Active clinical trials for "Malaria, Falciparum"

The purpose of the INTREPiD study is to compare 1st trimester screening for malaria parasites with a high-sensitivity malaria rapid diagnostic test followed by treatment of test-positive women with artemether-lumefantrine (AL) against usual antenatal care on a composite adverse pregnancy outcome including low birth weight, small for gestational age, preterm, fetal loss, or neonatal death.

Currently, the first-line combination of artemisinin, piperaquine and prima-quine is quite effective in controlling malaria, however, the threat of spread of drug-resistant parasites has been reported. A study is conducted to assess the efficacy and safety extract of bitter melon (Momordica charantia/MC) regimens compared to the combination of dihydroartemisinin piperaquine primaquine (DHP+PQ) on the sexual and asexual stage of P. Falciparum uncomplicated in Sumba Barat Daya District, Indonesia

This is an open-label, single-centre, non-randomized study to investigate the pharmacokinetics of GSK3191607, administered as a single intravenous (IV) dose in healthy male subjects. Six subjects will be administered an IV microdose of radio-labeled [14C]-GSK3191607. The study will provide an early readout on human pharmacokinetic parameters. The results of this study will be used to estimate the potential duration of anti-parasite effect in humans, define predicted clinical oral doses, and hence inform about the compound's potential safety margin. Each subject will participate in the study for up to 8 weeks, and will have a screening visit, one treatment period, eight outpatient visits, and a follow-up visit.

This is a prospective, open label, randomised controlled trial to assess the safety and efficacy of dihydroartemisinin-piperaquine and artemether-lumefantrine in children and adults with uncomplicated Plasmodium falciparum malaria infection. Molecular markers for antimalarial resistance will also be assessed and the presence of molecular markers in the parasites will be associated with treatment outcomes.

The World Health Organization recommends regular surveillance of antimalarial efficacy to monitor the performance of different drugs. The Tanzanian National Malaria Control Programme (NMCP) in collaboration with its partners have been implementing therapeutic efficacy studies (TES) to monitor the performance of different antimalarials in the country. Most of the studies conducted in recent years focused on artemether-lumefantrine which is the first line antimalarial for the treatment of uncomplicated malaria in Mainland Tanzania. However, data on the performance of other artemisinin based combination therapy (ACTs) is urgently needed to support timely review and changes of treatment guidelines in case of drug resistance to current regimen. This study was undertaken in the same NMCP framework to assess the efficacy and safety of alternative ACTs used or with potential use in Tanzania. The study assessed the efficacy and safety of artesunate-amodiaquine (ASAQ) and dihydroartemisinin-piperaquine (DP) for the treatment of uncomplicated malaria in Tanzania. The study was undertaken at two NMCP sentinel sites of Kibaha and Ujiji from July to December 2017.

The primary objective of the study was to determine PCR corrected cure-rates up to day 42 in children with uncomplicated malaria, treated with either Artesunate + Amodiaquine or Coartem®. Secondary objectives were to determine safety and possible selection of mutations related to the resistance of the tested drugs.

This is a clinical trial to evaluate the safety and immunogenicity of R21/MM in healthy Kenyan participants from the different age groups.Participants will receive 3 vaccinations 4 weeks apart.

In Niger, malaria is a major public health problem. It is the main cause of morbidity and mortality among children. The management of malaria cases is based on the principle of early diagnosis and rapid treatment with effective drugs. It is confronted with the appearance of strains resistant to antimalarial drugs, hence the need to monitor antimalarial drug sensitivity. The study was conducted in three regions representing epidemiological strata of the country: Agadez (Centre de santé Intégré of Dagamanet in the Health district of Agadez), Maradi (Centre de santé intégré of Guindaoua in Tessaoua) and Dosso (Centre de santé Intégré centre in Gaya). The protocol used is the WHO standardized protocol of 2009. Artemether/Lumefantrine (AL) was administered with a 28-day follow-up in children aged 3 months to 15 years. A Polymerase Chain Reaction (PCR) correction is planned to differentiate between treatment failure and re-infestation as well as a study of genes responsible for resistance on the main drugs used.

The primary objective is to evaluate the safety of 3 doses given at D0, W4, and W26 of 50 µg dosage of AMA1-DiCo adjuvanted either with GLA-SE or Alhydrogel® in healthy European adults not previously exposed to the parasite P.falciparum and in healthy African adults exposed to the parasite. The safety and the tolerability of the vaccine will be assessed on the rate of solicited and unsolicited events/reactions. The safety profile will include local and systemic reactions/events as well as the biological safety, based on a clinically significant change of the baseline value of the main biological criteria.

Background: Malaria is a cause of substantial morbidity and mortality in Malawi. Prompt and effective treatment of uncomplicated malaria remains a key strategy to reduce the public health burden of malaria. Due to the rising resistance to and falling efficacy of sulfadoxine-pyrimethamine, the first-line treatment of uncomplicated malaria from 1993 to 2007, the National Malaria Control Program (NMCP) revised the national treatment guidelines in 2007. The revised treatment guidelines recommend artemether-lumefantrine as the first-line treatment for uncomplicated malaria and artesunate-amodiaquine as a second-line treatment for uncomplicated malaria. The change in policy was based primarily on efficacy data from other countries in sub-Saharan Africa. However, although both artemether-lumefantrine and artesunate-amodiaquine have been in use in Malawi since 2007, there are relatively few studies assessing their efficacy. In a study conducted in 2004-2006 in Blantyre, artemether-lumefantrine was found to be efficacious.1 In addition, a more recent assessment of artemether-lumefantrine in vivo efficacy conducted in six sites in Malawi in 2009 also suggests that the standard formulation artemether-lumefantrine remains highly efficacious (Kamija Phiri, personal communication). Although, some Malawi-specific data on the in vivo efficacy of the standard formulation of artemether-lumefantrine exists, there are additional data that is needed to support the current policy and inform future policy decisions. In 2010 the NMCP has introduced the dispersible formulation of artemether-lumefantrine (Coartem-D™) for use as a first-line antimalarial in Malawi, due to the global unavailability of the standard formulation of artemether-lumefantrine from Novartis, the key supplier of the standard formulation of artemether-lumefantrine (Coartem™) in Malawi. In light of these developments, an assessment of the efficacy, safety and tolerability of the dispersible formulation of artemether-lumefantrine is warranted. In addition, the efficacy, safety and tolerability of co-formulated artesunate-amodiaquine, the current secondline treatment for uncomplicated malaria, has never been assessed in Malawi and should be evaluated. Lastly, dihydroartemisinin-piperaquine has recently been added to the new World Health Organization (WHO) guidelines for the treatment of uncomplicated malaria. This promising new antimalarial might have a role as a first-line or second-line antimalarial for the treatment of uncomplicated malaria, but there are no efficacy and safety data from Malawi. This knowledge gap needs to be addressed to help inform policy makers about the potential role of dihydroartemisinin-piperaquine for the treatment of uncomplicated malaria in Malawi. Objective: Efficacy and safety of the dispersible formulation of artemether-lumefantrine, co-formulated artesunate-amodiaquine and co-formulated dihydroartemisinin-piperaquine for the treatment of uncomplicated Plasmodium falciparum malaria at Machinga District Hospital- Malawi Methods: An antimalarial drug efficacy trial will be conducted in Malawi. The participants will be febrile people 6-59 months old with confirmed uncomplicated P. falciparum infection. Patients will be sequentially allocated to receive treatment with either the dispersible formulation of artemether-lumefantrine at a dose of 2/12 mg/kg body weight of artemether and lumefantrine, respectively, per dose, given twice a day for 3 days; or co-formulated artesunate-amodiaquine at a dose of 4 mg/kg/day artesunate and 10 mg/kg/day amodiaquine once a day for 3 days; or co-formulated dihydroartemisinin-piperaquine at a dose of 4 mg/kg/day dihydroartemisinin and 18 mg/kg/day piperaquine once a day for 3 days. Clinical and parasitological parameters will be monitored over a 42-day follow-up period to evaluate drug effi¬cacy. The study will be conducted from January to December, 2011. The results of this study will be used to assist the Ministry of Health in Malawi in assessing the current national treatment guidelines for uncomplicated P. falciparum malaria.
