Filter by:Cutaneous leishmaniasis (CL) is endemic in Israel and is caused by Leishmania major or Leishmania tropica. CL is usually a benign disease and limited to the skin. One of the local treatment available is intralesional (IL) Pentostam injection. During the current study the investigators will monitor the adverse effects of this treatment and will follow up the recovery of the lesions after Pentostam injections.
The objectives of the study are to evaluate the safety and efficacy of open label treatment with WR 279,396 (topical paromomycin & gentamicin) in patients with non-complicated, non-severe cutaneous leishmaniasis (CL).
The purpose of this study is to evaluate the therapeutic response to fluconazole in patients with cutaneous leishmaniasis caused by and L.(V.)guyanensis and L.(V.) braziliensis.
This study is a single-site trial assessing the specificity of CL Detect™ Rapid Test versus the gold standard for Leishmania diagnosis in the US which is microscopic identification of Leishmania amastigotes in a stained lesion sample. Subjects will be patients who present for dermatology consultation with a primarily ulcerated lesion. After informed consent is obtained and the subject is screened for eligibility, 2 diagnostic samples will be collected from the subject's lesion in the following order: 1) one sample will be obtained with a dental broach for use with the CL Detect™ Rapid Test and 2) a second sample will be obtained by scraping for use in the microscopic identification of amastigotes. Samples will be analyzed by microscopy and CL Detect™ Rapid Test. The CL Detect™ Rapid Test will be performed by different operators who are clinical staff members. These staff members, blinded to each other's results, will evaluate the samples from each method independently. Each of the 150 study subjects will be followed administratively to the point where a diagnosis is established (if possible) for their tested lesion, even if that diagnosis is not cutaneous leishmaniasis (CL). If a specific diagnosis cannot be determined for a non-CL lesion, the investigator will assign a "likely etiology" (eg, infectious, oncological, immunological, vascular, or "undetermined/other" origin). Based on the diagnosis determined for each lesion, subjects will be referred for appropriate treatment.
The proposed study encompasses a two-step approach. The first aiming to determine the safety of Topical 3% Amphotericin B Cream when applied three or two times per day for 4 weeks in subjects with un-complicated Cutaneous leishmaniasis (CL) whilst the second focusing in having and indication of the efficacy of the two above mentioned regimens of Topical 3% Amphotericin B Cream For the first step, 30 subjects will be randomly assigned to receive direct observed treatment (DOT) with Topical 3% Amphotericin B Cream applied either three or two times per day for 4 weeks. Enrolment will be temporarily halted until all 30 subjects (15 in each group) have been enrolled and completed the 28 day treatment course. An interim analysis of all safety (Adverse Events, including local reactions and lab parameters) and pharmacokinetics collected on subjects who were randomized will be performed by data safety monitoring board. If no serious adverse events (SAEs) related to the study drug are identified on the first 30 subjects by the end of the treatment course, 50 additional subjects will be randomly allocated to receive Topical 3% Amphotericin B Cream either three or two times per day for 28 days Subjects will have a follow-up visit at the end of therapy, on Day 45± 5 days, Day 63± 5 days and on Days 90± 14 days and on Day 180, minus 14d, plus 4 weeks to assess efficacy, as measured by the number of subjects who fulfil the cure criteria: 100% re-epithelialization of the lesion(s) by Day 90 and no relapse by Day 180. All subjects will be followed up to Day 180 for final analysis of efficacy.
This study is a pivotal Phase 3, randomized, double-blind, 3-site, two-group trial assessing the efficacy and safety of WR 279,396 Topical Cream and Paromomycin Alone Topical Cream in subjects with CL in Panama. The primary objective of this study is to determine if WR 279,396 results in statistically superior final clinical cure rates of an index lesion when compared with Paromomycin Alone for the treatment of CL in Panama expected to be caused by L panamensis.
The purpose of the study is to evaluate the sensitivity and specificity of CL Detect, in subjects with suspected CL in Tunisia.
Infections caused by the protozoan parasite Leishmania include cutaneous (CL), mucosal (ML) and visceral leishmaniasis (VL). Over 12 million people currently suffer from leishmaniasis, and approximately 2 million new cases occur annually, making it a major global health problem. CL CL caused by Leishmania tropica is endemic around the city of Bikaner in Thar Desert region of the State of Rajasthan . WHO recommends antimonials such as sodium stibogluconate (SSG) to treat CL. However, these drugs are toxic and have poor patient compliance as they require multiple intramuscular or intralesional injections for 3 weeks. In addition, the emergence of drug-resistant strains is rapidly increasing worldwide. We are interested in novel treatments for CL that are safe, easy to administer and effective in inducing long-term cure. Recently, radio-frequency-induced heat (RFH) therapy has been used to treat CL. This treatment involves the controlled and localized delivery of radiofrequencies into lesions for 30-60 seconds under local anesthesia. Several short-term follow-up (4-5 months) studies as well as one long-term follow-up (12 months) study involving US soldiers who were infected with L. major in Iraq found that RFH therapy was comparable, or even better, than systemic antimonials. However, more studies are needed to establish long-term efficacy of RFH therapy in treatment of CL caused by other Leishmania species that are difficult to treat with conventional drugs, and to determine the risk of disease recurrence if any in patients living in Leishmania endemic regions. The goal of this trial is to compare long term efficacy of RFH therapy in treatment of CL caused by L. tropica in patients residing in Leishmania-endemic regions of India.
This is an expanded access treatment protocol designed to provide a topical cream treatment option to military health care beneficiaries with parasitologically confirmed uncomplicated Cutaneous Leishmaniasis.
This Phase 2 study is to determine whether WR279396 with occlusion (a polyurethane dressing) is more effective than WR279396 without occlusion for once daily treatment. Extensive objective and subjective local tolerance data will also be captured during this trial, as well as surrogate markers (parasite loads and aminoglycosides concentration in the deep dermis) that may help to determine the optimal number and duration of treatments. The results from this study will help determine the most practical treatment schedule and will answer questions that are crucial to improve the present treatment regimen with WR279396 which is twice a day for 20 days.
