Active clinical trials for "Malaria, Falciparum"

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

Primary Objective: To demonstrate the non-inferiority, in terms of clinical and parasitological efficacy on D28 of administration of Coarsucam™ (artesunate+amodiaquine fixed-dose combination), as a single daily dose, in comparison with administration of Coartem® (artemether+lumefantrine). Secondary Objectives: To compare the 3 treatment groups in terms of: clinical and parasitological efficacy on D14 and D28 on the global population and on the subpopulation consisting of children aged under 5 years and that for patients aged 5 years and over clinical and laboratory safety time to parasite clearance time to clearance of fever changes in gametocytaemia impact on anaemia

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.

Children participating in a study evaluating the efficacy of chloroquine and amodiaquine for the treatment of malaria will, if getting malaria during follow-up, be re-treated with sulfadoxine-pyrimethamine (SP) in accordance with the recommendations of the National Malaria Programme. To compare the actual efficacy of SP with that in 1995 - 1996 we, the investigators of the Bandim Health Project, will visit these children once a week for 5 weeks. A finger prick blood sample will be collected for a malaria test. Children with malaria during follow-up will be treated according to the guidelines of the Bandim Health Centre.

The primary objective is to confirm the hypothesis that azithromycin plus chloroquine is non-inferior to atovaquone-proguanil for the treatment of symptomatic, uncomplicated malaria due to P. falciparum.

The primary objective is to confirm the hypothesis that azithromycin used in combination with chloroquine is non-inferior to artemether- Lumefantrine for the treatment of symptomatic, uncomplicated malaria due to P. falciparum in children in African countries.

The purpose of this study was to provide stronger evidence for extended-dose chloroquine treatment of falciparum-positive Afghan refugees in Northwest Frontier Province (NWFP), Pakistan or justification for discontinuation of the policy.

The treatment of symptomatic, uncomplicated malaria caused by P. falciparum in adults.

Anemia is still a main public health problem in sub-Saharan Africa. Anemic women have an increased maternal and perinatal mortality and anemic adults have diminished work capacity. In sub-Saharan Africa, the etiology of anemia is multifactoral; the major causes are low dietary bioavailability and chronic parasitic infections such as malaria. These causes are likely to interact because infection and infection-associated inflammation may impair the utilization and absorption of iron. Therefore, the control of parasite infections may be important to improve iron bioavailability from foods. Malaria infections are endemic in northern Benin. To investigate the contribution of asymptomatic malaria (a positive blood smear for malarial parasites but without clinical symptoms of fever, headache or malaise) to anemia, we are planning a human iron absorption study in Benin. We will recruit adults with asymptomatic malaria infection. The iron absorption and utilization of the study subjects will be studied while infected, then they will be treated to clear their infections, and then iron absorption and utilization will be restudied. Iron absorption will be determined by incorporation of labeled iron into erythrocytes, 14 days after the administration of a test meal containing labeled iron (stable isotope technique). Subjects will be men and non-pregnant, non-breastfeeding women with a body weight < 65 kg and between the age of 18 - 30 years. The results of this study will provide important information on the influence of malaria infections on iron absorption and utilization in humans. The study will provide insight into the potential necessity of malaria control to ensure iron bioavailability from foods in developing countries.

The purpose of this study is to determine bioequivalence of amodiaquine suspension ( Pfizer) and the WHO approved reference product Flavoquine® tablet ( Sanofi Aventis).
