NCT00023452

Brief Summary

Open-label, multi-center, Phase III clinical trial to compare the effectiveness and tolerability of a three-month (12-dose) regimen of weekly rifapentine and isoniazid (3RPT/INH) to the effectiveness of a nine-month (270-dose)regimen of daily isoniazid (9INH) to prevent tuberculosis (TB) among high-risk tuberculin skin-test reactors, including children and HIV-infected persons, who require treatment of latent TB infection (LTBI).

Outcome Measures

Primary Outcomes (1)

  • Cumulative Rate of Culture-Confirmed TB Disease in Participants ≥18 Years of Age AND Culture-Confirmed or Probable (Clinical) TB Disease in Participants Less Than [<]18 Years of Age at 33 Months After Enrollment

    Cumulative TB disease rate defined as number of participants ≥18 years old with culture-confirmed TB disease (defined as positive culture for Mycobacterium tuberculosis \[MTB\]) and those \<18 years old with probable (clinical) TB disease (defined as objective evidence of clinical TB disease \[cough, fever, night sweats, weight loss, or hemoptysis\] based on history or physical exam plus radiograph, computed tomography \[CT\] scan, other diagnostic tests PLUS response to antituberculosis therapy AND objective improvement of radiograph or other diagnostic tests; OR evidence of granuloma with organism positive for acid-fast bacilli \[AFB\], or caseating granulomata at autopsy or biopsy) between enrollment and the 990th Day of the Trial (33 months after enrollment, or end of the trial) per 100 participants with (w/)33 months of follow-up calculated using survival analysis methods (Kaplan-Meier approach).

    Baseline up to Month 33

Secondary Outcomes (14)

  • Cumulative Rate of Culture-Confirmed TB Disease in Participants ≥18 Years of Age AND Culture-Confirmed or Probable (Clinical) TB Disease in Participants <18 Years of Age at 24 Months Following Completion of Study Therapy

    Baseline up to Month 27 (3RPT/INH) or Month 33 (9INH)

  • Cumulative Rate of Culture-Confirmed or Probable (Clinical) TB Disease (Regardless of Age) At 33 Months After Enrollment

    Baseline up to 33 Months

  • Percentage of Participants With Drug Discontinuation Due to Adverse Drug Reactions Associated With 3RPT/INH or 9INH

Eligibility Criteria

Age2 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Males or nonpregnant, non-nursing females \> 2 years old.
  • Tuberculin (PPD) skin test reactors at high risk for developing TB but without evidence of active TB. High-risk reactors are defined as:
  • Household and other close contacts of persons with culture-confirmed TB who are TST-positive as part of a contact investigation conducted within two years of the date of enrollment. Close contact is defined as \> 4 hours in a shared airspace during a one-week period. Among close contacts, a positive TST is defined as \> 5 mm induration after 5 TU of PPD placed intradermally using the Mantoux technique.
  • TST converters--converting from a documented negative to positive TST within a two-year period. This is defined as persons with a tuberculin skin test of \> 10 mm within two years of a nonreactive test or persons with an increase of \> 10 mm within a two-year period.
  • HIV-seropositive, TST positive (\> 5 mm induration) persons.
  • Persons with \> 2 cm2 of pulmonary parenchymal fibrosis on chest X-ray, no prior history of TB treatment, \> 5 mm induration on TST, and 3 sputum cultures negative for M. tuberculosis on final report.
  • HIV-seropositive close contacts of persons with culture-confirmed TB, regardless of TST status. In addition, HIV-seropositive close contacts of persons with culture-confirmed TB who have a documented history of completing an adequate course of treatment for active TB or latent TB infection, are also eligible.
  • Willing to provide signed informed consent, or parental consent and participant assent.

You may not qualify if:

  • Current confirmed culture-positive or clinical TB
  • Suspected TB (as defined by the site investigator)
  • Tuberculosis resistant to isoniazid or rifampin in the source case
  • A history of treatment for \> 14 consecutive days with a rifamycin or \> 30 consecutive days with INH during the previous 2 years.
  • A documented history of a completing an adequate course of treatment for active TB or latent TB infection in a person who is HIV-seronegative.
  • History of sensitivity/intolerance to isoniazid or rifamycins
  • Serum aminotransferase aspartate (AST, SGOT) \> 5x upper limit of normal among persons in whom AST is determined
  • Pregnant or nursing females
  • Persons currently receiving or planning to receive HIV-1 protease inhibitors or nonnucleoside reverse transcriptase inhibitors in the first 90 days after enrollment.
  • Weight \< 10.0 kg
