Is this trial a fit for you?

Likely a good fit

Ideal candidates are males and females aged 18 to 60 who have a confirmed dengue infection and have experienced fever within the last 48 hours.

Probably not a fit

Patients with severe dengue symptoms or significant medical conditions that require other medications may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the efficacy and safety of EYU688 in treating patients with dengue fever compared to a placebo. It is a randomized, participant- and investigator-blinded, placebo-controlled trial that aims to measure the impact of EYU688 on dengue viral load, fever clearance time, and clinical symptoms. The study includes two cohorts with different pharmacokinetic sampling schedules to gather comprehensive data on the drug's effects.

Why it matters

Potential benefit: If successful, this treatment could significantly improve recovery times and clinical outcomes for patients suffering from dengue fever.

How similar studies have gone: While there have been studies on dengue treatments, the specific approach with EYU688 is novel and has not been extensively tested in this context.

* Usage of any anticoagulant drugs.
* Current significant medical conditions or illness that the investigator considers should exclude the participants, especially those that require continuation of other medications likely to have an interaction with the study drug.
* Pregnant or nursing (lactating) women.
* Clinical signs and symptoms for severe dengue according to Dengue Guideline (WHO 2009) at screening.

  * ALT, AST levels more than 3 X upper limit of normal (ULN)
  * Total bilirubin \>24 μmol/L
* Usage of PPIs (proton pump inhibitor) which could affect absorption of EYU688 due to stomach pH value increase up to 48 hours prior to screening.
* Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 4 days after stopping of investigational drug.
* History or long-QT syndrome, or clinically significant ECG abnormalities, or any of the following ECG abnormalities at screening:
