Summary:

      This clinical study was designed to assess the efficacy and safety of DFV890 for the
      treatment of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infected patients
      with coronavirus disease 2019 (COVID-19) pneumonia and impaired respiratory function.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Male and female patients aged 18-80 years inclusive at screening.

          -  Clinically diagnosed with the SARS-CoV-2 virus by polymerase chain reaction (PCR) or
             by other approved diagnostic methodology within 7 days prior to randomization.

          -  Hospitalized with COVID-19-induced pneumonia evidenced by chest X-ray, computed
             tomography scan (CT scan) or magnetic resonance scan (MR scan), taken within 5 days
             prior to randomization (within 24 hours in patients in the Netherlands).

          -  Impaired respiratory function, defined as peripheral oxygen saturation (SpO2) ≤93% on
             room air or partial pressure of oxygen (PaO2) / fraction of inspired oxygen (FiO2)
             <300 millimeter of mercury (mmHg) at screening. For cities located at altitudes
             greater than 2500 m above sea level, these will be substituted with SpO2 <90% and
             PaO2/FiO2 <250 mmHg.

          -  APACHE II score of ≥10 at screening.

          -  C-reactive protein (CRP) ≥20 mg/L and/or ferritin level ≥600 μg/L at screening.

          -  Body mass index of ≥18 to <40kg/m2 at screening.

        Exclusion Criteria:

          -  Suspected active or chronic bacterial (including Mycobacterium tuberculosis), fungal,
             viral, or other infection (besides SARS-CoV-2).

          -  In the opinion of the investigator, progression to death is imminent and inevitable
             within the next 24 hours, irrespective of the provision of treatment.

          -  Intubated prior to randomization.

          -  Previous treatment with anti-rejection and immunomodulatory drugs within the past 2
             weeks, or within the past 30 days or 5 half-lives (whichever is the longer) for
             immunomodulatory therapeutic antibodies or prohibited drugs, with the exception of
             hydroxychloroquine, chloroquine or corticosteroids:

        For COVID-19 infection, ongoing corticosteroid treatment is permitted at doses as per local
        SoC.For non-COVID-19 disorders, ongoing corticosteroid treatment is permitted at doses up
        to and including prednisolone 10 mg daily or equivalent.

        In patients in the Netherlands only, the use of hydroxychloroquine and/or chloroquine in
        the past 2 weeks are exclusionary.

          -  Serum alanine transaminase (ALT) or aspartate transaminase (AST) >5 times upper limit
             of normal detected within 24 hours at screening or at baseline (according to local
             laboratory reference ranges) or other evidence if severe hepatic impairment
             (Child-Pugh Class C).

          -  Absolute peripheral blood neutrophil count of ≤1000/mm3.

          -  Estimated GFR (eGFR) ≤30 mL/min/1.73m2 (based on CKD-EPI formula).

          -  Patients currently being treated with drugs known to be strong or moderate inducers of
             isoenzyme CYP2C9 and/or strong inhibitors of CYP2C9 and/or strong inducers of
             cytochrome P450, family 3, subfamily A (CYP3A) and the treatment cannot be
             discontinued or switched to a different medication prior to starting study treatment.

          -  Patients with innate or acquired immunodeficiencies.

          -  Patients who have undergone solid organ or stem cell transplantation.
