Severe Malaria in Remote Areas- Closing the Evidence Gap

The goal of this observational study is to assess whether the giving of rectal artesunate and a three day course of an Artemisinin based Combination Therapy (ACT) to children aged 6 months and ≤ 5 years with severe malaria when referral is not feasible is non inferior to giving of injectable artesunate and three day course of an ACT. The three primary objectives are: * To evaluate the 28-day PCR corrected cure rate in children aged 6 months to ≤ 5 years treated with RAS+ACT or RAS+injectable artesunate, assessing whether each treatment achieves the clinically acceptable cure rate of 97% ± 5%. * To evaluate feasibility of provision of rapid treatment of severe malaria with rectal artesunate in children 6 months to ≤ 5 years not able to access a referral health facility, by a community health worker or in health facility where there is no injectable artesunate available. * To evaluate the impact of reinforcing the integrated Community Case Management (iCCM) on access to the formal health care system The study is being done in Nchelenge district in Zambia and Kapolowe district in the Democratic Republic of Congo. It will enrol 1008 children with severe malaria and an equal number of children with simple malaria

PDMC Implementation Trial in Kenya

The goal of this implementation trial is to evaluate at least two alternative delivery strategies and adherence support for malaria chemoprevention with dihydroartemisinin-piperaquine in the post-discharge management of children hospitalised with severe anaemia or severe malaria to optimise adherence in Kenya. The actual interventions to be evaluated have been co-designed with national stakeholders during an initial formative research stage.

Platelet-Directed Whole Blood Transfusion Strategy for Malaria

Open-label randomized controlled trial to test the effectiveness of whole blood transfusion for improving survival in children with severe malaria complicated by thrombocytopenia.

Monoclonal Antibodies in Children With Severe Anaemia or Severe Malaria to Prevent Malaria After Hospital Discharge

Background and rationale: Hospitalised children with severe anaemia remain at high risk of dying or requiring hospital readmission for at least 6 months after discharge. In highly malaria-endemic settings, malaria is a major contributor to these post-discharge readmissions and deaths. In 2022, the World Health Organisation (WHO) recommended post-discharge malaria chemoprevention (PDMC) for children hospitalised with severe anaemia living in malarious areas. Kenya, together with several other countries in sub-Saharan Africa, aims to expand WHO's recommendation and introduce PDMC in children hospitalised with severe anaemia or severe malaria, including children with severe malaria who do not have severe anaemia (e.g. cerebral malaria). PDMC consists of full 3-day treatment courses with long-acting antimalarials given monthly three times after discharge. PDMC is very effective in clinical trials. However, adherence to these monthly 3-day drug treatments is limited under real-life conditions. Furthermore, PDMC provides chemoprevention for about 3.5 months only, while the risk of dying or needing to be readmitted remains high for several more months. The US National Institutes of Health (NIH) has developed two monoclonal antibodies targeting Plasmodium falciparum malaria (mMAb). These proteins specifically target a highly conserved epitope found on the circumsporozoite protein-1 (CSP-1) of P. falciparum to neutralize it and prevent malaria infection. A key feature of mMAbs is that they can provide protection for up to 6 months with a single dose and thus serve as a "long-acting" drug. Recent placebo-controlled studies in healthy adults in Mali suggest that the first mMAb, CIS43LS, when administered at a dose of 40 mg/kg intravenously (IV), can block 88% of malaria infections for at least 6 months. More recently, studies with a newer mMAb called L9LS, which is anticipated to be more potent than CIS43LS, showed a 74% reduction in uncomplicated clinical malaria by 6 months when administered subcutaneously to healthy Malian children aged 6-10 years by a single subcutaneous (SC) dose of 10-20 mg/kg (NCT05304611). Similar studies with L9LS are ongoing in healthy children under 5 years of age in Siaya, western Kenya (NCT05400655). Young children admitted to hospitals in highly malaria-endemic areas with severe anaemia or severe malaria are an ideal target group for passive immunoprevention with mMAbs as a single infusion with mMAb while in the hospital could protect this high-risk group during the entire vulnerable post-discharge period. Overview design: investigators will conduct a 2-arm, multi-centre, individually randomised, placebo-controlled non-inferiority trial in 398 children with severe malaria or severe anaemia. Children will be randomly assigned (1:1) using minimum sufficient balance (MSB) randomisation to receive either mMAb before discharge or 3 courses of monthly PDMC after discharge, according to WHO guidelines. The study will be placebo-controlled. Children in the PDMC arm will receive a placebo infusion with normal saline before discharge; children in the mMAb arm will receive placebo-PDMC. All children will receive standard in-hospital care, including a blood transfusion and treatment for severe malaria where indicated. They will also receive a full 3-day treatment course with the antimalarial artemether-lumefantrine (AL) to clear any existing malaria infections as soon as they have recovered and can take oral medication. The primary endpoint is the incidence of clinical malaria detected by passive case detection by 6 months post-discharge (the intervention period). Key secondary endpoints include the rates of readmissions and deaths (all children). Children will be followed for another 6 months (post-intervention period) to determine the duration of protection, any long-term impact (e.g., growth) and if mMAbs result in a delayed acquisition of natural protective immunity against clinical malaria Study Interventions: All children will receive standard in-hospital care, including a blood transfusion, antibiotics, and treatment for severe malaria where indicated. All children in both arms will be empirically treated for malaria infection around discharge with a 3-day regimen with artemether-lumefantrine to ensure parasite clearance of any existing parasites. Participants in the mMAb arm will receive the study agent L9LS IV with a target dose of 30 mg/kg. The IV dose will use 1 kg step increases. During the 6-month intervention period, children in the placebo-mMAbs arm will receive three courses of monthly PDMC as per WHO guidelines with dihydroartemisinin-piperaquine (DP) at 2, 6 and 10 weeks post-discharge. Those in the mMAbs arm will receive an identical placebo PDMC

Post-discharge Malaria Chemoprevention Implementation Trial in Benin

The proposed research aims to conduct implementation trials in Benin, co-designed with national stakeholders, to evaluate different delivery strategies for optimizing health system delivery of post-discharge malaria chemoprevention (PDMC) drugs and adherence to PDMC. This chemoprevention strategy is effective in reducing hospital readmissions and deaths after discharge. However, there is no clear delivery platform for PDMC, and adherence to the 3-day dosing regimen, provided monthly three times after discharge, is a potential limitation. The current trial will provide evidence-based data on acceptability, feasibility, and cost-effectiveness to aid decision-makers. The evidence generated will be used to support the effective implementation and scale-up of PDMC in high malaria-endemic areas such as Benin.

Enhancing Pediatric Acute Care Through Adaptive E-Learning and In-Person Skills Practice in Tanzania

The goal of this clinical trial is to evaluate whether the integration of in-person skills practice (ISP) with an adaptive e-learning platform can improve refresher learning progress (RLP) among healthcare providers in pediatric care settings in Tanzania. The main questions it aims to answer are: Can healthcare providers who participate in ISP sessions facilitated by clinical champions achieve greater improvements in refresher learning progress (RLP)? Will providers in the intervention group demonstrate improved metacognition and practical skill performance compared to those in the control group? Researchers will compare healthcare providers using the ISP digital platform (Rhapsode Capable™) to providers using paper-based ISP to see if the digital platform results in significantly higher RLP and fewer skill-based errors. Participants will: Complete adaptive e-learning modules focused on pediatric care topics (e.g., newborn resuscitation, severe malnutrition). Participate in ISP sessions where clinical champions provide feedback and assess performance.
