In the WHIP3TB trial, researchers hypothesized that, among persons with HIV receiving antiretroviral therapy, treatment completion of weekly rifapentine and isoniazid for 3 months would be superior to 6 months of daily isoniazid, and that annual weekly rifapentine and isoniazid for 3 months would be more effective than a single round.

4,014 persons with HIV who were receiving antiretroviral therapy and did not have active tuberculosis were randomized to receive weekly rifapentine-isoniazid for 3 months, given either annually for 2 years or once, or daily isoniazid for 6 months.

Participants were screened for tuberculosis symptoms at months 0 to 3 and 12 of each study year and at months 12 and 24. Treatment completion rates and the effectiveness of the different regimens were compared.

Short-course, weekly rifapentine and isoniazid for 3 months was associated with much higher treatment completion rates compared with standard daily isoniazid for 6 months.
