Clinical Trial Summary

The REspiratory Syncytial virus Consortium in EUrope (RESCEU) is an Innovative Medicine Initiative (IMI) effort funded by the EU under the H2020 framework to define and understand the burden of disease caused by human respiratory syncytial virus (RSV) infection. RSV causes severe disease in individuals at the extremes of the age spectrum and in high risk groups. It was estimated that RSV was associated with 34 million cases of acute respiratory tract infection (ARTI), 3.4 million ARTI hospitalizations and 55,000 to 199,000 deaths in children <5 years in 2005 worldwide. These estimates were based on limited data and there is a substantial gap in knowledge on morbidity and associated healthcare and social costs in Europe. New vaccines and therapeutics against RSV are in development and will soon be available on the European market. RESCEU will deliver knowledge of the incidence and burden of disease RSV in young children and older adults in Europe, which is essential for stakeholders (governments, etc) to take decisions about prophylaxis and treatment.

Objective:

To determine the burden of disease due to RSV in young children.

Study design:

Prospective epidemiological, observational, multi-country, multicenter cohort study.

Study population:

Birth cohort of healthy infants (follow-up from birth until the age of 3 years maximum):

• Passive birth cohort (n=9,000).

• Active birth cohort (n=1,000).

Main study parameters/endpoints:

The primary endpoint of the study is the incidence of RSV infection-associated ARTI, RSV associated medically attended (MA) ARTI (active birth cohort) and RSV related hospitalization (passive birth cohort) in infants (< 1 year) during 3 RSV seasons. In addition, a major secondary endpoint is RSV attributable burden of wheezing.

Description:

This will be a multi-country, multicenter, prospective, observational cohort study conducted across 3 consecutive years to determine the incidence of RSV infection, RSV associated MA-ARTI and RSV related hospitalization in a birth cohort of healthy subjects, recruited from the general population.

At birth parents will be asked by a member of the study team to participate in the active cohort. If enrolled, a nasopharyngeal sample, a blood sample, a buccal sample, and urine and stool samples will be collected from the baby in the first week after birth. The blood sample will be collected by means of a heel prick or a venepuncture, if possible, in combination with an already scheduled moment of blood sampling. Respiratory tract symptoms will be assessed weekly during the RSV season by telephone or email or (daily) telephone app. If a child experiences a new episode of ARTI according to the parents, the study team will visit the child to collect a nasopharyngeal sample, 200µl is used to perform a point of care (POC) test for RSV, and the rest will be stored for additional viral testing by Reverse Transcription-Polymerase Chain Reaction (RT-PCR). If RSV is positive, parents will be asked informed consent to obtain additional blood, nasopharyngeal, urine and stool samples at the time of RSV infection and 6-8 weeks after RSV infection.

Parents of all children in the active cohort will be asked yearly to fill in a questionnaire until age 3 years maximum or till end of study (defined as the moment that the last included subject has been followed up for 12 months).

If parents decline to participate in the active birth cohort, informed consent will be asked for passive follow up. Parents of participants in passive follow-up will be asked to fill in a questionnaire at birth and after one year. If their child was admitted to the hospital because of an ARTI, clinical data will be collected retrospectively from the hospital. Participating hospitals will perform RSV tests as part of standard diagnostic care in children <1 year of age who are admitted with ARTI. Only children with hospitalization due to ARTI will be followed up by a yearly questionnaire until age 3 years maximum or till end of study (defined as the moment that the last included subject has been followed up for 12 months).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of participants with a Medically attended RSV acute lower respiratory tract infection (MA-RSV-ALRI) based on a positive RT-PCR for RSV who visit a clinician during the RSV-ALRI.	Lower respiratory tract infection proven to be caused by RSV for which medical consultation (general practitioner/specialist/hospitalization) is required. RSV infection is confirmed using RT-PCR from a nasal swab collected by the study team in the active cohort in case of respiratory infection. In the passive cohort, this information is collected from medical data from the hospital in case of hospitalization.	In the active cohort during the RSV season (Oct-May), for all participants after 1 year (questionnaire)
Primary	Number of participants with a RSV hospitalization (hospitalization with RT-PCR confirmed RSV).	Hospitalization for a respiratory tract infection proven to be caused by RSV. This information is collected from the hospital data. RSV must be confirmed by RT-PCR.	In the active cohort during the RSV season (Oct-May), for all participants after 1 year (questionnaire)
Primary	Number of participants with an RSV infection	Incidence of RSV outside of the medical setting (active cohort only). When participants experience respiratory symptoms, the study team plans a visit to perform RSV diagnostics (nasopharyngeal swab).	Active cohort only, during the RSV season (Oct-May)
Secondary	RSV-related wheeze incidence	To estimate the incidence and frequency of RSV-related wheeze up to age 3 years. Wheeze will be assessed in questionnaires during the winter season follow-up (active cohort) and after the one, two and three years of follow-up (active and passive cohort).

Secondary	Effect of RSV on Health-Related Quality of Life (HRQoL)	Effect of an RSV infection on the quality of life of the child and it's parents. In various questionnaires the standardized EuroQol questionnaire is used to assess the quality of life. The questionnaire contains questions on mobility, self-care, usual activities, pain/discomfort, anxiety and worries about the child, as well as a scale to assess their current health and the health of their child from 0-100 (0 being the worst health imaginable, and 100 the best health possible).	Quality of Life is assessed at baseline, during the RSV season and after 1,2,3 years of life.
