IMPAACT 2034 is a Phase I, multi-site, open-label, pharmacokinetic (PK), safety, tolerability, and acceptability study of a single-dose of pretomanid (Pa) in infants, children, and adolescents less than 18 years of age living with or without HIV and confirmed or probable rifampicin-resistant tuberculosis. Participants will be given a single-dose of pretomanid, added to their TB treatment regimen, with intensive PK sampling. After receiving the single dose of Pa, participants will be followed for two weeks for safety.

Site selection was completed in March 2022 and was open to all IMPAACT sites; protocol-specific sites and sites affiliated with other NIH-supported HIV research networks with experience with tuberculosis studies were also invited to participate. Planned sites are located in Brazil, India, South Africa, Tanzania, and Thailand.
