HIV I Infection, Tuberculous Meningitis
Conditions
Brief summary
Randomized phase II clinical trial which aims to assess the impact on 3-month mortality and safety of adding adalimumab to standard treatment (anti-tuberculosis drugs and corticosteroids) in HIV patients with tuberculosis meningitis in 3 countries (Brazil, Mozambique, and Zambia).
Detailed description
Phase II multicenter, open-label, randomized, proof of concept, comparative trial with a large alpha (type 1 error rate) to evaluate the impact on 3-month mortality of adding the tumor necrosis factor inhibitor adalimumab to the standard treatment with antituberculosis drugs and high-dose steroids in HIV-infected adults diagnosed with tuberculosis meningitis (TBM) in 3 countries (Brazil, Mozambique, and Zambia). All HIV1-infected patients diagnosed with TBM will be started on standard TB therapy for the duration recommended by national guidelines (2 months intensive phase and 7 months maintenance phase) and high-dose dexamethasone up to 4 weeks. As soon as possible during the first 3 days of the standard TBM treatment that includes antituberculosis treatment and high-dose steroids, consenting patients will be randomized to standard treatment alone or standard treatment + adalimumab. Randomization will be stratified on country and initial severity using the British Medical Research Council (MRC) score. Adalimumab arm: * Standard TBM treatment as described above * Adalimumab 40 mg: one sub-cutaneous injection, every 2 weeks for 10 weeks (total 6 injections), started as soon as possible during the first 3 days of antituberculosis treatment and high-dose steroids As World Health Organization and national guidelines for early antiretroviral therapy (ART) introduction in patients with TBM advise caution, ART will be started after 4 weeks of TB treatment in both arms if patients are clinically improved (but no later than 8 weeks of anti-TB treatment). An interim analysis will be performed after 20 patients have been followed up for 3 months in adalimumab arm. This interim analysis will monitor the safety of adding TNF-inhibitor adalimumab.
