Overview
Brief Summary
The purpose of this study is to determine whether Rifamycin SV MMX is a safe and effective treatment for Traveler's Diarrhea.
Detailed Description
This is a multicenter, randomized, double-blind, placebo-controlled efficacy and safety study conducted in patients traveling to developing regions with a known high incidence of TD. Eligibility will be based on a symptom complex that is highly indicative of enteric acute bacterial infection without indication of systemic infection. Approximately 262 patients will be enrolled in the study and randomized at a 3:1 ratio to receive Rifamycin SV MMX® 400 mg or placebo orally twice daily for 3 days (72 hours). Treatment will be initiated on the day of Screening (Visit 1, Day 1), within 72 hours of onset of diarrhea. Daily doses of study drug will be taken at breakfast time and dinner time with a glass of liquid. Safety and efficacy will be assessed. Blood samples for routine safety tests (chemistry and hematology) will be collected at Visit 1 and at Visit 3 and sent to a local laboratory for analysis and reporting to the Investigator for safety monitoring. Urine samples for routine urinalysis (dipstick only) will be collected at Visits 1 and 3, and the results will be used by the Investigator for safety monitoring. If a patient's diarrhea and/or signs or symptoms of enteric infection worsen in a 24 hour interval of time during the treatment period or if the enteric illness fails to improve after 24 hours or more of therapy, the patient may receive Rescue Therapy. Rescue Therapy will be prescribed by the Investigator using local standard empiric therapy and/or guided by pathogen identification.

Outcomes
Primary Outcomes
Time to Last Unformed Stool (TLUS)
Time Frame: 24 hours
The primary endpoint is TLUS defined as the interval in hours between the first dose of study drug and the last unformed stool passed just before the start of Clinical Cure. An unformed stool is defined as either a soft or watery stool. TLUS will be calculated for each patient in the following manner: Step 1: Identify when the patient achieves Clinical Cure. Step 2: Moving backwards from this time, identify the time of the last unformed stool. Step 3: The TLUS equals the time from the first dose of study drug to the time of the last unformed stool identified in Step 2.
Secondary Outcomes
- Clinical Cure(24 hours)
