What is IMPAACT 2024?

IMPAACT 2024 is a Phase I/II, multi-site, open-label, dose finding and safety study of children less than 15 years of age who qualify for TB preventive therapy. The study is designed to determine the weight-banded dosing, safety and tolerability of rifapentine (RPT) as part of the once-daily, 28-day regimen of isoniazid (INH) and RPT (1HP). Children will be enrolled in age cohorts and both children living with and not living with HIV will be included in each age cohort. Children living with HIV must be receiving dolutegravir (DTG) or efavirenz (EFV) as part of their antiretroviral treatment regimen.
