Immunological Biomarkers in Tuberculosis Management (OPTI-4TB)

August 9, 2024 updated by: Hospices Civils de Lyon

Optimization of Tuberculosis Diagnosis and Management Using Four Immunological Biomarkers

Tuberculosis (TB) is the leading cause of death by infectious disease in the world, responsible for 1.6 million deaths in 2017. The treatment of active TB requires at least a 6-month combined antibiotic regimen and can cause heavy side effects. As a consequence, treatment adherence is not optimal, particularly in primary care settings. Rapid and reliable monitoring of anti-TB treatment adherence and efficacy is critical to provide adequate patient care and curb relapse episodes and acquired drug resistance.

Investigators propose to evaluate the performance in terms of diagnosis accuracy and outcome prediction of four new biomarkers of active TB: 1) a double IGRA (Interferon Gamma Release Assay) including QuantiFERON-Gold Plus® and HBHA; 2) a whole blood transcriptomic analysis of mRNA (messenger Ribonucleic acid) expression of a panel of 150 genes; 3) a whole blood proteomic analysis; 4) an ex vivo immunophenotyping using flow and mass cytometry to characterize the lymphocyte populations.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: Active tuberculosis
Other: Multiple blood samples
Patients with active tuberculosis will have 5 research-specific blood samples: V1, (baseline) immediately before initiating anti-tuberculosis treatment, then 4 samples during anti-tuberculosis treatment and follow-up, i.e. at 48 hours (V2), 15 days (V3), 2 months (V4) and 6 months (V5) after initiation of treatment. The total volume of each sample will be 20 mL for a total of 100 mL.
Other: Latent tuberculosis infection
Other: Single blood sample
Patients with Latent tuberculosis infection will have a single specific sample of 14 mL.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Concordance of the kinetics of biomarkers with the evolution of the disease
Time Frame: 6 months

It is a composite outcome. Evolution of the disease is defined by clinical status, radiological computed tomography evolution and negation of the mycobacterial culture of routine respiratory samples.

The biomarkers assessed are:

1) a combination of IGRAs test (QuantiFERON-Gold Plus and HBHA); 2) a transcriptomic signature; 3) a protein signature; 4) a phenotypic signature (by implementing an immunomonitoring approach).
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Analytical characteristics of a combination of 2 IGRAs (QuantiFERON-TB Gold Plus (QFT-P) and HBHA) in the diagnosis / prognosis of tuberculosis disease.
Time Frame: 6 months
Measurement of gamma interferon responses induced by different conditions of ex-vivo stimulation of the blood sample by specific Mtb peptides. This biomarker will be confronted with the evolution of the evolution of the disease as defined in the primary outcome measure.
6 months
Performance of an immunomonitoring test by mass or flow cytometry in the diagnosis / prognosis of tuberculosis by measuring the dynamics of the blood population of T lymphocytes over time.
Time Frame: 6 months
Qualitative and quantitative monitoring of the different subpopulations of immune cells (CD4 + T cells, CD8 +(cluster of differentiation 8) T cells, MAIT, Th1, Th2, Th1, Tfh, Treg, naive, effector and memory cells) during anti-tuberculosis treatment will be carried out. The analytical characteristics (sensitivity, specificity, VPN and VPP) of this immunomonitoring tool will be determined by comparing the abundance of different cellular phenotypes with the evolution of the disease as defined in the primary outcome measure.
6 months
Evaluate the performance of a test based on the interpretation of a transcriptomic signature in plasma in the diagnosis / prognosis of TB.
Time Frame: 6 months

A transcriptomic signature in plasma is a set of genes involved in the immune response specifically deregulated during the different stages of infection and disease progression.

This assessment will be made from blood samples. The transcriptomic signature composed of 16 genes will be evaluated during the anti-tuberculosis treatment and confronted with the evolution of the disease as defined in the primary outcome measure.
6 months
Assess the performance of a test based on the interpretation of a protein signature in the diagnosis / prognosis of tuberculosis.
Time Frame: 6 months

A protein signature is composed of cytokines and chemokines, also deregulated during the various stages of infection and progression of the disease.

This assessment will be made from blood samples. The protein signature composed of cytokines / chemokines of interest (ie IP-10, TNF-a (tumor necrosis factor - a), IL-1(interleukin - 1), IL-18, IL-12, CCL4, IL-2, IFN-g (interferon - g),…) will be evaluated during the anti-tuberculosis treatment and confronted with the evolution of the disease as defined in the primary outcome measure.
6 months
Determine the achievement of target concentrations of rifampicin
Time Frame: 6 months
To determine the achievement of target concentrations of rifampicin the pharmacokinetic profile of rifampicin will be evaluate by a combination of parameters such as the area under the curve, maximum and minimum concentration, clearance, volume of distribution, modeled from three concentration measurements at each visit. (V2, V3 and V4).
6 months
Establish the rate of metabolic self-induction of rifampicin
Time Frame: 6 months
To establish the rate of metabolic self-induction of rifampicin the pharmacokinetic profile of rifampicin will be evaluate by a combination of parameters such as the area under the curve, maximum and minimum concentration, clearance, volume of distribution, modeled from three concentration measurements at each visit. (V2, V3 and V4).
