There are about 43 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.
FEVRIER study is an observatory of hospitalizations in cardiology units in sub-Saharan Africa.
The study is to be performed in public health facilities in Central and West Africa where Pyramax will be used as treatment of uncomplicated malaria episodes, including repeat episodes. The study is to assess the safety of Pyramax, particularly in patients with underlying liver function abnormalities, in patients who have co-morbid conditions, such as HIV, and also in very small children (<1 year of age).
This study aims to determine the most effective and tolerable dose at the shortest dosing regimen of the investigational drug KAF156 in combination with a solid dispersion formulation of lumefantrine (LUM-SDF) in adult/adolescent and pediatric patients with uncomplicated P. falciparum malaria. There is unmet medical need for anti-malarial treatment with new mechanism of action to reduce probability of developing resistance, and for duration shorter than 3 days of treatment and/or reduced pill burden.
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.
The principal objective is to evaluate a cure rate and number of adverse events of with confirmed multidrug-resistant tuberculosis patient treated with a 9months regimen.
Double blind, randomized, controlled, dose-escalation Phase 1 clinical trial in hookworm-exposed children aged 6 to 10 years living in the area of Lambaréné, Gabon. Children will receive three doses of the Na-GST-1/Alhydrogel hookworm vaccine co-administered with the Na-APR-1 (M74)/Alhydrogel hookworm vaccine or the hepatitis B vaccine co-administered with sterile saline. All injections will be delivered intramuscularly (deltoid) on approximately Days 0, 56, and 112 or 180.
Assessing the effect of neglected tropical diseases on Plasmodium falciparum transmission in an area of co endemicity.
This study will evaluate the efficacy of a fixed dose combination (FDC) containing bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus dolutegravir (DTG) + a FDC containing emtricitabine/tenofovir alafenamide (F/TAF) in HIV-1 infected, antiretroviral treatment-naive adults at Week 48.
Malaria is a protozoan infection transmitted by anopheline mosquitoes. The most severe forms are caused by Plasmodium (P) falciparum and to a much lesser extent by P. vivax. Although the interest in research on malaria has increased during the last years, yet little research is conducted on the "neglected" malaria species P. ovale and P. malariae. P. ovale being first described in 1922, it still remains unclear whether it displays dormant pre-erythrocytic liver stages, so called hypnozoites, or not. Primaquine, the only marketed drug with liver stage activity at present, can cause severe hemolysis in glucose-6-phosphate dehydrogenase (G6PD) deficient persons and methemoglobinemia. Because G6PD is widely spread in Central Africa, it is important to explore whether additional intake of liver-active medication is really needed and on this account further research to investigating new treatment options with liver stage activity should be conducted. While, due to widespread resistance, treatment recommendations for P. falciparum and mixed infections have switched from chloroquine to the safer applicable artemisinin-based combination therapies (ACTs), World Health Organization (WHO) guidelines still suggest chloroquine as first line treatment for P. malariae and P. ovale mono infections. Further studies assessing alternative treatment options are largely missing. Summing up the current situation for both topics shows the need for further research. Therefore this study aims to assess the evidence and characterize the frequency of relapses in P. ovale infections with respect to differences between its subspecies as well as the effectiveness of the ACT artemether-lumefantrine in P. malariae and P. ovale mono- and mixed infections.
Primary Objective: To determine whether a single dose combination of OZ439 (Artefenomel)/FQ (Ferroquine) is an efficacious treatment for uncomplicated Plasmodium falciparum malaria in adults and children. Secondary Objectives: To evaluate the efficacy of OZ439 (Artefenomel)/FQ (Ferroquine): - To determine the incidence of recrudescence and re-infection. - To determine the time to relief of fever and parasite clearance. To evaluate the safety and tolerability of OZ439 (Artefenomel)/FQ (Ferroquine). To evaluate the pharmacokinetics of OZ439 (Artefenomel)/FQ (Ferroquine). To explore in vitro drug resistance of P. falciparum infecting patients >14 years old in Vietnamese sites.
