New study tracks TB drugs in breastmilk to protect infants
NCT ID NCT05840809
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how tuberculosis (TB) medications travel through a mother's body, into her breastmilk, and to her nursing baby. Researchers will take blood and milk samples from 20 mothers and small blood samples from their infants at several time points after a dose. The goal is to understand drug levels so doctors can better treat TB in breastfeeding women while keeping babies safe.

Who is studied
Breastfeeding women, including those living with HIV, treated for TB will be recruited prospectively from Infectious Diseases clinic (IDI) and IDI Kampala City Council Authority (KCCA) affiliated clinics. The clinics treat pregnant and breast-feeding women infected with TB. We anticipate that 80% of women will be living with HIV. Drug-drug interactions between antiretroviral therapy (ART) and TB drugs could affect the exposure of TB drugs. Data on concomitant medication will be recorded and included as a covariate in the pharmacokinetic analysis. In accordance with national protocol, the infants of mothers diagnosed with TB treatment will receive isoniazid preventive therapy for six months (the duration of the mothers' TB treatment).
