Primary Outcome Measures:
  • The primary objective is to evaluate the effect of TCN-032 compared to placebo in the development of clinical signs and symptoms of influenza (including upper respiratory, lower respiratory, systemic and fever). [ Time Frame: 7 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The main secondary objective is to evaluate the effect of TCN-032 compared to placebo in total virus shedding (measured by area under the curve [AUC]) from the nasal mucosa, measured by viral culture. [ Time Frame: 7 days ] [ Designated as safety issue: No ]

  • The time to peak of influenza symptoms or pyrexia [ Time Frame: up to 10 days ] [ Designated as safety issue: No ]
  • The daily incidence of influenza symptoms or pyrexia. [ Time Frame: up to 10 days ] [ Designated as safety issue: No ]
  • The proportion of the components of the primary objective: upper respiratory symptoms, lower respiratory symptoms, systemic influenza symptoms, pyrexia. [ Time Frame: 7 days ] [ Designated as safety issue: No ]

  • The proportion of any grade influenza symptoms, or pyrexia [ Time Frame: 7 days ] [ Designated as safety issue: No ]
  • The duration of any grade influenza symptoms, or pyrexia [ Time Frame: 7 days ] [ Designated as safety issue: No ]
  • The time to peak of any grade influenza symptoms, or pyrexia [ Time Frame: 7 days ] [ Designated as safety issue: No ]
