What this trial studies

This Phase 2a/b open-label study evaluates the safety and efficacy of TARA-002, administered via intracystic injection, for treating macrocystic and mixed cystic lymphatic malformations in children aged 6 months to less than 18 years. The study begins with a safety lead-in phase for older participants before expanding to younger cohorts. Participants will receive up to four injections spaced approximately six weeks apart, with safety being established at each age level before proceeding to the next. The study aims to confirm the effectiveness of TARA-002 in reducing lymphatic malformations.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for children suffering from lymphatic malformations, potentially improving their quality of life.

How similar studies have gone: While this approach is novel, similar studies targeting lymphatic malformations have shown promise, indicating potential for success.
