  • TBTC Study 31: Rifapentine-containing Tuberculosis Treatment Shortening Regimens

    Sorry, not yet accepting patients

    The purpose of this study is to determine whether one or two four-month regimens of tuberculosis treatment are as effective as a standard six-month regimen for treatment of pulmonary tuberculosis (TB). All three regimens are administered daily, seven days each week, with direct observation of each dose by a health-care worker at least five of the seven days of each week. The standard six-month regimen is two months of isoniazid, rifampin, ethambutol, and pyrazinamide followed by four months of isoniazid and rifampin. The first short regimen is a single substitution of rifapentine for rifampin: two months of isoniazid, rifapentine, ethambutol, and pyrazinamide, followed by two months of isoniazid and rifapentine. The second short regimen is a double substitution of rifapentine for rifampin and moxifloxacin for ethambutol: two months of isoniazid, rifapentine, moxifloxacin, and pyrazinamide, followed by two months of isoniazid, rifapentine, and moxifloxacin. Target enrollment is 2500 participants. Each study participant will remain in the study for 18 months in order to include at least 12 months of evaluation of whether the participant's TB recurs.

  • Evaluating the Safety and Effectiveness of Short-Course Rifapentine/Isoniazid for the Prevention of Active Tuberculosis in HIV-Infected Individuals With Latent Tuberculosis Infection

    Sorry, in progress, not accepting new patients

    HIV-infected people have an increased risk of developing active tuberculosis (TB). The standard course of treatment for TB is 6 to 9 months of isoniazid (INH). A shorter course of treatment may be as effective and potentially increase treatment adherence. This study will compare the safety and effectiveness of a 4-week regimen of rifapentine (RPT) plus INH versus a standard 9-month regimen of INH in HIV-infected people who are at risk of developing active TB.
