Brief Summary  
This is a multicenter, randomized, open-label, rater-blind, active-controlled, interventional Phase 3 study in male and female participants aged 15 years or older and newly diagnosed with MB leprosy.
This study aims to demonstrate if the efficacy of the 24-week bedaquiline-containing MDT regimen is non-inferior to that of the 48-week WHO SOC MDT in participants with MB leprosy.

Primary Objective -
To demonstrate the efficacy of the 24-week bedaquiline-containing MDT (bedaquiline with RMP and CFZ) for the treatment of MB leprosy compared to the 48-week WHO SOC MDT (RMP, CFZ, and DDS) at 52 weeks after start of treatment as rated by the blinded, independent Adjudication Committee (AC).

Primary Outcome - 
Favorable clinical response based on improvement of leprosy skin characteristics, as determined by the blinded, independent AC using a standardized skin assessment, at 52 weeks after start of treatment.

Key Secondary Objective -
To evaluate the efficacy of a 24-week bedaquiline-containing MDT for the treatment of MB leprosy compared to the 48-week WHO SOC MDT at 52 weeks after start of treatment as rated by the blinded onsite clinical rater.

Key Secondary Outcome - 
Favorable clinical response based on improvement of leprosy skin characteristics, as determined by the blinded onsite clinical rater using a standardized skin assessment, at 52 weeks after start of treatment.
