Active clinical trials for "Malaria"

This is a two-arm study aiming at recruiting 150 patients to assess the efficacy of Amodiaquine-Artesunate (ASAQ) and Artemether-Lumefantrine (AL) in patients with a microscopy positive diagnosis of malaria in Nanoro, Burkina Faso and assess the performance of the Rapid Diagnosis Tests (RDTs) compared to the microscopy.

The purpose of this study is to demonstrate that ArTiMist (sublingual artemether spray) is better than intravenous quinine in reducing parasite counts by >= 90% within 24 hours after the start of treatment in children with severe malaria, or uncomplicated malaria with gastrointestinal complications

This study is an evaluation of the benefit of adding artesunate to existing first and second line antimalarial therapies in Pakistan. A placebo controlled trial was carried out to assess two potential benefits of Artesunate Combination Therapy (ACT): efficacy and potential for transmission reduction.

Malaria is the most important human parasitic disease and is responsible of high morbidity and mortality in resource-poor countries. Pregnant women, who are a high-risk group, are almost always excluded from clinical trials; thus, the investigators lack sufficient information on the safety and efficacy of most antimalarials in pregnancy. The recommendation of the World Health Organization to use artemisinin combination therapy (ACT) in the 2nd and 3rd trimester is already implemented in several African countries, however documentation of their efficacy and safety in pregnancy is still limited. Thus, the investigators propose to evaluate the efficacy and safety of 4 ACT(artemether-lumefantrine, amodiaquine-artesunate, mefloquine-artesunate and dihydroartemisinin-piperaquine), when used to treat pregnant women with P. falciparum malaria; the results will help to recommend the optimal therapy for this high-risk group in Africa.

Previous investigations indicate that methotrexate, an old anticancer drug, could be used at low doses to treat malaria. This is a phase I evaluation to assess the safety and pharmacokinetic profile of this drug in healthy adult male Kenyan volunteers.

Resistance to antimalarial drugs represents a major obstacle for controlling malaria in endemic countries, so that most sub-Saharan countries have changed their antimalarial drug policy to the new Artemisinin Containing Therapies. Burkina Faso has changed its policy for uncomplicated malaria to Artemether-Lumefantrine (AL) and Artesunate-Amodiaquine (AQ+AS), but there are still little available data on safety and efficacy of these treatments in Burkina Faso; both treatments have shown to be efficacious, but AL seems to have higher occurrence of recurrent malaria infections during a 28-day follow up period. Thus, this study aims at comparing the safety and efficacy of AL and AS-AQ (42-day follow-up), AND also at comparing their in vitro sensitivity, in patients with recurrent infection, with the results obtained in vivo.

Assess the efficacy of 2 grams of tinidazole given for 5 days with standard dose chloroquine to achieve radical cure of Plasmodium vivax within a 90 day follow-up period sufficient to justify an IND and formal phase II evaluation.

Primary objective is to demonstrate the non-inferiority of PCR (Polymerase Chain Reaction) adjusted adequate clinical and parasitological response at Day 28 of Coarsucam versus Coartem, based on the first malaria attack of each patient. Secondary objectives: For the first attack: To compare the 2 groups of treatment in terms of: Day 42 efficacy Parasitological and fever clearance Clinical and Biological tolerability Evolution of gametocyte carriage For attack 2nd and following: To compare the 2 groups of treatment in terms of: Day 28 and Day 42 clinical and parasitological effectiveness Clinical and Biological tolerability Proportion of patients without fever at Day 3 Proportion of patients without parasites at Day 3 Evolution of gametocyte carriage Compliance During the total follow up of the cohort: To compare the 2 groups of treatment in terms of: Treatment incidence density Impact of repeated treatment on clinical and biological tolerability Impact on anaemia Impact on Hackett score.

Primary objective: to demonstrate the non-inferiority of PCR adjusted adequate clinical and parasitological response at D28 of artesunate + amiodaquine versus artemether + lumefantrine, based on the first malaria attack of each subject. Secondary objectives: For the first attack: To compare the two groups of treatment in terms of: D14 efficacy Parasitological and fever clearance Clinical and biological tolerability Evolution of gametocyte carriage Cardiac tolerability (QTc) For the repeated attacks: To compare the two groups of treatment in terms of: D14 and D28 clinical and parasitological effectiveness (PCR adjusted) Clinical and biological tolerability Proportion of patients without fever at D3 Proportion of patients without parasite at D3 Compliance Impact on anaemia During the total follow-up of the cohort: To compare the two groups of treatment in term of: Treatment incidence density Impact of repeated treatment on clinical and biological safety Impact of repeated treatment on hearing capacity

The purpose of this open randomised multi-centre clinical trial is to test the hypothesis that three pills of the fixed dose combination artesunate/sulfamethoxypyrazine/pyrimethamine, administered over 24 hours is not inferior in efficacy to the same drug administered over 48 hours and that the fixed dose combination artesunate/sulfamethoxypyrazine/pyrimethamine As/SMP fdc, independently of the duration of its dose interval, is not inferior in efficacy to 6 - 24 pills (number of pills administered to respectively children and adults)of the 60 hours treatment of artemether/lumefantrine for the treatment of uncomplicated P. falciparum malaria.
