This is a two-arm, randomized, open label, two-center, controlled study to evaluate the safety and efficacy of Viusid plus Asbrip in patients with mild and moderate symptoms of respiratory illness caused by Coronavirus 2019 infection.

This is a two-arm, randomized, open label, two-center, controlled study to evaluate the safety and efficacy of Viusid plus Asbrip in patients with mild and moderate symptoms of respiratory illness caused by Coronavirus 2019 infection.

A total of 60 subjects will be randomized 2:1 in this study. 40 patients will be assigned to receive daily oral doses of 30 ml of Viusid and 10 ml of Asbrip every 8 hours and standard care. Other 20 patients will be assigned to receive only standard care.

Treatment duration: 21 days

Inclusion Criteria:

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

2. Subjects with mild-to-moderate symptoms of respiratory illness caused by coronavirus 2019 infection as defined below:

   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.
