A Phase 2a, Randomized, Double-blind, Placebo-controlled Trial to Evaluate the Antiviral Activity, Safety, and Pharmacokinetics of Repeated Oral Doses of JNJ-64281802 Against Dengue Serotype 3 Infection in a Dengue Human Challenge Model in Healthy Adult Participants

Accepts healthy volunteers


This research will study an investigational drug called JNJ-64281802 (JNJ study drug) so we can find out if it works to prevent infection with DENV. We are also studying its safety and how it acts in people’s bodies.

To do this, we will give you the JNJ study drug (or a placebo) for 5 days before giving you a shot of a dengue virus called rDEN3Δ30 (referred to as DENV-3). You will continue to take the JNJ study drug until Study Day 21 (or for 26 days total). You will be asked to return to the clinic every day including weekends from Day -3 through Day 20 to receive JNJ study drug. These visits will last about 60 – 90 minutes.

We want to find out if the JNJ study drug will keep you from having symptoms of dengue virus. We hope to find a medication we can safely give to people in the future to prevent dengue virus infection.
