View clinical trials related to Falciparum Malaria.
Filter by:Malaria is caused by protozoan parasites of the genus Plasmodium and it is the most important parasitic disease in terms of mortality and morbidity. Estimates of 247 million malaria cases and 619.000 deaths worldwide were reported by WHO for the year 2021 (1). Plasmodium falciparum can lead to severe malaria and accounts for 90% of malaria deaths that mainly occur in children below the age of 5 years in Sub-Saharan Africa. A simplified treatment regimen, ideally a single-day cure (or at most 2-day dosing regimen), of uncomplicated malaria due to P. falciparum would be the magic in the antimalarial armamentarium. Improving treatment adherence is one of the key factors in reducing mortality and morbidity and also the transmission of malaria, and such a regimen would substantially increase adherence. To find a new non-artemisinin combination therapy with a shorter regimen, ideally, a single-dose cure, with low resistance potential would be the aim. The two compounds tested here are ZY19489, a triaminopyrimidine, and ferroquine (FQ), a next-generation 4-aminoquinoline. Both compounds show unique features in terms of long half-life, and activity against current drug-resistant strains. Therefore, the main goal of this clinical trial is to assess the safety of the ZY19489-FQ combination given as a 1- or 2-day dose regimen.
Malaria remains a major public health concern in Cameroon especially among vulnerable groups such as children less than five years and pregnant women. Artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL) have been used for the treatment of uncomplicated Plasmodium falciparum in Cameroon since 2004. Worldwide, several studies among children have reported high efficacy and safety of artemisinin-based combination therapies (ACTs). There is paucity of data to support the continuous use of ASAQ and AL in Cameroon. The main objective of this study is to assess the efficacy and safety of artesunate-amodiaquine and artemether-lumefantrine during a 28-day follow-up period in children with acute uncomplicated P. falciparum malaria in the Center Region of Cameroon. A randomized, open-labelled, controlled clinical trial comparing artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL) will be carried out from 5th April to 31st December, 2021 at six hospitals in the Center Region of Cameroon. The study participants shall include febrile patients aged 6 months to 10 years with confirmed uncomplicated P. falciparum infection. Eligible children for whom parent/guardian informed consents are obtained will be randomized to receive either artesunate-amodiaquine (group A) or artemether-lumefantrine (group B) in the ratio 1:1. A minimum sample of 76 patients will be required for the study. With a 20 % increase to allow loss to follow-up and withdrawals during the 28-day follow-up period, 92 patients will be enrolled for each of the two study arms. The study will recruit a total of 184 patients. However, since 6 sites will be involved, a minimum of 30 participants shall be enrolled per site. Drug intake will be done under strict supervision on days 0, 1 and 2. Follow-up visits will be performed on days 3, 7, 14, 21, and 28 to evaluate clinical and parasitological resolution of their malaria episode as well as adverse events. Polymerase chain reaction (PCR) genotyping of merozoite surface proteins 1 and 2 (msp-1, msp-2) as well as glutamate rich protein (GLURP) will be used to differentiate between recrudescence and new infection.
