Study Details

Study Description

Brief Summary

The purpose of this study is to characterize the effect on dengue viral load, fever clearance time as well as on clinical signs and symptoms with the treatment of EYU688 compared with placebo in patients with dengue fever.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

This is a randomized, participant- and investigator- blinded, placebo-controlled study to investigate the efficacy and safety of EYU688 administered orally in patients with dengue fever.

Due to the different PK sampling schedules applied, the study consists of two cohorts run in parallel (intensive PK [cohort 1] and sparse PK sampling [cohort 2]).

Outcome Measures

Primary Outcome Measures

  1. Viremia reduction (viral load reduction (VLR) on log scale) at 48 hours post treatment start [From predose to 48 hours post treatment start]

    Efficacy assessment of EYU688. It will allow to quantify the viremia reduction at 48 hours post treatment start from baseline.

Secondary Outcome Measures

  1. Time from fever onset to start of the first 48 hours period during which the oral temperature remained below 37.5℃ [From fever onset to Day 15]

    Efficacy assessment of EYU688. It will allow to assess the time needed between fever onset and defervescence.

  2. Time from fever onset to the first of two consecutive negative viremia by PCR [From fever onset to Day 15]

    Efficacy assessment will allow to assess the viremia kinetic from treatment start to Day15

  3. Area under the log-transformed viremia curve (AUC) from the first dose to Day 15 [From fever onset to Day 15]

    Efficacy assessment will allow to assess the viremia kinetic from treatment start to Day 15

  4. Changes of viral load over time [From baseline to Day 15]

    Efficacy assessment will allow to assess the viremia kinetic from treatment start to Day15

  5. Incidence and severity of Adverse Events (AEs) [From inclusion to Day 15]

    Incidence and severity of AEs by treatment group, including changes in vital signs, electrocardiograms (ECGs) and laboratory results qualifying and reported as AEs.

  6. Incidence and severity of Serious Adverse Events (SAEs) [From inclusion to Day 35]

    Incidence and severity of SAEs by treatment group

  7. Change of white blood cell count over time from baseline [From baseline to Day 15]

    Assessment of safety and tolerability of EYU688

  8. Change of platelet count over time [From baseline to Day 15]

    Assessment of safety and tolerability of EYU688

  9. Change of hematocrit level and percentage increase from baseline over time [From baseline to Day 15]

    Assessment of safety and tolerability of EYU688

  10. Change of AST, ALT levels over time [From baseline to Day 15]

    Assessment of safety and tolerability of EYU688

  11. No warning signs by day 7 of fever onset [From inclusion to Day 15]

    Assessment of the dengue fever clinical evolution under EYU688

  12. Diagnosis of severe dengue fever [From inclusion to Day 15]

    Assessment of the dengue fever clinical evolution under EYU688

  13. Diagnosis of dengue hemorrhagic fever (DHF) [From inclusion to Day 15]

    Assessment of the dengue fever clinical evolution under EYU688

  14. Plasma leakage [From inclusion to Day 15]

    Assessment of the dengue fever clinical evolution under EYU688

  15. Requiring fluid infusion [From inclusion to Day 15]

    Assessment of the dengue fever clinical evolution under EYU688

  16. Time from fever onset to clinical recovery [From fever onset to Day 15]

    Assessment of the dengue fever clinical evolution under EYU688

  17. PK parameter (Cmax) [From Day 1 to Day 6]

    Pharmacokinetic assessment of EYU688 in dengue fever patients

  18. PK parameter (Tmax) [From Day 1 to Day 6]

    Pharmacokinetic assessment of EYU688 in dengue fever patients

  19. PK parameter (partial AUCs) [From Day 1 to Day 6]

    Pharmacokinetic assessment of EYU688 in dengue fever patients

  20. PK concentrations following multiple doses [From Day 1 to Day 6]

    Pharmacokinetic assessment of EYU688 in dengue fever patients
