About this study

Official title: Safety Study of GSK Biologicals' Rotarix® (Rotavirus Vaccine, Live, Oral) Administered to a Birth Cohort in United States Health Insurance Plans

This observational cohort study, conducted through two existing large administrative health databases in the US (outside the Vaccine Safety Datalink) is planned to confirm the safety profile regarding lack of any association of intussusception with Rotarix within 60 days of vaccination in a real life setting (routine use) in the US. This study will also include monitoring of Kawasaki disease, convulsions, hospitalizations due to acute lower respiratory tract infections and all-cause deaths within 60-days of vaccination.

This study involves three cohorts, one exposed and two control cohorts: infants who receive Rotarix (Exposed cohort) and infants who receive IPV vaccination (Unexposed cohort A and B).

This is a combined prospective and retrospective cohort study. Prospective component of the study identifies and compares study outcomes following Rotarix and IPV vaccination in the Exposed cohort and Unexposed cohort A, respectively.

Retrospective component of the study identifies and compares study outcomes following IPV vaccination in the Unexposed cohort B.

Study groupRoleWhat they receive
HRV cohortHRV (Human Rotavirus) cohort consisted of infants aged less than 1 year, enrolled in the participating health insurance plans within 30 days of birth and who received at least one dose of Rotarix vaccination as part of their normal health care (with no previous dose of RotaTeq prior to or concurrent with the first Rotarix vaccination).
Receives: Other: Health Insurance Database
Concurrent Control cohortConcurrent control cohort consisted of infants aged less than 1 year, enrolled in the participating health insurance plans, who were contemporaneous with the Rotarix vaccinees and who received at least one dose of IPV (Inactivated Poliovirus vaccine) with or without RotaTeq vaccination (with no previous dose of Rotarix prior to or concurrent with the first IPV vaccination).

Recent Historical Control cohortRecent historical control cohort consisted of infants aged less than 1 year of age, enrolled in participating health insurance plans, vaccinated with at least one dose of IPV (Inactivated Poliovirus vaccine) between 1 January 2004 (OptumInsight) or 1 January 2006 (HealthCore) and 31 July 2008 and who did not receive any dose of rotavirus vaccination during the study period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence Rates of Intussusceptions (IS) Among the HRV Cohort and Comparator Cohorts

    Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).

    Measured: 60 days following each vaccination

  2. Incidence Rates of IS Among the HRV Cohort and Comparator Cohorts

    Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).

    Measured: 7 days following each vaccination

  3. Incidence Rates of IS Among the HRV Cohort and Comparator Cohorts

    Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).

    Measured: 30 days following each vaccination

Secondary outcomes (6)
  1. Incidence Rates of Kawasaki Disease Among the HRV Cohort and Comparator Cohorts

    Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).

    Measured: 60 days following each vaccination

  2. Incidence Rates of Convulsions Among the HRV Cohort and Comparator Cohorts

    Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).

    Measured: 60 days following each vaccination

  3. Incidence Rates of Acute Lower Respiratory Tract Infection (LRTI) Hospitalisation Among the HRV Cohort and Comparator Cohorts

    Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).

    Measured: 60 days following each vaccination

  4. Incidence Rates of Acute LTRI Hospitalisation Among the HRV Cohort and Comparator Cohorts

    Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).

    Measured: 7 days following each vaccination

  5. Incidence Rates of Acute LTRI Hospitalisation Among the HRV Cohort and Comparator Cohorts

    Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).

    Measured: 30 days following each vaccination

  6. Incidence Rates of All-cause Mortality Among the HRV Cohort and Comparator Cohorts

    Incidence rates were calculated following the first 2 doses of study vaccine as the number of events divided by the sum of the person-time in that risk period. Person-time was defined as the number of days at risk for the study outcomes. Person-time was calculated in months by dividing the number of person-days by (365.25/12).

    Measured: 60 days following each vaccination

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

Yes. Results are posted in the registry (first posted 25 Jan 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Incidence Rates of Intussusceptions (IS) Among the HRV Cohort and Comparator Cohorts (time frame: 60 days following each vaccination). The study lists 3 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 25 Jan 2019.
