Brief summary

This study will enrol participants 6 months of age through age 13 with molluscum contagiosum (MC) across up to 6 sites in Australia. Participants will be randomly placed into one of two groups in a 2:1 ratio. This means twice as many children will receive the study treatment (Zabalafin Hydrogel) compared with those who receive the placebo. The purpose of the study is to see how well Zabalafin Hydrogel 9.5% works and how safe it is when used twice a day to treat MC. The main goal is to find out how many participants have more than 75% of their MC cleared by Week 16.

Interventions

Zabalafin Hydrogel 9.5%, A thin layer of the Zabalafin Hydrogel 9.5% gel will be applied to each MC lesion, twice daily, roughly 8 hours apart (around same time of the day) to all treatable MC lesions starting from Study Day 1 until the final dose at Day 112. Participants will be provided with a diary on Study Day 1 to record each daily gel application. The diary will be reviewed by the investigator at every study visit through Week 16.
