Filter by:This trial aims to evaluate the efficacy, tolerability and safety of adjunct metformin added to standard-of-care multi-drug therapy (MDT) in patients with multibacillary leprosy, and explore its effects on immunological endpoints. A double-blind, placebo controlled proof-of-concept trial will be performed in which patients with newly diagnosed multibacillary leprosy will be randomized (1:1) to metformin 1000mg OD versus placebo for 24 weeks in addition to MDT during 48 weeks. The main research question is whether adjunctive metformin, combined with MDT, will improve the clinical outcomes of patients with multibacillary leprosy by mitigating leprosy reactions, thereby reducing nerve damage and corticosteroid use and its associated morbidity. The second aim is to explore whether adjunct metformin, added to MDT, has an acceptable tolerability and safety in patients with multibacillary leprosy.
This is a cluster-randomized placebo-controlled clinical trial to evaluate the additive benefit of Ivermectin (IVM) (or Placebo) mass drug administration (MDA) to dihydroartemisinin-piperaquine (DP) MDA for malaria control in a moderate to low malaria-endemic setting as an adjunctive strategy to existing programmatic malaria control measures. The regime of DP and IVM will target both human reservoirs of Plasmodium falciparum and the Anopheles gambiae vector respectively, with the aim of interrupting transmission. The trial will be conducted on the Bijagos Archipelago, where islands (clusters) will be randomised to receive seasonal DP and IVM or DP and Placebo MDA. The primary outcome will be the prevalence of infection with Plasmodium falciparum in all age groups detected by nucleic acid amplification testing during the peak malaria transmission season after two years of intervention.
Mass drug administration (MDA) of albendazole (ABZ) to school-age and pre-school-age children is the currently recommended strategy for controlling soil-transmitted helminthiasis (STH) in endemic areas. Recent mathematical modelling suggests that community-wide MDA will be required in order to interrupt transmission of STH. DEWORM3 aims to determine the feasibility of eliminating STH through expanded and intensified MDA strategies. In order to ensure rigorous trial results, it is crucial that the definition of such MDA coverage is informed by unbiased, empirical data. The Centro de Investigación Veterinaria de Tandil (CIVETAN) and Instituto de Investigaciones en Enfermedades Tropicales Universidad Nacional de Salta collaborate on scientific research related to pharmacokinetic studies of ABZ. This proposal describes the request for funding from DEWORM3 to conduct a study of the serum pharmacokinetic characteristics and urinary excretion of ABZ and its metabolites in non-infected human volunteers to better understand the use of urinary analysis of ABZ as a measure of MDA adherence in the context of DEWORM3.
