Tuberculosis | Rifampin and Nevirapine Interactions in Young Children

Tuberculosis research study

What is the primary objective of this study?

Nevirapine is the preferred nonnucleoside reverse transcriptase inhibitor (NNRTI) for treatment of HIV in children younger than 3 years old who have tuberculosis (TB) coinfection. However, there is very limited data on the drug-drug interactions between rifampin and nevirapine in children of this age group. The purpose of this study is to determine the effect of rifampin-containing anti-TB treatment on the blood levels of nevirapine in young children with HIV and TB coinfection. Also, the study will find out whether checking the genetic makeup of a child could help to determine the appropriate dose of nevirapine in the setting of concomitant anti-TB treatment.

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
