Eligibility

Inclusion criteria

Inclusion criteria: 1. Fifteen years and older, on the day of signing the ICF/assent. 2. Has presence of AFB in any SSS taken at screening from a skin lesion from which a biopsy can be taken. 3. Has at least 3 skin lesions, consistent with MB leprosy, of which 2 measure at least 5 cm in diameter. OR at least 10 nodules/lepromas, consistent with MB leprosy, of which 2 measure at least 0.5 cm in diameter. OR at least 1 confluent skin lesion, consistent with MB leprosy, which measures at least 8 cm in diameter. 4. Human immunodeficiency virus-infected participants are allowed if the participant: a. Has a documented HIV-positive status prior to screening. b. Started antiretroviral therapy at least 12 weeks before baseline. c. Is on, or switches to, an ART regimen not containing efavirenz at least 4 weeks prior to enrollment. d. Has a CD4+ cell count =200 cells/µL. e. Has no acquired immunodeficiency syndrome (AIDS)-defining illness or did not show severe symptoms of HIV infection that would make the participant a poor candidate for participation in the study. 5. Has a body weight =30 kg

Exclusion criteria

Exclusion criteria: 1. Has the clinical characteristics of leprosy but presenting only with diffuse infiltration without specific lesions. 2. Has active tuberculosis, ongoing leishmaniasis or Chagas disease, or active hepatitis B or hepatitis C. 3. Has a history of or current non-leprosy-related neuropathies that would affect the interpretation of data collected in the nerve function clinical testing. 4. Has any skin disorder that, in the opinion of the investigator, might interfere with the assessment of leprosy skin lesions. 5. Has a relevant medical history or current condition that might interfere with drug absorption, distribution, metabolism, or excretion such as malabsorption syndrome or renal or hepatic disease.
