A Study to Evaluate the Effect of Probiotic Supplement on Quality of Life

Study Overview
=================
Brief Summary
-----------------
This study aims to evaluate the impact of a specific oral probiotic blend on the quality of life of adults with respiratory conditions.

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.

Participants on oxygen therapy. Received a vaccine for COVID-19 in the 2 weeks prior to screening or during the study period, current COVID-19 infections, or currently have the post COVID-19 condition as defined by World Health Organization (WHO) (i.e., individuals with a history of probable or confirmed SARS-CoV-2 infection, usually 3 months from the onset of COVID-19 with symptoms that last for at least 2 months and cannot be explained by an alternative diagnosis).

Major surgery in 3 months prior to screening or planned major surgery during the course of the study. Participant has consumed probiotic supplements and is unwilling to stop at least one week prior to screening and throughout the study. Supplemental probiotics may include standalone probiotic supplements, vitamins with probiotics, and any foods supplemented with probiotics. Participant is currently being prescribed antibiotics or states that they have been prescribed antibiotics within the 3 months prior to screening. Participant has consumed supplemental enzymes and are unwilling to stop at least one week prior to screening and throughout the study. Supplemental enzymes may include standalone enzyme supplements, probiotic supplements with enzymes, and any medications containing enzymes. Participant has an abnormality or obstruction of the gastrointestinal tract precluding swallowing (e.g. dysphagia) and digestion (e.g. known intestinal malabsorption, celiac disease, inflammatory bowel disease, chronic pancreatitis). Participants who are lactating, pregnant or planning to become pregnant during the study. Have a known sensitivity, intolerability, or allergy to any of the study products or their excipients, or any of the rescue medications. Receipt or use of an investigational product in another research study within 28 days prior to baseline visit.
