Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Male or female adults aged ≥18 years at the time of enrollment.

    Mild (uncomplicated) Illness:

    • Diagnosed with COVID-19 by a standardized RT-PCR assay and
    • Mild symptoms, such as fever, rhinorrhea, mild cough, sore throat, malaise, headache, muscle pain, or malaise, but with no shortness of breath and
    • No signs of a more serious lower airway disease and
    • RR<20, HR <90, oxygen saturation (pulse oximetry) > 93% on room air

    Moderate Illness:

    • Diagnosed with COVID-19 by a standardized RT-PCR assay and
    • In addition to symptoms above, more significant lower respiratory symptoms, including shortness of breath (at rest or with exertion) or
    • Signs of moderate pneumonia, including RR ≥ 20 but <30, HR ≥ 90 but less than 125, oxygen saturation (pulse oximetry) > 93% on room air and
    • If available, lung infiltrates based on X-ray or CT scan < 50% present
  3. Clinically normal resting 12-lead ECG at screening visit or, if abnormal, considered not clinically significant by the Principal Investigator.
  4. Subject (or legally authorized representative) provides written informed consent prior to initiation of any study procedures.
  5. Understands and agrees to comply with planned study procedures.

Exclusion Criteria:

  1. Subjects showing signs of acute respiratory distress syndrome (ARDS) or respiratory failure necessitating mechanical ventilation at the time of screening.
  2. History of severe chronic respiratory disease and requirement for long-term oxygen therapy.
  3. Subjects showing signs of clinical jaundice at the time of screening.
  4. History of moderate and severe liver disease (Child-Pugh score >12).
  5. Subjects requiring Renal Replacement Therapy (RRT) at the time of screening.
  6. History of uncontrolled diabetes.
  7. History of severe chronic kidney disease or requiring dialysis.
  8. Any uncontrolled active systemic infection requiring admission to an intensive care unit (ICU); Note: Subjects infected with chronic hepatitis B virus or hepatitis C virus will be eligible for the study if they have no signs of hepatic decompensation.
  9. Patients with malignant tumor, or other serious systemic diseases.
  10. Patients who are participating in other clinical trials.
  11. Patients who have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to Viusid or Asbrip are not eligible.

Note: Empirical antibiotic treatment for secondary bacterial infections is allowed during the study.

Outcomes

Primary Outcome Measures

Clinical Improvement
Clinical Improvement as assessed by change in total symptom score ranging from 0-12. The symptom score includes: [everyday assessment, up to 21 days]. Fever (temperature in oC) based on a scale 0-3: 0 <36,7; 1 =36,7-37,8; 2 =37,8-38,9; 3 > 38,9. Cough on a scale 0-3: 0 = no cough, 1 = mild, 2 = moderate, 3 = severe. Shortness of breath based on a scale 0-3: 0 = no shortness of breath, 1 = with moderate intensity exercise, 2 = with walking on flat surface, 3 = short of breath with getting dressed or daily activities. Fatigue on a 0-3 scale: 0 = no fatigue, 1 = mild fatigue, 2 = moderate fatigue, 3 = severe fatigue. Composite score is a sum of mentioned four symptom scores, assessed every day up to 21 days. It ranges from 0 to 12.
Time to semirecover
Efficacy will be determined by the number of days required to reach a 50 percent reduction in the composite score, i.e. "time to semirecovery" (primary outcome measure).
Symptom resolution
Symptom resolution of COVID-19 disease The number of days required to reach symptom score <0,25 for each one of four symptom category mentioned before.
Time to recovery
Time (days) to recovery from COVID-19 disease The number of days required to reach composite score <1.

Secondary Outcome Measures

Cumulative assessment of disease severity
Disease severity will be measured using a disease severity clinical event scale (assessed until day 21) Change from baseline in the patient's health status on an ordinal scale of 7 categories. Death Hospitalized, with invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO) Hospitalized, with non-invasive ventilation or high-flow oxygen devices Hospitalized, requiring supplemental oxygen Hospitalized, which does not require supplemental oxygen Not hospitalized, limitation of activities. Not hospitalized, without limitations in activities. Note: lower scores mean a worse result. Note: lower scores mean a worse outcome
