About this study

Official title: A Multi-center, Multi-national, Prospective Surveillance Study of Respiratory Syncytial Virus Disease in Infants and Toddlers 6 to < 22 Months of Age

The study is a multi-center, multi-national, prospective surveillance study in which the study participants will not receive a study vaccine but will provide a baseline blood sample and be followed for acute respiratory disease during 6 months. The 6-month follow-up will occur for the most part during the Respiratory Syncytial Virus(RSV) season (based on enrollment timing and as per feasibility). A maximum of 1000 children from 6 to < 22 months of age are planned to be enrolled in 5 to 10 countries, 1 to 2 sites per country, targeting approximately 100 participants per country. The purpose of the study is to assess the seroprevalence and incidence of RSV disease during the study period in the targeted countries and sites for a Phase III vaccine study.

The duration of the study will be 6 months for each participant.

Questions about this trial

What is this clinical trial studying?

An observational study of Respiratory Syncytial Virus Infections, run by Sanofi Pasteur, a Sanofi Company at 15 sites in 7 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in Finland, United States, Ghana, Honduras, India and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

RSV A serum neutralizing antibody (Nab) titers (time frame: At Day 1). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2024; AzTrials last refreshed its copy on 8 Nov 2026.
