Evaluation of the Effectiveness and Impact of Nirsevimab Administered as Routine Immunization (NIRSE-GAL)

December 21, 2023 updated by: Federico Martinón Torres
A longitudinal observational study based on routinely collected data on hospital and health care use for RSV infections will be undertaken. The Galician public health registries will be used for data collection including baseline information and follow-up data. Historical data will be retrieved for comparison purposes. The study aims to observe and analyze data from all the eligible children in Galicia for nirsevimab treatment. The number of eligible children is expected to be approximately 14,000 per each RSV season.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to evaluate the impact of nirsevimab in preventing RSV in healthy infants and high-risk children less than 24 months of age at the start of RSV season in Galicia.

The target population to receive nirsevimab is around 14,000 subjects including all healthy newborns during the RSV season, those < 6 months at the start of the season, as well as those < 24 months with comorbidities at the start of the season. Nirsevimab will be administered as part of the immunization program of Galicia and following the implementation plan designed by the Public Health authorities, using the vaccination facilities of the Galician system, i.e., hospitals and primary care centres. Appointments for administration and registration of administered doses will be performed as per usual immunization protocols. The expected coverage with nirsevimab in the target population is expected to be high (>80%).

RSV testing is routinely performed in the hospital and emergency department settings. The Galician Regional Surveillance Information System will retrieve all the existing information of the different electronic databases for new RSV cases detected in Galicia, including hospitalization, primary care, drug administration and immunization. RSV case ascertainment and classification will be per- formed by a specialized clinical team according to pre-established definitions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
