Drug-Drug Interactions Between Rifapentine and Dolutegravir In HIV/LTBI Co-Infected Individuals (RPT-DTG PK Study).
The purpose of this research study is to see if taking medications to prevent tuberculosis (TB) affect the drug levels in blood of a commonly used HIV medication called dolutegravir (DTG) and if an extra dose of DTG is needed during this TB preventive treatment. The other medicines, rifapentine (RPT) and isoniazid (INH), are drugs used to prevent active TB in people who have been exposed to TB. This study will also help us make sure that people tolerate the medicines and that they are safe when given together. In many countries, DTG is the recommended first-line treatment for HIV. DTG, RPT, and INH are proven beneficial treatments for people living with HIV and latent TB, but it is unclear whether these treatments work differently when taken together. Understanding how DTG interacts with the short-term treatment for latent TB (1HP) is very important for delivering both treatments effectively.
