Emetine for Dengue: seeing if a pill can help adults with dengue work better
Official title: Emetine for Viral Outbreaks: A Phase 2/3 Randomized, Double-Blinded, Placebo-Controlled Trial to Evaluate the Efficacy and Safety of Emetine for Dengue Fever (a.k.a. EVOLVE Antiviral Initiative)
Run by Johns Hopkins University · NCT07016321 · Data updated 2026-11-12
This study tests three groups—emetine 6 mg, emetine 12 mg, or a placebo—to see if a 7-day oral course can improve outcomes for adults with dengue.

Is this trial a fit for you?
✓Likely a good fit
Adults 18–65 with hospital admission for laboratory-confirmed dengue within the last 5 days (preferably 3 days) and at least two dengue-related symptoms.
✕Probably not a fit
Patients who are outside the 18–65 age range, have contraindications to emetine, or do not meet the lab/symptom criteria may not benefit.

What this trial studies
This interventional study evaluates the safety and effectiveness of oral emetine for adults aged 18–65 with laboratory-confirmed dengue. Participants are randomized to receive 6 mg or 12 mg of emetine daily for 7 days or a placebo, with daily monitoring for 28 days and blood sampling for about the first 5 days to track viral load and safety. The main questions are whether emetine affects 28‑day mortality or progression to severe dengue and what adverse events may occur. The trial includes hospitalized patients who meet dengue symptoms and lab criteria, with follow-up to assess clinical outcomes and safety signals. The Johns Hopkins University leads the study with Bharatpur Hospital as a collaborating site in Nepal.
Why it matters
Potential benefit: If successful, emetine could reduce the risk of severe dengue and shorten the course of illness for treated patients.
How similar studies have gone: Prior lab data suggested antiviral activity of emetine against dengue in cell studies, but clinical efficacy in humans remains to be proven.
