May 2, 2021 updated by: AB Biotics, SA

Efficacy and Safety of Lactobacillus Plantarum and Pediococcus Acidilactici as Co-adjuvant Therapy for Reducing the Risk of Severe Disease in Adults With SARS-CoV-2 and Its Modulation of the Fecal Microbiota: A Randomized Clinical Trial

Clinical research focused to evaluate the effect as coadyuvant of a combination of L. plantarum and P. acidilactici in adults positive for SARS-CoV-2 with mild clinical COVID-19 symptoms. Main objective is to evaluate how this combination of probiotics reduce the risk to progress to moderate or severe COVID and associated advantages such as reduce the risk of death. Adittionnally this RCT is launching to explore the benefits of this combination of strains to modulate fecal microbiome and explore how this correlate with clinical improvement.

Detailed Description

Randomized controlled trial (RCT) to evaluate safety and efficacy of Lactobacillus plantarum CECT 30292, Lactobacillus plantarum CECT 7484, Lactobacillus plantarum CECT 7485 y P. acidilactici CECT 7483, one dose a day to reduce the risk of subjects with mild COVID-19 to evolute to moderate or severe disease. As secondary aims this trial is intented to evaluate the effect of this strains combinations to reduce the frequency and severity of gastrointestinal COVID-19 symptoms and lung abnormalities, to reduce the viral load, modulate the levels of IgG/IgM, and positively modify the fecal microbiota.

300 adults, 18 to 60 years, RTq-PCR positive for SARS-CoV-2, with mild COVID-19, and SpO2 > 90%, living in Mexico city (2,200m over the sea level) will be randomized, after sign of informed consent to receive a combintation of Lactobacillus plantarum CECT 30292, Lactobacillus plantarum CECT 7484, Lactobacillus plantarum CECT 7485 y P. acidilactici CECT 7483 one a day orally or placebo for 30 days.

Clinical severity, lung abnormalities (x-rays), viral load, IgG/IgM levels, and fecal microbiome will be evaluated at COVID-19 research center before randomization. Participants will be invited to remain at home and clinical evolution, temperature, SpO2 will be recorder and reported remotely during the 30 days intervention.

On days 15 and 30, participants will be invited to return to COVID-19 research center to take samples to evaluate evolution of viral load, IgG/IgM and fecal microbiome.

During the 30-days intervention period outcomes such as clinical progression, need of hospitalization, admission to Intensive Care Unit and death will be evaluated

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
