Key inclusion & exclusion criteria
|
Inclusion Criteria:
- Adult (age 18 years and older) with documented positive TST (or in the absence of TST,
a documented positive QFT) and prescribed 9 months of Isoniazid for LTBI, following
authoritative recommendations.
Exclusion Criteria:
- Patients who were contacts of TB cases known to be resistant to Isoniazid, Rifampin,
or both.
- Known HIV-infected individuals on anti-retroviral agents whose efficacy would be
substantially reduced by Rifampin, unless therapy can safely be changed to agents not
affected by Rifampin.
- Pregnant women - Rifampin and Isoniazid are considered safe in pregnancy but therapy
is usually deferred until 2-3 months post-partum to avoid fetal risk and the potential
for increased hepato-toxicity immediately post partum.
- Patients on any medication with clinically important drug interactions with Isoniazid
or Rifampin, which their physician believes would make either arm contra-indicated.
- Patients with a history of allergy/hypersensitivity to Isoniazid or to Rifampin,
Rifabutin or Rifapentine.
- Patients with active TB. Patients initially suspected to have active TB can be
randomized once this has been excluded.
- Patients who have already started LTBI therapy.
