简要总结

The goal of this clinical trial is to learn if troxerutin works to prevent thrombotic events in mild or severe COVID-19 patients. It will also learn about the safety of troxerutin. The main questions it aims to answer are:

  • Does troxerutin lower the number of thrombotic events in participants?
  • What medical problems do participants have when taking troxerutin? Researchers will compare troxerutin to a placebo (a look-alike substance that contains no drug) to see if troxerutin works to prevent thrombotic events in COVID-19 patients.

Participants will:

  • Take troxerutin or a placebo every day for 7 days.
  • Visit the clinic at the first, fourth, seventh and 28th days after enrollment for checkups and tests
  • Keep a diary of their symptoms and the number of times of thrombotic events, bleeding events and type II HIT-related thrombocytopenia

入选标准

  • As long as the patient meets all of the following conditions, adult patients aged 18 and above are eligible for admission:
  • ► COVID-19 patients, defined as: positive RT-PCR (upper respiratory tract or lower respiratory tract) for SARS-CoV-
  • Mild COVID-19 patients are defined as:
  • Symptomatic patients meeting the case definition for COVID-19 without evidence of hypoxia or pneumonia. Common symptoms include fever, cough, fatigue, anorexia, dyspnea, and myalgia. Other nonspecific symptoms include sore throat, nasal congestion, headache, diarrhea, nausea/vomiting, and loss of smell/taste.
  • Severe COVID-19 patients are defined as:
  • Adolescents or adults with clinical signs of pneumonia (i.e., fever, cough, dyspnea, tachypnea) plus one of the following:
  • Respiratory rate ≥30 breaths/min
  • Severe respiratory distress
  • Oxygen saturation (SpO₂) ≤90% in room air
  • Progressive deterioration of clinical symptoms with lung imaging showing significant progression of lesions (>50%) within 24 to 48 hours.
  • Written informed consent provided according to Chinese law (by the patient, legal guardian, or deferred consent in emergencies).

排除标准

  • Patients with any of the following conditions will be excluded from the study:
  • Pregnant or lactating women.
  • Postpartum (within 6 weeks).
  • Extreme weight (100 kilograms).
  • Clinical need for heparin therapy.
  • Bleeding related to coagulation disorders, acute clinically significant bleeding, active gastrointestinal ulcers, or any organic lesions with high bleeding risk.
  • Platelet count <50 x 10^9/L.
  • Surgery within the last 15 days, or within 24 hours after spinal or epidural anesthesia.
  • History of intracranial hemorrhage, large ischemic stroke, known intracranial malformation or tumor, acute infective endocarditis.
  • Severe renal impairment (creatinine clearance <30 mL/min).
  • Iodine allergy.
  • Long-term use of oxygen supplementation.
  • Moribund patients or those expected to die during the current hospitalization due to underlying disease.
  • Patients deprived of freedom and those undergoing institutional psychiatric care.
  • Ward of the state or under guardianship.
  • Participation in other anticoagulant intervention studies.

结局指标

主要结局

Overall number of patients in prothrombotic state through 7 days

时间窗: Through 7 days

Assess coagulation-related parameters in patients' blood, including platelet count, prothrombin time (PT), antithrombin III activity (ATIIIa), plasma fibrinogen concentration (Fbg), and quantitative D-dimer.Patients with one or more indicators in the abnormal range, including PT \< 11s (reference interval: 11-14 s), FG \> 4g/L (reference interval: 2-4 g/L), D-dimer \< 0.5 μg/mL (reference interval: 0-0.5 μg/mL), are considered in a prothrombotic state.

次要结局

  • Tolerability of anticoagulation therapy(Through 28 days)
  • Adverse event(Through 28 days)
