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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing a new adhesive system that seals the great saphenous vein in people with varicose veins. The trial compares this adhesive, delivered through a tube, with radiofrequency ablation, a standard treatment that uses heat to close the vein. About 179 adults with varicose veins will be randomly assigned to one of the two treatments. The main goal is to see whether the adhesive closes the vein as completely as the heat treatment, based on ultrasound scans.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a vein closure adhesive delivered through a tube to seal the diseased vein
What this could lead to
If it works, the adhesive could offer a treatment that seals varicose veins without the heat and nerve irritation that radiofrequency ablation can cause.
What could go wrong
The trial is relatively small and compares the adhesive only against one standard treatment. The adhesive may fail to close the vein completely, or it may cause reactions that heat-based treatment avoids.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

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

Ages

18 to 80 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: 1. Age ≥ 18 years and ≤ 80 years at the time of screening, no restrictions on gender. 2. Clinical diagnosis of unilateral / bilateral varicose GSV of lower extremities. This operation only deals with unilateral trunk of GSV. 3. CEAP classification of C2 - C4b. 4. Ability to understand the requirements of the study, provide informed consent, and attend follow-up visits. Exclusion Criteria: 1. Life expectancy \<1 year. 2. Patients with vessel diameter \< 3mm or \> 12mm in the target segment of the GSV. 3. Deep vein thrombosis (DVT) (excluding intermuscular venous thrombosis) or pulmonary embolism (PE). 4. Undergone interventional or surgical treatment of the GSV in the target limb. 5. Allergies to lidocaine or cyanoacrylates. 6. GSV was extreme distorted and thus unsuitable for minimally invasive interventional treatment. 7. Aneurysm of the target vein with local vein diameter \>12 mm. 8. Active superficial thrombophlebitis in the target GSV. 9. Pregnant and / or lactating patients. 10. Patients who are participating in clinical trials of other drugs or medical devices. 11. Patients considered ineligible for inclusion by the investigator.
