Active clinical trials for "Malaria"

A Phase III randomized controlled multi-centre trial to evaluate the efficacy of the R21/Matrix-M vaccine in African children against clinical malaria

The MiMBa (Malaria in Mothers and Babies) Pregnancy Registry aims to generate robust evidence on the safety of a range of antimalarials when used in pregnancy, particularly in the first trimester. This will be a multi-country observational study and will be deployed in several field sites in Africa.

The RTS, S/AS01E vaccine has been developed for routine immunization of children living in malaria- endemic countries of sub-Saharan Africa. This study is intended as a post-implementation safety study (after vaccine implementation), with the primary objective to evaluate the safety of vaccine after its administration. In addition to the primary objective, the study will also evaluate the impact and effectiveness of the vaccine.

In the REACT 2 project, a consortium proposes to study in Burkina Faso and Côte d'Ivoire, the impact of a public health intervention in rural communities in order to improve access to malaria therapeutic and preventive arsenal for vulnerable populations (i.e. children, adolescents and pregnant women). The intervention relies on the implementation of mobile health workers to support community health workers.

The study is a Phase 2 randomized controlled, partial-blind, parallel group study in plasmodium infected asymptomatic adults 18 years and older, with 8 study arms. It will use the adapted Zelen design, which has two steps in the consent process. In the first step, there is an informed consent from all participants for a cohort lifestyle study. According to this consent, participants are randomized without knowledge about the detailed protocol. In the second step, only participants from the intervention group will receive the information about the intervention and the second consent will be obtained from them. The participants who will decline to participate to an intervention will continue in the cohort study, as the control group.

This study aims to explore whether SMC is an effective intervention in the context of Northen Bahr el Gazal state, South Sudan. It also aims to assess the protective efficacy of the antimalarials used in SMC in the target population and investigate levels of parasite resistance in the study counties. If successful, this trial should provide the evidence for SMC to be included in malaria programming and policy in South Sudan. A Type II hybrid effectiveness-implementation study design will be used to evaluate the effects of a clinical intervention on relevant outcomes whilst collecting information on implementation. It is designed to determine feasibility and effectiveness of an innovative intervention, as well as the protective efficacy of the antimalarial drugs used. The study consists of five components: 1) A series of cross-sectional surveys establishing confirmed malaria cases in children; 2) A prospective cohort study to determine the protective efficacy of SPAQ (if SPAQ provides 28 days of protection from infection) and whether drug concentrations and/or resistance influence the duration of protection; 3) A resistance markers study in children 3-59 months in the research county; 4) Modelling the protective effect of SPAQ in South Sudan to determine where SMC could be a suitable malaria prevention strategy in other areas of the country, and 5) A process evaluation to understand feasibility and acceptability of the SMC intervention in South Sudan.

Malaria remains a major health problem, especially in sub-Saharan Africa where more than 90% of the disease and deaths occur in children. Adding to this high burden among the children is the co-existence of intestinal and genito-urinary worms. Prominent among these are soil-transmitted helminths and schistosomiasis. Existing control programmes for the worms are operating below the expected level, despite the commitments and support that followed the 2012 London Declaration of achieving 75% treatment coverage by 2020. On the other hand, a malaria prevention programme, called Seasonal Malaria Chemoprevention (SMC), introduced in the same year 2012 has achieved more than 75% treatment coverage and prevented 75-85% cases of uncomplicated and severe malaria in children. This encouraging development supports the need to explore the strategies involving the integration of worm control with successful platforms such as SMC. This would align worm and malaria control with the WHO road map for Neglected Tropical Diseases (NTD) of ending the neglect to attain Sustainable Development Goals by eradicating diseases of poverty and promoting health and well-being for those at risk. Given this context, it is important to develop a treatment approach that combines malaria and helminth control in an integrated framework that will be safe, effective and easy to deliver. This study will, therefore, investigate the feasibility and effectiveness of co-administration of anthelminthic and SMC drugs in a high-risk paediatric population living in a malaria-helminth co-endemic setting in Senegal, West Africa. This study is designed to test the hypothesis that co-administration of SMC and anthelminthic drugs will be safe and tolerated among children aged 1-14 years and that the incidence of side effects will not be significant. The objectives of this study are to assess the safety, tolerability, and effects of co-administration of SMC and anthelminthic drugs among the children

This phase 2a open-label study to assess Meplazumab in adult patients diagnosed with Plasmodium falciparum

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 2,080 children in the areas served by 35 health centres in Cameroon. The results of this study will allow direct evaluation of the protective efficacy of PMC on malaria incidence, severe anaemia, and malaria mortality.

The investigators believe that to effectively achieve malaria elimination in Rwanda, it is critical to target the human reservoirs of Plasmodium falciparum using local and readily available Artemisia tea. Asymptomatic infections detectable by PCR are important reservoirs because they often persist for months and harbor gametocytes, the parasite stage infectious to mosquitoes. Lessons learnt from this study will be of critical importance for health decision makers with regard to potential malaria control. MSc and PhD students will be trained and the impact of this research project will be enormous on the socioeconomic transformation of Rwanda.
