Can targeted drugs tame complex vascular anomalies? a registry seeks answers
NCT ID NCT07767877
First seen Aug 17, 2026 · Last updated Sep 02, 2026 · Updated 3 times
Summary
This study gathers real-world data from medical records of patients with complex vascular anomalies treated with targeted therapies like mTOR inhibitors, MEK inhibitors, or PI3K inhibitors. Researchers will look at patient characteristics, treatment patterns, and side effects across multiple US centers. The goal is to better understand how these drugs are used in everyday practice and what outcomes patients experience.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Targeted therapies including mTOR inhibitors (sirolimus/everolimus), MEK inhibitor (trametinib), and PI3K inhibitor (alpelisib)
- What this could lead to
- This registry could help doctors understand how targeted therapies are used in real-world practice for vascular anomalies, potentially improving treatment decisions and patient care.
- What could go wrong
- As a registry study, it does not test new treatments directly. It relies on existing medical records, which may be incomplete or vary across centers, and cannot prove which treatment works best.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion criteria: * Diagnosed with a spectrum of vascular anomalies including but not limited to congenital vascular and lymphatic anomalies, vascular tumors and lymphatic malformations, and acquired vascular malformations. * Treated with ≥1 of mammalian target of rapamycin (mTOR) inhibitors, mitogen-activated protein kinase/ERK kinase (MEK) inhibitors and phosphoinositide 3-kinase (PI3K) inhibitors continuously for 3 months. Exclusion criteria: * Patients diagnosed with a vascular anomaly who have not been treated with mTOR inhibitors, MEK inhibitors and PI3K inhibitors for at least 3 months. * Patients with other complex medical conditions; i.e. rare genetic syndromes. * Patients receiving many other systemic therapies making data collection not feasible. * Recurrent use of immunosuppressive agents, i.e. systemic steroids or targeted medical therapies for oncologic disorders, etc. * Patients with significant gaps in data collection. * Patients with concurrent enrollment in interventional trials. Other protocol-defined inclusion/exclusion criteria may apply.
