Evaluating PK, Tolerability, and Safety of Rifapentine and Isoniazid in Pregnant and Postpartum Women

Tuberculosis Clinical Trial

Official title:
A Phase I/II Trial of the Pharmacokinetics, Tolerability, and Safety of Once-Weekly Rifapentine and Isoniazid in HIV-1-infected and HIV-1-uninfected Pregnant and Postpartum Women With Latent Tuberculosis Infection

Clinical Trial Summary

The purpose of this study was to evaluate the pharmacokinetics (PK), tolerability, and safety of once-weekly doses of rifapentine (RPT) and isoniazid (INH) in HIV-1-infected and HIV-1-uninfected pregnant and postpartum women with latent tuberculosis (TB).

Clinical Trial Description

TB is a major cause of illness and death in women of reproductive age. Pregnant and postpartum women with latent TB are at higher risk of developing active TB. This study evaluated the pharmacokinetics, tolerability, and safety of 12 once-weekly doses of RPT and INH in HIV-1-infected and HIV-1-uninfected pregnant and postpartum women with latent TB. This study enrolled HIV-1-infected and HIV-1-uninfected pregnant women with latent TB and their infants into two cohorts based on gestation. Cohort 1 participants were enrolled in their second trimester (greater than or equal to 14 to less than 28 weeks), and Cohort 2 participants were enrolled in their third trimester (greater than or equal to 28 to less than or equal to 34 weeks). All participants received 12 directly observed once-weekly doses of RPT, INH, and pyridoxine (vitamin B6) at study entry and at 11 weekly follow-up visits. Study researchers would perform an interim analysis to assess the PK of RPT during the study, and a dose adjustment could have been recommended based on this analysis. Study visits occurred at days 0-3, once a week through week 11, and once a month until 24 weeks after delivery. Visits would include physical examinations, obstetrical exams, and blood collection. Infants were followed monthly until 24 weeks after birth. ;
