Efficacy and Safety Evaluation of Levofloxacin Triple Therapy for Helicobacter Pylori Eradication

August 8, 2011 updated by: Deva Holding A.S.

A Monocentric, Open-label, Efficacy and Safety Evaluation Study of the Triple Therapy of 500 mg Levofloxacin, 1000 mg Amoxicillin and 30 mg Lansoprazole on Helicobacter Pylori Eradication in 60 Patients Infected With H. Pylori

Today, although the triple treatment with clarithromycin accepted as the primary treatment for Helicobacter pylori infection eradication is well tolerated, the eradication has been decreased to 65 %. However, the eradication resulting from TRIOL treatment with levofloxacin is expected to be 75 % or higher. If the target results can be reached, it will be concluded that TRIOL treatment with levofloxacin will be an alternative to the triple treatment with clarithromycin as the primary treatment.

Study Overview

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.

Detailed Description

The primary end point in this study is appointed to be "Helicobacter pylori infection eradication with TRIOL treatment" and the secondary end point as "safety". The study involves the investigation of the efficacy and safety of the triple treatment consisting of 500 mg levofloxacin, 1000 mg amoxicillin and 30 mg lansoprazole on Helicobacter pylori eradication in 60 patients with Helicobacter pylori infection.

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.

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
Helicobacter pylori infection eradication
Time Frame: 6 weeks
After 6 weeks from the end of the TRIOL treatment, demonstrating the ratio of patients who do not develop Helicobacter pylori infection by rapid urease test and Giemsa staining.
6 weeks

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
Safety
Time Frame: 6 weeks
During the study all patients will be examined at the determined timepoints in the protocol in regard to any type of clinical adverse event. These examinations involve clinical and laboratory examinations of which the results will be recorded in the final study report and discussed with respect to the current literature.
6 weeks
