Miltefosine and GM-CSF in Cutaneous Leishmaniasis

April 3, 2020 updated by: Paulo Roberto Lima Machado, Hospital Universitário Professor Edgard Santos

Miltefosine and GM-CSF in Cutaneous Leishmaniasis: a Randomized and Controlled Trial

Cutaneous leishmaniasis (CL) standard treatment is done with parenteral pentavalent antimony (Sbv) at the dose of 15-20mg / kg per day for 20 days. However, therapeutic failure has been described in up to 50% of patients, and the long period of 60 to 90 days required for healing of the ulcerated lesion indicate the need for alternative drugs. Currently the alternatives include other parenteral drugs such as pentamidine and amphotericin B, whose use is limited either by toxicity or because, as with Sbv, the parenteral route hinders adherence and regularity of treatment in the rural area. Recent studies by our group indicate that oral miltefosine is the most effective drug for the treatment of patients with CL caused by L. (V.) guyanensis and L. (V.) braziliensis in Brazil, with a cure rate of 71.4% and 75% respectively. CL pathogenesis is associated with intense inflammatory infiltrate and tissue damage. Previous trials associating GM-CSF to Sbv improved the cure rate of CL caused by L. (V.) braziliensis. The objective of this trial is to evaluate the therapeutic response to the use of miltefosine associated to GM-CSF in the treatment of CL caused by L. (V.) braziliensis in an endemic region in Bahia and Ceará, and by L. (V.) guyanensis in the Amazon region.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Final cure rate or complete cicatrization of the ulcer
Time Frame: 6 months after the end of treatment
All lesions will be categorized as either active or healed (cured) at follow-up visits. Only lesions with complete re-epithelialization, without raised borders, infiltrations or crusts will be considered healed. Evaluation of the lesions will be performed by 2 clinicians who will be unaware of the group assignment of all patients. Bidirectional measurements of ulcers will be taken of the patients' lesions at the initial visit, and at each follow-up visit with standardized caliper. The area involved will be calculated as the product of the two measurements.
6 months after the end of treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
