Influenza Prevention Clinical Trials
Preventing the flu before it starts is an important goal of infectious disease research. 3A Research conducted an Influenza Prevention Clinical Trial evaluating an investigational long-acting antiviral for people at higher risk of flu complications. This study is no longer recruiting.

Influenza Prevention Clinical Trials
Understanding the Condition
Influenza is a contagious respiratory illness caused by influenza viruses. For some people — including those with certain underlying health conditions — the flu can lead to serious complications.
Most flu prevention focuses on seasonal vaccination, but researchers are also studying other approaches, such as long-acting antivirals, that may help protect people at higher risk.
By taking part in an Influenza Prevention Research Study in Texas, participants helped researchers understand investigational options for reducing the risk of influenza.
Important Information About Participation
Participation in Influenza Prevention Clinical Trials is voluntary. Investigational treatments are studied for safety and effectiveness, but there is no guarantee of personal benefit. Studies are conducted under strict regulatory guidelines. Consult with your healthcare provider before enrolling in any clinical research study.

About the Influenza Prevention Study
This Phase 3 study is evaluating an investigational long-acting antiviral conjugate for the prevention of influenza in adolescents and adults who are at higher risk of developing influenza complications. It is not yet known whether the investigational treatment is safe or effective for this use.
Part 1 of the study has closed. This study is no longer recruiting, and the information here is provided for reference.
What to Expect in Influenza Prevention Clinical Trials
Clinical trials give participants access to study-related care and monitoring under expert medical supervision. Participants underwent health evaluations and attended study visits. This study is no longer recruiting. You can view the studies we are currently recruiting for to find one that may be right for you.
Frequently Asked Questions
This study focused on people aged 12 and older who were considered at higher risk of complications from influenza.
No. This study is no longer recruiting. You can view the studies we are currently recruiting for to see if another study may be a fit.
Antivirals are medicines that act against viruses. A long-acting antiviral is designed to remain active in the body for an extended period. The treatment in this study is investigational and still being evaluated.
People at higher risk can include older adults and those with certain underlying health conditions. The study team will review whether you meet the study's specific criteria.
