About this study

Official title: A Randomized Controlled Trial of Echinacea in Children

This is a randomized trial to determine if echinacea is effective in shortening the length and/or lessening the severity of colds in children 2 through 11 years old.

Read the detailed description

Upper respiratory tract infections (URI's) are a significant health burden in childhood. URI's are a major reason for visits to health care providers, and up to 35 percent of young children at any given time are taking some over-the-counter cold medication. Unfortunately, data suggest that most of these medications have limited effectiveness. Alternative medical therapies are growing in popularity; in a recent survey of parents of children being seen by pediatricians in Seattle, Washington, 24.2 percent indicated that their child had been seen by an alternative medicine health care provider, and 53.3 percent received therapies for the treatment of URI's in children. The proposed study is a randomized, double blind, placebo controlled trial of Echinacea for the treatment of URI's in children 2-11 years old. The aims of the project are: to determine if Echinacea shortens the duration and/or lessens the severity of URI's, if children receiving Echinacea for treatment of URI's have a reduced rate of secondary bacterial infections, and to determine if the use of Echinacea in patients 2-11 years old is associated with any significant side effects. A two-year study of 600 children is planned. Not only will the results of this study determine if Echinacea, the most popular medicinal herb sold in the United States, is an effective therapy for URI's in children, the study will provide a design framework for further assessment on the efficacy of other complementary and alternative medicines in children.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Echinacea in people with Common Cold, run by National Center for Complementary and Integrative Health (NCCIH) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Aug 2006. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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.

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 18 Aug 2006.
