Brief Summary:

Tuberculous (TB) meningitis is the most severe manifestation of TB infection, leaving up to 50% of patients dead or neurologically disabled. Current treatment is similar to treatment of lung TB, although penetration of some antibiotics into the brain is poor and the immune-pathology of TB meningitis is very different from pulmonary TB. In a recent phase II clinical trial from the investigators group, the first of its kind globally, intensified antibiotic treatment, with moxifloxacin and high dose rifampicin, strongly reduced mortality of TB meningitis.

The investigators aim to examine the effect of intensified antibiotic treatment on mortality and morbidity of TB meningitis in a phase 3 clinical trial, preceded with an explorative pharmacokinetic (PK) study to examine if higher oral doses rifampicin result in exposures similar to the i.v. dose used in our phase 2 trial, since oral rifampicin could be implemented much easier in low-resource settings.

Condition or disease Intervention/treatment Phase
Tuberculous Meningitis Drug: Rifampicin intravenous Drug: Oral rifampicin Phase 2

Detailed Description:


In a recent clinical trial the investigators have shown that a higher dose of rifampicin administered intravenously (600 mg iv) during the first 2 weeks of treatment is safe and associated with a survival benefit in adults with TB meningitis. An oral (rather than iv) dose would help implementation of intensified treatment for TB meningitis. However, it is hard to predict what oral dose of rifampicin will result in rifampicin exposures similar to 600 mg iv, due to differences in bio-availability (oral vs. iv) and the unpredictable dose-concentration relationship (nonlinear pharmacokinetics of rifampicin). Therefore the investigators aim to examine the pharmacokinetic of 2 higher doses of rifampicin (750 mg and 900 mg) given orally, and compare the pharmacokinetic profiles with the result of our previous study using 600 mg rifampicin iv.

General Objective:

To help establish the optimized treatment regimen for TB meningitis

Specific Objectives:

  1. To explore whether exposures resulting from oral rifampicin 750 mg or 900 mg are similar to exposures after intravenous rifampicin 600 mg during the first two days of treatment
  2. To explore whether exposures resulting from oral rifampicin 750 mg or 900 mg are similar to exposures after 14 days of treatment (stabilized rifampicin concentrations, i..e steady-state)
  3. To evaluate the safety and tolerability of high dose of oral rifampicin
  4. To evaluate neurological response and mortality after 2 weeks of treatment with high dose rifampicin

Study Design:

Explorative pharmacokinetic study; randomized, three-arm, two-period evaluation.

Study procedure:

After diagnosis of TB meningitis, eligible patients will be randomized to get either oral 750 mg, oral 900 mg, or iv 600 mg rifampicin for 14 days in combination with standard oral TB drugs (isoniazid 300 mg/day, ethambutol 750 mg/day, and pyrazinamide 1500mg/day) and adjuvant dexamethasone i.v. and pyridoxine.

Serial blood samples will be taken 6 times from 0, 1, 2, 4, 8, and 12 hour after drug administration at the first or second day of treatment and at day 14 (steady-state). Single cerebrospinal fluid (CSF) sample will be taken 3-6 hours after administration at the same day of blood sampling days.

Study Start Date : June 2013
Actual Primary Completion Date : October 2013
Actual Study Completion Date : April 2014

Arm Intervention/treatment
Active Comparator: Rifampicin 600 mg
Subjects in this arm receive 600 mg rifampicin intravenously
Drug: Rifampicin intravenous
Other Name: Rifadin

Experimental: rifampicin 750 mg
Subjects in this arm receive 750 mg rifampicin orally
Drug: Oral rifampicin
Other Name: Rifampisin (Kimia Farma, Bandung, Indonesia)

Experimental: rifampicin 900 mg
Subjects in this arm receive rifampicin 900 mg orally
Drug: Oral rifampicin
Other Name: Rifampisin (Kimia Farma, Bandung, Indonesia)

Primary Outcome Measures :
  1. Pharmacokinetic profile of several rifampicin dose [ Time Frame: Day 2 and Day 14; 6 time points for blood analysis, and 1 time point for CSF analysis ]
    We will measure plasma drug concentration at hour 0, 1, 2, 4, 8, and 12, while CSF drug concentration will be measured at a single time point i.e. at hour 3-6 post dose. The sampling days will be (1) within the first three days, and (2) at day 14 of the intensified treatment.

Secondary Outcome Measures :
  1. mortality [ Time Frame: early (1 month) and late (6 months) ]
    We will measure early and late mortality
