Safety and Efficacy Study of Intracystic TARA-002 for the Treatment of Lymphatic Malformations in Participants 6 Months to Less Than 18 Years of Age

Purpose

This is a Phase 2a/b single arm open label study to evaluate the safety, reactogenicity, and efficacy of intracystic injection of TARA-002 in participants 6 months to less than 18 years of age for the treatment of macrocystic and mixed cystic lymphatic malformations. The Phase 2a safety lead-in, age de-escalation study is designed to establish the safety of TARA-002 in older participants 6 years to less than 18 years before proceeding to younger participants 2 years to less than 6 years, then 6 months to less than 2 years. The Phase 2b is an expansion study in which enrollment of participants will be initiated after safety has been established in each cohort during the Phase 2a safety lead-in study. Each participant will receive up to 4 injections of TARA-002 spaced approximately 6 weeks apart.
