Evaluation of Acacia Gum on Microbiome and Bowel Function in Participants With Chronic Constipation

January 11, 2021 updated by: Alpinia Laudanum GmbH

An Exploratory Pilot Study to Evaluate the Impact of Alpinia Acacia Gum on Microbiome and Bowel Function in Subjects With Chronic Constipation

Proof of concept study to investigate the impact of a food supplement consisting of Acacia gum on changes of gut microbiota and production of short chain fatty acids. Additionally, safety, tolerability and parameters of bowel function (stool frequency, stool consistency and gastrointestinal symptoms) will be assessed during the study.

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.

Ages Eligible for Study

21 years to 56 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female
