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.
Objective 1.To characterize the plasma disposition kinetics of ABZ and its main metabolites (ABZ sulphoxide and ABZ sulphone) in non-infected human volunteers.

Objective 2. To characterize the pattern of albendazole (ABZ) and its main metabolites (ABZ sulphoxide and ABZ sulphone) urinary excretion in non-infected human volunteers.

Objective 3. To determine the optimal and the longest period time after treatment where either ABZ and/or its metabolites can be measured in urine as an indirect assessment of an individual's adherence to treatment.
