There are about 51 clinical studies being (or have been) conducted in Benin. 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.
On a global scale, tuberculosis (TB) is the single most important infectious cause of morbidity and mortality. The World Health Organization has estimated that one-third of the entire world's population carries latent TB infection. A key TB control strategy is therapy of latent TB infection (LTBI). The current standard regimen is 9 months of Isoniazid (9INH). This regimen has excellent efficacy if taken regularly, but its effectiveness is substantially reduced by poor compliance. Serious side effects, such as hepato-toxicity can occur. Three shorter alternatives have been recommended: 6 months INH (6INH), 2 months Rifampin - Pyrazinamide (2RIF-PZA) and 4 months Rifampin (4RIF). The regimen of 6INH is less efficacious than 9INH, while 2RIF-PZA has been largely abandoned because of serious toxicity. Based on some evidence in treatment of LTBI, and extrapolating from extensive experience with treatment of active TB, it is believed that 4RIF has similar efficacy as 9INH. Therefore, the investigators are initiating the first multi-site international randomized trial that will compare the effectiveness of 4RIF and 9INH in preventing active tuberculosis.
The investigators performed a prospective study, in order to assess the feasibility and safety of restricting antimalarials to rapid diagnostic test (RDT)-confirmed cases in children aged 5 to 15 years-old
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.
The objective of this study was to determine the effectiveness and cost-effectiveness of a package of interventions to support health workers in Benin (in West Africa) who had been trained to use Integrated Management of Childhood Illness guidelines (i.e., guidelines intended to improve the treatment of childhood illnesses).
Malaria is a life-threatening disease especially in small children. A high degree of Plasmodium falciparum resistance to chloroquine has already spread to South-Benin where this study is taking place. In the past few years, the recommendation for a first-line treatment in this area has moved from chloroquine to sulfadoxine-pyrimethamine (SP). There is growing evidence that Plasmodium falciparum resistance to SP has come to South-Benin. The aim of the study is to compare the efficacy of SP to two compact artemisinin-based therapies (ACT): artemether-lumefantrine and the amodiaquine-artesunate coformulation. ACT will be unsupervised. The primary endpoint is an effectiveness comparison (PCR corrected) at day 28. Secondary outcomes are effectiveness comparisons (PCR corrected) at day 14 and 42 and a study on the relationships between ACT PK data (day 3) and outcome. Expected total enrollment: 225 patients Study start: April 2007; expected completion: December 2007
This study will evaluate the safety and efficacy of artemether-lumefantrine against uncomplicated malaria caused P. falciparum in children of 5-35 kg bodyweight.
Malaria in pregnancy is one of the most important preventable causes of low birthweight worlwide and a major cause of severe maternal anaemia contributing to maternal mortality. Intermittent Preventive Treatment (IPT) with sulfadoxine-pyrimethamine (SP) is the currently adopted government recommendation for malaria control during pregnancy in Benin, but the emergence and the spread of resistance to SP justifies the evaluation of alternative anti-malarial drugs. Mefloquine (MQ), which has been proven effective and reasonably safe in this indication, may be an interesting alternative to SP. The aim of this trial is to compare the efficacy and safety of sulfadoxine-pyrimethamine and mefloquine for IPT. It is an equivalent study designed to test the hypothesis that MQ is as efficacious as SP to prevent malaria in pregnancy, and that it could replace SP when resistance of Plasmodium falciparum becomes too elevated. Primary endpoint will be the proportion of infants with low birthweight. Secondary endpoints will be the proportion of mothers with placental plasmodial infection, and the proportion of mothers with anaemia at delivery.
Tuberculosis is currently treated with a 6-month course regimen. During this time many patients might fail to adhere to treatment and default, increasing the risk of recurrent disease which might be multidrug resistant. A shorter duration of treatment is expected to provide improved patient compliance and at least equal or better clinical outcome. The aim of the trial is to evaluate the efficacy and safety of a gatifloxacin-containing regimen of four months duration for the treatment of pulmonary tuberculosis,
Tuberculosis (TB) is spread by airborne transmission from adults with active contiguous TB to children, especially those living in the same household. Once children are exposed and infected they are at very high risk to develop active TB - which can be lethal if not detected and treated promptly. This makes it very important to detect TB infection as soon as possible, and treat this while it is still latent or dormant. Current therapy for latent TB infection is 9 months of Isoniazid; this is very effective if taken properly but because treatment is so long many children do not finish this. Four months of Rifampin is a recommended alternative. In adults this has been shown to be safer with much higher completion rates. However the effectiveness of this treatment is unclear, and is being studied in an ongoing study. The investigators plan to compare the safety as well as the acceptability and effectiveness of 4 months Rifampin with 9 months Isoniazid (standard treatment) in children in several sites in Canada and other countries. It is hypothesized that among children at high risk for development of active TB, intolerance/adverse events will not be worse (non-inferiority), among those randomized to 4RIF compared to those randomized to 9INH. In addition completion of latent tuberculosis infection (LTBI) therapy will be significantly greater (superiority), and subsequent rates of active TB will not be significantly higher (non-inferiority) in children taking 4RIF.
