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.

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
Change from baseline OLGA/OLGIM stages of gastric mucosa
Time Frame: At the first, seventh and thirteenth month of treatment
Assessment of OLGA/OLGIM stages by GI pathologists. The obtained biopsy specimens will be scored using visual analogue scale (0, 1, 2, 3 points for none, mild, moderate and severe, respectively) to evaluate gastroatrophy and gastrointestinal metaplasia
At the first, seventh and thirteenth month of treatment
Change from baseline gastric mucosal status under gastroscope
Time Frame: At the first, seventh and thirteenth month of treatment
Assessment of Kimura-Takemoto classification by endoscopy. The variation of atrophy can reflect the extent and degree of atrophy. The severity of atrophy increases gradually with C1-C2-C3-O1-O2-O3. Cases of closed-type gastric mucosa atrophy have an atrophic boundary between the fundic mucosa and the pyloric mucosa in the antrum or less curvature of the gastric body. Cases of open-type gastric mucosa atrophy have an atrophic boundary in the lateral wall or greater curvature of the gastric body. C, closed; O, open
At the first, seventh and thirteenth month of treatment

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
Change from baseline blood test result
Time Frame: At the first, seventh and thirteenth month of treatment
Assessment of Gastrin-17 and Pepsinogen I/II
At the first, seventh and thirteenth month of treatment
Incidence of adverse reactions
Time Frame: Through follow-up period completion, an average of 1 year
Assessment of incidence of adverse reactions
Through follow-up period completion, an average of 1 year

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
