About this study
Official title: The Clinical Effect of Intralesional Injection of Levofloxacin for the Management of Cutaneous Leishmaniasis: Single Arm Open-label Trial
Aim of the study to evaluate the effectiveness of intralesional levofloxacin 0.5% solution as a local injection in treating cutaneous leishmaniasis.
In an open-label single-arm clinical trial, all patients were given intralesional levofloxacin injections; the patients had cutaneous leishmaniasis lesions. Each lesion was considered a case in the final analysis. Each lesion will be followed up for 90 days (censor endpoint) or until the lesions are cured.
Intralesional levofloxacin (5 mg/ml, 100 ml, Tavanic®, Sanofi, France) will be injected into each lesion based on its size (5 mg/cm2). The infiltration of intralesional dose will be given once weekly for up to 6 weeks. Treatment will be stopped in patients cured before 6 weeks of treatment. A fine insulin needle will be used to infiltrate the lesion.
Read the detailed description
Local therapies have been recommended by the World Health Organization (WHO), the Pan American Health Organization, and other experts as an alternative to systemic drugs in patients with at least four lesions smaller than 4 cm in diameter, especially when the face or joints are not affected. Usually, they are easy to use and have a lower risk, toxicity, and cost compared to traditional therapies. Local treatment includes thermotherapy, cryotherapy, and topical and intralesional drugs. The last approach is effective and safe in localized forms

Levofloxacin 0.5%Drug
Also called Tavanic
Intralesional levofloxacin (5 mg/ml, 100 ml, Tavanic®, Sanofi, France) will be injected into each lesion based on its size (5 mg/cm2). The infiltration of intralesional dose will be given once weekly for up to 6 weeks. Treatment will be stopped in patients cured before 6 weeks of treatment, and patients were only asked to come for lesion assessment. A fine insulin needle will be used to infiltrate the lesion.
The lesion will be thoroughly infiltrated with the drug solution until the base will be completely blanched. Depending on the lesion size, the amount of solution required ranged from 0.2 to 4.0 ml per lesion. No local anesthesia was added. The solutions were injected intralesionally and not subcutaneously.

What is being measured
The primary outcome is the main question the study is designed to answer.
Cure rate
Patients were followed weekly up to 90 days after the first injection; four parameters were used for assessment as follows according to Sharquie modified leishmania score: 1. Measure the size of the lesion through the surface area 2. Measurement of the induration of the lesion 3. Assess the degree of erythema of the lesion 4. Assess the presence and absence of ulceration The obtained data is converted from numbers into scores. The total score was calculated by adding individual scores. Score 13-16: Mild response. Score 9-12: Moderate response. Score 5-8: Marked response. Score 0-4: Complete response \& clearance Both marked and complete responses are considered as a cure
Measured: From enrollment to the end of treatment up to 90 days.

Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 30 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

What does the primary outcome measure?
Cure rate (time frame: From enrollment to the end of treatment up to 90 days.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Sep 2025; AzTrials last refreshed its copy on 8 Nov 2026.
