What this trial studies

This Phase 2 clinical trial assesses the safety and efficacy of a 3.9% topical gel containing sirolimus for patients with cutaneous venous malformations. Participants will apply the gel to the affected area, which may include a minor lymphatic component. The study is baseline-controlled, meaning it will compare results against a baseline measurement to evaluate the gel's effectiveness. The trial aims to gather data on how well the treatment works and its safety profile.

Who should consider this trial

Good fit: Ideal candidates are individuals with clinically confirmed superficial cutaneous venous malformations visible on the skin.

Not a fit: Patients with lesions primarily located in wet mucosa or those with extensive involvement of deeper tissues may not benefit from this treatment.

Why it matters

Potential benefit: If successful, this treatment could provide a non-invasive option for patients suffering from cutaneous venous malformations.

How similar studies have performed: While this approach is novel, similar studies evaluating topical treatments for vascular malformations have shown promise.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria: The participant must have a clinically confirmed superficial/ cutaneous (visible on the skin) venous malformation (cVM), referred to as the treatment area. The treatment area may contain a minority (\<30%) lymphatic component (mixed venous / lymphatic malformation).

-

Exclusion Criteria:

* The participant's treatment area is mainly in any wet mucosa or within the orbital rim. For clarification, no part of the venous malformation should be evaluated or treated if it in mucosa. External genital presentation is permitted.
* The participant has a known pervasive extension of the lesion into mucosa, bone or tissue (as determined by diagnostic or the investigator) that would impair the ability of the investigator to evaluate the cutaneous components of the lesion.
