Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Pharmacokinetic, Others, Safety

Part I: To assess the safety and tolerability of a single dose of EV25 intranasal administration in healthy participants. To determine the single-dose PK profile of EV25 intranasal administration in healthy participants.
Part II: To assess the safety and tolerability of a single dose of EV25 intranasal administration in healthy participants exposed to influenza H3N2. To assess the effect of single doses of EV25 on viral AUC compared to placebo in healthy participants exposed to influenza H3N2 with positive predose values.

Secondary objectives 3

  1. Part II: To determine the single-dose PK profile of EV25 intranasal administration in healthy participants exposed to influenza H3N2.
  2. Part II: To assess the effect of single doses of EV25 viral shedding compared to placebo in healthy participants exposed to influenza H3N2.
  3. Part II: To assess the effect of single doses of EV25 on measurements of disease severity compared to placebo in healthy participants exposed to influenza H3N2.
