There are about 119 clinical studies being (or have been) conducted in Senegal. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Malaria transmission is falling in some parts of Africa as bed nets and anti-malarials become more widely available. However, transmission still persists and it appears that additional control measures are required. The leading malaria vaccine candidate in development is RTS,S which has efficacy against clinical malaria measured at 30-50% in the field. This partial protection might be enhanced by combination with other components. The other vaccination approach that has produced repeatable efficacy in humans is the use of viral vectors to induce T cell responses. Previous attempts with this vaccine approach have been effective in challenge studies in Oxford, but ineffective in the field, probably because of reduced immunogenicity with previous vector platforms. Recently, studies in Oxford, Kenya and the Gambia have shown higher levels of immunogenicity by using a chimpanzee adenovirus (ChAd63) followed by an attenuated vaccinia virus (modified vaccinia Ankara) to deliver the pre-erythrocytic antigen, multiple epitope string with thrombospondin- related adhesion protein (ME-TRAP). The increase in immunogenicity has lead to sterile protection in 3 out of 14 volunteers and partial protection in 5 out of 14 volunteers in challenge studies. The investigators propose a Phase 2b study of 120 healthy adult men in Senegal. The investigators will assess the efficacy and further evaluate the immunogenicity and safety profile of the vaccine regimen. The investigators also intend to assess the correlates of efficacy and natural immunity.
The primary trial objective is to determine the clinically effective dose of orally administered pyronaridine/artesunate (Pyramax®, PA) with a 3:1 ratio to treat adults with acute, symptomatic, uncomplicated P. falciparum malaria in South East Asia and Africa. Secondary trial objectives are to determine the safety of once-daily dosing for 3 days of PA and to explore possible ethnic differences in safety or efficacy.
SchistoVAN aims to study the role of schistosomiasis infection in the modulation of the immune response of children to childhood vaccine antigens, as well as the impact of this infection on their nutritional status and their haemoglobinaemia.
Longitudinal survey in Northern Senegal to investigate the environmental factors modulating the immune response to childhood vaccines and to malaria. A cohort of 410 children aged 1 to 10 from 5 villages of the Senegal River Valley(Podor District) was followed-up for 18 months. During that period, 5 visits have been made to the villages to assess the immunological and nutritional status of the children.
Although the risk of malaria is greatest in early childhood, significant numbers of schoolchildren remain at risk from malaria infection, clinical illness and death. By the time they reach school, many children have already acquired some clinical immunity and the ability to limit parasite growth, and thus most infections are asymptomatic and will go undetected and untreated. Asymptomatic parasitaemia contributes to anaemia, reducing concentration and learning in the classroom, and interventions aiming to reduce asymptomatic parasite carriage may bring education, as well as health, benefits. Intermittent parasite clearance (IPC) delivered through schools is a simple intervention, which can be readily integrated into broader school health programmes, and may usefully supplement the community-distribution of insecticide-treated nets (ITNs) in countries with a policy of universal coverage of nets. This study seeks to establish whether intermittent parasite clearance undertaken once a year at the end of the malaria transmission season can reduce malaria parasite carriage and anaemia amongst school-going children already using insecticide-treated nets, and its consequent impact on school attendance and performance, in order to assess its suitability for inclusion as a standard intervention in school health programmes in areas of seasonal malaria transmission.
Malaria is a major public health problem. 250 million cases annually leads to approximately 1 million deaths. Over 80 per cent of these deaths occur among African children under age five. The main interventions covered treatment with Artemisinin Combination Therapies (ACT), long lasting bednets distribution and Rapid Diagnosis Tests (RDT) to improve malaria diagnosis. This has led in Senegal to a substantial decrease in the incidence of malaria, in 2009. However the recent overall decline hides the fact that malaria incidence remains very high in the south of Senegal. That's why Home-based management (HMM) for malaria is being introduced in selected areas. Intermittent Preventive Treatment (IPT) by monthly administration of a therapeutic dose of antimalarials can achieve a very high degree of protection from attacks of clinical malaria in children. The purpose of this project is to evaluate the effectiveness of combining IPTc with HMM in southern Senegal The study objectives are to : - Assess the tolerance of IPTc using SP+AQ when it is administered for a longer period in areas with a longer transmission season, - Assess the added benefit that IPT with the association of Sulfadoxine-Pyrimethamine + Amodiaquine can offer in populations where a rapid and early care with home management of malaria is already established. - Determine the cost benefit ratio of the addition of IPTc with HMM. A cluster randomized controlled trial has been designed to evaluate the effectiveness of adding seasonal IPTc with sulfadoxine-pyrimethamine plus amodiaquine (SP+AQ) for 5 months per year, in villages where home-based management of malaria is implemented. All villages in Saraya district, excluding 7 villages with a health post, will be eligible to participate. Saraya villages will be combined to form 24 clusters which will be randomized to receive HMM from a community volunteer, or IPTc plus HMM. Trained volunteer Community Medicine Distributors (CMD) will provide HMM. The primary endpoint will be the incidence of clinical malaria with fever or history of fever and parasitaemia with density of at least 3000/ul. Secondary outcomes will include the safety, the tolerability, the coverage and acceptability of the intervention. Both the recurrent and capital costs to the health service of training staff and delivering the interventions will be estimated. Both direct and indirect costs to users of the services (children and their families) will also be assessed.
The aim of the study is to determine the pharmacokinetic profile of sulfadoxine-pyrimethamine plus amodiaquine (SP+AQ) when used for seasonal Intermittent Preventive Treatment (IPT) to prevent malaria in children aged 3 to 59 months in Lamarame, NDoffane District, Senegal. Several studies have shown that seasonal IPT in children can provide a high degree of protection against clinical malaria. SP+AQ is the most effective regimen. However little is known about the pharmacokinetics of amodiaquine and sulfadoxine-pyrimethamine in children. The purpose of this study is to determine the pharmacokinetics profile of SP+AQ when used for IPT in Senegalese children. 150 children aged 3 to 59 months will be enrolled in November. They will receive a therapeutic dose of sulfadoxine-pyrimethamine and amodiaquine, and will be followed up for 30 days. Four finger prick blood samples will be taken from each child for PK analysis.
This is a cross-sectional, epidemiological study to determine the prevalence of cardiovascular risk factors such as obesity, smoking, dyslipidemia, diabetes mellitus and hypertension in patients attending General Practice clinics in the Africa and Middle East region. A total of 4300 patients will be evaluated. In patients who are found to have previously been diagnosed with cardiovascular (CV) risk factors such as dyslipidemia or hypertension, the level of control of their respective conditions will also be evaluated.
This is a phase II, proof of concept, randomized, double-blind, placebo-controlled study to evaluate the protective efficacy against TB disease, safety, and immunogenicity of MVA85A/AERAS-485 in healthy, HIV-infected adults. This study consists of 650 adults subjects (ages 18-50 years of age inclusive) who will receive study vaccine or placebo at Study Day 0 and again 6-9 months later. Samples for real-time evaluation of immunogenicity were to be collected from 70 subjects (immunogenicity analysis set).
The Millennium Villages Project involves the coordinated and simultaneous delivery of a package of proven interventions in health, agriculture, infrastructure and education. The project works in partnership with governments in 10 African countries in areas where progress towards achieving the Millennium Development Goals has been insufficient. The Project evaluation will test the following hypotheses: 1. That after 5 years of operation, villages exposed to the MVP intervention will have a lower rate of under-5 mortality and parallel gains in MDG-related secondary outcomes when compared to similar villages not receiving the intervention. 2. That the coordinated delivery a multi-sector package of health and development interventions implemented through a broad-based local partnership is feasible in a diversity of sub-Saharan African contexts, and; 3. The intervention package can be delivered at a scalable cost of $40 per person per year in the health sector and $110 per person per year in total
