The purpose of this randomized, open label clinical trial is to determine if oral miltefosine is a safe and effective alternative, compared with parenteral meglumine antimoniate for the treatment of pediatric Cutaneous caused by L. Viannia species in Colombia.
The purpose of this study is to determine if a vaccine (called Leish-111f + MPL-SE) is safe and whether it can or cannot produce a protective response against visceral leishmaniasis when injected to healthy subjects.
Background: Cutaneous Leishmaniasis is a worldwide disease, endemic in over 88 countries, that has shown an increasing incidence over the last many decades. For the last 60 years antimony compounds are considered the treatment of choice. Though their use is expensive, cumbersome, has many adverse effects and not effective in all patients, the search for a better alternative is still going on. Low dose antimony compounds in combination with several agents have shown promise of reducing adverse effects of antimony compounds without compromising efficacy. Allopurinol is one such agent which though promising lacks randomized, controlled trials to prove efficacy. The main objective of this study is to evaluate low dose sodium stibogluconate in combination with allopurinol and to compare it with high dose sodium stibogluconate in terms of efficacy and adverse effects. Methods and design: A multi-center randomized, controlled trial including 620 patients from endemic areas for Leishmaniasis in Pakistan will be undertaken to assess the research question. Parasitologically confirmed cutaneous leishmaniasis will be included in the study. After evaluating the inclusion/exclusion criteria patients will be randomized to receive either meglumine antimoniate (20 mg/kg/day/intramuscular, till clinical resolution or a maximum of 28 days) or combination of meglumine antimoniate (10 mg/kg/day intramuscular) and allopurinol (20 mg/kg/day/oral) till clinical resolution or a maximum of 28 days. During treatment patients will be admitted to hospital and monitored daily for the presence of adverse effects. Follow up period will last six months during which patients will visits the research centers for assessment of healing process at monthly intervals.
Cutaneous leishmaniasis (CL) is a worldwide disease, endemic in 88 countries, that has shown an increasing incidence the last two decades. It is estimated that in 2005, about of 20,000 new cases of CL were diagnosed in Colombia. 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 adverse events and disadvantages. Previous studies have shown that miltefosine could be a potential alternative of treatment for CL. The main objective of this study is to evaluate the efficacy and safety of miltefosine or thermotherapy for the treatment for CL. In this study the efficacy of oral treatment of miltefosine 150 mg/day for 28 days or a thermotherapy device used for one session at 50 celsius degrees during 30 seconds will be compared with the standard treatment of intramuscular injections of 20 mg/Kg/day of pentavalent antimonials (GlucantimeÒ) for 20 days in CL parasitologically proven patients. This trial will be conducted according to the International approved GCP (Good Clinical Practice) guidelines.
The purpose of this project is to investigate the efficacy of early, empiric anti-helminthic therapy combined with standard pentavalent antimony in the treatment of subjects co-infected with helminths and cutaneous leishmaniasis caused by L. brasiliensis. The study hypothesis is that early intervention with antihelminthic therapy will improve response rates to antimony in subjects with cutaneous leishmaniasis.
The purpose of this study is to determine how the body defends itself against Leishmania (Viannia), a parasite that can cause a skin infection and skin sores. Certain cells in the immune system act more aggressively against Leishmania in people with mild Leishmania symptoms than in those who have long-term or recurring symptoms of the disease. Participants in the study will include people who currently have Leishmania infection, people who have had the infection in the past, and people who have never been exposed to the parasite. This study will enroll 220 adults, ages 18 to 70 years, at 3 sites in Colombia. Blood samples will be collected from volunteers at least once during the study. Participants will also undergo HIV testing. Volunteers will participate in up to 2 study visits, scheduled 2-3 weeks apart.
CIDEIM, Centro Internacional de Entrenamiento e Investigaciones Medicas, is conducting a research study about the disease Cutaneous Leishmaniasis, which is caused by the Leishmania parasite and causes skin sores. Researchers hope to find out how the human body defends against Leishmania. A total of 472 individuals, ages 7 to 70 years, belonging to one of the following groups will be included in this study: recurring disease, chronic disease, disease with no sign or symptoms (asymptomatic), and healthy individuals. Study procedures will include a questionnaire and buccal swab (swabbing of the inside of the cheek with a cotton or wooden applicator). In addition, asymptomatic and healthy individuals will provide a blood sample. Study participation will be up to 1.5 hours.
The purpose of this study is to determine what types of cells participate in the defense of humans against Leishmania (skin parasites). People 18-70 years of age who have leishmaniasis, have healed leishmanial lesions, or are healthy are being invited to participate in this study. Approximately 150 people will participate in the study. Participants will be asked to provide some general information about themselves and about skin sores, if they have any. A skin test will be performed and a blood sample will be obtained. This study involves up to 3 visits; the first visit will last up to 5 hours and the second visit will last for 30 minutes. The third visit may be scheduled within 3 days after the second visit.
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.
