There are about 23 clinical studies being (or have been) conducted in Guinea. 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.
The purpose of this study is to assess the safety and reactogenicity of a heterologous 2-dose regimen utilizing Ad26.ZEBOV (first vaccination; Dose 1) and MVA-BN-Filo (second vaccination; Dose 2) administered intramuscularly (IM) on Days 1 and 57, respectively.
Principal objective Assess the operational efficacy of a strategy combining early diagnosis and preventive antiretroviral treatment systematically reinforced from the birth* among infants at high risk of infection with HIV** . - in a maximum of 48 hours after delivery - born from HIV infected mothers who received less than 4 weeks of antiretroviral therapy prior delivery and / or HIV infection diagnosed at delivery Intervention, a combined strategy : After positive HIV infection screening from mother in the delivery room and put on antiretroviral treatment of mothers with post partum according to national guidelines , newborns benefit : - Early detection of HIV infection at birth - Without awaiting the outcome of early detection result, a preventive reinforced antiretroviral treatment (zidovudine, lamivudine, nevirapine or zidovudine, lamivudine if their mother is infected with HIV-2), from birth for 12 weeks. - Regular HIV screening until the end of breastfeeding or later to 18 months. - In case of positive results of an HIV test, an antiretroviral treatment with zidovudine, lamivudine, lopinavir, ritonavir whatever serology HIV 1 or 2.
The study determines the diagnostic performance and cost of rapid diagnostic tests (RDTs) performed on human African trypanosomiasis clinical suspects in peripheral health centres, whether or not followed by serological and/or molecular tests on dried blood spots done at regional reference centres
Recent advances in molecular diagnostics of tuberculosis, especially the GeneXpert Mycobacterium tuberculosis/Rifampicin test have reduced the time to diagnose Rifampicin Resistant Tuberculosis (RR-TB) but only rifampicin resistance is diagnosed, leading to presumptive diagnosis of resistance to isoniazid and maybe other drugs. Thus in low and middle income countries, most drug sensitivity testing relies on phenotypic drug resistance testing, which takes up to 4 months. In addition, currently, culture on monthly sputum samples is recommended by the World Health Organization for follow-up of Rifampicin Resistant Tuberculosis patients under treatment. Unfortunately, culture is often not locally available and samples need to be transported from field to culture laboratories. The associated transport delays lead to high rates of contamination and false negative culture, particularly in laboratories in low resource settings. Many gaps for the diagnosis and management of RR-TB patients still need to be addressed and the DIAMA project (DIAgnostics for Multidrug resistant tuberculosis in Africa) study aims to address some of them.
FEVRIER study is an observatory of hospitalizations in cardiology units in sub-Saharan Africa.
The goal of this study is to assess efficacy and safety of SCYX-7158 given as a single dose oral treatment for adult patients (above or equal 15) in the fasting state with T.b. Gambiense HAT
The purpose of this study is to evaluate immunogenicity, epidemiological efficacy and safety of medicinal product GamEvac-Combi - Combined Vector-Based Vaccine against Ebola Virus Disease, 0.5 ml+0.5 ml/dose
This study evaluates the effectiveness of fexinidazole administered to patients with g-HAT at all stages of the disease. The aim of the present study is to provide additional information on the effectiveness and safety of fexinidazole and to assess its use under conditions as close as possible to those in real life, both in patients treated on an out-patient basis and in the hospital setting, depending on clinical status
D²EFT is a randomised, open-label study in HIV-1 infected patients failing first-line antiretroviral therapy (ART). The study compares 2 regimens of second-line ART (dolutegravir and darunavir pharmaco-enhanced with ritonavir and dolutegravir and 2 prespecified NRTIs) with the WHO recommended regimen of 2NRTIs plus a ritonavir-boosted PI (Standard of Care (SOC)). 1,010 participants from 14 predominantly low-middle income countries will be followed for 96 weeks with the primary endpoint at week 48. The design is based on the hypothesis that one or both of the new regimens will be non-inferior to SOC in terms of virologic control while being easier to take, economically viable and affording simplification of treatment programs.
The purpose of this study is to evaluate the safety and immunogenicity of three vaccine strategies that may prevent Ebola virus disease (EVD) events in children and adults. Participants will receive either the Ad26.ZEBOV (rHAd26) vaccine with a MVA-BN-Filo (MVA) boost, or the rVSVΔG-ZEBOV-GP (rVSV) vaccine with or without boosting, or placebo.
