Study summary

This study evaluates the effect of clean wound management and dressing on complex zoonotic cutaneous leishmaniasis caused by L. major in the MENA region (Algeria). The patients will participate in the wound dressing themselves. The objective is to determine the amount of patients that can avoid systemic chemotherapy with pentavalent antimony which is compulsory for patients with complex CL lesions. In Algeria, this requires expensive hospital care because of the eventual toxic side effects of Sb(V).

Read the detailed description

The investigator initiated, non-interventional LeiClean Trial with 100 CL patients presenting complex CL lesions, normally in need of a systemic an in-door treatment with meglumine antimoniate and in risk of systemic antimony toxicity (see inclusion criteria!) during the CL season of 2017/18 is part of the renewed cooperation treaty between the IPA and WM e. V. and originates from encouraging compassionate use observations after topical LeiClean treatment authorized by the Algerian Ministry of Health in December 2015. The study will be carried out in the ZCL region of M'Sila and Bou Saada.

The German Regulation Authority, BfArM, has granted a special approval according to §11 MPG (German regulation for Medical Devices) to the new filmogenic gel dressing LeiProtect®. The patients with complex cutaneous leishmaniasis (Giemsa and PCR confirmed) elected for indoor treatment with systemic antimony treatment are given the option for a LeiClean treatment of their lesions; they are instructed on hand hygiene and LeiProtect® dressing of their lesions which they carry out themselves at home during seven days. On day eight they come for lesion cleansing and photographic monitoring before they start another weekly LeiClean cycle. The patients can at any time opt for a conventional systemic chemotherapeutic treatment in a hospital if they are not satisfied with their healing progress. However, if the doctor realizes that after two months the hygienic wound management results in inadequate healing, he can also order hospital for the patients. The doctor will allow the patients to visualise their healing progress over the course of the trial through digital images on the computer.

After complete epithelisation of the lesions, the patients come for controls at monthly intervals up to a period of five months to check for eventual lesion relapses. The costs of the LeiClean outdoor treatment will be evaluated and compared to the already known hospital costs per patient for a three-week systemic indoor Sb(V) treatment.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 3, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
