About this study

Official title: Pilot Clinical Trial, Double-blind, Randomized, Placebo Controlled and Masked to Evaluate the Tolerability and Immunogenicity of Nyaditum Resae® Probiotic Administered to Adults With or Without Latent Tuberculosis Infection

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.

Read the detailed description

The incidence of tuberculosis is still a problem of the first magnitude. Every year 1.5 million people die; there are 10 million cases of illness and 100 million new infected. The growing problem of multiresistance is to be added, remaining so prevalent: 700,000 patients, a figure that increases annually with 100,000 people. Prevention of tuberculosis is currently very difficult because it is a disease caused by a bacillus (Mycobacterium tuberculosis) that is transmitted by air: No risk factor for becoming infected has been identified and there is still no prophylactic vaccine that prevents from infection. One of the most characteristic aspects of tuberculosis is that the majority (90-95 %) of people without immunity alterations do not develop the disease after being infected. As for people who do develop the disease, it is still not known why they develop it.

A group of researchers from the Institut Germans Trias i Pujol recently discovered a mechanism that explains this trend. In short, what happens is that certain people create a too strong inflammatory response against tuberculosis bacillus, which ends up creating massive destruction of the tissue that is around the bacillus and brings the characteristic lesion of tuberculosis: tuberculous cavity.

This group of researchers was devising ways to "reeducate" the immune system against the bacillus not make it aggressive. And they did it using two instruments. The first one, an environmental mycobacteria, namely a bacillus of the family of mycobacteria tuberculosis, that usually lives in the water they drink, so that at a greater or lesser extent the investigators already have it in their intestinal flora. The second, inducing a tolerant response, like the investigators do when they eat food. To induce a tolerant response, low and repeated doses of the product make the immune system of the digestive duct "used to" their presence. Thus, when it becomes to find the product, the immune system reacts in a very light and balanced manner, avoiding excessive inflammatory responses. The clearest example is the fact that their immune system "is used" to feed proteins and generates no rejection answers found in the intestinal mucosa.

Hence comes the probiotic Nyaditum resae®, a preparation in the form of drinkable vials, containing a heat-killed environmental mycobacteria and thus can generate a cross-immunity with the tuberculosis bacillus. By giving low and repeated dose to generate a tolerant response, which happens when there is an infection by Mycobacterium tuberculosis, so that a balanced immune response is triggered able to reduce the risk of developing active tuberculosis.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from Baseline in Specific Treg memory cells at week 1 (time frame: From Baseline to Week 1). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02076139, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Oct 2018.
