Viveve I Study
Introduction: Vaginal laxity is a highly prevalent and undertreated medical condition.
Aim: To evaluate the efficacy and safety of surface-cooled, monopolar radiofrequency (RFc) therapy for the treatment of vaginal laxity in the VIVEVE I trial.
Methods: The VIVEVE I trial was a prospective, randomized, single-blinded, and sham-controlled study. Nine study centers in Canada, Italy, Spain, and Japan participated. Women presenting with vaginal laxity were screened and informed consent was obtained.Major study inclusion criteria were premenopausal status, age at least 18 years, at least one full-term vaginal delivery, and normal genito-pelvic examination results. Enrolled subjects were randomized (2:1) to receive RFc therapy (Active [90 J/cm2] vs Sham [1 J/cm2], respectively) delivered to the vaginal tissue.
Main Outcome Measures: The primary efficacy outcome was the proportion of randomized subjects reporting “no vaginal laxity” (Active vs Sham) at 6 months postintervention, which was assessed using the Vaginal Laxity Questionnaire. Treatment-emergent adverse events were evaluated in all treated subjects. Secondary efficacy end points included change on the Female Sexual Function Index (FSFI) and the revised Female Sexual Distress Scale (FSDS-R).
Results: No vaginal laxity was achieved by 43.5% and 19.6% (P ¼ .002) in the Active and Sham groups, respectively. Differences in FSFI and FSDS-R total scores (Active vs Sham) were 1.8 (P ¼ .031) and “2.42 (P ¼ .056), respectively, in favor of Active treatment. Treatment-emergent adverse events were reported by 11.1% and 12.3% of subjects in the Active and Sham arms, respectively.
Conclusion: The VIVEVE I trial is the first randomized, controlled, blinded, clinical study of RFc for the treatment of vaginal laxity. A single treatment of RFc therapy was found to be safe and associated with both improved vaginal laxity and improved sexual function. The results from this trial support the use of a novel nonsurgical therapy for vaginal laxity, a prevalent and undertreated condition.
