Filter by:Malaria is a disease that affects many people in Africa. Malaria is caused by germs spread by mosquito bites. The purpose of this study is to compare the number of children who get malaria after receiving an experimental malaria vaccine (FMP2.1/AS02A) to the number of children who get malaria after receiving a vaccine for rabies (an approved vaccine that does not prevent malaria). The children will be assigned to one of the vaccine groups by chance. Participants and doctors will not know which vaccine was given. Study participants will include 400 children, ages 1-6 years, living in Bandiagara, Mali. Children will receive 3 vaccine doses, by injection, to their upper arm. Study procedures will include physical exams and several blood samples. Participants will be involved in the study for 26 months.
Malaria is a life-threatening disease especially in small children. A high degree of Plasmodium falciparum resistance to chloroquine has already spread to South-Benin where this study is taking place. In the past few years, the recommendation for a first-line treatment in this area has moved from chloroquine to sulfadoxine-pyrimethamine (SP). There is growing evidence that Plasmodium falciparum resistance to SP has come to South-Benin. The aim of the study is to compare the efficacy of SP to two compact artemisinin-based therapies (ACT): artemether-lumefantrine and the amodiaquine-artesunate coformulation. ACT will be unsupervised. The primary endpoint is an effectiveness comparison (PCR corrected) at day 28. Secondary outcomes are effectiveness comparisons (PCR corrected) at day 14 and 42 and a study on the relationships between ACT PK data (day 3) and outcome. Expected total enrollment: 225 patients Study start: April 2007; expected completion: December 2007
The purpose of this study is to compare four regimens using US FDA GMP intravenous artesunate for the treatment of uncomplicated Plasmodium falciparum malaria to identify the most effective treatment regimen as determined by rapidity of parasite clearance by microscopy.
The purpose of this study is to test the safety of a 2100 mg dose of AQ-13, a new candidate antimalarial active against drug-resistant P. falciparum infection, and to determine the effect of a standard fatty meal on the absorption of the drug from the gut and its blood levels.
The purpose of this clinical trial is to assess the effectiveness of artemether-lumefantrine (Coartem®) treatment provided by community health workers against uncomplicated malaria in children under 5 years of age in Kibaha District, Tanzania, during an extended follow-up of 42 days. The hypothesis is that artemether-lumefantrine treatment provided by community health workers will result in less than 85% PCR-corrected parasitological effectiveness by day 42, mainly due to partial non-compliance to full standard 6-dose regimen of the drug.
IPTi, a strategy whereby infants are provided treatment doses of antimalarials at routine vaccination visits, has been shown to significantly reduce malaria and anemia in two studies in Tanzania. However the results obtained in Gabon are not similar. Many factors are likely to influence the efficacy or effectiveness IPTi. It is reasonable to assume that the efficacy of IPTi will be influenced markedly by the sensitivity of Plasmodium falciparum to the antimalarial drug (Sulfadoxine-Pyrimethamine) used for IPTi. In order to interpret the results of individual IPTi trials conducted by the IPTi Consortium, and to provide information for policy makers regarding the predicted efficacy of IPTi, it is essential to obtain information on antimalarial drug sensitivity of Sulfadoxine-Pyrimethamine now that the IPTi trial has been conducted. The simplest and most universally accepted measure of testing for antimalarial drug efficacy is the "in vivo efficacy study," which follows a standardized World Health Organization protocol. A second reason for evaluating drug resistance as an adjunct to the IPTi trials is to determine if the intervention increases the carriage and/or spread of drug resistant P. falciparum parasites. Thirdly the overall effect at the community level of selection of resistant genotypes in IPTi-recipients is unclear.
Test the hypothesis that repeated administration of Artesunate/Amiodaquine, Artesunate/Sulfadoxine-Pyrimethamine and Arthemeter-Lufemantrine for the treatment of consecutive episodes of uncomplicated malaria reduces the incidence of uncomplicated falciparum malaria and malaria attributable anemia
This will be a study of the safety of MSP 3 LSP candidate malaria vaccine in children aged 1-2 years in Burkina Faso. Three imminizations at 28 day intervals will be administratered subcuteneously on the shoulder region. The study will compare MSP3 with Engerix B vaccine to evaluate whether it is just as safe to give to children in malaria endemic country. The study will also evaluate whether the vaccine induces the expected immune responses. Two dose levels of MSP 3 will be evaluated; 15µg and 30µg to determine the one with the best safety and immune response profile.
The annual number of cases of clinical malaria worldwide is estimated to be 300-500 million leading to 1.5 million deaths. Delayed care and frequent drug resistance of Plasmodium falciparum (Pf), the most frequent form of malaria, is responsible for these deaths. Each year, 5000-8000 travellers return to France with malaria, 4/5 from Africa and with Pf. Clinical features associated with a malaria crisis are poorly predictive and misdiagnosis can be easily made. Diagnosis of accurate malaria rely on microscopic examination of stained thin and thick blood films by a well trained microscopist. Few emergency wards are specialized for tropical diseases. For most of them, malaria is a rare disease and hours are lost before accurate microscopy can permit the decision
The purpose of the study is to evaluate the potential side-effects of artemether / lumefantrine and other antimalarials on the auditory function.
