A Study to Assess the Efficacy and Safety of Mebendazole for the Treatment of Helminth Infections in Pediatric Participants

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.

Matching placebo will be administered as a single-dose 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.
