Treatment of Group A Beta Hemolytic Streptococcal Pharyngitis in Children in Low Resource Settings (TOPS)

July 2, 2010 updated by: Johns Hopkins University

Treatment of Pharyngitis Study (TOPS): A Randomized Equivalence Trial of Intramuscular Penicillin G vs. Oral Amoxicillin Antibiotics for the Treatment of Streptococcal Pharyngitis in Children in Developing Countries

The purpose of this study was to compare the microbiological effects of two different treatments: a single dose of intramuscular benzathine penicillin G (IM BPG) vs. a 10-day daily dose of amoxicillin for the treatment of GABHS pharyngitis in children in low resource settings. This study was a prospective multi-center randomized active control treatment trial. The trial is a non-inferiority equivalence trial, to determine if amoxicillin treatment is at least as effective as the currently given IM BPG treatment.

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.

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.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
558

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.

Ages Eligible for Study

2 years to 12 years (CHILD)

Accepts Healthy Volunteers

No

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
Eradication of Group A Streptococcus (GAS)
Time Frame: 21-28 days after 1st visit
The primary outcome of the study was bacteriologic treatment success, which was defined as eradication of GAS from the pharynx at the follow up visit. Eradication was defined as no GAS present on the throat culture.
21-28 days after 1st visit

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
Compliance to treatment
Time Frame: 21-28 days after 1st visit
Compliance with the amoxicillin treatment regimen was assessed at the follow up visit. The primary measure of compliance was the presence of antimicrobial activity in the urine-impregnated filter paper strips. For those who did not return the filter paper strip, compliance was measured by parent/guardian report during the exit interview. Patients who did not fulfill at least one of these criteria were considered noncompliant.
21-28 days after 1st visit
