Active clinical trials for "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 trial will evaluate the efficacy of ATSB deployment plus universal coverage of a WHO core vector control (VC) interventions over two transmission seasons on a minimum 30% reduction in cohort clinical disease incidence, confirmed case incidence, and parasite prevalence, as compared with VC alone. Measurement of entomological outcomes, assessment of acceptability and barriers to uptake and consistent use of ATSB, safety and adverse event monitoring and estimation of the cost and cost-effectiveness of ATSB will also occur.

This study assesses the effectiveness of reactive focal mass drug administration (rfMDA), targeting both village and forest working populations, compared to control for reducing the health promotion hospital-level (sub-district) incidence and prevalence of P. falciparum and P. vivax within five provinces in Thailand.

To-date, seasonal malaria chemoprevention (SMC) has only been scaled up across the Sahel region of west and central Africa, primarily because of concerns over widespread resistance to sulfadoxine-pyrimethamine (SP) and amodiaquine (AQ) in east and southern Africa. There are increasing calls for this successful intervention to be used more widely and aggressively, including in areas of east and southern Africa where malaria transmission is seasonal. To test the feasibility, acceptability and impact of SMC with SPAQ in new geographies outside of the Sahel, Malaria Consortium, together with the malaria programmes in Mozambique and Uganda, is conducting implementation studies in both countries. The studies comprise two phases, with the first phase focusing on acceptability and feasibility, followed by more rigorous assessments of the effectiveness of the intervention and chemoprevention efficacy of the medicines used in SMC. Phase 1 of the studies has been successfully completed. The studies showed that SMC with SPAQ was safe, acceptable and feasible, with very high coverage achieved among the target population.Phase 2 of the SMC implementation study in Uganda will include study components exploring the effectiveness of SMC with SPAQ and dihydroartemisinin-piperaquine (DP), as well as the chemoprevention efficacy of DP when used in SMC. The study will be conducted in five districts of Karamoja region. It will involve SMC delivery to around 142,000 children. The majority of the target population will receive SPAQ, but around 15,000 children will receive DP. Five monthly SMC cycles will be implemented between May and September 2022. As the protective period of SPAQ and DP are comparable, monthly administration cycles will be implemented irrespective of the drug regimen used.

This trial aims to characterise the pharmacokinetic (PK) profile and estimate drug exposure of a single oral dose of piperaquine (PQP) in a dispersible granule formulation compared to the PQP hard tablet formulation in the fasted state (Part 1), to advise the selection of dose when the PQP granule formulation is administered in a fed state in healthy adult participants. Part 2 will assess the effect on different types of meal composition on the PK of a single dose of PQP granule formulation in healthy adult participants.

This is an open label, single-site, first-in-human, dose-escalation Phase Ia study to assess safety and immunogenicity of the Plasmodium falciparum malaria vaccine candidate Pfs48/45 in Matrix-M adjuvant in healthy adults living in the UK

This is a household randomized trial of a new tool for house modification, Insecticide-Treated Eave nets (ITENs) in combination with insecticide-treated window screens (ITWS), coated with a dual active ingredient (dual AI): Deltamethrin at 3g AI/kg, which corresponds to 144 mg/m² and PBO synergist at 10g/kg which corresponds to 480 mg/m², as used in the so-called dual-AI LLIN or "resistance breaking" nets for resistance malaria vector control. Four hundred and fifty (450) households with intact walls, opened eaves, and those without screens or nets on the windows in Chalinze district, Tanzania will be eligible and only recruited upon written informed consent. The households will be randomly allocated into two arms: one with ITENs and ITWS installed and the other without. The primary outcome will be malaria parasite detection in household residents aged over 6 months old using a quantitative Polymerase Chain Reaction (qPCR) at approximately 12 months post-installation, coinciding with the long rainy season.

This is a Phase Ib trial conducted in Bougouni, Mali to evaluate the safety and immunogenicity of R21/Matrix-M in a single and two vial presentation, with different immunisation schedules, and when co-administered with EPI vaccines in African children.

This trial will assess the long-term health and socioeconomic impact of interventions targeting low-density malaria infection (LMI) among children in Tanzania

This trial tests the hypothesis that intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) plus dihydroartemisinin-piperaquine (DP) significantly reduces the risk of malaria infection (primary outcome) and adverse birth outcomes (key secondary outcome) in an endemic area of Papua New Guinea (PNG), compared to IPTp with SP alone (the current standard of care). To test this hypothesis a double-blinded, placebo-controlled, phase-III, superiority trial will individually randomize 1,172 HIV-uninfected pregnant women enrolled from 12-26 gestational weeks in equal proportions to one of two IPTp arms: 1) SP given every for weeks, or 2) SP+DP given every 4 weeks. DP placebos will be used to ensure adequate blinding is achieved in the study and follow-up will end 28 days after giving birth.
