Filter by:The primary objective is to determine clinical bioequivalence of Amphotericin B liposome for injection of Auromedics Pharma LLC, USA and AmBisome (Amphotericin B) liposome for injection of Astellas Pharma US, Inc., in patients with Visceral Leishmaniasis under fed condition
Bolivian cutaneous leishmaniasis due to Leishmania braziliensis was treated with the combination of miltefosine (150 mg/day for 28 days) plus intralesional pentamidine (120 ug/mm2 lesion area on days 1, 3, and 5).
New point-of-care (POC) tests are needed and assessing the performance of these tests for cutaneous leishmaniasis (CL) in Afghanistan may help increasing the number of CL patients with access to accurate diagnosis, and enable prompt treatment. Simpler tests could improve treatment access and benefit patients and communities, by reducing the risk of sequelae and the risk of disease transmission. CLeishPOCAFG aims to advance the diagnosis of CL by using more accurate and field-amenable methods.
The safety and effectiveness of AmBisome 15 mg/kg, given over 15 days in 5 biweekly infusions of 3 mg/kg on an outpatient basis, is evaluated in clinically diagnosed PKDL patients of 12 years and older in a highly endemic area in Bangladesh. This is a prospective study, with the objective to assess final cure 12 months after treatment.
Leishmaniasis is considered by the WHO as emerging and uncontrolled diseases. They are the second leading cause of death and the fourth leading cause of morbidity in tropical diseases. Leishmaniasis is parasitic reticulo-endotheliosis, the pathogenic agent of which is a flagellated protozoan belonging to the genus Leishmania. It is estimated that there are about 2 million new cases per year. Effective treatments against visceral leishmaniasis are few and resistance problems appear. To date, only a canine vaccine is available protecting dogs from the development of canine leishmaniasis to L. infantum. In man, in parallel clinical cases, leishmaniasis is characterized by a large number of asymptomatic carriers. This is the case in the Alpes-Maritimes where 50% of the inhabitants of the hinterland of Nice are carriers of the parasite. the investigators wish to study the protective immune response to the parasite and more particularly to the asymptomatic carriers. Indeed, these patients were infected with the parasite and did not develop the disease. Understanding the protective immune response in these patients against the parasite is therefore paramount in the development of a human leishmaniasis vaccine. For this purpose, the investigator wants to make an ex vivo study of the immune response of lymphocytes coming from asymptomatic carriers after stimulation by Leishmania vaccine peptides. It also wants to describe the immune response, after stimulation by these peptides, in the lymphocytes of subjects asymptomatic carriers and lymphocytes from subjects not infected with the parasite and comparing them. This study is unicentric and non-randomized. It wishes to recruit 20 asymptomatic carriers of L. Infantum and 10 uninfected subjects. They will be selected from our database. A simple blood sample will be taken. After verification by quantitative PCR and western blotting of their status towards leishmaniasis, the team will divide them into two groups (asymptomatic or healthy). Then the blood samples will be sent to the team of Jean Loup Lemesre of the Laboratory INTERTRYP - UMR177 of the IRD in Montpellier. ELISPOT analysis and assay of cytokines and proteases to describe the immune response of the two groups and to compare them. In addition, cell typing will be performed by flow cytometry to determine the type of lymphocytes involved in the immune response against Leishmania peptides. HLA typing will also be performed to validate the HLA coverage of the peptides tested. Finally, an analysis of the transcryptome will be carried out, which will allow to identify the differential expression of genes and metabolic pathways involved in the immune response and thus to understand how asymptomatic people can control the infection.
A clinical trial to asses efficacy and safety of Transition-state Analog Inhibitor of Human Purine Nucleoside Phosphorylase for topical use associated standard antimonial in the treatment of Cutaneous Leishmaniasis in Bahia, Brazil.
Visceral leishmaniasis (VL) also known as kala-azar is a public health problem in Bangladesh. Since 2005 a national kala-azar elimination program is going on in the country. The program has preparatory, attack, consolidation and maintenance phases. The target of the program is to reduce the VL incidence less than 1 per 10,000 people at upazila (sub-district) level in VL endemic upazilas of the country. The program is heading successfully to its consolidation phase. During attack phase house to house search for VL suspects and also suspects with Post-kala-azar Dermal Leishmaniasis (PKDL) was the tool for early diagnosis of VL and PKDL cases. Indoor residual spraying with insecticide (Deltamethrin) was the method for sand fly control to reduce the transmission of the disease. Since in the consolidation phase the VL case load is many times less than that in the attack phase, house to house search for VL and PKDL cases and IRS for vector control is no more cost-effective for the program. Therefore there is a need for alternative methods for active search of VL and PKDL cases and method for sand fly control, appropriate for the consolidation phase. In the present study the investigators propose to investigate the efficacy of Inesfly 5AIGRNG TM containing Alphacypermethrin 0.7%; D-Allethin 1.0% and Pyriproxyphen (0.063%), commercial available durable wall lining (DWL), impregnated of existing bed-net with insecticide tablet, KO TAB 123, indoor residual spraying (IRS) with Delthamethrin against a control group Methods: A cluster randomized controlled design to measure sand fly density reduction at intervention household as well as sand fly mortality by entomological methods. Outcome measures/variables: reduction of sand fly density at intervention household and sand fly corrected mortality on intervention surfaces compare to control households/conditions.
This is an open label, Phase III, randomized, controlled, parallel arm multicentre non-inferiority clinical trial to compare the efficacy and safety of two combination regimens of Miltefosine and Paromomycin with the standard SSG-PM for the treatment of primary adult and children VL patients in Eastern Africa.
This protocol will compare topical paromomycin to standard intralesional (IL) antimony (Sb) to placebo for L braziliensis in Bolivia.
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.
