Treatment Study of Metronidazole to Treat Dientamoebiasis in Children (DFPT)

June 25, 2013 updated by: Dennis Roser, Statens Serum Institut

Metronidazole for the Treatment of Dientamoebiasis in Children in Denmark - A Randomized, Placebo-controlled, Double-blinded Clinical Trial

Introduction: Dientamoeba fragilis (DF) is a commonly occurring intestinal protozoan that is considered a possible cause of infectious gastrointestinal disease in adults and children. DF has a particular high prevalence in children, and it is suspected that children present more symptoms in infection than adults. However, evidence of causality is lacking, treatment regimens are largely untested in controlled trials, and the most commonly used antibiotic against DF in Denmark, metronidazole, has never been tested against placebo.

Main objective: To determine the clinical effect of metronidazole in DF-infected children with gastrointestinal complaints, where no other aetiology is known and no other gastrointestinal pathogens could be shown.

Study Overview

Status

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.

Study Type

Enrollment (Anticipated)

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.

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

3 years to 12 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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
Overall gastrointestinal symptoms, day 14
Time Frame: 14 days after end of treatment period

All participants receive 10 days of treatment with study drug (placebo or active). Primary outcome measure is registered on day 14 after end of treatment, using a questionnaire for the parents of the study participant.

Measuring will be done using a VAS-score scale, addressing overall level of gastrointestinal symptoms in the previous 14 days. Results will be noted as a value from 0 to 10.
14 days after end of treatment period

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
Realtime PCR for D. fragilis, day 14
Time Frame: Sample collection 14 days after end of treatment period

Secondary outcome measure will be registered using a specific realtime PCR for D. fragilis, performed on faecal samples collected from study-participant.

Results will be noted as either positive or negative.
Sample collection 14 days after end of treatment period
