Study Arms (1)

R35HZE

EXPERIMENTAL

Participants treated with rifampicin at a dose of 35 mg per kilogram of body weight per day, added to the standard doses of isoniazid, pyrazinamide and ethambutol.

Drug: Rifampin

Interventions

The target dose of 35mg/kg will be reached supplementing fixed-dose combination tablets (standard dose) with rifampin-only tablets.

Also known as: Rifampicin
R35HZE
