February 17, 2022 updated by: Julius Spicak, Institute for Clinical and Experimental Medicine

The Influence of Laparascopic SLeeve gAstrectomy Vs. Endoscopic Gastric Plication on Body weIght, Metabolic pArameters and Microbiota Composition in Patients With Obesity: Randomized, Open-labelled Study (SLAVIA Trial)

The project will describe the efficacy and safety of laparoscopic sleeve gastrectomy and endoscopic gastric plication procedures as compared to conservative therapy and clarify the mechanisms of action of these treatments. The project will also contribute to more precise indications of bariatric or endoscopic methods in clinical practice and enable personalized choice of therapy for particular patient.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet recruiting

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

Bariatric surgery is the most efficacious treatment of obesity and type 2 diabetes mellitus. Novel endoscopic methods based on the principles of bariatric surgery are also highly effective. No direct randomized comparison of both types of treatment has been performed to date and the mechanisms of action of both procedures are still only partially clarified. The aim of the project is to perform a randomized trial comparing efficacy and safety of three treatment options in patients with obesity: laparoscopic sleeve gastrectomy, endoscopic gastric plication and conservative treatment. A further aim is to characterize the influence of the three treatments on subclinical inflammation, gut microbiota composition and changes of gastrointestinal hormones. The results of the project will describe the efficacy and safety of these procedures as compared to conservative therapy and clarify the mechanisms of action of these treatments. The project will also contribute to more precise indications of bariatric or endoscopic methods in clinical practice and enable personalized choice of therapy for particular patient.

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
75

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.

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.
