Detailed Description

This is an add-on study of efficacy and safety of intravenous injection of Xiyanping injection in pediatric subjects with severe Influenza-Like Symptoms. The purpose to determine the efficacy and safety of Oseltamivir Phosphate combined with or without Xiyanping injection in the treatment of severe Influenza-Like Symptoms. The study will enroll 72 Pediatric severe Influenza-Like Symptoms volunteers, who will be randomized into 2 groups (1:1 ratio): volunteers from the first group will receive Oseltamivir Phosphate and Xiyanping injection for severe Influenza; volunteers from the second group will receive Oseltamivir Phosphate for severe Influenza. Xiyanping injection will be administration as intravenous injection of 0.4mL/kg/day once daily for 7-10 days concomitantly with Oseltamivir Phosphate for severe Influenza-Like Symptoms.


  • Drug: Oseltamivir Phosphate
    • Take the dosage of Oseltamivir Phosphate recommended according to the instructions.support treatment such as antiasthmatic, expectorant and antipyretic use only in need.
  • Drug: Xiyanping injection+Oseltamivir Phosphate
    • Take the dosage of Oseltamivir Phosphate recommended according to the instructions.Xiyanping injection intravenous administration of 0.4mL/kg/day ,QD for 7-10 days.support treatment such as antiasthmatic, expectorant and antipyretic use only in need.

Arms, Groups and Cohorts

  • Experimental: Oseltamivir Phosphate+Xiyanping injection
    • Oseltamivir Phosphate+Xiyanping injection treatment for 7-10 days
  • Active Comparator: Oseltamivir Phosphate treatment only
    • Oseltamivir Phosphate treatment for 7-10 days

Clinical Trial Outcome Measures

Primary Measures

  • Time to Alleviation of Influenza Signs and Symptoms
    • Time Frame: Up to Day 12
    • Time to alleviation of influenza signs and symptoms is defined as the length of time taken from the start of treatment to the point at which all of the signs and symptoms are alleviation or recovery.
  • Duration of Fever
    • Time Frame: Up to Day 12
    • Length of time taken by participants to return to afebrile state

Secondary Measures

  • Signs and Symptoms Score from baseline
    • Time Frame: Up to Day 12
    • (1) recovery: symptom score reduction rate ≥ 95%; (2) markedly effective: symptom score reduction rate ≥ 70%; (3) progress: symptom score reduction rate ≥ 30%; (4) invalid: Symptom score reduction rate <30%.
  • Usage of antibiotic,hormone and incidence of critical cases
    • Time Frame: Up to Day 12
  • Time to Cessation of Viral Shedding by RT-PCR
    • Time Frame: Up to Day 12
  • Relief time of individual symptom such as:expectoration, cough
    • Time Frame: Up to Day 12
  • Disease efficacy criteria
    • Time Frame: Up to Day 12
    • (1) Healing: The body temperature is normal within 48 hours of treatment, the symptoms disappeared without repetition. (2) markedly effective: the body temperature is normal within 48 hours of treatment, and the symptom score is reduced by more than 2/3. (3) Effective: The body temperature is normal within 72 hours of treatment, and the remaining symptom scores are reduced by 2/3-1/3. (4) Invalid: The condition did not improve or worsened after 72 hours of treatment.
  • Imaging improvement rate: number of people with normal or baseline imaging
    • Time Frame: Up to Day 12
