Active clinical trials for "Malaria"

Objective: Measure incidence of malaria and malaria-related outcomes, evaluating potential impact of the SARS-CoV2 epidemic and of antimalarial resistance in Oyam and Kole district, Uganda with focus on pregnant women. Study design: Facility-based, prospective, observational study. Study population: All pregnant women at any gestational age presenting to the Aber Hospitals during the study period both at the emergency department or the Ante-Natal Care (ANC) clinic will be eligible to participate in this study. Methods: Women will be recruited at ANC visits and at the emergency department and screened against the inclusion criteria. Women will be followed until delivery and evaluated during the consecutives ANC visits. Outcomes will be assessed at the delivery or/and at the discharge if admitted to the hospital for any other causes related with the pregnancy or the malaria. Also, a subpopulation of nonpregnant individuals diagnosed with malaria will be recruited for resistance detection. Main study parameters/primary endpoints: Incidence of malaria and malaria-related adverse outcomes; impact of the COVID-19 pandemic on malaria care; prevalence of antimalarial resistance against artemisinin derivatives and sulphadoxine-pyrimethamine.

This study assessed the effect of multiple doses of a moderate inducer of cytochrome P450 (CYP) 3A4 (efavirenz) on the pharmacokinetics (PK) of ganaplacide and lumefantrine combination. Results from this study will provide guidance on prescribing ganaplacide and lumefantrine combination when co-administered with moderate inducers of CYP3A4.

The Democratic Republic of the Congo (DRC) is among the countries most affected by malaria in Sub-Saharan Africa. Condidering its size and the geographic position, the DRC is meant to play a major role in the malaria control in the region. The National Malaria Control program recommends artemisinin-based combination treatments (ACTs), in particular artesunate-amodiaquine or artemether-lumefrantrine for the treatment of uncomplicated malaria. Previous studies indicated that ACTs are still effective, with efficacy above the required threshold of 90%. It is required to assess regularly the efficacy of antimalarial drugs, in order to ascertain the relevance of treatment guidelines such that, in case of increasing failure rates, alternative options can be decided ontime. The purpose of this trial is to assess efficacy and safety of artesunate-amodiaquine (ASAQ Winthrop®), artemether-lumefantrine (Coartem Dispersible®) and dihydro-artemisinin-piperaquine (Eurartesim®) at day 42 in the treatment of uncomplicated Plasmodium falciparum malaria in six surveillance sites around DRC.

The purpose of the study is to evaluate and compare the efficacy of parenteral artesunate with three quinine regimens in the treatment of severe malaria in children at the Ebolowa Regional Hospital located in the South region of Cameroon

Iron deficiency and iron deficiency anemia (IDA) are the most prevalent micronutrient deficiencies on a worldwide basis, especially in developing countries. The impact of severe IDA can have mortal consequences, since without adequate hemoglobin, the brain and body become deprived of oxygen and, if allowed to continue, death may ensue. It has been shown that iron supplementation in infants and young children can enhance child development, however, it may also result in increased rates of malaria in high burden areas. The primary objective of this study is to determine the impact of providing encapsulated iron (as a powder added to complementary foods) on the susceptibility to clinical malaria among anemic and non-anemic infants and young children (6-24 months of age) living in a high malaria burden area. The value of performing this research in Ghana is primarily that malaria and anemia remain the most important causes of death and morbidity.

Background: There are worrying signs from Western Cambodia that parasitological responses to artesunate containing treatment regimens for uncomplicated falciparum malaria are slower than elsewhere in the world. Delayed parasite clearance and unusually high failure rates with artesunate-mefloquine have been reported. These antimalarials are central to current treatment strategies and spread of significant resistance outside this area would be a global disaster. Radical containment measures are needed. In this context there is an urgent need to proceed quickly to investigate whether there is any evidence of resistance to artemisinin derivatives in Vietnam. Objective: The primary objective is to assess the slope of the decline in the log parasitemia-time curve in patients treated with artesunate 2mg/kg/day, artesunate 4mg/kg/day or dihydroartemisinin-piperaquine once daily, and to compare the results of this study to the pharmacokinetic results and to the recent data from patients in Cambodia and Thailand treated with equivalent therapies. Methods: The trial will be conducted in Phuoc Long Hospital, Binh Phuoc Province, Vietnam. The participants will be febrile patients (aged > 10 years) with slide confirmed uncomplicated P. falciparum infection. Patients will be treated with either artesunate 2mg/kg/day, artesunate 4mg/kg/day or dihydroartemisinin-piperaquine once daily for 3 days. Patients on artesunate therapy arms will then receive 3 days of treatment with dihydroartemisinin-piperaquine with dosages according to the national guidelines. Clinical and parasitological parameters will be monitored over a 42-day follow-up period. The pharmacokinetic characteristics of artesunate and dihydroartemisinin will be assessed by using a population pharmacokinetic modeling.

In this stdy, patients aged above 6 months with symptomatic malaria presenting to health centers will be enrolled for treatment with artemether-lumefantrine for P. falciparum infection, and either artemether-lumefantrine or chloroquine for P. vivax infection. Clinical, parasitologic, and hematologic parameters will be monitored for P. falciparum and P. vivax infection over a 42-day follow-up period, which will be used to evaluate drug efficacy. Results from this research study will be used to assist Ethiopia in assessing their current national malaria drug policies.

The purpose of this study was to evaluate the effectiveness of the fixed combination of artesunate+mefloquine in the treatment of uncomplicated malaria caused by Plasmodium falciparum in the municipality of Cruzeiro do Sul, Juruá Valley, Brazil, where it was being used as specific first-line drug.

Riamet® or Malarone® are both recommended as the first line treatment for uncomplicated malaria in France, according to the French consensus Conference revised in 2007 on the treatment of imported malaria. The aim of the study is to compare both tolerance and efficacy of Malarone® and Riamet® in the treatment of uncomplicated imported malaria and to determine clinical and parasitological predictive factors associated with a less effectiveness. It's a multicentric, randomised study in adults with uncomplicated malaria. Treatment will be administered for 3 days, and patients will be followed for 28 days, to evaluate the therapeutic evolution. 640 patients will be included among 15 centres.

More than 1.5 million deaths of African children under 5 years of age have been due to Plasmodium falciparum malaria. When HIV and malaria are present as coinfections, they enhance each other's progression. The primary purpose of this study is to compare the malarial infection levels in HIV-infected infants and children receiving protease inhibitor (PI)- or non-nucleotide reverse transcriptase inhibitor (NNRTI)-based highly active antiretroviral therapy (HAART).
