There are about 65 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.
Schistosomiasis is a flatworm transmitted from freshwater snails to humans in the tropics. In addition to this infectious disease, tropical developing countries are faced with malnutrition. We propose to alter pesticide and compost use to reduce schistosomiasis and maintain or even improve crop production.
The CADRE study is a multinational observational cohort of patients with sickle-cell disease (SCD) in five west and central sub-Saharan African countries. The aim of this project is to describe the incidence and assess the predictive factors of SCD-related micro- and macro-vascular complications in sub-Saharan Africa.
STUDY OBJECTIVE To confirm the incidence of in-hospital postoperative complications in adult surgical patients in Africa. STUDY DESIGN Seven day, African national multi-centre prospective observational cohort study of adult (≥18 years) patients undergoing surgery. Patients will be followed up for a maximum of 30 days. We will follow the original International Surgical Outcomes Study (ISOS) study design. The primary outcome is in-hospital postoperative complications in adult surgical patients in Africa. Secondary outcomes include in-hospital mortality and the relationship between postoperative complications and postoperative mortality. The intention is to present a representative sample of surgical outcomes across all African countries. This study will run between February and March 2016.
The clinical trial phase 2a is designed to assess the safety of the active ingredient (protein + adjuvant) and secondarily its immunogenicity in healthy male adults from 18 to 49 years of age with a history of infection with intestinal and urinary schistosomiasis, living in the Valley of the Senegal River, a highly endemic area for schistosomiasis. Two arms in the study will test different doses of GLA-SE adjuvant (2.5 and 5 μg). This phase IIA in adults is considered to be a preliminary step in safety before starting trials in children in endemic areas to S. mansoni or S. haematobium, target population of the vaccine.
This study is a prospective, systematic evaluation to assess the effectiveness and safety of introduction of UBT into PPH care at secondary level and district hospitals in 3 low-resource countries. The first component of the evaluation is a prospective stepped wedge cluster randomized design to assess the potential reduction in PPH-related mortality and invasive procedures (blood transfusion, arterial ligation, hysterectomy and uterine arterial embolization) for PPH performed at participating facilities following introduction of UBT. The second component is a nested cohort analysis to assess the safety and acceptability of UBT among women diagnosed with PPH.
This study is a randomized, double-blind, placebo controlled trial that will enroll 250 women (125 per study arm). The objective of the study is to determine the efficacy and tolerability of oral tranexamic acid when used as an adjunct to misoprostol for treatment of postpartum hemorrhage (PPH). Women will be diagnosed with postpartum hemorrhage if blood loss reaches 700ml in the calibrated receptacle. If diagnosed with postpartum hemorrhage , the woman will be randomized to receive either tranexamic acid or placebo, both in tablet form. All participants will receive 800 mcg sublingual misoprostol (4 tablets 200mcg each). The investigators hypothesize that tranexamic acid (in tablet form) as an adjunct to misoprostol will be more effective than misoprostol alone in stopping postpartum bleeding without recourse to further treatment in significantly more women.
The purpose of this study is to assess the safety and reactogenicity of a single IM dose of the ChAd3 EBO-Z vaccine, overall and in children aged 1 to 5, 6 to 12, and 13 to 17 years, separately Considering the risk of exposure to Ebola and the potential (based on animal data) for the investigational ChAd3-EBO-Z vaccine to afford at least partial protection, all children in the study will receive the investigational ChAd3 EBO-Z vaccine. The children in the Group EBO-Z/ MENACWY-TT will receive the investigational ChAd3-EBO-Z vaccine at Day 0 of the study, whereas the children in the Group MENACWY-TT/ EBO-Z will receive Nimenrix at Day 0 (as a control). At Month 6, the children in the Group MENACWY-TT/ EBO-Z will receive the investigational ChAd3-EBO-Z vaccine (provided that no safety concerns are raised), whereas the children in the Group EBO-Z/ MENACWY-TT will receive Nimenrix..
The work will be conducted in six health posts in the regions of Matam (Kanel and Ranérou districts) and Louga (Linguère district), that were selected in 2014 on the basis of the malaria incidence rate, the heterogeneity of transmission between villages in the health post catchment areas, their proximity, and the availability of historical data from before 2014. Malaria elimination strategies were already implemented in the same health posts in 2014 and are still ongoing, thus this protocol aims to strengthen these activities. Seven health posts with similar characteristics but with a slightly lower incidence rate were chosen as controls. It will be implemented in all villages in the six intervention health posts and it will consist of investigating all passively detected cases (index cases) and conducting focal test and focal drug administration (FT/FDA) with dihydroartemisinin-piperaquine (DHAP) in all index case and neighboring households with a positive RDT. All household members in households with a positive RDT will be treated, regardless of their RDT results. Impact of the enhanced Step D on malaria incidence and prevalence will be evaluated using before-after comparison and compared to the change in the control health posts and the operational aspects will be assessed for subsequent scale up.
This is a clinical trial in which healthy volunteers will be administered two experimental Ebola vaccines: ChAd3-EBO Z and MVA-EBO Z. Two groups of volunteers will be vaccinated with both vaccines one after the other in a prime/boost regimen. All ChAd3-EBO Z doses are 2.5 x 10^10 - 3.7 x 10^10 vp and all MVA-EBO Z doses are 1.0 x 10^8 pfu. All volunteers will receive a ChAd3-EBO Z priming vaccine and a MVA-EBO Z boosting vaccine 7 days later. The site of administration of the MVA-EBO Z vaccine differs between the two groups: Group 1 will receive the MVA-EBO Z vaccine in the same arm as the ChAd3-EBO Z vaccine. Group 2 will receive the MVA-EBO Z vaccine in the opposite arm from the ChAd3-EBO Z vaccine. The study will assess the safety of the vaccinations, and the immune responses to vaccination. Immune responses are measured by tests on blood samples. The ChAd3-EBO Z and MVA-EBO Z vaccines are called viral vectored vaccines. They are made from viruses which are modified so that they cannot multiply. The viruses have extra DNA in them so that after injection, the body makes Ebola proteins (but Ebola does not develop), so that the immune system builds a response to Ebola without having been infected by it. Healthy volunteers will be recruited in Dakar, Senegal. The study will be funded by GSK.
The purpose of this study is to assess the safety and immunogenicity of the investigational ChAd3-EBO-Z vaccine administered to approximately 3 000 adults in Africa as a single IM dose Considering the risk of exposure to Ebola and the potential (based on animal data) for the investigational ChAd3-EBO-Z vaccine to afford at least partial protection, all subjects in the study will receive the investigational ChAd3-EBO-Z vaccine. The subjects in the Group EBO-Z will receive the vaccine at Day 0 of the study, whereas the subjects in the Group Placebo/ EBO-Z will receive a placebo at Day 0 (as a control) and will receive the investigational ChAd3-EBO-Z vaccine at Month 6, provided that no safety concerns are raised. In addition, vaccinating all subjects in the study with the investigational ChAd3 EBO Z vaccine will allow an increase of the safety database of the investigational vaccine. In case the geographic range of Ebola virus Zaire (EBOV) transmission expands to encompass any of the regions where this trial is conducted, earlier administration of the investigational ChAd3-EBO-Z vaccine to the subjects in the Group Placebo/ EBO-Z will be considered in that region.
