Respiratory Syncytial Virus study: Arexvy
Official title Immunogenicity of RSVPreF3 Vaccine in Immunocompromised Persons
ClinicalTrials.gov ID: NCT07050732
What this study is testing
What is Arexvy?
an investigational vaccine being studied for preventing respiratory syncytial virus (RSV) in people with weakened immune systems is designed to stimulate the immune system to recognize and fight RSV by presenting an RSV protein antigen
Also referred to as adjuvanted RSVPreF3.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to see how well the Arexvy vaccine works and how safe it is in people with weakened immune systems, comparing one and two dose schedules.
- Who it's for
- Adults who have a weakened immune system.
- What's involved
- Participants will receive three doses of the vaccine over a year, keep a symptom diary for a week after each dose, and undergo in‑person checkups and tests.
- Time commitment
- The trial lasts about 1.5 years with three clinic visits and six phone calls.
- Phase 2: a mid-size study of how well it works
