Monitoring the Efficacy of a Probiotic Dietary Supplement SmartProbio C in Patients With Severe COVID-19 Infection
- Conditions
- COVID-19

- Dietary Supplement: PlaceboDietary Supplement: SmartProbio C
- Registration Number
- NCT05474144
- Lead Sponsor
- Medi Pharma Vision
- Brief Summary
The aim of the study is to test the efficacy of the probiotic SmartProbio C in patients with a severe course of COVID-19 infection. Patients were randomly divided into two arms between the probiotic group and the placebo group. They were further divided into four groups according to 1) BMI (Body mass index; \<=30/\>30), 2) age (\<=65/\>65), 3) CRP (C-reactive protein; \<=100/\>100), 4) chronic lung disease (yes/no). Gut microbiome analysis and its changes in selected parameters (amount of lactobacilli, bifidobacteria, Akkermansia, Proteobacteria, Firmicutes/Bacteroidetes ratio) were chosen as the primary endpoint. Other assessed indicators include:
* Tracking of time to clinical improvement by two points on a seven-point ordinal scale for clinical improvement according to R\&D Blueprint: COVID-19 Therapeutic Trial Synopsis (WHO, 2020) or time to hospital discharge (whichever comes first)
* Monitoring the length of oxygen dependence
* Monitoring of laboratory markers of inflammation - serum peripheral blood CRP levels
* Monitoring of mortality

- Abnormal screening laboratory results - laboratory abnormalities that, in the opinion of the investigator, will interfere with completion of participation in the clinical trial or will interfere with the results of the trial.
- Participation in another clinical trial of a drug or medical device, or less than 30 days have elapsed since the completion of participation in another trial or use of the investigational drug or device.
- Other probiotic supplementation.
- Hypersensitivity to any ingredient of a product administered during a clinical trial.

- Arm && Interventions
Group Intervention Description Placebo Placebo Patients received placebo consisting of purified maltodextrin, one capsule twice a day - mornings and evenings before meal - for a period of 2 weeks. Verum SmartProbio C Patients received probiotic supplement SmartProbio C, one capsule twice a day - mornings and evenings before meal - for a period of 2 weeks.
- Primary Outcome Measures
Name Time Method Gut microbiome The first sample was taken at the beginning of hospitalization before the start of supplementation, the second at discharge from the hospital, but not later than on the 14th day of hospitalization. Changes in selected parameters of gut microbiome (amount of lactobacilli, bifidobacteria, Akkermansia, Proteobacteria, and Firmicutes/Bacteroidetes ratio) were chosen as the primary endpoint.
- Secondary Outcome Measures
Name Time Method CRP (C-reactive protein) monitoring On the first day of admission to hospital and on the day of hospital discharge, but no later than 14th day Monitoring of laboratory marker of inflammation - serum peripheral blood CRP levels
Monitoring the length of oxygen dependence From the beginning of the provision of HFOT (high flow oxygen therapy) to the end of the provision of HFOT Measurement of the time it was necessary to provide HFOT (high flow oxygen therapy) to the patient
Length of hospitalisation From the date of admission to hospital until discharge from hospital or above defined two point improvement, whichever comes first Tracking of time to clinical improvement by two points on a seven-point ordinal scale for clinical improvement according to R\&D Blueprint: COVID-19 Therapeutic Trial Synopsis (WHO, 2020), or time to hospital discharge (whichever comes first).
Monitoring mortality rates From the date of admission to hospital until discharge from hospital or death, whichever comes first The percentage of deaths in the placebo group compared to percentage of deaths in the verum group
