A Bedaquiline, Pyrazinamide, Levofloxacin, Linezolid, and Clofazimine Second-line Regimen for Tuberculosis Displays Similar Early Bactericidal Activity as the Standard Rifampin-Based First-line Regimen.

ABSTRACT:

Background

In 2018 the World Health Organization recommended a switch to an all oral bedaquiline-based second-line regimen for treatment of drug-resistant tuberculosis (DR-TB). How these new second-line regimens fare in comparison to first-line regimens for treatment of drug-sensitive tuberculosis (DS-TB) is not well known.

Methods

In this study, we contemporaneously enrolled subjects with DS-TB (n = 31) or DR-TB (n = 23) and assessed their response to therapy with first-line (rifampin, isoniazid, ethambutol, pyrazinamide) or second-line (bedaquiline, pyrazinamide, levofloxacin, linezolid, clofazimine) regimens, respectively.

Results

We found that the early bactericidal activity of first- and second-line regimens was similar during the first 2 weeks of therapy as dete
