About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled Study Evaluating the Safety of Rifaximin for the Prevention of Travelers' Diarrhea in Subjects Traveling Outside the United States

The primary objective of this study is to assess the safety and tolerability of rifaximin 600 mg (3 x 200-mg tablets) once daily compared with placebo when taken for 14 days by healthy subjects to prevent travelers' diarrhea (TD) from all causes.

Read the detailed description

Travelers' diarrhea (TD) is the most common illness in travelers to the developing world, occurring in 60% or more of international travelers to high-risk areas. It can be quite debilitating for the usual 2 to 4 days of the illness and may lead to disruption of travel plans. Findings from recent studies have indicated that the chronic post-travel illness may prove to be of greater clinical and public health significance than the acute illness. Specifically, persistent diarrhea has been reported in 2% to 10% of travelers developing diarrhea. Moreover, bacterial enterocolitis, including that associated with TD, leads to post-infectious irritable bowel syndrome in 4% to 31% of patients.

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.

What does the primary outcome measure?

The primary endpoint in this study is the assessment of safety and tolerability of rifaximin 600 mg QD compared to placebo.. It is what the study was designed to measure, not a finding.

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?
