Can targeted drugs tame complex vascular anomalies? a registry seeks answers

NCT ID NCT07767877

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Ages

0 to 90 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

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.
