Filter by:The objective of this study is to determine the effectiveness and toxicity of WR 279,396, a topical cream for the treatment of cutaneous leishmaniasis. This study is to be conducted with a placebo control under double-blind conditions in a local population group in Tunisia where leishmaniasis is endemic.
The efficacy of LtSTA as a skin test antigen depends upon the sensitivity and specificity of the product. This study has been designed to measure the skin test responses to 15, 30, or 50µg doses of LtSTA. The measurements of non-specific reactivity due to components of the antigen solution and the product's ability to sensitize lymphocytes of Leishmania naïve persons when administered intradermally. The presence or absence of a local inflammatory response to the first skin test with each of three doses of LtSTA will provide insight on the specificity of the antigen in a naïve population. The local inflammatory response to LtSTA following the first and second repeat skin tests will indicate if the antigen is sensitizing after intradermal administration.
This study will test the ability of the topical cream WR 279,396 to treat the skin lesions caused by the parasite called leishmania. WR 279,396 is an antibiotic preparation that contains paromomycin + gentamicin. This cream will be compared to the effect of a topical cream containing paromomycin alone and to a placebo cream that contains no antibiotics. Therefore, this study will have three groups of patients, and they will be assigned to one of these treatments randomly. The study will be carried out without the patient or the physician knowing which cream is being used for which patient. The goal is to determine if WR 279,396 cream or the paromomycin cream is better than placebo, and if WR 279,396 is better than paromomycin alone.
Primary Objectives: Assess whether CL (caused by Leishmaniasis major) lesions treated with WR279396 improved the cosmetic outcome compared with no treatment (natural healing)
Cutaneous leishmaniasis (CL) is a worldwide disease, endemic in 88 countries, that has shown an increasing incidence the last two decades. It is estimated that in 2005, about of 20,000 new cases of CL were diagnosed in Colombia. So far, pentavalent antimony compounds have been considered the treatment of choice with a percentage of cure of about 85%. However, the high efficacy of these drugs is counteracted by their adverse events and disadvantages. Previous studies have shown that miltefosine could be a potential alternative of treatment for CL. The main objective of this study is to evaluate the efficacy and safety of miltefosine or thermotherapy for the treatment for CL. In this study the efficacy of oral treatment of miltefosine 150 mg/day for 28 days or a thermotherapy device used for one session at 50 celsius degrees during 30 seconds will be compared with the standard treatment of intramuscular injections of 20 mg/Kg/day of pentavalent antimonials (GlucantimeÒ) for 20 days in CL parasitologically proven patients. This trial will be conducted according to the International approved GCP (Good Clinical Practice) guidelines.
Cutaneous leishmaniasis is a parasitic skin lesion caused by different species of Leishmania and transmitted by the bite of infected sand flies. Leishmaniasis is exist in 88 countries, pentavalent antimonials (sodium stibogluconate and meglumine antimoniate) have been used as a standard treatment for this disease for last 80 years. Pentavalent antimonials are only available as injectable, which is painful, toxic, not affordable and moreover is not always effective even sometimes with several courses of treatment. Many different modalities are used to treat the disease with little success. Miltefosine is drug and has recently been shown to be effective in the treatment cutaneous leishmaniasis in Colombia. The molecular mechanisms that contribute to this effectiveness are not clearly understood. Only a well designed, randomized clinical trial can precisely evaluate the efficacy of any therapeutic modalities in cutaneous leishmaniasis. In this study the efficacy of oral treatment of miltefosine 2.5 mg per Kg body weight for 4 weeks will be compared with standard treatment of intramuscular injections of 60 mg/kg/day glucantime for 2 weeks in ACL parasitologically proven patients. At 8 weeks after the initiation of the treatment any patient in the group who received miltefosine and has not responded to the treatment will be treated with the standard intramuscular injections of 60 mg/kg/day glucantime for 2 weeks. The clinical trial will be carried out according to the International approved GCP (Good Clinical Practice) guide lines.
This study will examine why some people who become infected with the leishmaniasis parasite develop skin lesions and others do not. The parasite that causes leishmaniasis is transmitted by the bite of a sandfly. It can cause skin lesions that may persist for several months, spread to other parts of the body, and become infected with bacteria. Treated with medicine, leishmaniasis can be cured completely. People 1 year of age and older who live in the Mali villages of Kemena or Sougoula may be eligible for this study. Participants are injected with a small amount of inactive parasites into the skin of their arm. People who have a reaction to the test, and thus have been exposed to the parasite, are examined for skin lesions. Their lesions, if any, are evaluated and treated, and their participation in the study ends. Participants who do not react to the skin test are examined for skin lesions every month for 5 months. Those who are 18 years of age or older and have mild leishmaniasis skin lesions may have a small amount of fluid injected into a lesion in order to remove parasites for laboratory analysis. Patients' lesions may be photographed to compare what they look like before and after treatment. Lesions are treated with an ointment containing an antibiotic and a disinfectant twice a day for 20 days. The lesions are examined 1 and 3 weeks after treatment is completed to see if the disease has been cured. A few months later, the skin test is repeated to determine whether the person has been exposed to parasites over the past year. A blood sample may be drawn from some participants, depending on whether they have a reaction to the second skin test and whether they have developed skin lesions. The sample is drawn only from patients 18-65 years of age. Some blood drawn for the study may be used for genetic tests.
The purpose of this study is to determine whether low-dose pentavalent antimony is equally effective when compared to the standard-dose regimen in patients with cutaneous leishmaniasis. The study will be done in a field clinic in the state of Bahia, Brazil.
This study will test whether addition of imiquimod to standard antimony therapy provides a significant benefit in subjects with newly diagnosed cutaneous leishmaniasis. Based on our previous results, we hypothesize that lesions in patients who receive the combined treatment of pentavalent antimony and imiquimod as a first line therapy will resolve more rapidly and produce less scarring than treatment with pentavalent antimony alone.
Cutaneous leishmaniasis is typically treated with the parenteral product pentavalent antimony. Miltefosine is an oral agent shown to be active for mucosal leishmaniasis due to L braziliensis in Bolivia and cutaneous leishmaniasis due to L panamensis in Colombia. This trial is intended to evaluate miltefosine for cutaneous leishmaniasis due to L braziliensis in Bolivia. Patients will be randomly assigned to miltefosine or pentavalent antimony. Standard dose regimens will be used for both drugs.
