Filter by: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.
Cutaneous leishmaniasis is a worldwide disease, endemic in 88 countries, that has shown an increasing incidence over the last two decades. 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 many disadvantages and adverse events. Previous studies have shown nitric oxide to be a potential alternative treatment when administered topically with no serious adverse events. However, due to the unstable nitric oxide release, the topical donors needed to be applied frequently, making the adherence to the treatment difficult. The electrospinning technique has allowed the production of a multilayer transdermal patch that produces a continuous and stable nitric oxide release. The main objective of this study is to evaluate this novel nitric oxide topical donor for the treatment of cutaneous leishmaniasis. A double-blind, randomized, double-masked, placebo-controlled clinical trial, including 620 patients from endemic areas for leishmaniasis in Colombia was designed to investigate whether this patch is as effective as meglumine antimoniate for the treatment of cutaneous leishmaniasis but with less adverse events. Subjects with ulcers characteristic of cutaneous leishmaniasis will be medically evaluated and laboratory tests and parasitological confirmation performed. After checking the inclusion/exclusion criteria, the patients will be randomly assigned to one of two groups. During 20 days Group 1 will receive simultaneously meglumine antimoniate and placebo of nitric oxide patches while Group 2 will receive placebo of meglumine antimoniate and active nitric oxide patches. During the treatment visits, the medications will be administered daily and the presence of adverse events assessed. During the follow-up, the research group will visit the patients at days 21, 45, 90 and 180. The healing process of the ulcer, the health of the participants, recidivisms and/or reinfection will also be assessed. The evolution of the ulcers will be photographically registered. In the case that the effectiveness of the patches is demonstrated, a novel and safe therapeutic alternative for one of the most important public health problems in many countries will be available to patients.
This study is being conducted to assess the safety and efficacy of amphotericin B deoxycholate in doses of 0.75 mg/kg or 1.0 mg/kg for 15 doses. In each arm the drug is given in the conventional way every alternate day against the daily administration regimen being tested.
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.
The purpose of this study is to assess the efficacy and safety of SSG 30 days alone, PM 21 days alone and SSG and PM as a combination course of 17 days in the treatment of patients with VL.
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.
Symptomatic Visceral Leishmaniasis(VL)is fatal; Due to the increasing resistance to standard therapy with antimonials, there is a need for new safe, efficacious, low-cost therapies for the treatment of VL. Paromomycin is an off-patent aminoglycoside antibiotic with anti-leishmaniasis activity. This study will test the safety and efficacy of paromomycin in the treatment of patients with VL in India.
This study will evaluate the safety and immunogenicity of the Leish-111f + MPL-SE vaccine in adult subjects who have no evidence of previous exposure to the Leishmania parasite.
This study will evaluate the safety of the Leish-111f + MPL-SE vaccine in adult subjects with a previous exposure to the Leishmania parasite (but without current or past history of leishmaniasis).
This study will evaluate the safety of the Leish-111f + MPL-SE vaccine in adult patients with cutaneous leishmaniasis.
