Filter by:This study is aimed to compare the efficacy and safety of medications currently used in Brazil for treatment of visceral leishmaniasis. The investigators will compare the effects of meglumine antimoniate, two formulations of amphotericin B: deoxycholate and liposomal, and a combination of meglumine plus the liposomal amphotericin B formulation. The study is designed to demonstrate the difference in efficacy measured as cure rate at six months after treatment and the safety profile based on the adverse event rate observed with each intervention.
The objectives of the study are to evaluate the safety, pharmacokinetics (PK), and efficacy of open label treatment with WR 279,396 (Topical Paromomycin/Gentamicin Cream)in subjects with cutaneous leishmaniasis (CL).
This is a phase II/III open, comparative dose trial to find the lowest single dose of AmBisome for the treatment of primary, symptomatic visceral leishmaniasis(VL), in HIV negative patients. In this trial, the minimum effective dose will be determined in a sequential step, dose escalation design, which minimises the number of patients exposed to low, potentially inadequate doses and provides contemporaneous comparative data against the manufacturer's recommended dose schedule in this indication.
The adequate treatment of the American tegumentary leishmaniasis is crucial since the disease, differently from the caused by the Old World species, is painful and not self-healing and may lead to the disfiguring mucosal involvement. So far, pentavalent antimony compounds have been considered the treatment of choice for cutaneous leishmaniasis (CL), however, these drugs present high frequency of side effects and important disadvantages as parenteral administration and need for careful renal and cardiac monitoring. Azithromycin is a macrolide antibiotic, non-expensive, largely commercially available that has shown in-vitro and in vivo activity against different species of Leishmania. The main objective of this study is to evaluate the efficacy and safety of oral azithromycin for the treatment of CL. The efficacy of oral treatment of azithromycin 500 mg/day for 20 days is going to be compared with the standard treatment of intramuscular injections of 20 mg/Kg/day of pentavalent antimonials (Glucantime®) for 20 days in patients with CL from two endemic regions of Brazil: the metropolitan region of Belo Horizonte and Montes Claros (MG)in the southeast Brazil and in Corte de Pedras (Bahia), Northeastern Brazil. The patients follow up lasts for 12 months.
The primary objective of this protocol is to treat laboratory confirmed cutaneous leishmaniasis with WR 279,396 in military health care beneficiaries. In this study "cutaneous leishmaniasis" is defined as Old World Leishmaniasis if acquired in the Southwest Central Asia/Middle East.
Miltefosine will be administered to Brazilian patients with kala azar
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.
