A Clinical Trial to Evaluate the Efficacy of RUTI® to Reduce the Severity of SARS-CoV-2 Infection (COVID-19)

A Phase II/III, Double-blind, Randomized, Placebo-controlled Clinical Trial to Evaluate the Efficacy of RUTI® to Reduce the Severity of SARS-CoV-2 Infection

The aim of this study is to assess the efficacy of the RUTI® vaccine in achieving clinical improvement of COVID-19 symptoms and to evaluate the safety of RUTI® in patients with SARS-CoV-2 infection. The study will include a comparison between placebo and RUTI® vaccine in a 1:1 design.

Study Overview

• Status: Withdrawn
• Conditions: COVID-19
• Intervention / Treatment: Biological: Placebo; Biological: RUTI® vaccine

Detailed Description

Once it has been confirmed that the patient meets the selection criteria, subjects will be randomly assigned to one of the two study groups:

• Experimental group: Administration of RUTI®
• Control group: Administration of Placebo (physiological serum)

This randomization follows a 1:1 ratio. In this way, of the total of 550 subjects who intend to be recruited for this study, 275 will receive the prophylactic treatment, and 275 will receive the placebo treatment.

Neither patient nor the doctor will know if the subject is part of the experimental group or the control group, that is to say, the treatment assignment is blind.

All subjets will receive just one inoculation of treatment (either RUTI® or Pacebo). The standard treatment of COVID-19, if is necessary, will continue after RUTI® administration according to the local guidelines.

All the subjets will be followed for one month after the first day of RUTI® or Placebo treatment.

Description

Inclusion Criteria:

1. Sign the Informed Consent before initiating the selection procedures.
2. Patients infected with SARS-CoV-2 (PCR +) with mild symptoms up to 7 days that do not require hospitalization, from the onset of symptoms. Mild symptoms, defined as the following criteria: cough, headache, fever (>37.5ºC), muscular pain and shortness of breath.

10. Do not have a smartphone.
11. Detection by the investigator of lack of knowledge or willingness to participate and comply with all requirements of the protocol.
12. Any other findings that, at the discretion of the investigator, may compromise compliance with the protocol or that may influence significantly the interpretation or the results of the effects of probiotics.
