Epidemiological, Observational and Post Marketing Study of Rotarix™ in Children With Severe Gastroenteritis in Belgium

January 16, 2017 updated by: GlaxoSmithKline

Epidemiological, Observational, Post Marketing Study of the Genetic Stability of GSK Biologicals' Rotavirus Vaccine (Rotarix™) in Children <5 Years of Age Diagnosed With Severe Gastroenteritis, in Belgium

The main aim of this study is to investigate cases of rotavirus gastroenteritis in Belgian children with opportunity to receive Rotarix™ to monitor the potential occurrence of genetic drifts (point mutations) in the vaccine strain and the occurrence of genetic shifts (re-assortments) between vaccine and naturally circulating wild-type strains in Belgium population after the introduction of Rotarix™. The study will also detect if there is any alteration in rotavirus pathogenicity conferred by re-assortment and if the mutated vaccine strain is still efficacious in preventing rotavirus gastroenteritis.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

This study is conducted in two phases: Phase I and Phase II. Phase I will be retrospective and consist of re-using the data collected in RotaBel (EPI-ROTA-111426) study. Phase II will be prospective and consist of maintaining the active surveillance system to identify rotavirus cases in several hospitals in Belgium.

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.

Ages Eligible for Study

3 months to 5 years (CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Children confirmed with G1 and/or P[8] cases from the RotaBel study, children between 14 weeks and <5 years of age, hospitalized for severe gastroenteritis in the study hospitals and who are tested positive for rotavirus

Description

Inclusion Criteria:

Phase I:

• Vaccinated and unvaccinated confirmed G1 and/or P[8] rotavirus gastroenteritis cases from the RotaBel study.

Phase II:
