PRIMARY outcome

Timeframe: 21 days

Population: The follow-up visit for efficacy assessment on Day 21 post-drug administration was not conducted in 52 subjects due to the outbreak of COVID-19 pandemic in Honduras which precluded completion of study visits in March 2020. Additional 7 subjects did not complete the study: 1 did not take the study medication, and 6 subjects were lost to follow up.

SECONDARY outcome

Timeframe: 21 days

Population: The follow-up visit for efficacy assessment on Day 21 post-drug administration was not conducted in 52 subjects due to the outbreak of COVID-19 pandemic in Honduras which precluded completion of study visits in March 2020. Additional 7 subjects did not complete the study: 1 did not take the study medication, and 6 subjects were lost to follow up.

Calculation details: 100 x (1 - arithmetic mean fecal egg count post-intervention / arithmetic mean fecal egg count pre-intervention) Egg change rate was calculated across all participants, as described in reference: Levecke B et al., PLoS Negl Trop Dis. 2014;8(10).

SECONDARY outcome

Timeframe: 21days

Measurement of the incidence of mutations of tubulin in Trichuris trichiura eggs collected pre and post treatment using molecular biology techniques. This data is not available yet due to the COVID-19 pandemic, but the data will be available and reported in the future. Anticipated reporting date for this outcome measure is estimated by 2021 and will be confirmed once the pandemic is over.
