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.
The purpose of this study is to Understand the natural history of Coronavirus 2019 (COVID-19) infection to better define the period of infectiousness and transmissibility and to establish biobanks of COVID-19 blood and mucosal samples.
The purpose of this study is to identify the safe and effective dose of intravenous cipargamin in participants with moderately severe and severe malaria. The study also intends to evaluate clinical treatment success using a novel clinical endpoint for drug development in severe malaria. Severe malaria is a medical emergency and is affecting primarily young children in Africa. Injectable artesunate is the standard of care for the treatment of severe malaria and is highly efficacious. However, the spread of artemisinin-resistance in Plasmodium falciparum in Asian countries poses a threat for future treatment of patients with this life-threatening disease. To mitigate this risk, there is a need of another drug in malaria endemic countries. Cipargamin treatment results in rapid clearance of parasites including artemisinin resistant parasites.
This study aims to determine the efficacy, safety and tolerability of the investigational drug KAF156 in combination with a solid dispersion formulation of lumefantrine (LUM-SDF) in pediatric patients (6 months to < 18 years of age) with uncomplicated P. falciparum malaria. There is an unmet medical need for anti-malarial treatment with a new mechanism of action to reduce the probability of developing resistance.
Malaria, schistosomiasis and ancylostomiasis are three parasitic diseases which affect hundreds of millions of people and are an important cause of global mortality and morbidity. For the control of these poverty related parasitic diseases, and to complement chemotherapeutic strategies, accurate and accessible diagnostic procedures play a crucial role. In recent years, innovative smart mobile technologies have been applied for detection and identification of cultured parasite species, which is basically based on sample imaging and parasite morphology identification. Promising advances have been made with this technology and coupled with its small size, low cost and easy to manipulate, makes it suitable for point of care diagnostics in low resource setting. The aim of the proposed explorative study is to further validate sensitivity and specificity of each of the developed devices, using besides microscopy a range of more advanced reference tests.
The trial is designed as a phase III, double-blind, multicenter, randomized, single administration, active-controlled, parallel-group design with two groups of newborn infants receiving either VPM1002 or BCG SII (1:1 allocation) to assess the efficacy, safety and immunogenicity of VPM1002 against Mtb infection.
Soil-transmitted helminths (STHs) infections are common in subtropics and mostly affect the poorest communities, with an impact on human health in many parts of the world. In 2017, World Health organization (WHO) reports more than 1.5 billion people are infected with soil-transmitted helminths worldwide, including 568 million school-age children who need treatment and preventive interventions. Preventive chemotherapy and periodic mass administration with benzimidazoles (BZ) [albendazole (ABZ) and mebendazole (MBZ)] are used to control these parasites. However, rapid reinfection with Ascaris lumbricoides within six months after a completed treatment has been reported, while the reinfection with hookworms is slow. Similarly, the efficacy of these drugs on Trichuris trichiura cure rate is poor. After many years of use of this drug class, there is an increase possibility that BZ resistance could develop. This resistance may occur due to single nucleotide polymorphisms (SNPs) in the β-tubulin gene at positions 167, 198 or 200, as has been reported in animals. Little data exist to show whether any of these polymorphisms do influence the BZ efficacy against STH in humans. The present study will develop methods to look for molecular evidence of BZ drug resistance in human population in order to support the investigation of the control and elimination of neglected tropical diseases (NTDs) in our communities.
Purpose: To examine whether helminth infection during pregnancy alters Vitamin-D-metabolism and reactivity of the child's immune system Hypothesis: Helminth infection during pregnancy is associated with altered Vitamin D levels and Vitamin D receptor expression in the placenta and modified immune reactivity in the infant.
Open labelled, non randomized study to evaluate the effects of Artemisinin based Combined Therapies(ACTs) on schistosomiasis since Praziquantel (PZQ) which is presently the drug of choice for treating Schistosomiasis (STS), is ineffective on immature stages and there is known parasite resistance. ACTs when combined with PZQ, targeting different stages of the life cycle has shown some effectivity.
It is unclear whether individual treatment of scabies is similarly effective compared to household treatment. This study therefore compares these two treatment strategies with topical benzyl benzoate for treating scabies in Lambaréné and surroundings in Gabon. Subjects presenting with uncomplicated scabies are randomized into either the Individual Treatment group, where only the affected subjects receive treatment, or the Household Treatment group, where all family members are treated in parallel to the affected subjects regardless of signs and symptoms. The primary endpoint is clinical cure after 28 days; the secondary endpoint is the proportion of affected household members per household after 28 days.
The ultimate aim of this registry is to collect precise information concerning the children coming to oncology units working with the French African Oncology Group. This data will help to plan and provide correct pediatric oncology treatment and care for this population. Collecting the data will give much needed information on numbers, stage, treatment and outcome. The register will give data for local and national health authorities in planning pediatric cancer programs.
