Comparison Study for Safety and Efficacy of Two Devices for the Treatment of the Great Saphenous Vein (RECoN)

A Multi-Center, Randomized, Controlled Study to Evaluate the Efficacy and Safety of Subjects Comparing the NeverTouch Versus the RF ClosureFAST Methods of Treatment of the Great Saphenous Vein

This is a multi center, randomized, comparison study using two already cleared methods of treatment of the great saphenous vein (GSV). The hypothesis to be tested is that the use of the Venacure EVLT NeverTouch procedure is no worse than the RF ClosureFAST procedure for treatment of the GSV. Evaluation of post operative pain and bruising, quality of life assessments, adverse event assessments, confirmation of long term GSV closure, use of medications are criteria that will be evaluated during the course of this study.

Study Overview

• Status: Withdrawn
• Conditions: Varicose Veins; Venous Insufficiency
• Intervention / Treatment: Device: VenaCure EVLT NeverTouch; Device: VNUS RF ClosureFAST

Detailed Description

Some form of venous insufficiency affects up to 25% of men and 40% of women in the United States. While most persons seek treatment because varicose veins are unsightly, most will also experience symptoms such as aching pain, night cramps, leg fatigue, leg heaviness or leg restlessness. If left untreated, nearly 50% of patients with significant superficial venous insufficiency will experience chronic venous insufficiency characterized by lower extremity swelling, eczema, pigmentation, hemorrhage and ulceration.

This is a multicenter, prospective, randomized study in subjects with symptomatic venous insufficiency of the great saphenous vein. Subjects evaluated for participation will be those who, prior to the first visit, have elected to receive invasive treatment for the GSV insufficiency and have already received conservative treatment (i.e. use of compression hose).

Subjects will be randomized to receive one of two methods of treatment. VenaCure EVLT NeverTouch method of treatment or the RF ClosureFAST method of treatment.

Follow up visits will take place at 2, 7, 14 and 30 days post treatment where questionnaires (SF-36, CIVI Q2, Visual Analogue Scale), evaluation of GSV closure via duplex ultrasound (7 day and 30 day only), evaluation of ecchymosis, physician (or their designee) evaluation of venous disease (CEAP assessment and VCSS assessment), assessments of adverse events and review of concomitant medications (use of analgesics and other medications)will take place. These same evaluations with the exception of the use of the Visual Analogue Scale and the Ecchymosis evaluation will also take place at the 6 month and 12 month follow up visit timepoints.

• C2 disease
• C3 disease
• C4A, C4B disease
• C5 disease
• C6 disease
• have not been previously treated for GSV,
• have multilevel venous reflux in the great saphenous vein greater than 0.5 seconds after distal compression/ release in the standing position,
• have palpable dorsalis pedis/ anterior tibial pulse or ABI >0.9 (unless calcified pressures) at screening,
• are able to comply with the protocol requirements,
• are able to comprehend and willing to sign an Informed Consent Form (ICF).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: VenaCure EVLT NeverTouch	Device: VenaCure EVLT NeverTouch; Endovenous Laser Treatment (EVLT) uses laser energy, which is a highly concentrated beam of light to treat varicose veins.; Other Names: VenaCure; EVLT; NeverTouch
Active Comparator: RF ClosureFAST	Device: VNUS RF ClosureFAST; VNUS® RF ClosureFAST is a minimally invasive varicose vein treatment procedure that uses radiofrequency energy (electricity) to heat, collapse and seal off the targeted blood vessels.; Other Names: Closure

What is the study measuring?

Outcome Measure	Time Frame
Incidence of post operative adverse events/ effects between the two treatment groups.	Evaluated on the day of treatment (post treatment), 2, 7, 14, and 30 days and 6 and 12 months post treatment follow up visits.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evaluation of GSV closure and incidence of DVT via duplex ultrasound between the two treatment groups.		Evaluated at 7 and 30 days post treatment and 6 and 12 months post treatment follow up visits.

The questionnaires for quality of life will be used for each of the visits including the 6 and 12 month follow up visits.	Evaluated at 2, 7, 14 and 30 days and 6 and 12 months post treatment follow up visits.
Presence and intensity of post operative ecchymosis between the two treatment groups.	A blinded healthcare professional (selected by the PI at each site) will evaluate the subject at the designated timepoints.	Evaluated 2, 7, 14 and 30 days post treatment follow up visits.
Use of Analgesics within the 30 days post treatment between the two treatment groups.		Reviewed at 2, 7, 14 and 30 days post treatment follow up visits.
