A Clinical Trial to Investigate Efficacy, Safety and Pharmacokinetics (PK) of Two LXE408 Oral Regimens and Oral Miltefosine as Active Control in Participants Aged ≥ 18 Years Old With Localized Cutaneous Leishmaniasis in the Region of the Americas (AMR).
250 patients around the world
Available in Brazil, Panama
Participants who met all inclusion criteria and none of the exclusion criteria will be
randomized to the study will be allocated to one of three arms in a 2:2:1 ratio.
- Arm 1: LXE408 BID for 14 days followed by placebo BID for 14 days
- Arm 2: LXE408 BID for 28 days
- Arm 3: Miltefosine 50 mg PO TID for 28 days orally
Each arm will consist of a screening period of up to 15 days, a 28-day treatment period,
and a follow-up period from Day 29 to Day 180. During the treatment period, all
participants will return to the sites at Days 1, 8, 15, 22 and 29 (+/- 2 days). During
the follow-up period they will return for the Day 63 (+/- 7 days), Day 90 (+/- 7 days)
and Day 180 (+/- 14 days) visits. If at D90 participants present a re-epithelization of
the ulcer(s) more or equal to 75% but less than 100%, they will be asked to return at
D105 for a late responder assessment.
