About this study

Official title: A Prospective, Randomized, Double-blinded, Placebo-controlled Study Evaluating the Safety and Impact of resB® Lung Support on Quality of Life in Adult Volunteers With Chronic Obstructive Pulmonary Disease or Non-cystic Fibrosis Bronchiectasis

This study aims to evaluate the impact of a specific oral probiotic blend on the quality of life of adults with respiratory conditions.

Read the detailed description

An imbalance and reduction of microbial diversity in the lung microbiota may negatively impact an individual's general health and quality of life. Further, individuals with respiratory conditions may take medications that may alter gut microbiome, which can have a negative impact on outcomes and quality of life. Evidence has emerged that there are interactions between gut and lung microbiomes, demonstrating the opportunity of using oral probiotics to support a healthy gut and/or lung microbiome, and subsequently, the general health and quality of life in this population.

What is this clinical trial studying?

A study testing Probiotic in people with Chronic Obstructive Pulmonary Disease and Non-cystic Fibrosis Bronchiectasis, run by ResBiotic Nutrition, Inc. at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To determine the effect of resB® Lung Support on quality of life (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05523180, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jun 2024.
