Effectiveness of a bedaquiline, linezolid, clofazimine 'core' for multidrug-resistant TB.

ABSTRACT:

Background

Treatment outcomes may be compromised among individuals with multidrug/rifampicin-resistant TB (MDR/RR-TB) with fluoroquinolone (FQ) resistance. Among people in whom an FQ was unlikely to be effective, we compared the effectiveness of longer individualised regimens comprised of bedaquiline (Bdq) for 5-8 months, linezolid, and clofazimine to those reinforced with at least 1 Group C drug and/or longer Bdq duration.

Methods

We emulated a target trial to compare the effectiveness of initiating and remaining on the core regimen to a regimen reinforced with 1) Bdq for ≥9 months, 2) Bdq for ≥9 months, and delamanid (Dlm), 3) imipenem (Imp), 4) a second-line injectable, or 5) Bdq for ≥9 months, Dlm and Imp. We used cloning, censoring, and inverse-probability weighting to
