Outcome Measures

Primary Outcomes (3)

  • Change of symptom score

    To evaluate the change of patient-reported symptom score in AK0529 arms compared with the change in placebo arm after treatment. The scale is Wang bronchiolitis score and the total score is reported with a range from 0 to 12. A decreasing value of total score represents clinical improvement. Subscales are not applicable in this symptom score.

    From Day 0 to Day 5

  • Incidence of adverse events during the study

    An adverse event (AE) is any untoward medical occurrence in a clinical investigation patient administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.

    From Day -3 to Day 14

  • Subject withdrawals due to treatment-emergent adverse events

    A treatment-emergent adverse event (TEAE) is an AE that first appears during treatment, which was absent before or which worsens relative to the pre-treatment state.

    From Day -3 to Day 14

Secondary Outcomes (1)

  • Area under curve change of viral load

    From Day 0 to Day 5

Interventions

AK0529DRUG

AK0529 is a novel compound being developed for the treatment of RSV infection. The capsule containing enteric coated AK0529 pellets will be orally administered to patients at one of a 100mg, 200mg or 300mg dose level.

Also known as: Ziresovir
