Clinical Trials

01/01/2020 - 08/30/2022

CHIP-TB Trial (Child Home Initiated Preventive treatment for TB)

Funded by UNITAID and the IMPAACT4TB project, this cluster-randomized trial will compare home-based vs clinic-based evaluation and initiation of TB preventive therapy (3RH or 3HP) in child TB contacts less than 15 years of age in Ethiopia and South Africa. This includes pre and post-trial qualitative assessments and a cost-effectiveness evaluation.

Principle Investigator 


Phase I/II Dose Finding, Safety and Tolerability Study of Daily Rifapentine Combined with Isoniazid (1HP) for Tuberculosis Prevention in Infants, Children and Adolescents

IMPAACT 2024 will study the PK and safety of 1HP, or one month of weekly rifapentine and isoniazid for TB prevention. This study will also assess drug interactions with dolutegravir and efavirenz in children living with HIV.
