Filter by:The purpose of this study is to investigate the impact of rapid diagnostic tests (RDTs) in the context of a newly implemented malaria case management guidelines using artemisinin-based combination therapy on the malaria prescribing practices of health care workers in Kenya.
The purpose of this explorative clinical trial is to study parasite population dynamics, diversity and clearance kinetics of Plasmodium falciparum as well as determination of the molecular mechanisms associated with drug resistance during the early phase of artemether-lumefantrine treatment when the drug intake is either accompanied with or without intake of fatty food. The hypothesis is that intake of fatty food together with artemether-lumefantrine will enhance parasite clearance and thereby decrease the risk of early selection of genetic markers related to drug resistance. The study population is children aged 1-10 years with uncomplicated malaria in Bagamoyo District, Tanzania. Enrolled children will be randomly allocated to either intake of a fatty meal or not together with the study drug. Artemether-lumefantrine will be given twice daily for 3 days in standard doses according to bodyweight. Study participants will be admitted during the study period (3 days)to allow close supervision and detailed blood sampling.
The main purpose of this study is to compare the drug levels of artesunate and sulfadoxine-pyrimethamine found in pregnant women with malaria to those drug levels found in non-pregnant women from other studies. In addition the efficacy and safety of the study drugs will be determined for pregnant women and their babies.
The purpose of this study is to evaluate three dose levels of a combination tablet and a fixed dose granule formulation of pyronaridine and artesunate (PA) for the treatment of acute uncomplicated falciparum malaria in children.
In areas of seasonal malaria transmission, treatment of carriers of malaria parasites, whose parasitaemia persists at very low levels throughout the dry season, could be a useful strategy for malaria control in areas with a short transmission season. We did a randomized trial to compare two regimens for clearance of low level parasitaemia in the dry season.
No pediatric formulations of quinine exist. Therefore, quinine tablets are broken into 2 or 4 parts, according to the body weight. Based on the body weight, 1/2 or 1/4 a tablet is administered to the child. At this moment, quinine sulphate pellets are developed. These pellets enable an adequate dosing according to the body weight. 56 children with malaria will be dosed every 8 hours during 7 days with 10-15mg/kg body weight.
Malaria remains a disease that causes much death and sickness, especially in sub-Saharan Africa. An accurate, simple, and inexpensive method of diagnosing malaria is urgently needed. The purpose of this study is to evaluate a different diagnostic method compared to those most frequently used. The study may also identify the factors causing false positive and false negative results using the alternative method. Participants will be 600 Ugandan children aged 1-10 years who are enrolled in protocol 04-068. Those who develop a fever over the 12 month duration of the study will be tested for malaria by both the standard and the new methods. These tests will require a few drops of blood to be collected by finger prick. Subjects will be treated on the basis of standard diagnostic testing (i.e. expert microscopy).
The RTS,S/AS02A vaccine (or GSK 257049 vaccine), GSK Biologicals' candidate Plasmodium falciparum (P. falciparum) malaria vaccine is being developed for the routine immunization of infants and children living in malaria endemic areas. The vaccine would offer protection against malaria disease due to the parasite P. falciparum. The vaccine would also provide protection against infection with hepatitis B virus (HBV). This phase IIb trial is being carried out following the demonstration of efficacy of the candidate malaria vaccine in children in Mozambique: there, the vaccine demonstrated approximately 30% efficacy against clinical episodes of malaria and approximately 58% efficacy against severe malaria disease. In this study, the children from Mozambique (NCT= NCT00197041) are followed-up to assess the safety, immunogenicity and efficacy of the candidate malaria vaccine for a two year period commencing 21 months after Dose 1. This protocol posting deals with objectives & outcome measures of the extension phase at year 2. During this extension study, no new subjects will be recruited and no vaccine will be administered. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The purpose of this protocol is to perform Phase 1 (safety/toxicity and pharmacokinetic) Studies of an investigational aminoquinoline antimalarial (AQ-13) in human subjects. The compound to be studied (AQ-13) is being examined because it is active in vitro against Plasmodium falciparum malaria parasites resistant to chloroquine (CQ) and other antimalarials (multi-resistant P. falciparum), and because its safety was similar to that of CQ in preclinical studies performed by SRI International (IND 55,670). AQ-13 was also selected for study because it is active in vivo in two monkey models of human malaria: 1] P. cynomolgi in the rhesus monkey (Macaca mulatta), a model of human infection with P. vivax, and 2] CQ-resistant P. falciparum in the squirrel monkey, a model of human infection with CQ-resistant P. falciparum.
The purpose of this study was to assess the safety and efficacy of Cotrifazid to treat uncomplicated resistant malaria and to compare the outcome with mefloquine or quinine+sulfadoxine/pyrimethamine (SP)
