Summary

This trial is testing a new drug, JNJ-64281802, to see if it can prevent or treat dengue fever in healthy adults exposed to Dengue Serotype 3. The drug aims to stop the virus from multiplying.

Who is the study for?
Healthy adults aged 18-55 with normal clinical tests, ECGs, and blood pressure can join this trial. They must not be pregnant or planning pregnancy, agree to use contraception, avoid donating blood or sperm for a certain period, and refrain from drug abuse. Exclusion includes HIV/HBV/HCV infection, recent travel to dengue regions, immunodeficiency conditions, significant alcohol/drug abuse history.
What is being tested?
The study is testing JNJ-64281802's effectiveness in preventing/treating dengue fever compared to a placebo. Participants will receive different dosing regimens of the drug (weekly Y1/Z2 or daily X) including high and medium/low doses versus placebo after being exposed to Dengue Serotype 3 virus.
What are the potential side effects?
Potential side effects are not detailed but may include typical reactions related to oral medications such as digestive issues or allergic responses specific to the components of JNJ-64281802.

Treatment Details

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
Assess the antiviral activity of the study drug (JNJ 64281802) versus placebo in terms of reduction of dengue infection.
Secondary study objectives
Assess how the body handles the study drug (JNJ-64281802) following repeated oral dosing. Using Pharmacokinetic analysis from repeated blood samples taken at specified time points after drug administration during 2 inpatient stays.
Assess the dengue infection-associated Adverse Events (unwanted medical occurrence).
Recording of vital signs to assess the safety and tolerability of the study drug (JNJ 64281802).

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: JNJ-64281802Experimental Treatment6 Interventions
There are two cohorts and three groups in each cohort. Cohort 1 consists of Group 1a, Group 1b and Group 2. Cohort 2 consists of Group 3, Group 4, and Group 5. Within each group, participants will either be randomized to receive study drug or placebo. Four participants will be enrolled in Group 1a before enrolling the remaining participants to Group 1b (12 participants) and Group 2 (14 participants) in Cohort 1. Based on the interim analysis results of Cohort 1, three groups for Cohort 2 were created. Eight participants will be enrolled in each of the three groups (Group 3, Group 4, and Group 5).
Group II: PlaceboPlacebo Group1 Intervention
There are two cohorts and three groups in each cohort. Cohort 1 consists of Group 1a, Group 1b and Group 2. Cohort 2 consists of Group 3, Group 4, and Group 5. Within each group, participants will either be randomized to receive study drug or placebo. Four participants will be enrolled in Group 1a before enrolling the remaining participants to Group 1b (12 participants) and Group 2 (14 participants) in Cohort 1. Based on the interim analysis results of Cohort 1, three groups for Cohort 2 were created. Eight participants will be enrolled in each of the three groups (Group 3, Group 4, and Group 5).

Other Research
The most common treatments for Dengue Fever focus on supportive care, including hydration and pain relief, as there are no specific antiviral drugs widely approved for Dengue. However, investigational drugs like JNJ-64281802 are being studied for their antiviral activity against Dengue Virus. These antiviral agents work by inhibiting viral replication, which can reduce the viral load in the body and potentially lessen the severity and duration of the illness. This is crucial for Dengue Fever patients as it can help prevent complications such as severe dengue, which can lead to hemorrhage, organ failure, and death. Effective antiviral treatments could significantly improve patient outcomes and reduce the burden on healthcare systems.
