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 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.
The objective of the study is to assess the efficacy and safety of SAR97276A in severe malaria in pediatric patients. Before treating pediatric patients with severe malaria, the efficacy and safety of SAR97276A will be first tested in adult patients, then in pediatric patients, with uncomplicated malaria. The safety and the concentration of SAR97276A in blood and plasma will be assessed in adult and pediatric patients.
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 study aims to show that the candidate malaria vaccine GMZ2 is as safe as the already publicly used vaccine against rabies. 30 Gabonese children aged 1-5 years will be enrolled and randomly allocated to receive either malaria vaccine or rabies vaccine without the investigator or the participants knowing what they received. They will receive 3 doses each at one month intervals, and will be followed up for one year to evaluate safety parameters. 30 and 100µg doses for the candidate malaria vaccine GMZ 2 will be evaluated for safety. This is the second time that candidate malaria vaccine GMZ 2 is being tested in Africa, the first time being in Gabonese adults where the product was found to be safe.
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.
The primary objective of this Phase III clinical study is to demonstrate the efficacy of the fixed combination of pyronaridine artesunate (PA) granule formulation (60:20 mg; pediatric PYRAMAX®) by showing a PCR-corrected adequate clinical and parasitological cure rate (ACPR) of more than 90%. Secondary objectives of this clinical study are to compare the efficacy (non-inferiority) and safety of the PA granule formulation compared to Coartem® (ie, the combination of artemether/lumefantrine [AL]) crushed tablets in a paediatric population and to assess the safety of the PA granule formulation.
The primary objective of the study is to evaluate the effectiveness of 2 intravenous artesunate dosing regimens (2.4 mg/kg initially and at 12, 24, 48, and 72 hours or 4.0 mg/kg initially and at 24 and 48 hours) in clearing P. falciparum parasites in children with severe malaria. Secondary objectives include: - To compare the tolerability and safety of the 2 intravenous artesunate dosing regimens. - To evaluate differences in the pharmacokinetic profile of intravenous artesunate by patient age and clinical presentation.
IPTi, a strategy whereby infants are provided treatment doses of antimalarials at routine vaccination visits, has been shown to significantly reduce malaria and anemia in two studies in Tanzania. However the results obtained in Gabon are not similar. Many factors are likely to influence the efficacy or effectiveness IPTi. It is reasonable to assume that the efficacy of IPTi will be influenced markedly by the sensitivity of Plasmodium falciparum to the antimalarial drug (Sulfadoxine-Pyrimethamine) used for IPTi. In order to interpret the results of individual IPTi trials conducted by the IPTi Consortium, and to provide information for policy makers regarding the predicted efficacy of IPTi, it is essential to obtain information on antimalarial drug sensitivity of Sulfadoxine-Pyrimethamine now that the IPTi trial has been conducted. The simplest and most universally accepted measure of testing for antimalarial drug efficacy is the "in vivo efficacy study," which follows a standardized World Health Organization protocol. A second reason for evaluating drug resistance as an adjunct to the IPTi trials is to determine if the intervention increases the carriage and/or spread of drug resistant P. falciparum parasites. Thirdly the overall effect at the community level of selection of resistant genotypes in IPTi-recipients is unclear.
This study is being done to assess the possibility of the potential integration of malaria vaccine into the EPI regimen. It will evaluate whether the malaria vaccine is safe and immunogenic in infants aged 6 to 10 weeks at first dose, when co-administered with other EPI vaccine antigens. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The study aims to show that the candidate malaria vaccine GMZ2 is as safe as the already publicly used vaccine against rabies. 40 adult male Gabonese volunteers will be enrolled and randomly allocated to receive either malaria vaccine or rabies vaccine without the investigator or the participants knowing what they received. They will receive 3 doses each at one month intervals, and will be followed up for one year to evaluate safety parameters. This is the first time this product will be tested in Africa
