Primary Outcome Measures:
- Final Clinical Cure for Index Lesions [ Time Frame: Initial clinical cure by day 63 and no relapse by day 168 ]
Final clinical cure was defined as follows:
- Subject has initial clinical cure (100% re-epithelialization of index lesion by nominal Day 63); OR,
- Subject has initial clinical improvement (> 50% re-epithelialization of index lesion by nominal Day 63 followed by 100% re-epithelialization of the index lesion on or before nominal Day 100; AND,
- Subject has no relapse of index lesion by Day 168. Relapse was defined as an index lesion meeting the criteria for initial clinical cure that had any new ulceration/nodule (> 0 x 0 mm measurement) by nominal day 168, or an index lesion meeting the criteria for initial clinical improvement that subsequently enlarged by nominal Day 168.
Secondary Outcome Measures:
- Detectable Paromomycin Plasma Levels [ Time Frame: Day 4, 7, 12, 17, 20, 28 ]Paromomycin plasma concentrations following administration of paromomycin alone or WR 279,396 in adults
- Paromomycin Plasma Concentrations in Children [ Time Frame: 0 and 4 hours on days 1 and 20 ]Paromomycin plasma concentrations 4 hours following administration of paromomycin alone or WR 279,396 in children
- Pharmacokinetic Parameter: Cmax [ Time Frame: 0, 0.5, 1.0, 2.0, 3.0, 4.0, 8.0, 12.0, 24.0 hours on both Days 1 and 20 ]Cmax of paromomycin following administration of paromomycin alone or WR 279,396 to adults in Panama
- Pharmacokinetic Parameter: Tmax [ Time Frame: 0, 0.5, 1.0, 2.0, 3.0, 4.0, 8.0, 12.0, 24.0 hours on both Days 1 and 20 ]Pharmacokinetic Parameter: Tmax
- Pharmacokinetic Parameter: Area Under the Curve (AUC) [ Time Frame: 0, 0.5, 1.0, 2.0, 3.0, 4.0, 8.0, 12.0, 24.0 hours on both Days 1 and 20 ]Area under the curve (AUC) of paromomycin following administration of paromomycin alone or WR 279,396 to adults in Panama
- Pharmacokinetic Parameter: t(1/2) [ Time Frame: 0, 0.5, 1.0, 2.0, 3.0, 4.0, 8.0, 12.0, 24.0 hours on both Days 1 and 20 ]t(1/2) of paromomycin following administration of paromomycin alone or WR 279,396 to adults in Panama
- Pharmacokinetic Parameter: Cmax/D [ Time Frame: 0, 0.5, 1.0, 2.0, 3.0, 4.0, 8.0, 12.0, 24.0 hours on both Days 1 and 20 ]Maximum observed plasma concentration divide by topical dose (Cmax/D) of paromomycin following administration of paromomycin alone or WR 279,396 to adults in Panama
- Pharmacokinetic Parameter: AUC/D [ Time Frame: Days 1 and 20 ]Area under the plasma concentration-time curve over 24 hrs divided by topical dose (AUC/D) of paromomycin following administration of paromomycin alone or WR 279,396 to adults in Panama
- Final Clinical Cure on All Lesions Independent of Subjects [ Time Frame: Initial clinical cure by day 63 and no relapse by day 168 ]
Final clinical cure was defined as follows:
- Subject has initial clinical cure (100% re-epithelialization of lesion by nominal Day 63); OR,
- Subject has initial clinical improvement (> 50% re-epithelialization of lesion by nominal Day 63 followed by 100% re-epithelialization of the lesion on or before nominal Day 100; AND,
- Subject has no relapse of lesion by Day 168. Relapse was defined as a lesion meeting the criteria for initial clinical cure that had any new ulceration/nodule (> 0 x 0 mm measurement) by nominal day 168, or a lesion meeting the criteria for initial clinical improvement that subsequently enlarged by nominal Day 168.
- Number of Index Lesions Meeting Criteria for Clinical Cure During the Study [ Time Frame: Day 1, 4, 7, 12, 17, 20, 28, 35, 42, 49, 56, 63, 100, 168 ]Number of study participants who meet the criteria for clinical cure (100% re-epithelialization) at specified timepoints during the study.

- Is the subject or legal guardian able to give written informed consent or assent, as appropriate?
- Does the subject have a diagnosis of CL in at least one lesion by at least one of the following methods: 1) positive culture for promastigotes, or 2) microscopic identification of amastigotes in stained lesion tissue.
