NCT ID: NCT03931473 Active, not recruiting - Anemia Clinical Trials

Efficacy of Two Dual Active Ingredient Long Lasting Insecticidal Nets for Control of Malaria Transmitted by Pyrethroid Resistant Vectors in Benin

NNP
Start date: June 1, 2020
Phase: N/A
Study type: Interventional

The massive scale-up of Long Lasting Insecticidal Nets (LLIN) has led to a major reduction in malaria burden (up to 50%) in many sub-Saharan African countries. This progress is threatened by the wide scale selection of insecticide resistant malaria vectors. New types of LLIN combining a mixture of two insecticides have been developed to control resistant mosquitoes. The efficacy of two bi-treated LLIN are compared to a standard LLIN in a three-arm, single blinded, cluster-randomized trial in Cove, Benin. The arms are; 1/ Royal Guard, a net combining pyriproxyfen (PPF), which is known to disrupt female reproduction and fertility of eggs, and the pyrethroid alpha-cypermethrin, 2/Interceptor G2, LLIN incorporating a mixture of two adulticides with different modes of action; chlorfenapyr and a pyrethroid (alpha-cypermethrin), and 3/ The control arm: Interceptor, a standard LLIN treated with alpha-cypermethrin. The primary outcome of the trial will be malaria case incidence in children aged 6 months to 10 years.

FEVRIER study is an observatory of hospitalizations in cardiology units in sub-Saharan Africa.

NCT ID: NCT03014167 Active, not recruiting - Helminthiasis Clinical Trials

Field Studies on the Feasibility of Interrupting the Transmission of Soil-transmitted Helminths (STH)

Start date: October 4, 2017
Phase: Phase 3
Study type: Interventional

Over 1.5 billion people are infected with soil-transmitted helminths (STH). Global STH guidelines recommend MDA (mass drug administration) of albendazole or mebendazole to targeted populations, including pre-school age children and school-age children. However mathematical models suggests that current MDA strategies are not sufficient for interrupting disease transmission in most areas. Meanwhile many lymphatic filariasis (LF) programs have successfully treated entire populations with albendazole (in combination with ivermectin or diethylcarbamazine) and are transitioning to a state of post-MDA surveillance. This project will conduct a series of community-based cluster randomized trials in India, Malawi, and Benin to determine if maintaining three years of MDA with albendazole to entire communities following the cessation of LF programs can interrupt STH transmission in focal geographic areas. Additionally, this study aims to compare the efficacy of community-wide MDA versus targeted MDA of children in interrupting the transmission of STH. Nested implementation science research will be used to optimize the intervention, identify contextual factors influencing trial efficacy, and evaluate the feasibility of sustaining and scaling community-wide MDA for STH. These data will provide evidence necessary to inform future guidelines, policies, and operational plans as country partners engage in intensified approaches to eliminate these disabling diseases.

NCT ID: NCT02979080 Active, not recruiting - Iron Absorption Clinical Trials

Iron Long-Term Labelling Study Benin

Start date: June 10, 2017
Phase: N/A
Study type: Interventional

Conventional indirect indicators of iron status, using serum and red blood cell biomarkers, are confounded by inflammation from common infections in sub-Saharan Africa, a region with a high prevalence of iron deficiency, making the assessment of iron balance and efficiency of iron intervention difficult. A potential reference method to quantify iron absorption and requirements using isotope dilution measurements in women living in areas with high burden of infection should be developed and validated within this project. The new method will allow accurate measurement of long term oral iron absorption and the estimation of iron requirements, potentially providing fundamental guidance for supplementation and fortification programs in sub-Saharan Africa. In a case series with four months' preventative iron supplementation intervention imbedded between a four months' control period prior intervention and a four months' control period after intervention, we will follow a group of 63 women. During the intervention period, the women will receive 50 mg Fe as ferrous sulfate tablets every day for 120 d. In total, the women will give 9 blood samples (day 1, 60 120, 150, 180, 210, 240, 300 and 360) for the de-termination of the isotopic composition and iron status biomarkers and 5 stool samples (day 1, 120, 180, 240 and 360) for the detection of soil transmitted helminths and gut inflammation. This design will allow the measurement of the isotopic iron dilution to assess the total oral iron absorption during the intervention period in comparison with the control periods without the administration of additional iron isotopes.
