Filter by:Significant gains have been made in reducing the overall burden of malaria worldwide, however these have been far greater for Plasmodium falciparum than P. vivax. P. vivax remains a major obstacle to malaria control and elimination efforts, largely due to its ability to form dormant liver stages (hypnozoites) that allows it to escape detection and treatment. Importantly, they are susceptible only to 8 aminoquinolines such as primaquine. However, primaquine is associated with risk of haemolysis in individuals with a genetic condition, called glucose-6-phosphate dehydrogenase (G6PD) deficiency. Additionally, the recommended 14-day prolonged treatment regimen is associated with poor treatment adherence, hence ineffective primaquine treatment. Innovative solutions to the radical cure of both the blood and liver stages of P. vivax are urgently required. The PNG National Department of Health has requested a pragmatic study of the feasibility and cost-effectiveness of implementing point-of-care G6PD testing followed by high-dose, short-course primaquine treatment regimens for patients with P. vivax malaria. This revised case management is to be combined with practicable enhancements to patient education, supervision, malariometric surveillance and pharmacovigilance. This will be a before-after longitudinal health facility-based study implemented at Napapar and Mugil health centres and Baro and Wirui clinics. A staged approach for the implementation of the revised case management strategy will be used, including patient education and counselling, community-based clinical review, with mixed methods evaluation.
The Plus Project will assess the impact, operational feasibility, efficacy, effectiveness, and cost-effectiveness of PMC. Specifically, the impact evaluation will involve monitoring a passive cohort of all children in the study area reporting all doses of SP received and the number of confirmed cases of malaria and anaemia, as well as a prospective active cohort of children who will have seven home visits over an 18-month period. The total number of participants is expected to be approximately 1568 children in the areas served by 19 health centres in Côte d'Ivoire. The results of this study will allow direct evaluation of the protective efficacy of PMC on malaria incidence, severe anaemia, and malaria mortality.
This study aims to confirm the efficacy, safety and tolerability of KLU156, a fixed dose combination of ganaplacide (KAF156) and a solid dispersion formulation of lumefantrine (lumefantrine-SDF), when administered once daily for three days in adults and children ≥ 5 kg body weight and ≥ 2 months of age suffering from uncomplicated P. falciparum malaria (with or without other Plasmodium spp. co-infection). In the Extension phase, the safety, tolerability and efficacy of repeated treatment with KLU156 will be assessed for a maximum of two years in patients who did not experience early treatment failure (ETF), who did not experience any study treatment-related SAE (Serious Adverse Event) previously and who gave informed consent to participate in the Extension phase.
This is a Phase IIb randomised controlled trial of the safety, immunogenicity and efficacy of the blood-stage malaria vaccine candidates RH5.1 in Matrix-MTM and RH5.2-VLP in Matrix-MTM in infants aged 5-17 months in Burkina Faso
In this area of Greater Mekong Subregion (GMS), vivax malaria is the most common kind of malaria. It can stay very long in the liver, and come out later to make another episode of illness. This can happen many times even without a mosquito bite. Only 8-aminoquinoline drugs can kill the liver forms of the malaria parasite. One of these drugs is called primaquine, and it has been used all over the world for a long time. There is now a new formulation of this 8-aminoquinoline drug called tafenoquine that can also treat the malaria in the liver. The main benefit of this drug is that it is a single dose, which makes much convenient for the patients as well as for the malaria control program than conventional 14 days of primaquine. Recent research suggests that ACT (Artemisinin Combination Therapy) may antagonise the efficacy of tafenoquine (Baird et al. 2020 ASTMH Annual Meeting) . This could prevent the use of tafenoquine in areas with chloroquine resistant P. vivax parasites where national malaria programmes recommend ACTs for vivax malaria. Also, currently recommended tafenoquine dose is sub-optimal: 300 mg dose proved significantly inferior to low dose primaquine in a meta-analysis of the phase 3 studies when restricted to the Southeast Asian region (Llanos-Cuentas et al. 2019 NEJM; Watson et al. 2022a Elife). A tafenoquine dose of 450mg is predicted to provide >90% of the maximal effect. The objective of this research is to find out whether 450 mg dose of tafenoquine can be combined effectively with ACT providing a short course treatment for P. vivax malaria.
Two-arm, randomized, double-blinded and controlled clinical trial to first assess the safety and tolerability of the vaccine in a Phase 1b trial and proceed to assess its efficacy against clinical malaria in young children living in highly seasonal malaria areas of Mali
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.
Platform study to evaluate the efficacy and safety of anti-malarial agents in patients with uncomplicated Plasmodium falciparum malaria
This clinical study is a phase 4, single-site, open-label pharmacokinetic (PK) study of IV artesunate in up to 100 Ugandan children 6 months-14 years of age who are diagnosed with severe malaria according to standardized World Health Organization (WHO) criteria (any P. falciparum parasitemia and the presence of danger signs). Participants will receive the standard of care IV artesunate for initial treatment of severe malaria per WHO guidelines: children weighing <20 kg should receive 3.0 mg/kg/dose compared to children weighing =20 kg who should receive 2.4 mg/kg/dose, at times 0, 12, 24, 48 and 72 hours (WHO 2015). Parenteral treatment will be administered for a minimum of 24 hours (irrespective of the patient's ability to tolerate oral medication earlier), after which patients will be evaluated clinically and assessed for ability for oral intake of antimalarials. Children who are able to transition to oral antimalarial therapy will initiate a 3-day course of artemisinin-combination oral therapy per national guidelines. The primary objective of the study is to determine the relationship between DHA exposures following IV artesunate dosing and markers of physiologic dysfunction associated with severe malaria in Ugandan children.
