Safety and Immunogenicity of Nyaditum Resae® Probiotic to Protect From Tuberculosis

This is a double-blind, masked, compared with placebo clinical trial in healthy volunteers with or without tuberculosis infection. This trial aims to study the effect of the probiotic Nyaditum resae® at the level of specific Regulatory T cells (Treg) memory cells one week after the first administration and the global tolerability of the treatment. Nyaditum resae® is a preparation in the form of drinkable vials containing heat-killed environmental mycobacteria. The overall objective of the study is the effect of Nyaditum resae® on immunity, which could reduce the risk of developing active tuberculosis.
