About this study

Official title: A Multi-Arm, Multi-Stage Randomized Controlled Clinical Trial Evaluating Systemic Therapeutic Regimens for the Treatment of Cutaneous Leishmaniasis in Ethiopia

MAMS4CL comprises a clinical trial with three embedded sub-studies designed to comprehensively evaluate the administered treatments and assess the impact of CL treatment on patients and the healthcare system.

The multi-centre multi-arm multi-stage phase 3 clinical trial is designed to rigorously evaluate a total of 4 alternative treatment options for systemic CL against Sodium Stibugluconate (SSG) as the standard of care. The trial comprises two seamlessly linked stages. In stage 1, all four investigational arms will be evaluated against the control arm for efficacy to inform the selection of the arms, based on a pre-defined efficacy threshold that will advance to stage 2, in addition to the control arm. After stage 2, the experimental interventions will be compared with SSG similar to a standard superiority trial for efficacy. The general study design in stage 1 and stage 2 will be identical; only the number of investigational arms may differ.

Patients will be randomized into the respective treatment arms at the recruitment sites of Arba Minch hospital, Boru Meda hospital and ALERT hospital in Ethiopia. Individuals will be hospitalized during the entire course of their treatment. As different arms have different treatment duration, patient hospitalization period and visit schedules will differ between arms. In total, the study will last 180 days for each participant.

Being tested
Sodium Stibogluconate (SSG), Miltefosine, Miltefosine + Paromomycin, Liposomal Amphotericin B (LAmB), Pentamidine isethionate

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. For each of the investigational arms (miltefosine/miltefosine + paromomycin / liposomal amphotericin B/pentamidine isethionate), to determine whether it has superior efficacy to the control arm in terms of achieving cure of all lesions at Day 90

    Cure of all lesions at Day 90, pairwise compared between the control arm and each of the investigational arms.

    Cure at the lesion level is defined as 100% improvement of the area of erythema, induration, and ulceration of a lesion compared to the baseline assessment. Cure at the patient level is defined as cure of all lesions present at baseline, and no new lesions appearing. Cure is assessed at multiple timepoints, including Day 90.

    Cure at Day 90 is defined as cure assessed at Day 90, or cure assessed at the latest available time point before Day 90, without relapse (known as last observation carried forward (LOCF)).

    Measured: Day 90

Secondary outcomes (6)
  1. For each investigational arm, to determine whether it has superior efficacy to the control arm, in terms of achieving cure of all lesions at Day 180.

    Cure of all lesions at Day 180, pairwise compared between the control arm and each of the investigational arms .

    Cure at Day 180 is defined as cure assessed at Day 180, or cure assessed at the latest available timepoint before Day 180, without relapse (LOCF).

    Measured: Day 180

  2. To compare between the control arm and each of the investigational arms: proportion of participants with all lesions cured, cure for all lesions considered individually, the proportion of participants whose index lesion is cured.

    Cure at End of Treatment, Day 42, Day 90, and Day 180 at the patient and lesion level.

    1. Cure of all lesions (patient level) at EoT and D42, pairwise compared between each of the investigational arms and the control arm.
    2. Cure at End of Treatment, Day 42, Day 90, and Day 180, at the lesion level, adjusted for patient level, pairwise compared between each of the investigational arms and the control arm.
    3. Cure of the index lesion at End of Treatment, Day 42, Day 90, and Day 180, pairwise compared between each of the investigational arms and the control arm.

    Measured: End of Treatment, Day 42, Day 90 and Day 180

  3. To compare between the control arm and each of the investigational arms: proportion of participants that reach at least substantial improvement of all lesions and the index lesion + at least substantial improvement for all lesions individually,

    Substantial improvement at participants and lesion level at End of Treatment, Day 42, Day 90, and Day 180 is defined as ≥50%-99% improvement of the area of erythema, induration, and ulceration, compared to the baseline assessment.

    Substantial improvement at a specific timepoint is defined as substantial improvement assessed at that timepoint, or at the latest available earlier timepoint.

    At least substantial improvement is defined as substantial improvement or cure.

    1. At least substantial improvement of all lesions (patient level) at EoT, D42, D90, and D180, pairwise compared between each of the investigational arms and the control arm.
    2. At least substantial improvement at EoT, D42, D90, and D180 at the lesion level, adjusted for patient level, pairwise compared between each of the investigational arms and the control arm.
    3. At least substantial improvement of the index lesion at EoT, D42, D90, and D180, pairwise compared between each of the investigational arms and control arm.

    Measured: End of Treatment, Day 42, Day 90, Day 180

  4. To compare between the control arm and each of the investigational arms, the proportion of participants with treatment failure at Day 42, Day 90, and Day 180.

    Treatment failure at Day 42, Day 90, and Day 180. Treatment failure is defined as having the study treatment suspended for any reason as described in section 4.7.2, as having no improvement compared to baseline at Day 42, as having <50% improvement compared to baseline at Day 90, as having anything but all lesions cured at Day 180, or as having worsening of lesions or new lesions compared to the previous visit.

    Measured: Day 42, Day 90, Day 180

  5. To assess safety by describing safety & tolerability of each arm by listing number, proportion & severity of AEs/Comparing number, proportion & reason of withdrawals and number & proportion of patients with SAEs between control and investigational arm

    Assessment of safety by:

    1. Number and proportion, type, and severity of adverse events (both all and possibly, probably or definitely related to the study intervention) reported per study arm during the course of the study,.
    2. Permanent withdrawal from study intervention due to an adverse event that is possibly, probably or definitely related to the study intervention, including reason for withdrawal;
    3. Having at least one SAE that is possibly, probably or definitely related to the study intervention, between administration of the first dose of study medication and Day 180.

    Measured: Day 180

  6. To compare between control arm and each investigational arm, the change in patient-reported outcomes over time between treatment arms

    Assessment of patient-reported outcomes by:

    1. Dermatology Life Quality Index (DLQI) and Children's DLQI (cDLQI): measured at Day 1, Day 42, Day 90, and Day 180 as a discrete number that can be categorized. Change in patient reported outcome will be measured as the difference in score between the subsequent visits (Day 42, Day 90, and Day 180) and Day 1, and compared between arms.
    2. Cutaneous Leishmaniasis Impact Questionnaire : measured at Day 1, Day 42, Day 90, and Day 180 as a discrete number. Change in patient reported outcome will be measured as the difference in score between the subsequent visits (Day 90, Day 180) and Day 1, and compared between arms.
    3. Patient and Observer Scar Assessment Score measured at Day 42, Day 90, and Day 180 as a discrete number. Scores for each time point will be compared between arms.

    Measured: Day 1, Day 42, Day 90, Day 180

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 12 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: opening soon, as of the sponsor's last update on 10 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Ethiopia. Whether a site is taking part right now should be confirmed with that site. See every site.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Bart Smekens (+3233455672, bsmekens@itg.be), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

For each of the investigational arms (miltefosine/miltefosine + paromomycin / liposomal amphotericin B/pentamidine isethionate), to determine whether it has superior efficacy to the control arm in terms of achieving cure of all lesions at Day 90 (time frame: Day 90). 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 10 Mar 2026.
