1. I
2. II with a cross-sectional diameter < 10 cm
3. III category III lesions where multiple and all are < 10 cm cross-sectional diameter
* Positive PCR or culture for confirmation of presence of mycobacterium ulcerans (MU).

Major

No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Participants with the following known or suspected medical conditions:

1. Any non BU related condition where participation in the study, as judged by the Investigator, could compromise the well-being of the participant or prevent, limit or confound protocol specified treatment and assessments.
2. History or current ascites, jaundice, myasthenia gravis, clinically significant renal dysfunction [estimated glomerular filtration rate (eGFR) < 50 mls/min], uncontrolled diabetes mellitus [glycated heaemoglobin (HbA1C )> 10%], and severe immune compromise (e.g., immunosuppressive drugs after organ transplant)
3. History of previous BU (except current infection)
* Planned/expected to require curative intent excision surgery, defined as excision of lesion which may include surrounding macroscopically healthy tissue with the aim of helping to sterilize the wound rather than improve wound healing alone, for their BU during the entire study period. Simple removal of necrotic slough and skin grafting is considered normal wound care and allowed.

Summary
Brief summary
The goal of this interventional clinical trial is to determine if treatment with 4 weeks of telacebac (T) will completely heal lesions in participants with Buruli ulcer (BU) by 52 weeks after treatment initiation, without relapse and/or surgery. Males and females age 18 and older will be included.

* Participants will attend visits every week during treatment (4 weeks)
* Thereafter they will be followed every 2 weeks until week 24 followed by visits as weeks 30, 40 and 52.
