What this trial studies

This clinical trial investigates the effectiveness of administering sirolimus once a week for patients with venous and lymphatic malformations. The study aims to assess not only the therapeutic benefits of this dosing schedule but also patient satisfaction and any adverse effects experienced during the treatment. Participants will receive the medication for a duration of six months, with the possibility of continuing treatment afterward. The trial seeks to provide a safer alternative to daily dosing, which is associated with significant side effects.

Why it matters

Potential benefit: If successful, this treatment could offer a more manageable and effective option for patients suffering from venous and lymphatic malformations.

How similar studies have gone: While the use of sirolimus has shown promise in other studies, this specific approach of weekly dosing is novel and has not been extensively tested.
