Serologic Response to Porcine Circovirus Type 1 (PCV-1) in Infants Following Administration of Rotarix™

April 2, 2015 updated by: GlaxoSmithKline

Blinded Retrospective Laboratory Evaluations to Assess the Serologic Response to Porcine Circovirus Type 1 (PCV-1) in Infants Following the Administration of GlaxoSmithKline (GSK) Biologicals' Human Rotavirus Vaccine (444563)

This study aims to evaluate the serologic response to PCV-1 in the serum samples previously collected during initiation of vaccination series of Human Rotavirus (HRV) vaccine studies (1-2 months post Dose 2 of HRV vaccine or placebo). Additionally, pre-vaccination sera samples from any infants testing positive for PCV-1 antibodies at the post-vaccination time point will also be evaluated.

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

Serum samples collected from 6 clinical trials previously conducted for HRV vaccine (Rotarix™) are used in this study.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Actual)

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

1 month to 2 months (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Infants aged 6 to 12 weeks from 6 previously completed clinical trials, who received 2 doses of either Rotarix™ or Placebo.

Description

Inclusion Criteria:

Not applicable as no subjects will be actively enrolled in this study, only the sera samples of the subjects who were a part of previously conducted trials will be used for testing. However, the archived serum samples of only those subjects who satisfy the following criteria will be included in this study:

  • Subjects who received two doses of HRV vaccine or Placebo and were included in the ATP cohort for immunogenicity in the primary studies listed.
  • Subjects for whom their parents or Legally Acceptable Representatives (LARs) had agreed that their child or wards blood samples could be used for further research while giving consent for any of the primary studies listed.
  • Subjects who have sufficient residual volume of serum samples at both pre- and post-vaccination time points.

Exclusion Criteria:

  • Not Applicable

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
HRV Group
Subjects who had received 2 doses of HRV vaccine in previous studies.
Procedure: Serum sample
Serum samples collected at pre-vaccination and at 1-2 months post Dose 2 in the previously conducted clinical trials will be assessed for anti-PCV-1 antibodies in this study. Additionally, pre-vaccination sera samples from any infants testing positive for PCV-1 antibodies at the post-vaccination time point will also be evaluated.
Placebo Group
Subjects who had received 2 doses of placebo in previous studies.
Procedure: Serum sample
Serum samples collected at pre-vaccination and at 1-2 months post Dose 2 in the previously conducted clinical trials will be assessed for anti-PCV-1 antibodies in this study. Additionally, pre-vaccination sera samples from any infants testing positive for PCV-1 antibodies at the post-vaccination time point will also be evaluated.

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.
Outcome Measure
Time Frame
Seropositivity rates for anti-PCV-1 antibodies.
Time Frame: At 1-2 months post dose 2 of HRV vaccine or placebo.
At 1-2 months post dose 2 of HRV vaccine or placebo.
Seroconversion rates for anti-PCV-1 antibodies.
Time Frame: At 1-2 months post dose 2 of HRV vaccine or placebo.
At 1-2 months post dose 2 of HRV vaccine or placebo.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
February 1, 2014

Primary Completion (Actual)

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
