5. Study Description
Brief Summary
The trial will evaluate the extended bactericidal activity of 14 consecutive days of oral administration of PA-824 at 50, 100, 150 and 200 mg per day in adult patients with newly diagnosed, uncomplicated, smear positive tuberculosis (TB). A control group will receive standard TB treatment.
Detailed Description
The planned sample size of 15 participants per treatment group is in keeping with other Phase II trials of this type and accounts for the possibility of up to 3 drop-outs per arm, which based on previous studies of this type conducted at these sites, represents a conservative estimate of the expected drop-out rate.
