NCT05401071

Brief Summary

Tuberculosis (TB) remains the most important infectious disease in the world. A major barrier to tuberculosis control is poor adherence to long-term and complex treatment regimens. This is a multicenter prospective, non-inferiority randomized controlled study. The purpose of our study is a) to evaluate the tolerability, efficacy and pharmacokinetics/pharmacodynamics (PK/PD) of the high-dose rifapentine, b) to evaluate whether the high-dose rifapentine-containing regimen has the potential to treat the rifampicin-sensitive pulmonary tuberculosis and shorten the course of treatment to 17 weeks. This study is of great significance for shortening the course of treatment, reducing the adverse reactions and economic burden of patients' treatment in rifampicin-sensitive tuberculosis patient.

Outcome Measures

Primary Outcomes (1)

  • Treatment success rate of the short regimen during drug treatment and follow-up.

    To compare the treatment success rate without relapse between the short regimen with rifapentine 10mg/kg, the short regimen with rifapentine 15mg/kg, the short regimen with rifapentine 20mg/kg and the WHO standardized regimen group.

    108 weeks after randomization

Secondary Outcomes (3)

  • The frequency of grade 3 or greater adverse events among patients Over the 108 Week Treatment and Follow-up Period.

    up to 108 weeks

  • Relapse rate during follow-up.

    82-91 weeks after the end of drug treatment.

  • the percentage of participants found to be culture-negative at the end of intensive phase and the end of treatment phase

    8 weeks, 17 weeks and 26 weeks after randomization

Study Arms (4)

Short Regimen with Rifapentine 10mg/kg

EXPERIMENTAL

Intervention: Short Regimen with Rifapentine 10mg/kg consists of two periods of 17- 26 weeks. The first is an intensive phase of 8 weeks, and included rifapentine, isoniazid, pyrazinamide, and moxifloxacin. This is followed by a continuation phase of 9 weeks with the following agents: rifapentine, isoniazid and moxifloxacin (extended up a maximum of 18 weeks if no smear conversion at the end of 8 weeks or the tuberculosis cavity is not closed at the end of 17 weeks).

Other: Short Regimen with Rifapentine 10mg/kg

Short Regimen with Rifapentine 15mg/kg

EXPERIMENTAL

Intervention: Short Regimen with Rifapentine 15mg/kg consists of two periods of 17- 26 weeks. The first is an intensive phase of 8 weeks, and included rifapentine, isoniazid, pyrazinamide, and moxifloxacin. This is followed by a continuation phase of 9 weeks with the following agents: rifapentine, isoniazid and moxifloxacin (extended up a maximum of 18 weeks if no smear conversion at the end of 8 weeks or the tuberculosis cavity is not closed at the end of 17 weeks).

Other: Short Regimen with Rifapentine 15mg/kg

Standardized Regimen

ACTIVE COMPARATOR

Intervention:World Health Organization (WHO) Standardized Regimen group consists of 26 weeks with two phases of treatment. The first is an intensive phase of 8 weeks, and included rifampicin, isoniazid, pyrazinamide, and ethambutol. This is followed by a continuation phase of 18 weeks with the following agents: rifampicin and isoniazid.
