Intensified Tuberculosis Treatment to Reduce the Mortality of Patients With Tuberculous Meningitis

RecruitingPhase 3

Sponsor: ANRS, Emerging Infectious Diseases

Conditions: Tuberculous Meningitis

Interventions: Aspirin, Placebo of aspirin, WHO TBM treatment, Intensified TBM treatment

Countries: Côte d’Ivoire, Madagascar, South Africa, Uganda

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.

Eligibility criteria

Inclusion criteria:

1. Age ≥ 15 years
2. TBM defined as "definite", "probable" or "possible"
3. Signed Informed Consent

* Definite TBM = at least one of the following criteria: acid-fast bacilli seen in CSF microscopy, positive CSF M. tuberculosis culture, or positive CSF M. tuberculosis commercial nucleic acid amplification test.
* Probable TBM = total modified Marais score ≥12 when neuroimaging is available, or ≥10 when neuroimaging is not available (at least 2 points should come from CSF or cerebral imaging criteria).
* Possible TBM = total modified Marais 6-11 when neuroimaging is available, or 6-9 when neuroimaging is not available.

Exclusion criteria:

* \> 5 days of TB treatment
* Renal failure (eGFR\<30 ml/min, CKD-EPI formula).
* Neutrophil count \< 0.6 x 109/L.
* Hemoglobin concentration \< 8 g/dL.
* Total bilirubin \> 2.6 times the Upper Limit of Normal
* Platelet count \< 50 x 109/L.
* ALT \> 5 times the Upper Limit of Normal.
* Clinical evidence of liver failure or decompensated cirrhosis.
* For women: more than 17 weeks pregnancy or breastfeeding.
* For patients without decrease level of consciousness (Glasgow Coma Scale = 15): Peripheral neuropathy scoring Grade 3 or above on the Brief Peripheral Neuropathy Score (BPNS).
* Documented M. tuberculosis resistance to rifampicin.
* Positive gram-stain, bacterial culture or cryptococcal antigen in the Cerebral Spinal Fluid.
* Evidence of active bleeding (hemoptysis, gastrointestinal bleeding, hematuria, intracranial bleeding).
* Inability to collect Cerebral Spinal Fluid, except for patients with confirmed tuberculosis (by rapid molecular test or culture) from another biological sample and clinical and/or CT scan evidence of meningitis.
* Major surgery within the last two weeks prior to inclusion.
* Ongoing chronic aspirin treatment (eg for cardiovascular risk).
* Current use of drugs contraindicated with study drugs and that cannot be safely stopped (see Appendix 1: Drugs contra-indicated with study drugs).
* In available history from patients:

* Evidence of past intracranial bleeding.
* Evidence of past of peptic ulceration.
* Evidence of recent (\< 3 month) gastrointestinal bleeding.
* Known hypersensitivity contraindicating the use of study drugs .
* Evidence of porphyria.
* Evidence of hyperuricemia or gout.
* Any reason which at the discretion of the investigator would compromise safety and cooperation in the trial.
