Clinical Trial Summary

This trial was designed as a prospective, multi-center, randomized clinical trial of the FDA-cleared Vari-Lase Bright Tip Fiber compared to commercially available standard bare-tip laser fiber (control) to demonstrate the safety and effectiveness of laser ablation for the treatment of varicose veins associated with reflux within the great saphenous vein (GSV) and to provide additional data concerning patient satisfaction. Within this evaluation, subject limbs were randomized to one of two (2) treatment groups utilizing a 1:1 randomization ratio. If a subject required treatment of only one limb, that limb was randomized to a treatment group. If a subject required treatment of two limbs, the first limb was randomly assigned treatment and the second limb was assigned the other treatment (the opposite treatment of the other limb). The data was analyzed by treated limb (versus treated subject).All study data were analyzed under the principles of intent-to-treat, in which data are analyzed according to the assigned randomized group regardless of the treatment actually delivered. Subjects were followed at one week, one month, and six months.

Description:

This trial was designed as a prospective, multi-center, randomized clinical trial of the FDA-cleared Vari-Lase Bright Tip Fiber compared to commercially available standard bare-tip laser fiber (control) to demonstrate the safety and effectiveness of laser ablation for the treatment of varicose veins associated with reflux within the great saphenous vein (GSV) and to provide additional data concerning patient satisfaction. Subjects were pre-screened utilizing standard of care data (including documented evidence of reflux within the GSV) for the specified inclusion/exclusion criteria to ensure that they were eligible for treatment in the investigation. Prior to laser treatment and after signing an informed consent form, study eligibility assessments were completed including physical assessment of target limb(s), duplex ultrasound of GSV segment(s) targeted for treatment, symptom assessment, medical history, and digital photos of targeted limbs. Upon enrollment, targeted limbs were randomized at a 1:1 ratio to receive the Vari-lase Bright Tip Fiber or the control treatment. If the subject required treatment of two limbs, the first limb was randomized and the second limb was assigned the other treatment (the opposite treatment of the other limb). Immediately post procedure, subjects were assessed for adverse events and a physical assessment of the treated limb(s) was performed. Subjects were also asked to complete a subject pain and satisfaction questionnaire. Subjects were followed at one week, one month, and six months. Follow-up included a physical assessment of treated limb(s), symptom assessment, adverse event assessment, and completion of a subject pain and satisfaction questionnaire. Additionally, a duplex ultrasound assessment was conducted at one week and six months and digital photos were taken of the treated vein segment(s) at one week and one month. The data was analyzed by treated limb (versus treated subject). All study data were analyzed under the principles of intent-to-treat, in which data are analyzed according to the assigned randomized group regardless of the treatment actually delivered.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Limbs With a Continued Absence of Flow Within the Treated Vein Segment Over 6 Months.	The absence of flow was evaluated in each treated limb and determined by ultrasound (duplex or Doppler) interrogation.	6 Months	No
Primary	Number of Limbs With a Device-related Serious Adverse Event Reported Over 6 Months.	Each treated limb was clinically evaluated for the presence of a device-related serious adverse event.	6 Months	Yes
Secondary	Percent Change of Subject Symptoms in Treated Limb From Baseline to 6 Months Using Venous Clinical Severity Score (VCSS).	VCSS is a physician's evaluation of 10 pre-determined clinical signs or attributes of venous disease (pain, varicose veins, venous edema, skin pigmentation, inflammation, induration, number of active ulcers, active ulcer duration, active ulcer diameter and compression therapy). Each attribute receives a score from 0-3 (0=absent and 3=severe). The best total overall score is 0 (all ten attributes are absent) and the worse overall score is 30 (all ten attributes are severe). Each treated limb was evaluated and scored at baseline and at 6 months.	6 Months	No
Secondary	Percent Change of Subject Symptoms in Treated Limb From Baseline to 6 Months Using Venous Disability Score (VDS).	VDS is a physician's evaluation of a patient's ability to work an eight-hour day with or without a support device (i.e., compressive therapy, limb elevation). The patient is scored on a scale of 0-3 (0=asymptomatic and 3=unable to carry out usual activities (patients activities before the onset of disability due to venous disease) even with compression and/or limb elevation). The score represents the degree of disability caused by the venous disease with the best score being 0 and the worse score being 3. Each treated limb was evaluated and scored at baseline and at 6 months.	6 Months	No
Secondary	Percent Change of Subject Symptoms in Treated Limb From Post-procedure to 6 Months Using Patient Visual Analog Scale (VAS) Pain Scores.	Each subject completed a questionnaire to rate his/her pain. The scale is from 0-10 (0=no pain and 10=worst pain imaginable). Each treated limb was scored by the patient post-procedure and at 6 months to determine the improvement after treatment at the 6-month time point.	6 Months	Yes
Secondary	Percentage of Subjects Reporting an Excellent Satisfaction Score at 6 Months.	Each subject completed a questionnaire to rate their satisfaction with the laser treatment. The score was reported as excellent, good, fair or poor. The best score of excellent was defined as "I am very satisfied with the laser treatment" and the worse score of poor was defined as "I am not satisfied with the laser treatment." Each treated limb was scored by the patient at 6 months to determine the percent satisfaction at the 6-month time point.	6 months	No
Secondary	Number of Limbs With a Device-related Non-serious Adverse Event Reported Over 6 Months.	Each treated limb was clinically evaluated for the presence of a device-related non-serious adverse event.	6 Months	Yes
