Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This pilot double-blind randomized controlled trial will test the preliminary efficacy of two doses of a combination of live microbials (probiotics) given to boost the immunity of unvaccinated persons previously infected with SARS-CoV-2.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This pilot double-blind randomized controlled trial will test the preliminary efficacy of two doses (a standard dose and a high dose) of a combination of live microbials (probiotics), currently marketed in food (including products labeled as dietary supplements), given daily for 21 days to boost the immunity of unvaccinated, generally healthy persons ages 18-60 with prior confirmed SARS-CoV-2 infection. Data collected will include demographics, comorbidities, medications, information about prior SARS-CoV-2 infection, and self-reported symptoms and adverse events (AEs). Biospecimens (saliva, nasal wash, blood, and stool) will be collected at baseline and days 21 and 42 for analysis.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Live microbial (Probiotic) consortium OL-1, standard dose

Combination of a standard dose of live microbials (probiotics) taken as a capsule once per day with breakfast for 21 days. Capsules should not be consumed with hot drinks or alcohol.

Group Type EXPERIMENTAL

OL-1, standard dose

Intervention Type DIETARY_SUPPLEMENT

The live microbial components have been present in the food supply, have a long history of safe use in foods, and are already marketed in the United States.

Live microbial (Probiotic) consortium OL-1, high dose

Combination of a high dose of live microbials (probiotics) taken as a capsule once per day with breakfast for 21 days. Capsules should not be consumed with hot drinks or alcohol.

Group Type EXPERIMENTAL

OL-1, high dose

Intervention Type DIETARY_SUPPLEMENT

The live microbial components have been present in the food supply, have a long history of safe use in foods, and are already marketed in the United States.

Placebo for live microbial (probiotic) consortium

Capsule containing inactive ingredients such as a product of potato starch (maltodextrin), but no probiotics, taken once per day with breakfast for 21 days.

Group Type PLACEBO_COMPARATOR

Placebo

Intervention Type DIETARY_SUPPLEMENT

Capsule containing inactive ingredients such as a product of potato starch (maltodextrin), but no probiotics.
