-Baseline
    End point description
    Baseline – 4 days difference ORF1ab RT-PCR number of cycles. The viral load was estimated by the number of cycles (Cts) until detection of three specific genes of the SARS-Cov-2 pathogenic viral strain, using the TaqPath COVID-19 CE-IVD RT-PCR Kit (Thermofisher, USA), which detects three highly conserved regions of the RNA SARS-CoV-2 virus along with an internal positive control (MS2-IPC) in a single PCR reaction: genes encoding ORF1ab, N Protein, S Protein, with a sensitivity of >99% and Specificity of 99.5%. For the correct interpretation of data: an increase in the number of amplified cycles means a better result as a reduction in the viral load. So, the difference D4-D0 positive means an improvement, better as the figure is higher. If the difference D4-D0 is negative, it means a worsening.
