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.
This study will provide the Senegal Ministry of Health with data on the safety and immunogenicity of adjuvanted trivalent inactivated influenza vaccine (adjTIV) and full-dose seasonal non-adjuvanted trivalent inactivated influenza vaccine (TIV) in children. This data will inform future policy considerations for influenza vaccine. The study is not powered to detect significant differences between vaccines or groups, and no hypotheses are to be tested; therefore, immunogenicity and safety objectives are to be analyzed descriptively.
The advent of highly active antiretroviral treatment has resulted in the survival into adolescence of an increasing proportion of infants and children with perinatal HIV infection in Senegal. However, the transformation of HIV into a chronic disease needing lifelong antiretroviral treatment (ART) raises new challenges, among others related to a disturbance of glucose metabolism, lipid abnormalities, in addition to the potential effects on children's growth and puberty. Little is known on nutritional and metabolic changes in HIV-infected children on ART in Africa, while implementation of the latest WHO recommendations should eventually lead to an increase in the number of children on ART in this region. Moreover, bio-clinical evolution of untreated children is poorly documented in the African context. It therefore urgently needed to institute a cohort study to evaluate, in the long term, the impact of HIV infection and/or ART on nutritional and metabolic disorders and to characterize the risk factors of their occurrence in children and adolescents infected as they move through adolescent into adulthood.
This is a large, community-based, cluster-randomized trial to compare routine prophylactic use of 600 mcg oral misoprostol and 10 IU oxytocin delivered by UnijectTM intramuscularly during the third stage of labor
The purpose of this study is to demonstrate noninferiority (a new treatment is equivalent to standard treatment) in terms of the percentage of patients who have plasma human immunodeficiency virus-type 1 (HIV-1) ribonucleic acid (RNA) levels less than 400 copies per mL after 48 weeks of randomized treatment with tenofovir disoproxil fumarate/emtricitabine/rilpivirine (TDF/FTC/RPV) versus TDF/FTC/efavirenz (TDF/FTC/EFV).
This is an observational study to assess the experience of current depot medroxyprogesterone acetate (DMPA) intramuscular (IM) clients and providers when they try Depo-subQ in Uniject and offer recommendations for the introduction of this method.
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.
