Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.
Outcome Measure
Measure Description
Time Frame
Intussusception Within 42 Days Following Any Dose of RotaTeq™/Placebo
Time Frame: Within 42 days following any dose of RotaTeq™/placebo
Number of participants with confirmed intussusception within 42 days after each vaccination with RotaTeq™/placebo.
Within 42 days following any dose of RotaTeq™/placebo
Occurrence of Rotavirus Disease Caused by Serotypes G1, G2, G3 and G4 That Occurs 14 Days Following the 3rd Vaccination
Time Frame: At least 14 days following the 3rd vaccination through the first full rotavirus season
Rotavirus gastroenteritis cases consist of all participants with one or more episodes classified as positive. Multiple positive episodes for one participant are counted as a single case.
At least 14 days following the 3rd vaccination through the first full rotavirus season

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
G1 Serum Neutralizing Antibody (SNA) Responses Against Rotavirus
Time Frame: 14 days following the 3rd vaccination
Number of participants with a 3-fold rise or greater in G1 Serum neutralizing antibody (SNA) responses against rotavirus from baseline to postdose 3.
14 days following the 3rd vaccination
Occurrence of Hospital Admissions and Visits to Emergency Departments (or the Equivalent at International Sites) for Rotavirus Disease Associated With Serotypes G1, G2, G3, or G4
Time Frame: At least 14 days following the 3rd vaccination
Health Outcomes Substudy - Occurrence of hospital admissions and emergency department visits for episode(s) of rotavirus gastroenteritis associated with serotypes G1, G2, G3, or G4 by treatment group. Occurrence was expressed as the annual number of events per 1000 person-years.
At least 14 days following the 3rd vaccination
Efficacy of a 3-dose Regimen of RotaTeq™ Against Moderate-to-severe Rotavirus Disease (Clinical Score >8) Caused by Serotypes G1, G2, G3, and G4 Occurring at Least 14 Days Following the Third Dose.
Time Frame: At least 14 days following the 3rd vaccination through the first rotavirus season
Number of participants with rotavirus gastroenteritis whose clinical score was >8 for the first episode and for the worst episode. Scores evaluated the intensity and duration of diarrhea, vomiting, fever, and behavioral symptoms. The total score for an episode is equal to the sum of the scores for each of the symptoms [range: total score 0 (best) to 24 (worst)].
At least 14 days following the 3rd vaccination through the first rotavirus season

Time Frame: At least 14 days following the 3rd vaccination through the first rotavirus season
Number of participants with rotavirus gastroenteritis whose clinical score was >16 for the first episode and for the worst episode. Scores evaluated the intensity and duration of diarrhea, vomiting, fever, and behavioral symptoms. The total score for an episode is equal to the sum of the scores for each of the symptoms [range: total score 0 (best) to 24 (worst)].
At least 14 days following the 3rd vaccination through the first rotavirus season

Geometric Mean Antibody Titer(s) (GMT) to Pertussis Toxin (PT), Pertussis Filamentous Haemagglutinin (FHA), and Pertussis Pertactin
Time Frame: 42 days following third dose
Measurement of immune response in the group that received RotaTeq™ and the group that received placebo was performed by determining geometric mean antibody titers to Pertussis Toxin (PT), Pertussis Filamentous Haemagglutinin (FHA), and Pertussis Pertactin. Antibody titers were measured with an indirect, non-competitive, enzyme immunoassay (EIA).
42 days following third dose
Geometric Mean Antibody Titer(s) (GMT) to Pneumococcal Serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F
Time Frame: 42 days following third dose
Measurement of immune response in the group that received RotaTeq™ and the group that received placebo was performed by determining geometric mean antibody titers to pneumococcal serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F. Serum antibody titers to type-specific pneumococcal polysaccharides were determined by an EIA.

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.
