The purpose of this study is to determine the safety and efficacy of sulfadoxine-pyrimethamine (SP) versus artemether-lumefantrine (Coartem) when administered to HIV+ and HIV- patients with uncomplicated P. falciparum malaria. Patients will be randomised to one of the 2 treatment and followed up (until day 14 actively) for 45 days.
The purpose of this study is to evaluate the efficiency of a rapid diagnostic test (Paracheck Pf) for the diagnosis of uncomplicated Plasmodium falciparum malaria by community health workers at village level in Tanzania and how the use of rapid diagnostic test may influence prescription of antimalarial drugs. The hypothesis is that rapid diagnostic tests used by community health workers will reduce the use of antimalarial drugs (Coartem; Novartis) by 30% without affecting the health outcome.
The purpose of this study is to study resistance to current malaria treatments and affordable alternatives for uncomplicated malaria. Resistance occurs in areas where these treatments are used frequently. This study may help prevent future resistance. About 150 residents in Buenaventura, Colombia will participate. They will have uncomplicated malaria and they will be followed for 28 days after treatment. Physical exams and blood draws are included in study visits.
The goal of this study is to develop a safe, well tolerated, and highly efficacious azithromycin combination treatment for uncomplicated falciparum malaria. Azithromycin is a drug that has shown potential for malaria treatment. It will be combined with other malaria drugs currently approved for treatment in Thailand. About 120 people, ages 20-65, will be enrolled in Thailand. Participants will have severe cases of malaria and they will be hospitalized 28 days for treatment.
Treatment of uncomplicated P.falciparum malaria with sulfadoxine-pyrimethamine (SP) is followed by a marked increase in the density of gametocytes. To determine whether treatment with SP enhances gametocyte carriage, we randomized asymptomatic carriers of P.falciparum to receive SP alone, SP with a single dose of artesunate, or placebo, and followed them for 56 days to record gametocyte presence and density.
Shanghai Wanxing Bio-Pharmaceuticals is currently evaluating one malaria vaccine candidate, PfCP2.9 adjuvanted with Montanide ISA 720. This trial is designed to test the safety and immunogenicity of 3 doses and 2 vaccination schedules. This blood stage candidate malaria vaccine is being developed for the routine immunization of infants and children living in malaria-endemic areas.
The treatment of symptomatic, uncomplicated malaria caused by P. falciparum in adults.
Design: Single-centre Indication: Malaria caused by Plasmodium falciparum Objectives: To determine and compare the efficacy of AQ treatment in young children with uncomplicated falciparum malaria in the rural and the urban study area of the Centre de Recherche en Santé de Nouna (CRSN). Population: Children aged 6-59 months with uncomplicated falciparum malaria (axillary temperature ≥ 37.5°C + ≥ 2.000 P. falciparum asexual parasites per µl blood) from the health centre situated in the villages of Bagala, Bourasso and Kemena and from Nouna town hospital outpatient department. Sample size: N=120 Treatment: All children will receive a total dose of 25 mg/kg oral AQ over a period of three days (first and second day: 10mg/kg, third day: 5mg/kg). Statistical procedures: The primary analysis parameter is the proportion of clinical failures on day 14. Secondary parameters are the rate of clinical failures on day 28 (with and without PCR correction), the rate of early clinical failures, the rate of late parasitological failures (day 14 and day 28), and the rate of adverse events. Data will be analysed in the overall group of study children and for rural (n=50) and urban (n=50) study children separately. Study duration and dates: The study will be implemented in September-December 2005.
Treatment of Plasmodium falciparum malaria in Africa is increasingly difficult. Resistance to cheap efficient antimalarial drugs poses an increasing threat. The rapid emergence of resistance to sulfadoxine - pyrimethamine, already seen in East Africa is growing and is likely to have an striking impact on mortality in many other African regions where no obvious alternatives are available. WHO recommends the use of drug combinations containing artemisinin compounds, i.e., artemisinin-based combination therapies (ACT). Previous clinical trials have shown that the combination of artesunate with mefloquine is highly effective and well tolerated in the treatment of multidrug-resistant falciparum malaria, retaining the benefit of rapidity of action while augmenting cure rates, and apparently slowing the development of mefloquine resistance. Compliance with sequential combination regimen of antimalarial drugs is notoriously poor. Therefore, in order to limit the development of resistance to both drugs and ameliorate patients' compliance to antimalarial treatments, an optimal simultaneous combination regimen of artesunate and mefloquine in a practical single blister pack has been developed by Mepha Ltd. and successfully tested. The currently available
