Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

INTENSE-TBM is randomized controlled, phase III, multicenter, 2 x 2 factorial plan superiority trial assessing the efficacity of two interventions to reduce mortality from tuberculous meningitis (TBM) in adolescents and adults with or without HIV-infection in sub-Saharan Africa:

* Intensified TBM treatment with high-dose rifampicin and linezolid, compared to WHO standard TBM treatment.
* Aspirin, compared to not receiving aspirin. The trial will be open-label for anti-TB treatment and placebo-controlled for aspirin treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Settings: Côte d'Ivoire, Madagascar, Uganda, South Africa.

Follow-up: Participants will be followed up for 40 weeks.

Sample size: 768 patients (192 in each arm).

Primary analysis: We will use a Cox proportional hazard ratio model to compare intensified TB treatment with WHO standard TB treatment, and aspirin with placebo, adjusting for the initial stratification variables (trial country, HIV status, British Medical Research Council \|BMRC\] severity grade). The primary analysis will be conducted in the intention to treat population.

Sub-studies:

* The PK-PD sub-study will take place in the 4 participating countries, and involve 40 participants in total.
* The Multi-Omics sub-study will only take place in South-Africa. It will involve 160 participants in this country.

Participants in each sub-study will sign a specific informed consent.
