Brief Summary

Apomivir® is extracted from a proprietary spirulina strain, FEM-101, a kind of blue cyanobacterium with patented freeze-thaw lysis and extraction method. According to the preclinical studies, Apomivir® have been proven to have excellent broad-spectrum anti-viral ability, especially for seasonal influenza viruses (Influenza virus A and B) that may cause illness, paralysis and even death, especially in children and elderly people. This phase II study is designed to evaluate the efficacy and safety of Apomivir® (120 mg b.i.d.) in subjects with seasonal influenza.

Outcome Measures

Primary Outcomes (2)

  • To evaluate the safety profile of Apomivir® treatment (120 mg b.i.d.).

    Safety endpoints: 1. Change in laboratory data 2. Adverse events 3. Serious adverse events (SAE)

    from day1 to day 29, the entire treatment period and follow-up period.

  • To evaluate the time to resolution of influenza symptoms defined as all flu symptom scores ≤ 1 after initiation of study treatment.

    The time to resolution of influenza symptom is defined as the duration from the study drug initiation to all flu symptom scores ≤ 1. Subject who is withdrawn prior to the resolution of influenza symptom is censored at the last known time point.

    from day 1 to day 29, depends on the time to sympton resolution of individual subjects.

Secondary Outcomes (6)

  • Change in virus titer.

    Day 3, 6 compared to baseline (Day 1)

  • Time to achieve afebrile

    after initiation of study treatment

  • Severity of influenza symptom score during study period

    twice daily from Day 1 to Day 6 and once daily until Day 29 or completely cured

  • Level of interference on daily activity and time to alleviation of the interference during study period

    twice daily from Day 1 to Day 6 and once daily until Day 29 or completely cured

  • Proportion of rescue medication used for fever or influenza symptoms during study period

    twice daily from Day 1 to Day 6 and once daily until Day 29 or completely cured

  • +1 more secondary outcomes
