Here, hospital discharge can be considered when World Health Organization (WHO) Ordinal Scale for Clinical Improvement (OSCI) score of 2 (limitation of activities) or below, with no rebound at subsequent assessments. Improvement in clinical status is based on the 9-point OSCI score. The score ranges from 0 to 8, where lower score of 0 represents no clinical or virological evidence of infection and higher score of 8 represents death.
  • Time to recovery [ Time Frame: Day 1 until Day 28 ]
    To evaluate recovery in patients with moderate COVID-19 after administration of SNG001 compared to placebo by time to recovery. Here, recovery is defined as the WHO OSCI score of 1 (no limitation of activities) or below, with no rebound at subsequent assessments. Improvement in clinical status is based on the 9-point OSCI score. The score ranges from 0 to 8, where lower score of 0 represents no clinical or virological evidence of infection and higher score of 8 represents death.

Based on responses on above statements, scoring will be done and scores ranges from 0 to 4, where 0 represents not at all bothered by any of the above problems and 4 indicates very much bothered every day by any of the above problems. Higher scores indicated worse outcome.

Based on responses on questionnaire, scoring will be done and scores ranges from 0 to 4, where 0 represents not at all bothered by any of the above problems and 4 indicates nearly bothered every day by any of the above problems. Higher scores indicated worse outcome.
  • Number of patients with long-COVID-19 symptoms based on Brief Pain Inventory (Short Form) [ Time Frame: Day 15, Day 28, Day 60 and Day 90 ]
    Assessment of long-COVID-19 symptoms based on brief pain inventory form.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Admitted to hospital due to the severity of their COVID-19
  • Positive virus test for SARS-CoV-2 using a validated molecular assay or antigen assay. Patients who had a positive virus test for SARS-CoV-2 prior to hospitalisation will be randomised no later than 48 hours after hospital admission. If the virus test is performed more than 96 hours prior to hospitalisation, the test will have to be repeated in the hospital prior to randomisation. Only patients whose repeated virus test is positive will be randomised, no later than 48 hours after confirmation of SARS-CoV-2 infection. Patients who had their first positive virus test for SARS-CoV-2 after hospitalisation will be randomised no later than 48 hours after confirmation of SARS-CoV-2 infection
  • Require oxygen therapy via nasal prongs or mask (WHO OSCI score of 4)
  • Provided informed consent
  • Female patients must be ≥1 year post-menopausal, surgically sterile, or using a protocol defined highly effective method of contraception
  • Women of child bearing potential should have been stable on their chosen method of birth control for a minimum of 3 months before entering the trial and should continue with birth control for 1 month after the last dose of inhaled interferon-β (IFN-β1a)/matching placebo. In addition to the highly effective method of contraception (except for the practice of total sexual abstinence), a condom (in United Kingdom with spermicides) should be used by the male partner for sexual intercourse from randomisation (Visit 2) and for 1 month after the last dose of inhaled IFN-β1a/matching placebo to prevent pregnancy
  • Women not of childbearing potential are defined as women who are either permanently sterilised (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal. Women will be considered post-menopausal if they have been amenorrhoeic for 12 months prior to the planned date of randomisation without an alternative medical cause. The following age specific requirements apply: women <50 years old will be considered post-menopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatment and if follicle stimulating hormone (FSH) levels are in the postmenopausal range; women ≥50 years old will be considered post-menopausal if they have been amenorrhoeic for 12 months or more following cessation of all exogenous hormonal treatment. If, in the setting of the pandemic, the use of an acceptable birth control method is not possible, the decision to enrol a woman of childbearing potential should be based on the benefit-risk for the patient, which should be discussed with the patient at the time of the informed consent.

Exclusion Criteria:

  • Evidence of ongoing SARS-CoV-2 infection for more than 3 weeks, confirmed by a validated molecular assay or validated antigen assay
  • Non-invasive ventilation continuous positive airway pressure/bilevel positive airway pressure (CPAP/BiPAP) or high-flow nasal oxygen therapy (WHO OSCI score of 5)
  • Endotracheal intubation and invasive mechanical ventilation (WHO OSCI score of ≥6) or admission to intensive care
  • Previous SARS-CoV-2 infection confirmed by a validated molecular assay or validated antigen assay
  • Any condition, including findings in the patients' medical history or in the pre-randomisation 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
  • Participation in previous clinical trials of SNG001
  • Current or previous participation in another clinical trial where the patient has received a dose of an Investigational Medicinal Product containing small molecules within 30 days or 5 half-lives (whichever is longer) prior to entry into this study or containing biologicals within 3 months prior to entry into this study
  • Inability to use a nebuliser with a mouthpiece
  • Inability to comply with the requirements for storage conditions of study medication in the home setting
  • History of hypersensitivity to natural or recombinant IFN-β or to any of the excipients in the drug preparation
  • Females who are breast-feeding, lactating, pregnant or intending to become pregnant.
