Study Details

Study Description

Brief Summary

This study is a single-blind randomized clinical trial conducted in rural Côte d'Ivoire. This study aims at providing evidence on the dose-response of increasing oral albendazole dosages against whipworm (T. trichiura) and hookworm infections in preschoolers (2-5 years), school-aged children (6-12 years) and adults (≥ 21 years).

The primary objective is to determine cure rates (primary end point, i.e. conversion from being egg positive pre-treatment to egg negative post-treatment). Secondary objectives involve the determination of egg reduction rates (the reduction in the number of excreted eggs from baseline (prior to treatment) to follow-up) and the assessment of safety of ascending dosages of albendazole (secondary end points). In addition, key pharmacokinetic parameters will be determined from blood samples collected with a micro-sampling device (secondary end point).

Detailed Description

This study is a single-blind randomized clinical trial conducted in Côte d'Ivoire. This study aims at providing evidence on the efficacy and safety of ascending oral albendazole dosages in children and adults infected with T. trichiura and hookworm. In preschool-aged children (2-5 years) (i) 200 mg, (ii) 400 mg and (iii) 600 mg; in schoolchildren (6-12 years) and adults (≥ 21 years) (i) 200 mg (only for hookworm infections), (ii) 400 mg, (iii) 600 mg and (iv) 800 mg will be administered and efficacy, safety and pharmacokinetic parameters will be assessed.

The primary objective is to determine the dose-response based on cure rates of albendazole in preschool-aged children (2-5 years), school-aged children (6-12 years) and adults (≥ 21 years) infected with T. trichiura and hookworm.

The secondary objectives of the trial are to determine the efficacy based on egg reduction rates of albendazole in preschool-aged children, school-aged children and adults, to determine an exposure (including length of time that the drug concentration is above the MIC, Cmax, AUC)-response correlation of albendazole in preschool-aged children, school-aged children and adults, to evaluate the safety and tolerability of albendazole in preschool-aged children, school-aged children and adults, and to determine the efficacy against concomitant soil-transmitted helminthiasis (Ascaris lumbricoides).

After obtaining informed consent from individual/parents and/or caregiver, the medical history of the participants will be assessed with a standardized questionnaire, in addition to a clinical examination and venipuncture to examine biochemical parameters in the blood carried out by the study physician before treatment. Enrollment will be based on two stool samples that will be collected, if possible, on two consecutive days or otherwise within a maximum of 5 days.

All stool samples will be examined with duplicated Kato-Katz thick smears by experienced laboratory technicians. Randomization of participants into the treatment arms will be stratified according to intensity of infection. All participants will be interviewed before treatment, 3 and 24 hours and 3 weeks after treatment about the occurrence of adverse events. Children and adults will be sampled using finger pricking for micro-blood sampling at 0, 1, 2, 3, 4, 6, 8, 24 hours post-dosing.

The primary analysis will include all participants with primary end point data (available case analysis). Supplementary, a per-protocol analysis and an intention-to-treat analysis will be conducted. CRs will be calculated as the percentage of egg-positive subjects at baseline who become egg-negative after treatment. Differences among CRs will be analysed by using crude logistic regressions and adjusted logistic regressions (adjustment for age, sex, and height).

Geometric and arithmetic mean egg counts will be calculated for the different treatment arms before and after treatment to assess the corresponding ERRs. Bootstrap resampling method with 2,000 replicates will be used to calculate 95% confidence intervals (CIs) for differences in ERRs. Noncompartmental and nonlinear mixed-effects (NLME) modeling will be used to determine PK parameters.

    Outcome Measures

    Primary Outcome Measures

    1. Cure Rate Against T. Trichiura and Hookworm Infections [14-21 days after treatment]

      The conversion from being egg positive pre-treatment to egg negative post-treatment, or cure rate (CR).

    Secondary Outcome Measures

    1. Egg-reduction Rate (ERR) Against T. Trichiura and Hookworm Infections, Respectively [14-21 days after treatment]

      Percent change in geometric mean eggs per gram of stool from before to after treatment

    Description To determine maximum drug concentration (Cmax) of albendazole and its metabolites in adults (≥ 21 years), preschool-aged (2-5 years) and school-aged children (6-12 years). Albendazole and its metabolites (albendazole sulfoxide and albendazole sulfone) will be quantified using a validated liquid chromatography tandem mass spectrometry (LC-MS/MS) method. Drug concentrations will be calculated by interpolation from a calibration curve with a foreseen limit of quantification of approximately 1-5 ng/ml.
