Filter by:Study Population: Participants of the previous PRIMVAC vaccine trial and women aged 18 to 35 years Sample Size: 90 Study duration: 21 months Subject duration: 12 months if pregnancy doesn't occurred. In case of pregnancy, the participant will be followed up until the delivery. Study Design: Long term observational study comparing the immunology trend of 3 groups of i) women who received the PRIMVAC Vaccine or Placebo during the phase 1b trial in Burkina Faso; ii) women of the same age and nulligravid who did not participate in the phase 1b trial iii) women of the same age and primigravid who did not participate in the phase 1b trial Co Primary objectives - To assess the dynamics of humoral immune response to the vaccine antigen during long term follow up of the study participants - To evaluate the functional durability of the humoral immune responses of women who participated in the phase 1b vaccine trial compared to women of the same age Secondary objectives - To assess the cellular immune response during the follow-up period - To assess the incidence of clinical malaria on study participants - To assess the prevalence of Placental Malaria in study participants and adverse outcomes such as maternal anemia, low birth weight, stillbirth and prematurity.
The scientific objective of this study is to test the protective effect of permethrin-treated lesus against P. falciparum malaria in infants and young children.
A Phase Ib trial to evaluate the safety and immunogenicity of R21/Matrix-M™ in African children living with HIV
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 is a classical in vivo clinical trial, following World Health organization's recommendations, ran as a multisite study within Mozambique trying to assess the efficacy and safety in 5 sites of the four oral ACTS artemether-lumefantrine (AL), Amodiaquine-Artesunate (AQ-AS), Dihydroartemisinin-Piperaquine (DHP) and Pironaridine-Artesunate for the treatment of uncomplicated malaria in children aged<5 years.
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.
The purpose of this study is to evaluate the safety and tolerability of onetime subcutaneous (SC) or intravenous (IV) administration of monoclonal antibody (MAb) L9LS in healthy Malian adults and one-time SC administration of L9LS in healthy Malian children, as well as its protective efficacy against naturally occurring Plasmodium falciparum (Pf) infection over a 7-month malaria season in healthy Malian children 6-10 years of age.
This is an open-label, single-centre, non-randomised, first-in-human Phase Ia study to assess the safety and immunogenicity of the Pvs25-IMX313 vaccine, administered in Matrix-M1 adjuvant.
First-in-Human, Randomised, Dose-Finding Single Center Study to evaluate three dose levels of a novel malaria vaccine, MSP3-CRM-Vac4All/ Alhydrogel® : 3 µg, 10 µg and 30 µg
We describe a Type II hybrid effectiveness-implementation study design which evaluates 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 drugs used. The study consists of three components: 1) Conducting a cluster randomized controlled trial (cRCT) through household surveys establishing confirmed malaria cases in children; 2) Conducting a prospective cohort study to determine the chemoprevention efficacy of sulfadoxine-pyrimethamine and amodiaquine (SPAQ) and whether drug concentrations or parasite resistance influence the duration of protection; and 3) Conducting a resistance markers study in children 3-59 months to measure changes in resistance marker prevalence over time.
