Active clinical trials for "Leishmaniasis, Visceral"

The purpose of this study is to determine if amphotericin B is effective against visceral leishmaniasis in Brazilian children. Amphotericin B will be compared to meglumine antimoniate which is the current approved drug used for this disease in Brazil.

The overall objective of this trial is to identify a safe and effective combination, (coadministration) short course treatment for the treatment of visceral leishmaniasis which could be easily deployed in a control programme and will reduce the risk of parasite resistance occurring. Safety and tolerability should be such that the combination can be easily deployed.

This modular Program will first confirm the safety and efficacy of Paromomycin IM Injection when given to an expanded population in the outpatient setting in experienced VL centers and subsequently evaluate the effectiveness of an expanded access model of providing Paromomycin IM Injection to progressively more resource-constrained clinics in Bihar, India.

The purpose of this study is: To evaluate the Safety and Efficacy of four different short-course regimens of Amphotericin B emulsion in treatment of Kala-azar (visceral leishmaniasis) subjects who are either treatment naive or treatment resistant to other antileishmanial drugs except amphotericin B containing preparations. To assess the safety and efficacy of single-bolus infusion of Amphotericin B emulsion in treatment of Kala-azar.

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.

Sitamaquine is an 8-aminoquinoline which is being developed as an oral treatment for visceral leishmaniasis (VL). Pre-clinical and subsequent clinical investigations have demonstrated oral efficacy against Leishmania donovani. The purposes of this study are to characterise the pharmacokinetic profile of sitamaquine, administered orally, and to determine if the pharmacokinetic profile is affected by administration with food. The study is also designed to further characterise the safety and tolerability of sitamaquine compared with amphotericin B, particularly in reference to renal, hepatic and cardiac adverse events, prior to initiation of phase III studies. Finally the study will investigate the efficacy of a 21 day treatment course. Previous studies have used 28 days dosing, but parasitological evidence from one study suggests that shorter courses may be effective.

The investigators are using a sequential design to combine miltefosine and AmBisome in different doses.

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

We hypothesize that PKDL develop after SSG as well as after Miltefosine mono-therapy for VL; anti-inflammatory cytokines such as IL-10, TGF-β, serum lipids play key role for its pathogenesis & PKDL patients are genetically predisposed; diagnostic tool based on immunofluorescence technique will be more sensitive than slit skin examination for diagnosis of PKDL.

Kala azar (KA) or visceral leishmaniasis (VL) is endemic in several districts of Bangladesh with the highest incidence in Mymensingh, Pabna and Tangail districts. ICDDR,B is involved in a project for improving the surveillance of KA in Trishal, Mymensingh since 2005. Improvement of case detection is necessary for both surveillance purposes and better control. The aims of this pilot study are to assess some newer techniques for diagnosis of KA using blood and urine samples of suspected cases; and evaluate response to treatment with sodium stibogluconate to which resistance has been reported in India, considered to be a part of the same zone harboring the disease agent Leishmania donovani and transmitted by the same vector Phlebotomas argentipes (sand-fly). No data is currently available on response to sodium stibogluconate in KA patients in Bangladesh. Although a number of new drugs have been evaluated in the treatment of KA in India and Kenya, no trial has so far been conducted in Bangladesh. A team of researchers from GlaxoSmithKline (UK) had recently visited Bangladesh to evaluate if it would be possible to conduct a Phase-III clinical trial with sitamaquine. They interacted with scientists of ICDDR,B and expressed their interest to help develop ICDDR,B's capacity in order to include Bangladesh as one of the sites for the planned, multi-centre, Phase-III trial of sitamaquine; India and Nepal are two other possible sites for the trial. The aims of the proposed study are to train physicians and laboratory personnel in preparation for the future drug trial(s) on KA as well as to compare different tests for its diagnosis that might improve case detection at the field level and used for research purposes. The investigators will also examine in greater detail the different Leishmania species circulating in the area of Mymensingh and whether treatment failure and occurrence of Post Kala azar Dermal Leishmaniasis (PKDL) is associated with certain species.
