Clinical Trial Summary

The goal of this prospective, single-arm clinical study is to gather quantifiable data on Renuvion's impact on skin elasticity and hydration, indicators of skin quality and estimate the biological skin age using DNA methylation in males and females between 18 and 75 years of age who plan to receive a lower facelift surgery. The main purpose is to quantify the effect of the Renuvion device on skin elasticity (collagen density, elastin, fibrillin-1), hydration (aquaporin-3, acidic glycosaminoglycans, HA), and DNA methylation to estimate the biological age of the skin. Participants will receive a lower facelift surgery per the Investigator's standard clinical practice and treatment with the Renuvion APR System.


Description:

The purpose of this study is to gather quantifiable data on Renuvion's impact on skin elasticity and hydration, indicators of skin quality and estimate the biological skin age using DNA methylation. This study is a prospective, single-arm clinical study to be conducted at up to three clinical sites in the US. Up to 10 subjects will be enrolled and treated if they meet the inclusion/exclusion criteria and provide written informed consent. Enrolled subjects meeting all entrance criteria and confirmed eligible for study treatment will be asked to participate. Subjects will receive a lower facelift surgery per the Investigator's standard clinical practice and treatment with the Renuvion APR System. The mid/upper-face area will not be treated with Renuvion and the lower face/neck area will be treated with Renuvion. Treatment will consist of subdermal coagulation of soft tissue using the Renuvion APR handpiece.

Outcome

Type Measure Description Time frame Safety issue
Primary Analysis of Elasticity (collagen density, elastin, & fibrillin-1) To assess Elasticity (collagen density, elastin, & fibrillin-1) evaluation will be based on the qualitative microscopic observation of the stained sections comparing baseline samples to follow-up samples. Histology and immunohistochemistry (IHC) part of the study will be assessed semi-quantitatively. Thus, there will not be units of measurement e.g., weight and height for these evaluations.
Semi-quantitative scoring for any microscopic changes (H&E staining) and enhancing collagen production (e.g., trichrome staining).
Four-point Severity Scale Semi-Quantitative Grading of Changes in Histology Samples Description - Definition Normal - Tissue is considered to be normal Minimal - The amount of change present barely exceeds normal limits. Mild (Slight) - The amount of change is easily identified but limited severity. Moderate - The amount of change is prominent, but significant potential for increased severity.
Severe - The degree of change is as complete as possible
Baseline, Day 180
Primary Analysis of Hydration (aquaporin-3, acidic glycosaminoglycans (GAGs), hyaluronic acid (HA)) To assess Hydration (aquaporin-3, GAGs, HA), evaluation will be based on the qualitative microscopic observation of the stained sections comparing baseline samples to follow-up samples. Histology and immunohistochemistry (IHC) part of the study will be assessed semi-quantitatively. Thus, there will not be units of measurement e.g., weight and height for these kinds of evaluations.

Baseline, Day 180
Primary Analysis of Adverse Events Analysis of adverse events through the 180-day post-treatment visit. Treatment, Day 1, 7, 14, 45, 90, 180
Primary Analyzing days of duration for Bruising, Swelling Analysis days of duration of bruising and swelling post-treatment through the 180-day visit. Post-Treatment, Day 1, 7, 14, 45, 90, 180
Primary Days to healed percentage Analysis average number of days to healed profile post-procedure through the 180-day post-treatment visit through Case Report Forms through percentage healed at each follow-up. Post-Treatment, Day 1, 7, 14, 45, 90, 180
Primary Bleeding Analysis of bleeding during surgery measured in cubic centimeter. During Procedure (Day 0)
Primary The Principal Investigator will complete a PGAIS assessing overall aesthetic improvement in the treatment area at day 45, 90, and 180 post-treatment. Global Aesthetic Improvement Scale Evaluation (PGAIS) rating by investigator [Very much improved, Much improved, Improved, No change, Worse, Much Worse, Very much Worse] Day 45, 90 and180
Primary The subject will complete a SGAIS assessing overall aesthetic improvement in the treatment area at day 45, 90, and 180 post-treatment. Subject Global Aesthetic Improvement Scale Evaluation (SGAIS) rating by subject [Very much improved, Much improved, Improved, No change, Worse, Much Worse, Very much Worse] Day 45, 90 and180
Primary Patient Satisfaction The subject will complete a Patient Satisfaction Questionnaire (PSQ) while referring to their image in a mirror and current post-treatment photos compared to baseline photos to rate how satisfied they are, and if they note any improvement in the treatment area. Day 180
Primary Estimated biological age by DNA methylation. DNA methylation (DNAm) will be used to measure the tissue samples to estimate the biological age of the skin. A highly accurate skin-specific age algorithm will analyze these modifications related to human skin health and molecular aging - quantifying the skin health/skin age of the tissue beyond the chronological age of the subject. Hallmarks of aging include genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, deregulated nutrient sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, and altered intercellular communication. Baseline, Day 180
