You may not qualify if…

• (1) Known or suspected allergy to the components of Azvudine Tablets; (2) Patients diagnosed as severe or critical COVID-19 infection (Severe: 1. shortness of breath with RR ≥ 30 breaths/min; 2. oxygen saturation ≤ 93% when inhaling air at rest; 3. partial pressure of arterial oxygen (PaO2) / fraction of inspired oxygen (FiO2) ≤ 300 mmHg; 4. progressive worsening of clinical symptoms, and obvious lesion progression > 50% on lung images within 24 to 48 hours. Critical: 1. respiratory failure, requiring mechanical ventilation; 2. shock; 3. concomitant organ failure, requiring care in ICU); (3) Patients with severe liver disease (total bilirubin [TBIL] ≥ 2 × upper limit of normal (ULN), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≥ 3 × ULN; (4) Patients with severe renal insufficiency (glomerular filtration rate ≤ 60 mL/min/1.73 m2) or currently on continuous renal replacement therapy, hemodialysis, and/or peritoneal dialysis; (5) Patients with malabsorption syndrome or any other condition compromising gastrointestinal absorption, or patients requiring parenteral nutrition or with difficulty in taking the investigational product orally; (6) Known HIV infection; (7) Presence of diabetic ketosis or hyperosmolar hyperglycemic state (HHS); (8) Total neutrophil count < 750 cells/L; (9) Pregnant or lactating women or those who plan to have a child during participation in this study and within six months after the end of this study; (10) Currently participating in another clinical trial or currently using another investigational product; (11) Presence of other active infections (must be etiologically confirmed) in addition to COVID-19 infection; (12) Presence of any comorbidities requiring hospitalization and/or a surgical procedure within 7 days prior to the start of this study or a comorbidity considered life-threatening within 30 days prior to the start of this study; (13) Patients who have received or are expected to receive convalescent plasma for COVID-19; (14) Previous treatment with anti-viral agents that have been proved to be effective against COVID-19, including but not limited to Nirmatrelvir/Ritonavir or Molnupiravir (this criterion does not apply to use of glucocorticoids for reasons other than COVID-19); (15) Other conditions that make it inappropriate for the participant to take part in this trial at the investigator's discretion.
