NCT05097573

Brief Summary

This is a prospective, single centre, evaluator-blind study of the performance of fractional radiofrequency (RF) for the treatment and revision of stretch marks. The study will evaluate the progress of 15 subjects requesting treatment of stretch marks. The study will involve four treatments on both sides of the face with 4 week intervals between each treatment. Subjects will be followed at 12 and 16 weeks after their last treatment. Analysis will be performed on all subjects who receive at least one treatment.

Outcome Measures

Primary Outcomes (2)

  • Percent Change in Volume of Striae Via Antera 3D Imaging System Analysis From Baseline to 16 Weeks Post-final Treatment

    Change from baseline to the follow-up visit 16 weeks post-final treatment as a percentage of baseline volume.

    16 Weeks Post-Final Treatment (Week 28)

  • Overall Stretch Mark Improvement From Baseline to 16 Weeks Post-Final Treatment Assessed by the Global Aesthetic Improvement Scale (GAIS)

    Evaluate the efficacy of overall stretch mark improvement assessed live by the Investigator and a subject assessment of stretch mark including the Global Aesthetic Improvement Scale (GAIS).The Global Aesthetic Improvement Scale is a seven-grade subjective test. The PI evaluated before and after photographs and graded them for change. Possible responses were (3) Very Much Improved, (2) Much Improved, (1) Improved, (0) No Change, (-1) Worse, (-2) Much Worse, and (-3) Very Much Worse. For reporting of outcomes, the higher the GAIS value, the greater the improvement (Range -3 to 3).

    16 Weeks Post-Final Treatment (Week 28)

Secondary Outcomes (3)

  • Subject Satisfaction

    16 Weeks Post-Final Treatment (Week 28)

  • Subject Scale - Visual Analog Scale for Pain

    Treatment 1 (Week 1), Treatment 2 (Week 4), Treatment 3 (Week 8), Treatment 4 (Week 12)

  • Subject Scale - 5 Point Scale for Treatment Tolerability

    Treatment 1 (Week 1), Treatment 2 (Week 4), Treatment 3 (Week 8), Treatment 4 (Week 12)

EXPERIMENTAL

The Venus Viva™ fractional RF device has been shown in clinical studies to improve various skin conditions related to aging and alter collagen structures such as wrinkles, rhytids, stretch marks and scars. Beginning with the Baseline visit (Visit 1), subjects will receive a total of 4 treatments approximately 4 weeks apart.
