Filter by:This registry will assess pregnancy outcomes through demographic surveillance and prospective data collection at a health facility in Kalifabougou, Mali.
The purpose of this study is to assess the safety, tolerability, and pharmacokinetics of L9LS in infants in Mali and to evaluate the impact of L9LS on subsequent R21/Matrix-MTM vaccine immunogenicity.
Across sub-Saharan Africa, school-age children bear an under-appreciated burden of malaria. An estimated 200 million school-age children are at risk of malaria and in many areas prevalence of infection exceeds 50%. The high infection rates in this group serves as a source of onward parasite transmission, undermining elimination and control efforts. Furthermore, malaria illness and malaria-induced anemia in this age group lead to school absenteeism, and impaired cognitive function and classroom attention, ultimately resulting in reduced academic achievement. Although universal malaria interventions, such as insecticide treated nets (ITNs) and access to prompt diagnosis and treatment are available to school-age children, this age group is the least likely to benefit from these interventions. Furthermore, efficacy of these approaches may be compromised by increasing anti-malarial drug and insecticide resistance. A malaria vaccine could help to avert the burden of malaria in this age group. The RTS,S/AS01 malaria vaccine has recently been recommended for vaccination of young children (< 24 months) by the World health organization (WHO) after a Phase 3 trial and an implementation trial showed that the vaccine had moderate but significant efficacy to prevent clinical and severe malaria in young children. Previous randomized trials suggest that the vaccine is safe for older children. However, efficacy of the vaccine has never been assessed in school age children. Kamuzu University of Health Sciences in partnership with the Malawian Ministry of Health seeks to evaluate the efficacy of the newly introduced RTSS/AS01 malaria vaccine in school aged children. The study hypothesizes that vaccination will decrease the morbidity and transmission of malaria, as well as improve school absenteeism and educational outcomes.
Mali faces a significant challenge with malaria, particularly among its younger population. While existing measures like seasonal chemoprevention and vaccination have shown efficacy, further innovations are necessary to combat this disease. The monoclonal antibody TB31F shows promise in reducing the transmission of malaria. This clinical trial will evaluate the safety and efficacy of the monoclonal antibody TB31F.
This study will test a new drug (MAM01) to find which doses are safe and could help prevent people from getting malaria. The study will take place in parts of Africa where malaria is common. Parts A and B of the study will first test single doses of MAM01 in healthy adults, then after safety review, in older children, and then after additional safety review, in infants. Part C will then test single doses of MAM01 in children and infants who have a medical problem that could put them at greater risk if they get malaria.
Plasmodium vivax has become the predominant species in the Greater Mekong Subregion and is a major challenge for regional malaria elimination. Mass primaquine administration has played a decisive role in malaria elimination in many temperate zone countries, but its efficacy in tropical areas remains to be evaluated. This study aims to assess the efficacy of targeted primaquine mass treatment (TPT) for eliminating P. vivax malaria in northern Myanmar.
Malaria is still a leading public health concern in Myanmar. However, people living in rural areas usually showed poor prevention practice despite residing in malaria hotspots. The majority in Myanmar are Buddhists who frequently visit the monastery and receive the speech delivered by the monks. In a malaria high burden township of the Sagaing Region from northern Myanmar, current study will first explore the difference in malaria preventive practices among people residing in different malaria-endemic villages through a mixed-methods approach. Next, this research will address the knowledge gaps by a monastery-based health education delivered by trained Buddhist monks using standardized health messages instruction for six consecutive months between August 2022 to January 2023. To test whether the intervention could balance those gaps among different groups, quantitative data of baseline, 3-month, and 6-month will be compared using descriptive statistics, chi-square test, T-test or repeated ANOVA, and the Difference-In-Differences (DID) analysis, as applicable.
A prospective study will be carried out in an area where parasites with reduced sensitivity to malaria drugs (artemisinins) have recently emerged. The study will recruit participants from patients who attend the clinic with uncomplicated malaria and are treated with conventional artemisinin-combination therapies (ACT) as part of standard clinical care. From this population, we will select P. falciparum gametocyte carriers. Before, during and after ACT treatment, the transmission potential of artemisinin resistant and wild type infections will be assessed by microscopy, molecular methods, parasite culture and mosquito feeding assays. Parasite clearance will be determined in the first days (d0-3) after treatment. The study population will consist of passively recruited patients with uncomplicated P. falciparum malaria who are microscopy positive for gametocytes. Participants will be treated with conventional therapies for uncomplicated malaria without randomization: artemether-lumefantrine (AL) or dihydroartemisinin-piperaquine (DHA-PPQ). All doses are supervised. Parasite clearance is assessed ex vivo by ring-stage survival assays and by daily slides during the first days of treatment. Gametocyte carriage and gametocyte commitment/production will be determined for resistant and wild type infections before, during and after treatment. In addition, venous blood will be collected at three timepoints to assess transmission to mosquitoes before (d0), during (d2) and after treatment (d7). The total duration of participation will be 7 days, the primary endpoint will be the reduction in mosquito infection rates at d2 (artemether-lumefantrine) or d7 (dihydroartemisinin-piperaquine) compared to pre-treatment.
Seasonal malaria chemoprevention (SMC) is a highly effective community-based intervention to prevent malaria infections caused by Plasmodium falciparum in areas where the burden of malaria is high and malaria transmission is seasonal. SMC is commonly seen as a success story in the Sahel region, however, there are regions in east and southern Africa where malaria transmission is seasonal, and the burden is high. However, the same decision-making frameworks that was used in the Sahel are unlikely to be applicable to east and southern Africa due to higher pre-existing resistance to the drugs used, seasonality heterogeneity, contextual difference, and unknown cost-effectiveness, amongst others. This study aims to estimate the chemoprevention efficacy, potential upscale impact, acceptability, and feasibility of SMC with sulfadoxine-pyrimenthamine + amodiaquine (SP+AQ) medicines in Niassa Province in Mozambique. The study is divided into two separate components with different objectives which outputs feed into each other: a non-randomized controlled trial to estimate the chemoprevention efficacy of SP+AQ; and a qualitative study that will evaluate the feasibility and acceptability of the intervention. These will be the first studies analysing the chemoprevention efficacy, feasibility, acceptability, and potential scale-up impact of SMC in Niassa Province, Mozambique The outcomes of these studies aim to guide future policy changes at local, national, and international levels and potentially allow for a historically successful program to expand in a sustained and cost-effective way beyond the Sahel region.
The purpose of the study is to investigate the impact of the eCHIS intervention on key child health outcomes.
