Secondary Outcome Measures

Egg Count Reduction Rate (Percent) for Ascaris Lumbricoides Infestation at the End of Double-blind Treatment Period
Percent egg count reduction is calculated as average egg count at end of treatment period of a treatment group minus average egg count at baseline of the treatment group divided by average egg count at baseline of the treatment group.
Egg Count Reduction Rate (Percent) for Trichuris Trichiura Infestation at the End of Double-blind Treatment Period
Percent egg count reduction is calculated as average egg count at end of treatment period of a treatment group minus average egg count at baseline of the treatment group divided by average egg count at baseline of the treatment group.
Maximum Plasma Concentration (Cmax) of Mebendazole
The Cmax is the maximum plasma concentration.
Time to Reach Maximum Plasma Concentration (Tmax) of Mebendazole
The Time to Reach Maximum Plasma Concentration (Tmax) is time to reach the maximum plasma concentration.
Area Under the Plasma Concentration-time Curve From Time 0 to 8 Hours (AUC8h) of Mebendazole
The (AUC8h) is the area under the plasma concentration-time curve from time 0 to 8 hours Post-dose.
Area Under the Plasma Concentration-Time Curve From Time Zero to Time of the Last Quantifiable Concentration AUC(0-last) of Mebendazole
The (AUC [0-last]) is the area under the plasma concentration-time curve from time 0 to time of the last quantifiable concentration.

5. Study Description

Brief Summary
The purpose of this study is to evaluate the efficacy and safety of mebendazole compared with placebo in pediatric participants with Helminth infections.
Detailed Description
This will be a double-blind (neither physician nor participant knows the treatment that the participant receives), randomized (the study drug is assigned by chance), multi-center, parallel-group study (each group of participants will be treated at the same time) to evaluate the efficacy and safety of mebendazole (a drug currently being investigated for Helminth gastrointestinal infections) compared with placebo (an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial) in children (including pre-school and school-aged children) with Helminth infections. The study will consist of 3 phases: a screening phase, a double-blind treatment phase, and a post-treatment (or follow-up) phase. A pharmacokinetic (explores what a drug does to the body) open-label substudy (asks a separate research question from the parent study while using the same participant population but does not contribute to the parent study's objectives) will be included in the parent study to measure the level of mebendazole in the blood. Safety assessments will be performed throughout the study. Each participant will take part in the study for approximately 30 days.

Intervention Type
Drug
Intervention Name(s)
Mebendazole
Intervention Description
Mebendazole will be administered as a single-dose 500 mg chewable tablet. For children 1 year to <36 months of age, the tablet will be placed in a teaspoon and bottled water will be poured into the remaining volume of the teaspoon. The tablet will then be allowed to absorb all water (absorption time has been observed to take less than 1 minute) to become a soft semi-solid mass without any hard particles. This semi-solid form can then be easily ingested by the child.
