There are about 69 clinical studies being (or have been) conducted in Gabon. 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.
A randomised, double-blind single-dose (loose combination) study in patients with uncomplicated Plasmodium falciparum malaria. The study will test for efficacy/futility through analyses, using Bayesian methodology. Adults and children will be included through progressive step-down in age following safety analyses. This study investigates the efficacy exposure-response of OZ439/PQP combination in the target populations and if it meets its efficacy objectives, will inform dose setting for Phase III studies.
The objective of this project is to determine clinical and biological predictors of Immune Reconstitution Inflammatory Syndrome (IRIS) occurrence in HIV infected patients who are started on antiretroviral therapy (ART), and to obtain more insight into the pathogenesis of this syndrome. The investigators will prospectively study HIV infected patients in Sub Saharan Africa who will be initiated on ART and are at risk to develop IRIS in all its different appearances. In these patients, the investigators will assess the value of clinical features and plasma biomarkers to predict IRIS, and the investigators will obtain insight into which inflammatory pathways become activated during IRIS. This project will provide novel knowledge about this clinically highly relevant healthcare problem in a resource poor setting, namely in Lambaréné, Gabon, in the Central African rainforest belt. In Gabon little research has been done in the field of HIV. The epidemiological pattern of IRIS in Gabon will be described. Promising putative plasma biomarkers will be validated for their use in daily practice.
Albendazole is a main anti-helminth, however there is a lack of data regarding its efficacy in the school children population. The aim of this study is to evaluate the efficacy of the albendazole one versus two and three doses, in school children infected with intestinal helminth.
The aim of this epidemiology study is to characterize in a standardized way malaria transmission intensity at the clinical trial centers participating in study 110021 (NCT00866619).
Urinary schistosomiasis is a debilitating disease in Central Africa and pregnant women are frequently suffering from this condition. Mefloquine is currently investigated as preventive treatment against malaria in pregnancy and mefloquine is also known to exert activity against schistosomiasis. The investigators want to test the hypothesis whether mefloquine may active against urinary schistosomiasis when used as preventive treatment against malaria in pregnancy.
The purpose of this study is to compare the blood pressure lowering efficacy of a treatment regimen based on a dihydropyridine calcium-channel blocker combined with an angiotensin II type-1 receptor blocker with the recommended treatment regimen based on a low-dose thiazide diuretic combined with a beta-blocker.
The purpose of this observer-blind study is to gather key efficacy, safety, and immunogenicity information on GSK's candidate malaria vaccine in infants and children.
The study aims at comparing the safety, tolerability and efficacy of Mefloquine (MQ) to Sulfadoxine-Pyrimethamine (SP) as Interment Preventive Treatment in pregnancy (IPTp) for the prevention of malaria effects on the mother and her infant.
Patients with non-falciparum infection will be given artemether-lumefantrine for three days and will be followed up for 28 days. Besides efficacy and safety evaluations a substudy on immunology will be performed.
The primary objective is to assess the safety of different doses of ferroquine with artesunate (AS) in adult African patients with uncomplicated malaria. The secondary objectives are to assess activity in reducing parasitemia and the pharmacokinetics of ferroquine and its metabolites.
