High-dose rifapentine for TB during pregnancy and breastfeeding

Rifapentine in High Doses in Pregnancy with TB (Radiant-Moms) study

NIH-funded research Columbia University Health Sciences · NIH-11173908

This project looks at whether giving higher doses of the TB medicine rifapentine is acceptable and safe for pregnant and breastfeeding people with TB, including those living with HIV.

What this research studies

You would be asked about your preferences and choices around TB treatment in pregnancy and breastfeeding using structured choice questions that present realistic treatment trade-offs. The team will use a discrete choice experiment (DCE) with pregnant and breastfeeding people and health care providers in TB-endemic countries to learn what matters most when picking a TB regimen. The work focuses on barriers to using a newer, shorter rifapentine-based regimen and on concerns about dosing and safety for mothers and babies. Results will be used to design future dosing and safety studies and to guide policy so pregnant and breastfeeding people can access appropriate TB options.

Who could benefit from this research

Good fit: Ideal participants are pregnant or breastfeeding people diagnosed with active TB (many may also be living with HIV), especially those living in TB-endemic regions in Africa and Asia.

Not a fit: People who are not pregnant or breastfeeding, do not have TB, or live outside the study countries are unlikely to benefit directly from this specific project.

Why it matters

Potential benefit: If successful, this work could help expand access to shorter rifapentine-based TB treatments for pregnant and breastfeeding people by informing safer dosing and policy decisions.

How similar studies have performed: Shorter rifapentine-based TB regimens have worked well in non-pregnant adults, but studies of high-dose rifapentine and use in pregnant and breastfeeding people are limited, so this approach addresses a new gap.
