What this trial studies

This study evaluates the safety and efficacy of QTORIN 3.9% Rapamycin Anhydrous Gel in treating microcystic lymphatic malformations over a 24-week period. Approximately 40 participants aged 6 years and older with confirmed superficial microcystic lymphatic malformations will be enrolled. The study will assess changes in the condition using a baseline-controlled approach, with an option for participants to continue treatment beyond 24 weeks. The primary outcome will focus on the improvement of the condition as measured by the Investigator's Global Assessment (IGA).

Who should consider this trial

Good fit: Ideal candidates are children and adolescents aged 6 years and older with clinically confirmed superficial microcystic lymphatic malformations.

Not a fit: Patients with complicated vascular anomalies requiring systemic therapy or those with treatment areas in wet mucosa or within the orbital rim may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a non-invasive option for managing microcystic lymphatic malformations in patients.

How similar studies have performed: Other studies have explored topical treatments for vascular malformations, but this specific approach with QTORIN gel is novel.
