Efficacy and Safety of a Triple Eradication Scheme for Helicobacter Pylori Based on Tegoprazan vs Esomeprazole

March 12, 2024 updated by: Yoali Maribel Velasco Santiago, Hospital General de México Dr. Eduardo Liceaga

Efficacy and Safety of a Triple Eradication Scheme for Helicobacter Pylori Based on Amoxicillin 1g + Clarithromycin 500 mg and Tegoprazan 50 mg vs Amoxicillin 1g + Clarithromycin 500 mg and Esomeprazole 40 mg Twice a Day for 14 Days

In Mexico, quadruple therapy is used to treat Helicobacter pylori (H.P.) at the expense of greater adverse effects, costs, and lower adherence to treatment. According to evidence, a competitive potassium channel blocker (P-CAB) is non-inferior to a proton pump inhibitor (PPI) and can improve the eradication rate of H.P. while maintaining triple therapy antibiotics (amoxicillin-clarithromycin) without increasing adverse effects, fewer drugs and better adherence to treatment. It is proposed to study the effect of a P-CAB in the eradication of H.P. as part of a triple therapy in Mexican patients, assuming that the efficacy and safety of a triple therapy of amoxicillin-clarithromycin-tegoprazan will be superior to amoxicillin-clarithromycin-esomeprazole.

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

160 patients with a diagnosis of H.P. infection with indication for treatment in accordance with the IV Mexican Consensus on Helicobacter Pylori, evaluated in the Gastroenterology outpatient clinic, will be recruited. Participants will be randomized into two groups, one group will receive tegoprazan 50 mg BID, clarithromycin 500 mg BID and amoxicillin 1 gr BID for 14 days and the second group will receive esomeprazole 40 mg BID, clarithromycin 500 mg BID and amoxicillin 1 gr BID for 14 days. Through complementary studies, telephone calls and application of questionnaires, adherence to treatment will be evaluated and adverse events will be monitored, and once the treatment period is completed, a breath test will be performed between days 28-42 to verify eradication, thereby evaluating effectiveness.

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.

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
Response to treatment by determining the eradication rate
Time Frame: Two months
The eradication rate will be measured by a carbon-13 urea breath test that will verify the eradication of Helicobacter pylori. The eradication rate of the triple regimen based on clarithromycin - amoxicillin - esomeprazole vs clarithromycin - amoxicillin - tegoprazan will be compared.
Two months
Compared Treatment-related adverse events
Time Frame: Two months
Treatment-related adverse events will be evaluated by complementary serum studies and interrogated according to system organ classes and preferred terms using MedDRA. Adverse events related to the treatment of the triple regimen based on clarithromycin - amoxicillin - esomeprazole vs clarithromycin - amoxicillin - tegoprazan will be compared.
Two months

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
Brief Medication Questionnaire
Time Frame: Two weeks
Identify the factors associated with medication consumption, by applying the Brief Medication Questionnaire on day 7 and 14 of treatment, via telephone call and in person.
Two weeks
Percentage of patients with adherence to treatment
Time Frame: Two weeks
Adherence to treatment will be evaluated by calculating the percentage of compliance and tablet count, which is based on the count of the number of tablets left in the container compared to the amount initially indicated, and the time between the indication and the count. The percentage of adherence to eradication treatment will be compared in patients treated with the scheme based on tegoprazan vs. proton pump inhibitor.
Two weeks
Report all Treatment-related adverse events
Time Frame: Two months
Treatment-related adverse events will be evaluated by complementary serum studies and interrogated according to system organ classes and preferred terms using MedDRA.
