NCT00128206

Brief Summary

The purpose of this study is to determine whether an alternative drug, (rifampin) given daily, is better at treating tuberculosis (TB) and more tolerable than the usual drug treatment, isoniazid (INH). Study participants will include 972, TB infected, San Francisco Jail inmates, aged 18 or older. One group of volunteers will take INH two times a week for 9 months, and the other group will take rifampin daily for 4 months. Medication will be administered in jail and at the San Francisco TB Clinic if the volunteer is released from jail prior to completing the study. Participants will be seen daily for 4 months (rifampin group), and 2 times a week for 9 months (INH group) for directly observed therapy. Study procedures will include 5 symptom review visits and blood samples for lab testing. Follow-up will continue for each subject for five years after enrollment into the study.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Laboratory Test or Clinical Judgment Resulting in the Need to Stop Study Medication

    Liver function tests were taken at regular intervals and clinical symptoms were reviewed at regular intervals in both study groups. On the basis of these tests and examinations, physicians determined whether the study drug needed to be stopped.

    up to one year

Secondary Outcomes (2)

Limitations and Caveats

Initial enrollment estimates were not met, from lower TB rates, increased deportation rates and fewer Jail personnel for LTBI testing. The complexity of treatment in the jail led to technical problems in the analytic plan.
