Rifapentine-Based Shorter Regimens for Tuberculosis and TB Infection in Kazakhstan

RIFA-REAL is a prospective observational longitudinal study evaluating the safety, feasibility, and effectiveness of rifapentine-based shorter treatment regimens for drug-susceptible tuberculosis (DS-TB) and tuberculosis infection (TBI) under routine programmatic conditions in Kazakhstan. The study enrolls three cohorts: patients with DS-TB receiving the 4-month isoniazid-rifapentine-moxifloxacin-pyrazinamide regimen (2HPMZ/2HPM), patients with DS-TB receiving the standard 6-month isoniazid-rifampicin-pyrazinamide-ethambutol regimen (2HRZE/4HR), and individuals with TBI receiving the 1-month rifapentine-isoniazid regimen (1HP). Participants include people living with and without HIV. The study is conducted across four regions of Kazakhstan and is funded through the Western-Eastern European Partnership Initiative on HIV, Viral Hepatitis and TB (WEEPI) grant. Findings will inform national TB policy and contribute to global evidence on programmatic implementation of rifapentine-based regimens.
