ANTERO-4: VIPUN Gastric Monitoring System in an Erythromycin Model (ANTERO-4)

August 10, 2020 updated by: Prof Dr Jan Tack

ANTERO-4: A Clinical Investigation of the Effects of Erythromycin on Gastric Motility, Assessed With the VIPUN Gastric Monitoring System in Healthy Adults

It has been demonstrated that the VIPUN Gastric Monitoring System (GMS) can discriminate healthy physiological and pharmacologically-inhibited gastric motility, using a codeine-model in healthy adults (S60320 / AFMPS80M0687).

Erythromycin is a gastroprokinetic agent, known to stimulate gastric contractility. A single dose of 200 mg erythromycin has been shown to induce a prolonged period of enhanced phasic contractile activity.

The primary aim of this investigation is to validate the ability of the VIPUN GMS to discriminate between normal and pharmacologically-enhanced fasting gastric motility in healthy adults.

The performance of the VIPUN GMS can be enhanced by data-driven optimization of the VIPUN Motility Algorithm, used to quantify gastric motility.

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.
