Short Course Rifapentine and Isoniazid for the Preventive Treatment of Tuberculosis(SCRIPT-TB)

Summary

Tuberculosis (TB) remains the most important infectious disease in the world. Preventive treatment plays an important role in successful control of TB. The investigators' previous study showed a 3-month weekly rifapentine and isoniazid regimen had a high protective efficacy but an unsatisfactory completion rate. Therefore, the investigators suppose that a one-month (12-dose) regimen of rifapentine and isoniazid (1RPT/INH) to be equivalent to a 3-month weekly rifapentine and isoniazid regimen with similar efficacy and higher completion rate. Relevant study is lacking in China where the TB burden is high with the incidence rate of 70/100, 000. Silicosis is a risk factor of Mycobacterium tuberculosis infection. This is an open-label, non-randomized clinical trial to evaluate the efficacy and safety of the 1RPT/INH to prevent tuberculosis (TB) compared with those who do not receive preventive treatment among silicotic patients.
